North American Clean Energy March/April 2022 Issue

The great thing about having access to instant news is that you quickly learn the latest buzzwords. Wait, did I say great? What I meant to say is that I want to scream and tear out my own hair – or someone else’s – every time I hear a term being overused. Unfortunately for me, that term is “infrastructure”. My body isn’t capable of the level of eye rolling necessary for me to cope with reading or hearing it one more time. Word nerd that I am, I naturally looked up the official definition, courtesy of Merriam Webster, which describes the essential meaning of “infrastructure” thusly: the basic equipment and structures (such as roads and bridges) that are needed for a country, region, or organization to function properly. Even the Fern Hollow Bridge couldn’t take listening to Biden sell us yet another amazing and comprehensive infrastructure plan. I totally get it; I would have thrown myself over that poor bridge if it had provided more than a 3-foot drop to the ground. I’ll try not to bore you with origin stories. Instead, let’s go a few years back to 1998, when Bill Clinton debuted his $217 billion transportation infrastructure bill that helped increase the number of bike paths and provided upgrades to an interpretive music center (to help calm those of us stuck in traffic watching highway workers stroll past our line of cars?). Not even 10 years later, George W. Bush felt compelled to sign a 4-year, $286 billion transportation (ahem, “infrastructure”) bill. I bet Fern Hollow wishes it had received some of that “Bridge to Nowhere” money. After those pricey four years were up, Barack Obama threw his hat into the ring with his much-vaunted $831 billion “American Recover and Investment Act” that he signed into law in 2009. Allegedly, the nation was standing by, shovel ready, though what exactly we were we were shoveling varies depending on who you ask. Throughout Donald Trump’s turn in office, he proposed $7.5 trillion on infrastructure improvements, but he got kicked off the playground and nobody agreed to anything.

I don’t recall George Jetson having to steer around power lines, or Smokey the Bear citing decaying towers propping up poorlymaintained transformers as the cause of forest fires. I was happy to help prevent the fires, but I took his “only you” with a grain of salt; how could I convince a massive California utility to secure basic infrastructure before weighing down the grid with ambitious plans to electrify ever-growing fleets of school buses? Given his propensity to harken back to his good old days, I’m fairly certain that Joe Biden either played with or has knowledge of Lincoln Logs. Can you imagine him haphazardly throwing some pieces into the carpet and then building a fort on top? He wouldn’t get too far before it all came crashing down.

By the way, Webster’s goes into a more fleshed out definition of “infrastructure” that includes: the resources (such as personnel, buildings, or equipment) required for an activity. Presumably, that encompasses things like cargo ships and dock workers. And maybe even people to unload trucks at whichever destination is fortunate enough to receive new stock. Rube Goldberg is turning in his grave watching the sputtering machine that is our current infrastructure.

On a final note, reading reports of the dozens of private jets that fly into and out of Los Angeles for that town’s latest star-studded gala already has me on edge without those individuals tweeting mid-air about how everyone has to do their part for climate change. I’ll tell you one thing, if Pete Buttigieg ever succeeds in lowering the speed limits for the rest of us, I’ll be first in line to hitch his vehicle to an anchor from one of those algae-encrusted barges waiting off San Pedro.

High Carbon to Low Carbon Careers

The case for putting

skills to use in the wind industry

by Richard Smith

Decades ago, the perception of wind technology inspired some predictable skepticism as a “novelty” form of energy. Fast-forward to 2022, and the reputation of wind turbine innovation as trailblazing and ground-breaking is not unearned. In recent years, these assets have become exponentially more efficient, productive, versatile in location, greater in scale, and greater still in blade size.

With advances like floating offshore turbines and articulated wind columns, a broader spectrum of disciplines has migrated towards the wind energy industry on the engineering, design, and construction side. And the advances don’t stop there; this steady growth has spawned a variety of sub-sectors including offshore wind support vessels, underwater cable laying, condition monitoring systems (CMS) for blade health and the digital solutions that accompany them, among many more. Just as the expansion to offshore has tapped into the maritime industry, the increasing digitalization of turbine systems and their coordination has allowed a variety of professionals with prior expertise outside of mechanical engineering (computer programmers, data scientists, and data analysts) to flourish in the industry as well.

Surprisingly, the “ultra-modern” turbine design we are familiar with today is over 30 years old, and even older in concept. Despite the progress made in the field, the mechanical reality is that wind turbines are not as complicated as people might think.

Rather than increasing the base complexity of the wind turbine concept — which is, at its core, a simple conversion of rotational force into electrical energy — developments have principally been additive and auxiliary, focusing on configurability, reliability, and streamlining an already straightforward formula.

Instead of causing a false sense of career instability, the rapid expansion of the wind industry should instead be seen as an opportunity to put specialized learning from other sectors, and particularly high-carbon careers, to use for a greener world.

As a Principal Mechanical Engineer with 13 years’ experience in the global wind industry, I’ve worked on onshore and offshore wind farms across the UK, and in Europe, North America, China, and Mongolia. I previously worked in highcarbon industries, including aerospace propulsion development for Rolls-Royce and Boeing, and chassis and powertrain development for various automotive OEMs. Surprisingly, there was no substantial upskilling necessary in his transition from aerospace to wind.

Wind technology is an amalgamation of foundational engineering disciplines; compared to aerospace, it’s much simpler. It’s just components, and mass, and forces, and torque, and power, and volts, and amps — just the same as we get in any other engineering discipline.

Due to this fundamental simplicity, I believe that now, more than ever, there’s exciting opportunity for new entrants to the wind industry, which itself will benefit from an influx of young workers whose entry is not limited by a requirement of decades of experience, and who have a freshly cultivated, fundamental grasp of engineering skills. Even so, there seems to be a reluctance to get involved with wind turbine engineering by experienced individuals in other careers, as they assume wind must be too different or complicated.

To those with experience: the work surrounding wind turbines is as broad in scope as you can imagine. Civil engineering, cable-laying,

Solar’s New Herd of Asset Managers

The social, environmental, and economic benefits of solar grazing

by Chad

On a warm day in July of 2021, upon arriving for a routine operations check of a 750kW community-scale solar project in Royalton, Vermont, the asset manager was greeted by a friendly and curious herd of sheep. After thoroughly vetting the new arrival, the herd was content to get back to its work of keeping the vegetation at the site in check. This scenario is a great example of the mutually beneficial relationship between agriculture and the solar industry. Sheep are more than happy to do the work that noisy, fossil fuel-powered mowers used to do on this site, while also taking advantage of the shade under the panels for rest.

A growing partnership is developing across the solar industry, with farmers and other landowners on track to lease more than 2 million acres of land in the U.S. for community and utility scale photovoltaic solar projects by 2030. Accelerating the deployment of solar arrays - beyond the 300,000 acres of farmland currently hosting solar projects - to reach these projections presents a tremendous opportunity for farmers and local communities.

The partnership between the solar industry and the agriculture sector has led to a broader trend emerging for solar and agricultural industry that includes a critical role for livestock: agrivoltaics. Herds of sheep are now providing solar grazing services that offer a number of benefits to the solar project itself, as well as the farm and local community.

Enter the “electric” sheep

Sheep are the most common solar grazing animals. They enjoy the shade of the solar panels on hot days, napping and grazing in locations that human-operated mowers would struggle to reach. They are resourceful and discerning foragers, unlikely to chew on wires (like goats) and not large enough to damage racking (like cows). Their size also allows them to walk under the panels and in and around above ground equipment to search for vegetation that might otherwise become a shady nuisance for a solar array.

nearly 3,400 individual dairy farms as production was largely ceded away from smaller family farms into large, agri-business operations. The co-location of solar generation projects and agricultural production on Vermont’s working landscape provides an example of the numerous social, environmental, and economic benefits for farmers nationwide. In Vermont and elsewhere, where farmers have been faced with challenge after challenge, solar affords an opportunity to diversify revenues while keeping the land in active food production. Leveraging income from PV generation provides a unique opportunity to de-risk and diversify farming operations so as to maintain financial viability for farmers.

