Signs of Change

by Roger Duncan and Michael E. Webber

Most of the energy conversions in our economy are for buildings, transportation, and the generation of power. Based on out observation over the past several years, here are some technology trends that we believe will shape the future of these economic sectors.

The intersection of information, technology, and energy conversions will drive the future - the overarching trend being the movement towards energy efficiency. We call this the Energy Efficiency Megatrend. It’s not limited to what is conventionally thought of as “energy efficiency technologies”, but more of a fundamental trend that impacts all technology.

Technology is achieving ever increasing efficiency in energy conversions through a surge in information intensity; this shows up in materials technology, design and engineering, automation, and now artificial intelligence.

We see at least three consequences of this megatrend.

First, buildings, transportation, and the power grid will meet their functions with less material, less energy conversion, less motion, and in less time. Materials will become lighter and stronger.

Buildings will be constructed faster, utilizing 3D printing technology.

They’ll become more automated and more sustainable, with nanotechnology producing advanced insulation, more energy efficient windows, and smarter appliances. Buildings will also start to take on new roles – monitoring our health, providing power, supporting an urban forest, and even maintaining and operating autonomously. The next couple of decades will likely see the electrification of all cars and trucks, along with battery powered aircraft for shorter trips. Supersonic jets and hyperloop trains will move people and goods with greater speed, their lighter and stronger materials requiring less energy for motion.

A second consequence of the Energy Efficiency Megatrend is that buildings and vehicles will evolve into sentient-appearing machines. Of course, we cannot know if machines will ever become conscious, but we will certainly start to interact with our technology more and more as if it were. We already talk to Siri and Alexa, and take directions from our cars. All of this will become much more sophisticated until we are interacting with the AI in our homes and offices - not only to answer questions and provide entertainment, but to delegate tasks and deal with deliveries. The transportation system, if we allow it, may monitor our conversations to know when and where we need a vehicle, complete with an understanding of our travel preferences. In the future, we will be living, working, and moving about inside robots.

A third consequence will be the continuing convergence of buildings, transportation, and power. The exchange of information and power between buildings, the transportation sector, and the power grid is growing, in some cases exponentially. In many important ways, the functions of these three sectors are converging into a single intelligent technological system. This is currently demonstrated in the building sector: newer buildings generate their power on-site, acting as charging facilities for the transportation

6

sector. Future construction will include buildingintegrated solar power and battery storage. Batteries in the transportation sector are being integrated into the power grid, with some cars being powered by solar carports, or by solar cells added to their frames. Buildings everywhere will become fueling stations for our transportation sector.

As convergence accelerates, the three sectors will become more robust and reliable – generating, storing, and moving energy to best meet our needs.

We foresee an accelerated trend to the decarbonization of our power grid, primarily due to solar and wind. Energy storage will eliminate the need to burn fossil fuels for electricity, expanding at all levels of our power system. We expect significant changes in the business model that has dominated the power industry almost since its beginning; as more customers become “prosumers” – both generating and consuming power – the utility industry will be impelled to accommodate and integrate distributed energy resources into the grid.

Of course, there will be some obstacles in this transition.

The aviation and maritime shipping industries will be difficult and expensive to wean off petroleum, and the movement of freight, in general, will continue to depend on fossil fuels for some time. Fossil fuels are still needed to produce the steel and concrete to build the wind turbines, solar farms, and electric vehicles. We may find sustainable ways to replace fossil fuels for the manufacturing of those technologies, but the massive deployment of renewable energy technologies we’ll need over the coming decade must be accomplished with current production capacity.

Our world is in flux. And, while the transitions to a more sustainable and efficient economy are underway, they probably won’t be as quick or cheap as we would like.

Roger Duncan and Michael E. Webber have deep experience in the worlds of policy, politics, planning, and academia. You can read more in their new book, “The Future of Buildings, Transportation and Power” (available on Amazon).

Zero-emission flight

ZeroAvia conducted the first ever electricpowered flight of a commercial-scale aircraft carried out in the UK. The test flight is a significant milestone both for the UK’s net zero and green aviation ambitions, and for ZeroAvia on the journey to demonstrating long-distance zero emission flights in large aircraft. The company successfully completed the first flight of the new version of its hydrogen fuel cell powertrain from its base at Cranfield Airport. Hydrogen-electric offers the same zero-emission potential of battery-electric, but has a much more promising energy-to-weight ratio, making it viable for commercial operations at a much larger scale and in a shorter time frame. Additionally, hydrogen-electric powertrain is projected to have lower operating costs due to the high cost of battery cycling in typical high-utilization regional aircraft. The longer-distance hydrogen-electric test flights are planned for later this summer.

Open Source

The answer to greening the grid

by Shuli Goodman, Ph. D.

The renewable energy sector shouldn’t be surprised by the effects of the COVID-19 pandemic. In fact, it was only a matter of time before we faced this kind of catastrophe; the increase in pandemics is a direct symptom of climate change.

The United States Department of Defense (DoD) said, in 2014, that climate change “will likely lead to food and water shortages, pandemic disease, disputes over refugees and resources, and destruction by natural disasters in regions across the globe.” What’s even more troubling is that the current pandemic is merely a small preview of what’s to come if we don’t act now to limit our environmental impact.

Since the DoD’s statement nearly six years ago, new research shows that, without coordinated action against climate change, the world’s uninhabitable places could increase from 1 percent to 19 percent by 2070. This necessary effort includes the energy industry, as we must do our part to update the power grid to support clean, renewable energy in order to achieve carbon neutrality by the EU’s goal of 2050.

Open source can save crucial time

The effect of climate change on our environment provides a stark reminder that we’re in a race against time to save our planet. Like COVID-19, the climate does not know borders. What we’re doing right now isn’t working; we cannot use a slow, patchwork response that creates more chaos, hardship, and civil strife than we already see today. In this moment, the energy industry must learn from its mistakes, and come together through open-source technology and shared development. This is the key to speeding up the innovation required for the grid to support renewable energy.

• The shift from proprietary solutions.

Open-source technology is non-proprietary software code that is free and available for anyone to use or modify. To leverage open source, many other industries have formed organizations to develop open-source programs that benefit their entire sector.

Instead of embracing open source, however, the U.S. energy sector has moved towards deregulation and increased competition. This movement has resulted in the reliance on proprietary solutions for grid development.

And, while we’ve seen innovative solutions from this industry model, their sluggish go-to-market speed and lack of interoperability on the grid are too slow to achieve required climate goals. We need to focus on adoption and diffusion, not just innovations.

If the energy industry comes together as an open-source community, it could lead to the accelerated innovation and adoption of renewable energy solutions our world needs. This paradigm shift to an open-source energy sector would require much pre-competitive alignment between utility providers on goals. However, we’ve seen the open-source model have success in the telecom sector, where the concept helped companies like AT&T, China Mobile, and Orange modernize their legacy technologies together. Open source also was the main driving force behind the rapid growth of the internet and its worldwide connectivity.

• Grid modernization requires increased technology diffusion.

It’s already possible to modernize the grid to support renewable energy.

Due to the variability of renewable energy, however, the grid can’t support it all without major technological advancement. To handle variability, the grid must be digitized for virtual functions, automation, software integration, and disaggregation of hardware and software.

When you pair the required innovation with the slowed go-to-market

8

SEPTEMBER•OCTOBER2020 /// www.nacleanenergy.com

speed of proprietary energy solutions and the failures of interoperability and systems integration, the combination makes technology diffusion (the process by which technological innovations are adopted by an industry) more difficult. In fact, we’ve found that the energy sector will need a 9 percent technology diffusion rate, each of the next 30 years, to reach a carbon-neutral climate.

If we keep waiting, the technology diffusion rate will only go up: to 15 percent, 20 percent, and so on, making our task even more challenging.

The energy industry cannot stand by and wait for technology to diffuse through individual efforts.

• Open source eases the burdens of technological development.

Although proprietary solutions have been a staple of the energy sector, the benefits of this industry model are little to non-existent. Proprietary isolation, which used to be a safe, easy, and cost-effective method to operate as a utility provider, is difficult to maintain in our current industry climate.

Today’s energy market demands rapid innovation and greater efficiency to reduce carbon emissions - the proprietary structure is not keeping up.

On top of its environmental impact, open source can also have a positive operational effect on individual utility providers. Energy companies that have become early participants of open source in the energy sector are already seeing beneficial outcomes. Switching to open source can have a positive impact on energy providers by: o Alleviating costs: In an open-source community, individual utility companies don’t have to shoulder development costs for renewable solutions alone. o Increasing speed to market: Collaborating with open-source partners allows energy providers to decrease the long lead time for a proprietary solution to go to market, which can help reach the EU’s goal for decarbonization by 2050 more quickly. o Reducing systems integration complexity: Open-source community members develop solutions that are compatible with each other to scale, eliminating the complicated process it usually takes to make proprietary technology interoperable on the grid.

It’s time for a technological revolution in the energy industry. Instead of wasting time as competitors, utility companies must dissolve their borders and band together on common solutions. With experts predicting more damaging environmental consequences if we make no progress towards decarbonization by 2050, what’s the point of going it alone?

Solar Training Moves Online

by Michael Barry

IN MARCH OF THIS YEAR,

in the Northeast part of the country - with spring approaching and the last patches of snow reluctantly surrendering to the season - the regional solar industry was gearing up for what promised to be a banner spring and summer. Demand for a skilled workforce was at an all-time high, and job seekers flocked to training programs to acquire the skills needed by solar and green energy employers.

Trainees anticipating increased employment, and earnings opportunities were brimming with optimism. But there was an unforeseen turn of fate ahead.

When the Coronavirus pandemic hit the New York City area, no one was yet fully aware how rapidly the virus could spread.

We all watched with alarm and sadness as the situation kept worsening. By mid-April, it became undeniably clear that this was going to be bad. Lives were lost. Industries were shuttered. Opportunities vanished.

In May, the New York Solar Energy Industries Association (NYSEIA) released a survey on the impacts of COVID-19 on the solar industry. The results were not encouraging: Solar workers were deemed non-essential by New York State; Roughly 63 percent of the state’s workforce was furloughed or laid off since March 1.

Many qualified workers looked to neighboring states like Massachusetts, New Jersey, and Pennsylvania, where some work continued, but training programs in New York ground to a halt.

Most solar training programs rely on both hands-on training and in-person team projects, where students practice in a controlled environment to prepare for real-world employment. However, as long as COVID-19 remains a danger, students cannot participate in group mock installations to learn the important skills needed by typical installers (racking, mounting, and flashing). Determined instructors quickly pivoted to leverage digital resources, including online lectures and videos.

Soon, suppliers of training programs throughout the country – beyond New York State and the northeast – began to quickly retool their hands-on training programs to suit

10

the virtual environment. Even with no certainty about when work would resume, future solar workers were eager to learn, and educators quickly adapted as a community to support their students.

Some of the earliest adapters were nonprofit organizations. In the New York City area, a network of partner organizations had already been working together in recent years to offer training to individuals who may have had past difficulties (legally, or with employment or housing), but were eager for new opportunities in the solar industry. Most of these solar training programs focus on diversity and inclusion by providing industry access for people of color and marginalized community members.

This alliance of New York City nonprofits includes Solar One, STRIVE International, WE ACT for Environmental Justice, St. Nicks Alliance, and LaGuardia Community College, along with many others. Some partner programs, like the Fortune Society’s I-CAN program, work with individuals re-entering society post-incarceration at NYC's Rikers Island Prison Complex. With reports of rising COVID-19 cases within prison populations, this program also needed to be delivered online.

Redesigning training programs from in-person to virtual formats has been a challenge, but there have already been successes. For example, even with the cancellation of in-person classes, a recent cohort of Solar One’s Green Workforce program recently completed a three-week training for installation jobs at a community solar project in Brooklyn. The partner installer guaranteed 15 new hires from this cohort. Importantly, even with virtual delivery, industry certifications continue to be provided, including North American Board of Certified Energy Practitioners (NABCEP) credentials, and the Occupational Safety and Health Administration’s OSHA 30 Construction Safety Training. These certifications help reduce barriers to careers in the solar industry.

Interest in green building and technology continues unabated, despite today’s uncertain conditions. Solar PV programs are often taught in tandem with green construction classes to ensure students leave with broad, practical, and transferrable skills. The solar installer hiring pipeline remains somewhat volatile, particularly in urban areas, so this approach helps graduates pursue multiple employment possibilities when interviewing for jobs.

