DID YOU WATCH THE “PERSEVERANCE” ROVER LAND ON MARS?

That was quite a trip … launching last July and traveling 225 million miles in seven months. I barely had the patience to endure 7+ hour family road trips, and that was before car seats when I could freely climb over my sisters in the station wagon while trying to stave off crushing boredom - back when Jimmy Carter declared a national moratorium on speed so we could all save more gasoline cruising at a lethargic 55mph. Come to think of it, I bet a cross-country drive at 55mph today might just feel like 7 months, especially when you add in all of those stops along the way. It’s interesting that even with all of the gains we’ve made in fuel efficiency, whether you drive a traditional car or EV, you’re still going to have to stop and refuel/recharge to go the distance.

NASA’s latest success got me thinking about the future. Supposedly, we’re here – we’re living in a time when we all thought we’d be driving flying cars and taking quick jaunts to the moon. Except that we aren’t doing any of that. Our air is less polluted thanks to cleaner burning fuels, and we’re pushing ahead with green power, but we seem to have reached a plateau in how far we can go with our current energy recipe. No matter which course has been proposed, the one ingredient everyone keeps wanting to leave out is nuclear power.

At a time when people around the globe seem desperate to reduce the carbon footprint of humanity, watching the energy industry collectively disavow nuclear power is nothing short of mind boggling. Want to cut emissions? Nuclear power produces no emissions. None. Worried about the ever rapidly accumulating piles of junk from discarded wind turbines and aging solar panels? We’re working on building recycling programs for all of the debris, but it’ll be a major challenge to keep pace. On the other hand, a nuclear power plant operating for your entire life only generates enough waste to fill a jar that could fit on your desk. Not that you’d want to leave it there, considering the danger. But that, too, has changed: A team of scientists has figured out how to recycle that waste. According to Johnathan Burns, a research scientist in the Texas A&M Engineering Experiment Station's Nuclear Engineering and Science Center, "In addition to addressing the fuel recycling problem and reducing proliferation risk, our strategy will drastically reduce nuclear waste to just the fission products whose radioactivity is hundreds rather than hundreds of thousands of years."1 Is the idea of nuclear still too scary? Does it evoke images of post-apocalyptic landscapes and irradiated giant reptiles destroying Japanese cities? Hollywood made millions preying on that post-war fear, drawing us in with movies starring 50-foot-men and visits from condescending aliens telling us we were too stupid and violent to handle advanced technology. In essence, we were brain washed. Only with the arrival of Star Trek and then Star Wars did nuclear power reclaim some of its awe-inspiring standing with the general populace.

Surprisingly, I had to dig through a lot of media materials on the NASA website to find a single mention of any nuclear power involved in the Perseverance rover project. Which begs the question: Why aren’t we celebrating this aspect of such an incredible achievement? Look at how amazing humans are – we managed to propel a 2260-pound vehicle through space to another planet 225 million miles away, land it on that planet, and make sure it generates enough energy to keep up a steady dialogue with us as it handily operates in temperatures below -100°F (far colder than Dallas in February, but the rover never lost power).

And yet, the Perseverance would never have left our atmosphere without being strapped to a combustion engine loaded with kerosene and liquid oxygen, after which solar power moved it through millions of miles of space, and now nuclear helps it toddle along the Martian surface, sending us beautifully detailed vistas from our sister planet. If some of the smartest people in the world understand the value in applying many different technologies to complete a successful mission, why don’t we?

Nuclear power is inextricably linked to the advancement of our life on and beyond this Earth. While we’ve made great leaps in taking advantage of all this planet has to offer, and continue to use our available resources responsibly, we would be unwise to throw the baby out with the bathwater; rather than shutting down nuclear facilities in the name of progress, we may want to take a page from NASA’s playbook, and continue to learn and educate ourselves about one of the most brilliant discoveries in human history.

Ultra-clean jet fuel made from non-recyclable plastics

Sustainable and green-energy company, Clean Planet Energy, have announced a new product in their mission to significantly reduce carbon emissions in fossil-fuel led transport. Branded as ‘Clean Planet Air’ in their launch video, the certified Kerosene / Jet Fuel can be used as a direct replacement for the fossil-fuel equivalent, yet it reduces C02 emissions by a minimum of 75% in comparison, whilst removing thousands of tonnes of waste-plastics from the environment every year. Clean Planet Energy’s mission is to remove over 1 million tonnes of waste-plastics from the environment every year, and they achieve this by launching ecoPlants which convert this plastic into new products, including ultra-clean fuels and petrochemical feedstocks to make new circular-plastics.

The plastics used by Clean Planet in their ecoPlants would otherwise be going to landfill, incineration, or worse, entering the oceans.

AuREUS System Technology, invented by Carvey Ehren Maigue from Mapua University in Manila, the Philippines, is a material that can be attached to a pre-existing structure or surface to harvest UV light and convert this into visible light to generate electricity. Using ultraviolet rays, on a cloudy or a sunny day, Carvey’s material will still generate electricity. The particles in his material absorb UV light causing them to glow. As the particles “rest” they remove excess energy. This excess energy bleeds out of the material as visible light, which can then be transformed into electricity. Current prototypes successfully achieve this on windows and external building structures. Not only has Carvey invented an efficient process to generate renewable energy, but he uses upcycled crop waste to create a closed-loop design process, so nothing is wasted. AuREUS System Technology conserves space using pre-existing structures, utilizes current resources and waste streams, and supports local agricultural communities. This element of his invention is particularly clever and shows the close link between farming and technology.

Racing to Innovate How the next-generation is pushing the boundaries of solar

by James Loginov

SINCE THEIR FOUNDING IN 1989,

the University of Michigan Solar Car Team (UM Solar Car) has built 15 solar race cars. Currently, their working on production of their latest model for the American Solar Challenge. In addition to winning this event nine times, the team has also secured 7 Bridgestone World Solar Challenge podium finishes, and won the 2015 Abu Dhabi Solar Challenge. UM Solar Car has become America's undisputed #1 solar car team. Over the years, it’s grown to encompass four engineering divisions - mechanical, electrical, aerodynamics, and strategy, as well as operations and business - yet remains an entirely student-run project.

“Joining the team means joining a tightknit community, including hundreds of team alumni as part of a global solar racing community. It's a chance to engage with complex subjects, from energy storage to international shipping and weather modelling, all in a hands-on, open-ended capacity that goes beyond any classroom experience.

If I had to choose one characteristic universal among Solar Car members, it would be the pursuit of excellence - to approach a problem, figure out a solution, and to keep finding better, and better solutions. That's the operating philosophy of our team, it's how we've maintained our competitive edge over 30 years, and it's why our team members opt to spend 40, 50, 60 hours on top of their academic and personal commitments working on the Solar Car every week.”

- Steven Zhang, 2021 Project Manager UM Solar Car brings together students from various backgrounds and disciplines to work together towards a common goal: build the best solar vehicle possible to win the Bridgestone World Solar Challenge (BWSC).

A race like no other, the BWSC is a biennial, 3,000 km trek through the Australian Outback - from Darwin to Adelaide - with every vehicle powered exclusively by energy from the sun.

Like the Daytona 500 or 24-Hours of Le Mans, the BWSC is not just about speed; everything about the car and the team is stress-tested to the extreme.

This is a true endurance challenge. With very fine margins between winning and losing, even finishing is a huge achievement.

MARCH• APRIL2021 /// www.nacleanenergy.com

“The Bridgestone World Solar Challenge is such a tough race because you can show up with the best technology, the lightest car, and still not reach the podium. To be able to say that you raced 3000 kilometres, and conquered the Australian Outback, is a huge achievement after all the countless hours of work; and something to be proud of.”

- Zack Piper, 2021 Operations Director

In 2019, Halmstad University Solar Team's battery caught fire during testing. Durham University Electric Motorsport stepped in to save them by donating an almost identical battery, and worked through the night to help repair the Swedish team's vehicle. Other teams were not so fortunate…

Solar Team Twente was knocked out of the race by strong winds, while the Vattenfall Solar Team (winners in 2017) were eliminated when their car caught fire just 263 km from the finish line. UM Solar Car survived the full distance to secure a spot on the podium with a 3rd place finish.

“To win the Bridgestone World Solar Challenge, you need more than a good design. You need a team filled with enthusiastic members that are passionate about getting the car to the finish line as quickly as possible.

It's an amazing competition, but the race is gruelling.

It demands dedication, attention to every detail, practice, and an adaptable race strategy that gets us all the way to Adelaide and the finish line.”

- Connor Boerman, 2021 Engineering Director Not so much 'Fast & Furious' as 'Smart & Serious', BWSC challenges young engineers and extraordinary minds from UM Solar Car - and other (mainly university-based) teams from over 30 countries - to push the limits of innovation and engineering.

Together, these young innovators contribute to the ongoing evolution of both solar power and solar-powered vehicles.

On July 19, 2019, the UM Solar Car team unveiled their new car: 'Electrum'. Building on their previous vehicle's success, the team overhauled the electrical system, ditching the traditional lithium-ion battery in favour of a new Li-Polymer battery pack. Improved aerodynamics created more space for solar panels behind the cockpit. With the addition of trapezoid-shaped solar cells (instead of rectangular) they also managed to include a higher density of cells in the same amount of space.

James Loginov is Head of Marketing & Communications at EKO Instruments.

EKO Instruments is sponsoring the University of Michigan Solar Car Team, and five other teams from around the world at the next 'Bridgestone World Solar Challenge', as part of the 'EKO | emPower' programme; providing the latest environmental instruments, technical partnerships, and support to young scientists, designers, students, and engineers around the world.

Helping them to innovate, achieve their goals, advance their ideas, and build a better, more sustainable, future.

Powered entirely by the sun, efficient energy generation and management are crucial at every stage of development. Even during the race itself, the team needs to know precisely how much energy they should be generating, how much energy they are generating, and how much they are using.

Heading into 2021 the pressure is already on to make the next racewinning breakthrough.

OTHERWORLDLY TRACKER: ENGINEERED FOR GREATNESS

“Solar Car racing is one of the most important events within the renewable automotive industry. Not only does it allow a community of like-minded innovators to come together, but it also pushes the development of the newest and greatest innovations within the automotive landscape.

There are not many programs that can continuously bring people together on this magnitude to change the world towards a better and cleaner future.”

- Jared McLean, 2021 Business Director With Solar PV alone predicted to account for 60 percent of all renewable capacity additions through 20251, and the solar vehicle market estimated to be worth $4.08 Billion by 20302, the young engineers of the UM Solar Car team are already on the cutting edge, racing to innovate and unlock the full potential of solar power.

The Bridgestone World Solar Challenge announced on the 12th of February that this year's event had been cancelled, due to ongoing uncertainty caused by the pandemic. The next race will occur in two years. EKO Instruments will continue to support the Michigan University Solar Car Team through the emPower programme as they adapt to new challenges and prepare for 2023.

Data is the Problem… and the Solution Performance challenges stunting solar’s success

by Katie Applebaum

SOLAR PV PLANTS PLAY A KEY ROLE

in the modern energy generation mix – however, they frequently do not perform to their full potential. This is largely due to two key factors. First, as PV plants have few moving parts, the need for maintenance is not readily apparent and can, therefore, be easily underestimated.

Second, and arguably most importantly, PV performance data can be particularly challenging to assemble and analyze. As a result, faults and underperformance often go undetected, resulting in reduced generation and, subsequently, reduced returns.

To avoid these pitfalls, owners and operators must prioritize effective asset management and data analysis. In doing so, they will optimize performance and maximize returns.

Addressing the solar data challenges There are a number of challenges to overcome in securing valuable operational insights from solar PV project data.

Stark variations in solar resource, plant topology, component mix, and variety and quality of project data can all complicate project-scale analysis, making it difficult for owners to quickly access insights.

Best practice for monitoring and managing solar asset health

Replacing obviously damaged equipment is what most people think of when it comes to maintaining and improving asset health, but equally important is maintaining the electrical health of the asset – inclusive of voltage, signals, and temperatures.

There are also physical influences on-site that can hinder the performance of solar panels. For example, the growth of vegetation nearby, damp heat, and destructive precipitation can reduce performance over time without the owner realizing their assets are actively being damaged.

These factors are impossible to see visually, which means that issues caused by poor electrical and mechanical health or slow-burn physical influences are often mistaken for simple fluctuations in resource. For example, in order to recognize when low performance is owing to a fault around voltage, data from related sensors must be closely monitored. As such, adopting a datadriven approach to identifying poor performance within a PV plant, and rectifying the underlying issues, is arguably the most important way to improve project returns.

10

Effective asset optimization requires separating out causes of underperformance from the “noise” of everyday operational data, and setting this data in its environmental context. Finding and addressing apparently minor faults and anomalies that would otherwise go under the radar – such as those physical, electrical, and mechanical factors outlined above – are essential to ensuring the asset continues to perform well for the long term.