Additionally, preliminary research out of Minnesota finds that implementing managed sheep grazing at solar projects significantly increases soil carbon storage and other nutrients important for plant production. Early estimates show, and long-term study may confirm, that an acre of recovering agricultural soil installed with native plants may result in one ton of sequestered carbon per year, and that can possibly accumulate for 12 to 15 years before saturation is reached. And in a future economy where carbon sequestration will be monetized, this can result in an additional source of revenue. Utilizing sheep as a vegetation maintenance tool can reduce the overall carbon footprint of the maintenance of the solar energy project, maintain a tie to the local agricultural community, build soil health, and enhance soil carbon sequestration.

A new agrivoltaic economy

With solar grazing, the vegetation at solar sites becomes a source of nutrition and a pasture for sheep, which can in turn support a larger domestic market for sheep and lamb products in the U.S., where nearly 50 percent of the lamb consumed is imported. There is a growing interest in local food production that puts a premium on locallyproduced lamb, dairy products, and specialty wools, further underscoring the value of solar grazing with sheep.

Solar grazing keeps farmland in active food production

Solar grazing can also contribute dairy, meat, and wool to regional markets where agricultural production is in decline. For example, from 1969 to 2020, Vermont lost

Solar projects can provide additional agricultural value beyond the social, economic and environmental benefits of co-located sheep grazing; there is a growing number of agricultural activities that are well suited to pair with solar generation. These include planting pollinator-friendly ground cover for honey production, growing mushrooms and other vegetable crops, and keeping chickens and other poultry. Depending on the project location, there are many opportunities for solar and agricultural collaborations. In short, the growing agrivoltaic economy will allow a given area to harvest the value of the sun in multiple ways — as fuel for crops, pasture for sheep, and as a source of carbon free renewable energy.

Linear vs. Circular Economy

by Philip Schwarz

Ratty clothing, empty milk jugs and laundry detergent bottles.

What truly is waste?

Whether we realize it or not, the answer to this question impacts our day-today lives and increasingly shapes our economic and environmental futures. It also has everything to do with linear vs. circular economies.

Take, make, waste—that’s the crux of a linear economy. We take resources from the earth. We make stuff, use it for a while, then throw it away. And when we replace that stuff, the take-make-waste system perpetuates. Thus, the linear economy model packs a one-two punch to American economic prosperity and environmental health.

Consider, for example, the linear life of a single-use product in a single sector: wood pallets used by the solar industry. In 2020 alone, an estimated 1,580,000 wood pallets were used to ship solar PV modules in the United States. That same year, the linear economy of wood pallets used for solar shipping resulted in 60 million pounds of wood waste in U.S. dump sites.

But that isn’t the whole picture. A lot more happens between forest and landfill.

Nearly every phase of a wood pallet’s life cycle creates waste and negatively impacts the environment. This includes the heavy machinery used in sawmilling, toxic chemicals used to treat and adhere the wood, and the many stages of transportation discharging greenhouse gasses (GHG) and other emissions.

Some of these chemicals, such as methyl bromide, are known to be toxic to humans, and believed by scientists to break down the Earth’s ozone layer.

In addition to logging, sawmilling, and manufacturing, wood pallets require transportation—lots and lots of transportation. Pallets go from forest to sawmill, sawmill to manufacturing site, manufacturing site to PV module manufacturers, PV module manufacturers to job sites, and finally on to landfills, where they will sit for 13 years until decomposed.

Take. Make. Waste.

A linear economy devalues our increasingly limited natural resources to profit off waste. In fact, the linear economy model very successfully yielded economic growth throughout the 20th century —unsurprising, perhaps, given that Americans throw away 4.5 pounds of trash per person, per day.

(In case you’re curious: at this rate, the U.S. will collectively run out of currently active landfill space in just over 60 years. Some states will actually run out in the next 5 years. )

From an environmental, not to mention quality-of-life, standpoint, it’s easy to see how this is untenable. Experts, too, are

beginning to recognize the unsustainability of a linear economy itself.

With our rapid population growth, we’re destroying the ecosystems on which businesses and society depend. While we’re at it, our throwaway culture is depleting and degrading Earth’s bank of natural resources at an accelerated rate —the same natural resources needed to sustain a linear economy.

What are we doing with all those increasingly limited, increasingly valuable resources?

We’re burying them in landfills.

By contrast, a circular economy recognizes the value in our ever-diminishing natural resources. Circular economic practices intentionally design waste out of the picture, preferring to keep these resources in use for as long as possible, optimizing value before recovering and regenerating them at the end of a useful life.

To this end, a circular economy understands that one company’s discarded material is often another company’s ideal input material. Encouraging cross-sector purchase or trade of surplus materials such as plastics, packaging, and construction materials converts “waste” into cost savings and additional income for large and small businesses alike. In these scenarios, one company’s trash truly is another’s treasure.

What’s more, the circular economy model mimics patterns found in nature, where there is no such thing as “waste.” It ensures the possibility of economic growth despite resource constraints, potentially creating hundreds of thousands of jobs and generating millions in economic value while restoring the ecosystems and natural capital on which global societies depend. It’s a clean, efficient system with real-world impacts.

In other words, a circular economy just makes sense—especially for industries built on the principles of sustainability and green living. Like the solar industry.

With its push for renewable resources and clean energy, the solar industry should be pioneering circular economic practices at every opportunity, not dumping millions of pounds of wood waste into landfills. We should be the first industry to proactively engineer waste out of our production, installation, and shipping practices. When discarded material is unavoidable, we should steward that material as a useable resource into its next life.

Because ultimately, the real difference between linear and circular economies is a question of vision and value: what truly is waste? Simply put, waste is opportunity. Waste is value. It’s a path toward positive change.

How to Prepare for the Solar Boom

by Amanda Amos

In 2021, solar represented 54 percent of newly-added electricity generation capacity, compared to 8 percent in 2011—a more than 600 percent increase. Federal, state, and local regulations and renewable energy goals will continue to drive growth in the solar market through the next decade. Companies in the solar market are bracing for a flood of work. Careful planning, training, and capacity building will be required to absorb that work. This article examines three considerations that will be essential to supporting the continued growth of solar generation capacity.

1. Planning and Pre-planning

Solar work presents planning challenges both in the prework and construction phases of the project. The supply chain issues triggered by COVID-19 have not spared the solar industry; this should to be considered during the prework period. With material delays throughout the country, orders need to be made early and extra capacity needs to be built into planning. For instance, utility-scale solar requires extensive use of specialized equipment like pile drivers. Purchasing additional machinery to maintain capacity is a prudent step given current conditions.

During actual construction, pre-planning of work for the next day or week is a vital practice. Solar installation is complex with many, many moving parts. Often, these parts are order-dependent, meaning if one function stops, the entire train stops, bringing the job to a halt. Therefore, making sure that detailed plans are created, adjusted, and readjusted according to changing conditions is important to keeping work on schedule.

2. Workforce

Solar projects are demanding, with high people hours and often hundreds of new hires over the course of construction. This means that safety, recruitment, and communication all require special attention.

Many utility-scale solar projects are executed in harsh, desert environments. This type of work setting requires special safety training—heat illness training is non-negotiable. Having been involved in a project where daytime temperatures regularly exceeded 120 degrees, I know firsthand how important it is to start early in the day to beat the heat, shut down early to avoid the hottest portions of the day, provide cooling stations and towels to the crew, and ensure constant monitoring and check-ins for team member safety.

