he Good Old Days don’t seem to be as long ago as they used to. My first instinct is to place the blame on getting older, and the phenomenon of time flying by ever faster with each passing year. Looking back, I’ve always been able to reconcile that interpretation with the reality that the pace of life itself hasn’t changed – I’m the one that’s changed. For sure, technology keeps advancing at mind-blowing speed. Yet, even that aspect of our daily lives has followed a logical timeline, dictated not so much by technology itself as our capacity to absorb those advances in a way that makes sense to us. Technology is useless without a willing user. I’m not talking about the luddites, or those of us who tend to be slower to adapt to the latest version, but how society follows a natural progression of being shocked and awed, then curious, and finally, accepting the “new” and making it the “norm”. Nothing dates a film quite like watching the main character confidently start filming something with their video camera instead of a phone. Phones are second nature. Does anyone really even refer to them as “cell phones” anymore? (Other than on the never-ending paperwork required to check in at the doctor. And why are we still using reams of paper?!) Few people under the age of 70 wish to be caught without their phones. The early ancestors of the modern cell phone were bulky, ugly as sin, and cost a small fortune. If you could handle the monstrous price and were willing to tote a bag big enough to fit all the extra paraphernalia, you were rocking a major status symbol. Nowadays, if they own little else, the poorest among us are able to afford a cell phone. I read something rather profound the other day. It referred to a single day in my childhood, when I went outside to play with all of my friends, never realizing that it would be the last time that would ever happen. That hit home. It also made me think about some of the games I used to play. I was kind of an idiot as a kid. One game that beautifully illustrates my naiveté happened to be a favorite of mine: Mother May I. The object of this game is to be the first to make it over the finish line. All players start in the same place, on the starting line. One player is nominated – or, depending on the dynamic of your friend group, appoints themselves – as the “Mother”. In the guise of impartiality, the Mother faces away from all of the players. Each player takes turns asking the Mother if they can move forward. Anything from, “Mother may I take one umbrella step forward?”, to “Mother may I take two baby steps?”. The Mother either says that you can, or she rejects your request, or she gives you an alternative. The person who crosses the finish line first, wins. Yay! Only decades later did it occur to me what a hollow victory that really was. As if, by having the Mother face away from the players, all her other senses stopped working. Did I think Mother couldn’t recognize our voices? Or maybe I believed that Mother gave everyone an equal chance to win? Nope. Mother chose the winner every time. Years of hard work, rejection, wildly varying compensation, and learning to weigh opportunities, has taught me the value of competition. Building a product people want more than they want to hold onto their money equals success. Forcing people to pay for something they don’t want? Depending on your point of view, that could be anything from theft to the price of creating a better world. At a minimum, it may be seen as severe economic regimentation. Do what Mother says or be left behind. I would love to drive an electric car that improves the quality of my life. At the very least, one that is able to match the performance of my gas-powered vehicle, recharge in the same amount of time it takes to fill my tank, and still be ready to go the distance after sitting idle for a few weeks. I would love to heat and cool my home with solar panels as reliably as I can with natural gas. I would love for wind turbines to cause zero harm to wildlife, and be able to generate as much electricity as coal and oil. All without forcing me to live beyond my means. While the government may be expert at spending my money on things I don’t really want (at least not yet), I still cling, ever optimistically, to the idea of the free market. I believe that, just as we have with smart phones, society will evolve. We’ll get there. My hope is that we let these changes happen organically, at a pace more in tune with the natural passing of time.

Robotic fish designed to enable efficient offshore inspections

Verlume has joined with consortium partners to progress the development of an autonomous underwater robot that moves like a fish to enable efficient offshore inspection regimes in harsh and hard-to-reach environments. The agile biomimetic autonomous underwater vehicle (AUV), named RoboFish, is made up of several self-contained modules with self-managed battery and actuator control for full-body, autonomous movement around underwater structures. RoboFish was initially devised by researchers at the University of York, Department of Electrical Engineering and the University of Strathclyde, Department of Naval Architecture, Ocean & Marine Engineering with grant support from the EPSRC Supergen Offshore Renewable Energy Hub. The first RoboFish prototype was completed in summer 2020 and research to improve it and apply it to new applications is ongoing. Two conference papers and a journal paper have been published on the RoboFish prototype, with another journal paper due to be published this year on control of the swimming gait with machine learning.

Solar beehive protects bees

Hanwha Group has introduced the Solar Beehive, a photovoltaic low-carbon solar beehive that uses electricity generated from solar energy. Through this project, Hanwha aims to increase bee populations by maintaining a stable environment for growth while promoting the importance of preserving biodiversity. About 40,000 bees that live in the Solar Beehive will help pollinate fruit trees and vegetation in nearby wooded areas. The program will also collect data on bee population growth and activities. The Hanwha Solar Beehive consists of two parts: a smart internal beehive that controls a growing environment for bees and an external structure that provides electricity to the beehive. The solar panels installed on top of the Solar Beehive generate electricity used to automatically monitor and control the temperature, humidity, water, and food inside the structure. The beehive also contains a smart system that monitors and controls this data through an app in real time. Prioritizing both the health and safety of the insects housed inside, the Solar Beehive can also detect the presence of hornets, the natural enemy of honey bees, by measuring and analyzing ambient sound. When hornets approach the beehive, the entrance will narrow into a passage small enough that only bees can pass through.

Long-range solar car-sharing

Lightyear is partnering with The Sharing Group to supply 5000 Lightyear Two vehicles to its car-sharing platform MyWheels. This high volume series will be available to the MyWheels fleet as of 2025. In addition, in 2023, the Lightyear One will also be added to the MyWheels platform. With this partnership, Lightyear and The Sharing Group enable Lightyear’s mission to bring clean mobility to everyone, everywhere and offer grid-independency to users of MyWheels. Lightyear One is Lightyear's first model that will only be produced in a limited quantity. The Lightyear One will go into production in late summer 2022, and first customer deliveries will begin by the end of the year. MyWheels is establishing a sharing campaign for loyal members to be able to drive a Lightyear One as early as 2023. Lightyear Two will be the mass-market model of the technology manufacturer and will go to market in 2024/2025 with a starting price of 30,000 euros. Next to the environmental benefits of solar electric vehicles, the long-term economics are advantageous as well. Vehicles like the Lightyear One and Two generate power themselves and have less moving parts than other cars so their maintenance and operation costs will be comparatively low.

US renewable energy demands unprecedented cross-sector integration by Brad Barth


resident Biden’s pledge to install offshore wind1 across almost the entire US coastline, in the next eight years, will require unprecedented cross-sector integration. Rapidly scaling this renewable energy source entails the interlinking of previously separate parts, processes, skills, and project partners – from sectors as diverse as oil and gas, hydrogen, and batteries. This is a particularly significant challenge, as the US domestic offshore supply chain is not currently equipped with the necessary manufacturing, materials, transportation, and installation infrastructure. Integration and knowledge sharing with more mature regions such as Europe is to be expected. In a similar vein, we also must keep in view the effect of volatile markets that surround the wind industry. Material shortages, supply chain crunches, and surging energy costs are already harming profitability, forcing some wind manufacturers to retreat from markets, raise prices, and reduce products. With no commercialscale offshore wind projects operational in the US today, scaling up capacity within the proposed timeline will require the country overcoming multiple barriers, to achieve in eight years what others achieved over decades. Reaching this scale and speed of development will require new project management models that facilitate the aforementioned integration across companies, components, and build stages, to fuel high-speed, agile, and iterative construction. Organizations will have to transfer institutional memory from previous projects that could aid construction of novel new concepts, such as floating wind. And, crucially, delivery models and contracts that split risks among all participants will need project management systems capable of synchronizing, standardizing, and monitoring project progress across many diverse components and stakeholders.

The integration challenge

Integrating resources across previously separate sectors is no easy task. It’s not just resources; we will also see a blend of assets and components adapted from other industries, be it oil rig infrastructure, metallic alloys adapted from aerospace applications, or cable protection systems adapted from subsea oil and gas pipelines2. Offshore wind platforms will also need to intersect with existing infrastructure from other energy sectors like gas pipelines and electricity grids. While this integration will allow rapid climbing of the offshore wind maturity curve, there remains a steep task ahead, with an urgent need to connect data. Doing so will provide visibility across a diverse array of suppliers, partners, components, and build phases. It’s important to note that, in addition to acting as a desirable success accelerant, data sharing is non-negotiable to offshore wind’s success. Wide access to data is not only essential to novel wind concepts, but cumbersome approvals processes will require rapid and iterative development, where construction is continually refined by connecting data across each build phase. Similarly, progressive delivery and design-build projects (where construction

and design happen continuously across distinct scopes of work, and integrated risks are shared among participants) will need real-time data transparency among all project partners. A post-pandemic supply chain squeeze, exacerbated by massive additional demand for materials catalyzed by the US Infrastructure Investment and Jobs Act (IIJA, has created a new imperative for predictive planning, procurement, and logistics across all components; this will aid in anticipating and averting shortages.

and trust among diverse project teams. To help overcome the supply chain challenges at play, barcode, RFID, and GPS sensors enable real-time identification3 and tracking of all components, equipment, and tools, to help predict and prevent material shortages and logistics issues. Also, predictive pricing and scheduling can model the impact of different scenarios, from inflation to supply chain crunches, on everything from cash flow to delivery dates at concept stage.

Collaborative project management methods

Navigating the challenge

It’s clear to see, given the complex ecosystem of expertise, components, partners, and build phases ever expanding to support the rapid scalability of offshore wind, that new project controls systems capable of advanced information sharing are a necessity. Project partners will need real-time visibility of construction site activity, people, equipment, and materials to predict and prevent delays caused by lack of resource availability. Crucially, they will need live oversight of project progress against both cost and time constraints to avoid schedule or budget overruns. Encouragingly, the expansion of Construction 4.0 technologies – from data analytics, to artificial intelligence (AI) and the Internet of Things (IoT) – is enabling organizations to create a digital feedback loop by sharing insights and information across end-to-end build phases. This will drive dynamic, data-driven construction processes that are collaboratively and continually refined across project lifecycles. Integrated project management platforms allow insights to be captured and crossfertilized from one project to another, creating a virtuous circle of data where each new project grows progressively “smarter” than the last. Advanced project controls systems can also ensure consistent tracking of progress on each task against predefined milestones or rules of credit, creating a predictable project-wide picture of progress. And digital twin technology can connect operational data from different project participants, enabling cross-departmental decision-making that creates closer alignment between diverse project partners. New technologies bring program and project data together to offer holistic real-time visibility across end-to-end lifecycles, helping foster transparency

The offshore wind industry in the US has an incredibly exciting future. Billed as one of the vital renewable technologies to support the country’s drive to net zero, we are quite literally in the midst of making history. And, because of how quickly offshore wind needs to grow – especially with the weight of combatting climate change resting on its shoulders – it is imperative that we address any barriers in the way of success. Integration is one such barrier; it’s also the best opportunity to unlock the vast insights and asset sharing capabilities available in the energy, construction, and engineering industries. The Construction 4.0 revolution holds the key to helping the US offshore wind industry deliver new capital projects more efficiently, and traverse the challenges of a sector where demand for new projects is far outpacing the construction industry’s capacity to keep up.