On a larger scale, NABCEP offers online training and exams to a national audience. Since the crisis began in March, the organization has offered dozens of free online training classes on topics ranging from using drones for site assessment and monitoring, to solar plus storage, to mapping and site analysis software. Internationally, Solar Energy International (SEI), the world’s largest alumni network and training program for the solar industry, launched an initiative to address some less visible consequences of the pandemic. The SEI Global Solar Connection Initiative helps combat feelings of isolation and disconnection wrought by social distancing and quarantining, while fostering a sense of community around renewable energy education. When the pandemic began, 75,000 people were already enrolled in their online campus - that number has since grown steadily.

As the threat of COVID-19 persists, the landscape continues to rapidly shift.

Of course, as some regions slowly relax lockdown constraints and modify health policies, solar installation companies and training programs have adopted the now familiar safety measures such as wearing face masks, frequent temperature checks, site sanitization, social distancing, and remote technical and pre-installation site

SEPTEMBER•OCTOBER2020 /// www.nacleanenergy.com

evaluations. Certainly, some states fare better than others. When all is said and done, the national average for job loss in the solar industry is predicted to be around 38 percent. Job losses in New York and New Jersey are expected to far exceed this number, with projections closer to 60 percent. On the other hand, some states, like North Carolina, are only looking at about a 19 percent loss in workforce. Still not a pretty picture, but far better than New York.

There is an unforeseen bright spot being reported from the field: an uptick in demand for solar plus storage. Perhaps the shelter-in-place mindset triggered by the pandemic has fueled interest in energy independence technologies.

Training programs are responding in kind by including more opportunities to learn about batteries and storage topics.

Whatever the future brings, the suppliers of solar education and training are committed to providing a skilled workforce when demand inevitably returns. And certainly, solar installers are more than ready to get back to work.

Updating Our Industry’s O&M Model

by Dr. Christopher R. Jones

When you purchase a cell phone or computer for yourself, premium support is usually offered as an add-on. The manufacturer has the service conveniently priced in both monthly and yearly terms. You certainly don’t have to buy it, though it’s generally encouraged; after all, it provides protection should anything go awry and, more importantly, piece of mind to the customer. Depending on the sophistication of the device, these items can range from a couple hundred bucks to several thousand dollars. Shouldn’t a solar system that costs more (and is often harder to debug) have a similar type of support program?

Recently, a homeowner for a residential system that was installed in 2017, called the support line he was given when he first purchased the system. His issue? The CTbased consumption clamp data didn’t make sense to him. After committing an hour to properly configure his setup, the support technician discovered that the initial information he provided about clamp locations, and which circuits are clamped, was in error (two solar PV systems were actually clamped- micros and legacy string inverters- not just the legacy PV inverters as the customer believed). Once the system was debugged and proper power flow noted via live cloud monitoring, he was happy. No more calls. This customer was determined to get his problem solved.

That it might have cost him $100/year for the ability to have live support at an OEM was not a problem. The real issue? The OEM failed to charge such a fee as part of their business model. Instead, they spent a portion of their profit from the 3-yearold sale of equipment on the hour of live support.

The original equipment manufacturer is the last line of defense. The buck stops there. Without the offer of support, the customer is lost and the system’s intended features go idle. This doesn’t mean that OEM’s should bear all the responsibility.

Many installers would do these jobs, but it’s difficult to sell O&M contracts to residential customers for the simple reason that ALMOST NOBODY DOES. The industry norm is to pretend that solar lasts forever, with the standard pitch highlighting the fact that the system doesn’t have moving parts, ipso facto never has any problems.

In reality, any number of things can happen: squirrels chewed wires, lightning strikes in Florida melted auxiliary surge protectors, and wires pulled through conduit at too tight a turn radius rubbed insulation bare and shorted to ground (2 years after the installation had been operational).

Each time, the initial problem percolated down the support ticket queue with the simple subject line: ‘My solar equipment is not working.’

The monitoring provider is the front

SEPTEMBER•OCTOBER2020 /// www.nacleanenergy.com

line of inquiry. However, it’s the installer that most often bears the cost of a truck roll to implement a physical correction. In light of the fact that installers and OEMs share these different costs, it only makes sense to charge for it via contracts that require renewal to continue a vigilant watch. The installer should ask for a labor contract, and the OEM should ask for a live support contract. People have no obligation to procure these contracts - it’s their choice. But those same people can’t expect a no-cost truck roll or an hour of live phone support. These folks are welcome to read the forums and watch YouTube videos. Then, if that doesn’t work, they can opt into a contract.

Maybe the industry is reticent to tell people the truth. This reticence stems from the history of solar; it used to be difficult to sell to the extent that each sale was ‘on the edge’. The last thing salespeople needed was to tell their customers: ‘Like everything else, there can be problems after the installation is complete, so you might want to consider a maintenance contract.’ Today, PV systems pays for themselves quickly, and continue to deliver cash-money value after full ROI is realized. Why should the industry be so collectively hesitant to ask for what mature industries, and customers of those industries, take in stride?

Most IT device manufacturers promote their premium service to give peace of mind to customers who are not DIYers, and want to have access to expedient problem solving. Similarly, the auto industry understands that people will pay for hasslefree, turnkey maintenance contracts, applied to remarkably reliable vehicles that typically do not have problems.

These industries have realized that customers not only want, but require, support through the lifecycle of the products they procure. Residential solar needs to do the same. End customer support plans need to be on offer as an industry standard approach to business.

It is up to OEMs and installers to pull together on the issue, because you won’t get what you don’t ask for.

New SMART Emergency Program Regulations What Massachusetts customers should know

by Tanya M. Larrabee

THE COMMONWEALTH OF MASSACHUSETTS BEGAN

the “Solar Massachusetts Renewable Target” or “SMART Program” in 2018, in an effort to streamline and create a more accessible and cost-effective solar program for developers and electricity customers. The benefits of the program aimed to continue the Commonwealth’s status as the most energy-efficient state in the country, while increasing the stability and permanence of the solar industry in the Northeast. As of 2020, the Solar Energy Industries Association (SEIA) ranks Massachusetts 8th in the nation for installed solar, up from 12th in 2019. While Massachusetts may not be the first place most people think of when they picture solar panels, the state’s successful SMART Program has made Massachusetts a pioneer in the clean energy industry that other states are looking to follow.

On July 10, 2020, the Massachusetts Department of Energy Resources (“DOER”) completed the required SMART Program 400MW review and emergency rulemaking, and published its final regulations, 225 CMR 20.00, with the Secretary of State.

Recognizing that the COVID-19 pandemic continues to disrupt the solar industry, among its many adjustments to the regulations was an expansion of the COVID-19 extension to new SMART applications received through December 31, 2020.

Land use exceptions remained a prevalent topic in the final regulations. Projects qualifying for capacity under the original 1600MW program will remain eligible for SMART benefits, even if located on land designated as Critical Natural Landscape.

However, projects qualifying for capacity A COMPLETE PORTFOLIO OF under the expanded 1600MWs will be ineligible for the SMART Program if the project is sited in a Priority Habitat, Core Habitat, or Critical Natural Landscape.

Projects will now have to meet certain conditions to be assessed under the former land use regulations, including having applied for an Interconnection Service Agreement (ISA) 135 business days prior to April 15, 2020, or having obtained a fully-executed ISA by October 15, 2020. Projects that have obtained a sufficient interest in real estate, or other contractual right to construct the Solar Tariff Generation Unit at the location specified in the ISA as of April 15, 2020, For More Information: may also remain eligible under the info@eciusa.com previous 1600MW land use rules.

The final regulations recognized the benefits of solar tracking systems. They will now allow for single axis trackers to be eligible for the Tracker Adder – this is especially important given the stricter land use provisions, as developers may now need to find innovative ways to electricalconsultantsinc.com efficiently design and utilize smaller

land parcels. The regulations also made behind-the-meter (BTM) systems eligible for the sale of Alternative On-Bill Credits.

The DOER made the following additional modifications to the Statement of Qualification Reservation Period Guideline: • Clarifying that projects qualified as Community Shared Solar, that do not submit a claim with the CSS Adder, will have their base compensation rate decreased to the value in the lowest available Capacity Block, but will not be at risk of losing their Statement of Qualification outright; • Establishing a process by which DOER will queue project applications if there is a rush of applications submitted following the issuance of interconnection agreements by a Distribution Company upon the completion of an Affected System Operator (ASO) study; • Eliminating the requirement that projects obtaining an indefinite extension pending the authorization to interconnect must submit a claim within 10 business days of receiving the authorization to interconnect; • Granting eligible Public Entity Off-taker Adder Solar Tariff Generation Units an initial Reservation Period of 18 months.

The publication of these new regulations is just one piece of the puzzle for maintaining the SMART Program. Several other guidelines related to this program are subject to revision, and expected in the coming weeks. Additionally, all regulatory changes that effect the tariff will now need to be implemented into each Electric Distribution Companies’ tariffs, and undergo the administrative review of the Department of Public Utilities.

As COVID-19 continues to impact the industry, DOER may make additional adjustments to project timelines and deadlines. Additionally, as the SMART Program’s tariffs are filed at the Department of Public Utilities and focus shifts to a tariff proceeding, there may be additional changes that occur.

It is extremely important to continue to keep tabs on the DOER and SMART Program in order to stay up to date with their latest procedures and timelines. Always remember to consult with an attorney if the language of the new updates is unclear, or if you find that your Project is in a unique situation, to ensure you are receiving the greatest benefits of the new regulatory changes.

Remote Inspecting

A social distancing solution

by Christopher Beauchamp

IT IS A COMPLEX AND CHALLENGING TIME

we presently find ourselves in. Consequently, there are several factors currently affecting the installation of solar in the United States. Social distancing has slowed down the permitting process for building departments across the US, which hinders all stages of construction. But delayed inspections do not have to hold up progress - remote inspecting solutions are already in place. For example, one remote solar inspecting app, available on both iPhone and Android platforms, has been in service for many years. While the success of the app proves that remote inspecting works, many building departments are slow to get onboard and hesitant to adopt new technology. Historically, a major crisis or event has been the catalyst for worldwide change; COVID-19 has proven to be no exception. Some municipalities now accept remote/virtual inspections. As the benefits of these inspections become more evident, more local utilities will likely follow. Many companies are only now realizing that employees working remotely from home is a viable option to a central office space. Building departments should also recognize the value of working remotely, and the different ways it can be done. Prior to the current pandemic, many city officials revealed that their inspectors were overwhelmed and forced to regularly put in overtime hours. The time and expense differences between in-person and remote inspecting alone should have been its own catalyst for change.

I recently had a new bathtub installed in my house. Headway on, the installation was stopped while waiting for the city inspector to arrive - he ended up coming to my house three separate times. Rather than making the inspector travel back and forth between my house and his office, the installer could have photographed the items needing inspection and the inspector could have completed the review everything remotely, on his computer, without ever having to leave the office.

This could have reduced (or even eliminated) the number of trips, and the job could have been completed several days earlier. Advancements in technology have made so many things in our lives easier, changing the way we handle daily tasks and navigate the world. Building departments need to take advantage of new technology to help streamline work flow and speed up the permitting process.

Basic Remote Inspecting Process Using App

1. A member of the installation crew is directed through the app, step-by-step, to answer questions and take specific photos required to make a proper assessment of the installation. To guarantee that the inspector receives all the necessary information, some apps will not submit if any details are missing.

Note that all of the data is geo-tagged and time-stamped to provide a record of the time and location of all information gathered.

High power, high performance panel

2. The inspector reviews the information from a computer, without having to physically visit the site.

3. The building department can keep this data on file, along with photos, as proof of their findings.

Installer Benefits

1. The app eliminates stops in production, since there’s no need to wait for an inspector to arrive onsite.

2. Corrections required by the inspector can be fixed, photographed, and sent back to the inspector in a timely manner.

One small failure should no longer delay sites completion.

3. All documentation of the site can be used as proof of quality workmanship for potential new clients.

4. If issues arise at the site after completion, the data covering the entire installation (from the main service panel to the array) can be reviewed to determine the cause of the problem, which can reduce or eliminate additional truck rolls.