The battle for talent is an issue across the construction industry, and solar installation is no exception. In fact, the nature of the work creates added difficulties for recruitment. First, there is the scale of the projects—a 3,000-acre jobsite needs a lot of people. Second, there is the mobile nature of the work; key clients are likely to have projects around the country, and capturing that work requires the development of repeatable processes to train new workers and providing incentives to retain them. Having a mobile workforce is a major differentiator and a key to success.

Finally, communication with the workforce needs to be clear and consistent, especially when it comes to pre-planning work on the construction site. These projects have many moving parts, unfolding over enormous jobsites. Without focus and dedication, communication failures can lead to issues that disrupt or delay work.

3. Technology

Effectively identifying and deploying new technologies is a crucial driver of success in large-scale solar installations. Projects have grown more extensive in the past decade, and they will likely continue to

grow. An average new utility-scale installation is approximately 250MW, up more than 100 percent in the past decade. Using the right technology ensures that these increasingly large projects are completed in compliance with exacting specifications.

Locational awareness is essential for everyone on the jobsite: lasers for precise line and grade work and GPS tracking for equipment. Technology also supports safety and communications needs. Using tablets to communicate daily work plans, execute quality control, and provide access to safety information is more efficient and timelier than in the past.

Lessons Learned

Solar installation is a market with exceptional potential for growth, and companies need to be strategic in how they approach these new opportunities. Another important consideration is clearly defining the type and scope of projects to pursue. Maintaining close coordination between estimating and operational teams will ensure that project pursuit is focused on work where the company has the proper knowledge, crews, and capacity. Without foresight and planning, the coming solar boom could be overwhelming. If you exercise careful consideration, however, some incredible opportunities are coming down the line.

A Short Guide to Solar Panel Cleaning Machinery and Robotics

by Carla Dawson

In the United States, it is estimated that 1.1 billion solar panels will be going up in the next 8 years just for the commercial, industrial, and utility-scale segments. As solar installations grow worldwide so does the need for cleaning them. With the solar panel cleaning market continuing to expand, it’s a good time to learn about the machinery and robotics available to help you face each cleaning challenge with more success. Keep in mind, these guidelines are for the commercial, industrial, utilityscale segments only, not residential.

What is the ideal solar panel cleaning machine? That depends. The right machine is specific to the solar installations you have to clean, the resources available to clean it, and how your portfolio of cleaning jobs will be comprised. Most O&M, solar panel cleaning companies, EPC’s, etc. have a portfolio of solar installations. It is important to choose the machinery that will help you with all the installations in your portfolio. It

is also important to consider labor type (skilled vs unskilled), logistics, CAPEX, OPEX, accessibility issues, and more. What machinery allows you to clean each installation type efficiently?

Here are some important Concepts to Consider when analyzing the machinery and robotics:

Versatility

As your portfolio of solar installations grows and changes over time, will the machinery allow you to clean each new installation that is added?

Accessibility / Setup -

How easy or difficult is it to access the solar panels with the machinery you have chosen? Getting setup is a significant part of the job and generally speaking, the easier you can get set up the more productive you can be.

Rooftop

If the aerial lift cannot reach the solar panels, can you get the job done? If so, how?

Are the gaps between arrays an issue? How can you get the machinery from one array to the next?

Ground - Mount

Is the spacing between the arrays wide enough for the machinery or cleaning team?

Is there a drive shaft that impedes your access or complicates your operation? How far is the installation from where the cleaning crew lives/works?

If you need to clean a floating installation, what machinery will allow you to do the job safely?

Logistics

Logistics is part of Accessibility but it has to do more with getting the machinery to the site. Do you need a flatbed truck or can you get the machinery out to the site with a van or pickup truck and trailer? How do you unload the machinery and how many operators do you need to do this?

Worker Type

Do you need skilled workers or can unskilled workers do the job? Do you have labor shortage issues and is this going to impact your operations?

Power Source & Power Source Management

You need to power the machines and in some cases the water pumps and water treatment devices. How easy or difficult is it to keep the operation going?

Water Consumption

Solar panel cleaning should be done with treated water. How much water does your machinery use?

Productivity Levels

What does the average solar panel cleaning operation look like and what are your productivity levels? Go beyond panels per day. Understand the solar panel cleaning system and see how many operators are needed as well.

Machine Maintenance

How is the machine maintained? What are the parts that wear and tear? How much do they cost? What is the expected lifetime of the machinery? Does the local distributor have parts in stock?

Carbon Footprint

How are the machines powered? Are they carbon-based or clean energy?

System CapEx

Each machinery type requires a long list of complimentary items. Understand the solar panel cleaning system capital expenditure not just the cost of the machinery.

System OpEx

Each solar panel cleaning system has to be maintained. Look into these costs and frequency.

Commercial, Industrial and UtilityScale Solar Panel Cleaning Machinery

The guide below is not based on specific machines with specific brands but rather a generalized overview of each machinery type. There are significant differences between machine brands. The statements below are general guidelines.

Powered Lift and Shift Solar Panel

Cleaning Machinery

Powered Lift and Shift is a semiautomated solution that generally has the following characteristics.

Manual and Powered Water-Fed Pole

There are many manual and powered water-fed poles in the marketplace. Many residential cleaners use these tools when they win a C&I or utility-scale cleaning job due to the relatively low CAPEX.

Fixed Slider with Docking Station100% Dry cleaning

The solar-powered fixed slider with docking station is a system typically used where PV soiling rates are extremely high and the installation is very remote. Conceptually it is very different from the systems seen above because you have one robot per array that is fixed and housed in a docking station. The robot can be programmed to clean at a certain time or remotely activated.

The success of choosing the right machinery is directly correlated to your understanding of the cleaning challenges you have to face in the present and in the future. Analyze the characteristics of each of your installations and plan accordingly. Understanding the solar panel cleaning machinery options will help you make a better decision.

Cleaning Machinery

Brush & Lift / Tractor Brush is a semiautomated solution where a brush is attached to an aerial lift for rooftop installations or it is attached to a tractor or excavator for ground-mount installations.

Manual Lift and Shift

This system is powered by 1 or 2 people pushing the robot down an array. It is typically used in places where the labor rates are on the lower end.

Dry Cleaning

Solar Panel Cleaning Robotics

Solar panel cleaning robotics is a semi-automated solution that works for C&I and utility-scale installations.

Dry cleaning only is recommended in these parts of the world. All the systems above also function as dry cleaning options. Below are listed the solar panel cleaning machinery that is only dry cleaning.

The Unexpected Ways Changes to the Clean Water Act Impacts Solar Projects

by Robert Wilson, III

How the CWA affects solar

The Clean Water Act (CWA) is a key piece of legislation in the United States that governs how water bodies are managed. The CWA was first passed in 1972, and has been read additional info here on the EPA’s website. While many

Early changes to the CWA

In 2020, the Trump Administration’s EPA and Army Corps of Engineers clarified which waters were protected by federal jurisdiction on the Waters of the United States (WOTUS) in the Clean Water Act (CWA) with the Navigable Waters Protection Rule (NWPR). While maintaining protections for clean water, the 2020 rule preserved state authority over waters within their state and clearly defined what waters are subject to state and local protections vs. federal oversight. Further, NWPR clarified the ephemeral streams are not under jurisdiction of CWA and eliminated the nebulous “significant nexus” test to determine classification as WOTUS.

As is common in administration changes, the rule proposed by the Trump Administration was placed under review by the new Biden administration. In August 2021, the Arizona US District Court vacated the NWPR; all reviews are done using the pre-2015 regulations. Biden’s administration has proposed new changes that redefine WOTUS again, potentially broadening the types of waters to be protected.

