Less than six months after it was signed into law, the Inflation Reduction Act (IRA) has already spurred over 100,000 clean energy and climaterelated jobs in the U.S., with a total 9 million jobs anticipated to be created over the next decade. In fact, it is estimated that 99 percent of people who will be working in climate industries by 2030 haven’t yet begun. But what types of companies are seeing the most growth, and which jobs are currently highest in demand? We spoke with Catherine McLean; as CEO and Founder of clean energy and sustainability recruitment firm, Dylan Green, Catherine lives and breathes these jobs on a day to day basis. Test your knowledge, and see if you can guess her answers to the following questions.

1. What types of climate and clean energy jobs are most in demand these days?

a. Sales, marketing, and communications

b. Project origination, finance, and development

c. Engineering and IT

d. Operations

Catherine: “Project origination, finance, and development jobs are by far the most in demand that I’ve seen, particularly among utility-scale solar and storage and electric vehicle (EV) companies. The reason for this is that there is a lot of capital being invested into these kinds of projects at the moment. There are a ton of applicants who work in marketing and communications, but I’m actually seeing the least demand for these types of roles currently. While my clients previously had a decent amount of marketing jobs open about a year ago, these have really slowed down in recent months.”

2. What types of clean energy companies are hiring more?

a. Wind energy

b. Energy efficiency

c. Solar and storage

d. EVs

Catherine: “All of the above, but I’m seeing a huge increase among larger solar and storage companies, as well as EV companies. I would also add that sustainability job openings have been increasing at a similar rate to EV job openings. A year ago, I wasn’t filling any roles with EV companies or organizations looking to start or develop their sustainability departments. Today, it’s a different story.”

3. How often are clean energy companies hiring candidates from outside the industry?

a. <10% of the time

b. <25% of the time

c. 50% of the time

d. >50% of the time

Catherine: “Clean energy employers are still quite interested in only hiring applicants who already have clean energy experience, so my answer to this is less than 10% of the time. However, cleantech is hiring 5x more from other industries compared to the oil and gas industry, which hires almost exclusively from within. This is partially due to the fact that the oil and gas industry is hiring less in general compared to the renewables industry. I have also been increasingly able to show clean energy employers the value of hiring candidates from outside the industry. In fact, last year I was able to double the number of non-clean energy industry candidates I placed compared to the year prior. If our industry is to scale in a short amount of time, we absolutely need to hire and learn from candidates with transferable skills who come from more developed industries.”

Clean Energy Job Growth

What you need to know

4. Which of the following backgrounds/experiences are clean energy employers interested in?

a. Legal

b. Real estate

c. Policy

d. Finance

Catherine: “Hands down, clean energy companies, especially utility-scale solar and storage companies, are looking for applicants with a background in real estate. This is due to the fact that their skills are very easily transferable. For example, someone who works in solar project development can leverage the similar financing, permitting, and legal structures that non-solar real estate projects utilize. Other than real estate, I have been able to source and place candidates in clean energy who came from industries such as legal and finance, to name a few.”

5. What percentage of employers are looking for more women, BIPOC, LGBTQ, or people with other marginalized identities?

a. <10% of the time

b. <25% of the time

c. 50% of the time

d. >50% of the time

Catherine: “My clients are requesting more diverse candidates the vast majority of the time, as employers are well aware of the benefits of hiring and retaining staff from a wide range of backgrounds - including over 25 percent greater company profitability. This is great news, as it’s essential that we prioritize diversity as our industry rapidly expands - both because it’s the right thing to do, as well as because it has been proven to enable greater innovation.”

6. What percentage of the time are clean energy employers open to remote work?

a. <10% of the time

b. <25% of the time

c. 50% of the time

d. >50% of the time

Catherine: “Employers still prefer staff to work in person, however, they are much more flexible about this due to getting used to staff working remotely as a result of COVID. Hybrid roles are the most common type of role that I’m currently seeing. So while employers prefer staff work remotely 0-10 percent of the time, they are open to 40-60 percent in office versus remote work, particularly if they are highly interested in a candidate. Some employers do agree to fully remote candidates if they are the top choice for the role.”

7. Are clean energy companies interviewing more or less than they were a year ago?

a. More

b. Less

Catherine: “Ironically, despite the fact that there is significantly higher demand for new clean energy jobs, employers across the board are investing far less time interviewing candidates. That is because they are getting burned out in this market, where the supply of candidates is still low relative to the high demand for skilled workers. Employers are increasingly using recruitment firms to do the heavy lifting of searching for and vetting candidates for them. That way they only have to spend time interviewing a few they are really interested in. Employers are, therefore, also moving much more quickly from interviewing to hiring.”

Mobilizing to Win

The United States is slow to anger, but relentlessly seeks victory once it enters a struggle, throwing all its resources into the conflict. “When we go to war, we should have a purpose that our people understand and support,” as former Secretary of State Colin

While the language and tone in the debate about climate change is too often likened to a “war” and “combating” the challenge, the reality is that changing climates around the world present a real risk that needs to be addressed with seriousness and practical solutions as we innovate towards the future. We know from experience that American leadership on stewardship and innovation will make the world a healthier and more prosperous place – free economies are clean economies by twice as much. What we need is not a “war” on carbon, or even to “combat” climate change, but rather to accelerate innovation across all solutions with cleaner gas, captured, stored, and recycled carbon, advanced nuclear energy, geothermal, hydro, wind and yes, solar.

The sun is the source of virtually all of the energy on Earth. Even the energy released when we burn fossil fuels such as oil and natural gas is energy that originally came from the sun, during Earth’s Mesozoic Era.

Where there are deserts or other sparsely populated places with plenty of direct sunlight, we should be placing solar arrays. The same holds true for turbines. Where there are few people but plenty of wind (such as north Texas or the Oklahoma panhandle) there should be windmills. We should then run DC wires to deliver the electricity efficiently to as many cities as possible. We live in an amazing era of innovation and creativity. Renewable energy is making incredible strides in cost reduction and deployment, especially in recent years. Yet, wind and solar only make up a relatively small percentage of American

electricity generation, providing 12 percent of the nation’s power generation in 2021 (wind at 9.2 percent, and solar at 2.8 percent). There is plenty of room to grow; we need to push those numbers up as quickly as possible.

One way is to deploy flexible solar arrays, which can be scaled up as necessary and moved if needed. These portable solar panels can be installed almost anywhere. Plus, some of the latest solar installations can be made with recycled material and are fully recyclable — after they have served their useful lives, they can be repurposed, rather than being tossed into a landfill.

Another way to accelerate the deployment of more solar energy would be to remove all government subsidies for mature energy technologies. This includes the ITC for solar. As the CEO of a solar company, I know it’s not a popular position, but I’ve seen firsthand how tax credits add time, complexity, legal cost, and even project costs when developers (and those with tax “appetite”) are more focused on tax credits than being cost competitive. What we need is a level playing field, without the government picking winners. This is a massive market, with ample investment opportunities and significant market demand. We don’t need government subsidies for technologies that are already mature and in the market.

The Business Council for Sustainable Energy reports that: “[t] he injection of $105 billion in new private capital in the U.S. energy transition in 2021 is an 11 percent year-on-year increase, and a 70 percent increase over the past five years. The 2021 total included $47 billion in renewable energy (45 percent), $35 billion in electrified transport (34 percent) and a doubling of hydrogen investments to $200 million in 2021.” Globally, the total investment in these energy sources and technologies was $755 billion in 2021.

Meanwhile, the U.S. needs to continue to lead the world in the development of battery technology. We also need to build redundancy into the system as much as possible; if one source of energy isn’t available, we need to be able to move smoothly, without interruption, to another source.

All-of-the-above also includes nuclear energy, of course. Nuclear runs practically non-stop, providing an abundance of carbon-free energy. The latest Small Modular Reactors are safer and easier to build than traditional nuclear power plants.

It’s time for the world to have an intellectually honest and evidence-based discussion about climate change and how to

best address it. We don’t need a war on climate change. What we need is to accelerate energy innovation to be increasingly clean, efficient, reliable, and affordable. Let’s find solutions that can adapt to challenging and changing climates wherever they present themselves. In the end, it’s those solutions that will help lift people out poverty, and provide for a safer, more peaceful, and prosperous world.

Pushing Boundaries

Are operations vessels ready for floating wind farms?

The possibilities for offshore wind feel vast. Last year, the Biden Administration announced that the target for the growing U.S. offshore wind industry is 30GW of power by 2030. One of the driving forces behind this increased appetite for offshore is the innovation of floating offshore wind structures. The stated goal in the US is for almost half of all offshore wind assets to be floating.

It is one thing to lay down promising targets. It is another to plan and, where necessary, improve current infrastructure so that it is up to spec to make these dreams a reality.

As climate change continues to disrupt traditional weather patterns, the conditions offshore have grown increasingly unpredictable and, in some cases, difficult to contend with. Main effects on the maritime industry include:

• Increased frequency of storms, raising the possibility that operations will be delayed or postponed

• Increased severity of storms that make routes impassable

• Rise in sea temperatures reducing ocean salinity, impacting the stability of ships, and prompting re-design

Amid the rapid roll-out of offshore wind, developers need to address whether there are sufficient vessel options that are cost-effective, environmentally friendly, and provide comfortable working conditions for the crew. Now is the time to assess how legacy designs can be modernized to better endure severe offshore conditions.

The importance of comfort

Practicality should not overlook the need for high-quality working conditions for technicians. Understandably, seasickness is the most frequent health and safety consideration for asset-operators. Not only does the prospect of experiencing seasickness in difficult conditions make offshore wind engineering less appealing – a problem for the industry given the skill shortage – but it inhibits the possibility of engineers doing their best work.

In short, sub-optimal workboats produce sub-optimal work.

Installing hydrofoils on smaller vessels help suppress motion and vibration, which goes a long way towards reducing the impact of seasickness. As ocean salinity reduces, the need for technologies that improve ship stability in severe conditions is critical for making workboats more desirable and effective working environments. Since engineers are sometimes compelled to spend days at sea, travelling to offshore sites in increasingly harsh conditions, it would be an industry oversight not to match expectations of a 21st century workplace with appropriate upgrades and improvements to worker comfort.

Cost-efficiency, decarbonization, and vessel options for O&M

Floating wind projects move further into deeper water, and are not bound by the same seabed requirements as fixed offshore wind assets. As such, developers and vessel operators are faced with new challenges: longer crew transfer journeys, more exposure to potentially hazardous sea conditions, and riskier crew transfers. Access to floating wind farms also introduces several new factors such as wave height, distance to port, daylight hours, visibility, and vessel capabilities.

Studies on vessel motion for transfer ability and accessibility to floating turbines show that incorporating a SWATH (Small Waterplane Area Twin Hull) alleviates approach and docking challenges due to its enhanced stability. In fact, it’s estimated that the average operability of a SWATH design to be greater than 95 percent (versus 60-80 percent for other hull forms). The narrow main hull form of a CTV with a SWATH secondary hull gives the best of both formats — helping to minimize motions as well as fuel burn. This technology offers great operability for both transversal and longitudinal transfer approach, and robustness against wave heading.

