EDITOR'S NOTE

NEWS BITES

H

ow many apps do you have on your phone? If you have to scroll through more than two screens to find the icon you need, you’re not alone. (Also, if your battery dies more quickly lately, you’ll want to check your settings; you should able to prevent the battery from wasting power managing apps you rarely open.)

Traditionally, the IT industry concerned itself with developing really useful applications aimed at helping us get the most out of our smart phones. While most apps don’t interest me, I recognize their value for other (and more organized) people. You probably already have map and calendar apps on your phone, plus a few more frivolous ones like games or news feeds. I’m betting, however, that you may not have some of the more niche offerings; a quick online search netted me a short list of some of the lesser recognized apps. These include the intriguingly-named “Carrr Matey”, which uses a pirate voice to remind you where you parked your car, and “Run Pee”, which could come in handy by letting you know the best time in a movie plot to run to the bathroom so you won’t miss any important action. My personal favorite: “Demotivational Pics”.

Years ago, I used to marvel at the creativity involved in creating an app. How do people figure out who to help do what? I also used to wonder who had the time for such a big job; it can take anywhere from 200 to 1500 hours of development before an app is ready for its debut on Google or Apple formats. Once you’re ready to introduce the world to your new and different idea, you’ll be vying for competition with upwards of 350 million available apps on offer to the general app-loving public. (After months of lockdown-induced boredom, that number may be on the low side.)

This brings to mind a recent app that’s getting an inordinate amount of ad time, if the repeated interruptions to my television and radio intake are anything to go by. “Clime”, presumably short for “climate”, describes itself as a personal weather assistant that updates you with complete and real time weather updates, including live NOAA radar. No doubt there are similar apps on the market, though I admit being impressed hearing the announcer correctly pronouce the acronym for the National Oceanic and Atmospheric Administration (“Noah” like the ark, by the way, not “N.O.A.A.”).

On the other hand, who besides weather nerds needs regular access to NOAA radar? Growing up, I considered the topic of weather the purview of the older crowd, like when your grandparents ask you about the weather so they can tell you about the weather where they are, or when casual acquaintances comment on the weather as a safe topic for a quick conversation.

Our industry relies heavily on this data to manage millions of dollars of clean energy equipment so we can plan for possible damage, and quickly ramp production back up the moment we’re given the all clear. While hurricanes are obvious concerns for anyone within their path, lightning is less of a worry for most people; yet, each of these phenomena can set an insurer’s teeth on edge. Maintaining such valuable investments is a huge business, and the stakes are high, both financially and in terms of reputation; no one wants to see their misfortune turned into a disaster meme. Public support for the adoption and expansion of green energy demands continued demonstration of the reliability of clean energy technologies. If we are expected to wean ourselves from oil, we must match and exceed the dependable performance our energy consumers count on every day.

“It never rains in southern California.”

PV electricity charges new sky jeep

The UK’s first electric aircraft charging point has been installed at the East Anglian airfield, courtesy of NUNCATS – a Community Interest Company (CIC) that aims to provide a dependable lifeline for some of the world’s most remote communities via electrical light aircraft. This unit, installed by Renenergy for NUNCATS (which stands for No Unnecessary Novelty, Community Air Transport Systems), is not only the inaugural electric plant port in the country, but is also Europe’s first solar-powered electric aircraft charging point thanks to the 33 Q.PEAK DUO L-G8 Q CELLS solar modules installed on top of the hangar. Q CELLS’ Q.PEAK DUO L-G8 425W modules provide solar power to a specially adapted Zenith 750 aircraft, or ‘electric sky jeep’, which has begun a series of solar-powered sorties above the East Anglian skies to demonstrate how sustainably powered light aviation can really make a difference in many of the most remote parts of the world.

For Q CELLS, this partnership is an opportunity to demonstrate the exceptional reliability and efficiency of its solar modules. The Q.PEAK DUO L-G8 module series guarantees high performance, a high yield per surface area and an efficiency rate of up to 20.3%.

The modules are made with Q CELLS’ passivation technology Q.ANTUM, which helps them deliver longterm yield security and long-lasting, low maintenance performance under a 25-year performance warranty.