5. Ensure crews are installing solar per your instructions. Many clients had no idea their crews were doing sub-standard work that did not meet NEC requirements. Pointing out these failures as they occurred meant that changes could be effected immediately, helping several installation companies with quality issues.

6. Confirm that contractors are doing the work correctly and upholding your quality standards; a couple of bad installations can hurt your company’s reputation, which could limit the amount of new jobs coming in.

Electronic filing of permitting paperwork is gaining acceptance in many areas. The days of physical trips to city hall, lugging stacks of paperwork, are slowly fading away.

Many cities are expanding their websites to accommodate the new processes. In the near future, wet signatures and raised stamps or seals for document execution could be replaced with e-signature services.

The sooner we institute electronic filing and remote inspecting, the quicker we can help ease the economics effects of the current pandemic, and make a smooth transition to a more efficient process.

Boosting Value by Integrating OEM Agnostic Data

by Mark Brown

Declining levelized costs of energy and rising capacity factors for renewable energy assets continue to fuel industry growth globally. With intermittent resources increasingly competitive with more traditional, “dispatchable” energy sources, asset acquisitions are rampant. This has left new owners with a dizzying mix of OEM assets and technology.

In a system with a combination of technologies, not only is a lack of standardization expensive to maintain, it is difficult to integrate into enterprise operations. Clearly, a standard automation strategy that consists of both hardware and software will help extend the life of existing technology, while reducing the total cost of ownership.

Many existing automation platforms lack the advanced capabilities and interfaces to support evolving business models. As owners continue to search for ways to increase the value of their assets, robust data acquisition, analysis, and control capabilities will be critical to realizing value beyond kilowatt-hours.

Whether performed internally or by a third party, leveraging a single interface to monitor all remote assets helps improve asset performance and reliability. Renewable assets are, by their very nature, remote. Unlike what you might find in a traditional fossil fuel power plant, solar and wind power generation facilities are not teeming with operations and maintenance personnel.

SEPTEMBER•OCTOBER2020 /// www.nacleanenergy.com

Because of this, the remote operations center (ROC) is now a necessity in an owner’s overall strategy. The ROC exemplifies the challenges of a mixed portfolio. Whether performed internally or by a third party, leveraging a single interface to monitor all remote assets helps improve asset performance and reliability.

With the responsibility to operate diverse assets and dispatch personnel to address issues at each facility, a platform that provides automation, asset management, and computerized maintenance management will maximize operational value while driving down costs.

As owners expand their portfolios and their business models change, they should not be constrained by asset type, existing OEM automation, integration capability, or the lack of ability to scale functionality.

Developing a strategy that employs a standardized automation and integration platform will address these issues, and enable more effective enterprise-level asset performance management (APM) and workflow functions.

It is essential to manage data correctly and understand its inherent value. High quality data not only improves decisionmaking, compliance and productivity, it helps maximize asset value. Poor data could result in lack of confidence in new initiatives, and even reputational damage to an organization.

Understanding the value of data is a positive step, but how do companies manage it correctly?

First, they must understand the source of the data and the path it travels to end up on PC displays, smart phones, and tablets. In the case of the renewable energy industry, data originates from countless sensors, data loggers, PLCs, SCADA systems, and other sources.

A component crucial to effective data governance relates to the workflow for managing known bad data. Operators must maintain a definitive process for validating data, substituting corrected values for known bad values, and maintaining an “audit trail” that records all substitutions.

Fortunately, the industry can look to non-OEM automation and data consolidation platforms that integrate seamlessly with any asset, and natively provide advanced capabilities beyond the original scope. The ability to normalize varying technologies with an overlay solution can increase data availability and reliability - without the need to replace existing hardware or software.

Data created by renewable assets can be just as valuable as the kilowatt-hours they produce. Companies should consider investing in a data overlay solution that will normalize the various technologies in their systems, while increasing data availability and reliability. Because asset data is used more often in downstream enterprise IT systems (such as Energy Management Systems and Asset Performance Management solutions), tight integration with automation infrastructure will allow operators to realize the value of that data.

As an example, an owner of one of the largest fleets in North America sought to insulate operations from high operation and maintenance provider turnover at their commercial- and utility-scale solar PV assets. The portfolio involves several operational and business activities taking place simultaneously. Therefore, the owner needed a platform that empowered people to take accountability by providing them with the information they need, when they need it.

The primary objective was deployment of an OEM supplier-agnostic system to collect process data from the entire portfolio of widely distributed assets. The owner’s procurement team selected an overlay solution that maintains data using an industry-leading historian in a hosted system. It provides a complete financial analysis, actual power generation vs. potential, and asset optimization.

A portal presents this information to management, operators, service technicians, and relevant partners via standard dashboards and reports.

Readily available information includes availability, net production, gross production, and weather adjusted production. The portal also provides capacity factor based on production rates and installed capacity; performance ratio based on production, installed capacity and POA irradiance; and efficiency based on AC and DC generated power. Rollout analyses can drill down to any level including inverters, arrays, sites, funds, and business units. Analytics provide asset alerts like unproductive states or low performance.

The overlay solution is operating at over 400 assets, and now monitors 25 percent of commercial-scale solar PV generation in the United States. It has been elevated to the system of record, and is the only means for the owner to monitor specific assets. Regardless of the number of partners, the system uses

a single data pipeline through the firewall. The solution has significantly reduced cyber security vulnerabilities. Additionally, low operating costs have maximized the short-term return-on-investment, while expandability provides a standardized solution for the future.

This seemingly simple capability is valuable because it allows assets to participate in additional market opportunities such as ancillary services. As power purchase agreement (PPA) prices continue to fall, it will be more important than ever for owners to have access to these additional market opportunities—many of which provide better profit margins than just selling kilowatt-hours.

Operational challenges to roofing and solar during pandemic

by Rob Newman

THE ROOFING AND SOLAR SECTORS ARE FAMILIAR WITH

problem solving. Whether it's tackling contracted surveying or conducting on-site inspections, our industry knows how to observe and execute on the everyday challenges that are part of the job. Our industry is also familiar with being prepared. That's why crews put so much effort into design planning, inspections, and bidding to win new projects. All of this said, these challenges aren't going away because of the current global pandemic. Instead, they are being compounded, requiring more creativity in tackling them than ever before.

In addition to upending the way many industries are defining "work," COVID-19 has brought three macro challenges to the forefront of roofing and solar:

Challenge 1: Ensuring Safety

Safety is a constant element of our industry.

The inherent physical nature of the work dictates that safety be considered at all times.

Precautions should advance and adapt with the times, and a global pandemic is no exception. COVID-19 is pushing us to reconsider what safety means on the job site. On top of the usual safety concerns like dangerous equipment or environmental hazards (i.e., heights), we now need to be constantly aware of how many people are on site, and how this could increase the risk of transferring a highly contagious virus. We need to consider how to reduce the amount of personnel absolutely necessary on site as a way to mitigate the amount of exposure to an entire crew, while still being able to work efficiently.

Challenge 2: Mitigating Physical Distance

A safe work environment with a reduced number of workers on site brings up another challenge - how to make up for lack of personnel, and maintain a high level of quality at a distance. Traditionally, prospecting and surveying on site has been an almost inseparable element of working in roofing, construction, solar, and other kinds of government prospecting. Having a detailed understanding of a

project is not just a nice-to-have, but an absolute necessity for operations. One miscalculation can snowball into a detrimental series of setbacks. With the need to cut the number of people on site, construction crews and roofers need to get creative with how they can achieve the same level of accuracy and detail on a project using a leaner workforce and increased distance from the work site itself.

Challenge 3: Maintaining Speed

At the best of times, speed is a constant factor in construction projects. Schedules need to be kept to, deadlines are always looming, and one delay can cause an avalanche of setbacks. Most projects have come to a complete halt, which

has already put countless teams under incredible pressure. Worse yet, it doesn't seem like it will be possible for crews to get back to full operational strength for a while - which means speed is significantly hindered. In an industry that is always racing against the clock, we need to think about new and innovative solutions to mitigate the strains on productivity that COVID-19 has put on our industry.

decisions easier, and reducing unnecessary foot traffic. The tech also accelerates surveying speed, meaning that, even during the pandemic, every opportunity can be taken to speed up the more time-consuming part of on-site surveying.

Every industry is feeling the pressure to adapt to new ways of working. As we continue through this pandemic, we all need to be mindful of how to take care of our crew members while still delivering on deadlines. By being cognizant of the new challenges and staying open minded to new technological solutions, we not only better equip ourselves for the present challenge, but set ourselves up for greater success and innovation moving forward.

RUGGED EXCEPTIONAL DEPENDABLE We already have the solution

Though the strains of COVID-19 can feel like they're continually mounting, the good news is that each of these challenges can be met and tackled with existing technology. One of the most powerful emerging technologies in our industry is on-demand aerial imaging. This cuttingedge technology allows roofing and solar businesses to handle the common challenges of the job. Given the current circumstances, it has the potential to become a game-changing tool.

Aerial imaging technology solves the challenge of safety and distance by reducing the need for on-site personnel.

By using the technology to do more preplanning on a project, crews can have a better picture of how many people are absolutely necessary on site, and plan accordingly. Aerial imaging tech is able to give planners a highly detailed image of the project - scaling proportionally down to the pixel - making budgeting and staffing

Solar and Batteries Graduate from Intermittent Renewable Class

by Abbot Moffat and Jesse Salveson

LOW-COST VARIABLE RENEWABLE ENERGY (VRE)

is altering the power delivery landscape – for the greener and better. The most notable alternative energy source illuminating new possibilities is the pairing of photovoltaics (PV) and batteries, particularly lithium-ion. Together, these systems have emerged as a reliable solution to increase power-grid flexibility. According to a PV report from the International Energy Agency (IEA), “Solar PV is well on track to reach the Sustainable Development Scenario (SDS) level by 2030, which will require electricity generation from solar PV to increase 15 percent annually, from 720 TWh in 2019, to almost 3 300 TWh in 2030.” Looking at the United States, the same PV report said that 13.2 GW of solar PV should have come online in 2019.

Batteries have also emerged as a viable in-front of the meter (FTM) solution because they are uniquely capable of absorbing, holding, and re-injecting electricity back into the grid. Unlike legacy battery storage systems, this new generation of batteries brings scalable flexibility, allowing them to be deployed across a range of supply needs. Most of the market is gravitating towards lithium-ion batteries; when paired with PV, these

SOLAR SPECIFIC UL 891

SWITCHBOARDS OFFER ADVANTAGES!

C & I (Commercial and Industrial) to utility-scale storage systems can store anywhere from a few megawatt-hours (MWh) to hundreds of MWh. For system operators, this storage solution offers grid ramp-rate control and frequency response services while enabling VRE penetration by storing excess power.

As coal’s future goes up in smoke, look to the golden state

The Golden State is hedging its bets on the PV and battery combination to the extent that the major state utility signed seven contracts for a total of 770 megawatts of lithium-ion battery-based energy storage, to enhance the regional grid’s reliability and replace four large coastal once-through cooling plants. In addition to these projects, the California Public Utilities Commission (CPUC) is putting pressure on power providers and community choice aggregators to procure 3.3 GW of storage and PV-plus-storage systems to solve grid congestion, and to compensate for gas and coal plant retirements.

Due to PV and batteries’ proven reliability, demand to fire-up California’s 52 peaker plants will steadily decrease.

COVID-19’s impact on overall energy consumption is another economic prognosticator reading coal’s tea leaves. According to the IEA, the pandemic lockdown resulted in a 10 percent to 35 percent power decrease across all impacted areas, which, in turn, increased the overall share of VRE used. This decrease in energy use, plus the additional VRE capacity coming online, will hasten fuel coal’s departure rate from our power-dependency needs. Due to the high cost of coal plant operations, many utilities are already cutting back on coal dependency in favor of renewables.

“Bee” careful! Solar farms are ecosystem disruptors, too

Lessons learned from fossil fuel extractions are now applied to biodiversity areas targeted for solar farms. The foresight to protect existing habitats is especially needed since the United States Department of Energy’s (DOE’s) Sunshot Vision Study set the goal for 14 percent (329 GW) of the nation’s electricity is to come from solar generation by 2030. Given this aggressive target, and the fact that ground-mounted solar typically requires about 5-8 acres of land per megawatt, the potential to impact nesting habits and prompt significant changes to vegetation can contribute to declining pollinator populations, i.e. bees. Planting pollinators beneath modules can foster native insect populations as well as actively maintain commercial bee hives, supporting a wide range of private and public needs.