Latest CWA changes impacting solar

The Biden Administration’s proposed changes to the definition of “WOTUS” would include those having “significant nexus” to waters of the United States (WOTUS, thus under federal jurisdiction). The concept of “significant nexus” is a key change, and implies bodies of water that connect.

This could classify waterways on private property (that only see water because of precipitation), streams, canals, dry riverbeds, and drainage basins as federal jurisdiction. Specifically, the proposed changes will focus on restoring protection to ephemeral streams, ditches, and adjacent wetlands.

The intended effect is to prioritize clean drinking water and keep the biospheres pristine. However, changing the definition of WOTUS by including those that share a “significant nexus” creates regulatory uncertainty on not just solar projects, but also other commercial development and even private property owners.

These new rules also expose solar projects to additional federal jurisdiction and oversight, which results in cumbersome and expensive permitting.

The following are three ways a developer can mitigate wetland impacts: Avoid, Avoid, Avoid! If you cannot avoid the water features, minimization is the best practice.

Staying within the thresholds of the Nation Wide Permits (NWP) is key to utilize NWP 51 and 57. NWP 51 has been specifically issued for renewable energy projects and has a 1/10 of an acre threshold. NWP57 is the replacement NWP for the revisions to NWP-12 for

line crossings and includes provisions for access roads. The NWPs have been reissued in 2021, so they are readily available for use by developers. The prerequisite is to file a Preconstruction Notification (PCN) with the local Corps office prior to any impacts.

3. Lastly, do not forget to consult with the local state office as well for compliance with section 401 of the CWA. State impacts are not always evaluated the same. States like New York have very stringent evaluation means and methods on what constitutes an impact.

The Clean Water Act (CWA) is a key piece of legislation in the United States that governs how water bodies are managed. It's been an important law for many years and has helped to protect our nation’s waterways from pollution, but recent changes proposed by the Biden administration will make permitting more challenging on solar projects.

Not only can these changes create regulatory uncertainty on solar projects, they also subject them to cumbersome and expensive permitting

requirements. This ambiguity adds renewable energy development uncertainty when it comes to dealing with private waters within state jurisdiction, or even just being near these types of waters at all.

In addition to thorough research and consultation with experienced hydrology experts, developers of projects over the next several years should stay abreast of challenges to the CWA as the Supreme Court (SCOTUS) agreed to take another look at the definition of WOTUS, granting Certiorari in Sackett, Michael, et ux. V. EPA, et al on January 24th

New York City’s Green Energy Future

by Michael Barry

In 2005, realizing that the climate crisis was worsening, then Mayor of London Ken Livingstone founded the C40, a global organization of mega-city mayors determined to create climate solutions of their own. In 2007, New York City’s Mayor Mike Bloomberg hosted a summit for C40 members; ever since then, New York City has been charting its own course toward sustainability and resiliency. While it may not be the first city you think about when the topic is green energy and sustainability, New York’s city government and a growing number of its residents, businesses, and organizations are determined to see that change.

Over the last several years, NYC has consistently ranked among the top American cities for renewable energy and innovative initiatives to facilitate a greener future. Current policies are moving the metropolis toward ever more ambitious green energy goals. One key piece of recent legislation, Local Law 97 (part of the city’s Climate Mobilization Act of 2019) features a plan to reign in a major source of emissions throughout the city: buildings. Surprisingly, the energy used by buildings accounts for nearly 80 percent of citywide emissions.

The new law mandates that most buildings over 25,000 square feet will be required to meet new energy efficiency and greenhouse gas emission limits by 2024, with the goal of reducing building emissions 40 percent by 2030. Although hard to imagine in a city dominated by skyscrapers, green roofs are appearing in all corners of the Big Apple. These roofs support vegetation that absorbs water, provides insulation, and reduce the heat island effect, a familiar phenomenon for anyone who has spent

an August in NYC. In addition, green roofs reduce stress on city sewer and wastewater management systems.

An extraordinary example of a green roof in action is atop the iconic Javits Center on the west side of Manhattan. This state-of-the-art, seven-acre roof absorbs up to seven million gallons of storm water run-off annually, and reduces heat gain throughout the enormous complex. Combined with other sustainable features, the center’s annual energy consumption has been reduced by 26 percent. The roof also hosts a one-acre farm that yields up to 40,000 pounds of produce annually and supports a vibrant community of wildlife.

Cities like New York have no shortage of distinct groups and factions vying for attention. Yet, most of the truly effective initiatives addressing climate change are cooperative in nature. It is not uncommon to see city government, commercial enterprises, nonprofits, and community leaders working together on projects to bring renewable energy to urban communities. In fact, it is almost impossible to create measurable change without this kind of cooperation across diverse groups.

For example, the Mayor’s Office of Climate and Sustainability houses a Clean Energy Communities program. The program is run by staff from local nonprofit Solar One and works in concert with state entities like the New York State Energy Research and Development Authority (NYSERDA), local communities, and energy businesses, including solar installers and grid operators. According to Elissa Knight, Director of the Clean Energy Communities

stakeholders,

in urban areas is difficult at best; there simply are not enough transmission lines to bring power to the city from upstate clean energy sources. But ambitious plans are moving ahead on different fronts all the time. Just last fall, then Mayor Bill DiBlasio announced plans for a $191 million investment in offshore wind turbines to help the city reach a goal of 100 percent clean electricity production by 2030, and full carbon neutrality by 2050. Of course, sustainability is not simply a matter of access to energy. New York City is comprised of five Boroughs— Manhattan, Queens, Brooklyn, the Bronx, and Staten Island—all of which have substantial coastlines. Manhattan is just a small island in the nexus of two major rivers, with a large natural harbor adjoining the Atlantic Ocean. Ten years after Hurricane Sandy flooded parts of all five Boroughs, the city is now beginning resiliency projects to protect the South Street Seaport and the east side of the island. Berms, seawalls, abundant vegetation, and green spaces are all part of the immense East Side Coastal Resiliency Project and the Financial District and Seaport Climate Resilience Master Plan.

New Yorkers increasingly understand that sustainability for the city is inextricably linked to environmental and economic justice. Dozens of organizations and activist groups are on the case, making sure that low-income communities are front and center in the city’s plans for a clean energy future. With access to a growing variety of clean and affordable energy sources, a forward thinking and diverse population, and the considerable weight of city and state government, New York City is moving quickly toward a complete transition to clean energy.

Michael Barry is the Communications Manager at Solar One, a NYC nonprofit delivering innovative education, training, and technical assistance that fosters sustainability and resiliency in diverse urban environments.

Program, “The investment and innovations in programs like these reflect New York City's consistent commitment to mitigating the effects of climate change. This is a community effort that involves participation from diverse stakeholders, and I’m pleased to say that collectively, we are moving the city towards a clean energy future for all New Yorkers.”

By their very nature, community power programs require cooperation between diverse groups, and it is in no small part these community wide efforts that are leading the charge toward sustainability. Marginalized communities are widely recognized as the most adversely impacted by climate change and can benefit most from access to clean energy. A growing selection of community power options enables residents, building managers, co-ops, and entire neighborhoods to choose to install solar power on their rooftops or subscribe to community power programs that supply energy generated by renewable sources. Despite impressive efforts, the city still receives close to 85 percent of its energy from fossil fuel sources. Siting and building clean energy installations

2021 Top Solar Contractor for Solar Power World: BAJA Carports

04 Enhance Listing

Mercedes-Benz of McKinney McKinney, Texas | 787 kW

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

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

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

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

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

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

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

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

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

It is clear a green energy transition is underway as electricity grids around the world install greater proportions of renewable energy generation. The electricity markets that operate on such grids are setting new renewable energy penetration level benchmarks year on year. Renewables have exceeded 50 percent of total demand in the UK at times, and have met total demand in portions of the Australian grid as far back as 2020. This trend is set to continue as Wind and Solar are now cost-competitive with traditional fossil-fuel generation sources. New fossil fuel plants are also facing challenges obtaining finance, and operating plants are being phased out early in many markets globally.

