The recent passing of H.R.5376, the Inflation Reduction Act (“IRA”), has extended the Investment Tax Credit (“ITC”) for solar, and reinstated the Production Tax Credit (“PTC”) for solar through at least the early 2030s. While this legislation is designed to offer tax credit monetization incentives that encourage investment in new utility scale solar projects, basic challenges that face developers remain.

A June 2022 Science Direct study examined 53 utility-scale wind, solar, and geothermal energy projects in 28 U.S. states, that were delayed or terminated between 2008 and 2021. Researchers found that 34 percent faced significant delays and difficulties securing permits, 49 percent were cancelled permanently, and 26 percent resumed after being stopped for several months or years.

A major challenge in project financing is the perception that renewable energy projects are high-risk. The statistics presented in the Science Direct study certainly justify this assumption. That is why due diligence and fatal flaw analysis are critical at the outset. A comprehensive risk analysis framework provides a decision-making matrix defining the critical factors that must be considered, in order to reach a sound decision. It addresses the goals of the investors to ensure that the financial realities of the project are clearly delineated at the outset, and transaction milestones are met. It instills stakeholder confidence, because vital data is easily accessible throughout the development and financing continuum.

Key factors in the decision-making matrix should include:

• Off-taker review and evaluation of the time required for the off-taker to build the transmission line to ensure that it meets project completion deadlines.

• Analyzing the regulatory and tax incentive environment of the project.

• Assessing high-level risk factors associated with the project.

• Examining site feasibility and identifying potential sources of public impact or opposition.

• Assessing the surface vs. subsurface of the land for mineral development.

• Evaluating project impact, if it includes indigenous or tribal lands.

• Conducting a transmission analysis, including load and transmission capacity, to obtain an energy yield assessment.

• Conducting a comprehensive permitting and jurisdictional review.

• Initiating a title search and review.

• Conducting a compliance review to ensure that the project adheres to relevant regulations.

• Overseeing site control to ensure that executed leases or options and easements are in place, and that power can be exported into the grid.

• Structuring a comprehensive timetable for various phases of development. A meticulous business case assessment recognizes the goals of the investors to ensure that the financial realities of the project are clearly addressed. This considers both technical viability and environmental impact, as well as long-term financial soundness. A detailed decision-making matrix diminishes the potential that risk factors will be overlooked. Vigilant due diligence is a critical investment in the success and resilience of every renewable energy project.

A ferry ride set to mark a new Guinness World Record

Electric ferry, Ellen, sailed 50 nautical miles (92km) on a single battery charge during the International Energy Agency’s 7th Annual Conference on Energy Efficiency. The distance marks a new world record. The islands of Ærø and Als in Southern Denmark are connected by Ellen, a long ranging fully electric ferry. Ellen set a new world record on June 9 just outside the windows in Sønderborg, Denmark, where leaders from industry, government, and civil society joined the International Energy Agency (IEA) for the 7th Annual Global Conference on Energy Efficiency. On her return from the conference, where participants explored how international ambition on energy efficiency can be translated into faster and stronger real-world progress, Ellen reached a total of 50 nautical miles (92km) on a single battery charge. Ellen does not emit carbon and operates at 24% lower cost than a new diesel ferry. She started sailing in 2019. Danfoss has supplied electric Editron drivetrains and propulsion motors for the ferry.

Capture CO2 directly from the air

EDAC Labs is commercializing an electrochemical Direct Air Capture methodology, developed by Chao Wang, Associate Professor at Johns Hopkins University, that will capture CO2 directly from the air for utilization and sequestration. Dr. Wang’s team have devised a novel approach to DAC incorporating an electrochemical process which can be 100% powered by renewable energy sources. The resulting process greatly reduces energy consumption and the cost of carbon capture. The aim for this technology is to capture CO2 for less than $100 per ton. Following the successful lab-scale demonstration of its electrochemical DAC technology, Dr. Wang’s team will receive funding from the Johns Hopkins Ralph O’Connor Sustainable Energy Institute to build a demonstration project on campus that is capable of capturing approximately 40 tons of CO2 annually. EDAC Labs was awarded the $1000 grand prize from Maryland Department of Commerce at the Maryland Energy Innovation Accelerator Pitch Event.

Sustainable Path Toward Succession

As a business owner, you've spent years building your business and hiring the right people for the right job. That responsibility doesn't end once you decide to step away; in

important. In this article, we'll take a closer look at some of the roadblocks

when creating a succession plan, as well as the steps that you should take to help ensure the future success of your business.

Common Roadblocks


to plan too late

Chances are, you have a lot happening on any given day, and that may not include planning for succession — until it's too late. Before you start planning for retirement and beyond, you need to seriously begin thinking about what's going to happen once you're gone. While there's no cut-anddried answer on how long this can take, on average, you should plan on an effective succession plan taking anywhere from 12 to 36 months, from beginning of planning to completion.

…No formal plan in writing

Simply having verbal promises in place isn't enough for an effective succession plan. Everything pertaining to this plan should be put down in writing. A written process, such as who will be taking on what, what important aspects of the business will be affected, and the value of your company should be included here. Never assume that important information, such as internal processes, is widely known by others within your company. Include detailed information about your role and responsibilities within your succession plan.

…Not involving professionals

With a succession plan often comes legal implications. If you take the necessary steps to prepare for these issues as soon as possible, the smoother the transition will be. If you're not already working with a business attorney by the time you start planning succession, this is a great time to start. Moreover, when a business changes hands, there may be additional taxes that are owed, which correlate with the value of your company. When this valuation process is done correctly, with the help of professionals, it will make it much easier to figure out how much is owed.

…Choosing family as successor

77 percent of small businesses in the United States are familyowned. This can add an additional layer of difficulty when it comes to choosing someone to take over the company. In fact, almost 75 percent of family-owned businesses fail to pass beyond the first generation of owners; that number increases to 85 percent by the second generation, with 95 percent failing beyond that. These numbers can be tied back to a number of factors, including family conflicts, informal leadership roles, lack of communication, and more. Before you decide to have a family member take over, gauge their willingness and qualification to be a part of the next chapter.

…Pushback from the inside

If those within your business push back against your plan, the chances of it being successful narrow down. While there's no way to make every single person 100 percent happy, you can make compromises (where possible) to help ensure people are onboard. For example, you can identify more than one person to potentially take over a role, and then come up with a list of criteria with other decision-makers to give everyone a fair chance to take over.

5 Steps for Creating a Succession Plan

Because every business is built differently, there isn't a "one-size-fits-all" solution for succession. There are, however, general steps you can take to help ensure a smooth and easy process. A succession plan isn't a one-and-done process. It should be thought of as a living document that needs to evolve with your company when new challenges and issues arise.

1. List out the challenges that both your business and industry may face

You've been around long enough that you've faced and overcome a lot of adversity. By identifying the challenges your business may face in the future, you can come up with the right moves to combat them beforehand, helping you to save time and resources. Break these down into short-, mid-, and longterm issues. The more specific these are to your business and industry, the better prepared you'll be.

2. Identify important roles within the organization

Throughout your tenure, you've worked closely with many in your company, so you know which members of your organization are critical to your success. With some of these replacements, you may know in advance that a role will need to be filled (such as a planned retirement), but in other situations, it may be a surprise. Either way, it helps to have a contingency plan in place to replace these roles quickly, helping to reduce knowledge gaps.

3. Target potential replacements for these roles

Once you identify the employees that will potentially need to be replaced, you can come up with a plan to find the best fit for them. Don't forget that the right fit may not be too far away. There are several benefits when it comes to promoting from within, including improved company morale, lower costs associated with the hiring process, and more empowered employees. Don't forget to include back-ups in the event your first pick is unable to take over.

4. Implement a career development plan

Once the employees and proper replacements have been identified, come up with a plan that is as detailed as possible. This should include a handover period, where the new person works alongside their counterpart, taking on more responsibility over time. Not only will this provide an employee with the opportunity to gain first-hand experience in the role, but it'll help capture the knowledge needed to be successful in that role, so you don't lose anything during the transition.

5. Finalize a transition timeline

Now that you've collected all of the pieces, it's time to put everything together. While you've taken every precaution during the planning, the unexpected can still happen. By creating a plan that allows for these hiccups, you're more likely to stay on track. If plans keep getting pushed out, it may cause people to seek opportunities elsewhere, putting you and your plan back at square one.

Solving Solar’s Biggest Challenges

The supply chain issues and skilled-labor shortages plaguing the solar industry are very real, and they have indeed slowed the industry’s growth. But given the environmental, economic, and geostrategic forces aligning behind solar energy, the most pressing problem solar faces is to figure out how to deploy as many photovoltaic (PV) systems as humanly possible, as efficiently as possible.

Consider just a couple of data points. Experts estimate that, to get to net-zero greenhousegas emissions by 2050, we must install 455 gigawatts (GW) of additional solar capacity globally each year through 2030. For comparison’s sake, the total U.S. installed solar capacity stood at about 121 GW as of early 2022, and that of China – the world’s largest solar energy market – at perhaps 350 GW. In other words, each year, the world must now deploy roughly as much solar as has ever been installed in its two largest economies.

To get there, the solar industry must solve three major long-term challenges. First, it must reduce the soft costs that comprise more than 60 percent of residential solar PV system outlays. Second, it must turn projects quickly both to boost scale and stem the tide of project cancellations dogging the industry. Third, it must develop efficient supplier and subcontractor networks to enhance collaboration and efficiency.

Fortunately, a new class of intelligent software – collectively called solar deployment operations management – is arriving at just the right moment. These cloud-based solutions, which combine the strengths of project, asset, and work-management software, are capable of tracking and managing thousands of job sites, assets, and field crews in real-time, and much more. Let’s consider solar deployment management in the context of those three challenges.

1. Cut soft costs

With respect to reducing soft costs, solar deployment management solutions include such features as standardized project templates, automated document generation, and easy-to-use mobile forms for field technicians. While every solar project has its unique

aspects (and these systems are customizable to reflect that), standardization along best practices cuts redundancy, avoids mistakes, and speeds the pace of work. These systems also manage site candidates, approvals, and drawings, and they match deployment assets with job sites to ensure that equipment is where it needs to be, when it needs to be there. They also centralize permitting workflows from submission to final approval, further cutting soft costs and shortening project timelines.

2. Turn projects fast

Shortening project timelines is an essential element of the second long-term challenge of turning projects quickly. The standardized templates and other features mentioned above also come into play here. So does the automation of complex business processes such as managing capital funding budgets, tax credits, and incentives, as well as the drawing approvals needed to get projects to closeout faster.

Solar deployment operations management systems do more than track. Their machine learning capabilities help forecast project milestones and overall completion times based on inputs from project managers, vendors, jurisdictions, and market conditions. Analytics deliver insights through tailored reports and dashboards, further improving project cycle times and field performance. These artificial-intelligence-powered systems can even help select the best vendors for specific jobs, and inform financing decisions.

Solar deployment operations management is playing a significant and growing role in financing, particularly in commercial solar. By providing granular visibility into dozens, hundreds, or thousands of projects, organizations can demonstrate a detailed track record and give lenders a true sense of the risks and probable ROI of signing on.

3.Build & sustain solar-deployment networks

Solar deployment management solutions also address the solar industry’s third longterm challenge of developing efficient supplier and subcontractor networks to enhance collaboration and efficiency. These systems bring contractors into the fold to enable collaboration on project schedules, job information and images, and site maps and history to deploy faster and at lower cost. Further, against a backdrop of skilled-labor shortages, these systems’ ability to place scarce resources at the right place at the right time is increasingly vital. The aforementioned standardized processes also embed industry and organizational knowledge into workflows that empower less-experienced staff to perform at higher levels, and with less supervision than otherwise possible.

Underpinning all the advantages of solar deployment operations management systems is the single source of truth their cloud architectures afford. Having one holistic system to manage sites, assets, field work, finance, and other functions brings far better visibility into operations, faster and more efficient deployments, and a quicker path to profitability than otherwise possible.

The days of relying on general construction management software, spreadsheets, or disparate systems for project management, financial management, asset management, field-crew management, and other functions must end if the solar industry hopes to achieve anywhere near the growth the market will embrace in the coming years. Solar deployment operations management systems will be essential in exploiting the vast opportunities – and overcoming the many challenges – ahead, as the solar industry strives to fulfill its enormous potential in realizing our clean-energy future.

From Landfill to Solar Farm

What is one of the most intriguing U.S. solar development opportunities involving thousands of otherwise unusable sites ready for dozens of gigawatts’ worth of solar energy projects? The answer lies on oftenforgotten, vacant acreage found in communities around the country: solar farms on capped and closed landfills.

Rocky Mountain Institute’s recent report, “The Future of Landfills Is Bright,” puts the solar market potential of capped landfills at 63 GW in the near future—enough generation of power to light up 7.8 million U.S. homes. Yet, so far, only 500 megawatts (MW) of solar projects on landfills have been built. Most of these are in Massachusetts, Connecticut, New Jersey and New York. States like California, Texas and Illinois have yet to see many of these landfill sites developed for their clean energy generation potential.

Landfill solar benefits and challenges

In addition to the obvious positives - clean energy, decarbonization, and pollution abatement - there are other benefits of solar farms on landfills. The projects create construction and operational jobs, put otherwise unused or underused land to productive use, generate tax revenues for local and regional governments, and provide lease revenues for landowners. These projects also typically avoid landuse restrictions and challenges from NIMBYism that derail some clean energy projects.

But developing, building, and interconnecting solar arrays on landfills is not a cookie-cutter endeavor— no two projects are engineered alike. Each project requires careful and consistent coordination among local governments and communities, property owners, utilities and developers, engineering, procurement and construction (EPC) firms and their subcontractors, as well as other stakeholders in order to reach a successful outcome. Developers and EPCs that have experience in successfully deploying solar on landfills can help ease the challenges. Collaboration and clear channels of communication are critical, especially between the utility, developer, and EPC engineering teams, all the way from design to permission to operate (PTO).

Don’t mess with the membrane

When planning a solar project on any closed landfill site, there’s one golden rule: the membrane or liner of the capped landfill cannot be breached or compromised in any way during the construction and operation of the PV (photovoltaic) array. The release of methane, carbon dioxide, or other hazardous materials from the closed landfill would be a nonstarter, both in terms of safety and the structural integrity of the system. Site earthworks and grading must be limited, ground settlement accounted for and avoided where possible, and site characteristics such as shading, flood plains, and terrain undulation must be engineered into the system.

With these limitations, landfill sites require thoughtfully designed PV systems that do not penetrate the ground on the capped area, starting with ballasted racking systems with low weight loads. Inverters, transformers, and other equipment must be positioned for both maximum system performance and minimal site disturbance. For some landfill projects, the grid substation should be located close to the site; trenching and cabling often has to skirt the edge of the landfill caps to reach the interconnection points.