Pollinators are extremely important— especially to our nation’s food supply.

Projects that carefully consider panel height, shading, and spatial arrangements prior to deployment, will decrease any negative environmental impacts. To keep vegetation from overtaking the PV and decreasing effectiveness, “solar grazing” practices can be deployed along with environmentally responsible planting practices. Solar grazing is a technique using animals to “mow” the vegetation around the array so it does not shade the panels. The American Solar Grazing Association was founded as a New York not-for-profit to inform and service solar grazing providers.

Technology and eco-passion exhibited by a new generation of business-minded individuals are quickly writing an epitaph for the fossil fuel barons of past decades. It took a global pandemic for utilities to truly realize that they don’t need to fire-up coal peaker plants to augment power, when VREs can do the job even more effectively.

Backed by new government goalsetting targets, solar generated power is poised to become a common, local option that communities and business users can easily embrace. When utilities need additional electricity to support peak usage, during the increasingly common climate events such as heat waves or other extreme weather conditions, they can now tap into the power stored in batteries from short distances away to fill the temporary gap.

Unlike the environmental scars left by mining, drilling, and oil spills, solar has the potential to blend into ecosystems with very little impact. PV environmental protection actions will usher in a new era of “solar herders” that will maintain North American Clean Energy

Raising Capital While Cutting Loss

by Robert W Benedict III

Large developers who create lucrative projects are very attractive for long term investors. Development is a side of the industry that runs primarily local, which is why big corporations require working with local companies to build their portfolios. The organizational structure of developer businesses favors a smaller workforce to maximize revenue. Developers want to take as little risk as possible by using OPM (Other People’s Money), often outsourcing parts of the project, creating an opportunity for project-level capital investment.

Because flat roofs are never flat

24

SEPTEMBER•OCTOBER2020 /// www.nacleanenergy.com

As projects move toward NTP (Notice to Proceed), the money starts flowing. Instead of using an additional development company as intermediary, the originator performs due diligence to find the right long-term owner. In a normal scenario, the green field developer creates the opportunity, then sells it to the more significant developer. That developer continues the process and takes his cut of the deal. Ultimately, the project is sold to an IPP (Independent Power Producer) or utility. If the original developer can skip that middle step, they position themselves for greater profit when the deal is complete.

Profitability, value creation, and liquidity are necessary for long-term excellence.

Even a dynamic professional culture needs a strategy. Surprisingly, simply having an experienced group of qualified professionals that focus on the details necessary to execute the project to completion is not a guaranty that the final product will be successful. This is also true with the investment capital to sustain it - some investors are just not worth the money.

The path companies follow to capitalize and increase their assets also dictates the actions they need to take to accomplish their goals. Developers frequently choose the road that offers the most significant possible upside, without thinking about how capital structure creates risk in achieving that upside. Regardless of circumstance, when investment contracts are agreed, the receiver will have to give something up. It is important to feel comfortable with all the terms established, and understand how this agreement will impact not only the project, but you personally. Development is an incredibly cash-intensive business; when you’re short on cash, it ultimately takes away opportunities. You must think about capitalization at all times.

Refusing outside capital leaves you with one choice: self-financing. If the developer had enough funds to pay for the project, he’d have all the decision power. That, however, requires a lot of conviction (as well as a vast amount of resources). Developers trying to raise cash at the corporate level need to have a clear plan, a market that can be utilized, and the resolve to stay within that market area. While selling to larger developers can be a rewarding situation, it tends to be fraught with challenges because everybody is competing for capital. Inevitably, this creates a project hierarchy, with money flowing to the most lucrative opportunities.

Raising project-level development capital is challenging and costly, but it allows for some of the benefits of self-financing, giving you more control over your destiny.

The world is building more solar-power plants because they’re getting cheaper.

Since 2009, the total installed costs of solar have decreased by 70 percent around the world. New power purchase agreements (PPA’s) frequently fall below $100 per megawatt-hour, with some falling below thirty dollars ($30). That price puts solar at or below the cost of a new natural-gas plant.

Regulatory measures like the Investment Tax Credit (ITC), further support the economics of solar. In many instances, solar is often “the lowest cost energy”, notably less costly than the next cheapest alternative. A number of leading multinationals are signing solar deals not only to gain green credentials, but also to lower their energy costs and diversify their power source.

When adding banking interest to re-rate solar, the cost of these projects drop even more, becoming a better investment for the greenfield developer. Consequently, every other company involved in the process will also receive worthwhile ROI’s. Ideally, the project finds a home where everyone involved is able to share in the economics.

Given these trends, it’s estimated that 2,000 to 3,000 GW of solar capacity - or almost half of total electric-power capacity in the world today - will be done by 2025. While solar alone can’t fully meet the need for electricity (because the sun doesn’t always shine), and we need to concentrate on balancing energy to keep the grid healthy, solar’s continued growth will nonetheless transform energy markets around the world.

New roof hooks save material and installation time

The Schletter Group has launched two new roof hooks for pitched roof installation. For low loads, the company has developed the new EcoA roof hook, made from aluminum. It allows fast, flexible mounting using hooks and is fixed in place with just one Torx plate head screw. The hook is height-adjustable and can thus be used for different roof battens. It can also be combined with all standard Schletter profiles. The new HSL roof hook series is for high wind and snow loads. The one-piece welded roof hooks with a rail thickness of 6 or 8mm are made from high-strength steel. The degree of strength meets all the requirements as regards mechanical strength, stability, structural integrity, and durability. A new zinc flake coating makes the roof hook particularly resistant to corrosion. The newly developed spacer plate, which is suitable for all Schletter roof hooks in the Rapid and Eco ranges, allows variable height adjustment in 2.5mm steps.

Plug-in easy-test terminal blocks

Dinkle International announces the availability of its DPT DIN rail disconnect terminal blocks to provide efficient, safe disconnect and testing of current transformer (CT) and voltage transformer (VT) circuits.

The DPTD6 model block provides direct-testing technology, enabling a user to test the circuit current without undoing any wired connections. To perform direct-test for a single or three-phase circuit, the user switches a lever on the terminal block to disconnect a de-energized circuit. The user then places a currentmeasuring device across the block at its test points using either 4mm test probes or securely fastened 2.3mm test plugs. The DPTL6 model version is similar to the DPTD6 but without a disconnect lever for testing. Both blocks are UL rated up to 30A at 600Vac. The blocks are DIN rail mountable and measure 8mm in width by 103.2mm in height by 50-57.5mm in depth (depending on DIN rail depth), allowing for easy installation and space saving. These push-in style blocks accommodate wire sizes from AWG20 to AWG8, and also feature plug-in slots for bridges (jumpers), providing reliable continuity between any combination of blocks on the same DIN rail. They are completely touch-safe—back of hand and finger protection—and operate at temperatures from -40°F to 248°F (-40°C to 120°C).

Power and flexibility for DC power projects

Alencon Systems, LLC’s BOSS BOX and SPOT BOX are scalable, centralized units of DC:DC power conversion built on Alencon’s galvanically isolated, bi-directional and uni-directional platforms.

The BOSS BOX is a bi-directional DC:DC conversion platform made up of a configurable number of Alencon’s 80KW Bidirectional Optimizer for Storage Systems (BOSS) modules. Each BOSS BOX can be configured to scale power conversion from about 250KW to 2.5MW depending on project requirements. The BOSS BOX allows varying levels of control from entire cabinets to individual DC:DC converters. This level of granular control can be particularly helpful in controlling batteries to the rack level while integrating them with large solar projects using the DC-coupled technique. The SPOT BOX is a uni-directional DC:DC conversion platform made up of configurable number of Alencon’s 80KW string power optimizer and transmitter (SPOT) modules. The SPOT BOX is a cost effective solution for boosting voltage from aged 600V PV arrays to new 1000V or 1500V transformerless inverters.

Other applications can also include the uni-directional charging of electrical vehicles from a centralized DC-bus or battery. Both the BOSS BOX and SPOT BOX come pre-wired with appropriately sized copper busses to assure quick field installation. All individual BOSS or SPOT modules are installed on standard 19" racks with sliding trays and optional input/output fused disconnects for quick installation and field service. The BOX form factors also offer a flexible level of control through the features of the Alencon Communications Environment, including easy integration into third party energy management (EMS), supervisory control and data acquisition (SCADA), and other control systems via an intuitive, standardized Modbus TCP-IP interface.

Large-scale hydrogen plants

Nel Hydrogen manufacturers Alkaline and Proton Exchange Membrane (PEM) water electrolysers, which, when connected to a source of renewable energy, produce from 0.27 Nm3 to 5,000 Nm3 of Green Hydrogen per hour. Units can be grouped together into electrolyser plants for even larger production rates. Electrolysers are used to store excess energy (electricity) from renewable resources in the H2 bond. The hydrogen can then be sold to industry (converting curtailed power to cash), or burned in a turbine or run through a fuel cell to put the stored energy onto the grid during periods of low generation or peak demand. Due to their fast response times the PEM electrolysers are also used by renewable energy plants to balance the power put onto the grid.

Meet PowerGrip Universal 7 One of the strongest solar anchors in the industry!

www.q-cells.us

All solar mounts work well on calm sunny days when there’s no wind, rain or snow blowing around. But for commercial solar arrays, you need a solar anchor that’s designed to handle the worst that Mother Nature can dish out!

Pre-assembled mounting components

The new PowerGrip Universal 7 from OMG Roofing Products is designed to handle nature’s worst!

The S-5-PVKIT 2.0 pre-assembled components provide a simple, secure, and economical method for attaching solar panels to any metal roof type and enable installers to direct-attach PV modules to a metal roof’s seams or ribs. Cut labor costs by 30-50%, eliminate the assembly and installation required by traditional rail methods, and lower the number of total components from 10 to three. The system delivers up to 30% hard goods savings and an 85% reduction in weight (added collateral load) of the mounting materials. While reducing the weight of railed mounting, loads are also 25% more uniformly distributed into the structure.

Saves freight, logistics, lifting equipment, and labor costs associated with rail.

Certified electrical bonding (UL2703).

Tested and published holding strength.

Site-specific engineering to resist the forces of nature.

PVKIT is compatible with all S-5! clamps and brackets. S-5! products are warranted for the life of the solar and the roof.

It provides up to 2,000 lbf of shear strength, 1,500 lbf of tensile strength as well as the ability to withstand compressive loads of up to 2200 lbf*.

In addition, it’s compatible with every type of commercial roofing system, easy-to-install, and helps reduce ballast while providing a secure watertight connection directly to the roof deck or structural members.

So next time you’re looking for superior performance in a commercial solar anchor, look beyond those sunny day mounts, and consider the PowerGrip Universal 7 instead. When the next storms blow in, you’ll be glad you did!

For the latest PowerGrip anchor information and samples, please contact Kevin Kervick at kkervick@omginc.com or call 800.633.3800 x1217.

Energy efficient, low voltage floor heating

Electro Plastics is the manufacturer of STEP Warmfloor, a low-voltage heater based on self-regulating PTC Nano Polycarbon technology. Because the heating element is self-regulating and acts as a floor sensor, it cannot overheat; as the material warms up, it consumes less electricity. The system is very energy efficient, operates on extra-low voltage, AC or DC, and can be connected directly to renewable energy, like solar or wind. Maintaining an even low temperature is more efficient than an on/ off system and requires less solar panels, which makes this a solution for Net Zero Energy buildings. The installation is simple, and the thin and flat heaters can go under most flooring. Used for primary heating and floor warming; it is also available for snowmelt and roof deicing. All products are manufactured in USA with sustainable, non-hazardous and recyclable materials.

Keeping You in the Dark An introduction to ADLS

by Jesse Lewis and Helen Lewis

Aircraft Detection Lighting Systems (ADLS) originated out of the “dark sky” initiative started in the 1950s by astronomers, who were concerned that nocturnal skyglow was obscuring stars. In 1988, the International Dark-Sky Association (IDA) was formed to reduce inappropriate or excessive use of artificial light. Wind farms, high voltage transmission lines, and communication towers in remote areas were particularly targeted. Most of us refer to this phenomenon as “light pollution”, affecting not only our ability to clearly see stars in the night sky, but also the natural behavior of animals - especially migrating birds.