Solving Solar Challenges Through GIS Technology by Christopher Nichols


he decade of solar development continues. With a growing focus on climate change, the federal government1 has increasingly pushed for the expansion of alternative energy resources, such as solar farms. In response, in 2021, the American solar industry deployed2 a record 23.6 gigawatts of energy generating capacity. As a number of states, like New York, are aiming to install even more gigawatts by 2030 to meet national sustainability goals3, solar teams need greater flexibility, collaboration, and innovation in project plans. Geographic information systems (GIS)4 are important for project planning; they provide the flexibility needed to save time and team resources. Instead of what used to be a drawn-out process of conducting land research from several disparate sources, GIS gives solar teams up-to-date and useful information, right at their fingertips. Using data-rich mapping through the project planning phase, solar teams can be timely and effective in today’s competitive market. GIS can even help solar developers confidently overcome some of the industry’s biggest challenges.

GIS makes it easier for solar teams to save time searching for and identifying the right property, by providing all the necessary data in just minutes.

Challenge 1: Checking the Boxes – Land That Meets Project Criteria

After developers have successfully identified a property that meets criteria and specifications for their next project, the next step is to gain investor buy in. To do so, they have to prove the land’s value to potential investors, who may not be as familiar with the project details as the developer. Therefore, solar project leads need to clearly communicate the benefits of a land parcel, and outline key project points, to prove that it is a return-worthy investment. A solar developer has land data at their fingertips with GIS, as well as the capability to visualize it through custom graphs, interactive presentations, and plans. These visual resources are more likely to lead into investor buy in, as 40 percent of people5 are more inclined to respond positively to visual information.

First and foremost, the success of any new project depends on solar developers finding property in close proximity to the grid. From there, developers need to consider certain criteria (i.e., whether a land parcel is even buildable, if the area is prone to flooding, etc.) to truly be effective. Searching for land that meets that criteria is often no easy task. For instance, developers can spend countless days sifting through county records, aerial photography, and other available information to locate the data to identify proper distribution lines, transmission lines, and substations.

Challenge 2: Identifying Risks Before Experiencing Development Pitfalls

Due to the scarcity of available land near the grid, development professionals may find themselves quickly jumping to secure land parcels, just to beat out competition. Later, they uncover hidden risks not initially visible (such as when a developer invests in a “suitable property”, only to discover that the land is located in a flood zone). Armed with GIS technology, solar land developers have a greater probability of identifying risks before investing in a property – avoiding unidentified pitfalls such as topography challenges, wetlands, and land buildability.

Challenge 3: Meeting Financial and Investor Needs to Gain Project Buy-In

Challenge 4: Combatting the Labor Shortage & Remaining Organized

With the continued focus on achieving sustainability goals, the solar industry is in a high demand for top talent across the nation. In fact, the rate of solar jobs in the U.S. has increased 167 percent over the past decade6 – 5 times faster than growth rates of other industries. Despite demand for workers, however, the U.S. is currently experiencing a labor shortage that may cause staffing issues across solar teams.


2022 JULY• AUGUST ///

When solar land developers are ready to begin executing on their land plan (after receiving investor buy-in), they need to ensure their teams are well equipped to succeed. It’s key to have a clear vision, and a strong, collaborative team. Whether labor shortages affect staffing, teams are stretched thin, or developers are struggling to manage large teams, projects can sometimes be overwhelming and disorganized.

With GIS, solar land developers are equipped to better manage teams of all sizes. It provides easier collaboration from top to bottom - and across state lines - by creating one, centralized data source for all team members to collaborate, track progress, share project details, and more. Before venturing into your next solar project, ensure you’re armed with the right tools and technology to succeed at every step of the way.

Asymmetric Net Metering

Problems and solutions by Alex Bazhinov

The California Public Utility Commission’s (CPUC) latest proposal for net energy metering, (NEM) 3.0, has raised many questions and eyebrows within the residential solar and energy storage world. While California’s stance to diminish the potential return on investment (ROI) for residential solar has been temporarily paused, it brought up the imminent question: how can people protect themselves from potential rate increases? As residential solar continues to grow, initiatives like this threaten the industry’s momentum. They also pose potential risks that net metering creates. As the industry looks for answers, existing technology utilizes mitigation strategies to bring a solar return on investment in line with net metering.

Net metering and its problems

To understand this situation, people need to know what NEM is and where it stands today: with net metering, utilities only charge users for their net electricity purchases. If people generate excess solar, their electricity meter “runs backward,” reducing, or completely negating their bill. Opponents of net metering argue that residential solar owners are not paying their fair share for grid infrastructure usage, resulting in rate hikes that impact lower-income groups more than higher-income groups. Net metering’s opponents do not all agree on the residential rate structure that should prevail, but all solutions fall under the umbrella term: asymmetric net metering.

Asymmetric net metering

With asymmetric net metering, electricity purchases and sales are not equal. This structure has many different forms, with the most common being flat fees and net billing. Flat fees allow utility providers to determine a user’s monthly energy bill by net electricity imports. Still, there is an additional fixed monthly “grid access charge” for customers who want to sell their excess generation back to the grid. With net billing, the utility company compensates users at a lower rate for electricity sales back to the grid than they charge for electricity purchases. The current proposal from the CPUC levies both these forms of asymmetric net metering; this will result in a drastic extension in the payback period for an average home solar installation in California, and a likely backsliding of rooftop solar adoption. If passed, the CPUC proposal will be a big blow to the residential solar industry, given that California is the nationwide leader in residential solar deployment. Many fear this is a bellwether for future policy changes in other states across the nation.

Although the proposal includes both a “storage evolution fund” and an “equity fund” to rollout solar installations for lower-income and polluted communities, solar homeowners will still be disadvantaged; the proposal interrupts the dropping capital costs and improved financing structures that currently make solar extremely affordable for lower-income Californians. The takeaway from this push for asymmetric net metering is that generating excess solar energy during parts of the day, then selling it back to the grid, is likely not a sustainable long-term solution for homeowners with residential solar. However, there are several solutions available, even if asymmetric net metering takes hold across the country.

Undersize solar

Since a switch to asymmetric net metering will not impact the value of any energy that you self-consume, the most obvious (but least impactful) solution is to undersize a solar array so that it never generates excess electricity. The current NEM framework in California pays homeowners the “retail rate” – around 20 to 30 cents per kilowatt-hour (kWh) – for excess electricity sent back to the grid. This rate is also the same amount they originally pay to receive electricity from the grid. The new framework proposes to decrease this payment to around 5 cents per kWh, referred to as an “avoided cost” rate. To steer clear of this new “avoided cost” rate, and facilitate lower system costs, homeowners need to be more vigilant in monitoring their solar production. A home with limited energy production will be powered mostly by fossil fuel generation from the grid. System management and optimization will be critical factors in successfully adjusting to this new rate change for solar customers. New solar customers may not use all available rooftop space for a new solar array. If they are limited to building an overall smaller array, they will have to optimize their arrays to produce the maximum solar power to support their needs. On the other hand, existing solar customers may not quickly redesign their existing solar arrays. Still, they can easily

adjust to these new rate changes with energy management tools. Features such as monitoring, management, and even optimization can help homeowners curtail excess energy production. While this is a solution to help homeowners in the short term, this option is not the best solution for the industry; it slows down decarbonization, and our fight to reduce climate change impacts.

home energy assets to match solar generation profiles such as EV charge time, controlling HVAC, water heater timing, and pool pump operations. As it stands today, asymmetric net metering could be very detrimental to the solar industry. However, with a wellimplemented smart energy management system, a homeowner can maximize self-consumption of solar generation, minimize excess solar sales to the grid, and maximize the return on investment for residential solar systems by treating their home as an actively and intelligently-managed microgrid.

He had the idea for Lumin while tending to his first start up, DreamPower, which he founded at the University of Virginia’s iLab while earning his graduate degree at UVA’s Darden School of Business. Alex hails from Moscow, Russia, where he held senior finance positions in global firms, spending six years at Norilsk Nickel, the world’s largest nickel and palladium producer, and as CFO at the global manufacturing conglomerate, Sandvik.

Install batteries

Another option is to install a big enough battery to consume all your excess solar generation during the day to discharge at night. Initial costs of adding an energy storage system can be high, due to product pricing and installation fees. Still, homeowners will significantly benefit in the long run when pairing solar and storage together. A homeowner with an energy storage system can schedule many, or all, of a home’s loads during demand peaks, the specific times of day, or the season when power is highly required and used. Doing so avoids peak time-of-use energy charges from the utility, and lessens the home’s reliance on the grid when fossil fuel usage is at its highest. Besides providing power during demand peaks, energy storage systems maintain a steady energy flow during suboptimal weather conditions and grid outages. The latter may come with the additional benefit for California, which has had a number of large power outages due to grid instability over the past several years. The new proposal outlines a “storage evolution fund” that offers existing solar customers without energy storage systems (both residential and commercial) rebates of $200 per kWh for installing a battery system – under the condition of switching to NEM 3.0 within the next four years. The rebate decreases the longer a customer waits to change. Energy storage systems help all homeowners build their power grids, use sustainable electrical power, and greatly reduce dependence on the local grid.

Use a smart energy system

One of the best strategies for a homeowner is to maximize the use of solar power generated onsite. This would, in turn, minimize the use of energy imported from the grid at a higher price. The most efficient solution to achieve this goal is installing a smart energy management system that will intelligently control circuits, to ensure that homeowners are self-consuming as much of their solar as possible, whether or not the system has a paired battery. These solutions work with appliances, electric vehicle (EV) charging hardware, and solar and storage systems, to help homeowners address energy consumption, and load more precisely. This technology can also schedule various

Global solar PV installations are projected to see over 20 percent growth in 2022, surpassing the 200 GWdc barrier for the first time. This is necessitating an exponential increase in manufacturing capacities for everything from panels and modules, to inverters and trackers. But supply chain challenges continue to bubble up and threaten the future of the industry. Solar suppliers, manufacturers, developers, and utilities alike face great uncertainty surrounding the immediate future of the market, as the landscape continues to be riddled with volatility stemming from various factors. These include The Antidumping and Countervailing Duties (AD/CVD) Anti-Circumvention Petition, Section 201 Tariffs, the Department of Commerce Tariffs, ongoing supply chain issues stemming from COVID-19, and the Uyghur Forced Labor Prevention Act. The crux here is that supply chain disruptions stemming from these factors are increasing shipping and equipment costs for solar components, driving a spike in pricing, which causes project delays and further constrains the market. Until recently, declining PV system costs—which fell by more than 50 percent, on global average, from 2013 to 2020—have been a core reason for the explosive growth of the industry. In 2021, however, PV systems costs increased by 4 percent yearon-year due to shortages of components, raw materials, and labor, as well as rising shipping costs. Despite these new impediments, strong demand persists, resulting in installations in key markets and driving expansion. But, will this trajectory last?