Case Study: Belleville Solar Landfill

One of the more notable recent capped landfill solar projects is located in Belleville, Ill. The 13.3 MW-DC ballasted, fixed-tilt ground-mount system is one of the largest of its kind in the U.S. It was completed and connected to the local utility grid in late 2021, and is now generating enough electricity to power more than 2,160 area households. The project involved a sub-transmission interconnection, which is a high-voltage system that takes power from the higher voltage transmission system and reduces it to a lower voltage for more convenient distribution to nearby load centers.

The unique challenges and opportunities of turning waste into a clean energy asset

Close collaboration is key

During the course of the Belleville project, frequent communication became critical to share expertise in large-scale solar design and understand interconnection requirements. It took a year of close collaboration to finalize specific technical requirements, such as protection schemes and relay settings, before the project reached PTO and the system was ready for witness testing.

The Belleville project required the development of interconnection policies and procedures for the solar farm’s subtransmission system, which feeds power to the distribution grid. Since the output of the Belleville facility was large, it had to be put on a 34 kV system, the backbone for all the distribution-level voltages that directly serve the utility’s customers. The ultimate goal was to ensure that the project would maintain high service reliability levels.

Another key challenge on the Belleville site involved the line electronic recloser, a utility-scale circuit breaker designed to disconnect the site from the grid after detecting abnormalities. The size of the project required adding the recloser, which is typically not needed in smaller, more standard solar plants. The team had to determine the range of potential anomalies the recloser needed to detect for the required settings to be finalized. This complex process helped to reassure the developer that the implemented protection schemes would be effective.

Unique EPC challenges

Each capped landfill project presents its own set of unique engineering and construction challenges, and the Belleville site was no different. Here are some examples:

• Precast ballasted foundations were used to secure the arrays without penetrating the landfill.

• Eleven separate transformers were installed for this project to distribute the weight more evenly, rather than the one to three typically used for a non-landfill project of this size.

• Cable trays were employed instead of trenching or boring electrical wires.

During the construction process, the team had to be careful to not have any heavy machinery on the landfill site and work around the landfill cap. The facilities could only be built in designated areas, since trucks and equipment could only go through specific routes to install and maintain the facilities. Additionally, all the equipment to the site had to be transported using a specific type of dump truck instead of the cranes and larger trucks typically seen with non-landfill projects.

Lessons learned

The larger-scale Belleville project reinforced the benefit of establishing a collaboration between the utility and an experienced solar EPC in order to refine the process and mitigate challenges. As more utilities work with solar projects of this size, a focus on safety at all stages is critical to the project success, from the planning and construction to the policies and procedures for the system to operate. Finally, close collaboration between the EPC, utility, and system owners is a key indicator of overall project success.

The Belleville project was developed and is owned and operated by The AES Corporation (AES). Republic Services owns the landfill. The project is connected to the Ameren Illinois utility grid.

Tips to Reduce Time, Money, and Stress

Practical advice for utility-scale PV + BESS control system development and commissioning

One of the keys to unlocking the full potential of renewable energy is battery energy storage. Nowhere is this more evident than when coupled with photovoltaic (PV) power plants. According to the U.S. Energy Information Administration, battery energy storage capacity tripled in 2021. Additionally, 93 percent of the battery capacity added last year was co-located with solar.

It’s said that the only thing better than learning from your own mistakes is learning from someone else’s. There are two primary architectures for coupling BESS with PV: DC-coupled and AC-coupled. The following tips are based on lessons learned from developing and commissioning AC-coupled BESS and PV projects (Figure 1).

Tip #1: A control system functional specifications is a must

Generally, the project design package will include a detailed design for the substation, the PV array, the BESS lineups, and communications for control and SCADA. Projects with the highest success levels will also include a comprehensive control system functional specification, a document detailing the control system's capabilities, constraints, appearance, and user interaction.

The requirements for how the controls system will meet interconnection agreement (IA) and power purchase agreement (PPA) power plant requirements will be contained

within the specification. Using the functional specification, the system integrator develops a detailed plant control narrative (PCN) and SCADA design, along with an itemized quality assurance checklist. System integrators that begin design and development without a functional specification will risk significant rework and project delays during system commissioning.

Tip #2: Require a Factory Integration Test (FIT) for new products

Lack of product maturity and market volatility represents a significant risk to system integrators. Executing a factory integration test (FIT) prior to, or within the project, is one way to mitigate this risk. Typically, the owner and engineer of record participate in the FIT. As part of the FIT, the system integrator will configure the SCADA system's power plant controller and elements to verify the factory's functionality and performance.

A detailed test procedure is developed and agreed to in advance by all parties. The system integrator and manufacturer conduct and document the test, making adjustments along the way. It's important to document the equipment firmware revision at the end of the test, as any modifications moving forward can significantly impact future commissioning. The FIT is also the perfect opportunity for the system integrator to develop a relationship with support personnel, thus, streamlining future support.

Tip #3: Pin down electrical metering early in development

Electrical metering is critical to the operation of any power plant – for both revenue tracking purposes, and providing the primary feedback variable for power plant control. Therefore, most designs include both primary and backup meters. In addition, virtual (calculated) meters may be required to satisfy the functional requirements. Additional considerations include using compensated or uncompensated values within the control algorithm.

Meters must be configured appropriately for voltage, current, and power flow direction. Furthermore, the correct assignment of analog outputs is important if hardwired inputs to the control system are required. Substation end-to-end testing is the ideal time to test and verify metering, as the engineer of record is typically on-site, and issues can be quickly resolved and easily documented.

Tip #4: Don’t forget about the mechanical systems¬

PV+BESS are predominantly considered electrical systems, but your power plant will operate at less than optimal if mechanical systems are not properly managed, operated, and maintained. For PV, this can include the tracker system. For BESS, this includes the container systems for climate control, fire suppression, and access. The system integrator should refer to the control system functional specification to determine the systems and points that need to be integrated for the mechanical systems.

Figure 2: Use High Resolution Trending to Tune Controls

Most of these systems will be provided as packaged systems. For systems that do not come with packaged controls, the system integrator may need to account for the control within the control system design and development. Like the electrical systems, the mechanical systems must be thoroughly commissioned. Tracker systems not operating properly will result in reduced system output; problematic BESS mechanical systems result in higherthan-expected auxiliary loads reducing battery system capacity. Lastly, don’t forget to test the fire suppression system, as this system is important to suppressing a thermal runaway condition.

Tip #5: Verify networks before hot commissioning of field equipment

This tip sounds intuitive, but it should be a high priority on the control system pre-startup checklist. Network cabling integrity is easy to confirm, and can significantly reduce time wasted isolating and troubleshooting communication issues, especially considering that most utility-scale solar farms are a minimum of 200 acres, with the largest plants in the 1000s. Reducing the time in the field, not to mention exposure to environmental conditions and safety hazards in extreme locations, will lead to a more positive commissioning experience.

Recommend that the data-comm installer provide reports as evidence that cabling has been terminated and tested. Get to know the field team that is performing cold and hot commissioning of the equipment; they can save you time in the field if they are able to assist with verifying equipment communications.

Tip #6: Take advantage of early power plant testing

Most plant controls can be tested with only partial operation. Electrical systems are generally organized based on substation feeders. Start plant control testing when the first feeders come on-line. This approach allows more time for verification, documentation, and remediation. Resources are more readily available at this point in the commissioning process. Additionally, starting early allows system integrators to work around unpredictable conditions, such as equipment failures or weather conditions.

If you do choose to wait until the end, be prepared to endure significant pressure. Once all equipment is online, all priorities will be focused on the commercial operation date (COD) milestone. Remember, time is money!

Tip #7: Use high-speed trending when tuning control loops

During power plant testing, high-resolution data analysis is required to understand and tune control. Avoid the temptation to use the SCADA system historian. The issue with using SCADA is the latency along with the data resolution. Instead, use the highspeed trending capability of the automation controller for optimal results. Figure 2 shows an example of a plot for verifying the startup of a PV plant.

Unique Roof Design for Minimal Environmental Impact

If reading, writing, and arithmetic are the hallmarks of excellent elementary school education, the Annie E. Fales Elementary School in Westborough, Mass., is one of the best, ranked in the top 20 percent for overall test scores among nearly 1,700 public schools in the Commonwealth. With its newly built, net zero-designed facility, the school has earned an A+ not only for the quality of education, but also for its impact on the environment.

The new school, designed by HMFH Architects of Cambridge, Mass., which specializes in educational facility design, is setting a precedent for energy-efficient design in educational facilities as the first net-positive energy public school in Massachusetts. In addition, the project has been recognized by a major roofing system manufacturer as a ‘2021 Project of the Year’ in the ‘Sustainability’ category for the outstanding roof installation by an approved contractor.

“The town of Westborough has a goal of becoming carbonemissions free by 2035,” said Caitlin Osepchuk, AIA, HMFH Associate. “The entire facility -- from its site on the side of a hill, and geothermal heating and cooling system, to its centralized energy management system designed to use one-third of the energy typically used in a school of this size, highly efficient curtain wall system, LED lighting, triple glazed windows, and its unique roof structure – was designed to minimize impact on the environment.”

The 58,000 square foot roof is indeed a unique aspect of the building, featuring 11 different raised sawtooth profiles each

designed to both “optimize the amount of natural daylighting in the classrooms, and to provide the best orientation for the building’s solar array,” said Osepchuk.

In total, the facility has over 1,350 solar modules, capable of producing 507.75 kw of electricity, said Stephen Coffrin, senior project engineer with Solar Design Associates of Harvard, Mass. The solar panels were installed on a rail-based system and secured to the steel deck with universal roof mounts.

The solar array was specified with modules rated at 375-watts each with half-cut cell technology to increase the energy output by reducing the size of the cells so more fit on the panel. Individual panels are ‘split’ in half, so the top of the panel operates independently from the bottom, which provides more energy even if part of the panel is in shade.

The modules are near the top of their class in overall efficiency at 21.4%, have industry leading warranties on their power output (25 years) and physical product (20 years), and are tested to withstand the increasing wind and snow loads associated with

New England weather (95 pounds-persquare-foot snow load, 55 pounds-persquare-foot wind load).

The monitoring system displays module level production, greatly increasing reliability, uptime, and reducing O&M costs. Consumption monitoring is also provided to allow load-to-generation ratios to be examined.

The roofing system, installed by Capeway Roofing Systems, Inc., of Westport, Mass., includes a 22-gauge metal deck, vapor barrier, two layers of 2.6-inch polyisocyanurate insulation, and a layer of tapered insulation over the top for positive drainage, all mechanically attached to the deck. A half-inch gypsum cover board is fully adhered over the top. The waterproofing layer is reflective gray 60 mil PVC membrane with an adhesive backing on the sloped portions of the roof, and 60 mil white PVC membrane on the flat sections.

We use lots of this membrane,” said Michael Correia, project manager for Capeway Roofing. “It’s a good time saver for us since you just lay it down and roll it in, and it’s easy to work with. Our guys really like it.”

The 11 sawtooth profiles range in overall length from 65- to 187-feet long, with slopes on the southern or solar panel side ranging from 21° to 30°, and slopes on the northern side for daylighting ranging from 54° to vertical. The individual sawtooth heights from the roof deck to the peak range from seven- to 12-feet.

The original goal for the Annie E. Fales Elementary School was to build a net-zero energy facility. Based on the early data collected, it is now fully expected that the facility will actually be net-positive energy by the end of the first year, using less energy than it generates, and earning a solid A+ on its first-year report card thanks to the great work by all involved.

In addition to the membrane installation, the roofing contractor also installed about 1,600 of the universal solar roof mounts which can be used on any type of commercial roofing system and offer superb strength to resist tensile, shear, compressive and moment forces. The screws become load-bearing columns which work in both tension and compression, making the mounts ideal for managing moment forces created by gravity and snow load on a sloped roof. Additionally, the universal mount has two, independently functioning, water blocking systems designed to maximize long-term performance.

“We specified these mounts as they are ideal for the saw tooth application and offer the best strength and the best chance for the roof to remain watertight,” said Coffrin. “The product is designed with redundant barriers in the base plate and the top plate and then secured directly to the deck.”

Installing the 1,600 roof anchors on the slopes of the saw tooth structures meant that Capeway had to ensure that each was located properly for the solar rail system that would later be installed. Once the roofing membrane was installed, the solar specifier came back to the jobsite and snapped horizontal and vertical lines to precisely indicate where each universal roof mount was to be installed.

“Installation of the 1,600 solar mounts went faster than anticipated,” said Correia, who supervised the installation, “and we were impressed with the productivity. This was our first time with these specific units, and we liked the fact that there is nothing to heat weld, which made the installation more productive than we originally anticipated. It also helped the solar installation to start a bit early.”

Corrosion in Solar Support Structures

Atopic of increasing interest in the fast-growing solar industry is corrosion abatement in solar support structures.

Corrosion is the deterioration of a material that results from a reaction with its environment. Experts estimate the economic impact of corrosion on an economy to be 3-6 percent of a country’s gross national product (GNP). According to the article "Economic Effects of metallic Corrosion in the United States", published in 1978 by the Battelle Columbus Institute and the NIST, contains calculation to determine the economic effect (equations), which was then used on data from 1995 to determine that year’s cost of corrosion: nearly $300 billion, or ~4.2 percent of GNP.

Since this early economic assessment, new coating technologies have been developed and applied to combat corrosion. These include metallic coatings such as zinc and zinc alloys, polymer-based coatings and paints, epoxies, sol-gel coatings, and hybrid coatings with high solids content applied by liquid or dry powder spray techniques.

Additionally, construction, assembly and building practices have evolved to combat corrosion, as has component design. This is particularly true for the automotive and construction industries. Designs are increasingly engineered for easy water runoff and drying, and there has been a significant reduction in metallic seams, laps, and joints where water, dust, and other contaminates can create corrosion cells.

Figure 1 below depicts a solar pile, to which solar modules would be attached, where it is driven into the ground. Three primary zones of corrosion are shown – atmospheric, ground level, and below ground – each with differing rates of corrosion.


In atmospheric corrosion, one should consider the location-based wet-dry cycles due to normal weather patterns. Locations near the ocean (< 2 kilometers) may be subject to chlorine ions from salt spray. In locations near industrial areas and highways, pollutants like sulfur increase atmospheric corrosion. Furthermore, higher ambient temperatures increase corrosion rates.

Design for the Site, Not the Racking

As the solar industry looks to build in more challenging terrains, particularly colder climates, the potential for high impact and costly errors when designing must be considered in pre-project planning. Across the Northeast states and Canada, geotechnical investigations have identified several common project design pitfalls that can be avoided by following a set of best practices.