A low-emission CTV option combining an efficient overall hull form, which includes SWATH for low response and foils, is an attractive proposition for operators looking after their teams, operations, and running costs.

By contrast, the current practice of dispatching large SOVs — usually carrying an excess of capacity to offshore sites for weeks on end — does not represent the most efficient use of time or money. If there are opportunities to transfer the crew to sites more quickly, not only will it make the best use of time around windows of adverse weather, but it will also contribute to the industry’s efforts to decarbonize, as these fuel-efficient vessels release fewer emissions.

Moreover, with assets further away from shore, it is critical that maintenance response times move faster accordingly. One added risk for offshore is the increasing periods of business downtime due to the positioning of assets in deeper seas; this can be mitigated by transitioning to leaner workboats for O&M requirements.

Compounding this, a greater stock of vessel options will be needed to adequately serve the growing offshore industry. Where SOVs take many years to build, smaller workboats like CTVs and SATVs can be built in just twelve months. The running costs are also lower, which, in the context of worsening seafaring conditions, makes them more attractive investment opportunities

It’s a defining moment for offshore wind. There is so much enthusiasm to harness this clean energy at scale, but this must be matched with operations that are both efficient and adapted to sea conditions that are expected to become more severe. Re-assessing the workboats currently in use, and taking up new opportunities with smaller, greener vessels, supports the industry as it builds for long-term sustainability.

Protecting Lives in US Offshore Wind

Up and down the East Coast, offshore wind projects are being driven to realize the goal of creating 30 gigawatts of US offshore wind power by 2030. Ensuring this growth requires organizations to increase workforces by the thousands. As windfarms are more often (by necessity) located in remote and hazardous locations, organizations will need to keep their newly expanded workforce safe, healthy, and protected.

Therefore, offshore wind projects need to ensure that the best quality medical, safety, and technical services are in place. From the initial phases of construction to turbines becoming fully operational, medical service providers should be experienced in responding to the unique safety challenges of offshore windfarms. Any chosen medical service provider has to deliver robust clinical support, and deploy specialist onsite medical professionals with the right resources, skills, and experience to effectively treat patients in an emergency. This is especially important when a worksite is many miles from the nearest healthcare facility.

Things for offshore operators to consider when sourcing a partner are:

Preparation is everything

Firstly, organizations should commit to pre-screening employees before they take up post at offshore job sites, thereby saving themselves from potential future operational disruption. If offshore workers deploy with pre-existing illness, injury, or other health risk factors, this can lead to increased risks for themselves and their teams. All of this has the potential to cause delays in operations due to sudden sickness or injury.

When it comes to standardization for pre-screening for offshore environments, the US is less developed than other parts of the world. Medical service providers can support wind projects by delivering the benchmark standard of pre-screenings from the UK, such as Offshore Energies United Kingdom (OEUK) medical exams. These industrystandard medicals ensure that personnel are medically fit to work in the environment. They are performed by trained and certified doctors who understand the offshore environment and remote and occupational medicine.

Bespoke medical facilities

Each wind project needs to carefully assess how its medical support services should be tailored to reflect the physical demands of the site. Often, it is beneficial for medical facilities to be integrated into a site, either temporarily or permanently. Integration ensures care for both occupational and non-occupational injuries and illnesses, together with around-the-clock services, such as telemedicine support and case management. This also limits the number of cases that require referral for further offsite medical care, which saves time and resources, and reduces personnel downtime. Offshore operators should consider a clinic on supporting vessels as essential: the cost-benefit of preventing operational delays due to workforce health issues far outweighs the set up and staffing costs. A clinic is far more than a medic with a first aid kit — it’s a facility that can handle advanced procedures onsite, as well as a broader provision of care.

Onsite health practitioners also play a vital role in providing education and encouragement for the adoption of healthy lifestyle habits among workers, to reduce the risk of injuries and illness. By interacting regularly and building trusted relationships with the offshore workers, onsite medics become highly-valued members of the team, ensuring that, when injuries or illnesses do occur, workers feel valued and readily seek medical support.

Enabling this swift communication and response is essential to prevent some of the potentially life-threatening injuries sustained on offshore windfarms. In emergency settings, health practitioners need to be able to adequately convey their physical findings and observations of a patient encounter, in order to ensure good patient care and reduce lost time due to injury or illness.

SECURE CRITICAL BOLTED JOINTS

Wind, Solar, Energy Storage Tech—HEICO Fastening Systems has precise, proven and reliable solutions to ensure critical bolted joints stay secured under dynamic loads, thermal extremes, high vibration environments and tight spaces.

Windfarm health care practitioners

When working offshore, due to both the remoteness and potential for adverse weather conditions, healthcare providers must be prepared to care for an injured or ill worker for an extended period of time, not to mention in a difficult and/or unstable environment. For example, if a worker requires medical attention on a turbine, moving them to a clinic to administer care may not be possible. This is where the onsite medical teams have the skills and the experience to reach and treat the injured or ill worker wherever they are located.

While offshore wind companies require every worker to complete basic first aid training, this only equips workers to render basic stabilizing care for a handful of life and limb threatening emergencies. Trained onsite medical providers will have far greater levels of training and experience, including Global Wind Organisation training, which includes climbing inside wind turbines. This additional experience allows them to deliver a

higher level of care in both emergent and non-emergent situations.

In order for any project to be successful during the rapid scale up of wind energy delivery, these are all vital skills, facilities, and services that companies must consider when it comes to hiring medical services.

Ending Turbine Fires Collaborating controls risk to wind turbines

It is not often that wind turbines catch fire. In fact, unless they have been struck by lightning, there is no reason why they should ever experience a total loss from fire to cause the financial and reputational damage that they do. Despite this, since October 2022, at least half a dozen incidents of wind turbine fires have been reported around the world, with considerably more that go unreported.

Two turbine fires occurred within days of each other at the turn of the year: firstly, at Galgenberg wind farm in southwest Germany, then at Cullerin Range wind farm in New South Wales. As is standard procedure when the nacelle of a turbine is on fire 100m above the ground, fire crews could only watch the fire burn out and secure the surrounding area from flaming debris.

Before that, in October, Diamond Trail wind farm in Iowa County suffered more severe losses as a three-year-old turbine caught fire. Surrounding fields were caught up in the blaze, and operators were obliged to take the entire wind park offline to conduct fire risk inspections, incurring significant disruption and great expense.

Why do we continue to take our chances with fire when preventative technology is right under our noses? It is time for us all to work collaboratively in the wind sector to protect assets against controllable risks.

Never Misaligned.

Truthfully, we can all do better

One of the stumbling blocks in wind turbine fire prevention is a lack of clarity over who is responsible. The simple answer is that we are all responsible.

Fire suppression technology can be installed at the manufacturing stage. Even so, the erroneous assumption that fire risk has been ‘designed out’ means that developers are not in a strong habit of asking manufacturers to install the technology.

Between owner operators and OEMs, fire risk is often not managed at all; both parties defer responsibility to one another. Consequently, the insurer is left to pick up the slack.

Owner operators will come to find that this is untenable. Despite capital flooding into the industry, we are seeing the insurance market harden in response to increased losses, and a perception that risks are being overlooked. Reliance on insurers to foot the bill ultimately leaves owner operators open to increased premiums and deductibles.

After a wind turbine fire, the average downtime is approximately 12-18 months, which could easily rack up half of million USD in lost revenue per affected turbine. If insurers no longer provide coverage for business interruption, could owner operators contend with such losses?

This unsustainable approach to fire risk is also enabled by inadequate legislation. Rather than being mandated, fire safety

features are left to the owner operator’s discretion, giving the green light to save money by turning down the chance to fit the technology — even though it costs less than a rounding error in renewable project budgets.

How we can manage fire risk together

There is only one way to guard against fire, and that is by fitting wind turbines with clean agent fire suppression technology that is safe for technicians and electronics. The problem is not a lack of a solution, but helping owner operators see the value of proactively solving their fire risk issue. Presently, the industry is crippled by a “hindsight is 20/20” mentality: the value tends to be understood, and the necessary technology fitted, only after the devastating impact of a fire event.

The prevailing attitude towards turbine fires is that, because they are relatively rare, owner operators believe they won’t be one of the unlucky ones. The fact is, however, that a turbine is a high voltage machine operating in harsh weather

Turbines continue to be lost unnecessarily to fire damage

Wind sector must work together to control risk as we embark upon historic expansion

conditions, producing plenty of heat, and will always require maintenance and testing to combat degradation.

Why gamble? We know that a claim for a burnt-out turbine comes in at 7-9 million USD, and that lost revenue from the downtime is significant. Instead, it is in the interests of insurers and owner operators — and the wind industry as a whole — to incentivize the fitting or retrofitting of proven fire suppression systems, with decreased premiums and lower deductibles for the project owner operator. This would go a long way towards reducing the volume of annual fire-related claims.

Governing bodies that are pushing for growth in the wind sector to meet netzero targets must recognize their role in safeguarding the wind investments (both public and private) through regulation. For much of North America, there is no mandate for wind farm owner operators to conduct a fire risk assessment or install fire suppression. As the sector continues its unparalleled growth, it cannot be long before legislation in wind goes beyond the current NFPA standards that generically apply to wind farms.

The consequences of inaction

Historically, there has been a taboo around disclosing wind turbine fires. Now, however, as wind projects are set for historic deployment, this legacy must be left behind. Not only is it unsustainable, but it prevents the industry from understanding the true level of fire risk. Failure to proactively protect against controllable risks like fire could threaten:

• The reputation of the wind sector

• Insurability of projects

• Profitability of projects

• The safety of working environments for personnel

• The safety of the surrounding environment

Controlling these risks is very easy, but it requires accountability across the board. Ultimately, owner operators should be empowered by the other key players in the wind industry to invest in appropriate fire suppression technology. The safety, financial, environmental, and reputational risks of wind turbines fires can be quickly reduced — if not eliminated — through industry collaboration.

The Nuts of Broken Bolt Removal

There are many bad feelings one may have when faced with a wind turbine not producing electricity to capacity. These tend to get even worse when you discover this is due to broken bolts. No place is off limits: you’ll find bolts inside the hub flange, main frames, rotors, blades, and nacelles. Since this could be considered a reoccurring problem in the wind industry, there are already conventional methods to deal with this type of issue, such as bolt extractors and welding nuts. However, there are many factors when deciding if these methods could be considered a timely solution. Then you have to decide if you’re willing to drill the broken bolts and risk damaging the thread. These situations happen with some frequency, and are part of everyday life on wind farms. Conventional solutions such as big bolt extractors, or going through the welding process, might not be able to remove the stuck bolts, and can even cause additional damages.