Strategies and policies for supply chain resilience

A massive scale up is anticipated as demand for solar energy proliferates. The IEA predicts that almost two-thirds of electricity generation needs to be renewable by 2030, in order to set the world up to achieve the 2050 Paris Agreement target. There is a vast gap between what we have now, and what we need for the future. As it stands, the supply chain is not equipped to deliver to meet these goals. Meeting the goals would require adding 12 percent more renewable generating capacity each year, over the next eight years – double the current rate. This will require much faster deployment of renewable technologies to achieve the Net Zero Emissions by 2050 Scenario. New business players and regions (including leaders from the Oil & Gas segment) must join the transitioning efforts in the march toward renewables. Eventually, we will need to see whole new supply chains - without previous track records in renewables – emerging to deliver the immense scale up required to achieve net-zero. Making this work in terms of quality, safety, and competitiveness will be the key challenge in this transition. Additionally, government policies that are currently lagging will need to become more proactive and supportive to harness new investment and expand capacity. Many solar players expressed concern regarding the recent Department of Commerce investigation, announced in March of this year. Tariffs in the solar industry are not new (they have been around since 2012), but what was concerning to the industry was the level of uncertainty now facing developers and the deregulated market. The recent decision by the Administration, which pauses tariffs on South East Asian panel imports for two years, was very welcome. It does two things. First, it creates a sense of regulatory certainty for the investor community, which will spur development and The equation for sustainable growth construction activities. Solar project cost escalations create significant delays, as they In 2021, the US installed more wind, solar, and battery not only impact the CAPEX spend for developers, but also create issues with previously storage than any year in history.

action to protect your business. Using field data collected from independent on-site verification of critical suppliers and partners can help to customize risk assessment of your supply chain. These risks include business continuity, HSE vulnerability, logistics and inventory, security, technical capability, as well as governance and social engagement. On top of this, ESG has become a major focus for supply chain management; business ethics, responsible sourcing, and climate change are top priorities for the industry. The solar supply chain is very complex. Smart businesses must assess risks by supplier, project, geography, product category, and tier. This helps minimize shocks to demand, pricing, and logistics. It also drives supply chain value through a focus on risk management and process control. Ultimately, companies are able to build better supplier ecosystems that are based on transparency and trust. These capabilities are critical – not only to manage the volatilities stemming from today’s crises, but also to prepare for a sustainable future. Mere band-aid solutions are no longer enough to navigate the landscapes. Leading companies that emerge from crisis environments will be those with advanced supply chain management practices in place, both to mitigate a wide range of risks, and to perform under various market conditions. A saturated industry is a less resilient industry. Global supply chain diversification can reduce disruptions to ensure that a company is not fully reliant on potentially undependable sources, enabling them to pivot to alternatives as needed. For long-term sustainability of the solar industry, policymakers need to prioritize removing forced labor out of supply chains by increasing visibility, diversifying sourcing, incentivizing projects, and supporting research and development of innovative technologies.

As it continues to grow, the industry will to improve resilience throughout the entire solar supply chain, building more efficient business models that are better for companies, consumers, and the planet. Looking ahead to next year and beyond, the trend towards sustainability and transparency will press on. Ultimately, companies that take the extra steps to de-risk projects will be the ones setting a higher standard for industry and supply chain partners, building a pathway for long-term success.

On-Line Monitoring of Main Step-Up Transformers Pays Off for Large Solar Operator by John Eastman

Figure 1


hen entrepreneurial engineers began playing with the first microprocessors in the late 1970s, they sought out markets that could use autonomous systems to interpret data from outboard sensors, and report the conditions to stakeholders. The value proposition was the savings realized by replacing the process of manual testing with expensive test sets, and the staff of trained specialists performing the tests Figure 2: 12-channel bushing monitor (giving judgements on those results). system installed beside the transformer. Since the early days of Intel 8080 or Motorola 6800 processors, there have been many types of condition monitors aimed at the utility substation. Many have come and gone; most were less reliable than the equipment they were monitoring. Many of these had some merit, but, in the early days, communicating that data to stakeholders was not possible. The goal, even in the 1970s, was to communicate the answer– the distillation of the data – toward an action plan. However, the early monitors garnered no trust. They simply routed raw data to experts who were tasked with reviewing it. Data management became a thorny issue; scanning through data produced by monitors by asset SMEs quickly became impossible, especially in light of the layoffs and downsizing happening at the time. Add to this problem the short lifespan of the early monitors, and the many companies that produced them, and it’s clear why the concepts never reached a full potential of usefulness. The goal for on-line monitoring was to give an actionable signal that an asset was in trouble, with a time margin to intervene and prevent a failure. Continually serving up data for a “panel of experts”, to then give a recommendation on the condition of an asset, was never the value proposition. The early adopters of monitoring quickly learned that monitoring systems do not immediately reduce the maintenance budget. In fact, the reverse was true. Monitoring quickly identifies the “bad actors”, so they could be moved up the list for service. Only after the emergent assets were repaired and tested would the O&M expenses gradually decrease. Maintenance managers discovered a “sweet spot”, where deployed monitoring and regular manual testing worked together to produce a lower Figure 3: Precision-engineered bushing sensors installed on the C1 bushing test taps. overall minimum cost. With the refinement of the monitoring system over decades, many renewable energy installations (and utilities in general) have moved to nearly full reliance of on-line condition monitoring, thereby making the total expense only the depreciated cost of the monitoring system. The reality of the reliable automatic system is that calendar-based maintenance is nearly gone. In May 2021, a bushing monitoring system was installed by factory field Figure 4: H1 bushing nameplate showing engineers on the main step-up power 0.47% power factor rating.

transformer at a large solar installation in Imperial County, California. For this system, six signals from the transformer bushing C1 test taps were given by bushing sensors, three low-side voltage signals were taken from PTs, and three high-side voltage signals were taken from CCVTs. The use of all twelve Figure 5: Measurements, in percent, plotted from day of phasor measurements installation to mid-August, 2021. resulted in an extremely robust system with very high signal-to-noise ratio. By using measured system phasor quantities, the bushing attributes can be very accurately known. Within a few days, it was quite apparent there was a problem with the H1 high side bushing, with power factor nearing three times nameplate (Figure 4). Phase H2 and H3 showed stable power factor, essentially at nameplate values. Because of the heavy load cycle, this transformer was classified as being applied to “rough service”. The high power factor reading put it beyond the limit for any “watch list”, but was classified as “unstable”, and in danger of failure. The bushing was tested with off-line techniques, which confirmed the high power factor of H1. Plots of bushing capacitance and high side imbalance current were stable since the monitor installation, showing the likelihood that the H1 bushing had high power factor when the transformer was commissioned. With a spare transformer being located 1,800 miles away, a transformer replacement would take at least four weeks. The lost revenue during this time would be ten times the value of the transformer. The operator of the solar farm prudently replaced the H1 bushing during a nighttime outage, with no loss of revenue, likely saving the cost and lost revenue of a catastrophic failure. Scheduling the repair work during the night time hours would not affect revenue. Given the excellent performance history of over 700 bushing monitors installed within the parent utility, trusting the guidance of the monitor toward the prompt bushing replacement was an easy decision.

Smart Home and Building Automation by Magnus Asbo

No matter how much a home or commercial building is able to reduce its energy requirements, it is nearly impossible to completely eliminate energy demand. However, with solar, the building can become its own energy generator

As the world is moving towards sustainability and energy independence, so too is building architecture. As architecture begins to change to incorporate these values, we are more frequently seeing net-zero buildings and green building rating systems, such as Leadership in Energy and Environmental Design (LEED). In parallel, commercial buildings and homes are becoming smarter. This has opened the way towards managing energy in a more efficient manner. One of the ways to better manage energy is to design buildings that require less of it. For example, using passive ventilation techniques, passive solar energy, double/ triple pane glass, and thermal mass material to help reduce (and possibly eliminate) the requirement for HVAC units. There are many other areas in which designs can decrease the energy requirements of a building, including energy-efficient lighting, passive lighting, water conservation, and more. Yet, no matter how much a home or a commercial building is able to reduce its energy requirements, it is nearly impossible

to completely eliminate energy demand. However, the building itself can become its own energy generator. One of the most promising aspects of solar energy, versus other types of renewable energy, is that it is designed to be a distributed power source. Almost anybody with a roof has the potential to install their very own energy generation system, truly placing power into the hands of the people. For commercial buildings and homes with large rooftops, adding a photovoltaic (PV) system can be an excellent way to produce the amount of energy that is consumed on site.

Excess PV energy generated during the day can be stored in a battery, to be used in place of electricity from the grid during the evening, when tariff charges are typically higher. Shifting energy consumption is another form of energy management that can increase selfconsumption. This technique combines the technology of smart buildings with PV energy. By merging these two technologies, smart energy management solutions can automatically use a PV system’s excess power to increase solar energy usage, help lower electricity bills, increase energy independence, and provide greater convenience. Devices and appliances such as immersion heaters, lighting, fans, and pool pumps, can be controlled by smart energy management solutions (including AC switches with a meter, plug-in sockets with a meter, and dry contact switches). With the immersion heater, excess PV energy can be directed towards water heating, which is a lowcost form of energy storage. While the other devices allow appliances – pool pumps, fans, cold-storage, thermostats, and lighting – to be remotely controlled and utilized during high PV production for increased self-consumption. In addition to increasing energy independence, smart energy management allows for a simple user experience, especially when combined into one integrated energy management and monitoring platform. This enables a more streamlined smart energy and building management process to reduce operation and maintenance costs. As the technology advances, we will continue to see more opportunities to further integrate it into making buildings more energy efficient, like weather and irradiance forecasting integrated into energy management systems to help ensure more efficient planning of building heating, or personalized profiles and thermostat controls that can help increase comfort without additional resources. Combining these types of technology with architectural designs can help our buildings exist in better harmony within their surroundings and environment.

Adding solar energy to a building’s energy mix is a crucial aspect in making a building more energy independent, but it’s only the first step. The next step is improving the management of that energy in order to increase self-consumption. This is because energy usage does not always align with the energy generation of a PV system. As such, there are two ways that the energy can be managed to overcome this inconsistency. The first technique is energy storage, and the second is consumption shifting. Energy storage is an essential part of smart energy management; it stores energy when it is produced for consumption at a later time, instead of either limiting energy production, or feeding it back into the grid. With PV+storage systems, the inverter is responsible for managing battery charge and discharge patterns to meet consumption needs, and reduce the amount of power purchased from the grid. For example, in time-of-use (TOU) markets like California, energy storage can protect consumers from higher rates during peak periods, when PV systems are likely to be producing little or no

Solar Roundup by Brad Hise


n response to climate change and the need for renewable energy sources, construction specialists are finding that a growing number of clients are diversifying into alternative options such as solar, hydroelectric, bioenergy, wind, and geothermal technologies. Solar power is currently the most established of all the low-carbon technologies. Many facilities are capable of generating double- and even triple-digit megawatts of power, enough to power entire communities. The Solar Energy Industries Association recently set a goal for the U.S. to generate 30 percent of its energy via solar power by 2030. It’s an ambitious goal not too far out of reach, as solar facilities currently account for 46 percent of all new energy generating capacity in the U.S. In fact, the U.S. is currently ranked second worldwide for largest installed solar energy systems, with 3,322,162 solar power systems in place. These systems help drastically reduce the United States’ carbon footprint and create enough power for 23.3 million households. With this carbon emission reduction, 136 million metric tons of CO2 emissions are prevented, the equivalent to removing 30 million vehicles off the road, saving 15 billion gallons of gas. A large part of these efforts is due to state mandates such as renewable portfolio standards (RPS), which require energy retailers in the U.S. to supply a certain percentage of electricity from renewable sources. As a result, many utilities companies are investing in sustainable energy solutions, and working on developing strategies to reduce their environmental impact.

Lift modules safely and quickly

The Solmetric Module Lift safely and quickly transports PV modules to a roof. No motors, lightweight, and sets up by one person in 5 minutes. It uses an existing fiberglass Werner or Louisville extension ladder. A pulley system attaches to the top of the ladder. A patented module "hook" secures the edge of a PV module frame and prevents lateral sliding of the module. An operator pulls the rope to raise the module. The module slides along the outward facing surface of the ladder rails. "Ramps" allow the module to slide over any discontinuities in the ladder surface (e.g. the step between sections in the ladder). The pulley assembly includes a brake that prevents the module from sliding back down the ladder in case the bottom operator releases the rope too soon. An operator at the top removes the module and releases the brake to lower the hook. The Solmetric Module Lift enables OSHA compliance.