Wind farms, on the other hand, are increasingly viewed as a mature infrastructure class. Aside from the financial returns of a direct investment in or lending to a wind farm, the social capital afforded by renewable energy investments can be substantial. Further, Power Purchase Agreements (PPAs) are increasingly chosen by multi-national corporations to both obtain a hedge in volatile electricity price markets and show off their green credentials. The ability to state the amount of avoided carbon dioxide (CO2) emissions as a direct or indirect result of a company’s actions is a powerful marketing statement. It is also a tangible metric used to evaluate company sustainability targets, typically conveyed in Environmental, Social and Governance (ESG) reporting processes. ESG reporting principles have been adopted

by most banks and investment funds in order to increase transparency and build trust with investors/ consumers (while making returns).

When it comes to avoided CO2 emissions in the electricity sector, however, not all photons are created equal; production by each wind farm in a customer’s portfolio has a differing impact on climate change mitigation efforts. WHEN and WHERE a wind farm delivers power to the local grid has a large impact on the avoided CO2 emissions compared to fossil fuel generators.

emissions. The US Environmental Protection Agency’s (EPA) Emissions & Generation Resource Integrated Database (eGRID) determines total output average and non-baseload average emission intensity rates via a hindcast of the US electricity grid operations for yearly intervals. The total average emission intensity rates are calculated from all combustion generators contributing to the bid stack in the analysis interval. On the other hand, the non-baseload emission intensity rates are more comparable to marginal operational unit emissions intensity rates and can be used to roughly estimate emissions reductions by deploying renewable energy sources.

CO2 emission intensity rates of an electricity grid (typically expressed in kg/MWh or lb/MWh) are dependent on the generation fuel mix dispatched in each scheduling period. In un-regulated markets around the world like Australia (and some in the US, such as the Electricity Reliability Council of Texas or “ERCOT”), generators bid their available capacity at a unit price to meet forecast demand for each scheduling period. As operating costs for wind farms are low, they employ a bid strategy to ensure they are dispatched whenever the wind resource allows. Non-renewable generators must consider the fuel costs in their bid strategies. Therefore, the mix of generators (both fuel type and capacity) dispatched in each scheduling interval (i.e. the ‘bid-stack’) contains varying emissions intensities. The total emission intensity rate of each scheduling interval is therefore the weighted average of each generator deployed to meet requested capacity supply. Importantly, the generator that delivers the final portion of capacity supply in the scheduled interval is known as the marginal operational unit and it is this unit’s emissions (i.e. marginal emissions) that require consideration in avoided CO2 emissions calculations. For example, with decreased electricity demand (largely fossil fuel generators) in a scheduling interval due to higher penetrations of renewable energy or electricity customers employing energy efficiency measures, the capacity delivered by the marginal operational unit (and its associated marginal emissions) may correspondingly decrease.

Excellent resources are available to help wind farm owners and operators understand the positive impacts their assets are having on reducing greenhouse gas

The average rates are calculated at the plant level and aggregated to balancing authority and finally national levels. The eGRID data thus provide increased spatial resolution and an improved temporal precision by capturing changes in the electricity market in each analysis interval. Temporal precision is important; the total emission intensity rate reduced by 39 percent in ERCOT between 2004 and 2019. Reductions in average emissions intensity rates have occurred in most markets around the world.

However, the eGRID emissions intensity rates are not representative of the marginal operational unit. The EPA has developed another tool known as AVERT (AVoided Emissions and geneRation Tool) to allow users in the US to evaluate sustainability efforts via marginal emissions intensity rates. These rates provide spatial resolution and are representative for a temporal period in a similar fashion to the eGRID data.

For further temporal resolution and near-real time analysis, a physics-based time series method that identifies the marginal operational unit and evaluates its marginal emissions can be employed to more accurately capture the beneficial impact of deploying renewable energy and or reducing consumption compared to average emission intensity rates. By tracking company sustainability efforts of both consumers and producers of renewable energy, the time-series data can be incorporated into a wind farm secondary SCADA system to assist in ESG reporting processes. Correctly considering the spatial and temporal dependency of electricity grid marginal emissions intensity rates permit wind farm owners and operators to accurately document their contributions to reducing scope 2 GHG emissions.

Know the Warning Signs Understanding your wind turbine generator

by Nitin Kulkarni

Smart Application Engineering by detailed understanding of the operating conditions and function of the product is needed for many industries. It is especially critical for Wind Industry due to accessibility challenges up tower compared to typical industrial applications on the ground. But there are enough warning signs in most cases before the catastrophic failures or flashovers. Too often, these signs are either not understood or underestimated. Wind turbine generators are high-voltage machines; design or manufacturing faults and use of cheap products are common root causes of electrical failures. These products are not commodity. After install, the lack of preventive maintenance could result in severe damage, costly repairs, and unexpected shutdown of the wind turbine, all of which can be significantly minimized by applying better product and timely service by wind farm technicians.

The growth in wind as a major source of power is closely related to improved reliability of wind turbines. The rotation of the blades and shaft must include wear of the interacting parts and thereby concerns for maintenance and life of the related components. The wind turbine includes a wide variety of sliding electrical contacts to conduct electric power to and from the rotating parts. Along with generators and motors, some other systems also include grounding and lightning protection. Majority of these electrical systems include the sliding contact, commonly called a carbon brush, the brush holders with spring, and the rotating collector rings. The wear at the sliding contact interface can be a limiting factor with reduced reliability, and more frequent high-cost maintenance cycles.

A carbon brush is subject to wear from both friction and from electrical erosion. The objective is to attain a balance between these factors for a minimal total wear rate of the interacting sliding surfaces. Optimal designs and appropriate preventive maintenance service can offer impressive results with minimal planned downtime and reduced operating costs, but it takes some effort.

Following are significant elements for continually improving the function of the carbon brushes in a wind turbine.

1. Wind turbine generators are complex devices. Manufacturers have typically outsourced the carbon brush holder assembly. The add-on of the slip rings, brush holders, and carbon brushes should provide a well-coordinated system. However, these components are most often manufactured, and sometimes designed, in various locations and by different companies. As a result, the quality, reliability, and compatibility of these parts can be deficient. Turbines that are re-powered for higher output require optimum product selection, as operational parameters change. The proactive design coordination of the carbon brushes, brush holders, and collector rings according to the operating conditions is vital for superior performance and life.

2. The growth in wind as a major source of power is closely related to improved reliability of wind turbines. Specific operating conditions can significantly affect the reactions at the carbon brush contact. Operating with generator output either above or far below the machine rating will cause

faster wear. Contaminated atmosphere (including marine environments) can cause the ring surface to have higher resistance and higher friction. Installations subject to freezing temperatures have air with low moisture content (low relative humidity) that can cause higher frictional wear of the carbon brushes. In these cases, adjustments in the brush grade may be needed to approach normal performance and life of the sliding contact system.

3. The spring force on the carbon brushes is a crucial factor for proper function of the sliding contact system. The pressure must be appropriate for the expected amperage levels and the sliding speed. This means the spring must provide enough pressure to assure a reliable electrical connection, yet not too much pressure to cause excess frictional wear (image 1). Just like carbon brushes, the springs are often taken for granted, and may also need replacement. The force on springs will decline over time, so regular checks on springs is needed to avoid increasing wear.