To understand the true causes of underperformance across a solar array, it is crucial to integrate: • Current and historical meteorological data, • Surrounding forestry and vegetation, • Operational and grid activities, • SCADA data from the individual asset, and • Benchmark this data against the surrounding panels.

These multiple data streams, when set in context of the project, will allow an asset owner to immediately pinpoint whether underperformance can be attributed to low irradiation or a technical error that can be addressed.

Variation in solar PV data

However, there is a fundamental challenge to quickly and easily separating out causes of underperformance and comparing them at the project, portfolio, and industry-wide scale.

The format of data gathered across solar farms is extremely varied. While wind has only a handful of major OEMs around the world, the lower financial barrier to entry in the solar tech market means that there are hundreds of solar OEMs – all of whom track and report on the data from their components in a different way.

MARCH• APRIL2021 /// www.nacleanenergy.com

This creates a sizable data challenge if an owner wants to compare and benchmark the performance of their assets comprehensively. Unfortunately, many solar asset owners simply do not have the means (both in terms of human resource and cost) to dig through these very different data streams in order to properly compare performance. However, with support from an AI driven platform and industry expertise, it is possible to cut the time necessary to translate and analyze data down from weeks, to mere hours.

To improve access to this data and domain expertise, and support asset owners across the industry in benefiting from the insights into PV performance at portfolio level, solar asset owners and manufacturers must translate these many competing data streams into a common dataset.

They need a dataset that allows for the comparison of solar asset performance - regardless of OEM or environmental context. With this insight, asset owners can recognize whether an asset is underperforming compared to its immediate peers, wider portfolio, and (as more data is accumulated) the industry as a whole.

From these data insights, owners and investors with solar portfolios can validate upgrades, changes to insurance premiums, and day-to-day operations.

The ubiquity of solar power has contributed to faulty assumptions around the simplicity of this method of generating power. Investors and asset owners, whether new to the solar industry or seasoned professionals, would be smart to research and better understand the production benefits of data-driven solar operations.

Lightning vs. Solar

Risk detection, protection, and mitigation of utility-scale solar lightning surge events

by Daniel J. Sylawa

Utility-scale solar project site locations are chosen for many factors, including solar resources, available land area, topography, electric grid capacity, and financial incentives. Weather usually does not play a significant role in this selection process. However, extreme weather events, such as lightning, can negatively impact both plant operations and economics. From an asset management perspective, it is important to understand both the risk factors associated with lightning-related surge events, and the available protection strategies that can help minimize their impacts on array performance.

Figure 1: Lightning can impact the operability of utility-scale solar PV installations, so it is important to understand the risk factors related to lightning, as well as the surge protection strategies that can minimize lightning’s impact.

Resources are available to aid in these efforts.

Standards such as NFPA 7801, analysis of PV field reliability2, and other sources3 can assist in identifying the major PV solar risk areas associated with lightning-related surge events. NFPA 780 also provides guidance as to selection and installation of surge protection devices (SPDs) for solar arrays. In the following sections, we will examine how these resources can help improve the reliability of utilityscale PV solar arrays.

Risk Detection

Highly dependent on location, some level of lightning-related risk almost always exists for utility-scale PV solar installations. Due to their typically ground-mounted location, the incidences of direct lightning strikes are, thankfully, rare. Lightning-related secondary surge events, however, are encountered with more frequency. Some of the major factors associated with lightning risk include: • Location risk: Geographic location is a major factor in determining lightning risk. The lightning risk assessment contained in Appendix L of NFPA 780 is a good starting point to determine associated risks for solar installations. A few general trends can be observed. From the isokeraunic flash density map, it can be readily seen that, as PV solar installations have moved out of their early adoption locations in California, they have been installed in areas of increased lightning risk. From a risk management perspective, this has heightened the need to provide appropriate levels of surge protection against lightning-related surge events. A related risk factor is area of array ground coverage; with ever larger utility-scale arrays being installed in areas with higher flash density, the risk associated with lightning-related surge events has also increased.

• Equipment risk: Outside of direct lightning strike damage, the primary risk to utility-scale PV solar installations is damage to electronics and PV modules from secondary surge overvoltages. These overvoltages damage equipment by exceeding the dielectric strength of internal components. Unlike direct lightning damage, these surge impacts can be cumulative, reducing the ability to determine a direct causal effect between failures and events. Lightning events that cause overvoltages do not always strike within the boundaries of a solar array. Those that occur on utility pole lines, light standards, and other structures outside of the area of the actual array boundaries, increase the overvoltage risk to array equipment associated with these events.

• Operational risk: For PV solar arrays, operational risks are a function of several factors, which include type of equipment failures, frequency of occurrence, lost power production, and repair costs. PV field reliability analysis, which assesses the field dependability of PV solar installations, can help determine operation risks. From a lightning-related surge event perspective, these studies indicate that while direct lightning strikes are rare, area lightning events are more common. As such, the related failures associated with these events may not be reported directly under lightning strike information, but may instead be contained under array component failures.

While lightning-related surge events can seem to be a somewhat random occurrence, understanding their risks can help determine the levels of surge protection and mitigation steps necessary to reduce their impact on PV solar array performance.

Protection

Available state of the art of surge protection technology is well developed. In lightning surge event applications, the objective is to protect all electrical components involved with power production, data, and monitoring within utility-scale solar arrays. This includes the AC and DC side of inverters, SCADA systems, weather stations, solar trackers, monitoring instruments, as well as ancillary electrical systems. For PV solar applications, detailed surge protection device and installation recommendations can be found in Chapter 12 of NFPA 780. As always, the grounding and bonding requirements of NEC 250 and solar installation requirements of NEC 690 must be followed to ensure safe and effective surge protection.

Two of the most critical factors for choosing direct-array connected SPDs are discharge circuit currents rating (In) and voltage protection rating (VPR). This can be thought of as the nominal maximum surge current (In) which the SPD will suppress surge voltages to below the overvoltage tolerance of the protected equipment. As an example, for the DC array side of a solar inverter, NFPA 780 recommends the use of an SPD with a discharge circuit current rating (In) of 20kA 8/20 µS per mode. The SPD VPR typically is recommended to be no greater than three times the maximum PV system voltage. For 1500V utility-scale PV solar installations, this will be 4500 V. Use of SPDs that meet these ratings will reduce failures and extend equipment life.

Mitigation

For utility-scale PV solar installations, array layout and design play an important role in lightning surge event mitigation.

NFPA 780 again offers insight in this area. As an example, the recommended installation point for DC SPDs is at the combiner or recombiner box; this is considered the output of the array. If the distance from the combiner box to the inverter is greater than 100 feet (30 m), a second DC SPD should be installed at the inverter. This is a common option from most inverter manufacturers. If the inverter has multiple MPPT inputs, SPDs should be installed on each input. For installations that use string inverters with internal combiner boxes or external cable harnesses, installation of the DC SPD at the inverter will usually be adequate.

However, for extremely long cable runs (in excess of 100 feet (30 m) from the array to the inverter) a DC SPD closer to the actual array output point should be installed.

As the utility-scale solar industry moves to higher power PV modules, including bifacial types, the DC SPD application guidelines do not change. This implies that with increased array power output, on a cost/watt basis, surge protection costs fall. This will help lower both the construction and operational costs of utility-scale solar arrays.

Unpacking Community Solar

by Robert Benedict

FOR ANY SOLAR NEOPHYTES, AS WELL AS OUTSIDE

industry experts who may not have a handle on the specifics, community solar projects can be described as ownership and subscription programs. This business model allows participants to own or be a third party to the program, enabling them to share the energy generated. Rather than build on their own property (impractical for most apartment dwellers), community solar customers benefit from the power produced by their share of the system. The Subscription model allows participants to become subscribers, so they pay a lower price for the electricity sourced from the community solar farm. They don't own the panels, but they can buy their power at a reduced rate.

When projects are ownership-based, you can either purchase their panels up-front or finance them through a loan (provided by the project developer or your bank). In this way, ownership-based community solar models are very similar to purchasing a rooftop system. The main difference is that no system will be installed on your roof or property.

Instead, you own a set number of panels in the array, or a certain number of watts out of the solar project's total capacity.

In ownership programs, you can only purchase enough shares to meet your annual electricity usage. A matching proportion of the project's actual output is credited to you through your electricity bill or some other arrangement with the project administrator.

Ownership-based projects can be complicated to develop and administer. The ownership factor can be a barrier to entry for those who do not have the capital or credit rating necessary to get involved. Complications arise when the project is initiated by the community hoping to benefit. Another hurdle occurs when distributing the solar investment tax credit (ITC) incentive if the project developer does not have a substantial tax liability.

In subscription-based community solar programs, participation is more fluid; A third party or a utility company will invest in, develop, and own the solar community project, allowing them to take advantage of associated tax credits and extend an opportunity to the public to participate.

Program details will vary, but most require no upfront fees to join while offering savings right away. In this case, subscribing to a community solar project is akin to signing up for a green power program, except that instead of paying a premium for clean electricity, participants typically pay a lower price for their electricity.

As with ownership-based projects, there are limitations on participation with many subscription programs. Depending on your state and utility company, you may need to reside within a certain distance from the community solar project; your utility's coverage area can affect your eligibility to join the program.

Many community solar companies also limit how much electricity you can receive from the project (investing in 120 percent of average electricity consumption being the rule-ofthumb upper limit).

Most subscription-based programs make it easy for you to sign up, and to cancel. For example, should you decide to opt-out or move to a different utility area, your energy share will become available to the next interested participant in line for the program.

Given all of these benefits, it's no surprise why community solar is becoming an increasingly popular offering from new energy companies, utilities, and more. With so many choices, it’s important for anyone considering a community solar program to comparison-shop across all available offers (including rooftop options) to find the one that offers the best value for them.

Thanks to Virtual Net Metering (VNM) and similar policies in a growing number of states, the community solar power option is gaining steam as the primary means for a growing number of people to participate in the benefits offered by solar power. Like net metering for rooftop solar systems, VNM and similar policies allow households and businesses to receive net metering credits associated with a renewable energy project installed at a remote location. These credits can be worth as much (or close to) what they would pay for electricity from their utility; every unit (kilowatt-hour or kWh). Electricity generated by the community solar farm will effectively reduce the participant's power bill, either as a one-forone kilowatt-hour basis or equalling a monetary credit.

Because community solar allows people to go solar even if they do not own property or roof, it’s an attractive option for renters or those who live in shared buildings. Effectively, it lets them take advantage of a solar power plant whose electricity is shared by more than one property.

This is, of course, its the biggest benefit; community solar gives members of a community the option to buy electricity for less than they would ordinarily pay to their utility.

The Importance of Revenue Grade Energy Meters in the Solar Industry

by Nikki Henningsen

Revenue grade energy meters play a crucial role in the solar energy industry. Whether for calculating inverter efficiency, measuring net energy production, or monitoring an on-site energy storage system, revenue grade energy meters are vital to maximizing the value of solar energy generation. To understand their role within the solar system, think of a cardiac monitor used to measure a patient’s heart rate and rhythm; a revenue grade energy meter performs a similar task by precisely monitoring energy flowing through the solar system, detecting irregularities, and providing crucial insights into the overall health of the installation.

Available from a range of manufacturers, revenue grade energy meters were first developed as a way for building managers to the track energy consumption of individual systems within a facility. Imagine a manufacturing plant and its various energy loads. Specialized production tools, HVAC, lighting, office equipment, and other essentials all consume energy throughout the day. A monthly power bill cannot provide meaningful insight into energy waste, but a revenue grade energy meter can collect detailed energy consumption data for specific systems or equipment.

High-precision, revenue grade measurements are critically important, particularly in net metering applications, which require meters that comply with strict accuracy requirements. In fact, the term “revenue grade” specifically refers only to those energy meters that meet the accuracy benchmarks defined by the American National Standards Institute (ANSI), which outlines three accuracy classes in their C12.20-2015 standard: 0.1, 0.2, and 0.5. To be considered revenue grade, meter accuracy must be third party tested to conform to 0.5 percent or higher.

Solar systems may vary in size and energy output. Regardless of scale, they contain the same critical components for energy storage, including inverters, circuit breakers, and batteries. Each component requires careful and constant monitoring, making highprecision energy data from a revenue grade energy meter invaluable.

Here are a few ways the solar industry uses revenue grade energy meters.

MORE THAN 100,000 PROJECTS IMPLEMENTED IN

Calculating Solar Inverter Efficiency

Solar inverters are integral to solar energy systems. These sophisticated devices are responsible for converting the direct current (DC) output from the solar array into the alternating current (AC) that is used throughout a facility. A small amount of energy may be lost during this conversion process. This amount can be identified by installing revenue grade energy submeters on both sides of the inverter to calculate efficiency. Not only does this data help identify upgrade opportunities, but the metered energy data can help highlight hardware issues that may go undetected without constant monitoring.