Renewable solar energy uses the sun’s radiant heat and light to generate power that is naturally replenished and inexhaustible. Solar power is sourced through photovoltaic (PV) solar panels containing small PV cells made of semi-conductive materials that are installed in large, decentralized, ground-mounted installations, creating utility scale solar farms across the country. These PV modules use a range of technologies to harness the sun’s power, changing sunlight directly into electricity, generating voltage, and creating the ability of matter to emit electrons when bathed in light: known as the “photovoltaic effect”. Energy is created when cells are created from semiconductor materials; the sun’s rays hit the cells and loosen electrons from the atoms. The electrons then flow through the cells, creating electricity. Once the energy is converted to electricity, it’s distributed to the power grid on high-voltage lines for distribution and consumption. Benefits of solar power are plenty, but the most well-known is reduction in greenhouse gas emissions. Energy from the sun reduces dependencies on coal and electricity, thus reducing CO2 emissions. Greenhouse gasses are known to trap heat and warm the planet, contributing to the greenhouse effect. This can increase temperatures and affect atmospheric composition. As a clean and renewable energy source (without relying on fossil fuels or other sources), solar power reduces these CO2 emissions. The International Energy Agency (IEA) states that solar power is tracking to set records for new global developments each year after 2022, with 125 GW new capacity average expected globally between 2021 and 2025. The goal is to continue toward this great reduction and, ideally, net zero emissions by the year 2050. Significant world goals and emission reduction in line with the Paris Agreement are greatly spurring solar growth and capacity. According to the UN, solar trends are predicted to continue at staggering rates, serving not only as renewable energy sources, but also contributing to growing segments of global energy production. Almost half of emissions cuts must be in place by 2030 in order to create a lower carbon economy, and keep global warming below 1.5°C. This huge milestone cannot happen if fossil fuel production doesn’t decline by approximately six percent per year between now and 2030. We’ve seen the cost of solar energy generation fall dramatically over the past few years. Solar industry cost-reduction roadmaps and technological innovations will create higher-efficiency modules, further reducing the cost of materials, and positioning solar energy as unbeatable when compared to fossil fuels. After all, this positive impact on the environment and climate change is the future we hope to achieve.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE, using a new antireflection coating, have successfully increased the efficiency of the best four-junction solar cell to date from 46.1 to 47.6% at a concentration of 665 suns. The layer structure of the new solar cell was developed back in 2016 together with the French company Soitec Inc., that designs and manufactures semiconductor materials. The upper tandem solar cell is made of gallium indium phosphide (GaInP) and aluminum gallium arsenide (AlGaAs), which was bonded by Soitec onto a lower tandem solar cell made of gallium indium arsenide phosphide (GaInAsP) and gallium indium arsenide (GaInAs). Now an improved contact layer and a 4-layer antireflection coating were applied to the tandem cell structure in Fraunhofer ISE’s Center for High Efficiency Solar Cells. These measures reduce the resistance losses and the reflection on the front side of the cell, which is spectrally sensitive within a broad range of 300 and 1780 nanometers.

Wind Energy Drives Sustainability in Canada by Jeff Chernish


n recent years, a number of initiatives, both public and private, have been taken around the world to promote the reduction of greenhouse gas emissions and achieve better environmental conditions. The recent COP26 highlighted the need for governments around the world to take immediate and effective action to limit harmful emissions, and meet the targets set in the Paris Agreement, which includes reducing global warming by 1.5 degrees. Canada is no stranger to this need, with more and more of its citizens calling for greater use of clean energy in their daily lives. Canada is currently one of the world leaders in the production and use of energy from renewable sources, which now account for approximately 19 percent of all energy supplied. The demand for this energy has also been growing exponentially. In 2009, renewable energies accounted for only 1 percent of all national consumption; by the end of 2020, this figure had already increased sixfold. One of the most relevant sources in Canada, and probably the one with the lowest operating costs, is wind energy. It is an energy whose production does not generate emissions, does not produce waste in local waters, and allows energy to be stored effectively and efficiently so that it can be used on demand. Thanks to our country's orography, the number of onshore wind farms has continued to grow over the last few years; Canada is the ninth largest producer in the world, with approximately 14,300 MW at the end of 2021 (according to data from the Canadian Renewable Energy Association), compared to the 13,413 MW produced in 2019. Thus, regions such as Ontario, Alberta, and New Brunswick already account for most of the facilities needed to produce and store the energy generated. These regions benefit financially, not only through the taxes collected by municipalities and local authorities for their presence, and by paying rent for the land on which they are installed, but also thanks to the generation of thousands of jobs in local communities. The fact that the number of wind farms continues to grow is also a major boost to construction. Each of these wind farms requires foundation work, transport of the wind turbines (from where they are manufactured, to their subsequent hoisting), and placement in their final location. For these tasks, a prior study of the land where each of the wind turbines will be located is essential to ensure the viability of the installation. This also helps to maximize precision in the transport. Due to the magnitude of the infrastructure, specialized and purpose-built trailers and transporters are usually used to move these delicate components, often over distances of hundreds of kilometers. One of the most delicate moments of the installation is when the wind turbine is lifted. Faced with multiple physical and environmental challenges,

lifting the load is a challenge for the engineering teams; they have to use mobile cranes with longer than usual booms to lift loads of several tonnes, and up to 150 metres high, with the utmost precision. Overcoming all kinds of obstacles, such as travelling long distances, ensuring that the crane is stable enough to start the process, and positioning the wind turbine, are just some of the challenges that teams of wind farm installation experts have to face dozens or hundreds of times, depending on the scale of the wind farm.

Offshore wind energy as a new sustainable alternative

As a complement to wind farms built on land, recent alternatives have appeared in the coastal waters of countries around the world, to harness the power of the wind flows that occur in these areas. While Canada has not yet made use of this type of offshore wind farm, by the end of 2020, there were already 31 projects for their installation that should be operational in the second half of this year. As with onshore wind farms, these installations pose significant challenges. The first, and perhaps most complicated, is the need to connect the entire generation infrastructure to the grid, which is usually quite far from coastal areas. The installation and transport of the equipment is also a challenge, as it is necessary to load each wind turbine on barges, sometimes self-submersible, to facilitate the task. Then, each piece of equipment is either attached to the seabed (it is important to assess the depth of the water for this), or installed on floating structures; these tend to be more respectful of the seabed and ecosystem, and allow for faster and more efficient installation and dismantling. Regardless of the type of installation - offshore, onshore, or floating offshore all of this equipment requires frequent maintenance. Having the equipment and expertise to carry out that work, and only interrupting the operation of each unit for as long as necessary, can be an important competitive advantage. Now is the time to act. Only with a strong commitment to wind power generation will Canada be able to stay ahead of the environmental targets that are essential for the coming years. This will require the commitment of all of us – companies, institutions, and individuals.

Cracking Under Stress What causes blade bearing cracks and where to find them before it’s too late Photographer: Carsten Selak

by Cory Mittleider

Inspection of cracked bearings Pitch bearings, also known as blade bearings, connect the wind turbine blade root to Once the cracked face is exposed, it is easy the turbine rotor hub. The blade bearings allow the blade position to be optimized at to see the beach marks, which are a classic various stages of operation. This includes optimized angle of attack to control drivetrain indicator of fatigue driven by load cycling. These beach marks can be traced back to a load, usually to maximize output. In other words, properly functioning pitch bearings central point (Figure 4). This central point are critical to maximize productivity of wind tubine generators (WTGs). is the initiation point of the crack. In recent years, the occurrence of cracking rings on blade bearings has been increasing. In our efforts to understand what is causing this problem we have inspected many failed bearings, as well as discussed with operators, consultants, and manufacturers worldwide.

Root causes of cracking rings

At the core of the failure is the combination Figure 1 of bearing design and the structure it is attached to. The bearing consists of 2 rows of balls with a 45 degree preloaded contact angle. When a moment load is applied to this bearing, from either aerodynamic thrust load or gravity bending, the 45-degree contact angle resolves these forces into axial and radial components (Figure 1). The roller and raceway system is capable of carrying these loads, but requires an attached structure that can resist substantial deformation of the bearing from this loading. If the bearing is allowed to deform, it will no longer be able to live its full intended service life.

Figure 2

When this bearing type is highly loaded in a pitch application, the highest stress concentration occurs within the bolt holes on the outer ring, just behind the outboard raceway (Figure 2). When the bearing is allowed to deform under load (Figure 3), this emphasizes this stress concentration.

Figure 3


The blade bearing application in a wind turbine accumulates load cycles quickly. A turbine that turns 12rpm, will rotate 17,280 revolutions every day, 24/7. Every time a blade goes through the 12 o’clock and 6 o’clock positions, the gravity bending moment changes direction (2 times per revolution). The blade bearings on this turbine could accumulate up to 34,560 cycles per day, and up to 12.6 million cycles per year!

In all the inspections we have performed on cracked bearings, this initiation point has been found in the same place: in the bolt hole, just behind the blade side raceway. This is the same place that we already know will have the highest concentration of stress. In the early days of the wind industry, there were some applications and some sites with cracking failures, but they remained somewhat isolated; they were largely attributed to poor protection of the bolt holes, combined with long transportation or laydown periods. This allowed corrosion to form inside of the bolt holes, further exacerbating the stress concentration described above. These were addressed with better care and corrosion protection during production. In the last few years, we have seen the cracking ring failure mode start to increase, especially on turbines with 100m and larger rotor diameters. In some cases, corrosion pits as small as 250µm are found at the initiation point. We have also torn down bearings that had corrosion protection, but still failed from cracking. Bearings failing with corrosion protection in the bolt holes confirms that, although corrosion can accelerate the failure, it can happen without a corrosion pit. When these bearings are replaced, this problem Figure 4

can be solved with upgraded bearings. For operators of these turbines, it is important to identify cracks early.

A cracked bearing is only the beginning

Once the crack starts in a blade bearing, there is no stopping it. The crack will continue to propagate from initiation point outward, and is known to lead to failing hardware (Figure 5), and even cracks in the hub. Additionally, one of the cracked bearings torn down and inspected had a second crack that was already approximately ¼ of the way through the cross-section, on the opposite side of the primary crack (Figure 6). It is critical to the safety of personnel working in and near the turbine that cracked blade bearings be identified early, and shutdown, before additional damage to equipment puts their safety at risk. It is hard to predict the rate at which a crack will grow – if a crack is found, the turbine should be removed from service immediately. The eventual failure mode of a cracked bearing is the blade falling from the turbine.

Where to look for cracks

Because the cracks initiate in the outer ring bolt hole, just behind the blade side raceway, and grow in a circular pattern (Seen previously in figure 4), the first external area where a crack should become visible will be next to the seal, just inside of the mounting hardware (Figure 7). Around the circumference of the bearing, there are multiple areas where cracks tend to form. The most obvious place to look is near sudden changes in system stiffness, such as lifting plates or stiffening plates (figure 8). These plates create a stiffness joint, leading to additional concentration of stress; the bolt hole just outboard of the plate is often a cracking point. We have also seen cracks form near hub entry ports, and other areas without obvious attachments to the bearing that change the structural stiffness of the hub. Cracks through the filling plugs (Figure 9) are also known to happen. These manifest slightly differently than the cracks found through bolt holes, but ultimately have the same consequences, and need to be addressed immediately when found.

Digitizing the Grid Keeping renewable energy on track by Gabriel Prado


enewable energy is on track to help meet climate targets, but there's a catch: The energy transition depends on getting more renewables on the grid, faster. According to current estimates, a digital version of the power grid can reduce the time for analyzing new connections by 50 percent or more. There’s no doubt that renewables are on the rise. According to the International Energy Agency (IEA1), this clean and green energy will likely overtake fossil fuels as the primary source of electricity by 2026. It’s all according to plan, as growing incentives, government regulation, global pressure, and public activism move the world in a planet-saving direction. But generating enough renewables to power an electricity-hungry world is only half the equation. We also need power grids that are ready to handle it.