In 2011, the FAA Obstruction Evaluation Services started research into radaractivated obstruction lighting technologies. They developed standards that resulted in AC70/7460-1L as Chapter 14: “Aircraft Detection Lighting Systems”. The FAA Technical Note states that, “Due to the number of existing telecommunication towers and wind turbines, combined with expected future construction, the number of obstructions that have these required lighting fixtures has greatly increased. The light generated by the increased number of fixtures has created a light pollution nuisance to residents living near these obstructions. Using an ADLS could have a positive impact on this problem by limiting the amount of time light fixtures are active while still providing a sufficient level of safety for pilots operating at night in the vicinity of these obstructions.”

ADLS radar monitors the airspace around the windfarm for aircraft. When aircraft cross a pre-set perimeter, the system signals the wind farm network to turn the lights ON. When the aircraft exits the control perimeter, the system issues a “lights OFF” signal. The objective is to have the lights OFF as much as possible. Many rural areas have limited aviation at night, and so enjoy lights off the majority of the time.

The FAA has designated that the radar should be able to detect the aircraft a minimum of 3 NM (5.5 km) – horizontally - away from the obstruction or perimeter of a group of obstructions. It should also provide vertical detection coverage from the ground up to 1,000 feet (304 m) above the highest part of the obstruction or group of obstructions, for all areas within the 3 NM (5.5km) zone. It must be noted that not all wind farms are on flat plains. Some are in mountainous areas, which is why the “highest part” of the obstruction(s) is crucial. The 1000-foot limit eliminates the lights coming on and off due to commercial air traffic; depending on the location, these aircraft will be flying far above the obstruction. The FAA does, however, reserve the right to prohibit the use of ADLS, modify or adjust the lighting plan, and have input on the sensor's location. This typically applies in areas close to airports, low level flying routes, near DoD facilities, and where frequent low-level flights occur.

Safety is the most important aspect of an ADLS. The operational default is lights ON, until every criterion is met and approved by the system to turn the lights OFF. The ADLS system has a heartbeat; if there is a loss of communication by any device, the lights will default to ON until all system components are back online. To ensure the radar system is always optimized, the system is monitored remotely 24/7, 365 days a year.

The radar is generally placed on the ground, but can be placed on top of a transmission tower - wherever it can get a clear line of sight (radar is not X-ray, and can be blocked by solid objects like buildings and mountains). Radar sends out a pulse of energy and measures the time it takes to reflect from a target and return to the radar antenna. The time it takes the pulse to reach the target provides the range. Distance to the target is one-half the time of the round trip. Detailed GIS studies and modeling are

54

SEPTEMBER•OCTOBER2020 /// www.nacleanenergy.com

done of the area to create viewshed maps, which give the ADLS provider and the customer the best information on where to site the radar.

Compared to placing a radar on a high tower, installation costs are lower for ground-based systems. Ground-based skid systems also offer lower cost O&M compared to placing the system on a tall tower, which requires a certified climber. In some cases, a ground-based system isn’t feasible due to insufficient radar coverage, and a tower system is unavoidable. Once the location for the radar has been selected, the system is placed and anchored to a concrete pad.

Power and fiber are connected to the cabinet/radar unit (for remotely located equipment). The commissioning phase involves 7-14 days of radar operation to ensure the system is optimized. The main issues with optimizing radars are the removal of false positives in the radar signal (birds, vehicles, clutter, etc.).

After commissioning, flight tests are done to confirm the system is functioning optimally and in compliance with FAA requirements. When commissioning and testing are complete, the ADLS can go live. Once operational, the only onsite work will be a yearly inspection of all components, and a site visit by a technician.

Almost all issues can be resolved via remote connection; on-site and remote staff can be trained to monitor the system. The ADLS SQL data system compiles and stores all data while the system is operating. The FAA requires a minimum of 15 days of data storage. Daily reports are sent to the client and to Government regulating bodies, as required.

ADLS monitoring can help wind farm operators meet all necessary requirements regarding light pollution. From siting through to operation, it’s a comprehensive approach to ensuring safe delivery of clean energy (for both people and animals).

Trailblazing Island Utility Uses AI for Financial and Environmental Gains

by Devashish Paul

DESPITE THE SUDDEN DROP IN FOSSIL FUEL PRICES

due to low demand during the global pandemic, the trend to rely on more renewable energy sources continues. The reduction in emissions from industry and commuters in urban settings has resulted in clearer skies and fresher air over typically smogblanketed metropolises around the world. This transformation has given business and government leaders a taste for making these healthier conditions permanent.

But renewable energy proponents everywhere are challenged by an inherent characteristic in most of the generation sources – variability. Solar panels depend on the sun, and wind turbines on the wind. Wind is notoriously mercurial; wind patterns shift dramatically over the course of seasons, months, days, and even minutes. Too much wind is also a problem, since turbines may need to be shut down to avoid damage by wind velocities higher than they are certified to handle. Maximizing wind usage in smart grids is especially difficult.

Until the intermittence of renewables can be managed effectively, the pace of decarbonization will be throttled. One trailblazing municipal utility is throwing artificial intelligence (AI) at the problem.

The city of Summerside, Canada is located on Prince Edward Island (PEI) in eastern Canada. The island has significant wind penetration, with approximately 204MW capacity. The municipal utility, Summerside Electric, operates 12MW of its own, along with independent power producer (IPP) contracts, which brings this capacity to 21MW. Despite the often-plentiful wind, Summerside Electric still must import a large part of its energy from the neighboring province of New Brunswick via undersea cable.

That supply is a combination of renewables and fossil fuels, with about 40 percent from coal/gas/oil over the year.

Accurately scheduling the hourly grid import purchase from New Brunswick is an ongoing challenge. If Summerside commits to more energy than it ends up needing, the utility takes a financial hit putting energy back on the grid at less favorable pricing.

If it underbuys, then it needs to purchase at the hourly marginal market pricing on the shortfall, which can be high relative to the contract pricing.

When the utility uses local renewables, the cost is significantly lower (both the operating price tag and emissions). The imported energy, on the other hand, generates hard costs, as well as emissions rated at 280g CO2e/kWh. Producing more wind energy than needed is also not ideal, since selling at the market clearing price is typically lower than the purchase price - and can be rock bottom if everyone is selling power back at once. As an island community attached to mainland North America by an undersea cable connection at a single point, the city is vulnerable to outages.

In their commitment to growing a greener energy-producing community, the municipal leadership was open to new ideas and technologies. The solution they implemented is based on a distributed, data-driven, AI-enabled platform. The edge AI platform ingests data from IoT devices deployed in the field or at the grid edge, along with external data sources such as global weather feeds and simulations. It uses that data to predict the amount of energy the weather-dependent renewable facilities will produce, as well as how much energy the city will need.

AI models are trained on data collected from around the world. Imagine if everyone driving a car could learn from the experiences of all drivers worldwide, in every kind of road and weather condition, connected to one system.

56

SEPTEMBER•OCTOBER2020 /// www.nacleanenergy.com

This is how the distributed architecture benefits the city. In this case, the module at the center manages and coordinates the edge modules, carries out the intensive computing of input data, continuously adapts the AI models, and dispatches back to the edges. Both the edge and center modules are hosted in the cloud, and offered through a softwareas-a-service (SaaS) model.

This AI system is helping Summerside Electric refine operational efficiencies and offset carbon use. The predictive technology is yielding up to 50 percent improvement in energy scheduling accuracy over the utility system baseline. This means that grid imports are better matched to actual demand. Thanks to improved scheduling accuracy, the utility is enjoying an annual cost savings in the mid six figures, which is projected to grow as it increases its use of renewables. It is achieving an annualized average CO2e emission reduction of 4,100 tons - equivalent to driving a passenger vehicle more than 10,000,000 miles, or the amount of carbon sequestered by planting almost 68,000 tree seedlings after 10 years of growth.1 An AI-enabled approach improves on conventional, rules-based programing by executing decisions faster and solving for multiple objectives simultaneously. The utility’s initial deployment has tuned the platform to maximize the use of wind energy sources. Future plans at Summerside Electric include a large solar PV and battery storage facility that will be integrated into the same energy management system.

The AI platform can also predict and optimize around battery storage.

In Summerside Electric’s case, it has residential and commercial thermal energy storage (furnaces and water heaters) that store energy. In the future, the system could optimize for any combination of battery or thermal storage cycling (optimal times to charge and discharge), energy market pricing, peak shaving and more. Down the road the utility could manage other behind-the-meter smart devices such as residential electric car chargers, air conditioners, even the household dishwasher – wherever the data is. The resulting grid resilience will mean that Summerside Electric’s renewables can reliably supply the majority of the city’s energy.

In adopting this data-driven, AI-enabled energy management strategy, the city of Summerside is punching well above its weight class.

It became the first electric utility in Canada – possibly in North America – to use AI for real-time, automated energy dispatch. Other electric utilities are sitting on a wealth of data that can be leveraged by this type of energy management system. This ability to predict and optimize energy has the potential to release the throttle preventing broader renewable energy penetration worldwide.

The Peak of Service

by Brian Burks

One aspect of my job that gives me great satisfaction is providing on-site support for my wind customers. I don’t know too many other STLE-Certified Lubrication Specialists out there that are climbing wind turbines to provide up-tower consultations for their customers.

It also gives me an excellent perspective from which to educate customers and service providers on best practices that have been crafted over thousands of oil changes.

Before you even get on-site, you have to be armed with the proper training and certifications needed to climb 80 to 100-plus meters to the nacelle of a wind turbine. Some of the best-trained engineers learn at a purpose-built training facility, where they “learn the ropes” of wind turbine rescue and evacuation.

Regular tower climber certifications, recertifications, and rescue and evacuation drills make sure these skills stay sharp. Safety is paramount, especially when self-rescue or peer-assisted rescue are the only options should things go sideways far from the reach of traditional first responders.

Oil changes at heights are no small task. When an engineer first arrives on site, it’s important to sit down with the site operator and contracted service provider to make sure everyone is on the same page when it comes to understanding the procedure.

It can benefit all parties to have detailed written procedures for the various wind turbine platforms on the market, so you can run through each step. The goal is to remove and flush out as much of the old oil as possible to create the best environment inside of a wind turbine gearbox for the incoming new oil.

Skipping any one step can risk the cleanliness of the new oil and post oil change oil analysis results. All operators should pull post-oil change oil samples to verify the effectiveness of the oil change. These oil sample analysis reports should also be retained in case of any future warranty claims.

After the initial procedural review, it’s off into the field to approach the first turbine to be climbed.

SEPTEMBER•OCTOBER2020 /// www.nacleanenergy.com

The first challenge that typically presents itself is the environment. I have had the pleasure of consulting with customers around the globe. I’ve watched as a sandstorm barreled down on me from my perch out the hatch of a nacelle of a wind turbine near the Gobi Desert. I can tell you from personal experience that it’s not easy keeping dirt particles from contaminating the gearbox and new oil; it can only be done through effective procedures and well-protected oil exchange equipment.

I’ve endured the heat of the wind farms in the savannah of Brazil (staying hydrated is key when summiting wind turbines in that beautiful region).

I also remember nearly getting a rental car stuck in copious amount of mud while visiting a German wind farm during a particularly rainy visit; those installations presented an additional logistical challenge as they are somewhat segmented and often required significant travel through different farm fields to access each turbine.

Once arriving at the turbine, the safety plan for the day is coordinated with the service provider.

As a consultant, you want to make sure to stay out of the service provider’s way, while at the same time ensuring the service provider team is trained and checked on best practices to provide the customer with the most efficient and highest quality oil change. After preparing and packing the tools and equipment in lift bags, they are hoisted to the nacelle. Once the safety equipment check is complete, it’s time to don a harness

and begin the ascent to the top of the wind turbine. Consider yourself lucky if you happen to encounter a newer unit that comes equipped with either a lift or a climb-assist system on the ladder to aid the ascent, but this is still a luxury most towers donâ&#x20AC;&#x2122;t afford. It really is a great way to start the day though, stretching the lungs and getting the blood pumping as you burn through whatever breakfast calories you were able to scavenge at the hotel that morning.