Measuring Net Energy Production

Net metering is an incentive program adopted by 34 states and several territories within the United States,1 and another important way that revenue grade energy meters are utilized within the solar industry. Net metering allows customers to send their surplus electricity back to the electrical grid in exchange for credit, which is applied to offset energy costs incurred during the month.

A revenue grade energy meter is required to monitor the flow of energy and confirm the exact amount of energy generated, which is then submitted to the utility for credit. Largescale solar applications typically need multiple meters installed, while small installations may only require a single, bi-directional meter to monitor both energy consumption and generation. The precise solar production data directly benefits customers by helping MORE THAN 64 COUNTRIES to lower monthly energy bills.

Commercial and industrial customers rely on several strategies to limit their energy consumption during peak hours.

In addition to facility upgrades, one technique that continues to gain traction is installation of an on-site energy storage system (ESS), which allows energy from the grid, or solar, to charge large batteries during off-peak times. Later, the stored energy supplements grid power during peak hours to lower demand, a strategy known as “peak shaving”.

Energy storage allows for the efficient distribution of energy resources. It can also increase grid resiliency by guaranteeing that power is always available, even during times of high demand or power outages. In addition, when the source of the stored energy is on-site solar, the ESS effectively compensates for periods of low solar production, smoothing out the available energy from a solar system throughout the day and reducing reliance on grid power.

Facilities that utilize on-site energy storage need more than just a large battery to effectively cap their demand.

A sophisticated control system, powered by machine learning, interprets where and when energy is being used, and automatically compensates for peak consumption by engaging battery power at the right moment. Revenue grade power meters supply the control system with a constant stream of precise energy measurements. The granular data is used to make split-second decisions to mitigate power outages, reduce peak demand charges, and maximize the value of energy generation.

Increasing Need for Revenue Grade Energy Meters The United States solar industry employs approximately 250,000 people, and is comprised of over 2.6 million solar energy systems2. As solar panels, inverters, and on-site energy storage systems continue to improve in efficiency and price, solar energy will be adopted at an accelerated pace. Whether it is a relatively small solar system or a sophisticated, commercial implementation, the need for revenue grade energy meters to provide accurate, timely energy measurements remains essential to evaluating system performance, maintaining peak efficiency, and obtaining maximum savings from incentive programs.

Big and Bigger

The opportunities and challenges of large-format solar modules

by Aaron Hall, Daryl Hart, and Joe Thorpe

THE PAST FEW YEARS HAVE SEEN AN AMAZING

amount of solar module innovation. One of the biggest trends is literally about bigness—the emergence of the large-format, high-power module. With peak power ratings already well over 500 watts (and pushing toward 600 watts and beyond), these mega-modules are made possible by another photovoltaic technology trend: the transition beyond 72-cell modules featuring 156-/166-mm cells, to larger modules using cleverly manipulated 182- and 210-mm slices of silicon.

Manufacturers have implemented cell-splitting, shingling and tiling, multi-busbar architectures, and dense cell-to-cell interconnect schemes (as well as bifacial technology) to drive up the power output in these supersized modules. Although the larger modules are just starting to be shipped at volume, market research firms predict they will dominate the utility-scale solar market within a few years.

Large-format modules present both opportunities and challenges for developers, engineering, procurement and construction (EPC) companies, and operations and maintenance (O&M) providers. This article will examine some of the issues around the new big modules from the perspective of all three business sectors.

Anything New Means There’s a Learning Curve

The new, larger form factor and higher wattage of these modules will mean that everyone - designers, developers, owners, and financiers - will need to ensure all the implications have been considered. One key issue is compatibility; for example, optimizers may have voltage limitations. It will also be crucial to determine whether the larger modules are pushing amps in a way that requires upsizing wires, combiner boxes, and other balance of systems components. In addition, there’s the question of possible warranty implications; specifically, whether using large-format modules will have any impact on the warranties of other components in the project, such as mounting systems that may not have been wind-load tested or certified for the larger modules.

costs - to the tune of several cents per watt. Simply put, it means fewer modules to ship (and, in the case of 182-mm modules, more watts per shipping container), fewer modules to mount on fewer trackers or fixed-tilt racks (and more watts per tracker row), and fewer strings to connect to achieve the same installed capacity of the power plant. Plus, fewer systems to operate and maintain once the plant is up and running. The result? Decreased capital expenditures, lower levelized cost of electricity, and higher net present value, all of which has developers and asset owners excited.

From a developer-owner’s perspective, there is additional risk any time a new technology is introduced, whether it’s in terms of financial bankability, higher insurance premiums, or simply the durability and performance of the module. While Tier 1 manufacturers have (mostly) good track records when it comes to quality and reliability, it’s early days in terms of real-world power generation numbers from the mega-modules, let alone degradation, failure rates, or other field performance data. Given the larger surface area of the modules, there could be concerns with cell microcracking or susceptibility to extreme weather events such as damaging winds, hail, or snow loads.

Site Design Advantages and Tradeoffs

More Power Means Lower Costs

The main advantage of these large-format modules is straightforward: the higher power output per module allows a reduction in the required balance of system (BOS) and electrical BOS components and, most importantly, lower installation

18

MARCH• APRIL2021 /// www.nacleanenergy.com

Large-format modules offer a tantalizing opportunity for developers, giving their landowner partners and EPCs more flexibly to utilize and benefit from the project site acreage. A space-constrained site could include additional megawatts of capacity; for many markets and scenarios, this is a worthwhile tradeoff with a corresponding specific yield reduction. This flexibility could also provide transmission system injection benefits when using a solar-plus-energy storage system equipped with large-format modules.

Site designers will need to factor in the increased module size in how they lay out the tracker rows, increasing the spacing between the mounting structures to keep the same ground-cover ratio (GCR),

Aaron Hall is president, Daryl Hart is vice president of utility-scale project development, and Joe Thorpe is senior vice president of O&M operations at Borrego, a nationwide developer, EPC and O&M provider for large-scale renewable energy projects throughout the United States.

Borrego /// www.borregoenergy.com

if that is their goal. Large-format modules do allow for a boost to the system’s DC kilowatts by increasing the GCR, while maintaining reasonable construction and O&M access (typically about 10 feet between rows).

One cannot assume that large-format modules can just be swapped in on trackers, since the tracker rows might become too long for the available north-south dimensions of the site. The varied voltage and amperage schemes of different mega-modules will require close attention to the electrical elements of the system design—a midstream change in module procurement choice could trigger a DC wiring redesign. Larger tracker structures may also translate into the need for bigger, deeper (and costlier) foundations and more robust, smarter systems that can handle the added dynamic wind-load potential. Be prepared to account for permitting issues if the height of the modules on a fully rotated tracker exceeds a typical 15-foot maximum height zoning requirement.

Less Complex O&M

From an O&M perspective, megamodules will mean less plant complexity, fewer parts to inspect, maintain and manage, and more efficient plant operations. Since labor makes up the biggest chunk of O&M costs, savings could be significant over the lifetime of the plant.

Given the large variety of module sizes and electrical characteristics coming to the market and the lack of standardization so far, the larger modules do present some O&M challenges. For example, how easy will it be to get proper replacement modules—under warranty or otherwise—in the future? The issue of inadequate supplies of spare modules already dogs many existing solar plants, and could become even more acute when the mega-module era ramps up in earnest. Taller tracker arrays may also require some additions to the onsite O&M toolkit—and hard costs in the contract—as boom-lifts will be needed to service the big modules.

Large-format modules offer a pathway to significant savings on the development, construction, and operations of utility solar power plants.

It’s a safe bet that their rapid adoption into new project designs will help accelerate the clean energy transition.

How to Successfully Secure Financing for the Coming Community Solar Boom

by Jamie Hutson

One of seven sites in a 25MW community solar portfolio installed by DSD in Schenectady County, NY.

Community solar promises substantial good for the environment, for business, and for communities. Yet it was still very much untapped until the last few years, with only a handful of projects scattered across a handful of states that were aggressively developing policies and programs around it.

That’s all changing. Just prior to COVID-19, energy experts were chirping how community solar was finally showing signs of serious growth. We see every reason for those expectations to bear fruit in 2021. Why? Because community solar seems insulated from recession impacts, thanks to its lower commitment and higher flexibility.

Due to a number of moving parts (and large degrees of variability from state to state) successfully securing and structuring financing for community solar projects can be more complex than other projects. Here are three ways to make the financing process for community solar projects – and other projects - run smoothly.

1. Establish in-house expertise on state programs

As of last summer, 20 states had developed policies or programs in support of community solar projects, which exist in 40 states. Minnesota, Massachusetts, and New York all got programs rolling early on and continue to lead the way, representing nearly three-quarters of the 2,625 megawatts of community solar currently developed. The success of your project may depend on navigating the degrees of variability. Many of these programs set guidelines and incentives for developers and subscribers, helping the industry gain efficiency and create more customer-oriented resources. Some, like Maine, Massachusetts, and New York, include locational value based on how a community solar site can meet the geographic needs.

Most community solar systems are between 2-5MW, and serve a number of different customers. These systems are often built in out-of-the-way locations, taking advantage of local unutilized or underutilized land, such as old landfills. In addition to an interconnection agreement with a utility, remote net metering is typically extended through a subscription A 10MW cummunity solar to multiple offtakers. In some states, that system in Lenox, NY includes large commercial and industrial or municipal customers. However, a portion -- usually 50 percent or more -- must be residential or non-demand offtakers.

Finding the right offtakers adds a layer of challenge to the commercial and industrial market from a project finance perspective, but there are ways to approach community solar that raise your chances of success.

2. Standardize documents to help clarify varying program details

With so many states implementing so many different programs for varying projects, taking a standardized contracting, documentation, and due diligence approach to community solar will demonstrate efficiency with lenders and financial counterparties.

Aggregator agreements set the guidelines for community solar aggregators that recruit and enroll subscribers to a project. This can differ from state to state; some aggregators might only work in New York or Maryland, for example. Standardized terms and conditions help both subscriber managers and developers succeed by specifying subscriber FICO scores or credit ratings, subscription thresholds the aggregator must

20

MARCH• APRIL2021 /// www.nacleanenergy.com

maintain, and termination rights of both the subscribers and aggregators.

This is a heavy but necessary lift that allows for better communication with lenders.

A knowledgeable developer can quickly and easily summarize how each of the standardized terms and conditions at the project and aggregator level all tie together to conform with the requirements and rules of that state program. Developers with stateby-state expertise increase efficiency both for themselves (as they manage all those different processes) and for lenders conducting due diligence.

3. Standardize due diligence covering the full scope of the project

Performing holistic due diligence across a community solar project goes a long way in establishing uniform project details, which makes it easier for a lender or tax equity investor to quickly understand what’s being done and where they need to focus their efforts. In particular, areas like interconnection, revenue streams, site control, and permitting can make or break a deal.

A 3MW solar rooftop canopy For example, obtaining offtaker FICO andground mount installed by DSD at scores are a must when conducting Southern Connecticut State University offtaker due diligence. A delinquent subscriber could mean months of backand-forth in legal detangling, and finding a new subscriber. Too much churn could result in problems for your project.

Performing the proper due diligence will help lenders and other financial counterparts move more efficiently. And, in the end, when it comes to project financing and capital markets on a distributed portfolio, efficiency is the critical piece to unlock the best financing terms.

There are many pieces that need to come together for community solar to create wins for all involved, making it (in theory) one of the most complicated types of project for which to secure and structure financing. But the processes mentioned above aren’t exclusive to community solar financing - they can also be applied across the board to any other project a developer is financing. By having a deep understanding of state level programs, standardizing documentation, and performing the proper due diligence, financing community solar projects - as well as any other solar projects - will run much more smoothly and efficiently.

Solar Lights Up Sports

by Philip Ferguson

YOU’VE PROBABLY SEEN OUTDOOR SOLAR

lighting around your neighborhood, lining front walks like miniature runways, providing a decorative touch to nighttime landscapes. But what about on a larger scale? Surely those lowpowered displays couldn’t light an entire stadium?

Actually, they can. Solar lights have come a long way from their residential predecessors. Thanks to the latest technology, the solar energy conversion efficiency has advanced to where they can produce the energy needed for regular use in the more famous sports fields or stadiums. As with any clean energy technology, however, powerful solar lighting comes with a few pros and cons.

next trend for major stadiums - the current pandemic has shown that businesses need more backup solutions.

Go wireless

Forget clumsy installations and long-hours of scheduled maintenance to fix the wiring system. At last, you can benefit from a ready lighting solution. The solar flood light all-in-one design requires no wires going around the pitch, which is safer for bystanders and players as well. They are really easy to install.