Renewables developers queue up for connection

Imagine, for a minute, the changing demands on the grid. In a fossil-filled world, there were fewer providers and fewer sources of electricity that needed to be connected. Now, with a bounty of incentives ready for the taking, renewable energy developers are cropping up around the world. We need all of them if we are going to achieve this monumental transition. But there are two factors keeping the grid from being able to absorb, transmit, and deliver this clean energy. First, the grid faces challenges with having enough transmission capacity built out to properly distribute the energy from these new distributed energy resources (DERs). Secondly, the sheer volume of requests to connect to the grid these days has resulted in significant gridlock when it comes to approving new connections. While the ultimate fix here – building more transmission capacity – is a long term plan, we can focus on the shorter-term opportunities to integrate more renewables today at the existing capacity. Unless we can ease this gridlock, we may not see the use of renewable energy required in time to hit our climate targets.

Smarter analysis of the power system is required Let’s first get at the root of what’s causing this gridlock for grid operators. Take the national Transmission System Operator (TSO) in Norway, for example. They have experienced a significant increase in applications to connect to the grid over the last five to ten years. On top of that, their existing infrastructure, like


2022 JULY• AUGUST ///

that of many other grid operators, is aging. Recognizing this, the Norwegian TSO set their sights on finding a fix through more efficient analyses of their power system, which they believe would ultimately lead to faster decision time on the connection requests. Processing an application to connect to the grid can take at least several weeks to the better part of a year. It requires complex analysis to understand how this new connection will impact the grid, and to identify if additional infrastructure is required to reliably deliver the power. A team of analysts would typically be tasked to answer these questions, leaving it in their very human hands to make the final decision – thus, the gridlock begins to grow. Employing more humans, or creating around-the-clock work shifts, isn’t the answer to this problem either, as the amount of renewables developers seeking connection will only increase. Instead, grid operators need to create an environment in which the analysis can be conducted in a faster and smarter way. But there is so much data! And it’s sitting in various silos, in a wide variety of formats, going back years and years. Seeing the bigger picture when the data is so scattered is a tedious process that makes the analysts’ job a time drain.

A centralized data source is key to quicker analysis

The first step to solving this problem is to make all the data available in one place. Once it is centralized, made relevant through contextualization, and monitored for quality, it becomes a digital twin of the entire operation. This is a game changer for the analysts. Now they can access a single source of information to get everything they need to perform the analysis and make a decision. Grid operators that centralize their data in the form of a digital twin save as much as 50-70 percent of their time, as they no longer search multiple sources and structure the data themselves. Redundancy is also reduced, as once the data objects have been modeled and contextualized, they can be reused by another analyst. This translates into a meaningful amount of

time saved for far faster processing of new connection applications. The Norwegian TSO confirmed that being able to process these applications faster had significant and direct social impact. They aim to encourage new entrants to the power market, and believe that bringing these customers to the grid far faster is critical to ensuring a stable supply of renewable power for the market.

Let’s not let our grids fall behind

Data is also essential to helping us understand the current state of the grid. According to a recent investigative piece, the American grid is in desperate need of a trillion-dollar overhaul. This so-called “antiquated” infrastructure stands as the biggest threat to the U.S. making the transition to clean energy, as adoption of renewable energy depends on its reliability. And blackouts certainly won’t help the clean energy cause. This challenge can be alleviated, in part, with better insight into the current infrastructure. A central source of data can lead to making better connections in the grid, and it can identify the areas of investment so that money is spent where it’s needed most critically. The bottleneck we see now in the U.S. is the result of the influx of renewable sources coupled with the challenges related to sending that power where it’s needed. Unless we get the full picture of both the opportunities and shortcomings of our grids as they are now, we're likely to end up with a lot of wasted energy.

Demands on grid operators won’t disappear

Data is the best defense. The growth in the number of renewable energy business cases is a positive sign of momentum for our energy transition. If connection gridlock keeps these new entrants off the grid for too long, however, some of these important business cases may disappear. That will be the sign that things won’t be going according to our climate plan anymore. The burden on the grid operators will continue to be great during this critical period, but the data is ready and waiting to help reduce the load and ensure that the infrastructure – aging and all – is being used as optimally as it can be before any further investment is made.

Monitoring Wind 4.0

Latest technology for turbines by Richard Harada

Figure 1: Access to the nacelle requires special training and equipment.

Maintenance Challenges

As the percentage of wind power generation increases, the level of importance in maintaining these systems grows. Many of the conventional assets such as generators, transformers, and breakers are used for wind applications - but on a totally different scale, and located in a moving nacelle, on a tower, 100m off the ground. The maintenance techniques for wind generation are evolving as the technology matures.

Wind farms are usually in remote locations, requiring extra time and logistics to get to sites with the proper equipment. Offshore windfarms are even more challenging; they require more planning, training, and transportation to reach the site. Once at a windfarm, it takes additional time and physical exertion just to access the equipment inside the nacelle. Wind turbines inspections are much more complicated when compared to the inspection of land-based substation equipment; and require specially trained wind turbine technicians. In the US, a medium-sized windfarm will have 50 to 100 turbines per site. Inspecting each turbine manually can take days, or even weeks. In addition, the fact that wind turbines are shut down during the inspection means that electrical issues that occur under load will not be detected. With these challenges in mind, wind farm operators recognize the value of online condition monitoring.1 Through automated and early detection of anomalies, condition-based maintenance can prevent serious failures, allowing operators to optimize resources and reduce repair costs.

Technology to Overcome Challenges

Some utilities are implementing the same technologies that are driving the fourth industrial revolution in the manufacturing sector. The Industrial Internet of Things, (IIoT), machine learning, and cloud computing are among the new technologies that are already being used by electric companies for asset monitoring, predictive maintenance2, and the operations of distributed energy resources3 (DER). Industry experts have started calling this trend “Energy 4.0,” to highlight the magnitude of the transformation they expect it will bring to the electric industry. Energy 4.0 technologies can provide the tools utilities need to adapt to this new industry environment, and move to a greater adoption of these technologies by the electric industry.

Monitoring the Wind Turbine with Thermal Imaging

Thermal imaging sensors measure the infrared radiation from an object and convert it into a temperature value. An important feature of thermal imaging is that it is ‘non-invasive’; it uses a sensor that can measure temperatures without physically touching the object. Therefore, outages are not required to install the sensor or make the temperature measurements. Thermal imaging is commonly used in electrical applications to detect faults in connection points, switches, bushings, transformers, generators, and motors. Thermal sensors can also detect excessive heat due to friction in the bearings of the generator, gearbox, or motors that control the positioning of the turbine components. An advantage of thermal imaging is that a single sensor can monitor a variety of different pieces of equipment, instead of having separate, specialized sensors for each. Thermal asset monitoring can be used to track temperature fluctuation over the course of a day, a week, and even seasonally to monitor if there is a trend in the asset temperature that could be an indicator of an impending problem. Automated and continuous thermal monitoring can also provide measurements during changing environmental and load conditions, as well as provide the data directly to operators, SCADA, and asset management systems. With the advancement of IoT and infrared technology, the two are now able to be combined onto a single sensor. This brings thermal imaging into the IoT world, and makes the technology and associated data much more accessible and cost effective.

Work confidently in hazardous environments

Figure 2: Electrical and mechanical systems inside the nacelle can be monitored with infrared sensors.

Monitoring Inside the Nacelle with IoT Sensors

An IoT sensor with onboard thermal and visual imagers, and built-in wireless communications, is an ideal solution for monitoring inside the nacelle. The sensor can take temperature readings on live systems, which will detect overheating bushings, cables, joints, and insulators – even in enclosed and confined spaces. Thermal sensors can also detect thermal anomalies in mechanical equipment such as motors, bearings, and the gearbox. Due to the small size and low power requirement of IoT sensors, they can be installed quickly using magnetic mounts to keep the units in place. The sensors take snapshots that give operators a visual and thermal view of the system, with analysis done on a continuous basis. A dashboard provides a comprehensive view of the data with graphs of the temperature points, as well as visual and thermal images. Alarm thresholds can be set in the dashboard to alert operators instantly if pre-set temperatures are exceeded. The data and alarms can be sent to SCADA or APM systems, allowing the utility to use the data in a condition-based maintenance program.

A wholly-new design in torque tools, the Snap-on Intrinsically Safe ControlTech Torque Wrenches are engineered and tested for operation in Class 1 Division 2 hazardous environments (where flammable gases, vapors, or liquids may potentially be present). Snap-on’s Intrinsically Safe ControlTech Torque Wrenches comply with key safety standards, including: IEC60079-0, IEC6007911, UL121201, and CAN/CSA C22.2 No. 213-17, UL 508 (Part One), and CAS C22.2 No. 14-13. Additionally, the wrenches’ custom-designed battery packs meet UL 2504 standards. Designed for repeated use, Intrinsically Safe ControlTech Torque Wrenches are accurate to +/- 2% clockwise, +/- 3% counterclockwise, providing instant data on the exact torque applied. Snap-on’s Intrinsically Safe ControlTech Torque Wrenches come with a selection of interchangeable ISO/IZO heads to handle a wide variety of torquing applications. The wrenches are also Bluetooth compatible, enabling users to record the torque and turn angle data in real time, and transfers data using Snap-on’s CONNECTORQ app for increase quality and traceability of their work.

Snap-on Industrial ///


Using IoT and thermal sensing technology will allow windfarm operators to perform remote inspections, with 24/7 monitoring on sites and equipment that would otherwise be difficult, costly, and time-consuming to inspect. The sensors provide remote visual and thermal imaging of equipment inside the nacelle. The IoT sensors can be installed quickly and easily due to their small and lightweight form factor, low voltage requirements, and built-in communications. Continuous thermal monitoring ultimately improves safety and reliability, while reducing operating and maintenance costs.

US Offshore Wind Ambitions Hinge on Supply Chain by Declan Slattery

Bold action comes from bold ambition, and ambitions don’t come much bolder than the United States’ plan to scale-up offshore wind capacity from 42 megawatts to 30 gigawatts by 2030. That goal will require windfarms across almost the entire coastline1. As yet, there are no commercial-scale offshore windfarms operational in the country.

This goal will require an unprecedented pace of development. The US is not allowing itself the luxury of the multi-decade timescales European pioneers like the UK have followed. That’s okay though, because the US is not starting from zero; it can build on the expertise and technology developed in Europe to accelerate the roll-out. After all, if any country has proven its ability to deliver on supersize projects, it’s America. How exactly then, can America incorporate the best of the European offshore wind industry to meet its ambitions? It helps to be specific, so let’s focus on supporting installation infrastructure and supply chains.

The Problem of Ports and Vessels

Installing and commissioning turbines offshore requires a variety of specialized vessels, ranging from wind turbine installation vessels (WTIVs) to jack-ups, crew transfer vessels, and cable laying vessels. These, in turn, rely on specialist port infrastructure shoreside to load, service, and deploy them. The US has a shortage of the necessary specialized2 vessels. An obvious solution would be to source them from elsewhere, but this avenue is restricted by the Jones Act, which prevents foreign-built, -owned, or -manned vessels from transporting goods between US ports, hindering the import of fleets from more mature markets. Although the first Jones Act-compliant WTIV wind farm service operations vessel3 is projected to be sea-ready by 2023, the tight timelines involved in installing 30GW by 2030 makes it unlikely that a new compliant vessel supply will suffice. Even if the order book balloons tomorrow, designing and commissioning such vessels is itself a multi-year undertaking. However, the challenge is surmountable. Indeed, the Jones Act has been in place since 1920; in that time, another offshore industry with similarly complex requirements has thrived – the Gulf of Mexico oil and gas sector. Possible workarounds include operating out of Canada for projects in the Northeast, or relying on US-flagged barges. The Jones Act applies from port-to-port, so components could, for example, be transported by barges from the shore to waiting WTIVs that have sailed from Europe or Asia. Such solutions come with ingrained inefficiency; they don’t obviate the need for investment in US specialist vessels, but they can make the short-term pain less acute.