1. Prioritize risk management and reduce costs through proper site assessment

The entire industry is facing narrowing margins. As a result, managing risk and reigning in costs are key to a project’s success. One way to achieve this is to thoroughly understand your solar project site conditions; bringing in a well-trained geotechnical engineer early on in the project cycle will reduce the number of unexpected or unforeseen issues with materials procurement and site construction. This individual should have experience with the site’s climate and potential subsurface conditions, especially if you are going to be building in a colder climate, areas subject to high wind conditions, or those affected by seismic activity.

Geotechnical engineers will also help you to optimize your foundations; these are an untapped source of cost savings, and can provide outsized value for the cost of investment. Even such minor optimizations as pile lengths can result in significant savings when multiplied over the size of the site. Partnering with an engineering firm specializing in solar foundation design not only prevents issues, but is also proactive in increasing the value of your site.

2. When to bring in a geotechnical engineer

As a general rule, the larger the solar project, the more potential there is for site variations and complex subsurface conditions. For a microgrid site (300-600 kW), a modified geotechnical investigation is the recommended course of action, since the upfront investment in a comprehensive geotechnical investigation may not result in corresponding savings and risk reduction. The modified geotechnical investigation would typically result in more conservative recommendations. For any site smaller than 300 kW, a preengineered system should perform sufficiently well and not gain any savings from a geotechnical investigation.

Utility-scale sites (those larger than 600 kW) will benefit from a comprehensive geotechnical investigation; this provides a greater return on investment through reducing the steel costs, as well as greater confidence in the performance of the foundations. The cost of a geotechnical investigation is generally a smaller portion of the budget. A comprehensive geotechnical investigation includes soil testing on-site, in-situ pile testing, and a refined design optimized to the site’s particular conditions.

3. Let the site do the talking (not the racking supplier)

You may hear from a racking supplier that they recommend groundscrews or helical piles for a colder site. But, without a geotechnical report in hand, these recommendations may be more aligned to the foundations that fit their racking rather than the foundation design that will perform best when considering the site-specific subsurface conditions. Other solutions for colder climates, such as using technologies to reduce frost uplift through a frost sleeve or rigid insulating the pile with foam board, may result in embedment reductions that will often reduce cost while meeting engineering requirements.

4. Climate considerations

There are three primary climate considerations that can result in minor to severe damage to a solar project: frost and wind uplift, gravitational loading, and seismic loading. A seasoned foundation engineer will consider climatic loading in conjunction with subsurface conditions.

You can compensate for increases in frost or wind uplift loads by increasing the foundation size in two ways. Either embed the foundation deeper, or increase the cross-section size of the foundation. An additional measure to address frost uplift involves insulating the foundation, or installing a frost sleeve. This can reduce the load percentage to as low as 20 percent. It’s also an economical solution for weak soils.

A quick note on seismic loading: While generally less of a concern in the Northeast, even in areas with frequent seismic activity, its impact tends to be minor. Seismic loading results in fatigue over time through cyclical oscillations. It typically does not exceed racking tolerances. If this is a concern, larger foundations will help to stabilize projects in areas with high seismic loading.


Subsurface considerations

Subsurface conditions can vary considerably from site to site, and even within the site itself. A geotechnical engineer will review the subsurface conditions and engineering classification of site soils, presence of obstructions or other deleterious materials, and groundwater conditions. For example, if the engineer finds organic-rich materials (which are often problematic for all foundation types), then the design considerations will be impacted.

The subsurface conditions impact several parameters of foundation design, including adfreeze pressures, frost design depths and susceptibility, corrosive nature, constructability, and in-situ moisture conditions.

The climate (how cold the winters get and for how long) is important when designing for frost heave, but soil composition will also affect how deep frost penetrates the ground. Coarser, gravelly sands are more prone to frost penetration than less porous, fine-grained materials. The depth or size of the foundation will have to compensate for the soil conditions in addition to the temperature.

6. Types of foundations

The recommended primary and secondary foundations will differ depending on the climate, soil, and loading considerations mentioned above. Driven piles are the preferred solution, but for sites where you are unable to reach the required skin friction, helical piles will be a good alternative. The most versatile foundation type is a groundscrew; the riskiest is a micropile.

Before you decide on your solar foundation design, bring in a qualified geotechnical engineer early to the project. A qualified professional can help you understand the site conditions and manage the risk. Without engineering expertise, you may end up facing costly rebuilds or repairs.

Rooftop PV Project Permitting

The solar PV permitting process has been involved in an evolutionary struggle: in the early years, from AHJ’s having essentially little or no understanding of PV installations, to now with many AHJ’s developing a full understanding of the details and all of the nuances required to properly evaluate and permit projects. One of the unique aspects of rooftop installations is the guaranteed integration of both verification of building structural adequacy and electrical design upgrades. Recent ASCE code updates have also adopted the SEAOC method of calculating under module lift forces.

As more PV and ESS projects have come through their doors, AHJ’s have increased their understanding of PV system components, fastening methods, and required electrical upgrades (based on the uptick in PV rooftop applications). Incidentally, the review time frames required to permit a PV or PV with ESS project have grown to match that of standard construction projects.

Anything that can be done to shorten the overall permitting time period should be done.

NREL has developed software, “SolarAPP +”, to help AHJ’s more quickly evaluate and permit these projects. Amazingly, in the most populous solar state of California, only 25 out of a possible 530 AHJ’s have signed on to use this standardized permitting platform.

While many US based installers have in-house staff to prepare their own plan sets, a large percentage of the PV plan preparation has shifted overseas (most notably, to India) owing to a combination of lower wage rates and, more importantly, the half day time shift from mainland USA. That time shift allows a project submitted today to receive simple residential plan sets the following morning.

Along with that relatively fast plan set preparation, installers seek additional services to be returned on a short time basis. Specifically, part of the plan submission requires a Professional Engineer (PE) prepared and sealed rooftop structural evaluation and report, along with PE signed/sealed electrical calculations. Interestingly enough, some engineering firms providing rooftop structural engineering evaluations use incorrect methods because they are easy to prepare, not because the results are correct. In areas with little or no snow, using the IBC 5 percent or CBC 5 percent method – essentially weighing the roof in its present condition, and comparing that weight to the roof and solar weight combined – can be a correct evaluation method. Areas with as little as 5 psf snow loading require a different analysis

be individually analyzed. Standard roof framing systems require individual framing member structural analyses, while roof trusses require preparation of a Finite Element Analysis (FEA) demonstrating the entire truss system’s ability to adequately


support the new concentrated loads.

While it is possible for such structural analyses to be done by hand using custom made, proprietary spreadsheets, such analyses can be costly and time consuming, taking over a day, and costing $125 to $250 per single family roof structural analysis along with plan review/sign/seal. Many AHJ’s electrical plans also require an engineer’s approval, which can cost an additional $150 to $250 complete.

Alternate, far less expensive and faster services exist which, for a single low fee, allow PV Designers to enter basic existing building, framing, and electrical information, along with proposed PV design information; within an instant, a structural analysis report is generated, along with any recommended structural upgrades and electrical calculations.

One interesting feature of such services is that these reports can be used by the PV Designer as a design and cost reducing tool by trying different PV module arrangements to minimize or eliminate new structural support requirements, simply by moving PV modules to different parts of a roof’s span.

Once those reports are created, they are followed by a PE’s review of the project’s photographs and drawings demonstrating fealty between the input data, actual field conditions, and the PV design. The customer can expect a return of a finished structural report and reviewed/stamped/ sealed/eSigned structural and electrical plans, in as little as 3 hours.

Complete PE services can be provided directly by entities offering this service, or by third party engineers using these same software platforms.

The advent of the acceptance of third-party signature authentication, or eSignatures, has also revolutionized the permitting process for rooftop PV solar. Many AHJ’s now have portals that allow an organized submission of project applications and drawing sets

electronically, in PDF format. Drawing sets and engineering reports can have Professional Engineer’s seals and signatures applied electronically. The 3rd party authentication of the eSignatures allows AHJ’s to be certain that the documents received are indeed those signed and sealed by the Professional Engineer. At present, the time it takes to get a PV solar construction permit is long, but it can be shortened. And the associated savings in time relate to savings in application and approval costs.

Helping Tenants Access Clean Energy

In June 2022, the Biden Administration announced new executive actions to spur clean energy manufacturing, including invoking The Defense Production Act (DPA) to accelerate domestic production of technologies such as solar panels and building insulation. Historically, the U.S. has struggled to compete with foreign manufacturing of clean energy components, which require a robust supply chain. U.S. energy manufacturing involves investors, scattered suppliers, labor competition, and transportation costs; it’s no wonder that nations who have better optimized their supply chains have won the price competition battle.

The impact of these recent executive actions may not be felt immediately. However, forward-thinking real estate leaders have an immediate opportunity to ride this momentum, and to leverage future investments made in domestic clean energy production. These groups have an opportunity to act now to adopt solutions like solar, home energy efficiency, and monitoring - at scale - to accelerate this U.S. transition to clean energy, one rental property at a time.

More Power to Homeowners, Managers, and Investors

In the next decade, it's predicted that 12 percent of all new homes built in the U.S. will be single family rentals (SFR). Many of these homes are owned by larger investment groups and management companies. The DPA will reduce the costs of adopting clean energy for individual residential customers, as well as property managers owning and operating portfolios of single-family homes.

Lower costs and higher availability of materials will make energy efficiency retrofit projects in the SFR market more viable. Homes that have been upgraded with renewable generation, efficient appliances, and energy monitoring are transformed from sources of strain on the grid, to potential assets for decarbonization and utility support. What’s more, reducing emissions produced by millions of single-family homes will propel the real estate industry toward a more sustainable future.

Amid all the momentum driven by legislation and heightened private sector innovation, many American renters are still left out of the equation when it comes to residential clean energy technologies. Supply chain and cost barriers aside, we have an abundance of options for retrofitting homes to increase energy efficiency and boost clean energy production. Since renters do not own their homes, most don’t know how or if they can approach these upgrades. By leveraging local and national incentives and price structures to bring these technologies to entire portfolios at scale, SFR owners and management companies are not only lowering their carbon footprint, they are introducing more Americans to the benefits of a sustainable and efficient home. Owners that pursue clean energy projects in their rental communities are

Market factors, demand, and favorable legislation will bolster growth for clean technologies across the single-family rental sector

investing in the planet, and laying the foundation for their renters to one day become homeowners with mindful energy-efficient habits.

The DPA makes the integration of clean technology more accessible, both through new home construction and existing home upgrades. Many of the materials needed to complete these projects will be manufactured in the U.S., eliminating international fees or tariffs, and shortening wait times for production and delivery. And, with a two-year bridge on select solar imports from countries like Cambodia, Malaysia, Thailand, and Vietnam (currently in effect), any essential technologies or components that cannot be sourced from U.S. manufacturers will also be lucrative options for maintaining momentum of clean energy projects.

More reliable access to quality materials, from a broad variety of U.S. and international PV and battery technology manufacturers, will help SFRs reduce the carbon footprints of their portfolios - and better utilize the clean energy they generate and store. Opportunities for improving energy efficiency in SFRs are widespread; they extend beyond just energy generation and addressing inefficiencies such as improper insulation or outdated appliances. The emissions reductions that come with clean energy sourcing and enhanced energy efficiency can also serve as strong ESG proof points in real estate portfolios for investors and developers.

Taking Efficiency from Rental Communities to the Grid

U.S. reliance on foreign countries (i.e., China) has disrupted the energy supply chain, and significantly impacted the clean energy industry by extending the timelines for residential and commercial clean energy projects designed to lower emissions and support utilities in their efforts to modernize grids. The DPA will strengthen our domestic solar and grid manufacturing industries, and help lower utility costs. Coupled with low- or no-tariff imports of components from international suppliers, we’ll see increased availability and a greater variety of technologies; even small-scale retrofit projects, like those

owned by SFRs, will be able to contribute to meaningful change in clean energy generation and smarter energy use.

As the industry, and society at-large, waits to see how the DPA will go into effect, SFR operators must act on this opportunity to lead meaningful change. These executive actions have been introduced at a time of increased consumer demand for clean energy and home efficiency technologies. Heightened awareness of the lasting impact inefficient homes can have on the environment presents the perfect opportunity for property managers to invest time and resources into upgrading the efficiency of their portfolios.

DC-Coupled Solar Plus Storage

Electrical system design challenges

At the very start of the process, a DC-coupled electrical system design is a challenge that requires complex analysis. The batteries need to be balanced across the DC/DC converters, and each converter should be balanced through the photovoltaic (PV) DC/AC inverters. In a typical AC-coupled system, AC inverters range in size from 3MW to 4MW, if a central inverter is being utilized. Currently for DC-coupled systems, the most readily available commercial DC/DC converter is 500kW, or a 1/6th to a 1/8th of the size, which creates restricted battery sizing requirement and requires design analysis. As such, it is difficult to appropriately size the battery racks to account for the energy duration the system requires. Fortunately, more battery vendors are offering modular DC block systems that allow integrators to size the system at a more granular level; on the converter side, there are development efforts for larger systems that will also provide design flexibility for larger battery pairing.

In designing the system, it is essential to consider rack usable energy rating (how much energy can be output from a given battery) and DC-converter size. As shown in Figure 1, low converter power rating paired with high energy battery system

will yield increased inefficiency in the system, leading to lower optimization capability, while higher power converter rating will provide more optimal design considerations with increased design efficiency and design flexibility. Pairing a 2500kWh battery system on a 250kW converter is certainly not the best configuration or design (500kWh energy required for 2-hour and 1000kWh required for 4-hour systems). Evaluating optimal converter and battery system pairing is critical to system design considerations while targeting optimal levelized cost. Larger converter sizes and smaller battery unit energy rating provides more design flexibility for more optimal design factors.

Any DC/DC converter is limited by its maximum rated current, as is the case with any power conversion system. Much like a photovoltaic (PV) inverter, which is dependent on the DC

voltage condition of the PV, the DC/DC converter for the battery is limited by the maximum power that can be output. This, in turn, may be affected by temperature-based power de-rate factors that could be 10 percent or more. This requires careful project level analysis based on battery charging and discharging characteristics, as well as solar operational voltage.

While converter sizing is a microdesign consideration that needs careful study, finding DC to AC ratio, also known as Inverter Loading Ratio (ILR), is critical to optimize DC-coupled projects. DC/AC ratio is defined as the nameplate DC power of the modules versus the rated nameplate AC power of the inverter. The maximum DC power is limited by land constraints, and the maximum AC power is limited by interconnection agreements for solar power plants. Optimizing the DC-coupled solar plus energy storage is more complicated, as additional PV clipped energy that can be captured by the energy storage system needs to be

taken into consideration. An in-depth analysis of the DC cost of the system versus the value of clipped energy is needed to minimize the Levelized Cost of Energy (LCOE) of a solar-plusstorage project, while maximizing the megawatt-hours (MWh) of solargenerated electricity fed into the grid. For example, as the cost of DC systems or PV modules goes down, developers tend to choose a higher DC to AC ratio. In addition to the financial considerations above, engineers on the project need to make sure they are not exceeding the maximum short circuit of PV inverters.