NUNCATS’ co-founder, Tim Bridge, hopes that the installation, which is based on an adapted car port developed by Renenergy, can serve as a launchpad for the further electrification of the skies, powered by solar energy. The prototype aircraft currently charged

by Q CELLS modules boasts a 30kWh battery, which can power a 30-minute flight, the base minimum for efficacy in rural parts of the world.

Mission to advocate for greener aviation

A team of pilots will achieve their circumnavigation with net-zero carbon emissions, mainly using Sustainable Aviation Fuel (SAF). Diamondo Earthrounding, a non-profit initiative, driven by a team of nine young aviators, departed Zurich, Switzerland in a Diamond DA50 RG 5-seater aircraft on January 2nd, 2022. Flying in an easterly direction to visit multiple airports, cities, and sustainable initiatives with a mission to connect worldwide projects for sustainable aviation, raise awareness of sustainable technologies and how to utilize them, as well as aim to accelerate aviation’s path to net-zero carbon emissions. Diamondo's founding partners and pilots Robin and Matt believe one of the main pillars for green air transport is Sustainable Aviation Fuels (SAF).

During the circumnavigation, and amongst other green initiatives, the crew are therefore visiting, documenting, and reporting from sites critical to the production of sustainable aviation fuel (SAF). In addition to raising awareness for sustainable technologies, the team also promotes ways of investing in them on a voluntary basis. The Diamondo Earthrounding website offers guidance on how airline passengers, business aviation customers, and private pilots can fly with netzero emissions. Diamondo Earthrounding aspires to motivate more people to use these voluntary platforms and help accelerate aviation’s path to reduced emissions.

TOP STORY

Navigating the Era of Disruption with Digital Infrastructure Solutions

by Michael Martinez

If the past few years taught us anything, it’s that disruption is the new normal.

Whether it’s supply chain interruptions, new COVID-19 variants, changing cybersecurity attack vectors, or increasingly unpredictable and more damaging extreme weather, the barrage of challenges and threats facing businesses is – unfortunately - here to stay.

To solve these challenges and successfully navigate this new era of disruption, organizations need to move beyond piecemeal solutions.

Regardless of industrial sector, now is the time for companies to take bold measures and implement holistic solutions built on secure, next-generation technology that’s flexible enough to address current operational factors and any new curveballs thrown their way.

The rise of automation technologies enabled the development of Industry 4.0, a new phase of the Industrial Revolution that leverages automation and machine learning to help create more efficient and productive work environments in sectors like manufacturing. These technologies provide increased connectivity and real-time data, enabling organizations to make better decisions and see solutions to existing problems that were previously unfathomable.

Companies need to prioritize creating a modern workplace with the newest technology and automation systems to optimize facility operations. Many companies who brought operations up to Industry 4.0 levels are realizing the benefits of digital infrastructure solutions that deliver data-driven business intelligence, and enhance operational and financial performance.

Also key to achieving benefits of the next generation industrial environment is incorporating and supporting underlying technology infrastructure designs that prioritize an interoperable system, data driven software-based automation, and the integration of energy and automation.

In the fast-changing world of industrial automation, companies must focus on implementing innovative technologies to gain a competitive advantage and better position themselves as a leader in their marketplace. A recent Deloitte survey1 found that, while nearly 100 percent of industry executives understand the urgency of a digital transformation, only 14 percent are highly confident in their company’s ability to implement it.

There are three key benefits organizations can achieve by integrating industrial automation technology with their manufacturing infrastructure: 1. Remote management access Gone are the days of facility managers having to do it all by themselves. Digitizing facility controls and machines enables remote management capabilities that provide data-driven insights. Through system sensors and monitors, users can aggregate data into insightful and actionable reports to inform decisions on operational or business changes.

2. Shorter and fewer downtimes Preventive maintenance is key to avoiding downtime, which can be costly in terms of both profits and reputation. Industrial

automation systems can monitor operations and alert users in real-time of potential issues, enabling professionals to inspect the situation before it escalates.