Additionally, the welding process requires a certified welder, which are in short supply (and often not readily available). Even if you do happen to have a good welder on hand, they may not be able to weld the broken bolt if it’s deep within the flange hole. With an ever-increasing turbine capacity leading to bigger blades, bigger tower sections, bigger flanges, and (finally) bigger bolts, the process of bolt extractions is becoming even more challenging. The number of repowering projects is also growing. Towers built 10, 20, and even 30 years ago are being refurbished. They’re also full of bolts that were often installed without proper torque control (over torque), leading to a potential nightmare.

To ease the shared pain of this difficult situation experienced by many site managers, OEM, O&M, etc., an old method commonly used in the heavy-duty industry was adapted. The first electrical discharge machines and methods were developed in 1940s by Soviets working on tungsten erosion and (unbeknown to the US) when, between 1960s and 1970s, workers were trying to make dies from hardened steel. During this time frame, a team of American scientists developed a method to remove broken drills and taps from aluminum castings. Afterwards, the machines were then developed and improved upon over the years.

The EDM process consists of metal being removed from a base piece (bolts, flanges, etc.,) by a series of rapidly recurring current discharges between one electrode, a dielectric liquid, and the metal piece. The combination of these factors disintegrates the metal parts, resulting in tiny metal particles (debris) to be carried away by the liquid.

Why use the EDM instead of conventional processes?

In this EDM process adaptation for wind turbines (for both down and up tower) the disintegration process is the same as the conventional process, but modified to make it substantially safer and cleaner. The up tower rigging process is carried out following all wind industry safety requirements. The disintegration equipment is designed and manufactured to avoid electrical shocks. In case of any malfunction, whether due to operator or device failure, the equipment automatically shuts down. Environmental safety is also paramount; the process uses a water recycling system in which the water resulting from the disintegration goes through a filtering process,

and returns to the discharge system. The resulting byproduct contains only a mix of water and metal particulates, posing no risk to the environment.

In addition to being safe and clean, the EDM process is also faster, in some cases, when dealing with multiple broken bolts. This is a big advantage, as you’ll normally encounter multiple broken bolts on larger components. During the repowering process, it’s typical to find mulitple broken bolts in each component. With this in mind, the EDM is designed to reach several broken bolts (around 6 or 7) at the same

time, using a single machine setup; only the electrode needs to be repositioned. Not only does this save time during the repair, but also results in getting back to operation in a more efficient time frame overall. The EDM process also reduces the odds of having thread damage, when compared with the standard bolt extraction process of ‘’drilling’’ the broken bolt in parts inside the flange hole. Excess damage is avoided because the EDM process uses electrodes manufactured specifically for each type of bolt. For example, one specific electrode is manufactured

to match an M36 broken bolt. The electrode can have two different profiles for one specific bolt, since there are two different methods for the bolt extraction process. The first process consists of ‘burning’ the bolt core, and then using a bolt driver to unscrew the stuck bolt from the inside out. The second process involves ‘burning’ the bolt very close to the thread dimension (without interfering with the thread), breaking the bolt into small parts, and removing the small parts from the flange hole. A case study should be conducted prior to the start of every job to evaluate which process best fits each situation. The process is also applied in situations where access to the broken bolts is restricted or obstructed. The machine contains several extension arms, or offsets, allowing it to reach points that a standard process could not.

EDM methods are an appealing option for broken bolt extraction situations. The methodology may be old, but when applied to modern problems, becomes an innovative, safe, and clean solution to a major obstacle faced by wind sites.

Foundations for wind turbines and transmission lines normally consist of large, reinforced concrete spread footings. Compression loads on soil are only supported by the soil; overturning loads are resisted by the counterweight provided by the concrete foundation. The changes in loading from compression to uplift can cause a fatigue problem, which is difficult to predetermine. Consequently, overturning of the wind turbine may result (Figure 2).

For foundations on soil, an alternative post-tensioned foundation system was developed using micro piles supporting a smaller foundation-pile cap. Not only does this micro pile system minimize, or eliminate, the fatigue problem, but it can also provide a total foundation cost savings of about 25 percent (75 percent smaller foundation area, 40 percent less in concrete, 70 percent less reinforcing steel).

Design Objectives

• Achieve a design load in compression and/or tension with the required factor of safety.

• Provide a rigid foundation.

• Improve rotational stiffness and reduce movement of the foundation.

• Reduce excavation and backfill required for the pile cap/tower foundation.

• Require only small drilling equipment.

• Reduce consumption of materials to optimize foundation efficiency and performance.

A groutable void form (GVF) temporarily separates the pile from the pile cap during stressing and testing to a load higher than the design load in compression and tension, while also allowing for some range of pile movement. After post-tensioning, the GVF is filled with cement grout to also transfer compression loads to the pile.

Prime Advantages

1. Controls foundation settlement and prevents overloading the soil (bearing capacity failure) with a prescribed sequence of post-tensioning.

2. Post-Tensioning in balanced anchor groups permits gradual load transfer into the piles, without overstressing the soil.

3. Settlement of the foundation cap is minimized as the piles take over the compression load from the cap.

4. Fatigue failures can be eliminated since the post-tensioned tension and compression loads are higher than the design loads and, as such, minimize or eliminate movements during load changes.

5. Reduction of concrete and steel lessens environmental impact.

Method 1 - Micro piles are installed prior to placing the concrete foundation cap.

A foundation for a 1.6 MW wind turbine was constructed in Tehachapi, California, using 300mm diameter pre-drilled posttensioned micro piles and GVFs. The 100m tall lattice tower was founded on five individual pile caps, each supported by 4 micro piles. The post-tensioned micro pile/GVF system was load tested to provide assurance that the construction cost and long-term maintenance of the micro pile system could be reduced.

Method 2 - Micro piles are installed after placing the concrete foundation cap.

The advantage of the second method is that the micro piles are drilled through pre-formed sleeved holes in the foundation cap fitted with a pre-installed GVF under the foundation cap.

The disadvantage is that the drill hole size is determined by the smaller sleeve, inside the foundation slab, which does not provide sufficient cement grout body under the GVF. The smaller sleeve size is dictated by the size of the bearing plate for the micro pile.

When using the grout injection bored method with hollow bars, however, the cement grout is injected simultaneously during the drilling operation. The drill bit has small diameter side holes through which the grout will exit under high

pressure, as during jet grouting. This will flush and create a larger size drill hole than the drill bit size under the GFV, creating a sufficient cement grout body underneath the GVF. This also improves the condition of the ground around the micro pile, and creates a higher skin friction capacity.

Stressing of the micro piles simultaneously, in pairs, will pre-stress the piles and post-tension the foundation before the GVF is filled with cement grout.

The number of Micro Piles stressed in pairs is dictated by the compression load capacity of the soil. When this load is reached, the GVFs are grouted. After the grout has reached sufficient strength, the stressing procedure can continue.

Wind turbine and foundations composed of posttensioned Micro Piles with GVFs improves safety and lowers cost, making this system a competitive alternative to large reinforced concrete and large mono-pipe pile foundations on soil.

Ward Off Wind Turbine Failure

Lubricant and filter analysis are key

Hurricane-force winds, raging seas, and scorching deserts are just a few of the harshest environmental conditions that wind turbines need to withstand. To ensure dependability, oil analysis and filter debris analysis (FDA) are an integral component of most wind turbine reliability programs.

Offshore wind turbine fail, on average, 8.3 times each year. Among the reasons for failure are contaminants such as wear, rain and sand, and moisture intrusion. With regular lubricant analysis and periodic FDA, much of this can be caught and remediated before damage occurs.

Typical oil condition monitoring practices in the wind industry include a regular review of the main turbine gearbox oil and the hydraulic system fluid for basic property analysis, degradation contamination, and wear. Much of the oil sampling and testing is performed not only to verify the condition of both the oil and equipment, but also to satisfy the requirements of the system warranty. Approximately 75 percent of customers sample and test the oil every six months. The remaining 25 percent review the oil on a more frequent basis, at least every three months.

Oil and Grease Analysis

While there is some value to occasional oil and grease testing, it’s really trend-based analysis that will minimize equipment downtime, streamline maintenance, and protect warranty claims.

Components that should be tested:

• Turbine gearbox

• Hydraulic pitch system

• Drive gears: pitch and yaw

• Bearings: main shaft, generator, pitch and yaw

Tests should include:

• Water Content (Karl Fischer Water) D6304

• Acid Number (TAN) D974

• Viscosity D445

• FTIR Spectroscopy E2412

• Particle Count (ISO 4406:99)

• Ferrous Wear Concentration

• Analytical Ferrography

The difficulty in accessing the gearbox is the primary reason that, unless there is an urgent reason, filters are usually analyzed only after changeout.

• Wear, Contamination, and Additive Metals (Elemental Spectroscopy) D5185

Reliability personnel should expect a detailed report that includes information on lubricant condition during operation and wear/contamination — type, source and degree. All of this should be accompanied by technical interpretation.

Filter Debris Analysis

Surprisingly, 95 percent of the wear debris that may provide useful information about the condition of the turbine never makes it into an oil sample — it’s contained in the filter. This is due to the fact that wind turbines use increasingly finer filtration to ensure long lifecycles. The only particles that can be analyzed in conventional oil analysis are those that are already present in the oil and smaller than the filter's pore size, or those that are introduced into the oil before filtering. Once the filter is discarded, any potential insights from its analysis are lost.

Justifications for filter analysis:

• Catch the wear debris caught in the filter that an oil sample would miss

• Benchmark metallic wear generation rates of machinery components

• Determine the size and quantity of abnormal metallic wear debris

• Determine specific elemental makeup of wear debris captured in filters

• Develop no-go/go limits for critical assets

• Complement an existing oil analysis program

By analyzing filter debris, the lab can identify pollutants and wear indicators that are either removed from the oil by the filter, or too large to be detected by traditional elemental analysis.

Suggested Method

The lab should clean and examine wind turbine filters methodically, using a proven FDA technique. The self-contained FDA instrument should employ an automated filter washing procedure to completely and repeatably remove all inorganic debris from the filter. The filter should then be placed in the system wash chamber, where fluid and compressed air are used to clean the filter of any debris. The filter debris-containing wash should then be collected and analyzed.

While there are logistical issues with FDA for wind turbines (the most obvious being the size of the filter and the difficulty handling it), experts recommend testing all used filters before they are discarded. Consider that the filter element holds a wealth of historical diagnostic information that has been accumulated over the entire service life interval.

Lab Services

In addition to comprehensive oil analysis and filter debris analysis for wind turbines, other lab tests for wind turbines may include:

• Material Identification Analysis There are times when a sample pulled from a lubrication system has concerning anomalies. In those cases, routine oil analysis is not enough. Material Identification Analysis (MIA) is a forensic-level service that includes an in-depth investigation designed to identify the root cause of a problem or the origin of foreign material. The analysis employs various analytical and sample preparation techniques that lead to recommendations for resolution.