Technical challenges: shortcircuit analysis

After determining the PV DC and AC sizing, a short circuit study is required to ensure that the short circuit current requirements are met. The NEC code 690.8(A) addresses these requirements. The engineer of record (EOR) must evaluate and review PV panel spec, DC/ AC ratio, number of strings per inverter, string sizing, and detailed project drawings. In many cases with the PV inverters available in the market, the DC converters are connected directly to the inverter’s internal DC busbar, so the Battery Energy Storage System (BESS) short circuit needs to be added to the overall short circuit withstanding of the power conversion system. An initial easy approach – to ensure that we are not exceeding the peak fault of the inverter –is to multiply the peak fault current rating from the battery vendor by the number of battery units in parallel, to see if this is less than the allowed fault current at the DC/AC inverter terminal. In addition to peak fault current calculation, fuse rating studies need to be performed to ensure the proper overcurrent protection of the energy storage system design.

In analyzing these design challenges for a DC-coupled solar plus storage system, an engineering and design team can find the right balance between available space for the project and the cost of the PV and battery system, to determine optimal levelized cost of energy for the solar and energy storage plant. The addition of storage to a solar project, though increasing design considerations and complexity, creates dispatchable power plants that can improve grid reliability and stability all over the world.

Virtual central distributed inverter stations

The EPEC PICS product offering now makes string inverter technology affordable for large utility scale plants. The PICS 500 (.5MW) and PICS 1000 (1MW) are “virtual central” distributed inverter stations certified for use with multiple UL 1741 string inverter brands (output voltages from 660Vac to 800Vac).

Centralized DC:DC converter

Alencon Systems LLC has launched the CUBE - its newest line-up of high power, high voltage DC:DC converters for alternative energy applications. The CUBE - (Combined Universal Buck/Boost Power Electronics) is a compact, centralized DC:DC optimizer. The CUBE is available to support both 1000V and 1500V DC:DC applications. The CUBE is available in two modalities – the CUBE-PV for solar applications and the CUBE-ES for battery energy storage applications. The CUBE offers a high level of power density achieved via a silicon carbide-based power train. The CUBE is currently patent pending with the United States Patent Office. For large scale PV plants, the CUBE-PV provides distributed energy harvesting to increase energy yield for projects using larger central inverters. By operating at higher voltage and lower current, the CUBE-PV allows for less copper to be used in the balance of the system. Additionally, the CUBE-PV allows PV plants to be “storage ready.” The CUBE-PV can also be a tool for repowering older PV arrays. For battery energy storage applications, the CUBE-ES offers a highly dense, costeffective package for integrating batteries into DC coupled solar plus storage projects. The CUBE-ES is a solution for stepping up voltage from lower voltage batteries to higher voltage power conversion systems (PCS). As a result of its high switching frequency, the CUBE provides little additional fault current contribution to a battery energy storage system.

Providing Virtual Assistance for Cable Inventory Management.

Helping customers evolve towards the 4.0 Industry, Prysmian Group presents Alesea, a new IoT innovative solution taking cable inventory management to the next level. Let us introduce you to Alesea, its components and usage in the North American market.

We have heard about the “4.0 Industry” for many years now, a fourth industrial revolution driven by digital technology which gives birth to the highly anticipated “smart factory,” fully computerized manufacturing through the Internet of Things (IoT). Alesea, Prysmian Group's latest innovation contributing to the 4.0 Industry, is our answer to the "smart factory." An IoT solution providing virtual assistance for cable inventory management through a smart device installed on cable reels, Alesea delivers a cloud-based platform that tracks reel management, data storage and processing within an intuitive web platform.

Alesea was developed in a collaboration between Prysmian Group and the Corporate Hangar, a team devoted to developing state-of-the-art solutions for multiple sectors seeking digital transformation. Equipped with a GPS tracker, environmental sensors, motion detectors and multi-network mobile communications, Alesea allows worldwide coverage. The system lets customers track realtime reel location, identify potential theft and manipulation, assess whether there has been any use and track the amount of cable remaining on a reel. Most importantly, no user installation or maintenance is required. Upon service activation, data is automatically stored on the cloud, retrieved at any time and accessed through customizable mobile and desktop platforms.

As a result, Alesea offers a comprehensive inventory management service while helping to reduce the total cost of cable management and reduce the time each reel spends empty and unused, all thanks to its improved asset usage and enhanced operating efficiency. As the device is installed on the reels during cable production, it is no longer necessary to intervene on-site resulting in optimized logistics and cable waste reduction, improved pick-up and transport of empty reels by collecting multiple reels and minimizing the environmental impact.

“Alesea transforms cable drums into smart assets, achieving a higher performance in terms of operating efficiency and sustainability,” said Maura Nespoli, VP of Sustainable Solutions at Prysmian Group North America. “We are currently already in the process of implementing and deploying Alesea devices into all our North American steel reels. This will translate to direct reductions in the industry’s carbon footprint by reducing the number of reels used and maximizing the efficiency in reels’ transportation.”

By 2030, Alesea aims to reduce CO2 emissions by 21%. Thanks to the device and the real-time data it provides, customers will reduce reels’ cycle time and improve the circularity and recycling of steel reels. Together, this will reduce the need for steel production and optimize logistics and transportation, translating into lower emissions.

Smart innovation with sustainability and the environment in mind. That’s our reel revolution.

Nel Hydrogen manufacturers Alkaline and Proton Exchange Membrane (PEM) water electrolysers, which when connected to a source of renewable energy, produce from 0.27 Nm3 to 19,400 Nm3 of Green Hydrogen per hour. Units can be grouped together into electrolyser plants for even larger production rates. Electrolysers are used to store excess energy (electricity) from renewable resources in the H2 bond. The hydrogen can then be sold to industry (converting curtailed power to cash), or burned in a turbine or run through a fuel cell to put the stored energy onto the grid during periods of low generation or peak demand. Due to their fast response times the PEM electrolysers are also used by renewable energy plants to balance the power put onto the grid.

US Offshore Wind Outlook

Energy generated by wind turbines is a sustainable resource that can produce enough electricity to power major cities around the world. Lately, the focus has shifted to offshore wind power, where large farms of wind turbines are installed in bodies of water (usually the ocean) to take advantage of higher and more consistent wind speeds. This helps to generate substantially more electricity than onshore wind turbine facilities.

Historically, the US hasn’t been that invested in offshore wind power. But that is changing as the 2021 Infrastructure Bill is making bold investments in clean energy. As of today, there are only two offshore wind projects operating in the US, one of which is a small pilot project. However, there are plans to develop many more in the coming years, both on the east and west coasts. In fact, only a few months ago we celebrated the ground breaking of South Fork Wind, a 130-megawatt (MW) wind farm off the coast of Long Island that will produce enough energy to power 70,000 homes and displace six million tonnes of carbon dioxide. South Fork Wind is expected to be in service by the end of 2023.

As the energy industry embraces offshore wind as a viable— and reliable—source of clean power, let’s look at some of the key considerations for developing these kinds of projects.

Procuring vital offshore transmission cables— and protecting them

An important consideration in the development of offshore wind is the procurement and protection of the cables needed to transmit the power into the onshore power grid.

Several factors need to be considered when selecting appropriate transmission technology and optimizing efficiency and costs. These include the distance from shore, amount of power, and ultimate development scenarios for offshore wind in the area. High voltage direct current (HVDC) technology can

transmit larger amounts of power over longer distances with lower losses, as compared to high voltage alternating current (HVAC) cables. Submarine and underground cables are required for transmitting power from the wind farms, no matter which technology is chosen.

Currently, cable manufacturers worldwide are operating at full capacity due to the high demand for power cables. The demand is not just for offshore wind farms, but also for transmission development and the integration of renewables in general. This means that procuring the cable systems for wind farms can take longer than usual. So, it’s important to engage project developers and cable manufacturers early in the process. This way both parties are aware of timelines and able to plan out the project accordingly.

Because the offshore wind cables take longer to procure, it makes them even more critical to protect. Cables can also be very costly to repair. It’s not just the price to repair the cables, but also the lost revenue from the outage. It can take months to repair or replace a damaged cable, so implementing measures to protect them is very important.

One mitigation measure for protecting cables from damage is burying them in the sea bed. This is done using either simultaneous lay and burial, or post lay burial techniques. This helps to reduce damage from anchors, fishing gear, and dredging. The specific protection measures should be evaluated during the design phase of the project.

Installing cables while protecting the environment

It’s not just about protecting the cables, but also about protecting the environment. When installing cable systems, it’s critical to mitigate impacts to the surrounding environment by reducing disruptions to the sea floor, sensitive coastal environments, and marine life. Burying cables will create a temporary disturbance of the sea bed. During the permitting process, the species and plants that live on the sea floor need to be documented, and the design and installation of the offshore wind farm must minimize impacts on the marine life. Environmental impacts must also be minimized throughout installation and design, such as any installations in high erosion areas.

Offshore wind projects must also consider avoiding sensitive habitats wherever possible, both offshore and onshore. This is where the use of horizontal directional drilling (HDD) comes into play for landing points and onshore installation. HDD helps to avoid sensitive shoreline resources and habitats by drilling below them. That way, when the cables reach the shoreline, they won’t just be running up and along a beach; they’ll be buried under the shoreline to ensure no disruption to the surrounding environment.

Cable installation must also account for other ocean uses such as fishing interests, sand borrow areas, artificial reefs, and navigation channels. Burial must be at sufficient depth in or around these areas to mitigate potential impacts.

As you can see, a lot of consideration goes into how cable systems are designed. Protecting the cables and protecting the environment must go hand-in-hand.

Barriers facing the offshore wind industry

While we are witnessing the development of more offshore wind projects in the US, we are still seeing several barriers facing the industry. An expensive price tag is not the only challenge that offshore wind projects face. Apart from the harsh offshore conditions that require equipment designed to withstand extreme weather, another challenge is connecting the power into the onshore grid. Foresight, good planning, integrated engineering/


environmental evaluation, and efficient design are all critical success factors. Permitting and environmental hurdles to offshore wind in the US also exist. In order for offshore wind projects to obtain permitting approvals, rigorous environmental and engineering studies need to be done. These studies must demonstrate that the selected design, route, and installation methods minimize and mitigate adverse environmental impacts. The intermittent nature of offshore wind power—not unlike most renewables such as solar power—is also often brought up as a concern. Critics question the effects that offshore wind has on the grid, as well as the ability to regularly meet our fluctuating electricity demands. In reality, offshore wind and solar power can work together to help with these fluctuations.

The integration of renewable power generation, which relies on electronics to interface with the power grid, is changing the nature of the electrical grid. Transmission planners, operators, and developers need to consider these changes and upgrade the transmission system accordingly. This is critical to maintaining the reliability of the power system, given the significant increase of renewables that is expected in the future.

As experience grows and new technologies come into play, we will learn more about balancing the grid, and begin to focus on the numerous benefits offshore wind power can provide.

A greener future with offshore wind

Although there are several challenges to these bold projects, investment in offshore wind energy is still very important. Why? Because offshore wind can help guide us through the energy transition, and lead us to a cleaner energy future. Exciting developments we are seeing in the industry include:

• Further development of HVDC systems using equipment and control systems from multiple vendors, making multi-terminal HVDC systems and HVDC grids more viable and more economic.

• Improvements in manufacturing technology and capacity, as well as cable installation vessel equipment, to support the development of more projects.

• The extension of the onshore grid to create integrated points of interconnection at wind energy areas. This will help reduce connection costs and improve the overall reliability of offshore wind.

• The development of new cable designs using improved insulating compounds that support higher voltages and currents. This will increase the amount of power that can be exported on a cable circuit and lead to cost efficiencies.

• The increased use of HVDC systems to facilitate larger wind farms located farther from the shore.

• The development of higher voltage dynamic cables to support the growth of floating offshore wind in deeper waters.

• Technology advances in wind turbine designs leading to each individual wind turbine being able to generate more power (the current maximum is 15 MW per turbine).

As we head forward, it will be interesting to watch the offshore wind industry grow and evolve in the US. And, if the US is truly committed to reaching 30 gigawatts of offshore wind power by 2030, we should see many more wind turbines being installed offshore in the coming years.

Offshore Forecasting

Offshore wind is taking off in the U.S. Declining offshore wind costs, rising demand for renewable energy, and increasing government actions have accelerated the evolution of the U.S. offshore wind sector. According to the Office of Energy Efficiency and Renewable Energy, the U.S. offshore wind energy pipeline increased by 24 percent from 2019 to 2020. Moreover, the U.S. has set its sights on 30 GW of offshore wind capacity by 2030.

As U.S. wind developers and operators increasingly explore offshore locations, it is essential to understand the critical role the weather plays in the operations and maintenance of offshore wind farms. Not only does weather determine the output from the turbines, it also governs when you can safely access offshore locations for installation and maintenance.

Strong winds and high waves may limit the accessibility of offshore locations, causing difficulties when loading, transporting, and installing wind turbines during construction. Lightning and thunderstorms may also threaten the safety of technicians during installation and maintenance work.

Offshore weather can be extreme, and conditions change rapidly. Throughout all phases of developing and operating an offshore wind farm, understanding the on-site weather conditions is key.

Accurate Weather Forecasts for Efficient Offshore Development

Offshore wind projects always involve a tradeoff between the cost of equipment, logistics setup, and weather downtime. With these three factors in place, weather becomes the limiting factor for offshore operations. Wind developers and operators rely on location- and industryspecific weather forecasts for better installation and maintenance scheduling, and increased safety of every crew member when at sea. For example, during the construction of one of the first offshore wind projects in the U.S. – the Coastal Virginia Offshore Wind project

– accurate weather forecasts were used extensively to give different suppliers and stakeholders the information they needed to work efficiently and safely.

In development projects of this scale, local weather expertise can often be overlooked, leading to project delays - even safety incidents as logistics setups are pushed to the limit. Experienced offshore wind developers know the pitfalls; one European-based offshore wind installation contractor leveraged accurate weather forecasting to define weather windows for installing components like wind turbine blades during the pre-assembly and installation phases. Thanks to precise weather forecasts, the developer could plan ahead to have a blade rigged in time to take advantage of weather windows that often were as brief as two hours.

Safer Far-shore Operations with Weather Intelligence

In a remote far-shore location in the North Sea, wave heights can reach 10 meters and wind speeds can top 24 m/s. Yet, several wind turbines power nearly 400,000 homes every year with clean and sustainable energy. Each turbine requires regular maintenance to continuously supply this energy to the grid. As access and work on these turbines must be carefully planned, weather intelligence dictates scheduling logistics and safety.

Technicians access the turbines by service operation vessel (SOV) or helicopter, according to specific safety thresholds. For the SOV, the most important threshold involves wave height; the maximum safe limit is two meters. In fact, when landing, just 20 centimeters can make a big difference.