3. Reduced energy spending and consumption Facility managers are constantly asked to look for new ways to optimize operations to cut spending and reduce energy consumption. Industrial automation software is an easy way to address both by providing managers insight into daily operations, giving them a holistic view of where to implement efficiencies and optimize energy usage.

While the manufacturing industry is pioneering adoption of digital technologies and IoT-based applications, others are more reluctant to implement such innovation, either due to older workforces with less digital expertise or skepticism surrounding the need to improve current operations. No matter the reason, it’s time to look past that and update internal systems to better protect companies and customers.

Companies cannot afford to stay in an analog world; adopting digital infrastructure solutions are critical to help securely navigate ongoing disruptions. However, digital modernization and automation comes with risks and potential vulnerabilities that organizations need to understand and mitigate.

Bad actors have long targeted U.S. utilities, but with cyberattacks on the rise and showing no signs of slowing down, companies need to proactively work to safeguard potential areas of vulnerability.

The increased targeting of critical infrastructure means sectors that don’t have mature cybersecurity programs, like water and wastewater, are finally taking concerted efforts to better protect themselves, including leveraging intel and best practices from the federal government and utilizing more security processes and technologies.

That holistic approach to cybersecurity – addressing people, processes, and technologies

– is crucial. Given the growing IT-OT convergence, it’s more important than ever that organizations adopt flexible, vendor-neutral solutions for the most effective security. Digital infrastructure solutions can’t alleviate all issues for companies, but the system can be a mitigating force.

An essential factor in boosting security is addressing the people – every employee has a role to play, and leadership needs to create a culture of cybersecurity so it’s taken seriously. This starts with establishing a set list of security policies, guidelines and practices for employees to understand.

All team members – even those in positions that traditionally didn’t require a cybersecurity briefing – should be regularly briefed on both company cyber policies and best security practices. It only takes one employee to accidentally click on a phishing email and infect their network, so all employees need to fully understand their role in helping sustain a secure and protected network.

The bottom line is that our industrial sector cannot afford to sit still. The new era of disruption is here to stay, and digital infrastructure solutions hold a major key to business resiliency and sustainability. Adopting next-generation digital infrastructure solutions can help better protect, and even future-proof, company operations by staying ahead of threats in whatever form they take.

WIND POWER

New York Bight

An offshore wind milestone

by Ari Benkler and Doug Pfeister

T

his past February, the Bureau of Ocean Energy Management (BOEM) conducted Atlantic Wind Lease Sale 8 (ATLW-8), auctioning six offshore wind lease areas in the part of the Atlantic Outer Continental Shelf lying between New York and New Jersey known as the New York Bight. Due to intense developer competition, the sale brought in $4.37 Billion of bid revenue to the US treasury in the highest-grossing offshore wind lease auction ever, cementing offshore wind’s status as a flagship generation asset of the future.

Turning their focus to the economic opportunities resulting from the energy transition, policymakers put in place strong policies catalyzing developer participation in the market. This policy interest, combined with developers’ prospects of winning early incumbent positions in renewable US offshore energy, led to supercharged industry competition for seabed leases.

The US offshore wind industry has reached an inflection point: ATLW-8 was BOEM’s highest-grossing offshore lease auction across resources, including oil and gas. All told, the domestic industry now claims two operational demonstration-scale projects, nearly 15 GW of capacity with a secure route to market, and 25 GW more in development.

By furthering decarbonization and economic policy goals, providing value for developers and investors, and bringing jobs and billions in regional economic benefits, offshore wind is charting a path to green commercial scalability that will be vital across many areas of the energy transition.

Looking beyond the auction, the real economic gains to developers, policymakers, and the regional economy will accrue through competition over which projects within the new lease areas secure a route to market, also called offtake. Seabed rights alone are hugely valuable, as the New York Bight auction shows, but most project value is realized when offtake is secured.

Because confidence in offtake is increasing, the gap between lease prices for sites with no current offtake and prices for more mature portfolio acquisition - including assumption of offtake contracts - is decreasing. Recent acquisitions of portfolios in more advanced development have ranged between $400 million and $1.1 billion, almost identical to the ATLW-8 lease price range, with 20-60 percent of portfolio offtake secured in each deal. This route-to-market clarity has been vital to the industry’s regional takeoff, and owes massive thanks to New York’s and New Jersey’s pioneering leadership in transparent and multi-year planning for offshore wind procurement.