Onshoring the Offshore Supply Chain

Currently, the US also lacks a fully-established domestic supply chain4 for offshore wind; relying on an internationally dispersed and disparate supply chain could also impede development. Capital projects worldwide – and not just in the offshore wind sector – are suffering from materials shortages at the time of this writing, and that problem is harder

In this context, it will be instructive to watch the progress of the 800MW Vineyard 1 project off the coast of Martha’s Vineyard – “a project that the industry has long treated as a harbinger of the industry’s fortunes5” and the first commercial scale offshore wind farm in the US. The US can benefit from Europe’s more mature offshore wind market, which has been able to join up everything from supply chains to design and engineering – both by sourcing services and components directly, and by looking to its development for instruction. If it can get the balance right, the nascent US offshore wind industry could become a tremendous source of jobs and wealth for the country, and even bring that lofty 30GW by 2030 target within reach.

– and more expensive – to manage when suppliers are extremely remote. As an added incentive to build out the domestic supply chain for the sector, local economies can be bolstered by local content and skilled employment opportunities. This is particularly important in the US, which takes pride in supporting a healthy ecosystem of independent service and equipment suppliers, such as those which are so prevalent in the Gulf of Mexico and in the onshore oil and gas sector. Fortunately, there are signs that elements of the US offshore wind supply chain are clicking into place. Homegrown giants and specialists have rich expertise earned abroad to bring to bear at home. Then there are other companies doing the reverse – taking expertise developed in far-flung home markets and applying it to the States. These not-so-newcomers have made strides in manufacturing subsea cables out of the US, with other major players poised to leverage expertise built in US onshore wind, US offshore oil and gas, and European offshore wind to move quickly in the space. This appears to be a winning combination – a balance of American companies supplying American projects, with specialists from abroad plugging the gaps and creating American jobs in the process. However, there is a significant stumbling block in this regard, as it can be difficult for foreign companies to know where to base their US operations. Different states apply different offshore licensing rules, employment law, taxes, and incentives, all of which creates a level of uncertainty; the day after you make a decision, another state may announce

an even better deal, leading to decision paralysis. In time, this problem will fade as different areas generate a critical mass of certain businesses and become the de facto centers of gravity for their respective niches – but time is of the essence, and an expedited solution would help maintain momentum.

All Eyes on Martha’s Vineyard

There is an urgent imperative to integrate and simplify buying services across a complex, far-flung international supply chain. US developers could benefit from neutral conveners capable of bringing together an ecosystem of equipment, and providing an integrated end-to-end offering from equipment sourcing to operation.

An operational must-have in the new global energy economy by Rob Budny


Light when you need it Aircraft Detection Lighting Systems

espite the raging pandemic, the global supply chain, and project construction disruptions, 2020 and 2021 were banner years for renewable energy. The global wind industry installations surged, as did solar photovoltaics, hydropower, and the pressing need for energy storage. Renewable power capacity rose to 290 gigawatts (GW) in 2021, outpacing net installations in fossil fuels and nuclear power combined. Although renewable energy is now considered a new global energy economy, there are still impediments to widespread adoption. Political pressures (which vary by country and sector), government regulations, and corporate influences are all issues outside the power of technology; high material costs, managing outdated infrastructure and asset failures, and cyber threats, however, are not. Artificial intelligence (AI) and machine learning (ML) have become revolutionary for renewables, unlocking the vast potential of renewable energy data, and transforming the industry. By leveraging the power of these technologies, power companies can accelerate production, predict and prescribe maintenance, maximize operational efficiency, and improve overall grid management operations.

As an example, commercial wind turbines carry a hefty price tag of $2.6 – $4 million per average-sized turbine. Operation and maintenance costs average $42,000 – $48,000 per year. This is a cost that climbs with the age of the turbine, mainly due to the harsh environments in which they operate. Wind turbines, along with all renewable energy assets, create a flood of data, especially when digitized. Turbines generate SCADA data, outputting values for up to 500 different metrics each second. Project operators are tasked with spending far too much time and too many resources sifting through this data. Without any technological assistance, they inevitably miss opportunities to optimize projects, identify and address underperforming assets, and prevent failures and downtime. Wind turbines are also complex mechanisms, comprised of more than 8,000 different components, including electronics, sensors, hydraulics, yaw motors, rotor blades, mechanical brakes, gearboxes, generators, and more. Failures of any of these can cause varying periods of downtime. Gearbox failures are rare, but cause an average of six days of downtime. Electrical damages are

more common, but the downtime duration is shorter, so wind technicians tend to focus on preventing failures that result in long periods of downtime (gearbox, generator, and drivetrain). After installation, the most complex and costly aspect of wind energy production is maintenance. Global onshore wind operations and maintenance costs reached nearly $15 billion in 20191. Of that amount, $8.5 billion was spent on unplanned repairs and corrective actions caused by component failures. Given the cost of hardware components and labor, wind power plants and asset owners have sharpened their focus on operational expenditures.

Using AI to reduce costs and improve performance

There are numerous ways artificial intelligence can be applied to renewable energy. In utilizing an AI-enabled asset management platform designed specifically for clean energy, owners can take advantage of the latest in cloud computing and data

analytics with AI and ML technologies. Comprehensive platforms, complete with dashboards, monitoring, automated reporting, alarm and event management, and natural language processing (NPL) of unstructured data, can significantly benefit and augment the operators who deploy them. Structured and unstructured data can be turned into predictive maintenance, production forecasting, energy optimization, parts forecasting, and data aggregation capabilities – in real-time, and with visualization and reporting. Combining the power of data analytics with physics-based digital twin technology results in comprehensive models with incredibly high accuracy and long lead prediction horizons. AI and ML can also be used to simplify the highly complex process of managing decentralized grids, and balancing supply and demand in real-time. Decentralized energy sources can send excess electricity to the grid, while utilities direct that power where it’s needed.

Fight technology with technology

Cyber threats are a serious challenge for the renewables industry. Many of the systems currently in use were built to prioritize efficiency over security, with original equipment manufacturers and third-party operations and maintenance providers granted open access to assets and networks. Each physical and online access site presents a possible intrusion point. The resulting gaps (technical, people, and process security) leave the entire renewables value chain vulnerable to malicious actors, disgruntled personnel, and/or nefarious third-party vendors. Cyber breaches on renewable assets have potentially severe consequences, including (but not limited to) loss of data, production, revenue, and reputation, as well as health, safety, and environmental risks. To mitigate threats, security must take priority; it must be assessed at every stage of the project lifecycle, with AI embedded in all processes. Bad actors (hacktivist groups, lone wolf hackers, and state-sponsored cyber warfare units) are becoming more sophisticated in their endeavors. They continuously devise new forms of cyberattacks like crypto-jacking and malware attacks on the Internet of Things, or smartphones and cross-site scripting. By leveraging machine learning, companies benefit from real-time monitoring and security threat detection, which can prompt quick action. Low-profile, cognitive endpoint agents learn the common behavioral patterns of devices so they can be analyzed to detect anomalies, without impacting user experiences. AI technologies prevent zero-day and polymorphic malware attacks, such as the malicious computer worm Stuxnet, the banking Trojan called Ursnif (also known as Gozi), Vobfus Windows worm virus, and Bagle, an email worm, as well as advance masking techniques like weaponized documents, scripts, macros, and memory injection attacks. There is no doubt that renewable energy is the solution to the climate challenge – fossil fuels are by far the largest contributor to global climate change, accounting for over 75 percent of global greenhouse gas emissions, and nearly 90 percent of all carbon dioxide emissions. But renewable energy powered by next-generation, endto-end AI technology is what will take renewables from a newsworthy buzzword to a sustainable and safer future, all while increasing automation and cost savings, digitizing maintenance, creating higher operational efficiencies, and improving our bottom lines.

Passive Oil Containment for New England’s Ocean Wind by Bill Gannon

A new permitted wind farm off the coast of Cape Cod, Massachusetts has been under construction since November of 2022. This project is located 35 miles from the coast. Consisting of 90 wind turbines, each 1 nautical mile apart from each other, it’s the first large wind farm off the coast of New England. It’s expected to produce electricity for 400,000 homes. This is a huge project with many environmental concerns, both at sea and on land. The power from the offshore substation will be brought onshore via cables buried below the ocean floor, which prevents disruptions from any outside source once the project is completed. The power cables will be brought into the mainland of Cape Cod, then trenched and buried for several miles to the two substations, where the power transformers will be located. Given Cape Cod’s reputation as a pristine area and vacationer’s paradise, years of research went into minimizing the environmental and aesthetic impact of this project. Only after all areas of concern were addressed would permitting be granted for construction to begin. Many engineering firms were involved in the earlier stages of the project. A main concern was how oil containment would be employed at the substations on Cape Cod. One method, called passive containment, involves no moving parts. This allows rainwater to flow through the filter media draining the containment pits. This innovative passive containment system allows for removal of oil sheen to non-detectable levels in rainstorms, while also providing 100 percent oil containment in the event of a total failure, by instantly shutting down all drainage in seconds. Cape Cod Massachusetts water supply is from the underground aquifers; preventing any contamination is vital. The benefits of passive filtration, along with limited maintenance, would safeguard the needs of Cape Cod and its sensitive aquafer. The passive technology can be demonstrated by having water flow through a media tube, then introducing transformer mineral oil. As the water level drops, the oil enters the tube and is absorbed into the media. The media dissolves on oil contact and tackifies, causing a solid seal in seconds. This passive approach also works on oil – contaminated water running through the filter to the point where any oil sheen is removed to non-detectable levels. Since 1999, this passive technology has been proven in the field to contain oil from both spills and transformer explosions with fire. No oil has ever been released. After years of planning, the first of two substations is finally under construction. This substation will have eight oil containment areas for 4 large power transformers, 2 shunt reactors, and several GSU transformers and capacitors – all requiring complete oil containment. Each containment area is sized for the

amount oil in each piece of equipment. The large transformers and shunt reactors contain up to 23,000 gallons of oil, and must have 110 percent containment. An additional free board of 30” remains for rainwater, while at the same time being able to drain the water. The containment areas are concrete, approximately 49' X 39' with a depth of 5'3" sloped toward the passive oil barrier. These barriers are manufactured using a 36" inside diameter High Density Polyethylene pipe (HDPE), 30" in height with a 4" lateral drain on the bottom floor of the HDPE housing. After the housing is installed, hooked up to drainage piping, backfilled, and with concrete poured around it, the area inside the containment must be thoroughly cleaned to remove all concrete dust and debris. The sumps are then covered until the barriers and dirt filter are installed. The picture below on the left shows the completed barrier, with the top hat filter resting on the black housing (as delivered). The canister is attached with stainless steel screws to the top flange on the housing. Lastly, the top hat filter attaches above the canister to filter dirt and debris before entering into the barrier canister. Each passive barrier has a flow rate of 50+ gallons per minute while continuously draining during a rain event. Passive filtration provided for oil containment is relatively maintenance free, provided the area is clean when installed. The top hat filter is the first stage of filtering, keeping most dirt and debris out of the barrier canister. The canister also has internal dirt filters that can be cleaned by removing the top grate; if dirty, the round 2" thick batting disk can be replaced. Because passive filtration oil containment does not require pumps or opening ball valves for drainage, it offers a major advantage regarding maintenance. Draining water from containment areas requires time taken away from other important jobs. Many containment areas can be overlooked, and not properly drained, which creates other problems like too much rainwater without the volume for oil, mosquito breeding, algae growth, or oil sheen. Passive filtration solves all these problems. Passive oil containment is used in thousands of applications, in many different forms. By allowing only clean water to be discharged, and sealing off in an oil or fuel spill, this technology has set a new standard for oil containment.