Site-specific and timely weather forecasts help to simplify planning. The operations team uses daily forecasts every morning to decide how many teams to send out, and when they need to bring them back to stay within their thresholds. In five years, they have never had a situation where they had to leave anyone on the turbine - everyone has been delivered safely back on the vessel.

Advanced weather forecasting is also an essential tool for the service teams when they are out on a turbine. Certain tasks require specific weather thresholds. When onsite, the technicians can check these thresholds and plan a job accordingly. Craning up a turbine from the outside, for example, needs calm weather.

Advanced weather intelligence keeps technicians safe, both physically and mentally.

The Importance of Understanding the Weather

The development of offshore wind in the U.S. today closely parallels the development of offshore wind in Europe only a few decades ago. Both markets have adopted ecofriendly energy policies in response to climate change pressures and public interest. However, while recent offshore wind projects in Europe compete with other energy sources without the need for government subsidies, operational offshore wind projects in the U.S. are still small demonstrations meant to showcase the industry’s potential.

As offshore wind power catches on in the U.S., developers and operators can learn valuable lessons from their European counterparts – especially the importance of understanding the weather during the planning, construction, and operation phases. When working offshore, good weather is a precious resource. Accurate forecasts ensure offshore wind developers and operators are ready to go as soon as a weather window opens - improving efficiency, ensuring the turbines are well-maintained, and keeping operating costs at a minimum.

Detect Lightning Damage Early

Incidences of lightning strikes globally are on the rise, just another of the many consequences of climate change. It’s been estimated that countries like the US could see a 50 percent increase in the number of strikes by the end of the century. When it comes to wind energy, lightning is a huge risk factor in that it often causes damage to turbine blades. Plus, its unpredictable nature makes it a silent and ever-present threat. Insurers are dealt a tricky conundrum – if the blade already had latent defects, whose responsibility is it to pay for these acts of God? And yet, how can the damage be proved to have resulted from a strike without accurate monitoring of the turbine?

A wind operator in Brazil stated that, at the end of the lightning season, 35 percent of their wind turbine blades had experienced some lightning damage. It’s a perfect storm – wind turbines attract lightning because of their passage through air, and their structure is increasingly being designed to be taller, thus making them more vulnerable. Couple this with global warming increasing the likelihood of such incidents, and it is crucial that strategies are put in place to minimize the downtime and repair costs when lightning strikes.

The majority of blades do have receptors built in that are designed to attract lightning, which is then sent down through the conductor, all the way through the tower, and into the earth. Unfortunately, this system is not fool-proof, partly due to developments in blade design, such as increased length of blades, as well as general wear and tear of blades and lightning protection systems. In other words, damage still can occur. Unfortunately, the most troublesome aspect of lightning is its unpredictability. While there is nothing that can be done to control such adverse weather events, repairing damage caused in a timely manner can mitigate damage. But how does an operator know that damage has even occurred, particularly if the turbines are in remote sites, on and offshore? There are currently a number of ways sites can be monitored, but each has pros and cons.

Drone and robot inspection

Technology has come a long way, and the use of drones and robots is becoming increasingly more commonplace in wind turbine inspection. These advances in technology afford operators with a visual record of the state of the blade; they can be deployed on infrequent intervals, allowing for an accurate understanding of changes over time. But operators will not be able to implement the technology on a daily basis. This means if anything should change soon after inspection, there will be zero visibility, and it could be months before damage is picked up – leaving you open to more expensive repairs or risk of structural failure.

Technician inspection via Rope Access, Ground Cameras, and Platforms

While technology can be your friend, the alternative is to have damage inspected by a skilled technician. However, this involves costly time, as well as challenges finding a skilled technician or engineer, and additional problems associated with accessing turbines in remote locations or offshore.

Rope access provides an alternative to truck-mounted platforms and other blade access platforms. These provide advantages in that they don’t require specialist mechanical lifting equipment. However, they can’t be carried out frequently, due to obvious resourcing constraints.

Consider that a lightning strike occurs and damages a blade in a site that just recently had its regular maintenance check in person. You could be waiting up to 12 or 24 months before that damage is discovered. Meanwhile, any damage worsens and escalates over time, leading to the failure of the entire blade. In worst case scenarios, the entire tower is destroyed. There are reported instances where a blade (weighing many tons) has separated from a wind turbine due to exposure to a lightning strike. Whilst this is a rare occurrence, it doesn’t take much imagination to consider the repercussions, let alone the potential replacement cost (a tower replacement can be in the order of $7 million). Aside from this ‘worst case scenario’, incremental and immediate damage can be costly if not addressed immediately.

Continuous monitoring

Monitoring on a regular basis means notification of damage when it occurs. Early detection is vital to minimize long term harm that will inevitably intensify if damage is not addressed in a timely manner. It will have wider impacts, and, crucially, can be extremely dangerous.

Lightning damage to a blade was identified on two of the 48 turbines monitored for an operator in North America. The lightning tracking system showed there was a +61kA strike on one of those turbines. This early detection ensured a technician (with a groundbased camera, drone, or rope access) could attend to the site immediately to assess the damage. Without continuous monitoring, it could have been months before it was discovered, during a manual inspection by a technician. By then, however, damage may have escalated, forcing repair costs significantly higher, and making blade replacement necessary, or – in the worst case – requiring complete replacement and/or tower failure. Regardless of the monetary impact, no operator or OEM wants to leave themselves vulnerable to litigation or skyrocketing insurance costs. It’s a no brainer to invest in monitoring equipment that protects an owner/operator’s biggest asset – the wind turbine blade. Without it, you may face damages that can have devastating and potentially worsening consequences.

The US set an ambitious climate target of reaching net-zero carbon emissions by 2050. To do this, renewable energy will have to be ramped up. The 30 gigawatts of offshore wind being developed in the next eight years shows that the will is there. But with this pledge comes myriad issues; ensuring the effective operations of renewable energy providers is paramount in order to meet these targets. Rather than waiting for the impact of weather incidents to have irreparable consequences, continuous monitoring is one option that helps minimize downtime, maximize output, and boost productivity.

This unique combined experience led to the formation of Ping, when a wind farm operator challenged Matthew to make a device that could hear blade damage just like technicians can hear on site. Matthew has a bachelor’s degree in Engineering (first class honors) and a master’s degree in Engineering Science (Acoustics).

As the Wind Industry matures, and OEMs face steep pricedriven market challenges, the notion of traditional risk models are changing. OEM competence and the capability to continue to adequately serve the market is questionable. Even with OEM warranty coverage, there are contract carve-outs for parts like blade wear-and-tear, caps on component failure rates, liability limits, and shortages that give reason for additional business considerations to owners.

The Wind OEM is primarily the designer and not the direct manufacturer; OEM platforms are less vertically integrated, with fewer IP barriers. Because OEMs depend more on sub-suppliers, the US Wind Industry supplier base has matured, and can provide services directly to owners.

Wind OEMs also heavily outsource for service support in the market, which drives owners to seek support directly from sources or self-perform. The recent entrance of institutional investors into the services segment created consolidation of dozens of smaller suppliers into fewer large suppliers. These consolidated suppliers can tout an ‘all of the above’ offering. Where OEM support is waning, limited, or where economics and risk otherwise make more sense, owners can reasonably find quite capable non-OEM options.

In turn, the US Wind Industry employs a combination of operating philosophies, with perhaps only ~30 percent of the market self-performing some portion of their assets. The remaining work is contracted to suppliers.

Philosophies drive strategy

A procurement philosophy depends on the operating approach. Some companies will use OEM channels to operate as a primary supplier. OEM operating strategy, or simply a small operating footprint, may work without a procurement team. Other

companies that grow away from OEM dependence, or have a larger operating footprint, have more complex demands and require procurement strategies.

Traditionally low-risk and externally insured companies may be very reliant on the OEM for longer term warranty and services after the initial equipment purchase. This stems from investor models relying on the OEM to hedge risk. Such owners mitigate risks to the model with independent audits, and can use a limited management model to ensure the OEMs are delivering on obligations.

On the other hand, a traditionally higher-risk and often internally insured model is less reliant on the OEM for service and warranty after the initial equipment purchase. Such self-performers take on the risk internally with more robust teams for engineering, operations, analytics, and supply chain. In companies that are less reliant on the OEM as a supplier, a strong procurement arm is vital.

Value management

Procurement departments are included in business models when supplier management can be used to leverage value with multiple competitor suppliers. When employed, procurement teams are expected to drive the commercial activity and contracts involving company expenditures. Procurement teams are expected to attract and maintain supplier relationships when external resources are needed for special skillsets, preferred economics, or resource availability.

In short, procurement buys from and manages suppliers, but strong

and experienced business acumen is required. Procurement functions at a crossroads with overlapping competencies that include EHS & Quality, Engineering & Operations, IT, Asset Management, Legal, and Compliance. They must be able to structure and standardize tools for multiple disciplinary scopes of work. Procurement leaders are trained to counternegotiate sales ninjas and create a level playing field to fairly and economically evaluate supplier offerings.

Handshakes and spreadsheets

The constrained labor market is ominous because it creates an environment which can introduce inexperienced workers, shortcuts, and mistakes that implicate quality and safe work. The mature procurement team knows that many qualities, not price alone, must be accounted for to achieve quality and safe work. While the mature supplier knows how important and challenging it is to build and maintain culture, not just provide warm bodies.

Supplier partnerships always start with a handshake evaluation of relationships and values. The leaders and the network tenure ensure champions are in place to work through future business issues together.

The supplier qualification process is subsequently orchestrated with a variety of tools to try to balance high efficiency with ‘doing the right thing’ – ideally both! Running the numbers through a procurement qualification process can seem tedious to all parties, but it is an inevitable step. And it’s critical to conduct a careful review of supplier metrics to seek quality and deep understanding of expectations, not merely a superficial spreadsheet comparison, especially with the growing trend to outsource suppler qualification services.

Hasty checklist qualification methods can overlook other supplier operating values, leading to a revolving-supplier-door limiting the ability for parties to grow and support each other

long-term. Such superficial checklist methods can also drive supplier system-gaming like price cutting and rubber stamping. For instance, if a new supplier does not have a safety record yet, they are unable to provide a history of TRIR and EMR , and unlikely to be qualified. Does this supplier get instantly rejected, conceal the record by partnering with another company, or explain the situation through a waiver process for special management considerations?

Find and tell the culture-story of the supplier as part of the screening process. A culture-story should be evidenced with examples such as proof of background checks, sample resumes of key technicians, and references from other customers. At a minimum, evaluate how desired behaviors are driven in the business (i.e., use of leading indicators for safe work, rework tracking for quality assurance). Together, the procurement and supplier relationship can catalyze the right working culture by setting strong expectations up front.

Despite fantastic supplier competition in the Wind services market, there is still a ‘perfect demand-storm’ of labor supply shortages, persistent equipment reliability trends, and ever-aging fleets. Supplier management is now more challenging than ever, and it puts procurement ‘front-and-center’ to support operating services’ business needs.

Preventive blade maintenance with lightning current monitoring

The Lightning Monitoring System (LMS) from Phoenix Contact detects and analyzes in real time the magnitude, duration, number, and other parameters of surge current events caused by lightning strikes. Detailed lightning analysis can be an effective input to asset management systems to optimize the inspection intervals for wind turbine blades, as well as appraise damage requiring immediate attention. This can result in performance improvements by reducing turbine downtime and increasing availability. This has important implications as wind turbines become larger and are located in more access remote areas such as offshore applications.

Compliance with NERC = Higher Margins of Reliability

Obviously, the NERC Reliability Standards (Standards) were developed with the intent of improving reliability of the Bulk Electric System (BES), but how does that directly translate to actual improved performance and reliability of the Facilities that make up the BES? As a Senior Auditor at NERC, I fielded this question multiple times. There is no easy answer. True, the intent of the Standards is to increase reliability. While there is no data to support the idea that the Standards are responsible for increased reliability of the BES, they do provide a rigid set of requirements that, if complied with correctly, absolute increase reliability. At the very least, they decrease the likelihood of diminished reliability of the BES. In addition to this very valuable benefit of compliance with the Standards, the motivation for many to comply with them also includes hedging against potential findings of noncompliance, and the dreaded fines that may be associated with instances of violations. With that being said, let’s take a look at some of the Standards that seem to be violated more than others.

Most violated Standards (and the associated risks)

Last year, CIP-007, CIP-010, and CIP-005 were the three of the most violated Standards, which begs the question, why are we, as an industry, having so many issues with these Standards? The easy answer is we are part of an industry that, for decades, has been focused on one mission - to generate, transmit, and distribute electricity. The added expertise needed for cyber and physical security isn’t something that has always been a fixture in our industry. The violation numbers suggest that more work is needed with compliance efforts for CIP Standards. What’s the risk? Well, there’s the risk of unwanted intrusions into our Facilities, our networks, our SCADA or EMS systems, etc. There’s no shortage of threat actors who would seize an opportunity to cause negative impacts on the BES; CIP Standards are designed to make it very difficult for that to happen. The CIP Standards have undergone more overall versions than the Operations and Planning Standards, signaling the fact that these requirements are changing to try and keep up with the ever-present cyber and physical threats. In simplistic terms, bad actors need only be successful once, while we must be successful every time there’s an attempted breach of security. The extent of damage could quickly move beyond one Facility to impact the entire system, which is why these Standards must be at the forefront of everyone’s compliance efforts.

In addition to the CIP Standards mentioned above, the list of O&P Standards that were violated most in 2021 include PRC-005, FAC-003, EOP-008, and PER-003. These particular Standards address protection system and relay maintenance, vegetation management, loss of control center functionality, and operating personnel credentials. These Standards and their associated requirements deal with very tangible issues that we must master in order to maintain a reliable BES. It’s not too difficult to understand how maintaining lines and relays, ensuring the control center is functional, and training operations personnel are essential to maintaining a functioning, reliable system.

The real question is why are these Standards finding their way on the list? Many times, there are missed deadlines for certain maintenance activities (such as battery testing in a substation

control house, or not keeping accurate training records). There are also occasions where it is found that a registered entity has incorrect relay settings, or there has been no inspection or maintenance of transmission lines, which can lead to devastating and expensive events for the local system – and potentially for the BES. As any good statistician will say, an increase in small, seemingly insignificant issues will eventually result in larger and more intense problems, should they go unchecked. Many of these violations were found during an audit or Spot Check. This leads me to the next point: catching these vulnerabilities or violations before they become a larger problem.

It is much better to identify these issues through a robust internal controls and program improvement effort that leads to self-reporting violations, rather than to be caught unaware during an audit. Yet, even in the case of uncovering a violation during an audit, there are mitigation efforts that are triggered to ensure the issue is properly resolved, and steps that are taken to ensure the issue will not continue in the future. This view on audits, although anxiety provoking, is a good way to correct issues that have the potential to wreak havoc on the BES. It is always better to identify and correct any potential issues through selfreporting, than to have an Auditor find the instance of non-compliance. On the flip side, the benefits of identifying these possible pitfalls far outweigh the approach of doing the bare minimum and hoping the Audit team doesn’t find any violations.