Once settled at the top, there is not much time for a break as the real work begins. Tools are organized and staged to ensure efficiency, while hoses are hoisted up from the oil change truck below. The first step of the oil change includes draining the oil through a dedicated waste hose. This draining process is typically aided by a vacuum system that boosts the drain speed by establishing a negative pressure inside the waste oil tank back on the ground. Next, the oil filtration and circulating system is

disassembled at certain points, drained, and cleaned of all oil and any residual deposits that can be reached; this includes filter housings and thermostatic valves. After the interior gearbox housing is washed down with sacrificial flush oil and the gearbox is filled with additional flush oil, the unit is run-up under controlled conditions to fully flush the gearbox and oil circulation system.

Once this is complete, the flush oil is drained to a dedicated tank on the oil change trailer to be reused on the next turbine. Lastly, the final fill oil is pumped up a dedicated hose and into the gearbox, where it likely will see continuous service for the next 10 years or more.

Providing up-tower consultation services is not common in our corner of the wind industry.

Traditionally, the lubrication challenges of the wind industry were approached as no different than any other industrial application. In fact, it pays great dividends to attack these challenges side by side with operators and service providers at the point of lubrication up in the nacelle. The view from the top isnâ&#x20AC;&#x2122;t half bad to boot.

Out of Sight

Submarine cables are crucial for offshore wind growth

by Maxime Toulotte

GLOBALLY, OFFSHORE WIND FARMS ARE AN INCREASINGLY

One of the challenges with export cables is that carrying a lot of power also generates heat inside the cables. To ensure reliable performance, the insulation of any cables cannot be heated above a certain threshold of temperature for extended period of times. For AC cables, 90⁰ Celsius is the threshold above which the crosslinked polyethylene insulation will degrade. The heat must be thermally dissipated - this is helped by the cool environment at the bottom of the ocean where the cables lay buried.

Because the power carried by export cables in operation have steadily increased over time (~400MW AC, >900MW DC), the issue of heat dissipation has become more and more critical. This has forced operators to monitor the temperature of the export cables in operation to detect if any parts of the cables come under stress, or are subject locally to variations in ambient temperature or change in thermal dissipation conditions. Temperature monitoring is done by incorporating optic fibers inside the export cables, and connecting those fibers to a distributed temperature sensing system (DTS) that uses the fibers as linear sensors. These Bottom-fixed offshore wind farm and submarine electric additional safeguards represent only marginal costs for the export cables, and power cables technology have the added benefit of allowing end-to-end data communication between the The outer continental shelf off the East Coast possesses the same strong winds and extended substation offshore and the one onshore that connects to the grid. shallow waters as the North Sea.

Export cables carry a lot of power at a higher voltage than ever before – between 220kV and 230kV for alternating current (AC) or 320kV for direct current (DC). They are made of copper or aluminum conductors electrically insulated with a crosslinked polyethylene. Their The looked over last step: Cable Installation insulation must be protected from moisture with a stringent water barrier. That barrier is made Once the cables have been engineered, manufactured in very long lengths, and by extruding a layer of lead (called lead sheath) over the cable insulation. On top of that layer, a tested for the required maritime qualities outlined above, they will need to be laid polyethylene jacket is added to protect the lead sheath integrity and block lead migration.

A critical component to their deployment, and the success of the offshore wind industry, will be the unseen submarine cables that deliver the clean energy to the mainland. popular source of cost-effective and dependable renewable energy. The United States has begun to harvest the strong winds off its coasts to build out this industry; from a modest 30 MW currently in operation, East Coast states have issued policies targeting 25 GW within the next decade. By summer 2021, 9.7 GW will have been awarded in the Northeast (New York, New Jersey, Massachusetts, Connecticut, and Rhode Island). For the Mid-Atlantic and Southeast, developers have already outlined nearly 6.8 GW in incremental opportunities across North Carolina, Virginia, and Maryland. This growth and market opportunity will create a robust U.S. supply chain to supply and install the components necessary for an offshore wind farm.

As majestic white turbines begin adorning coastal landscapes beyond the horizon, key components to the game-changing potential of offshore wind energy lie unseen, beneath the waterline. These are the high voltage submarine cables that will export the sustainably generated energy to the electric power grids onshore – sometimes hundreds of miles away.

2020 New York New renewable development opportunities abound

by Anne Reynolds

Here in New York State, the clean energy horizon is looking closer every day. Mostly due to a new round of solicitations tied to historic climate legislation, and what we expect will be improved siting rules for both wind and solar, the case for optimism keeps growing.

INTELLIGENT WEATHER MONITORING. KEEP YOUR TEAM SAFE AND MAXIMIZE PRODUCTIVITY.

SEPTEMBER•OCTOBER2020 /// www.nacleanenergy.com

On July 21st, New York State announced a new, record-setting round of solicitations for renewables development.

For offshore wind, the NYS Energy Research and Development Authority (NYSERDA) is seeking up to 2,500 megawatts (MW) in a new request for proposals (RFP), as well as complementary multi-port infrastructure investments, which will bring the state’s total port development commitment to more than $400 million in public and private funds. As the Governor likes to point out, this is the largest commitment to offshore wind in the country. If all goes as planned, New York will strengthen its claim to being the hotspot for offshore wind development in the U.S. Another great component of the July 21st announcement was NYSERDA’s 2020 Clean Energy Standard solicitation, designed to procure 1.6 million MWh of wind and solar, creatively coupled with incentives to integrate battery storage into projects. Meanwhile, the New York Power Authority

abandoned commercial sites, brownfields, and landfills).

Despite the COVID-19 health crisis, the CLCPA-mandated Climate Action Council has begun to meet virtually, state agencies are hard at work, and there is every reason to believe ambitious targets will be met. It’s encouraging that the post-pandemic horizon includes economic revitalization strategies built on clean energy targets.

(NYPA) issued its own RFP to procure 2 million MWh. Working together, NYSERDA and NYPA are aiming to support the construction of 1,500 MW of wind and solar projects. Once procured, this will be a major step toward the State’s goal of generating 70 percent of our electricity with renewable sources by 2030.

Renewable energy solicitations in New York already required the payment of prevailing wage in construction, and the 2020 RFPs added a new priority for low-income and environmental justice issues. Proposals must include robust public involvement plans for localities and host communities. And, reflecting the most significant development in the new Accelerated Renewable Energy Growth and Community Benefits Act, projects over 20 megawatts are eligible to go through the revised permitting process currently being developed by New York’s new Office of Renewable Energy Siting (ORES).

Anne Reynolds is the executive director of the Alliance for Clean Energy New York, and a state Senate appointee to the Climate Action Council.

As directed by the new Act, NYSERDA also launched a “Build Ready” program.

The plan, which is moving ahead and should be ready next year, calls for collaboration between NYSERDA, local authorities, and stakeholders in finding appropriate sites. NYSERDA will secure permits, leading to auctions of up to six sites per year, hopefully speeding up development and construction in hardto-develop locations (such as dormant electric-generating plants and other former industrial properties, or existing or North American Clean Energy

Retractable horizontal lifeline

Pure Safety Group introduces the Guardian Retractable HLL (horizontal lifeline) for use in either fall arrest or fall restraint applications. During a fall, the Retractable HLL will deploy an extending metal energy absorber designed to reduce peak loads to anchorage structures. The new Retractable HLL can also be used as part of a fall restraint system, which prevents the worker from reaching the leading edge of a fall hazard.The main component of the HLL is a 60ft galvanized cable horizontal lifeline, which is durable yet portable, and designed for temporary use. When it has been involved in a fall, its energy absorber clearly indicates that to the user.

Other product features include a single direction, tensioner handle that prevents accidental releases and folds down to lay flat along the unit, secured by a magnet to prevent work interference, and handy carry handle. The HLL’s hex shaft can connect to a drill to speed retrieval of the lifeline, and its extremely low deflections create low fall clearance for users. The stainless steel housing and handles are corrosion resistant, which extends the life of the product. Quick and easy to install, the HLL can accommodate two workers at the same time, at a weight of 130 – 310lbs. per worker. The Guardian Retractable HLL meets OSHA standards 1910 and 1926 Subpart M and is made for use in any industry where workers are at height.

REsurety has launched its REmap information service. The REmap tool integrates weather and power market data at a vast scale, calculating hourly financial performance for 15,000 operational and greenfield locations, which REsurety uses to provide clients with the industry-wide context and site-specific depth of insight needed to make better decisions faster.

Cordless torque multiplier

The Cordless Torque Multiplier (CTM) from Snap-on Industrial is a heavy-duty tool capable of delivering between 250 and 3,000ft-lb of torque, and is suitable for anywhere power isn’t available or elimination of hoses and cords makes for a safer workplace. The CTM is a transducer-controlled, battery-powered torque tool designed for applying torque with an accuracy of +/- 3%. The tool employs “intelligent joint sensing” technology that continually measures the joint during tightening and, when necessary, deploys dynamic braking to avoid torque over-shoot due to motor inertia. The CTM allows two-way communication via Bluetooth for live streaming data from the tool, and it can save and download up to 3,000 time- and date-stamped readings via USB cable.

Conversely, information can be sent back to the CTM, such as tightening sequences, to aid the technician. Data can be output in CSV format to communicate directly with an end user’s own data management system. Additionally, the CTM can communicate with many smart devices, such as mobile phones and tablets, which enables the ability to send tightening specifications from handheld devices and store torque results on the cloud.

WHERE COLOSSAL, LOW-SPEED BLADES MEET EFFICIENT, HIGHVELOCITY CARGO HANDLING Twenty years ago, a 16-meter wind turbine blade was considered a long blade. The Port of Vancouver USA recently handled 77-meter-long blades—the longest ever imported into North America—nearly 5x longer than blades from two decades ago. Wind turbine size has increased in parallel with demand for wind components throughout North America. Any shipper’s list of port selection criteria has to include the laydown capacity to safely and efficiently handle such oversized cargo.

With its combination of favorable West Coast location, available laydown space, exceptional equipment and infrastructure and experienced labor force, the Port of Vancouver USA has a track record of success for handling wind energy components into the US and Canada.

Location and capacity Just over one hundred miles up the Columbia River from the Pacific Ocean, the Port of Vancouver USA enables shippers to bypass the congestion of other coastal ports. In addition, the port lies at the nexus of two interstate highways and a continent-spanning rail network, providing direct access from Asia to the US Midwest and Central Canada.

In contrast to most other West Coast ports, the Port of Vancouver USA also has vast amounts of acreage available for marshaling and short-term storage of large wind components. The port’s Terminal 5 facility features more than 80 acres of laydown space immediately adjacent to the deep-draft shipping channel.

Experience and flexibility The Port of Vancouver USA has more than 18 years of experience handling the transit of wind components bound for Eastern Washington, Oregon and Canada. In-depth knowledge of handling procedures, fixture types and other manufacturer-specific requirements allows the port to rapidly, efficiently and safely accommodate the full array of component types, sizes and designs.

Velocity and certainty The Port of Vancouver USA offers logistics professionals the hard-to-find balance of fast and efficient cargo handling along with the peace of mind that components will be handled safely. The operators of the port’s two heavy-lift Liebherr cranes are experts in engineered and tandem lifts, plus representatives from heavy-haul trucking companies are on-site to manage cargo movement.

Considering all the advantages the Port of Vancouver USA offers the wind energy industry, it comes as no surprise that the port will handle more wind energy shipments than any other US West Coast port in 2020.

Overcoming the Barriers to Energy Storage Interconnection New DOE-funded project will develop solutions to the challenges of storage interconnection

by Nicole Wilson

The energy storage industry has advanced rapidly, demonstrating the critical role storage technologies have to play in enabling a 100 percent clean energy future. But while energy storage has become an integral component of the clean energy sector, multiple barriers still remain in its deployment. Across the U.S., the process of connecting storage to the electric grid continues to be sluggish, complex, and unclear due to lack of clarity in relevant policies.

Fortunately, a new project supported by the U.S. Department of Energy Solar Energy Technologies Office is bringing together key players to tackle this challenge. The project, called BATRIES (Building a Technically Reliable Interconnection Evolution for Storage), will identify and address the regulatory and technical barriers to storage interconnection, and develop solutions that will pave the way for rapid and safe deployment of storage on the distribution grid.