Ensuring the continual performance of renewable energy assets requires a systematic approach to maintenance, repair, and monitoring. In order to prepare a comprehensive maintenance plan, inspections must be performed to determine faults and failures, whether through sensing technology, photographic evidence, or human interface. Advances in technology are rapidly changing the way the industry conducts this business. The evolution of drones and artificial intelligence technology have developed into increasingly accurate methods of inspecting equipment, analyzing, and reporting generated data to produce actionable planning for scheduled maintenance, effective budgeting, and reducing urgent repairs.

Thermal Management Unlocks Safety, Dependability, Range, and Longevity for Commercial Electric Vehicles by Gina Bonini


umans have designed and built motorized vehicles for more than a century. Deciding which method of propulsion to use did not start as a question about environmental impact, but rather as a pragmatic tradeoff between technical feasibility, availability of the fuel source, and safety. Although electric vehicles (EVs) appeared as early as 1886, most models have been powered by the internal combustion engine (ICE). As the dominant choice for as long as anyone can remember, ICE-powered vehicle technology is mature, rarely presenting novel engineering challenges outside of making the technology cleaner. While more recent innovations such as alternative fuels, exhaust gas recirculation, hybrid drivetrains, and shut-downon-idle have helped reduce emissions, progress is increasingly marginal. As the transportation industry pivots its substantial engineering resources to EVs, the innovation cycle for EVs is only just accelerating. Today, EV propulsion, energy storage, and near-countless incomprehensibly complex microelectronics components are subject to a blinding pace of advancements, inventions, and breakthroughs. With this relentless pursuit of faster, safer, and more efficient technology, vehicle manufacturers don't face marginal engineering decisions, but near-revolutionary ones regularly. Commercial and specialty vehicle original equipment manufacturers (OEMs) are focused on bringing their all-electric vehicle platforms to market in time to meet strong demand, driven by corporate and government commitments to reducing emissions. States like Washington, for example, have moved to ban all ICE vehicles before 20301, leaving OEMs just eight short years in which to deliver all types of zero-emission commercial fleet vehicles. Furthermore, a growing number have stated their intentions to stop investing in new ICE platforms and models; many more have already defined a specific date to end ICE vehicle production. OEMs now face mounting resource constraints as they design, validate, and ramp production on an entirely new propulsion system – and decide which elements of EV powertrains and their supporting systems should be developed in-house, or outsourced. New electric platforms must meet the range, durability, and reliability required by the commercial vehicle market. Is it possible to spin up multiple new technology teams (software, chemical engineering, and semiconductors, to name a few) in-house in time to meet escalating customer demand? Similar to ICE engines, but different in profound ways, the impact of ambient operating temperature on electronic is significant. EVs are Integrated Energy Storage System components chock-full of power electronics and • Scale power & capacity independently with inverters & batteries batteries; thermal management (at both ends of the mercury) determines • Smart, easy to use app puts the power of an energy storage system (ESS) in the palm of your hand for total control & reliability vehicle longevity, performance, and safety.

Anyone who has ever tried to use a smartphone left on a car dashboard on a summer day, or overnight in winter, knows the impact of operating temperature on electronics. So do owners of hydrocarbon-powered cars in Arizona, or Minnesota. For EV owners, however, rather than simply waiting for the temperature extreme to pass (or in the worst case, swapping the battery, SIMPLIPHIPOWER.COM | 805-640-6700

heating the engine block, or refilling the radiator), their electronics and batteries are not limited to providing starting power or running vehicle accessories; they are the whole show. Commercial EVs, by definition, must be productive assets. Electronics and battery performance are essential to reliably generating value and getting the job done. Extreme heat and cold can significantly degrade electric powertrain performance, range, and longevity. More profoundly, a catastrophic thermal runaway in batteries (in severe cases) places thermal management at the heart of EV safety, beyond the operator's actions behind the wheel.

Thermal management in EVs is one of the least visible, but most cutting-edge frontiers in EV transportation. From dissipating heat generated during power conversion and electrochemical processes, to warming components up to the optimal operating range, the right temperature improves performance, longevity, and safety, and enhances battery charging speeds. While many of these issues are, for the most part, problems already solved in EV passenger cars, the inordinately larger workloads and duty cycles of commercial, purposebuilt, and off-highway EVs result in correspondingly higher voltages and battery capacities. When combined with the harsher operating conditions of these work vehicles, these technologies cannot simply be scaled up from the passenger car domain. Innovations in efficiently controlling temperatures of EV propulsion components are at the apex of making electrified commercial fleet vehicles viable. Similarly, and perhaps even more so, thermal management will be at the forefront as the industry moves again from EV technology to fuel cells. So, keep an eye on the thermostat in this space.

Gina Bonini is Vice President and General Manager of Advanced Thermal Systems at Modine, which designs, manufactures, and tests heat transfer products for a wide variety of applications and markets.

Software for Fleet Management Inflection point for EV success by Jon Leicester

The commercial fleet vehicle market is already substantial, accounting for 3.5 million annual vehicle sales in the U.S.1 – and it's growing in step with fleet operators' evolving operational and emissions needs. As clean fleet technology2 advances, fleet owners and operators are no longer faced with the challenge of electrifying existing vehicle pools. Still, they are focused on how to manage them at scale. Whether it's school buses shuffling kids to and from school, or box trucks dispatching packages, we all rely on transportation in myriad ways. Electric vehicles (EVs) are expected to carry out the same jobs as their Internal Combustion Engine (ICE) predecessors. Accomplishing the tasks demanded of EVs remains the primary goal for any fleet – electric or not. Fleet operators, therefore, must understand and master the many differences between running ICE vehicles and EVs. The management and operational dynamics of electricity-fueled vehicles start with a shift from focusing on hardware, to concentrating on software. ICE vehicles are dominated by moving parts, involving everything from conventional engine repair and maintenance intervals, to replacing fluids during a routine oil change. Conversely, EV hardware includes fewer moving parts; software is the core component. Everything from EV charging to energy management, including grid and utility interaction, represents an array of digital transactions and data flows, including realtime charger and vehicle operations data. These all rely on a software-driven connective fabric to work together. Chargers, vehicles, and software all must interact seamlessly for this to work. Fleet operators new to EVs find themselves pressured to 'spin up' electric fleets without a clear path to understanding how these new components function together, much less how to manage the entire ecosystem through new software. An integrated software platform that can provide in-depth analytics is essential to ensuring reliable and consistent operations and, ultimately, achieving their various missions. As a service-oriented business, fleet charging is a complex system that depends on a wide variety of players to generate value. Software can handle the added complexities of EV fueling, including monitoring charging station health, charge levels of vehicles,

and operators can view everything down to the lowest level of operation. They are able to control various aspects of their fleets, from dynamic power allocation that maximizes fleet readiness, to real-time energy consumption and lower total cost of ownership. By allowing fleets to manage energy, track charge time, and notify managers of potential problems through real-time alerts, software helps to repurpose their chargers for public consumption and more large-scale deployment; successful operation of EV fleets becomes possible. Acting as the digital connective tissue between vehicles, charging stations, telematics, and more, software is the key that unlocks fleet management. energy usage, and so on. An added layer of complexity comes into play when chargers and vehicles from multiple OEMs are deployed in the same environment. This is only compounded when integrated with the installed base of ICE-vehicle fleet management systems, whether off-the-shelf or internally developed. These systems generally encompass all aspects of fleet management, from fuel card data, maintenance reports, or driver assignments, and allow fleet managers to see their fleet's state easily. EV fleet management is no different. A fleet manager needs access to key operational data on fleet inventory, vehicle usage and status, maintenance levels, and more. Adding EV charging to the mix adds an extra layer of monitoring needs, but using multiple systems to get this information is not ideal. Adding EV charging management into the mix, and a modern, API-enabled system for EVs, should provide fleet managers with indepth information and analysis about their EV fleet ecosystem, without having to deploy new software or switch between multiple applications or platforms. Integration and real-time data exchange between EV systems and incumbent 'designed for ICE' fleet systems is essential to efficient EV fleet management. By offering a flexible, robust, and scalable API, software companies can help build EV modules into platforms that accept API function calls, making EV deployment much more straightforward. For fleet operators, this means utilizing telematics devices and platforms that promote fleet efficiency and up-time through the ability to monitor and communicate location, fuel consumption, driver behavior, and similar data. From a business perspective, these advanced capabilities transform how operators manage fleet vehicles by providing reliable operational data, which can then be leveraged to optimize charging schedules, and understand energy consumption and vehicle state of charge. With countless unique metrics, linking EVs with an intelligent route planning system gives drivers and operators the insights required to get the work done. The way we manage fleets is rapidly evolving. Whether operators are just starting to add EVs to their fleet, or managing several vehicles already deployed, having the foundational support of high-quality software is critical.

A New Look at Performance Monitoring for Energy Storage by Stefan Greens


erformance monitoring for the energy storage industry has traditionally meant a hodge podge of different systems, often based on outdated technologies and interfaces, with limited or no ability to communicate with other systems. This has led to a lack of trust in what, if any, insights are provided. A new look at performance monitoring in battery-based energy storage systems (BESS) brings a holistic, cloud-based approach that incorporates data from disparate systems and workflows into a single, value-based view. Before we talk about what this looks like and what value it adds, let’s first consider what “performance” really means. In the context of a battery energy storage system, “performance” is such a multifaceted term that it requires some organizing principle for it to become useful. Different stakeholders approach performance differently, since each has different optimization targets and timescales in which to reach them. Specifically: • Operators aim to optimize direct operational metrics, such as state of health and availability. • Utilities value maintaining grid stability and reliability, via applications for frequency and voltage regulation. • Owners aim to maximize financial metrics such as ROI, remaining useful life (RUL), and NPV. • Societies and their representative governments increasingly demand renewable energy, where reducing greenhouse gas emissions is the key success metric.

These success criteria are, for the most part, aligned with one another; but they also build on each other. With modern monitoring tools now able to capture, parameterize, store, and process data at scale in the cloud, a layered approach to generating successively more sophisticated and context-specific performance indicators from a foundation of directly sensed streaming data, in real time, becomes feasible. The approach, in effect, is to build a “value chain” for data. The levels of data build upon each other, like links in a chain, to provide increasingly sophisticated insights. The initial, most basic “link” in the data value chain is empirical data, captured in real time by sensors in the cells, strings, and energy blocks, and visualized directly as time series — for attributes such as voltage, current and temperature. The next link is derived metrics, directly enabled by the raw inputs. Calculating the maxima, minima, and distributions of voltages and temperatures across cells in a string or block provides a quick sense of balances (or imbalances) in the system. Various algorithmic models allow the accurate calculation of state of charge of a string as a live attribute, based on current and voltage. These outputs, when fed to a condition-action rules engine, can generate many of the alerts that an operator needs to monitor for events such as overheating, voltage imbalances, and downtime. The following link in the data value chain provides the data required for maintenance planning, where discrete data points for each charge and discharge cycle are calculated by collapsing the millions of live granular points into algorithmically derived metrics that characterize a battery’s state of health. These cyclic attributes include equivalent cycles, a measure of battery use, and indicators of battery health such as energy efficiency across a cycle and maximum capacity at top of charge, both of which degrade with aging. A number of links, or levels of data insight, exist beyond these initial three. Let’s talk about what those include. Firstly, while the data attributes we’ve already spoken about are sufficient for condition-based maintenance regimes, where individual batteries are replaced when they show sufficient performance degradation, machine-learning algorithms can go one better. By training them on the historical time series and cyclic data of individual serialized batteries, they can provide Remaining Useful Life (RUL) estimates or flag incipient anomalies, enabling predictive maintenance regimes that can dramatically cut downtime and costs. It’s always good to keep in mind that performance is, above all, a financial metric. Maximizing the ROI of a BESS means using its available cycles smartly. To accomplish this, we can link the existing value chain datasets with time series data sourced externally. For example, weather data subscriptions provide forecasts for temperature, humidity, cloud cover, and wind speed, while market data subscriptions provide dayahead energy prices. These external data sources can add an additional dimension to your dataset, driving new insights such as determining when to charge or discharge a BESS to maximize revenues for the cycle. A modern energy management system (EMS) can automate these decisions, locking in maximized cost savings.