Building a culture of compliance

When taking a deep dive into a NERC compliance program, we inadvertently take a long look at the operations and planning departments and processes, leading to more reliable and compliant operations. By conducting an analysis to ensure any

gaps in compliance are identified, an entity can greatly reduce the potential for greater fines, while increasing reliability. If, while already working to remedy the issue and develop a mitigation plan, an entity selfreports a violation, NERC and the Regional Entities view this as an indicator of a strong compliance program and a healthy culture of compliance.

Compliance staff partnerships with business units

There once was a common view of compliance personnel as people who make a job more difficult by enforcing regulatory requirements, while business units are just trying to do their jobs. Over the past decade or so, that paradigm has shifted in many entities, leading to a better partnership between operations and planning personnel and the compliance staff. Compliance should be viewed as a mechanism by which we improve processes and programs, becoming more efficient and reliable as a result. At many ISOs, transmission entities, and other utilities, the compliance department is now comprised of former System Operators, Analysts, and Engineers from the business units, which leads to a better understanding of how the work is being completed and how that complies (or doesn’t quite comply) with the Standards. By cultivating this partnership between ops and planning staff and compliance personnel, and achieving buy-in from all involved, there is a greater likelihood that mistakes will be caught and corrected, leading to an increase in reliability.

A Good Culture of Compliance is a Great Compliment to Existing Operations and Planning Departments

In our usual operations and planning duties, it is important to take the occasion to remember why we’re doing what we do. In order to keep supply and demand properly balanced at 60Hz, ensure all load is served, and maintain the systems, equipment, and facilities that make this possible, we need a framework of requirements to ensure there are no gaps in reliable operations. The NERC Reliability Standards are developed to do just that. By using industry volunteers to draft the Standards, we have a voice in the NERC process. This means that, using our best people to engage in the compliance process at the NERC and RE levels, we can help ensure that the Standards are being written well and will accurately address the issue the Standard is trying to resolve. In closing, it is very important that our industry stay on top of developments at NERC, including project meetings, steering committees, upcoming standards, and engage our best people in the compliance processes. By doing so, we will be better represented, and the reliability of the BES will remain high in the years to come.

Make Your Wind Turbine Last Longer

How foundation and tower monitoring can extend the life of a wind turbine

Awell-maintained car will run for longer than a hard-driven, neglected one – and cost less over its life. Wind turbines are much the same. However, wind farms are multimillion-dollar energy generation assets, so keeping them running for longer means significant additional revenue for owners.

That’s why life extension is becoming more and more crucial as wind owners and operators seek to hedge against energy market uncertainty by extracting additional value from their existing portfolios. This requires a continuous investment into their turbines and fleets. With a best practice life extension strategy in place, operators can see useful asset life increased by up to 25 percent – with up to 12 percent higher sale prices if assets change hands.

Wind operators have an opportunity to transform their life extension strategies due to advances in monitoring technology. Although drivetrain monitoring remains a key component of profitable life extension strategies, predictive maintenance approaches now include all types of data. Data on pitch bearings, blades, rotors, as well as foundations and towers are coming into play, helping operators make the best possible decisions on component replacements and repowering work.

Life extension and repowering

Owners and operators have a strong incentive to extend asset life. A turbine pays for itself in the first 10-15 years of its life. Selling electricity produced after this, once O&M costs are considered, represents pure profit. This means that the largest factor affecting the value of a project is whether life can be extended, as the transformation of financial modeling from running assets for 25 years versus 20 years is significant.

There is another factor involved in intelligent life extension – reducing waste. Recently, the wind sector has begun to target carbon emissions in its supply chain more proactively. A move to a circular economy is within reach due to a better understanding of wind turbine technology and better materials. However, data on the remaining useful life of components is necessary to establish which parts can be refurbished, which should be replaced, and which can be left.

Historically, accurate and cost-effective monitoring has been restricted to the drivetrain, tackling the biggest cost failures first but neglecting crucial components such as towers, blades, and foundations. New advances in data analysis have led to a leap forward for operators, as they can now use their existing drivetrain vibration monitoring systems across the turbine.

This is particularly crucial during partial repowering, where larger rotors and generators are fitted to the existing towers to upgrade the capacity of a site. Understanding what is technically feasible during this process ensures that operators can push the boundaries without compromising safety.

The tower and foundation challenge

Partial repowering and life extension have given rise to towers and foundations with a potential service-life exceeding 40 years. Replacing this infrastructure is rarely economical, so wind farm operators need reliable data on degradation.

In many cases, lenders or independent engineers will require regular foundation monitoring for life extension beyond the theoretical design life of the wind turbine.

The evidence shows, however, that many foundations can perform far beyond their theoretical life, and can do so safely provided the data indicates structural integrity.

The current trend toward short-term subset monitoring may fail to capture a clear picture of foundation integrity, due to natural variation that can be more significant than that caused by damage. Additionally, with many foundations, damage only shows under higher load levels that aren’t captured by short-term monitoring campaigns.

Predicting the outlier foundations with low strength or high loads is error-prone, and can result in damage going undetected until serious incidents occur, such as collapse.

Unlocking the full potential of drivetrain CMS

MEMS accelerometers, used in leading

Condition Monitoring Systems, are extremely adept at monitoring low frequencies, such as structural frequencies for wind turbines. Lowfrequency capable CMS can deepen operators’ understanding of foundation health. These CMS are often already installed on projects, and, if not, the installation costs fall well below that of periodic foundation testing and inspections.

Early detection and clear decision criteria are vital when dealing with foundations. Solid, quantitative results allow operators to set decision criteria confidently, and projecting future conditions permits proactive action. Predicting developments in turbine health is essential to allow time to design possible foundation retrofits, as well as construction contracting and implementation, without incurring significant project downtime, or running turbines that might collapse.

With accurate foundation data, asset owners can take a smart approach to remedial work. Foundation strengthening is costly, but monitoring provides insight on foundation health to asset owners, who can defer strengthening work and implement targeted retrofits strategically.

A solid foundation for increasing wind efficiency

Wind energy is set to play a leading role in the energy transition. No MWh can be left on the table –ensuring that assets already installed can generate clean energy for longer is the fastest way to boost and maintain renewable capacity. Operators have the opportunity to use the latest technology to gain a holistic picture of turbine health, going beyond the drivetrain to inform better, more strategic decision-making, and, ultimately, longer turbine lifespans.

Can Vibrations be Good for Business?

How much does condition monitoring save the typical wind farm?

This question was put to me during a recent conference on innovations in the wind industry. The question relates to the financial benefits of vibration analysis, otherwise known as the cornerstone of condition monitoring, compared with SCADA monitoring. As an engineer, I am well used to explaining the technical advantages of vibration technologies. But when asked to provide a cold, hard figure, I had to hesitate.

Not because I didn’t have an answer. But because it is actually a broader question that relates to a wide range of additional monitoring techniques. The application of condition monitoring must be expected to bring a return on investment in the short term. Otherwise, why apply it? But exactly how much ROI can a wind farm expect?

I was reminded of a study I conducted for a major European energy provider about ten years ago. I can’t go too deeply into the details, but I can discuss the methodology, and use published reliability datasets and my own industry knowledge to illustrate it. The method actually pre-dates, and was the basis for the flow chart in ISO 16079-21 related to the drivetrain monitoring of wind turbines; but the idea was based on the more general ISO173592.

According to most condition monitoring equipment suppliers, there are always specific, quotable examples of enormous savings delivered thanks to the successful early identification of a fault. But this does not paint a full picture. Not every installation will suffer from such costly failure mechanisms, and it is still possible that a particular fault will not be detected in time.

My method, therefore, surveyed a range of failures. For each individual failure, it identified the likelihood of that failure occurring on a given turbine, coupled with the probability of its detection by a particular condition monitoring technology.

The most challenging aspect was collecting a set of representative failure modes, and then assigning probabilities to these failures. Costs were then applied to these failure modes, as well as revised costs assuming that condition monitoring recommendations are implemented. Cost estimates included not only repair and replacement of parts, but also the cost of logistics and lost power generation.

In itself, the process did not differentiate between different monitoring types, so monitoring technology was additionally noted. Where multiple monitoring technologies were deployed, the probability of failure detection increased for some failure modes, but the initial and annual cost of monitoring also increased. Some external studies3,4 have gone as far as to conduct a detailed analysis about which technique makes the most difference.

But in this study, we calculated savings for two offshore wind farms (based on 2012 pricing), and two sets of published reliability data from the Reliawind5 consortium. Unfortunately, as this was an internal study, I cannot share specific values, although the published data is available from the WMEP database. I can also highlight the typical patterns of identified savings.

The results

We identified savings of over 250,000€ (around 251,000USD) per windfarm, per annum, in every case where a variety of monitoring techniques were applied.

It should be noted that the two specific wind farm cases predicted lower savings than the amalgamated cases from the external datasets, probably due to the newer turbines deployed on these farms, or possibly due to incomplete failure reporting in the datasets. Interestingly, the two offshore wind farms with turbines from different manufacturers foresaw savings in very different areas, even though the resulting figures were quite similar.

As part of the study, we found that several monitoring packages overlapped when it came to the type of failures they claimed to detect, with the exception of SCADA data analysis, which operates in different areas.

Monitoring techniques applied to the drivetrain (principally vibration analysis, acoustic

emissions, and oil analysis) all detect similar gearbox and drivetrain failures. Any increased savings from the application of two of these techniques is marginal compared to only one. There is a slight increase in detection probability and lead time, but no additional failure mechanisms are revealed. Of these techniques, vibration analysis delivers the widest range of failure detection, and can also be implemented for structural health monitoring.

SCADA analysis is more likely to detect failures such as blocked coolers, electrical, and control problems, as well as small efficiency losses, complementing the other techniques. Typically, the individual costs of failures detected by SCADA data analysis are low, but they occur relatively often, whereas the more significant failures detected by vibration analysis are very expensive, but less likely to occur.

The analysis of SCADA data accounted for around 20 percent of the overall savings, and improved detection rates in other areas by around 5-10 percent. Vibration analysis accounted for up to 70 percent of the overall savings, with the remainder made up of improvements in detection probability through other methods such as oil analysis.

So, when it comes down to it, vibration analysis really does generate the lion’s share of savings in a comparison between condition monitoring and SCADA analysis – although SCADA data is definitely beneficial in its own right because it detects different faults, and should therefore be used in addition to condition monitoring to access the full potential savings.

Since the study, wind turbine designs have improved significantly, but the cost of condition monitoring installations are also much lower. Taken together, I estimate little impact on the overall annual savings provided by a CMS system over the past decade, although recent market pressures are likely to have significantly increased potential savings from vibration analysis and condition monitoring.

But back to the original question about the actual savings. How did I respond?

“It depends”, was on the tip of my tongue, but based on this study and my confidence in the findings and capabilities of a modern CMS system, I could confidently reply: “At least a quarter of a million Euros per wind farm per year.” And that’s good news for everyone.

GIS Speeds Up Site Selection

Finding suitable land is a familiar bottleneck for developers of renewable energy projects. Besides the usual considerations for industrial land projects — zoning, environmental issues, topography, wetlands — renewable energy installations need to be close to electrical grid substations and to electrical lines with the right voltage rating and capacity to take on more power. These sites may need to be hundreds of acres in size. They also need to be owned by someone who's open to entertaining proposals — too many projects get scotched halfway through by owners who were never likely to cooperate in the first place.

And so, one of the developer's first big tasks is to winnow down the list of potential site candidates by gathering information such as ownership and ownership interest, proximity to electrical grid infrastructure, and other requirements. The traditional method is to hire consultants who (hopefully) have strong local relationships, knock on doors, and amass a great volume of backand-forth email, text, and phone communications. All of this gets fed into an unwieldy spreadsheet.

This scenario begs for the kinds of technological solutions we've grown accustomed to in other industries. And they're starting to arrive. When seeking a partner for a renewable energy installation, developers shouldn't hesitate to ask their engineering firms what kind of technology a firm has on hand to give the project an edge.

GIS — an obvious application for land-based projects such as these — offers promising productivity improvements. Slick mobile, GIS-based software brings disparate bits of information together in one easy-to-see dashboard — much easier to review than a spreadsheet. Having everything in one spot, and multiple team members connected to it, allows you to short-circuit what previously had been lengthy step-by-step processes. Tasks that had been done one after another now can be done in parallel. Where before you may have hired a consultant, then a land acquisition company, then an engineer (and then a person to study everything done so far), now you can get everyone involved earlier to get results more quickly.

Streamlining all these tasks and activities typically cuts site selection time by half.

With a team all using such mobile-enabled software, they can enter very specific information about parcels that are candidates for a project. GIS-based systems can be used in such a way that a developer, before ever talking to any owners, first pares down the best site candidates from among hundreds identified. This means that reaching out to owners will stand a greater chance of success, when compared to the scattershot approach so often used.

Unlike a spreadsheet, GIS allows Google Maps-like functionality but, in this case, customized to display land by parcel and with information about the parcels. If you're looking for sites near a substation, this is the way to do it. Engineers and technicians in the field can then go out and gather more information to enter into the mobile app. Only when the best sites have risen to the top does your team reach out to have conversations with owners.

As team members gather more details about the property, including specifics from conversations with owners, they enter these details into the system. When users select a given parcel, they can see these details, right down to the person who entered them and at what time, as well as photos and video if desired.

Say a company is looking to develop a wind farm over a large area, such as an entire state, and is under competitive pressure to bring it to market quickly. Having the ability to narrow down the list of potential candidates from hundreds of thousands of sites, down to dozens or hundreds, represents a powerful competitive advantage. The system draws a clearer and clearer picture of real, pragmatic possibilities. In this way, the developer does not waste time chasing down parcels that were never meant to be. For those parcels that rise to the top of the list, important information-gathering work happens faster. The jumble of email, text, and phone messages is gone. Instead, everything is automatically in one place. This can be shared with the client directly, and even the client's investors and other outside parties who want to see status and progress updates.

One of the easily overlooked benefits of systems such as these comes after these early needs are met. The system built and data gathered for the project isn't tossed away at the end of this first step; it can be further built upon during the construction phase, and then once operations get underway. A good system at the start begets a better and longer-term system.

This level of clarity also serves you well for another hold-yourbreath moment: seeking approval from the regional independent system operator (ISO). ISOs approve the all-important interconnection agreements that allow energy projects to feed power into the grid. If you come well prepared with information on how your power generation will impact the capacity on a given line, that is all the better in the eyes of the ISO that operates the grid relevant to your project. If the ISO is looking at a handful of competing proposals, and yours offers the utmost clarity, that certainly bodes well for your project.