While periodic maintenance might still be a factor, the standard solar light is versatile. Basically, you can mount these sports lights anywhere you want. As long as the luminaries' weight is not a problem.

Better safety

Save Money

For starters, and perhaps the most obvious, solar lights save on the energy bill. Solar-powered LED sports lights gather the sun's energy and store it in batteries. You turn them on and off with the touch of a light tap on your smartphone screen. They can also be set to automatically switch on when it gets dark. This unique feature allows them to be completely independent of the power grid, while still allowing for the sale of solar energy surpluses.

This can be especially helpful if, as a stadium owner, you need to support other investments. Exporting energy might well be the

Thanks to the 12V low voltage, solar fixtures reduce the chance of getting an electric shock. The compact design allows no load loss because the solar system planning also improved over the years.

Generally speaking, LED sports lights are lighter than traditional light sources. So, you get the best from both worlds.

You will not have to compromise any safety precautions due to the solar panels. In fact, you can count on several accessories. As well as custom installations for indoor playing areas.

LIMITATIONS Dependent on environment

Batteries need daylight to recharge fully. Then again, they cannot charge quickly on cloudy days.

The performance of the photovoltaic panel is calculated under the STC conditions (Standard Test Condition). In

detail, this means an integrated solar irradiance of 1,000W/m2, at the temperature of 77°F (25°C), and with a spectral distribution of 1.5.

All manufacturers test their products in order to define the power of their solar light panels. But they still need up to 10 hours to recharge. So, if it keeps raining on the sports field for days on end, drained solar sports lights might not be able to light up.

Can't charge at night

If you plan to host most of your sports events during the night, you might want to reconsider the idea of using solar lights only.

In this case, it is better to opt for a hybrid lighting system, which includes traditional, wired sports lights. Or, you should request a grid-connected installation.

In the latter case, during the first hours, your lights would consume the solargenerated electricity. Then, when the battery charge is not sufficient, the electricity grid will guarantee the power supply.

Need regular cleaning

The main focus of periodic maintenance is to clean the solar panels. In detail, the dust accumulated on the cells will affect the solar energy conversion efficiency.

Luckily, the cleaning procedure is simple and involves no dangerous chemicals. Most manufacturers will remind you to only use warm water and, perhaps, a specific cloth to clean them.

Usually, maintenance cleaning takes minutes. So, whether you use solar sports lights for a football stadium or a volleyball court, you should not have any issue with scheduling regular cleaning.

Heavy metals in solar panel On a more serious note, a solar panel contains heavy metals such as: • Cadmium • Lead • Zinc Improper disposal will be harmful to the environment. If they are badly managed at the time of replacement, these panels could create pollution and health problems. So, you must consider a recycling plan.

Conclusion

Most likely, solar lights in the sports field will change the way we experience our beloved matches. Without a doubt, this new trend will rise in the following years to come. Mainly because the post-covid economy will have to deal with renewable energies and better living conditions.

The latest generation models will transform the ordinary stadium into a more eco-compatible arena. At the same time, the solar panels will provide a new source of income and lighter energy bills.

Today, the cost of recycling is higher than sending them to a landfill. A temporary solution is to store them until better times.

But we must be diligent and store these harmful materials very carefully.

Feasible applications of solar lighting in the sports field 1. Mobile light tower

Before considering some of the uses of mobile light towers, it is better to remind ourselves of their main function. That is, provide brightness in any place where standard installations might be a problem.

A movable light tower provides excellent emergency lighting. For example, at the soccer field sidelines for first responders. Dirty tackles can easily lead to injuries. So, a well-lit area for first-aid is useful.

Similarly, golf players who like to train after work can enjoy a mobile light tower in their driving range. The owner could benefit from providing a service and not spending money on just that client's late training obsession.

2. Solar panel on high mast light pole

High mast floodlighting is ideal for installing solar sports lights. By placing the solar panels so high, you reduce the risk of any accidental obstruction for the solar cells.

These lights are highly reliable. So, you can install them in parking lots near the sports field and between the stands.

Thanks to remote lighting control, they are easy to monitor without having to climb the high mast. Plus, you can set different light intensity levels. This means that the players and spectators will never suffer from the lights being too bright.

3. Stadium roof attachment

One of the best ways of taking advantage of their autonomous, off-grid system is to mount them where other floodlights cannot stand.

You can install the solar panel at the top of your stadium roof to receive sunlight. Then, a custom installation will connect the solar module to the roof-mounted sports light.

Imagine the most creative domed stadium lighting layout. With independent solar sports lights, you can achieve your dream design. Light up the athletes from above. Create a cozy atmosphere for your special guests. Even the umpires and other officials will appreciate that!

The Challenge of Electrifying the Modern Home

by Daniel Goldman

We live in a world vastly different from even a few years ago. Homeowners and commercial business operators are increasingly concerned about climate change, grid reliability problems, 1,000-year storms every year, record numbers of damaging hurricanes, wildfires, and rising electricity costs. Many ratepayers fall victim to sustained power outages from weather events, rolling blackouts, and even a lack of sufficient generating capacity when the grid is stressed. Adding to all of this, living in a post-COVID world (with increased work from home and perhaps more home schooling) will make us increasingly vulnerable to grid reliability, impacting the entire family’s productivity.

As a result, homeowners and businesses have already embraced distributed energy resource (DERs) systems - principally home solar or small solar fields - to create what are effectively mini-grids and/or micro-grids. In fact, research forecasts that U.S. distributed solar installations will almost double from today’s roughly two million by 2022, and residential, commercial, and industrial energy storage systems will grow by orders of magnitude.

But to make this transformation convenient, effective, and safe, ratepayers need the help and cooperation of their local distribution utility. Virtually all homes and facilities will remain connected to the grid via the transmission and distribution systems for the foreseeable future, certainly to maintain backup power. At the same time, they will need systems that accommodate partial or fully-sufficient solar installations, as well as integrated energy storage systems, smart appliances, home EV chargers, and other options not yet in existence but on the horizon. They and their utilities will also need increasing amounts of information, delivered instantly, to support energy efficiency, demand response, and lower energy costs.

Unfortunately, most existing home and commercial electric meters installed

MARCH• APRIL2021 /// www.nacleanenergy.com

Local utilities can add value and enable DERs for their ratepayers by offering comprehensive interconnection options. As technology like this continues to grow, it can become, in effect, a “clearing house” for a much more distributed energy landscape. The world of distributed energy resources and a cleaner energy economy is already here. Both utilities and homeowners can greatly benefit from this and other technologies enabling greater clean, zero-carbon energy adoption.

by utilities don’t lend themselves to installing solar energy, EV charging, fuel cells, or energy storage. Worse still, when the grid fails, most homes cannot even make use of their DER resources that run in parallel to the grid and don’t allow for islanding. Most meter manufacturers simply didn’t imagine the locallyelectrified world in which we already live, and utilities’ planning, purchasing, and operational worlds didn’t include massive numbers of ratepayer-located DER installations. As a result, homeowners are often left with unexpected installation costs - often thousands of dollars - to keep their homes safely connected to the grid. Utilities are left with a growing fleet of DERs dumping power into a grid that is not ready to handle it. Those utilities that don’t find ways to solve these challenges are sure to run into grid management issues and frustrated ratepayers.

Luckily, emerging technologies are working to solve these interconnection and data sharing challenges for homeowners. In some cases, the DER technology provider manages the interconnection and sells data to the utility. In other cases, the utilities can install innovative, low-cost technologies like meter collars to capture data and reduce the cost to the homeowner. If we are to truly empower the homeowner, and advance this energy revolution while ensuring seamless integration with the grid, we need to think of these generation assets as appliances, no different than your refrigerator or HVAC system. The best way we’ve seen this addressed is at the meter. An electricity meter collar adapter can unlock the massive potential of DERs by turning the meter socket into the utility's all-in-one plugin point for solar, storage, electric vehicles and more.

By utilizing what’s already on the side of everyone’s home (the meter socket), a meter collar takes away the need for expensive installations and upgrades just to stay safely connected to the grid and gives utilities a reliable and secure data link with DERs once they’re installed. It makes sense to use a system that is easily adopted and integrated into existing homes, other facilities, and applications.

“Plug and play” devices are easy to install, integrate with utilities’ communications systems, and work universally across solar, storage, EV’s and even applications that have yet to come to market.

Daniel Goldman serves on the board of ConnectDER, a meter collar adapter startup, and is the co-founder and managing director of Clean Energy Ventures, a venture capital firm investing in climate tech startups that can mitigate the effects of climate change while providing strong venture capital returns.

How Energy’s Past Becomes Its Future

Alberta’s experience shows how old-energy skills can drive new-energy success

by David Pichard

NEW LEADERSHIP MEANS BIG CHANGES FOR ENERGY

policy in the U.S.—and possibly the world. Biden’s $2-trillion campaign plans to bring the U.S. electric grid to 100 percent zero-carbon resources by 2035, reflecting a monumental shift in federal policies boosting renewables across the country. The momentum is clear: oil and coal economies will slowly diminish, and big investments in green infrastructure are on the way.

The U.S. can look to the north to see how Alberta has successfully transitioned thousands of oil and gas workers to power Canada’s solar and wind industries.

Reviewing Alberta’s fossil transition, historically traditional energy states like Pennsylvania and others can apply its strategies for success.

Refocusing Skills through Education and Advocacy

For decades, Alberta’s economy was dominated by fossil exploitation tapping the world’s third-largest oil reserves behind Saudi Arabia and Venezuela. A crash in oil prices and imploding global demand (due to the COVID-19 pandemic) have taken a toll on Canada’s oil industry.

As of 2018, the US Oil and gas industry employed 153,000 people. The U.S. fracking boom and 2014 oil price crash resulted in 53,000 jobs lost between 2014 and 2019.

But today, Alberta’s renewable sector employs an estimated 26,000 people (directly and indirectly), and analysts predict as many as 20,000 new jobs will come online by 2030.

So, what lessons can we glean from Alberta’s transformed energy sector?

According to education non-profit Solar Alberta, government-funded education, economic development and advocacy are key in supporting Alberta’s transition. Most postsecondary institutions in Alberta, including University of Calgary and University of Alberta, as well as technical colleges like the Northern Alberta Institute of Technology and the Southern Alberta Institute of Technology offer continuing education in renewables.

Government grants subsidize 30 percent of tuition cost for these programs.

Alberta’s industry organizations are also providing reskilling programs for tradespeople and professionals making the move into renewables. Solar Alberta enrolls upwards of 650 continuing education students a year – a clear sign of the need for skilled workers in both the trades and engineering.

Advocacy group Iron & Earth was founded by oil sands workers to help Canadians shift from industrial trades to those more tailored to a sustainable energy future. The organization calls for a $110-billion federal

26

MARCH• APRIL2021 /// www.nacleanenergy.com

investment program to support a “green and prosperous” transition, helping energy workers gain the skills “to build the new, net-zero economy.” Its strategy combines community building, career and skill transitioning, fundraising, and demonstration projects to showcase success.

Where Alberta has Gone, Pennsylvania— and Others—can Follow

Energy-abundant Pennsylvania has been one of the leading producers of coal for over 200 years. It is the third largest supplier of coal and electricity in the country. Pennsylvania was also one of the first states to advance an alternative energy portfolio standard to incentivize its renewable sector.

Analysts estimate the state’s clean-energy market represents a $16 to $20 billion investment opportunity, with 72,000 potential jobs in energy efficiency and renewables. Clean energy jobs in the state grew by nearly 7,800 between 2017 and 2019, while coal, natural gas and nuclear industries saw losses of nearly 2,500 jobs over the same period.

In 2019, Pennsylvania Governor Wolf signed executive orders establishing the first statewide goal to reduce greenhouse gas emissions—mandating a 26 percent reduction of net greenhouse gas emissions by 2025 (from 2005 levels) and an 80 percent reduction by 2050.

The Special Shine of Solar

Solar has a major role to play as Pennsylvania creates its renewable energy future. Drivers like community solar programs are creating opportunities—especially in construction, hospitality, health care, and other sectors hard hit by the pandemic. According to a recent Penn State study, community solar would create 12,000 jobs and generate a $1.8-billion economic impact.

Again, Alberta has lessons to share. The province has committed to phase out coal by 2030—opening the door for solar and wind to play a larger role. Analysts predict that 83 percent of the utility-scale wind and solar capacity built in Canada over the next five years will be in Alberta, with solar representing 1.8 GW by 2025.

Pennsylvania’s traditional energy sector workers are just as skilled, motivated and retrainable as Albertans. Harnessing their experience, commitment and skill will drive solar success in the Keystone State just as it has in Alberta.