A team of partners led by the Interstate Renewable Energy Council (IREC)—a facilitator of clean energy regulatory reform in states around the country—is working to simplify the interconnection process for standalone energy storage and solar-plus-storage projects.

“Energy storage technology is on a fast track to becoming a vital component of the country’s clean energy transition,” explains project partner Sky Stanfield, an attorney who represents IREC in interconnection and energy storage regulatory proceedings. “Interconnection policy is going to have to accelerate its evolution to keep up with this technology and to prevent barriers to its deployment. The time is now to identify and correct these issues.”

Energy Storage and the Barriers to Interconnection

Energy storage solves a key challenge of renewable energy sources like solar and wind: intermittency. By allowing renewable energy to be stored for use when the grid needs it, storage enables significantly higher penetrations of renewable generation on the grid. It also enhances grid resilience, and allows homeowners and businesses alike to increase energy independence, lower costs, and reduce their carbon

footprint—expediting our transition to a low-carbon energy future.

Today, a significant and rising portion of U.S. solar contractors are offering energy storage alongside solar arrays, and policymakers and grid operators are increasingly pursuing energy storage solutions. There are at least 24 GW of energy storage installed in the U.S., according to Energy Storage Association (ESA)’s 2019 report, and ESA predicts an additional 35 GW of new energy storage to be installed by 2025.

However, while most U.S. states have established explicit interconnection policies for solar, far fewer have addressed energy storage directly. “In many states, if you propose a system with solar-plus-storage, the rules about how to interconnect to the grid are not at all clear,” says Larry Sherwood, IREC President and CEO. “That creates a lot of uncertainty for developers, which increases costs and may scare them away from certain markets. As a result, the full benefits of storage are not realized.”

“Establishing best practices for the interconnection of storage to the grid is critical to sustaining market growth and enabling significant clean energy deployment,” Sherwood said. “We hope this project will serve as another step to making a 100 percent renewable energy future possible.”

Its fact-based regulatory policy engagement relies on public and private support to develop and advance the regulatory reforms, technical standards, and workforce solutions for the streamlined integration of clean, distributed energy resources.

IREC /// irecusa.org

Compared to other distributed energy resources (DERs), energy storage has a number of unique characteristics, and requires specific interconnection guidance for storage projects. For instance, energy storage customers are able to control when they export energy, and systems can be designed with the capability to limit or prevent export onto the grid altogether.

As a result, the best practices for how to analyze the grid impacts of energy storage differ compared to how other DERs are studied for interconnection approval.

Substantial work remains to ensure that state interconnection procedures require utilities to study energy storage projects in a way that recognizes the capabilities of these systems to mitigate grid impacts.

Regulatory guidance and proactive policies will be needed to lay the foundation for near-term and long-term market growth.

“Without this level of sophistication in the study process, we are likely to see utilities requiring interconnection upgrades that will be unnecessary and result in significant cost barriers for projects,” Stanfield explains.

Building a Technically Reliable Interconnection Evolution for Storage

In addition to IREC, the BATRIES project team includes the Electric Power Research Institute (EPRI), the Solar Energy Industries Association (SEIA), the Energy Storage Association (ESA), the California Solar & Storage Association (CALSSA), utilities, and other industry experts.

Over the next three years, the project team will create a nationally applicable toolkit of solutions that apply to diverse states and markets. The toolkit, planned for release in April 2022, will include resources such as model language for state rules and tariffs for distributed storage, as well as templates, checklists, and case studies.

Extensive training and educational outreach will be conducted to drive adoption of the resulting solutions in a majority of states. Regulators and utilities in at least 35 states are expected to be trained by the end of the project.

Pandemic Power Play

EU is proving a test case for a renewable energy dominated grid during COVID-19

by Andy Tang

SOON AFTER THE GREAT LOCKDOWN

began in Europe, energy demand and load on the grid decreased, drastically shifting utility dynamics. This period shows the possibilities of what a system would look like if the dominant energy source was renewables, and it solves the argument about whether they can provide enough electricity to power the system.

When global energy demand dropped, fossil fuel-based power generation plummeted, causing oil markets to temporarily crash, and coal-based power generation across Europe and the United Kingdom to drastically decrease.

An open data initiative that has been tracking energy usage and mix since early March 2020, has revealed the rapidly changing energy dynamics in real-time.

What powered the grid? A high concentration of renewables, combined with flexible power (storage), dominated the grid, while idling inflexible natural gas plants filled-in the gaps. Even as global demand decreased, total renewable generation remained at precrisis levels; a combined result of low electricity prices, long-term contracts, and renewables-friendly policy measures. A happy consequence of an unfortunate situation, renewables became a larger part of electrical systems across the globe.

All of this has resulted in unprecedented cuts to fossil fuel generation. The UK went entirely without coal for a record-breaking time period, over 56 days and counting at the time of this writing — the first the country has gone without it since 1888.

At one point, the UK even asked to lower nuclear output in order to balance its grid. The UK’s complete shutdown of coal reveals that the grid can meet demand without it. Coal use has instead become an economical decision.

Decreasing energy demand made existing renewable sources the cheapest to operate, which incentivized markets to

74

SEPTEMBER•OCTOBER2020 /// www.nacleanenergy.com

prioritize solar and wind, leading to the fossil fuel reductions. A recent report shows that, as revenue suffers, utilities try to get more electricity from wind and solar farms (which are highly automated and cost little to operate) and less from fossil fueled power plants.

Prior to COVID-19, Germany was running on 51 percent renewable generation.

During lockdown, it reached as high as 75 percent of operational capacity. The country generated a staggering 30 GW of solar on some days, with 40 GW of wind on the same day. Certain days forced the export of large amounts of solar power in order to balance the grid - reaching 14 GW at its highest. Spain experienced the same problem.

Flexible generation’s critical role

Increased use of renewables in the EU couldn’t have happened without flexible generation. Storage has outperformed all other generation assets, up 20 percent over last year. But it’s not enough. Grid operators still had to rely on inflexible natural gas generation to fill gaps in renewable supply. These plants needed to remain idling at all times in order to be ready for a dip in solar or wind. The main cause of renewable curtailment is the high cost of ramping fossil fuel plants up and down, and is likely why Germany was unable to absorb the country’s high amount of clean energy generation.

This sets the scene for the next decade of the energy transition. Energy storage providers can harness excess renewable generation during peak hours for later use. This creates a natural pricing arbitrage because of storage’s variability, which then creates incentives for flexible power operators; storage providers benefit from their ability to charge when prices are low and discharge when prices are high.

Cross-border collaboration

Increasing flexible generation improves renewable energy integration and decreases fossil fuel consumption. Across European markets, variable renewable energy generation is expected to become the largest share of capacity as early as 2023.

In an effort to balance this growth, flexible generative assets will be essential. It’s predicted that storage across all segments will grow from 3 gigawatts (GW) in 2020, to 26 GW in 2030, and 89 GW by 2040. The impact of increased flexibility will reduce the coal fleet from 60 to 40 percent of nameplate capacity.

Flexible energy storage with the capability to provide various parts of the energy value stack will thrive in markets with high renewable energy penetration, demonstrating their strong economics and capacity benefits to the grid.

This period also revealed that stronger connections between countries for cross-border collaboration is needed so that all of the renewable capacity can be utilized. Allowing power to flow freely between countries will help everyone navigate the energy transition.

Data found that when Germany had to curtail renewables at home, instead of shutting the system down, the country exported 14 gigawatts (GW) of extra renewable power generation to Norway, which has a more flexible system. Norway was able to shutdown other assets (mainly the country’s hydro plants), add Germany’s renewable power to its flexible storage assets, and then distribute it across the country. Similarly, Spain had to push out 5-6 GW of renewable power.

Germany paid the price twice for inflexibility: first by losing the cheapest energy, and then by having to pay Norway €80 MWh to take it. Those with inflexible systems will increasingly pay more for their power, while countries with flexible systems benefit because they’re able to shut down their own production and gain energy with negative pricing (i.e. get paid to take it).

It’s estimated that those with inflexible power systems will increasingly need to pay others to take their excess renewable power as high levels of renewable energy generation become frequent, which will drive energy prices down overall.

Using stronger connections across countries will enable energy to flow freely within the EU, prevent curtailment, and help all members run on larger amounts of renewable power - not just those with the generation capacity. Along with being able to store excess renewables, distributed battery storage can offer relief on congested grids; freeing up more capacity on transmission lines helps prevents wear and tear, allowing existing transmission capacity to better serve future grids.

Putting the economy to work

In the midst of this pandemic, renewables and energy storage are likely to play a role in recovery plans. The European Union released a proposed €750 billion ($825 billion) Coronavirus pandemic recovery package that aims to boost clean technology and energy value chains. This would allow more deployment of energy storage and other distributed energy technologies to provide economic and COVID-19 relief benefits. Research shows that renewable energy can directly and indirectly generate roughly three times as many jobs as comparable fossil fuel investments.

Decreased energy demand during the COVID-19 pandemic has afforded us an unexpected gratis opportunity to test renewable systems and discover how to technologically transition to a renewable-dominated grid. Let’s use this opportunity to build the infrastructure that’s needed to complete the transition to 100 percent renewable.

How Demand Response is Solving this Summer’s Energy Challenges

by Surya Panditi

This summer has proven to be incredibly challenging for our industry. Heat waves across the United States, coupled with more than 40 percent of the labor force working from home due to the pandemic, has led to historical energy shifts and unpredictable usage patterns.

This season of change has highlighted deficits and strengths within our energy systems. It has underscored the need for long-term modernization while demanding short-term solves.

Never has grid flexibility been so important, but the grid can’t be modernized overnight to keep up with these shifting market dynamics. As the industry adapts to fluctuating power demands, utilities and businesses should explore ways to expand their use of demand response and other flexible solutions that meet today’s energy needs while building the grid of the future.

While early predictions called for a steep drop in energy demand as businesses shut their doors in response to COVID-19, the millions of Americans working from home (as heat waves gripped the country) likely caused unexpected changes. Residential

AC tends to be less efficient than commercial systems in office buildings, and homes also tend to require more cooling per person than office space. Between shutdowns, remote work, layoffs, and school closures, people were likelier to be at home during what is expected to be the hottest year on record. This led to greater use of residential air conditioning, subsequently straining the grid.

At the same time, data showed that, while overall demand is still down, many companies’ facility demand peaks are actually higher than they were last year. The chart shown provides an overview of average energy demand and average peak demand from commercial and industrial customers, representing approximately 2 percent of energy demand across the U.S. and Canada.

To manage the ever-changing landscape, utilities are renewing their focus on demand response as a reliable resource for meeting customer needs in a cleaner and more cost-effective way.

Although this concept is not new, DR has become an increasing

portion of utilities’ resource mix in recent years, and has emerged as a hero this summer by alleviating grid strain, potentially avoiding power outages.

In the first few weeks of July, DR events were happening on a nearly daily basis.

1,260 MW (5,058 MWh) was dispatched across storage and demand response, nearly three times more than June (477 MW). The remainder of the summer and into fall, especially with an already active hurricane season, more potential grid disruptions are expected.

In addition, market trends (like load growth and the retirement of older, traditional sources of generation) are creating the need for more capacity.

For utilities across the country, DR has provided a timely option for filling resource gaps, while also playing an important role in sustainability efforts. DR and other flexible solutions have helped utilities avoid the need to turn on peaker plants during summer’s periods of high demand, reducing carbon emissions during what could have otherwise been a time of heavy pollution.

This year has brought a significant change in the role of storage as a DR asset; there’s been a five-fold increase over last year in storage sites being deployed during DR events, including California, Massachusetts, New York and Ontario. In New York City, electricity use has broken records from 2013, resulting in critical capacity

being dispatched from a front-of-the-meter battery storage system in Brooklyn, the largest operational battery system in New York City. So far this summer, the system has responded to 13 dispatch events for 52 hours, delivering more than 188,000 kWh to the grid.

The ability to enroll a storage system into a utility’s demand response program helps deliver maximum value on that energy asset and added benefits to the electric grid.

Electricity is no longer seen as a cost, but rather a revenue-generating service that simultaneously benefits the grid and the communities dependent on it.