Seek partners who are ready to bring you the latest technology. They just may have the competitive edge you need to make your renewable energy project a reality.

Gauging the Wind

Floating lidar and new wind energy frontiers

Renewable energy sources are a vital component in ensuring a sustainable future. Although we’ve understood the value of energy derived from natural sources for years, costs have traditionally made it difficult to rely on these resources. However, technological advancements have made it more cost-effective to leverage renewable energy like wind power, increasing its ubiquity by huge margins. In fact, according to the International Renewable Energy Agency, global installed wind generation capacity has increased by a factor of 75 in the last two decades. As we expand this capacity, we can continue to explore offshore wind applications, which are often rich in previously inaccessible resources.

Wind resource assessment (WRA) is a vital part of planning and building offshore wind farms efficiently, as it provides valuable insights into wind conditions, and shows what kind of equipment is needed in what locations. Fortunately, various technologies can offer reliable data for an offshore WRA, even in the deepest waters.

The Importance of Wind Resource Assessment

The wind energy sector is constantly evolving. Offshore wind farms are not only being built in deeper water farther from shore, but also on a larger scale with bigger turbines. As the wind energy industry strives to harness abundant, more robust, and more consistent offshore wind resources, floating wind turbines are also increasing in popularity for offshore measurement campaigns. All of these advancements incur higher costs, meaning the stakes are higher than ever before when choosing a location and proper equipment. Without reliable data, money and time can be wasted on inefficient projects. Therefore, a WRA must be appropriately conducted to validate any offshore wind energy project.

To get the most out of a WRA, one must employ a solution that reliably provides a thorough picture of wind conditions. Since the offshore environment presents unique challenges — which are exacerbated in environments where floating turbines could be deployed — solutions specific to this application are crucial. After all, these challenging offshore environments may have the most abundant wind resources.

The New Standard

Increasingly, lidar is becoming standard for wind measurement. Vertical profiling lidar is perfect for providing direct wind assessment, and reduces measurement uncertainty to improve project bankability. Vertical profiling lidar is a lower-cost option that can make a WRA more accessible. Scanning lidar can provide an even more complete look at real-time wind data by providing 3D spatial mapping of the wind field affecting multiple potential turbines. Employing dual scanning lidar can also increase the area that can be mapped, and the accuracy and efficiency of offshore wind assessments in areas with difficult-to-assess wind phenomena. Lidar technology is increasingly used worldwide to validate new wind farm projects.

Fixed position lidars have many benefits, but their range is such that they aren’t ideal for floating wind turbine installations, as these must take place far from shorelines. Consequently, wind farm project owners and operators will require innovative technologies to properly assess and characterize available wind resources.

That’s where floating lidar comes in.

The Floating Frontier

Floating lidar is a unique option that enables operators to deploy marinized vertical scanning lidar on buoys that support the system, as well as lighthouses, substations, and vessels, allowing for WRA in even the deepest water. Providing a rugged, versatile option specifically designed to float, floating lidar is a crucial tool where there may be no available fixed platforms. With robust casing that ensures the movement of the waves does not create errors in the data, most floating lidar instruments deliver reliable insights vital to validating the time and expense of a deep water or floating wind turbine installation.

Floating lidar was recently used on a site in Australia for precisely this purpose. Because the proposed wind farm site was distant from the shore and in very deep water, floating lidar was the perfect solution to the challenge of conducting a WRA. Deployed for two and a half years, the lidars collected a wealth of data about the environment and average wind conditions at the proposed site, confirming that the project area experiences strong and consistent winds, and is a suitable location for generating electricity from the wind. Additionally, floating lidars have been deployed in conjunction with a recent wind energy project in France. Again, the location was too challenging for other WRA tools like met masts to be deployed effectively. Floating lidar closed the technological gap, ran without using vast amounts of energy, and provided reliable insights in a timely manner. These insights helped define the capacity of future wind farms in the area, and positioned France well in a competitive European wind energy market.

Because both the Australian and French governments were interested in increasing their wind power usage, these floating lidar-enabled WRAs were a crucial step in understanding the offshore wind resources, siting and operating the wind farms, and developing the infrastructure that will lead to a more sustainable future.

As governments and policymakers across the globe focus their attention on addressing the negative impacts of climate change, renewable energy sources like wind power will be increasingly imperative to power our planet for generations to come. Wind resources must be properly assessed to ensure reliable and efficient construction of wind energy infrastructure. Technological advancements have made this process faster, easier, and more cost-effective than ever. With vertical profiling, scanning, and floating lidar solutions, wind energy will no longer seem like a costly inconvenience but a promising endeavor for good.

Innovative wrench design

Wright offers the Wright Grip 2.0 wrench design that has more steel-to-fastener contact in high-stress areas to stiffen the jaws, increase tool strength, and reduce permanent jaw spread. The new design keeps the wrench from slipping to ensure the user’s safety. Wright Grip 2.0 provides more torque with less fastener damage, distributing stress evenly over a larger contact area and away from the fastener corners. The design incorporates a series of strategically placed teeth or grooves on the insides of the wrench’s two jaws. These teeth allow for a better seating of the wrench on a fastener. One fastener corner locks into the groove so the fastener won’t slip or twist out of the wrench under load. Wright Grip 2.0 is constructed with added premium Wright alloy steel for increased strength and precision broaching for consistent quality and tolerances. Precision-placed protrusions are custom engineered for each wrench size to keep it seated on the fastener, increase torque, and reduce slippage.

How V2G Reduces Emissions

V2G (vehicle-to-grid) technology is drawing a lot of attention in the electric vehicle (EV) charging world, but perhaps you are not exactly sure what it is and how it works. In simple terms, V2G is a bidirectional connection between an electric vehicle and the power grid that enables a two-way flow of power, to either charge the EV from the grid or discharge the vehicle, feeding power back into the grid.

Market signals from the grid are vital in deciding when to charge and when to put power back. During peak Time of Use (TOU) demand, the grid could draw from the stored energy in the EV battery to help meet demand, versus starting a peaker plant or other battery energy storage solution.

Strategically planning when to draw power from the grid will be crucial element for maximizing renewable sources and lowering emissions. Fleet vehicles are often uniquely suited to V2G applications due to their predictable usage patterns. Unused stored energy in their batteries can be utilized to either supply energy back to the grid during peak demand periods (an alternative to starting peaker plants), or during times when vehicles need a charge during a high TOU rate, while idle vehicles are available for energy transfer. This is the concept of peak shaving. Overnighting those vehicles that are off shift allows them to recharge when energy costs are at their lowest. Predictable charging patterns provide an ideal condition for V2G applications by using stored energy in batteries, while

planning enough time to charge vehicles again for the next day fully. School buses are a prime example of a fleet with predictable charging patterns, so this article will focus on the environmental impact of electrifying the nation’s yellow buses.

Lower Greenhouse Gas Emissions

With 480,000 buses carrying up to half of the nation’s children to school and back, school buses are the largest form of public transportation in the United States. Using V2G technology over the lifetime of a bus, fleet operators could eliminate an average of 1,000 metric tons of CO2-equivalent greenhouse gas per bus. This is the CO2 equivalent of taking 19 cars off the road (cars typically emit 4.6 metric tons of CO2 annually, for an average of 12 years).

One Bus Produces the Equivalent of 19 Passenger Cars Worth of CO2 Emissions, V2G can also eliminate air pollution from fossil fuel power plants working over capacity to accommodate high power demand fluctuations. Utilities rely on power from non-

renewable energy sources to meet demand during peak hours. Offsetting this power demand by using stored EV power can significantly reduce CO2 emissions.

In a Columbian University study titled “Vehicle-Grid Integration in California: A Cost-Benefit Comparison Study,” Francisco Galtieri concluded that electric buses using V2G could mitigate energy production from natural gas “peaking” power plants. Galtieri states that fleets providing power for peak shaving can potentially manage energy demand and eliminate short-term spikes. His model proposes that a fleet of 1,550 electric buses could reduce CO2 emissions by 5,500 tons over five years, significantly reducing local air pollution.

Maximize Renewable Energy

Using the stored power in EVs, school bus fleet operators can play a key role in largescale integration of renewable energy sources (such as solar and wind) into the power grid; V2G-capable commercial vehicles can absorb renewable energy when it’s available, and discharge it back into the grid when not accessible.

In 2018, the Environmental Research Letters published a study titled “The Neglected Social Dimensions to a Vehicle-to-Grid Transition: A Critical and Systematic Review.” The study analyzed the effect of V2G if applied to light-duty motor vehicles registered in the PJM Interconnection territory, the largest US power grid operator. The study concluded that “on a system operator scale, introducing V2G increases renewable energy development by 51 GW in the PJM Interconnection, an increase of nearly 30 percent compared to scenarios without V2G.”

V2G Infrastructure Considerations

Because V2G bi-directional charging is relatively new to the industry, commercial fleet operators must consider several factors when planning a charging infrastructure. Equipment is the first consideration. Fleets must be equipped with vehicles and Electric Vehicle Supply Equipment (EVSE) that can support bi-directional charging. Operators will need UL 1741-SA certified Level 3 DC fast chargers (DCFC) that run on 480 3-phase power.

Fleet operators should also reach out to a utility rep to establish an interconnect agreement that ensures they will buy power back. Utility reps will provide information about potential upgrades that may be required because of the new loads from EVSE, such as a new service line or an upgraded distribution transformer. Your local utility may also offer EVSE rebates to reduce the capital cost, so it’s recommended that you contact a rep early in the V2G infrastructure planning process. Other considerations include selecting a utility aggregator, determining site layout, future planning, and steps to mitigate installation costs. Once the system is in place, both fleet operators and their local grid will reap the long-term benefits afforded by this novel technology.

Growing the Lithium Industry in North America

There are 300 electric car manufacturers in China, according to the latest research from Xinhua. It dominates the global EV market, and, in turn, dominates all aspects of the lithium-ion battery supply chain. In fact, there’s so much lithium in China that government regulators have capped production, yet it continues to control and dominate the global lithium market.

China is 10 years ahead of the world in every respect. However, now that the transition to electric vehicles is in full swing across Western Europe and North America, the demand for lithium has increased, and will continue to do so.

The world does not lack in actual lithium; it lacks mineable lithium. It also lacks the processing facilities to convert 6 percent lithium spodumene into a usable raw material (hydroxide or carbonate) for the battery industry. In North America today, there isn’t an integrated lithium producer or significant lithium mining. There has been lots of movement to remedy this, but solutions are still years away, and many of them will die on the drawing board.

Whilst the US Geological Survey estimates China to be fourth in the world for lithium reserves (1.5m tons of lithium content), it has more than 70 percent of worldwide capacity for the supply of lithium-ion batteries. The United States is currently over-reliant on China for battery production, which is a risk on many levels.

Where does this leave North America, the birthplace of the massproduced car? Can it maintain its leading position over the course of the next decade and beyond?

In June 2021, The White House announced plans to secure an end-to-end domestic supply chain for advanced batteries. President Biden even said, “we need automakers and other companies to keep investing here in America, and not take the benefits of our public investments and expand electric vehicles and battery manufacturing abroad.”


US automakers are also recognizing the need to invest in North America battery and lithium firms. Only recently have we seen investments and subsequent announcements from household auto brands, promoting plans to build one of the world’s largest battery facilities in Ohio, and potentially building two more plants in the next four years. We have also seen plans from a big global tech conglomerate to boost production capacity of batteries for a well-known US automaker in Nevada, in an investment expected to exceed $100 million.

The issue automakers have in the United States is not just sourcing lithium, but also processing the raw materials.

Those who count on wind or solar power systems to run their businesses, homes − and lifestyles − turn to Crown for renewable power storage solutions.

mined, to the next level of the value chain. For this to work, a sustainable and fully integrated lithium hydroxide processing plant will need to be built in North America. This will allow tens of mining operations in Canada to actively pursue production of lithium for the North American auto industry.

Transitioning to Electric Equipment

With electric construction equipment now hitting the market, many people have questions. Which machines can be electric? Do electric machines have the same power as diesel? What kind of charging and runtime are we talking about here?

What machines can even be electric?

While some machines, like aerial lifts and forklifts, have been electrified for years, electric earthmoving equipment, like excavators and wheel loaders, are just now becoming commercially available. So far, they’re mostly compact models because of current battery capabilities.

As advances continue in research, development, and charging infrastructure, battery power and battery life will improve to allow for the electrification of bigger machines (such as excavators closer to the 20-ton range). Electrification is under the spotlight now, so we expect great advancements in the not-so-distant future.

What is required to charge an electric compact machine?

The more power you can put in, the faster it will charge — kind of like filling your car

As an example, an electric compact wheel loader charging on a 240-volt, Level 2, AC setup should be done in about six hours, empty to full. A common household outlet would do the job in 24 hours.

There are also options like off-board fast chargers and solar-powered chargers that will gain popularity in the coming years. What I would not suggest is charging with a gaspowered generator, because that defeats the main purpose of electric equipment: to be more environmentally friendly.

How long will it hold a charge? Will that affect my workday?

It depends. A compact wheel loader or excavator can be used in so many ways. Different applications can affect how long the batteries last. For most models out there today, you can expect four to six hours of actual work. It’s important to remember that, while a crew

The Story Begins with Energy Throughput

Energy Throughput gives the amortized energy in and out of a battery over its entire life cycle. Energy Density is important, but not as important as Energy Throughput.

What is Energy Throughput? Add up all the cycles a battery is capable of. For a back-of-the-envelope comparison, use 10,000 for LFP, and 2300 for NMC. Multiply this by the sum of energy for all those individual cycles. That is the more valuable metric for a battery instead of energy density. Energy Density and related metrics of rated capacity of batteries only apply - in general - to the battery at the Beginning of Life (BOL). At the End of Life for a battery (EOL), we generally calculate this as when the energy capacity falls below 80 percent of rated capacity. There are, of course variations in the calculations, but the 80 percent figure is a good rule of thumb, and works well for business calculations such as return on investment, and amortization over a certain period of time for long term investing.

For example, your phone battery will die in 2-3 years if it is NMC, yet it will last at least three times that with LFP. The only thing you notice is that each charge does not last as long, but the battery life is greatly extended past 2-3 years. The simplified graph shown gives an illustration of the phenomenon.

NMC at beginning of life looks better than LFP. However, NMC declines at a rapid rate, and LFP soon overtakes NMC in the long run.

EV manufacturers know that the LFP battery will last at least 3 times longer than the NMC. Thus, when pack replacement comes around, it will be further into the future than with the NMC. Thus, the amortized cost per kilowatt hour over the life of the pack is better with LFP, even though, at first glance, the energy density of the NMC beats LFP. Would you rather replace your EV battery after 10 years, or after 3 years? That is the offering with LFP.