• Compatibility Analysis Mixing incompatible lubricants is a common problem. It creates issues such as excessive foaming, formation of precipitates or deposits, and loss of key performance characteristics like water separability. ASTM D 7155

Standard Practice for Evaluating Compatibility of Mixtures of Turbine Lubricating Oils should be used as the guideline for compatibility testing.

• Varnish Potential Analysis Varnish is an insoluble film that coats the internal components of machinery. This can devastate wind turbine operations. The debilitating effects of varnish are well documented. The complexities associated with detecting varnish potential render routine oil analysis ineffective in reporting varnish. Varnish Potential Analysis testing monitors the contaminants responsible for varnish, and alerts customers on when to implement appropriate, corrective actions before costly damage occurs, and there is unnecessary downtime. Ignoring regular lubricant and periodic and FDA analysis can be costly. Here are just some of the pricetags associated with replacing the following wind turbine components:

• Blade: $391,000-$547,000

• Blade bearing: $62,500-$78,200

• Gearbox: $628,000

• Generator: $314,000

• Electronic modules: $16,000

For all machinery — especially expensive machinery such as wind turbines — the cost of condition monitoring pales in comparison to the cost of replacing damaged and destroyed components, not to mention the associated downtime. Wind turbine operators should look for a lab that can efficiently process and analyze routine samples, and produce a straightforward report that quantifies machine health, lubricant condition, and contamination.

Michael Barrett is Vice President at Eurofins TestOil, where he has worked for 30 years. He led the Eurofins TestOil effort into researching varnish 15 years ago, ultimately developing a solution for helping customers understand varnish potential in their equipment. Today, he is responsible for directing the Eurofins TestOil marketing and sales efforts, working closely with customers to help them develop successful oil analysis programs. He has also spoken at conferences as an expert on a variety of oil analysis-related subjects.

How to Outsmart Mother Nature

Regardless of the season, the power industry is now facing greater challenges than ever to keep the lights on, as weather trends intensify. Extreme conditions such as prolonged drought, intense heat, high winds, sub-zero temperatures, large wildfires, heavy rains, and flooding can hinder energy production and elevate demand for electricity. This often results in increased brownouts, rolling blackouts, or even total power outages.

Renewable energy capacity is growing at a record pace. As the energy mix begins to tilt in favor of renewables, there is added urgency to ensure that these assets are able to withstand whatever extreme weather conditions Mother Nature dishes out. This is particularly challenging when these assets are in remote areas with rough terrain, far from maintenance staff, and exposed to the elements 24-7-365.

Utilities must leverage new technologies to help weather the storm so they can continue providing reliable power, and maintain grid stability throughout these events.

Owners and operators of diverse renewable generation and energy storage assets often have limited access to production, environmental, maintenance, and performance data. This hinders their ability to optimize operations, especially when dealing with the stress of extreme conditions. Full data access, along with a holistic view of operations, will improve situational awareness, which helps ensure that power producers are better prepared for hard-to-predict events, especially as they navigate fleet transitions to greener energy. Let’s take a closer look at how a portfolio of purpose-built renewable energy software and automation solutions can reduce complexity, and mitigate the potential negative impacts of dangerous weather events. Advanced value-driven solutions can help to proactively address impending issues, thereby reducing downtime, as well as the time and expense of servicing damaged equipment.

It starts with an integrated ecosystem

Utility-scale renewable energy and storage facilities generate massive amounts of data that exponentially grows as the portfolio expands. Unfortunately, this information is generated by numerous disparate systems, creating a siloed infrastructure that traps data locally. The result is increased complexity, especially for operators. An integrated, holistic automation ecosystem eliminates data silos and complexity by centralizing, contextualizing, and securely managing and communicating critical information across an organization — from the field devices, to local control, enterprise operations, and grid management systems. When the right personnel has full access to operational and financial data (when and where it is needed), analysis, trending, and forecasting are improved.

Clear view from a single pane of glass

Renewable asset performance management and SCADA software (created specifically for green energy by industry pioneers) play a significant role in providing a unified view of unfiltered real time operational data — accessible anywhere, anytime. Implementing a scalable, asset performance management software solution that integrates data from any system, regardless of supplier or vintage, provides greater insights into equipment health. Full access to operations information puts the power of maintenance and optimization opportunities back into the hands of owners or operators, enabling quick and confident decision-making, which helps to avoid costly problems.

Predicting the unpredictable

Asset monitoring and health analysis deliver vital operating and maintenance information to key personnel so they can proactively manage assets, and improve reliability. For renewable assets with high-performing rotating equipment, such as wind turbines and hydro plants, condition monitoring systems with vibration analysis can help reduce costs and downtime by predicting impending issues earlier in the failure curve. With automatic and continuous monitoring of equipment operations, power producers can quickly and efficiently identify, diagnose, and resolve a problem before it escalates.

Artificial Intelligence turns data into actionable information

Data analytics is a key enabler of digital transformation, making it possible for renewable power generators to shift how they operate, becoming more efficient and agile and, consequently, more competitive. Advanced analytics can transition power producers from a reactive operations and maintenance approach, to a predictive or prognostic strategy. This actionable intelligence (built directly into the automation platform) unleashes

efficiencies that improve operational situational awareness across a fleet of renewable assets. At the local renewable asset or site level, expert-system-based predictive analytics enable immediate resolution of short-term impending process or equipment anomalies, while augmenting centralized remote operation and M&D center capabilities for longerterm, strategic analysis.

Strategies in action

Wind turbines, notoriously located in remote, hard-to-service areas, are designed to withstand severe environments. As these turbines age, they become even more sensitive to stressful conditions. Owners and operators can help protect these assets during volatile weather seasons by implementing some of the solutions below.

• Advanced software with logic can automatically restart a wind turbine that has stopped operating due to stronger-than-usual gusts above the cut-out speed.

• Electric pitch and safety systems automatically and accurately adjust a wind turbine’s blade angle based on varying wind conditions, protecting the turbine from high wind speeds.

• Purpose-built condition monitoring for wind power can detect rotational imbalance caused by extreme heat exposure or icing on the blades, and trigger alerts to the right personnel for immediate action, before the issue escalates.

• Modern wind farm control strategies can detect when units are shutting down in response to temperature deviations and, in response, adjust the curtailment setpoints to the other units to maintain the Independent System Operator’s desired output.

Golden Valley Electric Association (GVEA) serves over 36,000 members in Interior Alaska who are on the front line of climate change. The GVEA recently completed a digital transformation project to improve the management of Eva Creek, Alaska’s largest wind farm. As part of the project, GVEA implemented software and automation technologies that provide more accurate equipment diagnostics and analytics. Increasing visibility into the wind farm’s operations has already had a positive impact, boosting the reliability of GVEA’s wind turbines, and contributing to a 65 percent reduction in operations and maintenance costs.

As reliance on renewable energy grows, it is vital to keep assets in operation, regardless of changing weather conditions or difficulties reaching equipment in remote locations.

Harnessing and contextualizing data through an integrated, renewable-specific ecosystem of purpose-built software and technologies gives operators actionable intelligence to make swift decisions, helping to limit (or even prevent) damage and downtime. With these insights, power producers can build and scale sustainable operations with confidence, contributing to a more resilient, responsible, and smarter power grid.

Motor brakes that eliminate pitch drive maintenance

The Magnashear motor brake from Force Control Industries eliminate pitch drive maintenance by eliminating the root cause of maintenance required for traditional dry braking systems, degradation of friction material. Oil Shear technology is a unique technology which transmits torque between lubricated surfaces, thereby eliminating wear on friction surfaces. A fluid recirculation system dissipates heat thus eliminating heat build-up which causes friction material glazing, another common problem in dry braking systems which requires adjustment. Oil Shear eliminates the wear and thus the need for adjustment, and significantly increases service life (typically to 5-10x that of dry braking systems). Oil shear technology also provides a smooth cushioned stop which reduces shock to the drive system, further extending service life of downstream components. The totally enclosed, IP56 rated, Magnashear brakes are impervious to moisture, dirt, and dust and are suitable for critical wind turbine applications such as pitch drive systems.

A solution for hauling longer wind turbine blades

XL Specialized Trailers’s BladeMate Flip Extension provides significant cost savings to haulers over purchasing a new trailer. XL’s 27' long Flip Extension can be added to the rear of XL’s BladeMate trailer, or any blade-hauling trailer. The final trailer length will depend on what model the flip extension is paired with. For example, with the addition of the Flip Extension, XL’s BladeMate reaches to a length of 211'. When moving the empty trailer, a driver can flip the Extension up, retract the trailer, and have a 53' long return trip with reduced permit costs. The XL Blademate Flip Extension was made to be user friendly. By moving the lever at the front of the trailer, six'' hydraulic cylinders flip the extension up or down within minutes. The cylinder linkage can be unpinned and lowered flat to allow for more loading space on the top of the trailer. The rear bolster, at the end of the Flip Extension, offers a 20,000lb capacity, making it suitable as the rear-loading platform for the common two-point load set-up. The Flip Extension is secured with a lug and pin system, allowing the tail to be completely removed when it is not needed. The XL BladeMate Flip Extension offers benefits to the driver even when hauling shorter blades. If the driver uses the Flip Extension instead of fully extending the BladeMate trailer, the wheelbase of the trailer is shorter and reduces the trailer’s turn radius.

High-speed vacuum circuit breaker

EMA Electromechanics has designed and manufactured the high-speed Grounding Breaker, a patented technology created to mitigate TOV on wind, solar, or storage energy MV circuits. In solar application, during a line-to-ground fault or a load rejection, the MV circuit might be islanded with the inverters connected for some cycle of wave in order to commit to the voltage ride-through (NERC PRC-024). Inverter’s islanding detection method (IDM) might not be fast enough to differentiate a MV circuit islanding than a voltage excursion at POI (generation remains connected for some cycles). The high-speed grounding breaker is a fast and clear signal to all inverters shut down at the same time, which avoids unnecessary ride-through, and is reliable TOV protection. EMA offers 38kV vacuum grounding breakers and conventional circuit breakers for outdoor applications.

Come Hail or High Water

Don’t let extreme weather impact your

revenue

Whether it’s wildfires, hurricanes, or hail, natural disasters devastate solar power infrastructure. This is particularly true for asset owners of utility PV, where extreme weather can cause significant downtime, repair costs, and revenue loss.

Last summer was the worst on record for natural catastrophe claims, with far more damaging unmodeled extreme weather events than traditional natural catastrophe claims. Hail losses in Texas alone last year caused about $300 million in solar damage, nearly ten times the estimated losses from Hurricane Hanna (2020).

Let’s start with some context: When a wildfire devastated a 20-megawatt solar plant in Kern County, Calif., in 2020, it looked at first as if the entire 200-acre site had been destroyed. Firefighting helicopters had dumped tons of water on the plant trying to douse the flames, flooding many of the site’s inverters.