4. Unlike most electrical components that suddenly fail, the carbon brush holder assembly will show symptoms of deterioration well before total failure (image 2). Regularly inspecting used parts can be a powerful diagnostic tool. With regular observation and trending of the filming/patina condition, arcing, heat, and the worn carbon brushes, deteriorating conditions can be identified and corrective action can be taken to address the problems, thus avoiding the threat of an unplanned shutdown. The carbon brush holder assembly is a critical yet often misunderstood part in the operation of the wind turbine. Excess conductive dust from wear of the carbon brushes (image 3), swelling of the carbon brushes (image 4), and grooving or threading of the slip rings (image 5) are especially frustrating and expensive fixes. The motivation to avoid such frustration and cost is exaggerated by the inconvenience of the up-tower location.

There is always an opportunity for improvement by first understanding the symptoms and then fixing it. Predictive and preventive maintenance is the KEY to success. Show your used carbon brushes, springs, and holders to subject matter experts to learn the warning symptoms. With many turbines going out of warranty, look for improvement for life expectancy and reduction in long term maintenance cost. Be flexible for engineering trials with constant monitoring. With information on the existing design, data on the operating conditions, and observation of trends toward undesirable symptoms, adjustments in the sliding electrical contact system can attain excellent results. (image 6) The reward for satisfactory wind generator operation is significant and it is certainly worth the time investment!

How Remote Monitoring Can Increase Reliability

by Michael Dietl and Dr. Edwin Becker

Figure 1: Bearing damage is one of the most common wind turbine problems. Historically, roller bearings cause the most frequent problems.

Using wired sensors for condition monitoring of wind turbine machinery and components isn’t new. However, continuous advancements in technology and connectivity powered by the Industrial Internet of Things let maintenance professionals strategically maximize historical and real-time data remotely, increasing wind turbine reliability and availability.

Today, operators can more easily get ahead of common wind turbine problems. Using years of cumulative wind up-tower and down-tower data, analysis experts can more accurately predict machine problems, such as bearing wear or damage, to prevent machine failure.

Growth of remote condition monitoring services

According to the U.S. Department of Energy’s 2021 Wind Market Report, U.S. wind capacity reached a record 16,836 MW in 2020, for a total of 121,955 MW, and overtook solar power installations for the first time in many years. In 2021, China, the U.S., Germany, and India had the highest increase in wind capacity. Because of the technological advancements in wind turbines and the increase in wind turbine installations globally, the demand for and value of remote condition monitoring systems continues to grow. This is especially true for vibration monitoring.

In 2015, the average age of a North American wind fleet was 5.5 years. In 2020, the average age was estimated to be seven years old, and fourteen years old by 2030. As a result, optimizing wind turbine performance to ensure regulatory compliance and life expectancy is critical, as is finding the most efficient ways to keep maintenance and operations costs down.

Many maintenance teams lack the specialized condition monitoring and data analysis expertise to monitor an entire fleet constantly. That pushes organizations to enlist an external remote condition monitoring service to help wind farm operations decrease vibrations and up-tower maintenance — reducing operations and maintenance expenses. Additionally, costs can be further reduced by adopting condition-based maintenance (CBM), a subset of predictive maintenance strategies wherein only relevant maintenance is performed based on machinery data and health.

Figure 3: Powerful software provides insightful asset condition monitoring data enabling deep analysis.

Benefits of a remote condition monitoring service:

• Improves maintenance planning and scheduling

• Prevents unscheduled and costly downtime

• Extends equipment lifespan

• Reduces maintenance and production costs

Wind turbine remote condition monitoring services fill maintenance operations gaps

A lack of resources and on-premises data analysis experts often drives the need for partnering with an independent remote condition monitoring services company.

Remote condition monitoring service companies continuously monitor wind turbine vibration data and provide expert analytical evaluations.

Some operations offer a complete solution beyond services that include hardware and software. This allencompassing service model enhances a more cohesive relationship between providers and customers.

Because wind fields are often in remote locations, information about a machine issue must be communicated quickly. Expediency is even more critical if the wind turbine is located offshore and has weather concerns.

Fault diagnosis expertise is necessary for identifying the type and location of the fault and determining the severity of the fault and time to failure. With a data-driven remote condition monitoring service, customers know which component is causing a problem and why. The provider’s experts make recommendations on fixing the problem based on condition monitoring data, and they offer advice on targeted vibration reduction.

Choosing a remote condition monitoring services provider

The extent of services a provider offers varies depending on their capabilities and experience. A remote condition monitoring service should include recurring analysis and reporting, status reports at periodic intervals, event-driven reports, and data management. Also, data should be accessible from anywhere, and the system should include a robust software system. Ultimately, it should be apparent that

Figure 2: A wired advanced vibration analysis tool can measure and monitor a wind turbine’s main bearing, gearbox, generator, and nacelle. This graphic details vibration velocity levels according to VDI 3834 and ISO 10816-21 standards for component-specific frequency ranges, acceptable (green) and unacceptable (red).

the remote condition monitoring services provider possesses product, application, and industry expertise.

Five things to consider when choosing a remote condition monitoring services provider

1. Monitoring & diagnosis certifications matter

The remote condition monitoring center should be certified and offer FMEA-based states diagnosis (Failure Mode and Effect Analysis). Ensure those performing your data monitoring and diagnosis are ISO CAT certified, i.e., monitoring specialists with ISO CAT I certification. Diagnosis specialists with ICO CAT II, III, and possibly ISO CAT IV certification.

2. Impartial independent remote CM providers

The original equipment manufacturer (OEM) often provides remote condition monitoring services to its buyers. However, there can be drawbacks to using an OEM. When you partner with an independent services provider, you receive a fresh view

of the machinery without preconceived notions about why a component experienced a fault. Their assessment of the machine’s health is based on data.

3. Expertise and hands-on experience counts

When it comes to wind tower data diagnostics and analysis, the more experience your service provider has, the better. Look for a provider with a track record for solving wind turbine problems and one that understands the complexities of vibration analysis and fault diagnoses. Make sure the service provider can show you years of proven expertise, knows wind turbine machinery inside and out, and that they understand your organization’s needs and goals.

4. Consider a full-service solution and partner

A complete remote condition monitoring vibration system should include the hardware, as well as software and services. Your provider should be an integral part of your operations and someone you trust fully to keep your equipment up and running. If your company plans to expand its condition monitoring program in the future, look under the hood of the company you choose. Are they on top of technology? Will their devices integrate with others? They should be able to tell you how their service fits into your reliability journey now and into the future.

Increase cost efficiency

There are a variety of ways that remote condition monitoring can help ensure a high return on your investment. One of the most obvious cost efficiencies from condition monitoring comes as wireless sensors reduce the need for route-based maintenance. A services provider should be able to offer different service levels to fit your needs and budget.

Improving the Performance and Reliability of Wind Turbines

by Ryan Greenfield

Inside today’s high-performance wind turbines, where the locating bearing is subjected to particularly high loads, the rotor shaft bearing support is a vital component. These unique application conditions, combined with stringent reliability requirements and increasing incidents of failed bearings in the field, provided the impetus to optimize the spherical roller bearings that are used as wind turbine main shaft bearings.

This research resulted in the Asymmetric Spherical Roller Bearing (ASRB), which offers high wear resistance as well as considerably lower friction torque and operating temperatures than the conventional standard. As such, this innovation has the potential to significantly extend wind turbine reliability and operating performance.

The Challenge

The main shaft inside a wind turbine supports the main rotor hub and transmits rotational energy, in the form of torque, from the rotor hub to the gearbox. This application requires high reliability as well as robust resistance to the high loads generated by the rotor blades. Due to the high levels of thrust generated in this environment (see Fig. 1), conventional double-row symmetrical spherical roller main shaft support bearings used inside wind turbines experience uneven internal load distribution between the roller rows. This causes the rotor-side row to have lower load, while the gearbox-side row is potentially overloaded. Because of the low speed of the rotor shaft, only a minimal grease lubrication film is generated. This, in turn, produces a metal-to-metal running condition. The result: a high rate of surface wear, poor performance and, ultimately, premature bearing failure.