It must be noted, however, that there are still applications for NMC. Specifically, in performance vehicles where the life of the battery is not expected to go beyond 2-3 years. There are “hot rods” or racing vehicles that fall into this category. Also, some luxury brands may not be as concerned with the short battery life of the NMC chemistry, when the owner can expect to upgrade more often to get the expected luxury performance of the vehicle.

John Goodenough, a researcher at the University of Texas, invented the LFP cell around 1996. Owners of the patents included A123, Hydro-Quebec, and the University of Texas. The main patents expired in 2017, according to the US Patent office.

At the time of the patent expiration, China activated dozens of gigafactories that produced LFP in unheard of quantities. This action by the Chinese factories made LFP affordable across the board internationally. We can now purchase consumer LFP batteries off Amazon thanks to these Chinese gigafactories. One factor that influenced this decision by the Chinese was that China decided to convert all their buses to electric around that time, and LFP was one way of making this happen on


the cell level. Also, for EVs in China, NMC was not allowed because of safety reasons, and so LFP was the obvious choice EV manufacturers began to integrate LFP into their EV architectures in 2020 and 2021. Before this point, the Energy Storage System (ESS) markets were the only big players purchasing the LFP cells. Large players in the EV market are converting their fleets to LFP.

The EV players chose to integrate LFP in their systems around 2020 and 2022, because the remainder of certain patents for the technology expired in Europe in 2020, and in North America in 2021. Thus, factories around the world began an enormous effort to make available the LFP cell for the EV market. Today, the EV manufacturers account for approximately 80 percent of the LFP demand. Within a two-year period, most of the major the EV

manufacturers switched from NMC to LFP.

How did this play out? This extreme change in the world market for cells completely disrupted the supply chains. The ESS market had integrated the LFP cells in various designs for over a decade. The above graph explained why. Amortization of assets over a long time period is extremely important in utility applications. Utilities make calculations in terms of decades, and, preferably, in terms of three decades (where possible) for expensive and large grid assets.

Furthermore, within a chemistry, there are different electrolyte recipes for a power dominant application versus an energy dominant application. For the ESS world, the focus is on energy dominant chemistries. For the EV world, the focus is on power dominant chemistries, since there are major current spikes in any EV drive cycle. ESS current draw curves tend to be more stable than the EV drive cycle models. Certain suppliers have dedicated production lines for ESS electrolyte recipes; long term partners can secure dedicated ESS LFP production lines for these special business relationships. However, since 2020, EV cells have been sneaking their way into the ESS supply chain, due to the enormous increase in demand.

Up until 2020 ESS manufacturers enjoyed a very stable cell market. The EV players came in and, within a two-year period, took up around 80 percent of the supply chain that was formerly the domain of ESS. This is a very big phenomenon. Today, ESS accounts for 13 percent of LFP demand. This is a major reorganization of the entire global supply chain for battery cells. IHS Market projects that, by 2025, EVs will have 90 percent of the LFP cell demand.

Projections of pricing predict that the price increases will not stabilize until 2024, when several LFP factories begin to come online and relieve the pressure of the supply chains due to the exponential increase in demand from the EV market.

At the moment, those in the ESS business without long term

supply agreements cannot find LFP cells. This means that hose just entering into the ESS market cannot source LFP cells. There are certain manufacturers that are focused on the ESS market for their production lines and supply chains. Those in the ESS business that have nurtured the relationships with their cell suppliers, who are dedicated with allocated production lines for ESS with the proper LFP electrolyte recipes, are in a better position to continue supplying their customers.

Those who have developed these close, and established relationships with top tier global suppliers have lead times of a couple of months. Those without these close relationships have lead times out 12-13 months. Those using LFP with dedicated ESS suppliers, combined with proprietary software management tools, are in a good position to avoid disruption in their supply chains with LFP cells.

The energy storage world has been revolutionized within the last 5-10 years. The electric vehicle world has also been revolutionized. Now, as opposed to 5-10 years ago, we are at the stage where such industries are profitable. For those of us who have participated in these industries over the past 20 years, it has been a long time coming. All of our efforts over the years have now paid off. It is indeed chaotic at this moment, but things will settle down in about 2 years or so. By then, our industry will have been established as something total new and profitable, and also a major player on the world economic stage.

Power Outages, Resilience & Energy Storage

Safety & transparency in battery energy storage systems (BESS): UL 9540A & 9540

The Department of Energy estimates that centralized, top-down utility power outages cost U.S. businesses approximately $150 billion in direct losses annually. Indirect losses make the cost much higher. As a Berkeley Lab study highlighted across 6 states, state officials and utility executives characteristically neglect to calculate the social and economic costs of longer and more frequent power outages arising from indirect impacts, such as school closings, food spoilage, supply chain disruptions, and deleterious health outcomes. The U.S. now has more power outages than any other industrialized nation, with the number of annual outages doubling from 50 to more than 100 over the past 5 years. Significantly, both the frequency and duration of grid failures is at the highest level since 2013, as extreme weather events ravage antiquated and ill-maintained utility infrastructure. While 40 states are currently experiencing longer grid outages, California, Louisiana, and Maine are at the forefront, with a greater than 50 percent increase in power outage duration.

Centralized power outages are, in large part, being driven by severe weather and climate disasters. NOAA reports that during 2021, there were 20 different billion-dollar weather and climate disasters in the U.S., costing a total of $152.6 billion in damages. In December, NOAA noted that the temperature of the contiguous 48 states was the warmest on record, measuring 6.7 degrees Fahrenheit above average. As of June 2022, there have already been 9 separate billion-dollar weather and climate disasters in the U.S. Back in April, the White House announced that extreme climate-driven floods, drought, heat waves, wildfires and hurricanes could cost the U.S. federal budget approximately $2 trillion per year by the end of the century. The Office of Management and Budget also projected that the U.S. government could spend an additional $25 billion to $128 billion per year in “areas such as coastal disaster relief, flood insurance, crop insurance, health-care insurance, wildland fire suppression and flooding at federal facilities”.

These mounting numbers are almost too large to comprehend, but clearly suggest that climate driven disasters are increasing in number and severity, eroding our economic wellbeing, destroying property, causing deaths, and undermining our ability to access reliable and safe power 24/7. If utilities and power companies are to make the necessary investments to reduce CO2 and GHG emissions driving climate-driven disasters, increase their portfolio of renewable generation, and ‘harden’ the centralized power grid to withstand mounting hurricanes, heat waves, severe winds, and flooding, they will have to spend trillions of dollars.

A more efficient, timely, and costeffective solution

Distributed customer-sited, behind the meter battery energy storage systems (BESS) + solar can help solve these issues. All over the U.S., utility customers are choosing to install batteries as back-up, as well as to discharge daily during utility-based high-rate periods, such as Time-Of-Use (TOU), or to participate in demand charge management programs – all of which serve to lower utility bills, prevent losses from power outages and, in aggregate, decrease overall electrical loads on the grid. Without distributed energy storage, renewable sources of energy are intermittent and unreliable. So, too, is the centralized grid in emergency and extreme weather events during which the centralized delivery of power fails. Distributed and customer-sited energy storage eliminates that intermittency, providing stored power when people need it, long after the sun has set, the wind has stopped blowing, or the grid has failed (or been willfully shut off by the utility during PSPS events). Distributed energy storage is critical to creating energy security and resilience in homes, businesses, hospitals, schools, and communities. Energy storage plays a vital role in the transition to a higher percentage of renewables in our energy portfolio, and provides reserves through the worst climatic conditions and weather events.

The 2020s were predicted to be “the energy storage decade”, with the world exceeding a terawatt-hour of installations. While multiple lithium-ion chemistries are being developed and deployed across the energy storage industry, experts are bullish on lithium ferro phosphate (LFP) surpassing cobalt-based lithium-


ion alternatives, such as manganese cobalt (NMC). Given the sheer number of significant battery recalls over the past several years due to “thermal events” (in which cobalt-based lithium-ion batteries (NMC & NCA) overheat, catch fire, and even explode) it is no surprise that the non-cobalt based LFP chemistry is being adopted by manufacturers and customers alike. If consumers, Fire Marshals and

What is the UL 9540A FireSafety Test Method?

UL 9540A is a series of progressive tests in which the cell, battery module, and larger unit or full installation level components are forced into a state of thermal runaway, using heaters with thermal and gas analysis, to document and characterize the performance profile across different lithium-ion chemistries (LCO, NMC, NCA, LFP) and form factors (pouch, prismatic, cylindrical) used by battery manufacturers. During a test, the equipment being tested is put into safe, controlled environments, where there are “witness boards” that collect shrapnel and other materials if smoke, fire, and/or explosions occur. Test results demonstrate that not all chemistries, form factors, and manufacturing processes provide the same results with an equal level of risk, hazard, and safety.

Why is transparency with UL 9540A test results so important?

Transparency is crucial so customers can make informed decisions about the BESS they are purchasing, and the risk profile that comes along with it. Many manufacturers are choosing the least costly

option to develop their technologies and gain market share, which can pose a higher risk profile and price for customers on the back end when a BESS fails.

Not all “lithium-ion” batteries carry the same hazard and risk profile. With more transparency on behalf of manufacturers – identifying publicly the chemistry, form factor, and manufacturing processes behind the energy storage solutions they

produce - all stakeholders in the energy storage industry can begin to understand the different risk profiles available across the range of “lithium-ion” chemistries in the market. This type of disclosure will serve to drive innovation and propel the entire energy storage industry forward, which is so critical in the face of mounting climate change, severe weather events, and centralized utility power outages.

X-BATT has combined coal with its low-cost, resin-based technology to create full-cell batteries. Early tests in full coin cells show that the company’s batteries, utilizing this coal composite anode material, have reached over 400 cycles. X-BATT has also scaled-up this technology, with the help of the Battery Innovation Center, into single layer pouch cells that have surpassed 100 cycles and are continuing to perform well. The benefits of this new material don’t stop at its increased performance, this technology could also lead to a domestic source for anode material, helping the United States reduce reliance on foreign countries for the critical materials necessary to support the increased demand for electrification.

To help further its research, the Department of Energy’s National Energy Technology Laboratory (NETL) awarded Semplastics, X-BATT’s parent company a $1 million contract to produce polymer derived ceramic composite anodes using coal as a carbon source for lithium-ion batteries. The company has discovered that adding a carbon source, such as coal, to the PDC material offers stability and normalizes charge / discharge behavior, improving cycling life and decreasing nominal voltage.

One constant of the climate crisis has been that every year, extreme weather events show the threat that rising temperatures pose to people across the world, as well as to the electrical grids we rely on to power our societies. Even with several months left in 2022, this year has proven to be particularly brutal. Challenges that have persisted for years have continued with no end in sight, such as the drought in the American West draining hydropower capacity, and demand outstripping supply on Texas’ beleaguered grid.

Perhaps the most headline-grabbing climate event of the year, though, was the crippling heatwave that struck Europe over the summer. Even in southern European countries used to fairly hot summers, temperatures soared past 40°C (104°F) and even approached 50°C (122°F) in some places. Meanwhile, typically mild northern European countries like the United Kingdom saw their infrastructure buckling as they experienced the hottest days ever recorded. When the worst of the heat had subsided by August, thousands of tragic deaths could be attributed to the heat.

Here in Canada, we’ve had a relatively mild summer, but we experienced our own recordbreaking heat in the summer of 2021, when our Western provinces grappled with the “heat dome” that hovered over Western North America. Lytton, British Columbia recorded Canada’s highest ever temperature (49.6°C/121.3°F) shortly before a wildfire destroyed the town; across the West, over 800 deaths could be attributed to the heat.

Grid Operators Prepare for the New Normal

Both this year’s European heat wave and last year’s in Canada struck parts of the world not normally accustomed to sweltering summers. This is especially true at home. In most of Europe, air conditioning is exceedingly rare, with less than 5 percent of homes in Germany, France, and the UK having it. A/C is more common in Canada, installed in over 60 percent of homes, though this has traditionally been much lower in provinces with mild summers. This compares to nearly 90 percent of homes in the United States.

The lower usage of A/C speaks to how both of these regions have reasonably been more concerned with keeping warm in the winter. Many homes are illequipped to deal with scorching heat. This will have to change soon as the cold countries in the northern hemisphere seek to head off deaths related to heat waves, and avoid the crippling heat that can bring these societies to a halt. While global A/C usage is expected to surge in the coming decades as families in emerging economies gain the means to install units, cold countries in the global north also need to prepare for the grid consequences of higher A/C usage, and generally higher summer demand. Some countries are already confronting this; in July, in a bid to conserve electricity, Spain announced that public buildings could not set their A/C below 27°C/80.6°F.

Grid operators in Canada and Europe should take these heatwaves as a warning of things to come. As summer heatwaves grow in intensity and duration, and temperatures in general rise, more families will turn to A/C to cope. With HVAC systems being the

biggest energy consumers of homes, this will lead to greatly increased electricity demand. This will naturally result in the need for more supply, but increasing summer demand isn’t the only way operators will need to change how they run grids. Many utilities in Canada and Europe plan for scheduled maintenance in the summer, while the greater stress on the grid is bringing aging infrastructure to its breaking point sooner than expected. In a vicious cycle, higher summer demand will also come as drought ripples through many regions of Canada and Europe, reducing the capacity for hydropower as rivers and reservoirs dry up. This is an especially acute concern in Canada, where hydro makes up the largest proportion of electricity generation.

How are grid operators to prepare for the higher summer demand in years ahead in countries where demand typically peaks in the winter? While higher generation will be necessary, greatly expanding power supply requires massive infrastructure investments. These projects can take years, if not decades, to come to full fruition. There is also the matter of the grid’s capacity; transmission and distribution networks can only carry so much electricity before operators must curtail generation. This is a particular concern for intermittent sources like solar and wind, which must make up the bulk of new generation facilities to meet clean energy goals. Grid capacity will especially need to increase in Europe, which hosts both aggressive renewable initiatives and grid infrastructure that’s decades old.

The good news, for both grid operators and their customers, is that there are immediate ways to improve grid capacity. Operators in Canada and Europe can turn to software-based solutions to maximize their existing assets while they plan for long-term upgrades to the grid. Energy management software can optimize energy use when demand is highest, and pairs particularly well with energy storage, sending intermittent solar and wind to storage when demand is low or the grid is nearing capacity. Cleantech software can also give operators and developers the means to aggregate distributed assets while they wait for utility-scale

generation facilities to come online, helping communities increase capacity while meeting their clean energy goals.

The surge in A/C across the globe is one of many impacts of the warming climate; homes will inevitably increase their energy usage so residents can survive the summer. Utilities and grid operators can do their part to ensure this demand is met from clean sources. However, that will require expanding the capacity of the grid, especially in the global north where millions of homes have the means to immediately install an A/C but have avoided it up to now. Cleantech software is the key to bridging the gap to increased utility-scale clean power generation, and can even make small, distributed assets meet a community’s energy needsincluding those home A/C units.