The regions’ similar climates and topographies mean that solar design and operational experience gained in Canada is imminently transferrable. While not as extreme as Alberta, Pennsylvania experiences harsh winters—with up to 100 inches of annual snowfall and temperatures as low as 19°F (-7.2°C).

GP JOULE /// www.gp-joule.com

The Know -How to Turn Experience into Excellence

When developing solar projects in regions that are transitioning from fossils to renewables, it’s smart to choose an EPC partner with experience leveraging the skills in oil and gas construction.

Both sectors face similar challenges. The work is often done in remote sites, sometimes in frigid conditions where frequent warm-up breaks are a safety necessity.

And both face the challenge of keeping teams motivated in cold and adverse conditions.

PV and oil and gas draw on common trades, like framers to assemble racking structure, welders for adjusting steel foundations elevations, electricians and others.

They use similar construction equipment, and both involve ground foundation and disturbance civil work requiring specialized training. When building utility-solar projects, EPCs with the right know-how can gain efficiencies using crews from the fossil fuel sectors with experience in large-scale construction.

The safety and training culture, which is intensive and well-developed in oil, gas and coal plant construction and operations, can elevate safety standards and practices across utility-PV projects.

TerraSmart’s ground screw solution supports over 3.5 gigawatts of tracker and fixed-tilt solar systems in some of the toughest of soil conditions in the U.S.

Building on a Strong Foundation

Developers looking at projects on rugged terrains and harsh environments - whether in Alberta or the northern U.S—can benefit from racking and tracking technologies built for such conditions. Products designed for reliability in extreme conditions, using structuralgrade materials with superior galvanizing, can offer unique advantages. Trackers and fixed racking with customizable foundations, including helical piles, driven piles or ground screws options, offer flexibility to install reliable solar assets on any terrain.

Alberta has shown that moving away from oil and gas opens the door to clean-energy jobs and economic growth. Developing and building profitable PV projects with partners experienced in transitioning economies can accelerate the transition to a brighter future.

Highly compact inverter for direct feeding into the medium-voltage grid

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE have developed an inverter based on new types of silicon carbide (SiC) transistors with high blocking voltages so the inverters can be connected directly to the medium-voltage grid. The high control dynamics of SiC inverters can take on grid-stabilizing tasks and act as active power filters to compensate for harmonics in the medium-voltage grid. SiC inverters can achieve high power densities, resulting in a compact design. As part of the project SiC-MSBat, medium-voltage inverters with high-voltage SiC power modules for largescale storage and system-serving distribution grids, a 250kW inverter stack was developed for feeding into 3kVAC grids. Here, 3.3kV SiC transistors are used with their low power losses, so the inverter stack operates with a switching frequency of 16kHz. The high switching frequency provides savings on the passive components, as these can be dimensioned in a smaller format. The inverter features its active liquid cooling with a synthetic ester as cooling medium. This medium is pumped through the inverter and cools both the transistors via a liquid heat sink and the filter chokes, which are housed in a closed tank. At the same time, the cooling medium for the filter chokes serves as an electrical insulation medium, allowing the filter chokes to be made even more compact. The inverter achieves an efficiency rate of 98.4% at rated power. The design of the inverter stack allows modular interconnection of multiple stacks to achieve system outputs of several megawatts.

Battery-less off-grid solar system design guide

CyboEnergy, Inc. has released a BatteryLess Off-Grid Solar System Design Guide. This guide will help customers and installers design off-grid solar PV water heating, zone cooling and heating, and electrification systems. The Guide illustrates how to use solar PV water heating to store energy in the form of hot water. It uses an off-grid PV water heating system, where a CyboInverter H model is connected to 4 solar panels and delivers solar energy to the lower heating element of the water heater. The temperature setpoint for the lower element can be purposely set much higher than the upper element. This way, the upper element that consumes grid power does not turn on unless a lot of hot water is used within a short period of time. Packaged PV water heating systems with OG-300 certifications are available through CyboEnergy’s strategic partners. It also shows how to operate an off-grid system with no batteries by using an AC assisted off-grid solar system that can run 120V loads. With assisted AC input power, the system can run AC loads 24/7 with solar power, grid power, or combined power.

It allows users to take major loads off the grid and avoid the cost and potential curtailment of an on-grid solar system.

CAB Solar Continues Innovation IN 2014 CAB SOLAR, the solar product production group for the Cambria County Association for the Blind and Handicapped, entered the grid-scale solar plant cable management market. Their patented, innovative above ground messenger wire cable management system was a paradigm shift for the industry and has helped to increase the efficiency of installation and lower the overall cost of solar power.

CAB continued to build on this innovation in cable management and introduced its one-of-a-kind Integrated Grounding above ground messenger wire system. This system provides the same above ground cable management but adds the game changing use of the messenger wire as an available EGC or GEC. Saving even more labor time and product cost.

CAB’s newest innovative solutions are hangers designed to hang off of the torque tubes in tracker systems, or even a carport structure. With designs to accommodate many tracker systems, these hangers are designed for long life and easy installation.

The Integrated Grounding system from CAB Solar is also being refreshed.

In addition to the routine addition of new hanger designs, CAB is introducing #2 equivalent grounding messenger wire for use with systems that need the added grounding capacity. Also available is a new #3 equivalent messenger wire that is slated to replace the current offering. The new addition uses slightly less copper while maintaining its #3 equivalency which results in an approximately 10% lower cost.

To aid in the innovative application of CAB’s products, they provide engineering support in the form of reports on the electrical properties and structural properties of the system and have an updated white paper from Bill Brooks that goes into some recent changes to the NEC.

CAB Solar continues to innovate.

Flexible and conforming bus bar connections

Mersen’s BusFLEXX flexible and conforming bus bar connections allow for connectivity of cables to bus bars, electrical/electronic components to bus bars, and even bus bar to bus bars wherever there is a need for mechanical gap tolerances and/or thermal compensation. The connectors can have static or +/-1mm dynamic properties, up to three rotational axis (X,Y, and Z), and provide cost effective yet long lasting connection methods. Mersen design engineers can work closely with customers to solve their specific design needs for custom-made conforming connectors. In addition, connectors can be designed with a certain amount of flexibility and spring tension, reducing the harsh effect of vibration/harmonics on hard connections.

Solar energy and money saving device

Con Edison is offering, free of charge, a device that can save upwards of $1,000 for a residential customer installing a new solar array. The Smart ConnectDER, built by ConnectDER, Con Edison’s partner on the project, allows the customer to avoid the cost of upgrading the circuit breaker panel. It also eliminates the need for excessive electrical boxes on the side of the home.

The Smart ConnectDER is an adapter that uses the electric meter socket as a point of interconnection for solar power. It fits on most electric meters and works for solar arrays up to 15kW, meaning nearly all residential solar projects. In addition, on homes where the meter socket is on an exterior wall, the installer does not have to enter the home to connect the solar to the home wiring. Smart ConnectDERs are simple and versatile.

A solar contractor who wants to use a Smart ConnectDER for a customer’s interconnection would send Con Edison a photo of the meter to confirm that the meter can accommodate the device.

Terminal block modules

The new RockStar ModuPlug terminal block modules with PUSH IN connection technology re-invents control cabinet wiring. The terminal solution in the connector frees up space in the cabinet and reduces installation time. Using the individual modules, combine all the necessary functions for power, signal, data, and pneumatics transmission in a single interface. The modules reduce the amount of space required and cut costs.

The frames and modules can be installed and integrated into HDC housings with the IP65 and IP68 protection classes. RockStar ModuPlug can be used in existing applications without the need to make system adjustments.

The halved pitch size allows twice the number of module slots in the frame. The reduced pitch separation creates more functionality in the same installation space. The design of RockStar ModuPlug offers several benefits, a two-point fixture allows assembly and disassembly without tools. The fixed locking position provides for stability and fast and easy assembly.

Incorrect connection is avoided through special round and rectangular coding. The RockStar ModuPlug Online Configurator enables fast and easy compilation of frames, modules, contacts, and accessories using drag & drop.

A new generation of roof attachments

SnapNrack’s new SpeedSeal Technology featuring SpeedSeal Foot for the Ultra Rail Roof Mount System and SpeedSeal Track for the RL Universal Roof Mount System have an innovative design that incorporates flashing reliability into a single attachment by using Lag Driven Sealant Technology. These new SnapNrack SpeedSeal products, SpeedSeal Foot and SpeedSeal Track, speed up the installation process by allowing installers to lag straight to a structural member with no in-between components, and eliminates damage to shingles from the installation process.

The simple install process consists of locating a rafter, filling the sealant cavity and securing to the roof. The SpeedSeal Technology takes over, compressing sealant into the cavity, shingle surfaces, and lag hole, as the SpeedSeal Foot or SpeedSeal Track is secured to the rafter. The 100% waterproof solution provides a lasting seal and passes UL 2582 Wind Driven Rain Test and ASTM E2140 Water Column Testing standards.

Both SnapNrack SpeedSeal Foot and SpeedSeal Track save installers time on the roof with less parts and less tools, while maintaining the integrity of the shingles. SnapNrack’s tradition of a single tool installation is carried on in the new SpeedSeal Foot and SpeedSeal Track designs with the same ½" socket, that is the standard for all components of SnapNrack’s mounting systems.

“Stop installing your bifacial solar panels on racking with a wind deflector!”

UNLOCK THE TRUE POWER OF SOLAR

W

hen the first Single Axis Trackers (SATs) came in operation around the world, over four decades ago, they did not immediately get adopted by the Solar Industry. In large part because there was no Solar Industry in the eighties, but also because of unknowns such as aging, reliability, and maintenance costs.

Opsun Systems, SunRail™ bifacial flat roof racking, by SHEA Electric

Even if the extra yield was appealing (along with the even more alluring increased Return On Investment [ROI]), the increase risks kept system owners and investors away from this technology for several decades, until all the elements of the puzzle came together: price, reliability, availability, contracts, insurers, installers, etc.

Another mistake perhaps is that developers, system owners and investors often imagine their projects and write their contracts for Watt peak capacity (power), instead of electricity generation (kWh), and thus incentivizes EPCs to use a low-cost racking with a wind deflector that will reduce the project cost in $/W, but at the same time prevent a 10-20% increased annual production possible with bifacial panels, thus impoverishing the system owner.

The same is happening with bifacial solar panels.

The Revolution of Rooftop Bifacial

Bifacial solar panels, a new technology in the eighties, is mainstream today for ground-mounted solar, but strangely absent from rooftop system. Why? Just like SATs, rooftop bifacial systems promise increase yield and return on investment, but just like any new technology, paradigms must be shifted around to unlock its value.

Savvy solar developers, including some roofers, now target clients needing a new roof, and package the roof as part of the “energy generating asset”, claiming the Investment Tax Credits (ITC) and accelerated depreciation on a portion of the roof value. Then, leveraging the reflectivity of white EPDM or TPO roofs (up to 80%!), they benefit from bifacial solar panels at almost no cost premium to produce an easy extra 10% yield with bifacial solar panels still tilted at the standard 10 degrees.

On bifacial solar panels spec sheets, an ominous “10%” extra bifacial energy is often stated, along with an even more gloomy “20%” or “30%”, all this without any explanation on how to achieve this extra yield.

To allow such financial structure, these system developers, owners and investors now request bifacial panels to be installed on a bifacial-optimized solar racking.

Now that bifacial solar panels are sold at approximately the same price as equivalent quality monofacial solar panels, an astute solar developer, system owner or investor shall ask “how can I achieve this 10-20% extra yield”.

As bifacial panels become more accessible, system owners and investors looking to bank on bifacial solar panels’ extra yield will prefer rail-based racking that protects solar panels from degradation, and that don’t use wind deflectors.

“Stop installing your bifacial solar panels on racking with a wind deflector!”, shall answer the bifacial solar panels specialist.

Bifacial solar panels require space under them for light to bounce and reach the backside of the solar modules. Panels must be installed in the landscape orientation, elevated at least 10” from the roof at the front, tilted as much as possible (10° and up), and no wind deflector or rails must be installed underneath.

Open racks without wind deflectors will also cool the panels better, usually increasing yield by an additional 2%. Anchored systems are often preferred to ballasted systems, as they block less light from reaching under the panels.

History repeats itself

Interested in unlocking the full potential of bifacial panels, as stated on their spec sheet? Contact us to learn how to optimize your flat rooftop bifacial solar system and obtain better yields. Now that all the pieces of the bifacial solar puzzle have come together, the time is ripe to step into the bifacial rooftop revolution, and reap the rewards.

Just the same way early adopters of SATs harvested increased revenue.