Following an extensive investigation of failed bearings, based on data obtained by analyzing the performance of approximately 10,000 wind turbines located throughout the world, it was noted that a significant percentage of failures occurred mostly in locating bearings of the 3-point as well as 4-point support rotor shaft systems. Both of these shaft systems are fitted with standard spherical roller bearings designs that feature two rows of symmetrical barrel rollers. Most of the damage was found to be concentrated internally on the axially loaded row (downwind) of the locating bearings. The damage, observed primarily at the surface level, is classified in accordance with ISO15243 as either fatigue occurring near the surface (surface distress) or abrasive wear.

As noted above, abrasive wear in wind turbine main bearings operating under random conditions is already a widely recognized problem. This type of damage is primarily caused by varying shaft speed and loads that can lead to a very thin or nonexistent lubricating film. If the separating lubricant film between the roller and raceways surfaces is allowed to degrade, micropitting, smearing and, eventually, extensive damage (spalling) at surface levels will be the result.

Optimizing the Existing Standard

The first step in addressing these issues was to develop and validate a lubricant formulated with the proper load-carrying properties for a variety of operating conditions, including low shaft speeds and extreme loads. Beyond merely improving the lubrication conditions, however, a strong emphasis was placed on optimizing the design of existing standard bearings with enhancements, such as extremely strict surface finish limits and special coatings on the rollers.

Figure 2: Comparing wear on uncoated vs. coated rolling elements

To that end, a metal-containing hydrogenous amorphous carbon coating optimized the standard bearing design by offering a high level of protection against abrasive and adhesive wear (see Fig. 2). Due to its highly ductile coating structure, this coating can withstand the high contact pressures that routinely occur

Figure 3: Coated bearing rolling element

Figure 1: Rotor shaft bearings are subjected to a range of dynamic loads, especially high axial loads

in rolling bearing applications. As a result, the coated rollers significantly reduce sliding friction and minimize sliding-induced damage. To further mitigate the potential for sliding, these upgraded bearings utilize a two-piece brass cage that enables each roller row to rotate independently.

The Ultimate Solution

Beyond merely optimizing the conventional bearing design currently used in most wind turbines, however, the goal was to provide a bearing solution that would be able to perform under high-thrust loads while still maintaining its excellent misalignment characteristics. To that end, an entirely new bearing design for main shaft bearings in wind turbines was created: the asymmetric spherical roller bearing. The term “asymmetric” refers to the bearing’s different contact angles, which serve to improve the load distribution between both bearing rows, reduce the contact pressure and friction torque, and increase axial stiffness by approximately 50 percent. Moreover, this unique design prevents rollerto-raceway contact stress peaks from developing as a result of the periodic bending of the rotor shaft during operation, or accuracy errors that arise from the initial assembly inside the wind turbine’s nacelle.

The operating principle behind the asymmetric spherical roller bearing is as follows: While the rotor side of the bearing is designed to carry the normal radial load present in the application, the gearbox side of the bearing is optimized with an increased contact angle to accommodate the high thrust. During operation, the potentially damaging thrust is safely transferred through the bearing and transmitted to the housing support (see Fig. 4).

The innovative asymmetric design ensures a more even internal load distribution, which provides improved

rolling motion while minimizing sliding. The result: less torque, less friction and less heat. Plus, the axial displacement of the bearing is also reduced.

Can Offshore Wind Actually Compete?

by Neal Dikeman

Offshore wind is a growing and increasingly hot area for renewable energy developers and policy makers.

But today, the levelized cost of electricity (LCOE) and project time to develop, offshore wind in its best markets remains significantly disadvantaged compared to onshore wind and solar in their best markets. Onshore wind and solar technologies now have lower LCOE than even the marginal cost of just the fuel in a fossil power plant in many markets. The big question remains: Is offshore wind a massive niche and policy boondoggle, or can it be as competitive globally as its onshore cousins?

Laying Out the Case For Competitiveness

Regional Policy and Economics: Cleantech and energy may be global, but power is regional. The story of cleantech growth has been one of the hyper-regional growth stories; good news is offshore wind probably doesn’t have to beat onshore — it just has to beat it in its best markets as the marginal resource (or see public policy support it).

Resource Wins: The best high-quality renewable resource at scale outside of hydro is offshore wind. A little longer turbine is not just a little better in wind turbines — it’s exponentially better when placed in the best resource. In energy, the best and biggest resource tends to win. So offshore will eventually outcompete all other resources.

Easy Technical Problem: This may sound odd, but offshore wind is a technically easy. Yes, it is expensive, capital intensive, and massive, but the technical challenges of scaling systems of this type are well known, even offshore. We built 50,000-ton ships almost 100 years ago, and can build ships ten times that large today. We were drilling offshore in 1897, and now drill in twomile deep water. That’s technically hard. With due respect to the engineering industry, offshore wind is in the category of “First Sergeant, get it done.”

Early Days on Scale: The industry is still really small, whichmay seem strange to say for a decade-plus old sector with GWs of production, but a Gigawatt is nothing in energy. The story of cleantech and renewables is one of mass manufacturing scale-up dominating technical advances to drive down costs, which we haven’t yet seen in offshore wind. Hence, the best is probably yet to come on costs as it grows.

Not Entirely Cut and Dried: The Challenges

Complexity and low Volume is the Enemy in Cleantech – Most of the world's scale successes in cleantech in the last fifteen years (e.g., Solar, EVs, Batteries) were due to mass manufacturing. These advantages were delivered from high volume manufacturing, productization, rapid deployment, and repeatability to drive costs down through volume practices. Even at a massive scale, we with offshore wind we are still talking about largesized, relatively low volume units from a handful of companies--not the kinds of factory built things that lend themselves to the type of mass manufacturing scale and competition that have been winning in cleantech. For offshore wind the industry may find that a fatal flaw to keep up with cost reductions in other sectors, and we may never see the prices come down comparatively.

Industry Not Built for Success – The marine, drilling, and oil and gas industries all have the technical skills set to deliver offshore wind – and have for decades. But the marine and offshore industries have been designed to provide complexity and safety in large, complex, long lead time custom projects. Ultra-low cost, repeatability, cost down manufacturing like the successes in onshore wind, energy storage, and solar PV would be an entirely different framework for the industry. If it succeeds, it will likely have to change its stripes and adopt an entirely new DNA.

Competing with Falling PV and Onshore Wind Costs – Chasing PV and onshore wind is kind of like catching a falling knife, and industry cost curves underlying solar cells

and battery continue to drop. My firm sees no reason why we can’t reach $0.01/kwh wholesale power. Few analysts are advocating offshore wind can match that cost curve – but perhaps in some markets that’s ok.

Electric Infrastructure Costs: In the utility-scale renewable projects that now dominate the US and global electric power capacity additions each year, the dominant variable to both economic success and project delivery is usually available transmission infrastructure. That does not exist offshore and is a LOT more expensive to build there, leaving it.

I’ll leave you with an analogy from history. Over a decade ago, I visited a fabrication yard in Scotland. The yard was one of the first movers in offshore wind platform fabrications, founded to make offshore jackets for the North Sea oil industry, and the last jacket had been completed.

For offshore oil, the company would design and assemble one massive customengineered jacket every 18 months. The offshore wind industry did not need custom one-offs and couldn’t afford the cost of them. For wind, the team needed to roll three jackets a week into the water for a year – for one small 150 MW wind farm. Nobody in the marine industry had done that since the US Liberty Ships in World War II: 2,751 Liberty Ships were built, with the first one taking 150 days, and the fastest taking four days and fifteen hours to complete.