The asset owner brought in an experienced disaster management team to survey the damage and create an intricate plan to deconstruct, salvage, repair, and replace vital equipment. The team restored the plant two months faster than competing bidders, saving $2.6 million, and rescuing equipment that otherwise might have been scrapped.

Here’s a strategic roadmap of the best practices that helped them do it.

1. Assess and document damage

Don’t let initial impressions mislead you. Damage that first appears minimal may be concealing more significant issues. Document everything, even superficial effects. Take pictures — at least four or five for everything that may require attention. Note components that may no longer be in production, and determine which OEMs will play significant roles moving forward.

For more extensive damage, consider a high-resolution aerial scan of the site to map destruction levels. Insurance companies often cover such inspections because they want to know what they’re dealing with just as much as you do. Infrared views can identify thermal problems invisible to the naked eye.

2. Salvage and stagger work efficiently

Before restoration work begins, establish standards for testing damaged equipment, and establish criteria for what warrants repair and what calls for replacement. The right restoration partner will have the expertise required to implement these procedures. Salvaging components requires flexibility. Maintain quality, but stay alert for opportunities to continue using viable parts. For instance, instead of replacing an entire inverter, explore every option to re-energize the equipment. Successful salvage can save hundreds of thousands of dollars over replacement.

It’s critical to get as many sections of the plant operational as fast as possible. This can go a long way towards restoring revenue streams, even while restoration continues elsewhere on the site. At the Kern County plant, the recovery team consolidated salvageable parts to get sections back online while awaiting replacements for destroyed components.

When possible, stagger the work to prioritize production; if one inverter is down simply due to a ground fault, but the rest of the array is in good shape, prioritize restoration there to get a section of the plant back online.

3. Repair and replace old with new

It’s tricky to blend legacy equipment that’s no longer being made with modern components. Look for a partner with the expertise required to creatively weave in stillfunctional older parts with state-of-the-art PV technology.

In the case with the fire damage in Kern County, the recovery team sourced, engineered, permitted, constructed, and commissioned a hybrid system that melded older 1,000-volt central inverters with modern 1,500-volt systems. The effort brought the entire plant back online 60 days faster than a competing bid would have, avoiding $1.2 million in lost revenue. Because the restoration partner was also an EPC with O&M capabilities, the project further benefited from efficient labor and competitive materials pricing, saving the owner $1.4 million more on reconstruction and parts.

4. Mitigate equipment supply risks

Today’s ‘perfect storm’ of supply chain and inflation challenges are exacerbating the complexity of extreme weather claims.

A partner with EPC capabilities can streamline the wait for parts, ensuring availability through Tier 1 procurement agreements. Particularly with today’s supply constraints, you need experts with a deep supply network and, ideally, an extensive inventory of spare parts on hand at regional warehouses.

5. Make insurance a recovery partner

Insurance adjusters often are brought in too late in the restoration process. Instead, establish a dialogue with your carrier early on to ensure familiarity with PV best practices, and bring all stakeholders into alignment throughout the project.

Adjusters were active from the start in Kern County, where assessments were needed on the remains of 1,000 modules, scores of junction boxes, and a DC collection system — all of which had been subjected to both blistering heat and drenching water. Delicate diplomacy is needed to reach agreement on a restoration plan.

Getting insurance up to speed from the project’s genesis made it easier to streamline the claims process, and support rapid and optimal insurance coverage. Select an experienced recovery partner that can help you save valuable time in

6. Guaranteeing PV profitability after the crisis

Consider the advantages of long-term partnerships as you put together your recovery team. A full EPC partner with extreme weather mitigation know-how can offer in-house engineering teams, designers, construction management, and supply capabilities to ensure strong post-recovery performance.

In addition to meeting energy production guarantees after an extreme weather event, your EPC should offer dependable O&M services to keep things running

smoothly well into the future. These experts bring additional plant operation solutions for long-term maintenance, repair, and energy optimization.

Partners who also offer repowering services can help address unreliable equipment that diminishes plant performance. Recertification programs can extend maintenance to salvage usable equipment for future use, and source parts faster than OEMs.

Salvaging solutions from the floodwaters

When two hurricanes hit a 92-megawatt plant in the Southeast, ten out of the 40 power conversion stations were flooded for days with nearly 18 inches of water. Because the plant’s operator had taken all of the inverters offline before the storms hit, condensation had formed inside all of the stations. Unfortunately, rather than voiding the warranty on just the flooded inverters, the manufacturer denied responsibility for any of them.

The plant owner was looking at substantial financial losses, not to mention potentially months offline. A restoration team proved that a pre-existing design flaw in the inverters had caused the condensation, which prompted the manufacturer to restore warranty coverage.

Facing long lead times to replace the inverters covered by the insurance, the team instead salvaged and refurbished the units — saving $4 million in replacement costs, and avoiding $400,000 in lost revenue. Ultimately, the plant was fully restored 152 days faster than the competing solution, netting an overall savings of nearly $2.5 million.

Don’t wait for natural disasters to strike

Site recovery takes more than cobbling pieces back together again after a disaster; it involves complex processes that demand unique skills and expertise beyond simple construction. Planning ahead can make the difference between struggling to get back online, and coming back at full strength. To weather whatever storms may come, plant owners should screen potential partners today, and enlist their help to develop contingency plans for critical equipment and parts, safeguarding future profitability.

Solar for Florida’s Hurricane Zone

The challenges of designing the uplift stability of solar panels in the Florida counties of Miami-Dade and Broward are immense, and with good reason. Hurricane Andrew made landfall in South Florida in 1992, with wind speeds recorded up to 177 mph. The $25 Billion worth of damage was primarily caused by these high winds (as opposed to storm surge, which typically causes the most damage). Accordingly, the 2020 Florida Building Code specifies the design wind speeds of 175 mph for Miami-Dade, and 170 mph for Broward (FBC 1620.2). Respectively, this is a 64 percent and 59 percent increase in wind speed — far above the 107-mph limit used in Miami, Indiana. However, since wind pressure is the square of windspeed, the increase in wind pressure actually ends up at 167 percent for Miami-Dade, and 152 percent for Broward County.

In addition, the Florida Building Code requires that a minimum of Exposure C is used in high velocity hurricane zones (FBC 1620.3). Exposure is the consideration of what other types of structures are near the structure in question. A house in a neighborhood with other similar houses around it will be Exposure B; a farmhouse with fields surrounding it will be Exposure C. This means another increase of about 40 percent for a 30-foot-tall

This image shows a condition where a plumbing vent has interrupted the array layout. This results in the adjacent North panel having an exposed edge and, consequently, a significant increase in design uplift.

This model shows the dimensions of the panels from the edges of the roof. Note that the building height h=13’ so any panel within half that distance (7'-6") from the roof edge must have the gE factor of 1.5 applied.

The uplift effects on the rail and attachment anchors is manageable. Reducing the spacing of the anchors will shorten the span of the rail, thus lowering the bending stress. This also

that these ratings are assumed to be for portrait orientation only, and do not apply to the long side of the panel placed parallel with the rails (landscape).

Back in Miami, FL — given the example above — as long as we stay in zones 1 or 2e AND we make sure that all edges of the array are not “exposed”, these panels will be sufficient. In a perfect world, we can ensure this every time. However, in reality, more often than not, we cannot feasibly keep all the panels within these conditions without diminishing system sizes or making significant changes to the building components itself.

We All Need to Become “Weather Wise”

Throughout college, and while working toward a meteorology and climatology degree, one of my favorite magazines was called “Weatherwise”. The magazine is published by the American Meteorological Society, and includes this quote from Benjamin Franklin: “Some people are weatherwise, but most are otherwise.” One reason I enjoyed the magazine was it was low on the technical details and research, and focused more on extreme weather, climatology, and general, good to know, weather knowledge. To this day, nearly 40 years later, it is still one of my favorites.

Would you consider yourself weather wise? If you are reading North American Clean Energy, you’re involved in the renewable energy industry. This is an industry that is driven and created by the air that can cools us on a hot summer day, the sun that softens the bite of a cold January morning, and the river that provides a relaxing boat ride behind a hydro dam. It’s also an industry that feels the wrath of the new normal in weather and climate extremes. A weather season no longer passes without us hearing of record setting events from hurricanes, severe weather, and high winds, once in a lifetime floods, and all-time record snowfall (as seen in California this winter). Your assets and your staff have to co-exist with this new normal, one which is likely not going to change and, hopefully, will not worsen. Let’s take a look at some of the most troublesome weather extremes, how they impact the industry, and what you can do about them.

Hail

A forecast of hail will quickly grab the attention of anyone involved in the solar industry. It should not surprise you that recent papers document how annual large hail environment days are increasing. The most statistically significant areas are in the Plains, and then east through the Midwest and Ohio Valley. In other words, geographic areas where much of the new, utility scale solar is being built. The same studies show that verified large hail reports have been trending upward since the early 1980s.

What does this mean to your solar operations? What can you do to mitigate this risk? Operational forecast techniques, and data to identify these events, has improved dramatically in the last decade. The storm environment that produces large, damaging hail can now be identified

can be formulated; when the storms begin to develop to where they pose a threat to your assets, impact alerts and warnings are available. These notifications predict the storm path, and impact arrival time to your site, giving you enough time to get panels into a defensive position.

Severe Weather

Nothing is more important to a business than the safety of its employees. Many renewable energy employees spend the majority of their time working outside in the elements — sometimes performing work that requires extreme safety, even without mixing in volatile weather. This past fall and winter alone, this country has endured severe storms and tornadoes in the state of Iowa, thunderstorms that race across the southern plains at 80 mph, and lightning as far north as southern Ontario. The message: There is no off season for severe weather anymore.

Lightning no longer goes into hibernation across much of North American from November to early March. While the frequency of these events may decrease, you now need to be on guard for extreme weather year-round. Continuous training for new hires on weather policy and standards should continue throughout winter, including a review and further training with staff on commercial weather solutions you may employ. Address gaps in your “weather tools” now, and make sure standard procedures are in place for the busy spring and summer storm season. The weather tools and methods you employed may have been good enough 10 years ago, but today’s environment demands a commercial, business grade solution for safety and extreme weather mitigation. The expense is minor, when considering the safety of your employees and protection of your assets.

Wildfires and Drought

Drought conditions are linked to wildfires. Prolonged drought or fast developing flash droughts are precisely the events that contribute to extreme wildfires. The heat experienced today is more extreme that it used to be; just ask anyone who’s been living in Seattle or Portland all their life. Forests, brush, grass fields, etc., become tinder dry in a much shorter time. Wildfires whipped by unseasonably strong winds race across not only forest and grassland, but urban areas (i.e., the Marshall Fire that raced through Boulder Colorado on December 30th, 2021). Commercial weather solutions that identify fire danger areas before the fire starts are essential. Should a wildfire threat to your assets exist, these solutions also track and identify all current wildfires, providing continuous updates and alerts to your staff and control centers. This will allow you ample time to evacuate staff safely, and take any mitigative action you can to lesson the impact on the asset.