Dealership outshines the rest with Solar Carports BAJA Carports builds a beautiful carport solution for Texas Mercedes Dealership to generate power & protect from hail in just 28 days

2019 Solar Builder Nominee: BAJA Carports Mercedes-Benz of McKinney McKinney, Texas | 787 kW Today's car dealerships are looking for ways to improve their competitiveness. The cost of power, competition from online car buying, and escalating insurance premiums due to vehicle damage and deductibles are among their biggest challenges. One Texas car dealership has discovered that carports equipped with rooftop solar power address all three of these challenges while also benefiting the environment—and providing them with predictable and stable future power costs.

The main motivation for this solar power carport installation in McKinney, Texas, a suburb of Dallas, was to protect the dealership's high-end car inventory from hail. It was completed last April after three months of construction. Using a solar carport structure to protect their inventory gives car dealerships, like this one in Texas, the ammunition to potentially negotiate better rates and deductibles with their insurers.

The solar carports produce 1.089 megawatt (MW) hours of solar power annually and offsets 1213 metric tons of greenhouse gas. This is the equivalent of over 136,000 gallons of consumed gasoline or the annual power consumption of 190 homes. They are offsetting 78 percent of their power consumption with this solar installation. Their power costs are nearly eliminated, with a potential payback on the solar installation in five years or less.

In terms of curb appeal, the unique and attractive curved design of this carport, which encompasses the dealership's showroom and service building, complements their inventory and provides a shaded and comfortable environment for customers. It acts as an extension of their showroom floor where customers can walk around out of the sun and make their way into the dealership's VIP lounge. The carport is also equipped with solar-powered canopy lighting to illuminate the inventory late into the evening.

Baja Carports provided structural design, components, and installation on the project. Their team of in-house engineers to design the carport configuration. It features Baja's TS radius beam solar support system manufactured from pre-fabricated steel. The solar panels are attached directly to the structure's framing system or its rooftop decking, which was a design challenge since solar panels do not bend nor are their frames curved.

According to Baja Carports, the structure's curvature made for a challenging solar panel installation.

“The current design was born out of necessity to not design too tight of a radius so that solar modules could be installed. The outcome was a slight curvature, which works for solar modules and provides a unique look,” says Baja Carport’s Director of Operations Paul Cerejo.

Baja Carports was able to deliver and install the solar carport structure using a designated staging area and installing the carport structure in three phases with eight crew members in just 28 days. There was very close coordination with dealership management and a dynamic situation where the staging area was diminishing in size on a daily basis.

“Working at a high-end dealership, which cannot shut down for installation, while keeping their facility in operating condition is always a complex task,” says Cerejo. “Coordination between our installation crew and the dealership's sales department was vital.”

Outdoor lots at car dealerships are common for storing and displaying their inventory. Therefore, there is a constant need to protect that inventory from destructive weather like hail, as well as direct sun, rain, and snow. Solar carports are a perfect solution.

Wings Battle Blades

by Dr. Sara Weaver

Evoking a range of emotions, from awe and wonder to misunderstanding that can lead to fear, bats are fundamental to our environment. In fact, according to studies noted by the U.S. Geological Survey, the value of bats in the U.S. is estimated to be “worth over $3.7 billion per year, and possibly as much as $53 billion. This value does not, however, take into account the volume of insects eaten by bats in forest ecosystems and the degree to which that benefits industries like lumber. It also doesn’t take into account the critical importance of bats as plant and crop pollinators. So the actual monetary worth of bats is far greater than $3.7 billion per year.”

As the global human population continues to grow, so too will our energy demand. How we satisfy that demand will greatly affect the global bat population. Traditional sources of energy, such as oil & gas, as well as coal can already have negative impacts on the environment – notably pollution and contributing to climate change. The increasing need for renewable and more environmentally friendly energy resources, such as solar and wind farms, means that those installations are creeping further and further into wildlife habitats.

An especially glaring and distressing unintended consequence of wind energy development has been bat fatalities at wind turbines.

Bats are primarily killed by wind turbines when struck by the rotating blades during nights of low wind speed. Impacts to certain bat species, such as the hoary bat, are of great concern because they are unmatched by any other human caused sources of direct mortality. Bats are a vital component of our ecosystem.

Every bat matters. The United States is home to dozens of species of bats that feed exclusively on insects. The loss of one or two bats may not seem like a big deal, but when you consider that the northeast part of the country has lost a million of these animals – that translates into around 1,000 metric tons of insects left alive to damage crops like cotton and corn. In turn, the agricultural industry loses their source of free pest control and, along with a potentially heavier reliance on artificial means of keeping our food supply safe, higher costs are passed on to the consumer. Additionally, while many of other species are pollinators and seed dispersers, they also serve as important prey for animals such as owls and hawks.

The wind energy industry recognizes the importance of these unique animals (the only mammals that can fly!) and have been working towards finding solutions. Currently, the most common way to reduce fatalities is curtailment of wind turbines on low wind speed nights, when bat fatalities are at the peak in summer and fall. Unfortunately, this also lowers energy outputs, which means non-renewable energy sources must pick up that slack, reducing the benefits of wind energy towards slowing climate change. Because of this, researchers and industry have been looking for solutions that will allow for wind turbines to function normally.

Ultrasonic acoustic deterrents - devices that project frequencies of ultrasound within the hearing range of bats to make the air space around a wind turbine uncomfortable - have become the focus of these efforts and offer promising results.

Many bats navigate using echolocation, emitting high frequency sound waves that bounce off obstacles helping them “see” their surroundings. The frequencies of these sound waves vary among different bat species. A frequency “jammer” mounted on a nacelle might steer certain species away from danger, but not others. This necessitates an extra effort on our part to learn the different languages bats use so that we can effectively warn tthem and protect them from harm.

A recent study found an ultrasonic acoustic deterrent significantly reduced fatalities of the Brazilian free-tailed bat by 54 percent on average, and by 78 percent for hoary bats. However, it wasn’t effective enough/able to deter all species. To help solve this information gap, the U.S. Department of Energy’s Wind Energy Technology Office is funding a project to learn why we see differences in effectiveness among species. The goal of this effort is to improve the design to be more effective. If successful, this technology could become a new solution the wind energy industry, and bats, have been looking for.

Offshore Success Relies on Strategic Maintenance

by David Futter

Figure 3: Specialist condition monitoring experts perform ongoing data analysis (Credit: adobestock / Gorodenkoff )

WHEN IT COMES TO WIND TURBINE

maintenance, owners’ goals can generally be summarized as follows: predict faults early to reduce unplanned downtime, increase overall profitability, and extend the lifecycle of the turbine. Fault prediction, the most essential element of the maintenance planning process, is facilitated by smart, cloudbased Condition Monitoring Systems (CMS).

CMS enables wind park owners to implement a knowledge-based maintenance strategy; a careful combination of reactive, preventive, and predictive maintenance. Reactive maintenance is simply waiting for a part to break down before replacing it. Preventive maintenance estimates interval times between repairs based on historical data. Predictive maintenance uses real-time data to predict faults before they occur.

An appropriate combination of the three approaches depends both on the affected part and the criticality of the fault. It also requires the ongoing acquisition and analysis of vast amounts of relevant data. Data is collected by specialist CMS hardware. In order to derive useful knowledge, however, it must be stored in a location accessible for analysis. This analysis is what converts raw data - first into information, and then into knowledge upon which predictive maintenance decisions are based.

The collection of CMS data in wind power takes place via internet-enabled measurement systems with a circular maintenance process (figure 1). This process begins with the establishment of a baseline, whereby CMS data is then periodically collected and reviewed for any deviations from the baseline. Should changes or alarms occur, then appropriate maintenance can be planned and carried out. The final step is to then reestablish a new baseline, following maintenance actions.

Due to access restrictions, the cost of repairing a wind turbine is often significant. When turbines are located offshore, those costs are amplified. Offshore maintenance requires complex logistics to access the turbine, as well as safe weather conditions for the offshore transfer of the maintenance team.

To reduce these costs, turbine owners must be able to plan and combine maintenance actions. Early detection of a developing fault through smart Condition Monitoring provides the solution. Early warning signs become visible through a combination of IoT-enabled hardware and cloud-based software.

When it comes to hardware, a variety of sensors collect and collate data to a local CMS edge device, which performs some post-processing before transmitting data to the cloud. This integrated approach ensures that data collection is completely synchronized, avoiding the need for multiple connections. Any bottlenecks in the data transmission process are thereby removed, which also improves cyber security. Transmitting data via one secure link (as opposed to a multitude of individual systems) offers turbine owners a safer alternative.

Once the edge devices have delivered data to the cloud server, it can be further processed by CMS monitoring software. The data is then used by analysts to search for trends and anomalies, and to inform maintenance teams of any required action. Results are shared in the cloud server, making them accessible online from any authorized device. Maintenance teams are then better able to plan repairs, including ordering the correct parts and setting an optimized time schedule.

There are multiple benefits of employing IoT measuring devices together with cloud-based analytics.

First, any control-relevant CMS data is shared locally with the turbine control system, streamlining the application of collected data. Second, IT overheads remain low due to fewer connections and less external data.

As well as improvements to cyber security, all data becomes available in one place, providing a holistic overview of not only individual turbine performance, but the performance of every turbine in the fleet.

Results are available anywhere, anytime, which enhances communication between analysts and maintenance teams. Finally, cloud-based systems allow turbine owners to outsource specialist tasks, like Vibration Analysis, to third party experts.

MARCH• APRIL2021 /// www.nacleanenergy.com

Figure 2: Service engineer on the way to make repairs (Credit: Monty Rakusen, gettyimages) Many wind park owners choose to outsource CMS processes, particularly data analysis, due to the economies of scale available. Through certified Condition Monitoring centers, dedicated teams of trained specialists are available 24/7. With a constantly growing database from many connected turbines, these specialists can derive in-depth knowledge faster and more accurately than any individual park owner examining the performance and condition of single turbines.

In simple terms, this means turbine faults are detected and dealt with earlier, before they become significant and cause major damage. Working with independent experts also gives park owners more OEM independence, all while allowing site teams to focus on power generation and maintenance.

To begin Condition Monitoring, turbine owners must first define possible faults, or failure modes, and their impact on machine lifetime; smart CMS hardware can then be installed to specifically monitor these failure modes and provide relevant data to the cloud server. The actual monitoring and analysis can be outsourced to specialist third party providers.

Condition Monitoring is a constantly developing process; prediction accuracy increases as more knowledge is accumulated. The growing fields of offshore and floating wind offer a world of untapped data that will further improve maintenance strategies, deliver more accurate predictions, and help prolong the life of wind turbines.

New England Offshore Wind Top 10 takeaways

by Wayne Cobleigh

With a new year and a new pro-offshore-wind Biden Administration, no region of the United States may see as much OSW permitting, design, and pre-construction activity in 2021, as New England. Here are the top 10 takeaways on where the industry stands today, and what to expect in 2021.

1. State policies, legislation, and procurement efforts for renewable energy in New England are driving offshore wind market confidence, economic and workforce development, resulting in lower prices for offshore wind powered electricity.

Rhode Island continued to lead in 2020, with the announcement of a new procurement of 600 MW of offshore wind. Connecticut has committed to generate 20 percent of its electricity from offshore wind (the largest percentage of electric load of any state). Connecticut will boost its precision manufacturing base by adapting aerospace and cable manufacturers to produce offshore wind equipment.

Massachusetts expects that 5800 MW of offshore wind transmission can be connected before upgrades to the onshore grid will be needed. The New Hampshire Business Finance Authority has hired a Director of Offshore Wind

Industry Development, and set a goal of 600-800 MW of offshore wind. Maine has a floating turbine demonstration project, as well as a goal of doubling their offshore wind workforce by 2030. The result is improved market confidence.

2. Federal environmental impact permitting of offshore wind projects by BOEM will see a very active decade.

Eighteen projects have already been identified in the permitting pipeline from 2020 to 2030. Primary factors to address for permitting and siting are vessel navigation routes, especially New England’s fishing industries routes for lobster, scallops and fish, essential to New England’s economy. Marine mammals like the highly endangered North Atlantic Right Whale (with a population of less than 400) will also require ongoing protection. Developers have agreed to strict compliance practices in cooperation with environmental advocates. Delays on the initial permitting of the Vineyard Wind 1 project are creating a backlog concern for resource constraints in the supply chain. BOEM has 10 Construction and Operations Plans (COPs) under review in 2020, with five more expected.

3. States, utilities and ISO New England must plan for transmission and distribution system capital investments to construct a multistate transmission backbone.

This will help to reduce costly congestion and curtailments on New England’s existing power grid. Energy commissioners from Connecticut and Massachusetts addressed the need for the New England states to cooperate on grid planning for Wholesale Market Design. They will also need efficient power procurement methods to meet their aggressive renewable energy and carbon emission policy target dates coming in 2030, 2040, and 2050.