Renewables combined with storage can also improve a business’ resiliency, while contributing to their sustainability efforts. Commercial battery systems coupled with renewables provide flexibility for the clean energy to be used over longer periods of the day, to help users ride through extreme weather events. These alternative energy options will allow facilities to store low-cost, clean electricity, and use it during peak demand periods and emergencies.

Reshaping the customer experience for EV drivers

Surya Panditi is Head of Enel X North America, which provides value-added services and solutions that enable businesses and communities to create, store, use, and manage energy.

Tritium has launched its Plug and Charge solution. The technology, leveraging the ISO15118 standard, enables an electric vehicle and charger to communicate seamlessly and authorize payments directly from the driver’s account, without the need for a card or RFID tag. The Tritium offering is available immediately for charge point operators to deploy on Tritium’s PK350kW DC High Power Chargers. The technology promises to reshape the customer experience (CX) for the driver and enable the once-siloed approach to charging payments to be broken down with disparate charging networks able to interoperate.

Drivers will be able to approach a charger, regardless of the charging network operator, and their charge session will be automatically and securely billed from the moment the charger plug connects to the vehicle. The Tritium Plug and Charge technology has been tested in a live setting at a number of its PK350kW DC High Power Chargers in Germany. The Tritium Plug and Charge solution has also been repeatedly tested at the Tritium E-Mobility Innovation Centre in Amsterdam, where automotive manufacturers have been able to test vehicles for interoperability with Tritium’s suite of DC chargers and software technologies, including Plug and Charge. As new vehicles begin to be rolled out and with them the technology to secure the cryptographic key on the vehicle side built into the vehicle itself, the technology will lead to a new CX era for electric vehicle drivers.

Grid modernization is the ultimate goal

The grid has traditionally been a highly regulated asset overlooked by technological innovation. However, innovative solutions brought to scale, and collaborating with specific market conditions, allow the grid to balance demand to keep lights on and costs low. Today’s DR programs, battery storage, and distributed energy resources as grid solutions can save millions of dollars in costly infrastructure overhaul. While these solutions help today, the industry must plan further and integrate IoT technology to ensure the long-term health of our power systems. This level of modernization enables customers and system operators to control where, when, and how electricity is used. With real-time situational awareness and preparedness, grid operators can manage the grid and limit the need for widespread outages.

The good news is that the industry can further the energy transition and build a stronger grid by thinking strategically about the value of resiliency, flexible solutions, and prioritizing alternative energy methods.

Electrical Systems ROI How to improve your return through maintenance and life-extension services

by Jill Howell and Nan White

Maximizing ROI – a common goal

The renewable energy market continues to expand as government incentives encourage project development, states establish renewable standards, and sustainable power-generation equipment costs decline. Increasingly, companies are leveraging diversified portfolios of energy sources (from both traditional and renewable energy systems) as they strive to reduce their carbon footprint and ensure uninterrupted power. System owners face many challenges - from power consistency and stability, to systems integration with traditional energy sources and the national grid. Careful consideration must be paid during all phases of a renewable energy project (design, construction, and ongoing operation) to ensure energy resiliency without compromising reliability and quality. Developers and owners rely on electrical reliability experts to evaluate grid interconnection compatibility, protection system coordination, power systems performance, and other factors to ensure system integrity and power quality. These experts help ensure all parties work together to address challenges and comply with industry standards, while maximizing return on investment.

Maintaining regulatory compliance with acceptance and maintenance testing

Renewable energy operations are regulated by federal, state, and security regulations and standards that must be met to ensure a safe and compliant renewable energy environment. Operators have to understand these standards and know when to apply them. Without this knowledge, projects may not get approved or pass inspection.

Acceptance testing and ongoing maintenance requirements are specified in detail within the NERC – North American Energy Resources Corporation, NFPA 70B – National Fire Protection Association, and NETA - InterNational Electrical Testing Association Standards.

These standards provide the requirements and guidelines to ensure power utility owners are building and maintaining safe facilities that deliver reliable power.

Leveraging Life-Extension Opportunities

As renewable power generation systems age and technology evolves, these systems will require life-extension services. Despite best efforts to maintain existing equipment according to the standards, the cost to keep these assets in operation will continue to rise.

Facility managers face many obstacles: • Conformity to industry standards • Obsolete protective devices, which may lack features that support multiple protection & control functions, arc flash detection, remote communication, and monitoring, or data logging and networking features • Increased maintenance and calibration intervals Facility managers are looking for cost-effective ways to extend the life of plant assets and return them to optimum operating levels. The best practice is to consult with an electrical reliability expert to evaluate the system and recommend a solution. These experts design customized plans to upgrade and retrofit existing assets with the latest technology, usually at a fraction of the cost of replacement. These plans include a combination of life-extension services.

Services include: • Visual and mechanical inspection • Cleaning and lubrication • Maintenance testing • Repair and replacement of worn or defective parts • Acceptance testing refurbished equipment Recondition Services As equipment ages, not only do components begin to wear, but insulation deteriorates, which leads to electrical leakage, tracking, and possible flashover. Damage is normally evident on the surface of insulating members - if it has not progressed to significant depths, it can usually be resurfaced.

Services include refurbish services, plus: • “As found” inspection and electrical testing • Complete disassembly • Worn parts replacement • Removal and inspection of arc chutes • Bead-blasting and polishing • Reconditioning of current-carrying elements • Reassembly Rebuild Services Rebuild services can renew existing assets at a fraction of the cost of replacement. These services are for switches, starters, contactors, and motor control centers.

Services include recondition services, plus: • Re-plating of steel components • Stripping and powder coating of painted steel parts • Replacing of hardware, bearings, bushings, and damaged or worn control wiring • Bench testing of components before reassembly • Re-varnishing of insulators

Retrofit Services Component upgrades can deliver advanced technologies to improve efficiency; enhance stability and communications; and increase personnel safety. Most upgrades can be retrofit into the existing system without disruption to service quality.

Breaker Retrofit Services Advanced circuit breaker technology can replace older equipment without disrupting existing switchgear. Most replacement breakers are designed to fit into the existing switchgear cells with minimal modifications, and will interface with the existing switchgear structure while maintaining safety interlocks inherent in the original design.

Low-voltage breakers can be upgraded with new solid-state trip units featuring digital communication, adjustable settings, and enhanced protection capabilities for improved operating efficiency. Retrofitted breakers can also be remotely operated and increase energy management capabilities, reducing overall operating costs.

Medium-voltage breakers are updated and retrofitted with vacuum and SF6 technology, delivering improved reliability and decreased maintenance intervals. The large, heavy arc chutes and hot ionized gases are eliminated, making the

retrofitted breaker much safer.

Interrupting rating time is also improved, as well as momentary and continuous current ratings, bringing them up to the level of typical replacement breakers.

Protective Device Retrofit Services Improved facility operation and reduced personnel risk can be achieved by retrofitting existing protective devices with new intelligent Microprocessor-based relays. Microprocessor relays offer many advantages, because they: • Require less maintenance and offer improved precision and reliability; • Provide advanced data capture functions and tools for postevent analysis; • Integrate with existing breakers and load interrupting devices; • Incorporate arc-flash reduction technologies for increased safety and equipment protection; • Support advanced communications and capable of integrating with SCADA and DCS systems; • Resist performance degradation or drift so there’s no need for periodic recalibration.

Transformer repair or replacement The growing trend to load transformers to higher levels is ultimately increasing the risk of failure. Experienced engineers can develop a solution to reduce failure risk and improving capacity and performance.

Services include: • Turnkey installation and replacement/relocation • Condition assessment • Assembly, vacuum oil fill, and testing • Busing repair and replacement • Load tap changer repair and replacement • Regasketing or leak repair • Insulating fluid/oil reconditioning • Cooling upgrades • Spare parts When considering any of these services, partnering with an independent electrical reliability expert will ensure that owners and operators are prepared to meet the challenges ahead. These experts are uniquely equipped to provide standard compliant, customized life-extension plans utilizing current technologies and proven maintenance practices, regardless of equipment age or manufacturer. Partnering with the right service provider is the key to an operation’s short and long-term productivity, serviceability, and ultimate success.

Security and Stability at the Coupling Point

by Brian Hill

The generation of power traditionally involved a small number of extremely large power stations. This market structure made it relatively easy to control power generation centrally, along with energy feeding into the grid. However, recent years have seen rapid growth in the number of decentralized Power Generation (PG) systems, which are becoming commonplace as the energy market transitions towards renewable energy.

This transition has led to a major increase in the number of small Power Generation Units (PGUs): Small and medium-sized businesses, municipalities, farms, and even private homeowners can generate power from renewable sources and feed surplus power into the grid. These PGUs range from small energy parks right through to individual wind turbines, biomass plants, combined heat and power units, and photovoltaic installations.

This new structure presents network operators with two major challenges: they must ensure grid stability at all times, and simultaneously fulfil strict supply security obligations.

Challenge 1: Stability

North American network operators are legally obliged to ensure the standard frequency of 60 Hz, slightly higher than the European 50 Hz. In the event of deviation, operators must intervene with primary and secondary control reserves within 30 seconds: They transmit adjusted energy demand to the PG systems, compensating for generated and consumed power in order to restore network stability. Without this measure, unforeseeable fluctuations and deviations would cause frequent power cuts.

With many small and medium-sized PG systems lacking the ability to be centrally controlled, coupled with the amount of inherent variability in energy production from renewable energy sources (namely wind and solar), these unforeseeable fluctuations have become an inevitability.

Figure 1: Overview of a power plant control system

SEPTEMBERâ&#x20AC;˘OCTOBER2020 /// www.nacleanenergy.com

Challenge 2: Security

The rapid growth of the renewable energy market - and its relatively new network and security infrastructure - has made it a target for cyber-attacks.

Cyber-attacks may involve anything from data theft to a complete system override, leading to potentially dangerous operative settings. If network security is breached, network operators may lose control over the grid. This could result in power cuts, power surges, or energy market manipulation.

One way for network operators to approach these challenges is to require the installation of a power plant controller between the power plant and the network.

A PG system can be comprised of a single energy source, or it can be varied (hybrid park) - consisting of wind turbines, combined heat and power units, photovoltaic installations, and/or biomass plants. The individual PGUs or subordinate power generation systems are combined at the Point of Common Coupling (PCC).

A power plant controller must be installed on the generator side. It is the interface between the PGU and the network operator, acting as the central component of the system. The PCC is the digital replacement of the former ripple control receiver.

The power setpoint for the entire plant is transferred from higher-level instances, such as network operators and direct marketers, to the power plant controller.

This measures the actual values of the PGUs and the grid, calculates the

Figure 2: Connection example featuring Bachmannâ&#x20AC;&#x2122;s Smart Power Plant Controller as a power plant controller for different power generation units

setpoints from the external requirements (active and reactive power) for the individual generator units, and then transfers this to the PGUs. Smooth communication between the power plant controller, the individual components in the system, and the external higher-level instances ensures that: - setpoints and setting procedures are observed at the PCC - the required quantity and quality of power is provided - the grid is stable - the energy park runs efficiently

Many park controllers can be integrated into hybrid energy parks consisting of many individual PGUs. If the controller is provided with a simulation model, plant operators benefit from improved flexibility and can save costs for plant certification, considerably simplifying the process. Commissioning is also simplified through web-based configuration and operation visualization tools (if available) â&#x20AC;&#x201C; this enables individual adaptions and operation monitoring and control from a variety of devices.

Standardization at the Point of Common Coupling

Bachmann electronic GmbH /// www.bachmann.info

In order to guarantee the security and stability required by the network, the plant controller market is rapidly becoming subject to standardization. Authorities worldwide are starting to introduce new regulations for power plants. In North America, for example, the North American Electric Reliability Corporation (NERC) has introduced strict regulations on cyber security and data protection.

Germany leads the way in Europe, having recently implemented an update to the Technical Connection Rules VDEAR-N 4110/4120 to regulate the power feed to the grid from renewable sources, allowing them to be integrated as decentralized units in existing networks.

The standard applies to all players in the energy market: network and plant operators, plant manufacturers, planners and designers, as well as component manufacturers. It stipulates that all operators of a PG system connected to the medium voltage grid, with a total output of 135â&#x20AC;&#x2030;kW or greater, must use a certified power plant controller at the PCC. Energy providers worldwide are recommended to select a park controller already in accordance with the German VDE-AR-N 4110/4120 TCR Medium Voltage, which guarantees network stability and security.