Get Weather Wise

It’s time to raise your level of weather awareness and preparation. As a meteorologist who’s been at this since the late ‘80s, I can tell you that there are far fewer weather surprises now. What may be perceived as a surprise is more likely to be a lack of awareness and preparation. The term “vigilant” is heard more regularly these days, but not often associated with extreme weather. I recommend incorporating that term into your weather planning and preparedness. In other words, become weather wise.

Built To Last

Extreme weather is occurring more frequently all across the U.S. That’s why Terrasmart continues to improve our product design and technology monitoring software, ensuring our ground mount products are built to last in all weather occurrences.

In utilizing Terrasmart’s 4P model when it comes to protecting your solar tracker site, our PeakYield™ technology will Produce, Predict, Protect and Perform safely and efficiently, so that your solar asset remains unharmed by supreme weather conditions. We stay ahead of the weather and will blow away any doubts.

The 4Ps of Solar Tracker Software

To steer success in utility-scale solar, produce, predict, perform, and protect can generate a roadmap to help developers and asset owners source the right single-axis tracker for their project, for peak performance in the toughest weather.

As structural and mechanical advances let manufacturers scale and keep costs down, the next frontier involves performance monitoring and controls software. Owners and developers are constantly exploring opportunities to:

• Increase energy yield, and reduce downtime

• Minimize weather-related losses

• Optimize tracker performance, and boost project returns

It’s critical for decision-makers assessing solar tracker options to evaluate how control software impacts a project’s long-term performance, particularly during extreme weather events. The 4Ps of tracker success help to ensure optimal reliability, system yield, and financial returns.

Intelligent tracker software is the key. Today’s trackers are far more advanced than their predecessors, capable of operating on sites with high wind speeds and snow loads. But the technology is just beginning to reach its maximum potential.

Extreme weather calls for smart systems

When assessing control systems for tracker technologies, look for machine learning capabilities, real-time data, and weather monitoring systems that proactively track, alert, stow, or troubleshoot your SAT’s production. Some important features to seek include:

• Real-time data and dashboard with email and SMS notifications to guide predictive and corrective maintenance, such as project mapping and row-level monitoring.

• A smart weather API and on-site sensors that forecast and monitor snow, wind, and flood to alert you when trackers should be stowed before bad weather can damage systems. A stow angle optimized at 60 degrees helps distribute and stabilize loads across rows.

• Remote software updates and a real-time cellular connection to allow easy enhancements and remote troubleshooting, keeping systems up-to-date while reducing truck rolls on site.

• Proprietary AI cloud systems that feature powerful machine learning to run predictive analytics, reduce downtime, and maximize energy yield.

Produce more energy

Using adaptive machine learning and historical data, tracker software can project where the sun will be at different times of the day, then optimize module positions to gain maximum energy yield. Advanced backtracking algorithms minimize rowto-row shading. Configuration parameters and sun angles help determine how a row should be positioned to avoid shading its neighbor, while also considering the terrain of rows directly to the east and west.

Predict performance

Cloud-based data supports predictive analytics and maintenance to address issues before they disrupt production — and revenue. Machine learning algorithms can detect when a row is not tracking properly so you can fix issues before they impact performance. This saves on cost, reduces downtime, and mitigates worst-case scenarios. User-friendly dashboards allow you to always know how your site is performing, whether across all projects, or drilling down to the row level to understand issues. To contend with an increasing number of extreme weather events, smart systems are integrated with weather APIs to

monitor local weather forecasts. If wind variables exceed a predetermined threshold, equipment can be stowed before the storm hits. The modules then remain stowed until all weather alerts are cleared and sensors report consistently safe conditions once again.

Protect from weather events

Extreme weather can damage assets, increasing remedial costs, jeopardizing operations, and driving up O&M budgets. But tracker technology can mitigate weather-related risks. A feature called smart stow can use weather APIs to react to alerts from on-site weather stations about when incoming storms pose a threat. The system can stow modules proactively to protect against the potentially damaging effects of high winds and deep snow.

Some intelligent systems include distributed row box intelligence that allows the rows to stop tracking, and get to a safe position if motor currents exceed thresholds. Distributed intelligence also can prompt safe stow when batteries are low, or if the row boxes cannot communicate with a network controller. After local issues are resolved, the rows automatically resume operations.

Perform easier O&M

Some tracker software packages offer remote access. Gone are the days when a bug in the system meant rolling a truck to the site to find out what went wrong. Paired with historical data, real-time monitoring down to the row level allows for remote

troubleshooting and quick diagnosis. Systems with dynamic administrative panels let users see inside the project site to conduct data analysis to identify the issue. Other value-added features include zone controls that allow moving portions of a site for routine maintenance like mowing and washing, without compromising optimum power generation.

Asset operators often must deal with rows that aren’t tracking properly. Look for smart systems that create tracking projections for each row, and send notifications when a row fails to meet its projection. This lets O&M personnel address issues quickly to maintain optimal production.

Intelligent tracker software will play a pivotal role in giving projects a competitive edge. Control systems with advanced AI and machine learning features will minimize weather-related risks like hail and high winds, helping the solar industry scale new heights in energy production.

Bigger in Texas Storm Uri

highlights importance of Time Series data in solar project design

Two years ago, Storm Uri unleashed a deep freeze over Texas, causing widespread power outages that affected more than 4.5 million people. The drastic changes in temperature during the storm not only reduced natural gas production and froze wind turbines across the State, but also had widespread impacts on solar plants.

When the grid network collapsed during the storm, many PV plants were unable to restore power after shutting down, because the total Open Circuit Voltage (VOC) was higher than their inverters’ DC start-up voltage range – leading to performance issues and impacting PV power components.

In retrospect, Storm Uri provides an important lesson in solar project design: Having access to solar Time Series data, and using the information gathered from that data during the design stage of a solar project, informs and significantly strengthens a solar project’s resilience to extreme weather events, alongside drastic changes in temperature.

Temperatures were recorded dropping significantly below long-term averages and historical data during Storm Uri, as seen in Figures 1 and 2.

Time Series data vs. TMY datasets

Inverter experts have highlighted the importance of considering extreme weather conditions when designing PV configurations, to ensure system reliability and prevent downtime.

They emphasize that extreme weather events (such as snow, freezing rain, and low temperatures) can cause moisture in the air, which can result in inverters turning off, and over-voltage issues due to lower impedance in cables and electrical wiring.

Solar cells, meanwhile, are temperature-sensitive, and can easily be affected by extreme weather conditions. However, extreme temperatures are usually not considered during the design phase of a solar project. The industry continues to rely on Typical Meteorological Year (TMY) datasets for the design of a project – causing blind spots in design strength, and potentially resulting in greater financial losses, as was seen in the aftermath of Storm Uri.

Figure 3 highlights the importance of utilizing accurate data, and not over relying on TMY scenarios in the design and planning of solar power projects. The stark contrast between the temperature values in these datasets – at the time of Storm Uri – can be seen by looking at the negative part of the graph.

The percentage of these negative values is close to zero, illustrating the magnitude of variation that can occur during extreme weather conditions, such as snowstorms. Figure 3 clearly depicts that only the Time Series data accurately captured the extremely low-temperature events (indicated within the circled values), while the TMY datasets could not account for such events, as they represent only typical probabilistic scenarios.

The varying shades of each color in Figure 3, which correspond to each dataset, highlight the accumulation

of data points – with lighter shades indicating a lower density of data. Once again, this emphasizes the rarity of such low-temperature values that can only be observed through time series files.

The importance of Times Series data in project design

The findings from figure 3 demonstrate the importance of utilizing accurate multi-year Time Series data for a more comprehensive understanding of the potential impacts of extreme weather events on solar power systems.

To strengthen a solar project’s design against such events, it is crucial to study and use accurate data to make informed decisions, particularly throughout the early design phase of solar power projects. Doing so helps determine the number of modules to connect in series and parallel to each inverter, and ensure that projects are built to withstand extreme weather conditions. Accurate historical temperature and irradiation values are also crucial for analyzing trends, predicting scenarios, and making informed decisions during the design process. Utilizing probabilistic scenarios, analyzing the long-term average, maximum and minimum values of temperature, and irradiance data unlocks better-informed decisions, which helpss to ensure that a solar project is built to withstand extreme weather and temperature conditions.

As extreme weather events become more common globally, solar investors need to begin planning for the unplanned. While the utility-scale solar industry already grapples with the elements (hail, in particular, has long posed a risk to the health of PV solar panels, and created situations in which farms are not meeting energy output expectations), asset managers can rely on digital solutions when intensifying storms cause operational issues.

The number of severe storms rose 40 percent in the 20-year period from 2000 to 2019, compared to the previous 20-year period, according to a United Nations report ; it follows that storms are increasingly affecting solar equipment. Last year, equipmentdriven underperformance resulted in roughly $2.5 billion in losses for the solar industry, with a sizable amount of revenue loss driven by physical damage to the PV module. The increase in production losses caused by severe weather is also a factor of solar projects getting bigger and more complex. Clear and fast communication and incident reporting to all stakeholders on the ramifications of damage is of utmost importance.

The answer to planning for unplanned weather damage is to lean on digitally-enabled workflows and robust data assets that expedite the identification and remediation of issues. This will also aid in recouping losses by speeding up the claims process for insurance or warranties.

In one recent instance, a major and unforeseen wind event occurred over the course of 24 hours on a 300+MW solar farm, causing significant damage to modules and tracking equipment. This is exactly the sort of weather event that can’t be planned for — a quick and coordinated response was key to getting the site operational again.

The first line of remediation involves implementing an inspection of the asset as soon as possible. Efficient, highquality data capture scans kickstart a process that leads to repair, warranty, or insurance claims, and minimizes exposure

for

to extended financial damages. Not all insurance policies allow filers to claim all lost production, so it is imperative that an asset is quickly back up and running again, and that parties gather a nearly real-time view of damages.

Pilots must be contracted and mobilized as soon as possible to survey the damage, and should coordinate inspections as soon

as conditions allow. It is ideal to inspect damage within a day or two.

Making full use of a data capture scan following an extreme weather event is dependent on ingesting and analyzing the data within a geo-reference digital twin (a comprehensive data model that acts as a clearinghouse for the entire history of the equipment). A key element in populating a digital twin is mapping serial numbers of all equipment on a solar farm, since these will be needed in the event of a warranty or insurance claim.

Field technicians can then use a mobile version of the digital twin while responding to a weather event, thus speeding up the process of locating and planning remediation of equipment issues.

In addition to storing serial numbers, commissioning scans are a foundational part of building an equipment record. Scanning panels prior to operations gives owners an idea of panel health prior to the onset of operations. Insurance providers and warranty holders look for this key data when reviewing a claim because they want to know whether

Raptor Maps /// raptormaps.com

or not the equipment was healthy before the weather event. For owners that build in severe weather-prone locations, having a digital twin from the start of operations would establish a baseline history of the equipment, and further speed up post-storm recovery.