The current market structure is not ready for the transmission requirements of 100 percent renewable energy generation; Massachusetts, Connecticut, Rhode Island, New Hampshire, and Maine expect to collaborate on this topic to form a regional plan for addressing competitive offshore wind lease areas in 2021.

MARCH• APRIL2021 /// www.nacleanenergy.com

4. The next generation turbine is disrupting the industry with a power output of 13MW - enough to power an estimated 12,000 homes. This largest of turbines produces more electricity that translates to greater revenue, fewer turbines, and lower net installation and maintenance costs than the smaller turbines.

Vineyard Wind opted for these larger turbines, despite causing a temporary pause in the Construction Operating Permit (COP) approval process and their final due diligence. Financial close of this project is expected to be completed in the 2nd half of 2021, with an estimated 62 turbines (instead of 82 smaller turbines) beginning construction in 2022, to become operational in 2023. The Revolution Wind project is also expected to be operational in 2023. This move to much larger turbines will ripple throughout the industry supply chain, impacting manufacturing, turbine blade testing facilities, port development plans, foundation size, power pricing, and offshore lease auction awards made in the future.

5. Port Development is integrated into Offshore Wind Power Procurements. Economic development investments in ports will be shared between developers and the state and federal government, via public private partnership (P3) agreements.

Ultimately, the developers need to lease ports as their projects are approved. However, the ports will need significant due diligence and infrastructure investments to prepare these facilities for the extreme loads and logistics of offshore wind equipment. Currently, port development projects are underway with the Connecticut Port Authority at the State Pier in New London, Vineyard Wind is establishing their Bridgeport, Connecticut team and port facility; the State of Maine is investing in a port assessment study of their Searsport facilities; the State of Rhode Island and the federal government are investing in the Quonset Business Park, private developers and the state and federal government are planning to invest in the South Quay site in East Providence; and Massachusetts Clean Energy Center has

completed port assessment studies on the North Shore to add port facilities to their New Bedford Marine Commerce Terminal. These states are expecting to see good local jobs created in return for their investments.

6. Marine wildlife habitat conservation, marine mammal protection, and fishing industry interests are being emphasized and addressed in formal agreements developed by advocacy organizations and project developers.

The Memorandum of Understanding (MOU) developed by Vineyard Wind with Audubon and the Conservation Law Foundation is enabling the voluntary protection of sea turtles and North Atlantic Right Whales, through the establishment of best practices for noise reduction and prevention of entanglements. The Responsible Offshore Development Alliance (RODA) and the various New England State Lobstermen’s Associations are important stakeholders in ensuring that clean energy does not grow at the expense of the long-established fishing industry in New England.

The offshore wind industry will need to continue to be proactive on research to reduce noise from monopile installations and compliance with the Endangered Species Act, Marine Mammal Protect Act, and the MOU. Developers are focused on listening to stakeholders and active stakeholder engagement to advance the permit approval process. This engagement includes marine mammal experts, fishing industry advocates, native American tribes, government regulators, legal counsel for the stakeholders, and the public.

7. The siting of acceptable landfall locations for offshore wind cables will become more challenging, as more favorable landfall connection points in southeastern New England are taken by the first wave of approved offshore wind projects.

Offshore transmission can account for 20-25 percent of the capital expense of a wind farm. Transmission cable performance and risks of delay or operational failure impact 100 percent of the revenue from the wind farm. Offshore cable burial requirements are highly regulated to avoid impacting sensitive marine habitats. As offshore wind farms move greater distances from the shore, interest has begun in the use of High Voltage Direct Current (HVDC) cable systems, which can achieve a 1200MW capacity per cable bundle (significantly greater than cables currently in use). HVAC is preferred for wind farms within 60 miles from shore. HVDC becomes more effective at distances of 80-100 miles from shore; performance of these cables improves over greater distances.

8. Market confidence spurred investment in the first Jones Act compliant Service Operation Vessel (SOV).

9. Congress finalized and voted on a COVID-19 relief bill that included a 30 percent Investment Tax Credit (ITC) for offshore wind (OSW) projects in construction Jan. 1, 2017 through Dec. 31, 2025.

The final ITC rules for offshore wind reflect an increasing awareness of the industry, as well as the industry’s economic development importance to federal lawmakers.

This legislation also includes appropriations for the U.S. Department of Energy and provisions for the U.S. Department of Interior that will provide future growth opportunities for the offshore wind industry.

10. The US offshore wind industry will soon have an independently approved roadmap to efficiently guide professionals on best practices, safe designs, and orderly installations of offshore wind energy in the US market.

This roadmap will benefit everyone: technical practitioners, developers, regulators, and the public. Since 2017, over 300 volunteers have collaborated in five working groups to draft recommended practices by consensus for Offshore Wind Compliance Recommended Practices regarding (1) Maintenance (2) Floating Offshore Wind, (3) Metocean Conditions, (4) Geotechnical and Geophysical Investigations and Design and (5) Submarine Cables. The American Wind Energy Association (AWEA) Standards Organization - recently merged with the American Clean Power (ACP) Association in cooperation with American National Standards Institute (ANSI) - are reviewing draft Offshore Wind Compliance Recommended Practices documents. These were completed last year in preparation for public comment and publication by the end of 2021.

QUICK DECISIONS CAN OFTEN MEAN

life or death in remote locations like wind power farms, both on land and offshore. Having protocols, trained staff, and on-site medical support can help mitigate critical situations such as heart attacks or major traumas. While every situation is different, having specific protocol details written down can help most companies and personnel through them successfully.

In one case, a team consisting of a doctor and paramedic was providing contracted medical support services at a clean energy site on a remote island.

The team received a call about a 55-year-old worker complaining about chest pains. Within 15 minutes, the team responded and moved the patient to their mobile clinic to scan for an EKG, at which point they confirmed that the patient was, in fact, having a heart attack. Following the standard protocols for Advanced Life Support in remote locations established by the company and their consultant, the doctor contacted their topside support medical specialists for a consultation. The two doctors agreed on a course of action - the patient received a clot dissolving medication called a thrombolytic (in this case, the medication Tenecteplase) – which helped stabilized him until he could be airlifted to a hospital. Just 20

minutes after receiving the medication, the patient’s EKG was almost back to normal. The onsite medical team took four to six-hour monitoring shifts for the next 48 hours until the medivac could arrive to take the patient to the nearest hospital in Hawaii.

Heart attacks can lead to cellular damage around the heart, functional incapacity, or can cause an untimely death. Fortunately, the established protocols and access to virtually immediate care enabled this patient to fully recovered with no residual health problems.

After close monitoring, he was released five days later.

According to the onsite doctor, if this event had taken place on the mainland in the United States, the patient would have been rushed to an emergency room and then monitored in an ICU just as closely as he was offshore. Although a heart attack may not a be a common occurrence on many remote project sites, the protocols established by the clinical team ensured their patient survived.

Having someone onsite with a medical background to recognize symptoms and be able to treat them is hugely important in remote settings. Unexpected emergencies happen - without the proper care, the outcomes may not always be as positive.

Setting Up Protocols

When designing plans and establishing protocols, anticipating the worst-case scenarios is the best preparation. In the example above, protocols should be in place for every contingency: • What is the protocol for evacuation if a helicopter is not available, or weather conditions make it impossible to fly?

• Who has the proper training to perform first aid, safely move, and monitor the patient while waiting for help to arrive?

• Are there multiple people with the required training/current first aid to take shifts staying with the patient?

• Is the location equipped with a working Automated External Defibrillator (AED) and, if so, who is trained to use it?

Leveraging the expertise of an independent QHSE Advisor helps ensure that plans cover virtually all scenarios, and include the proper protocols, checklists, and communication plans needed to handle medical emergencies. In addition, these advisors can provide testing and training on a regular basis, both tabletop and locationbased scenario training. Regular testing improves not only improves effectiveness, but also identifies areas needing further training before an emergency arises.

Steps for A Successful Plan

The best approach to creating a safe and healthy work environment follows four steps: 1. Plan 2. Test 3. Practice 4. Use professional consultants and medical teams.

Take the time to develop a comprehensive health and safety plan. Anticipate the “what ifs.” Test the plan, and continually improve it. Seek out a medical services partner experienced in meeting the clean energy industry’s unique challenges, and offers a complete scope of services from planning to medical support and training. The smartest course of action is to work with a partner who demonstrates a robust understanding of the dangerous conditions under which a clean energy crew may operate.

Failing to Prepare = Preparing to Fail

The must-have checklist when setting up Lidar for offshore wind measurement

by Ameya Paseband

All around the world, offshore wind development is on the rise. With more wind farms being developed both in near-shore environments and deeper waters farther from coastlines, offshore wind is expected to constitute more than 20 percent of total wind energy installations by 2025. In fact, the U.S. alone has a technical potential of more than 2,000 gigawatts (GW), with developers committed to building projects delivering 26 GW along the east coast by 2035.

As offshore environments become increasingly popular for wind projects, so too does the use of lidar technology. Not only does Lidar provide the most quantitative and accurate measurement technique for wind energy applications, but its technology is simpler to deploy and maintain than established technologies.

It’s also less expensive.

MARCH• APRIL2021 /// www.nacleanenergy.com

By replacing met masts, lidar enables significant project development and operational cost reductions. In order to ensure the success of their projects, owners and operators need to know about the on-site logistics of offshore lidar setup. Here’s a brief checklist to get moving in the right direction.

Define the Goals and Select the Solutions

The first — and most important — step is to define the project goals. From site prospecting and wind resource assessment, to turbine power performance testing and wind farm optimization, understanding what you’re trying to achieve will help determine the application and lidar that best suits your project needs.

Lidar solutions include: • Scanning lidar provides a 3D offshore wind profile, with easy onshore or platform access and a typical operational range of 6 miles (10 km) up to a maximum range of 12 miles (19.5 km).

• Floating lidar is ruggedized and optimized for either integration into buoybased floating lidar systems. It can also be placed on fixed offshore platforms to measure on-site wind speed, direction, etc.

• Nacelle-mounted lidar is mounted on the nacelle of the turbine. It points upwind to measure wind coming toward the turbine, providing accurate power performance curves.

Knowing how you will meet your goals with the lidar solution you choose helps pave the way for many other logistics that need to be considered.

Timing

While there’s no standard timeline for offshore wind projects, moving an offshore project from development through planning, securing contracts, construction, and operation is a lengthy process that can consume at least five to six years. For lidar procurement and installation specifically, plan on several weeks of preparation because - regardless of the application - lidars are tailor made, not mass produced.

Consequently, timing is a crucial consideration for offshore wind farm development.

Additional Considerations

Serially produced powertrain

Training the Team

ZF Wind Power /// www.zf.com

Developers should also account for weather delays, transportation, wireless connectivity, and stable and sufficient power supply. These considerations are important for project managers who are new to lidar, but are generally out of the hands of the supplier.

Lidar users have to ensure the system operates well by testing onshore with the same conditions that the system will face at sea (same power supply, same connectors, etc.). Therefore, part of the on-site logistical process includes ensuring team members are trained to understand industry best practices regarding installations and deployments, as well as the capabilities of the lidar and routine maintenance operations.

In general, lidar training programs include both the theoretical and practical; a lidar professional visits customers to help them understand how to use and install the lidar, as well as assist with analysis of the incoming data. New customers must not only consider challenges surrounding the turbine, the layout of the wind farm, and the geography’s microclimate, but also how to aggregate, understand, and optimize performance based on the incoming data.

Because there are disparate lidars for different applications, the duration of the training varies. While buoy and nacelle lidars only require about two days for training and installation, scanning lidar is more complex and requires an extra day or two to understand. Regardless of the technology chosen, it’s important for at least four people to have a good understanding of the technology, its advantages, and its limitations in order to overcome any of the aforementioned logistical and operational challenges that may arise.

Lidar technology is driving the wind energy industry forward because it enables companies to go farther into the sea, measure higher and more accurately, scan larger areas, and choose the right turbine models. To benefit fully from this technology – and stay within project timelines and maximize project value - wind companies need to understand the early on-site logistics in getting offshore lidar set up properly.

ZF Wind Power and Vestas launched the serially produced EnVentus powertrain onto the wind market. With an integrated and modular powertrain design that includes main shaft, main bearing housing, two-stage planetary gearbox, and permanent magnet generator, the EnVentus powertrain guarantees an output of up to 6.0MW and is developed and tested at the facilities of ZF Wind Power in Lommel.

Harmony between wind energy and bats

Natural Power has launched DARC (Detection and Active Response Curtailment), a bat smart curtailment technology to simultaneously reduce bat fatalities and energy losses at wind farms. An acoustic monitor sits on top of the nacelle and listens for bat calls.