For developers, an offtake agreement guarantees a future stream of revenue tied to the project’s energy production through New York and New Jersey’s Offshore Renewable Energy Credit (OREC) mechanisms. Combined with the sales of power directly onto the grid, ORECs provide developers the necessary revenue certainty to proceed to move a project from high-level planning to more advanced development and eventually construction.

For state policymakers, the OREC solicitation is critical because it requires developers to submit data, plans, and competitive terms that help policymakers select the best projects to advance the states’ climate, industrial, and economic goals.

10

2022 MAY• JUNE /// www.nacleanenergy.com

For the regional economy, offtake certainty sounds the starting gun for the process of developing contractor relationships and signing supply contracts that will deliver the physical components, services, and labor necessary to plan, permit, and construct an offshore wind project. Local suppliers and labor unions in industries like steel, electrical components, ports, and vessels stand to benefit: in her 2022 State of the State, New York Governor Kathy Hochul projected that the five offshore projects already under contract with NYSERDA would alone bring more than 6,800 jobs and over $12 billion in economic benefits to the state.

New York’s next OREC solicitation is going forward this summer. By moving fullsteam ahead, New York is ensuring a consistent stream of work for the region’s smalland medium-sized suppliers. For these suppliers to grow into a robust regional supply chain capable of servicing a mature offshore wind industry, a steady drumbeat of new projects must provide critical certainty about future revenue; New York’s drive to advance projects quickly helps provide that certainty. This is in keeping with the state’s overall strategy for the green economy: Governor Hochul’s 2022 State of the State speech included a new $500 million public matching fund to augment economic benefits owing to supply chain investments that have been guaranteed by developers.

New Jersey chose to wait until early 2023 to allow new entrants additional time to prepare their OREC bids. More bids mean more intense competition and downward

price pressure. Overall, the OREC price, or payment per MWh to the offshore wind project, may well decrease due to the benefits of this intense competition and any potential technical advantages that may lie in the newly leased sites. According to the New Jersey Board of Public Utilities, the state’s economic benefits regime has seen awarded projects commit between $400 million and $1.3 billion in direct economic benefits with up to $2 billion per project in estimated indirect benefits.

Looking to future lease auctions, competition for seabed rights is likely to remain intense, especially where the route to market is well-defined. In the New York Bight, large lease areas near large electric load and nation-leading demand for renewable energy has fueled especially intense competition.

As shown by the 25 qualified auction participants, a huge number of global developers are interested in building US offshore wind projects. On the demand side, state policy frameworks like renewable portfolio standard carve-outs for offshore wind, Integrated Resource Planning, and the federal 30 GW by 2030 goal ensure a robust pipeline of demand for future offshore wind generation.

With a strong supply outlook as global developers jockey for position in the US market and ever-growing demand from state, federal, and utility plans and policies, the path forward for offshore wind looks increasingly certain.

This certainty, in turn, is key to the benefits all offshore wind stakeholders are confident the industry will bring about: efficiently moving the grid away fossil fuels, realizing substantial local and global environmental benefits, and stimulating the green energy economy with jobs and economic growth.

Who Are They?

Intro: The recently held auction for six leases in the New York Bight was expected to be hotly contested.

Global developers, investment consortiums, and energy companies have sought strategic partnerships with one another to maximize their competitive chances. Below are listed the organizations behind the winning bids.

Entity: Bight Wind Holdings Land parcel: OCS-A 539 (winning bid $1.1 billion) Winners of the largest lease available at this auction, Bight Wind Holdings, is a joint venture between RWE, Germany's largest power producer, and National Grid.

RWE owns roughly 9 GW of operational renewable assets globally, including 2.5 GW of offshore wind. National Grid’s participation in the project is likely to facilitate ease of interconnection, further de-risking the project.