Regular thermography scans are an ideal way to keep records of equipment for the life of the asset. Every time a scan is performed, asset managers build an equipment record and track its health over time.

The final step in responding to an extreme weather event is to use a software solution for warranty and insurance claims. This will help expedite the claims process by allowing teams to file applications with the needed data seamlessly, and with minimal guesswork. Solutions that allow for warranty holders and OEMs to review and collaborate on claims in a central platform also reduce resolution time by smoothing communications, and minimizing back-and-forths.

Most module warranty and insurance claims require the following information: specifics about the party making the claim and the site in question; a detailed written description of the damage; evidence of the damage, including photos and data; information about the type of module and serial numbers affected, and; specific accounting of the warranty start date. All of the above-named elements combine to expedite the claim process for both owners and warranty holders, saving time and money for everyone involved. As extreme weather events worsen, asset owners can begin planning for the unplanned, and continue to drive the world’s transition to a renewable future.

Unlocking Solar Potential on Unconventional Lands

Developers constantly face challenges in acquiring land, optimizing assets for increased production yields, and ensuring a lower LCOE to maximize revenues. Land scarcity affects developers who must purchase land at higher costs, which impacts their return on investment, slowing the pace of the energy transition.

Local opposition is also a growing and prevailing headwind to solar generation, often preventing towns from constructing utility-scale solar installations, and delaying state approvals and permitting processes. While measures such as the Investment Tax Credit (ITC) and the Inflation Reduction Act offer some relief, minimizing the impact on communities is necessary for accelerating the adoption of cleaner energy sources.

Locating solar generation facilities on landfills, uneven terrain with high slopes, or former industrial sites with polluted ground seems, on its face, like a natural solution to both the cost challenge and local opposition. Historically, this has not been the case. All of these terrains tend to come with a large share of technical and logistical complexity, which often erased any cost benefit of their use. These include difficult topographical conditions or contamination with hazardous materials that can necessitate additional measures to ensure safe construction and operation of solar installations.

Thankfully, due to the increasing cost of traditional suitable land, the cost calculus has started to change. Some 500 MW of solar capacity was installed on U.S. landfills by

The search for suitable land for solar development is a pressing issue as the demand for clean energy rises. Developers face challenges such as land scarcity, local opposition, and the need for cost-effective solutions. In this op-ed, we discuss these challenges, and present innovative solutions that can help unlock the potential of land previously considered unusable for solar generation.

the start of 2020, with a further potential for at least 63 GW on existing sites, and sites due to close by 2030.

Allowing the widespread use of these traditional unsuitable land types for solar generation will require effective solutions to reduce the cost of construction of untraditionally located solar generation. Some of these include:

Adaptable Solar Trackers

Solar trackers with adaptable designs can accommodate unconventional terrain, reducing the number of required foundations, and simplifying the installation process. This allows for easier implementation on various ground types, as well as superior adaptability to slopes. By reducing the number of foundations and civil works requirements, the overall construction costs and environmental impact can be significantly decreased.

Improved Assembly Processes

To address the shortage of skilled construction workers, and improve working conditions, the solar industry can adopt industrialized assembly processes for solar trackers. Onsite assembly workshops and assembly lines can reduce mounting time, helping to provide better working conditions for laborers, while ensuring efficiency and high-quality work. These standardized processes also maintain quality control, and enable easier project management.

Digitalization and Traceability

The adoption of digital tools in the solar industry can enhance the traceability of components and quality checks during the assembly process. Digital applications can help secure commissioning dates, manage project timelines, and maintain accurate records of each component and tracker, ultimately contributing to better project outcomes.

Minimizing Environmental Impact

Innovative solar trackers that minimize the number of piles and concrete beams required will reduce the environmental impact of solar farm construction. By causing less disruption to the natural habitat, these solutions also facilitate the integration of agrivoltaic systems that combine agriculture and solar energy generation. This approach can improve community acceptance of utility-scale solar farms, which, in turn, contributes to a more sustainable energy transition. Unlocking the solar potential on unconventional lands requires innovative solutions that address the unique challenges these sites present. As the demand for clean energy grows, it is essential for the solar industry to adapt and evolve, embracing new technologies and approaches that can overcome the obstacles associated with

developing solar installations on landfills, uneven terrain, and former industrial sites. By employing adaptable solar trackers, improving assembly processes, leveraging digital tools, and minimizing environmental impact, we can make significant strides in harnessing the untapped potential of these lands for solar energy generation. As a result, we will be better equipped to accelerate the energy transition, promote sustainable development, and secure a cleaner, more resilient future for all.

Solar module efficiency boost

The patented Solar Energy Optics (SEO) light redirecting film has been developed by Intelligent Control Systems Ltd. and provides an economical way to mitigate known losses in the edge area of HJT solar cells. By applying the SEO film to the inside of the HJT module front glass, light is redirected from the less efficient edges into the more efficient regions of the cells. The high performance is a result of the combination of two effects. The first one is an increased solar cell efficiency by minimizing edge recombination losses, while the second is an improved utilization of light from inactive module areas. Detailed optical simulation models of the solar modules and the SEO film have been constructed and validated with experimental data. The results show that the application of SEO film to a 120 or 144-cell module, with 2mm cell gaps and a white backsheet, can provide an efficiency boost of 2.6 % relative improvement, or two power classes. As an improvement on transparent bifacial modules or alternative to the gapless solution currently applied by some module manufacturers, the efficiency gains can exceed 3.5 %.

Stop Landfilling Batteries (Part 2)

How to reduce battery waste to near-zero

In Part One, we looked at battery waste reduction, from effective recycling programs and promising technologies, to closing the Recycling Gap.

Today, we’ll head upstream to where a battery’s waste footprint starts: design, raw materials, energy usage, and manufacturing. And you’ll see how some manufacturers minimize waste at every stage.

You’ll also discover the essentials to compare batteries to help slash your supply chain footprint and battery bill.

First, why reduce battery waste?

Electrification is critical to turn the tide on climate change and build a more sustainable economy. As the world embraces renewable energy, including solar, wind, and hydroelectric power, reliable storage becomes a critical buffer between fluctuations in supply and demand.

Less battery waste = less mining. This ensures more resilient supply chains, vibrant ecosystems, and ample raw materials for future generations.

Less waste protects our drinking water, soil, and air.

And less waste saves money: Efficient processes and materials insulate you from rising raw material prices; if wasted materials and wasteful processes are a bottomline expense for manufacturers, it’s clear who pays the final bill.

Any time you buy batteries, you’re voting with your wallet

Broadly speaking, there are two types of manufacturing:

• Open-loop manufacturing starts by mining raw materials from the earth, and ends with throwing out a used-up product. In the long term, it’s like trying to save money when there’s a hole in your pocket.

• Closed-loop (or “cradle-to-cradle”) manufacturing minimizes waste, and lets us reuse resources indefinitely.

Where do near-zero-waste batteries come from – and how do responsible manufacturers make them?

Start here: Reuse recycled materials wherever possible

Batteries have an environmental impact at every production stage, from raw materials and conversion, to transportation, scrap (material not in the final product), and recycling. Responsible battery manufacturers source recycled materials to decrease embodied energy and keep hazardous waste out of landfills. For instance, lead-acid and absorbent gel mat (AGM) batteries are 99 percent recyclable — and made using roughly 80 percent recycled materials. This closedloop minimizes mining and lowers production, retail, and societal costs.

Engineer waste out of the loop with resource-flow analysis

Twenty-first-century engineering considers a battery’s entire lifecycle, including reuse. Key steps include:

• Design for longer life and improved reliability in harsh operating conditions

• Optimize process efficiency

• Eliminate or decrease scrap

• Involve employees in waste reduction, including incentive programs

• Maximize recovery and recycling systems

• Recycle water and on-site materials

Finally, engineers can design batteries for easy assembly, repair, and disassembly at end of life.

Energy-efficient manufacturing reduces embodied carbon and protects you from energy price increases.

Battery production requires a lot of energy, and much of its environmental impact comes from powering heavy machinery. Companies that monitor their energy use,

and invest in energy-saving equipment, reduce their energy requirements. Charging alone can comprise 70 percent of a manufacturer’s electrical demands. Investing in an ultra-efficient battery formation system saved one company close to 5,000,000 kWh in 2020. And, because the new system precisely controls battery temperature, it improves battery performance and longevity.

Build renewable energy batteries with renewable energy

Companies should manufacture batteries using renewable energy (or fission power) to make them more sustainable. The more energy supplied through clean sources, the fewer fossil fuels need to be extracted and burned. Renewable energy reduces our reliance on non-renewable sources, mitigates climate change, decreases upstream waste, and creates good jobs.

Build batteries with wastereducing processes

- R&D includes CAD modeling, 3D printing, and extensive field testing. These enable engineers to solve common battery problems faster, and improve lifespan.

- More energy-storing “active material” + thicker metal lattices (grids) to hold it = more chemical reactions = longer life.

- Automation optimizes dozens of variables when mixing energy-storing paste, activating energy-holding chemicals during curing, and charging batteries during formation.

- Robotic assembly improves reliability and reduces waste. For example, Caston-Strap welding allows 3,940 more adjustments than manual welding –and eliminates partial welds.

- Quality assurance reduces manufacturing scrap – and prevents common failure modes Battery companies with extensive quality controls are more likely to catch mistakes early. Not only does this reduce manufacturing scrap, but it ensures batteries last longer before recycling.

Reputable manufacturers highlight their quality control procedures, including aerospace vision systems (robotic “eyes” that inspect critical parts), automated testing, and trained technicians with extensive checklists.

What’s next for Zero-Waste?

Support programs to end unregulated battery recycling and artisanal mining

In countries like the USA, strong regulations and responsible manufacturers protect workers and the environment:

• Manufacturing occurs in heavilyregulated facilities, with extensive safety training, and not in outsourced plants with lax laws or forced labor.

• Personal protective equipment like P-100 negative respirators guards against workplace hazards.

• A full-time, onsite registered nurse (RN) helps employees.

• Safety equipment and air/water filtration meet or exceed the latest federal, state, and local standards.

In contrast, mining and recycling are unregulated in some developing regions where there is a lack of proper safety oversight, equipment, and protocols. This leads to dangerous working environments, pollution, and community harm. Conscientious manufacturers and industry groups work with nongovernmental organizations (NGOs) and governments to demand an end to unsafe practices – and ensure equal access to modern equipment and safety measures.

Close the Recycling Gap –and push for universal battery recycling

To recap, lithium-ion batteries are collected 5 percent of the time – versus roughly 99 percent recycling for lead-acid and AGM batteries.