When it detects bat activity, it sends a signal to the DARC server where it is processed alongside other SCADA signals from the turbine and meteorological data. The server then decides whether the turbine should shut down or not. If it forces a shut down, the blades will slowly come to a stop before lying motionless for 30 minutes. If more bat activity is detected during this time, the turbines will continue to lie still for 10 minute increments until no activity is detected.

The turbines will then start up again.

This triple threat is accomplished with a glass fiber and ultrahigh-molecular-weight polyethylene (UHMWPE) shell, a composite yarn that has a strength-to-weight ratio 8 to 15 times greater than steel, and polyurethane coating. The thin, 13-gauge material delivers deftness without trading away its inherent cut-resistance. The nonsticky polyurethane coating on the palm and fingers features excellent grip, even against oils, fats, and greases, and can deliver enhanced puncture protection and abrasion resistance, all without adding bulk or reducing touch sensitivity. In addition, the glove’s uncoated back and wrist improves ventilation. A seamless and stretchable full knit wrist provides a snug fit and prevents dirt, debris, and cold from getting inside glove. Color-coded cuffs easily indicate glove size.

Unlocking complex wind sites

Deutsche WindGuard’s new ZX Complex Flow Solver (ZX CFS) is the result of a joint development with ZephyScience, supported by lidar OEM ZX Lidars. Fully based on computational fluid dynamics (CFD), ZX CFS identifies, quantifies, and resolves the relative differences between lidar and cup anemometer measurements witnessed in complex terrain. The Complex Flow Solver algorithm developed by Deutsche WindGuard is optimized for ZX Lidars’ wind field reconstruction. Incorporating results from a high-resolution CFD model, it derives a set of conversion factors. Applied to the volume-based wind data from Continuous Wave Lidar ZX 300, which samples 50 measurements points per second, these conversion factors produce single point measurements equivalent to those of a cup anemometer installed at the same location. ZX CFS even provides guidance on where to install the lidar initially to achieve the lowest possible uncertainties. Cloud computing delivers fast, transparent, and accurate results.

Safe, simple, and smart push-in wiring

IDEC Corporation has enhanced their HW series of 22mm switches and pilot lights, as well as the SJ/SU series of relay sockets, with new options for push-in wiring technology. The IDEC HW and SJ/SU series uses true tool-less pushin technology. There are no screws to torque or tighten. Wires can be removed by pushing down a small orange release pin with a screwdriver. Wiring can be performed by workers of any skill level, and wiring time is reduced by about 55% compared with conventional screw terminal connections. Constant springloaded tension on the wire maintains a reliable connection and improves vibration resistance. The entire push-in structure is designed as finger-safe so workers never touch the conductors.

Push-in contact blocks are compact, improving working space inside a panel and potentially enables enclosures to be downsized. Connections are angled to facilitate wire entry, and the contact blocks feature a handy test point for insertion of a multimeter probe. Both switch contact block and relay socket electrical connections are rated IP20 finger-safe.

Pliers with a staked screw

The new P-Series Pliers from Snap-on Industrial are manufactured with a staked screw that is compressed to a tolerance at the screw joint to prevent it from backing out during use. This design feature greatly reduces foreign object damage (FOD) concerns, making it suitable for use in aviation, power generation, natural resources and any other critical industries. The staked screw is just one of many features and benefits of the new P-Series Pliers. The screw joint minimizes friction and maximizes jaw alignment for wide openings. Manufactured with ball-bearing grade alloyed steel, and hardened to 42-46 Rockwell C HRC, the P-Series Pliers are designed to withstand greater impact while performing in demanding work environments. Additionally, the internal torsion spring returns the pliers to the open position, keeping the tool ready for work while minimizing hand fatigue. Thirteen models (five cutting, eight holding) of the P-Series Pliers are available. The cutting models produce feature sharp, clean cuts for up to 200,000 cycles. The holding models are designed with precise serrations for sure gripping of delicate materials.

Strong, light, recyclable wind blade option

SABIC introduced LNP COLORCOMP WQ117945 compound, a material based on nanotechnology that facilitates efficient production of polyethylene terephthalate (PET) foams for core materials in sandwich structures. This new compound improves control over nucleation and cell growth, resulting in decreased cell size and uniform, narrower cell size distribution. These attributes can reduce the foam’s weight by minimizing resin uptake in sandwich structures. It can also potentially improve shear strength/strain properties for better fatigue performance. Enhancing PET foams with SABIC’s new LNP COLORCOMP compound can address the evolving needs of multiple industries, including marine, building and construction, packaging, and wind energy. SABIC’s LNP COLORCOMP WQ117945 compound can significantly reduce foam cell size, while decreasing cell size disparity by a factor of up to five.

These factors help to reduce resin uptake by the foam during composite manufacture, resulting in a lighter-weight wind blade. PET foams offer versatility in the design and shaping of wind blades, and also offer stable supply, cost-effectiveness, consistent material properties and much less resin uptake.

Transportable Electrons Can Jump-Start Renewable Energy Development in Emerging Markets

by Ian Hatton

THE WORLD IS WAKING UP TO THE FACT

that the climate is changing – and unless there is a significant reduction in carbon emissions, our planet will become uninhabitable for human life. While cutting back on fossil fuels helps, key steps are also being taken to rapidly scale up renewable energy across the world. According to a recent analysis, governments, companies, and households worldwide invested $500bn into new renewable energy capacity in 2020 – a great achievement in the midst of a global pandemic.

Regardless of the increased pace of the transition to clean energy, it’s barely making a dent in global carbon emissions.

In order to increase the rate of decarbonization, the industry must overcome the grid as a key obstacle to development of clean energy projects. This is a particular problem in emerging markets with the greatest potential resource and the most to gain from decarbonization. Though self-described as one of these developing countries, China is already on its way; it has managed to install 95.81 gigawatts capacity of on-grid wind power (90 times of that for 2005), as well as 7 gigawatts offshore (as of the end of 2019), and has reported to the Paris Accord that it plans to achieve a 20 percent reduction in use of fossil fuels by 2030.

High resource, no route to delivering it

Offshore wind is rapidly emerging as a crucial source of clean energy at a global scale. This is owing to the consistent, strong wind resource that can be found along many coastlines and further into the ocean. However, these projects typically require direct access to the grid to enable energy to be transported from offshore sites to population centers on land.

As such, much offshore wind development to date has been limited to wealthier nations that can afford to install and update grid infrastructure. Many countries new to utilityscale renewables simply do not have this grid infrastructure in place, nor do they have the means to scale it up to handle the

94

MARCH• APRIL2021 /// www.nacleanenergy.com

capacity required for new offshore projects.

In order for an offshore wind farm to be developed in emerging renewables markets, billions of dollars of grid infrastructure must also be built. This level of investment increases the cost of the project to the point where it is often no longer economical.

This often results in many of the prime sites for wind energy projects in terms of resource being disregarded due to a lack of grid infrastructure. The cost of updating grid infrastructure could result in higher emissions due to continued dependence on coal and oil for decades to come - despite the enormous offshore wind resource along the coasts of many emerging markets.

Bypassing the grid

In order to overcome these challenges, it’s crucial for the renewables industry to consider new technology and strategies to bypass the need for direct grid connection altogether.

“Transportable electrons” - energy stored in a form that can be physically transported via existing infrastructure such as tankers, trucks, and repurposed pipelines - are the key to building projects where the best resource is, without relying on costly transmission upgrades or development A number of technologies can enable transportable electrons. Many companies are already starting to invest in the production of hydrogen via electrolysis powered by offshore wind. This green hydrogen can be shipped in repurposed oil tankers, or transported to land via natural gas pipelines. Transportable electrons will springboard offshore wind as a renewable energy source in emerging markets by lowering the investment required by the state for grid development.

SOLAR + STORAGE: Today’s Progress, Tomorrow’s Promise

Hybrid projects, multiple revenue streams

Green hydrogen production can also enable the “clean” generation of several other commodities – ammonia, brine, clean water, and hydrogen as fuel - and enable diversification of revenue.

For example, hydrogen is a key component for the production of ammonia, which is used in the agriculture, transport, and manufacturing sectors. As pressure increases for these sectors to reduce their sizeable emissions footprint, cleanly-produced ammonia will be in even greater demand.

Ultimately, this diversification of revenue can boost the returns of hybrid offshore wind-to-hydrogen/ammonia projects. It can help bring down the cost of energy to the point that offshore wind is financially viable in areas with unsuitable grid infrastructure.

If we strive to bypass prohibitive costs involved in the grid aspect of renewable energy development, ensuring that excess energy can be stored and transported to where it is needed most, we can step closer to a decarbonized economy.

Don’t Dig There

Cutting down on line strikes (and related accidents) in renewable energy development and construction by by Corey Brecht

Damages add up when you cut corners.

The world needs renewable energy now more than ever. Fortunately, renewables are here to stay, but ironically, in the pursuit of clean energy, developers run the risk of damaging existing underground power infraastructure. The risk is real, and the potential for damage — to people, capital, and the environment — is serious.

Wind towers are being erected, collection lines are being trenched, and solar panel mounts are being driven into the ground. In the world’s attempt for advancement and expansion of renewable energy, hundreds of thousands of acres of land will become disturbed. In the past year, 18 percent of all electricity generated in the United States was linked to renewable energy sources. Within the next ten to fifteen years, companies will begin breaking ground to create even more opportunities for the renewable energy sector, including solar panel manufacturing, wind turbine fields, additional water-generated power plants, and even electric vehicle (EV) charging stations. However, in order to start that journey, subsurface contractors will need to scan and make sure each location is safe to begin building. This is no small task: in 2019 alone, there were 532,000-line strikes, with a utility strike happening every 62 seconds. The last two decades saw these accidents directly (and indirectly) result in over 30 billion dollars-worth of damage, 2,400 injuries and over 400 deaths, Fortunately, despite the bleak outlook of these staggering statistics, there’s an answer to the question, “How do we mitigate these risks?” And that answer is called the “SIM Method.”

First and foremost, Subsurface Investigation Methodology, or SIM, is a process all successful subsurface inspection companies must follow in order to create a safe and secure job site. The SIM method entails a set of steps to prevent accidental and unwanted damages when drilling or digging underground.

Companies that utilize the SIM method help prevent these costly expenses by scanning concrete, locating underground utilities, and video inspecting subsurface pipes. How does that relate to renewable energy innovations?

MARCH• APRIL2021 /// www.nacleanenergy.com

Let’s say you own your own subsurface/utility locating business. You get hired by a company in the Renewable Energy Sector for an expansion involving solar energy, wind energy, or EV Charging Stations. In solar, for example, chances are you’d be installing a photovoltaic power station, applying a canopymounted solar panel to distribution/transmission lines, or simply building a rooftop solar panel source for a residential home or commercial business. Before you can begin excavating, you must perform utility locating and mapping services to get a better understanding of the underground set-up. “Can’t I just call the 811-number, saving time and energy, instead of hiring a subsurface contractor?” That’s a good start; calling 811 should always be the first step in the process, but there are quite a few more stages you’ll need to follow to ensure a safe job site. You must research records, walk the site to find any above-ground indications of utilities, and review any existing drawing or maps.

Pictured above is the detailed step by step SIM process to visualize how you should handle pre-construction business.

Every industry has set standards they must follow to ensure success. Renewables adhere to the same processes. Whether a wind farm, EV charging stations, or hydropower — each project requires careful, detailed excavation to ensure that the surrounding area, crew members, and local residents are protected from potential harm. If you begin to take shortcuts, trying to cut corners on a project, you run the chance that you’ll become a part of the wrong side of statistics, resulting in another billion dollars-worth of damages, or worse, another neglectful death.

Applying a filter (SIM) to a potential subsurface contracting job prevents companies from accidents like line strikes.

Not following the SIM process prevents lower end companies from safely scoping out a job site, which has been proven time and again to result in costly, unforeseen damages, and even death.

Subsurface inspectors are in the business of helping in a safe bubble of protection, something the rapidly expanding Renewable Energy Sector needs in spades. If you want to provide a seamless experience for construction crews, while growing your profits, then you’ll utilize a SIM qualified subsurface company before breaking ground; much like a secret network of tunnels, our connection and utility lines run rampant underneath the cities and towns of our country, providing power to the homes and businesses of millions of Americans worldwide.

With the combined vision to provide safe, clean energy to everyone across the US, it’s vital to provide an accurate set of information regarding underground facilities and pipelines during the construction process. Given the costly damages, both financial and physical, that come with cutting corners on an important project, would you be willing to take the chance on things going wrong?

Protection is what matters the most when venturing into unknown waters. Subsurface inspectors and utility locators provide the security that allows booming industries to branch out, grow, and succeed.

Corey Brecht is Market Segment Renewable Energy Leader at GPRS, which specializes in utility locating. At its dedicated safety training center, GPRS requires every project manager to complete an extensive training program before they can perform field services on a job site.