Wind turbines are no more complex than a Liberty Ship, and the US had to invent every process to build them from scratch. If the offshore wind industry decides to build like Liberty Ships, there won’t be much to catch it.

Positive Wind Trends Continue for 2022

by Vikash Patel

While mindful of challenging events that continue to unfold around the world, the wind energy industry can celebrate a record-breaking year in 2021. Trends for 2022 point toward continued growth in many facets of the industry. Wind energy is being embraced by government and utility sector leaders who continue to set optimistic goals for renewables. These tailwinds will power the industry as it works through regulatory, labor, logistics and site selection challenges.

There was more wind, solar, and energy storage installed in the United States in 2021 than any previous year, according to the American Clean Power Association. More than 7.2 gigawatts of new wind capacity were installed through the third quarter of 2021 (enough to power nearly 2.2 million homes). That comes out to nearly 1 GW more than what was installed through the third quarter of 2020, and nearly double the wind capacity installed during the same period in 2019.

For 2022, the project pipeline remains busy, although last year’s record pace may be hard to match. Much of the low-hanging fruit has been achieved in site selection of land-based projects. Longer and/or more expensive permitting and development processes could be in store at more challenging locations.

There also could be a downtick in installed projects due to congressional delays in extending the production tax credit. The credit of $18 per MW expired at the end of 2021. The U.S. Department of Energy reports that the current PTC, along with improvements in the cost and performance of wind power technologies, is helping to drive project demand.

Other actions by government could boost the industry long-term. In January, it was announced the Interior Department would hold an offshore wind lease sale of the most lease areas ever offered, in the New York Bight off the coasts of New York and New Jersey. The resulting projects could generate up to 7 GW. Earlier, the Biden administration announced a goal to deploy 30 GW of offshore wind in the United States by 2030.

State governments have set wind energy targets as well. New York plans to invest $500 million in offshore wind energy, and is seeking an offshore grid that can deliver 6 GW to New York City. North Carolina set offshore wind development goals of 2.8 GW by 2030, and 8 GW by 2040.

On the corporate side, an $8 billion, 2.6 GW wind farm is planned off Hampton Roads in Virginia by 2027; another is eyeing a 2030 completion goal for 2.5 GW off the coast of the Outer Banks in North Carolina. Corporate customers are creating demand for renewables through their own sustainability goals, and the environmental, social, and governance movement among shareholders will further this trend. Meanwhile, jobsites can expect to cope with the ongoing pandemic as they enter a third year of facing negatively impacted labor and logistics, including temporary labor issues due to employees testing positive. Safety protocols for

subcontractors will see constant evaluation and evolution. Clusters of positive tests in manufacturing and logistics could continue to create supply chain issues that ripple their way to jobsites. But with fewer government-mandated lockdowns and with backlogs at U.S. ports slowly shrinking, supply chain bumps should level out.

A long-term trend that will impact the supply chain is the onset of wind energy component manufacturing on American shores. The first offshore wind turbine OEM blade facility in the United States is scheduled for construction (currently, these parts are imported from Europe). The $200 million facility in Portsmouth, Virginia, is intended to support the Outer Banks project. OEMs tend to attract suppliers, so the announcement of this facility could trigger the buildout of a domestic manufacturing supply chain.

Project scale is also expected to continue growth trends, both in hub height and blade lengths. DOE estimates the average land-based hub height was nearly 300 feet in 2020, a 59 percent increase since 1998. Offshore hub heights that averaged 330 feet in 2016, are predicted to rise to 500 feet by 2035. Rotor diameters have grown more than fivefold over the past two decades, and averaged 125 meters in 2020. Manufacturers are working on turbine models with 200-plus-meter diameters.

Bigger, taller turbines can generate more power. More power brings up the issue of storage. In fact, several companies are trying to innovate in this space. Various concepts include undersea reservoirs that turn excess wind into hydro power, and 220 MW floating boat-batteries that can carry offshore wind energy back to land.

The pandemic has created untold hardship for millions around the world. Science, government and business have been forced to learn on the fly. Despite all of this, the wind energy industry has been able to maintain momentum. While there will continue to be new challenges, the outlook for wind energy is bright in 2022, and for the years to come.

Responding to the disruptions of the COVID-19 pandemic, leaders are looking at all options to help build companies (and cultures), maximize efficiencies, and determine the best path forward for teams that have experienced the benefits (and sometimes the difficulties) of lockdown-driven “work from home” policies.

The result? Companies that have permanently embraced remote work.

Many of these companies will continue to maintain an office where employees are welcome to work, if they choose. Some label this a hybrid system, but there’s a risk that this approach can inadvertently create “classes” of employees with those who work remotely becoming less “seen”—and therefore less valued—than those at the office. To avoid this inequity, one solution is to view every employee as a remote worker all the time.

Especially for software companies, a remote-first policy can be seen as analogous to mobile-first web applications: the app is developed to work perfectly on mobile devices but also possesses the ability to gracefully fall back to working well on desktop devices. In much the same way, companies are creating a platform that trusts their employees to make the best decisions on where to work.

A lot can be learned from initial adopters. Following are some experiences and best practices of those who jumped in early.

Making Remote-First Work Sustainable: The Leaders

Pandemic lockdowns made clear the immediate productivity benefits of remote work. As lockdowns began, it became important to look closely at the advantages and disadvantages of remote, especially measuring the savings and a robust hiring pool with the isolation and potential for a lack of boundaries that come with working remotely. Getting a scope of the complexity of the issue is a great first step to establishing your own policies.

Remote work can provide unique insights into working with others by meeting your teammates on their terms, in their environments. You can save yourself a lot of trouble by establishing ground rules that emphasize flexibility (hours and locations), recorded knowledge, universal and easy access to documentation, asynchronous communications, and results. Among many valuable lessons learned is that through remote work you can learn more about your team faster than you ever might in a quick conference room discussion.

How teams socialize and work together are often vastly different. A successful transition requires a company to view asynchronous work not as a pandemic-driven fad but as the future—and a competitive advantage in the market. One challenge is balancing team camaraderie with an organizational culture that can satisfy and develop key performance indicators (KPIs).

Ultimately, remote-first work helps create a more sustainable future. Greenhouse gas emissions are reduced when commutes are eliminated, and carbon footprints are smaller in a home-office setting versus commercial and industrial spaces that must use more energy to maintain constant lighting and climate control. Also, less paper and plastic are consumed.

Strong Relationships and Asynchronous Work

The key to implementing a successful transition to asynchronous work is communication. Prepare everyone by conducting a survey of your team to find out what they need to move forward; this will help make the shift to remote-first work a largely positive experience. Overall, employees tend to report a better work-life balance and improved communication compared to when everyone commuted to the office every day. As with any bold initiative, there will be growing pains; consider establishing a group of volunteers who will work to help resolve emerging issues and develop recommendations for the path forward.

Relationships will benefit from minimizing meetings and maximizing connections through more intentional strategies. Examples include a weekly (and random) pairing with a fellow employee just to chat and get to know each other, and non-work-focused Slack channels.

Scheduled meetings will often be asynchronous. To empower team members, look for a clear agenda, expected action items, and enough advance time so participants can respond across time zones and their life responsibilities. And to reduce distractions, aim for a clear expression of deadlines. Some things need to be resolved immediately, but the “urgent” label is used too often. To ensure teams focus on the correct priorities, use detailed documentation of all processes; include a verification process by which the original author is periodically prompted to “verify” that documentation is up-to-date so all users benefit from the latest information.

Embracing and Optimizing Remote-First Work

Be realistic. You will not solve all the remote-first challenges; it’s an iterative process. For a variety of reasons, some candidates can’t relocate, while current team members who must move (e.g., a spouse/ partner starting graduate school in another location) don’t have to leave the company. To make a successful transition to remote work, company leadership must be fully on board and leading the charge.