To close the Recycling Gap, the battery industry and government must:

• Support comprehensive policies and legislation for full recycling for all battery chemistries

• Create a robust collection infrastructure

• Invest heavily in recycling advances for emerging battery chemistries that are currently thrown out

• Ban landfilling

Together, these steps will improve batteries' environmental, economic, and social benefits. And they’ll increase our energy security.

Finally, you can choose low-waste batteries now from companies that preserve our resources.

The tips above will help ensure your batteries last longer before recycling –and drastically reduce waste.

By recycling, building, and selecting more sustainable batteries, we’re not just preserving our environment and lowering our operating costs – we’re protecting future generations and creating a more sustainable world.

Our transition to clean energy storage shouldn’t always start by digging a hole in the ground – and batteries should never end in a landfill.

Simple steps boost any RE battery’s lifespan:

• Size batteries for 50% Depth of Discharge (DOD) – and then compare options

• Store batteries in a dry enclosure with good ventilation and moderate temperatures

• Educate users on proper battery maintenance – all batteries need it for longer life

• Ensure proper battery installation.

When you compare battery manufacturers:

• Ignore marketing claims like “low-waste,” “green,” and “environmentally friendly”)

• Focus on verifiable facts like tons of waste recycled and Kilowatt-hours saved

• Look at their sustainability partnerships and awards. These often come from manufacturers’ power companies, industry associations, and the US EPA.

• Check out their brochures, press releases, and guides about sustainability and waste reduction.

• Ask to see their waste-reduction targets, including sourcing more recycled materials, improving recycling programs, and enhancing energy efficiency.

• Consider end-of-life and batteries that are more recyclable/recycled.

The Right Battery Can Avert Catastrophe

In this environment, the data center industry is susceptible to catastrophic storage meltdowns. Backup power from lead-acid and lithium-ion batteries counter sustainability efforts. Worse, the battery technologies can contribute to the meltdown with failures or fires. Sodium-ion battery technology is a more sustainable, and inherently safe solution for data centers and any mission-critical business.

Traditional batteries can compound problems

The many possible causes of a data center outage include hardware failure, software bugs, cybercrime, and natural disasters. The resulting downtime and data losses are always devastating. Preventing these meltdowns requires robust and reliable backup power. Without it, servers and associated IT systems can shut down improperly, corrupting or losing data, damaging hardware, or simply disrupting the network. Data centers are always equipped with uninterruptible power supply (UPS) systems that smooth fluctuations in incoming grid power, and support the data center load for a short time in the event of a power outage – until backup generators kick in.

Lead-acid batteries have been the traditional choice to power these UPS systems. This meant sophisticated, sleek, modern data centers were relying on stacks of bulky, heavy, often unreliable car batteries. Lead-acid batteries also pose a risk of overheating when overcharged or discharged too rapidly, a necessary function of a UPS system. Hydrogen gas can build up and ignite, causing an explosion, and corrosive sulfuric acid can leak out if lead-acid batteries are damaged or cracked. Not an ideal environmental or safety choice.

Lithium-ion batteries for UPS systems improved upon some of lead-acid’s problems, but the tradeoff was a high risk of fire. Lithium-ion batteries are far more prone to catastrophic failure than lead-acid batteries; they can be induced to thermal runaway more easily. When these batteries overheat and catch fire or explode, they can cause severe damage to the storage devices, as well as potential loss of data (not to mention harming humans near the site). Thermal runaway can be caused by overcharging, physical damage, exposure to high temperatures or humidity, and manufacturing defects.

Lithium-ion batteries are believed to have contributed to many data center meltdowns in the last five years, including Saint-Trivier-sur-Moignans and Strasbourg in France, and another in South Korea. Complicating matters further, the fire risk associated with lithium-ion batteries led to understandable – yet, still onerous –regulations around the storage and transport of these batteries. It’s no surprise that many data center operators have been slow to embrace lithium-ion batteries. When uptime is everything, the risk with lithium-ion is just too great.

Sodium-Ion batteries eliminate the risk of catastrophic meltdowns

Sodium-ion batteries are a safer, more sustainable alternative to traditional batteries. Not only are they made of abundant raw materials that require no conflict minerals, but they also are four to five times more power-dense than lithium-ion or lead-acid batteries, and far safer.

Electrode chemistries, like Prussian blue, take a man-made dye and turn it into a completely safe, porous energy storage medium. These pores allow immediate discharge and full recharge in under a quarter-hour. This reduces the wear on backup generators and, more importantly, their carbon emissions, since the sodium-ion battery will be charged and prepared for back-to-back power events faster. Their chemistry allows sodium-ion

As temperatures lurch up and down, storms rage, and wildfires burn, the aging United States power grid remains vulnerable. Outages caused by extreme weather cascade across industries, costing the U.S. billions each year.

batteries to perform this rapid discharge/ recharge cycle tens of thousands of times before replacement is needed. Thanks to their long service life, and because they minimize the role of the generator, sodium-ion batteries can help data centers move toward their environmental and social governance (ESG) goals.

Where sodium-ion batteries really stand out is safety. Sodium-ion batteries are safe, nonhazardous, and cannot be induced to thermal runaway. They will not catch fire or explode, even if exposed to direct flame or punctured. This is a massive risk reduction for data centers. Sodium-ion batteries perform equal to or better than traditional alternatives by every measure, and entirely without risk of fire or explosion. These batteries can be shipped fully charged by ground or air (unthinkable for lead-acid or lithiumion) thereby accelerating system start-up. The major takeaways for data centers, especially as they deal with increasingly extreme and frequent weather events include:

• Able to handle temperature swings – Sodium-ion batteries can operate in a wide range of temperatures (-58°F to 122°F) and will not be induced to thermal runaway by operating in very high or low temperatures.

• Safer, super-fast discharge – Sodium-ion batteries can immediately discharge without risk of overheating, and without settling or thermal waiting.

• Will not worsen a meltdown – If the worst should happen (i.e., a data center floods or experiences a fire) sodium-ion batteries will keep working as long as they can. They will not immediately shut down, nor will they ever catch fire or explode.

• Lighter overall footprint –Measuring the total cost of ownership, sodium-ion batteries provide excellent value, and contribute significantly to ESG goals. They require replacement less often, are made from sustainable, non-conflict materials, and reduce emissions from generators. Data centers can no longer avoid extreme weather and the associated outages and catastrophic meltdowns by choosing a “safe” geographical location. Their operators should plan for

weather-related outages as a “when,” not an “if.”

Sodium-ion batteries can power UPS systems better than traditional battery technologies, removing the major risks of lithiumion and lead-acid. They are the safer solution.

Jack Pouchet is the Vice President of Sales and Marketing for Natron Energy. Jack works closely with major OEMs, large Telecom, and data center owners and operators, BESS/ESS integrators, industrial power users driving towards decarbonization, and leading mission-critical engineering firms to help define, architect, and create opportunities for advanced battery and power technologies that improve day-to-day business and operational efficiencies. Jack brings over twenty years of related OEM power supply, power generation, distribution, and power product sales and marketing experience to Natron, giving him a unique, end-to-end perspective of the entire AC and DC power path.

Powering Up in Harsh Conditions

Major weather events such as hurricanes, strong winds, and ice storms are the primary reason for long-term power outages. In highly-populated areas, frequent power outages (often referred to as brownouts or blackouts) are a recurring phenomenon that occurs when the power grid cannot support increased demand. Clean energy, such as solar or wind power, has proven to be a reliable and sustainable solution to meet the world's growing energy needs. However, alternative energy sources must prove resilient against extreme weather conditions, harsh climates, and challenging locations if they are to ensure survival and success. Several deployment and technology strategies can help achieve this goal.

Energy distribution and storage

Distributed energy is a strategy to decentralize power generation and storage from the current centralized transmission and distribution lines system. Centralized distribution remains the norm in today’s world, but it's also more susceptible to being impacted by natural disasters, which can lead to catastrophic overloads.

As we look at aging transmission lines, especially in rural areas, the impact of severe weather events can have devastating effects on those in the service area. Hundreds of thousands of homes and businesses are often left without power for indeterminate lengths of time. In fact, according to the US Energy Information Administration, businesses and individuals experienced over eight hours of power interruptions in 2020 alone.

During some emergencies, communities are told to shelter in place in their homes or businesses. Investing in a residential or commercial battery system can prove invaluable in these scenarios. Battery or energy storage systems enable a home or business to become its own ecosystem of energy generation, allowing people and communities to brace for further natural disasters while creating resilience for their homes and communities until grid infrastructure is upgraded.

Harnessing and managing captured power

After determining a strategy for energy distribution, the next step is to deploy energy storage effectively and consistently. Energy Storage Systems (ESS) can provide power during low renewable energy production or grid disruptions. Batteries charged with energy from renewable sources, the grid, or backup generators allow for the mining and storing of energy that can be used when there is a critical power shortage. These systems can be tailored to a particular region's outage history, and the duration of that stored power can be sized appropriately to support the most critical loads.

In recent years, interest in power independence and energy alternatives has grown due to failing power grids. Additionally, frequent severe weather has led to increased power outages across the United States. Federal data found that in 2020, more than 180 large and sustained outages occurred; in 2000, there were fewer than two dozen major power outages. These factors are causing a surge in demand for energy storage systems.

Combining charging resources with hybrid systems can provide more reliable power than single-source systems. For example, solar and wind can charge batteries in inclement weather. Then, once the power restores, these same systems are connected to the grid, allowing the batteries to recharge quickly.

The importance of safety

Prioritizing safety is paramount when considering resilient power. Energy storage, battery chemistry, and manufacturing processes are drivers of protection for a battery system, especially when installed in homes and businesses. Multiple types of battery technologies can be used for energy storage systems. Specifically, lithium-ion batteries are popular for many applications due to their high energy density, long cycle life, and low self-discharge rates. However, studies have shown that Lithium Ferro Phosphate (LFP) leads the industry in safety. LFP batteries do not contain cobalt — a hazardous material that contributes to thermal runaway, toxic fumes, and the risk of fire and explosion.

Many consumers do not realize that most lithium-ion batteries contain cobalt. When looking into battery companies and products, it’s essential to look for ones that have met and exceeded minimum offgassing standards, and eliminated the risk of fire and explosion through UL 9540A safety testing. These are often the best batteries for residential and commercial applications as they don't generate significant heat, don't act as an accelerant when exposed to flames, and can be used safely indoors without cooling or ventilating.

Building a more resilient future

As the world transitions to clean energy, it is essential to invest in resilient strategies to ensure its survival and success. Clean energy can survive and thrive in extraordinary weather situations, challenging locales, or punishing atmospheres by utilizing a combination of different deployment and technology strategies.

Effective energy solutions can create safe and long-lasting resources for people to charge their phones and computers, check in with loved ones, and have heat, light, and a safe place to stay when the rest of the electric grid has failed. Distributed energy, energy storage, hybrid systems, and prioritizing safety are some of the most effective strategies anyone can use to ensure the success of clean energy during challenging times.