While optimized charging cycles can have a positive impact, even smarter financial optimization is now possible with a modern performance monitoring solution. Purchasing power agreements, warranty agreements, and leasing arrangements are essentially codified rulesets for BESS operating envelopes, with penalties for transgressions and rewards for beneficial use patterns. A condition-action rules engine can ingest these rulesets as data, with verifiable proof of transgression events and automated score-keeping. It now becomes possible to pursue an operating regime where the occasional out-of-envelope event is justified, if the expected revenue gain outpaces the penalty. Conversely, with all this available data, it becomes possible to accurately model the Net Present Value (NPV) of a BESS when a leasing arrangement ends, or the asset is sold or held as collateral. Perhaps the most holistic — and freshest — measure of performance is a societal metric: How efficient is a BESS at reducing greenhouse emissions? Every kilowatt-hour of renewable energy provided by a BESS to the grid (because of peak shaving, curtailment avoidance, or price arbitrage) directly impacts the global cumulative carbon footprint. That number, in tons of CO2 equivalent, is calculable once we know how much the BESS is contributing to the energy mix of the local grid.

While a strategy of using a renewable energy BESS to avoid curtailment events at all costs is likely the most impactful in terms of reducing CO2 equivalent, this may not be the strategy that maximizes revenue. But since both strategies can be modeled from the abundance of data in the holistic data value chain, so can the revenue differential, which can form the basis for calculating governmental incentives to do the right thing. Modeling performance scenarios for a specific BESS based on its unique historical data, and then seeing how well the real-world equivalent matches its “digital twin” (and adjusting the model accordingly), puts us at the apex of the data value chain. A modern performance monitoring solution can derive a unique degradation curve for each and every battery under management – preferably down to the individual serial number – and calculated from the usage patterns and ambient conditions described above. The battery data value chain is an approach to analyzing battery data down to the individual serial number. Unlike fleet or system-wide metrics, serialized data threading allows for increasingly sophisticated analysis of an individual battery’s health and performance, with each level or “link” building on the one before it. Not only have the analytical insights grown increasingly more sophisticated as we’ve added link after link, they are, above all, more relevant and able to adapt to the specific optimization criteria of the stakeholder. A modern performance monitoring solution should be flexible enough to accommodate both these varying levels of criteria, as well as build a full data value chain based on the data you already have, no matter where it resides.

Clean Energy Storage in Synthetic Methane by Mark Pastore

Power-to-gas is a technology by which the energy of a power source is stored in the form of a gas. When power-to-gas is combined with methanation, a clean synthetic methane is produced from CO2 and hydrogen, which is a renewable and clean drop-in replacement for fossil natural gas. Power-to-gas methanation has many advantages, including efficient use of power that would otherwise be curtailed, long-term and high capacity (TWh) energy storage, and production of low carbon intensity (CI) fuel. This long-duration (weeks to months) energy storage cannot be accomplished with traditional batteries.

As an example of power-to-gas methanation, CO2 and clean hydrogen are combined by a microorganism, called ‘Archaea’, to produce clean, synthetic methane with a CI that is significantly lower than fossil natural gas. Thus, use of low CI synthetic methane significantly reduces GHG emissions, utilizes investment in existing gas distribution and storage infrastructure, and promotes full use of renewable generation assets, all while supporting the market for construction of new renewable resources. A two-step power-to-gas methanation process is illustrated in Figure 1.


Figure 1. (1) Renewable electricity is used to produce clean hydrogen by electrolysis, (2) hydrogen and carbon dioxide are delivered to the reactor (3) in which clean, synthetic methane is synthesized by the archaea. (4) Synthetic methane is prepared for grid injection or use.

Power-to-gas methanation technology makes it possible to store renewable energy and recycle CO2 in a costeffective way. This technology eliminates the temporal link between energy supply and demand, allowing efficient energy storage in methane. When renewable power is available but cannot be used immediately, the power must be curtailed. If this otherwise curtailed power is available to produce synthetic methane,

achieve 100 percent renewable electricity. The power-to-gas process can provide a perpetually sustainable fuel, stabilize economic returns for the developers of renewable power, and reduce the risks involved in the development of additional renewable generation assets.

Mark Pastore is Director of Sales and Business Development, North America at Electrochaea Corporation, which produces renewable methane at industrial scale that can be used to green the gas grid, continue to green the power grid, and recycle any source of CO2.

Electrochaea Corporation ///

Figure 2. An illustration of synthetic methane as a means to store renewable energy. the energy will not be lost; it can instead be stored in the gas infrastructure (Figure 2). This enables full use of renewable energy production, even in the absence of available consumers, which allows for the continued growth of the market for renewable electric power. Application of power-to-gas methanation produces clean methane that can be used for power generation in both combined cycle gas turbine baseload plants and gas turbine peaker plants.

Long-duration energy storage that outlasts traditional batteries Power-to-gas adds a critical and additional advantage to renewable energy generation by providing seasonal storage of renewable energy. Analogous in many ways to pumped hydro or other forms of gravity-based storage, power-to-gas methanation converts wasted power generation into synthetic methane for much later future use. In this way, the existing gas grid and connected storage facilities become the largest battery in the US, storing renewable energy for use later in the day, month, or even year. The US has the design capacity to store ~4,690 billion cubic feet of natural gas, which is equivalent to 1.37 billion MW; ~6,000 MW of battery storage capacity was planned for 2021. Thus, there is as much as 23,000 times the amount of storage in the natural gas infrastructure as in the 2021 battery storage capabilities. Unlike traditional battery technologies, the ‘state of charge’ of the gas grid is effectively insensitive to a charge/discharge cycle. The gas infrastructure would essentially never be full of renewable energy, and would not degrade its state of charge during storage. Using existing infrastructure reduces capital investment, technology risk, and land use concerns.

Accelerate development of renewable power generation assets

When stored in the existing natural gas reservoirs, clean, synthetic methane can provide reliability benefits to the power grid while providing renewable electricity. A renewable gas reserve enables continued use of current electricity generation assets to produce low CI electricity, maintaining jobs and existing infrastructure with known reliability and performance metrics. Developing a renewable gas transmission system for power ramping needs is critical. For example, the recently projected load ramps in California (in excess of 25,000 MW by 2030) are unlikely to be met by solar and wind alone, which cannot respond on demand. Increasing the intermittent renewable resources on the grid will exacerbate not only the ramping needs in the afternoon, but also the intermittency and curtailment issues seen throughout the day. The loss of renewable production for even short periods of time, due to weather conditions alone, could jeopardize the power grid in the absence of reliable, proven gas generations assets. A synergy exists in the coupling of the renewable power sector with renewable gas production. As intermittent renewable electricity generation increases, there will necessarily be greater curtailment of electricity generation. The power that is being curtailed could be stored in the synthetic methane molecule using power-to-gas processes. By providing a buyer for economically curtailed power, production of lowcost renewable gas is enabled, and lost revenues for the renewable power producers are recovered. In addition, clean fuels produced using power-to-gas processes are capable of providing very-long-duration storage. This can play a significant role in addressing the seasonal mismatch in supply and demand that makes it difficult to

Transformer Asset Tax Qualification in Renewable Energy Projects by Balram Ramamurthy

Renewable Energy projects have been blessed with tax credits. Tax credits are incentives provided for green energy by the federal government; certain qualifications must be met in order to receive them. Wind and solar projects, in particular, have benefited the most from these assets. The Solar investment tax credit (ITC) is a tax credit that can be claimed on federal corporate income taxes, for up to 30 percent of the cost of a solar photovoltaic (PV) system placed in service within the period specified. Other types of renewable energy are also eligible for the tax incentive, but are beyond the scope of this guidance. In December 2020, Congress passed an extension of the ITC, which provides 26 percent for systems commencing construction in 2020-2022, 22 percent for systems commencing construction in 2023, and 10 percent for systems commencing construction in 2024, or thereafter. Any PV system placed in service after 2025, regardless of when it commenced construction, can receive a maximum tax credit of 10 percent. A subsequent amendment extended the 26 percent eligibility up to 2022. For those in the wind industry, the Production Tax Credit (PTC) provides a tax credit per kilowatt-hour. This benefit follows a similar scale down and has a sunset similar to solar projects. While the Solar ITC and the Wind PTC differ in their treatment application, we’ll focus more on the qualification process using an asset like a Power Transformer. An important aspect referred to and evaluated is the “physical work of significant nature” commenced on the project site, or on project equipment at the

manufacturing factory. Physical work has to be “integral” to the project; preliminary activities on site (e.g., clearing the site, or building a fence or access road, do not count as “integral”). “Continuity safe harbor” is an important test of qualification, and is satisfied in reasonable ways rather than through the demonstration of real, continuous, and physical work.

Transformer equipment and renewable tax credits

Custom engineered, designed, and custom-manufactured transformers can help a project to qualify for a renewable tax credit. This begins when a Developer/Owner/ Operator is able to pin down specifications for custom transformers. They are designed to this spec and sought for approval by the transformer manufacturer. The manufacturer then identifies and proposes the custom engineered and designed components within the custom transformer; upon approval, it completes manufacture of these identified components before the end of the calendar year as required for tax qualification. This whole process – and the offering of a custom transformer for the renewable project – aims at offering support to the renewable energy industry. Some pioneering work was done to offer dual process models to qualify – a “Continuous Process” and a “Stop-Go NTP process” (NTP - Notice To Proceed) based model. While the “Continuous Process” model continues manufacture and assembly of the transformer (after the qualification ITC components are completed by the year end), the “Stop-Go NTP” model completes the ITC qualification components by end of the year, then stops to await an NTP; upon receiving NTP, it then goes on to complete the transformer. Given the uncertain commercial operation deadlines so typical of renewable projects, it’s important to factor in the storage, care, upkeep, and maintenance of the finished transformer until the site is ready to accept delivery. This 360-degree customer support helps qualify the transformer for the tax qualification under either of the two models, and is the reason many developers consider it an excellent proposal. TAX CREDIT QUALIFICATION MODELS FOR RENEWABLE WIND & SOLAR PROJECTS (POWER TRANSFORMER SCOPE) Developers covering a large number of projects have used these unique process The Conformance Regulation models to get qualified for tax credit under 2022 2023 & beyond both the ITC and PTC. Keep in mind that 2022 is the final year to take advantage of the extended 26 percent ITC credit for the tax sunset period ending 2025, for project completion. To guarantee you’re getting the Continuous Progress Model most bang for your buck, be sure to work with an industry professional experienced in making these tax credit projects qualify with transformers.