Entity: OW Ocean Winds East Land parcel: OCS-A 537 ($765 million) OW Ocean Winds East LLC is a joint venture between Portugal's EDP Renewables (EDPR) and France's ENGIE. EDPR was an original investor in the Massachusettsbased Mayflower Wind project, in which the Ocean Winds partnership now retains a 50% stake. EDPR Americas is also one of the biggest onshore developers in the nation. As of December 2021, ENGIE, one of France’s largest energy companies, owned a 2.3GW operational onshore renewables portfolio in the US. Entity: Attentive Energy LLC Land parcel: OCS-A 538 ($795 million) Attentive Energy is a subsidiary of TotalEnergies Renewables USA which began in 2021 as a JV between Total and EnBW, a large German developer. Total is one of the world’s oil and gas “supermajors” and has moved aggressively towards investment in the renewables space. Total has acquired or begun development on nearly 4 GW of US projects, part of its global aim to develop 35 GW of renewables by 2025 and achieve carbon neutrality by 2050.

Entity: Atlantic Shores Offshore Wind Bight LLC Land parcel: OCS-A 541 ($780 million) Atlantic Shores Offshore Wind Bight LLC (ASOW) is a joint venture between Shell New Energies US LLC and EDF Renewables, a major French electricity provider. ASOW has already won offtake for its original site, along the northern part of the New Jersey shore, through New Jersey’s previous OREC solicitation. Due to its experience, existing investments, economies of scale, and success in competing for offtake, ASOW is expected to be among the most compelling OREC bidders for subsequent procurements.

Entity: Invenergy Wind Offshore LLC Land parcel: OCS-A 542 ($645 million) Invenergy Wind Offshore LLC is led by project sponsors Invenergy, an established US onshore wind developer, and energyRe, a new development group. The project is funded by a consortium of investors led by the project sponsors which further includes Blackstone Infrastructure Partners, the Quebec public pension fund CDPQ, FirstLight Power, and Ullico Infrastructure Fund.

Entity: Mid-Atlantic Offshore Wind LLC Land parcel: OCS-A 544 ($285 million) Mid Atlantic Offshore Wind LCC is owned by Copenhagen Infrastructure Partners (CIP). As one of the global developers with a meaningful US incumbency advantage, CIP was involved with Avangrid (Iberdrola) in the development of the first US utility-scale offshore wind farm, Vineyard Wind. CIP also retains seabed rights to OCS-A-522, a Massachusetts lease area capable of selling power into New York as well as New England, that is expected to compete in upcoming and future procurement rounds.

WIND POWER

Lightning

When avoidance is not an option

by Søren F. Madsen

S

ound familiar? Lightning is sometimes treated as an issue that only affects some turbine parks. But the reality is different.

Lightning is one of nature's most common – and most destructive – spectacles. Around the world, there are over 3,000,000 flashes every day. And with the climate changing, we are seeing even more lightning events in areas that have never experienced lightning strikes before.

Tall structures like wind turbines are prone to being struck by lightning. This becomes even more profound as turbine sizes increase. Yet, being struck is just one effect of the phenomena: wind turbines also initiate lightning flashes themselves, which is known as upward lightning. And with the ideal wind turbine sites gone, developers and owners are forced to erect turbines at ever more remote locations with suboptimal wind classes, microclimates, and terrains.

When you combine the general lightning phenomena with new lightning patterns due to climate change, increasing turbine size, turbine-triggered upward lightning, and suboptimal (and remote) terrains, it becomes clear: avoiding lightning is not an option. But preparedness is.

Lightning damages, related repairs and downtime are major cost drivers in the wind sector. Onshore wind owners might be lucky to get a bill for “only” tens of thousands of US dollars; offshore, those costs could start at a six-figure scale. Materials, service, personnel, mobilization, logistics, loss of power production, weather delays – all these add to the costs for wind park owners and operators. With such an extensive effect, lightning preparedness offers a simpler and cheaper way out.

Preparedness centers around four main aspects: 1. Assessing lightning risks on site.

2. Designing and building robust blades, lightning protection systems (LPS), and conductive components.

3. Verifying the LPS performance by modelling and lightning testing.

4. Monitoring the LPS performance in the field.

These complement each other in a way that enables owners and operators to be fully prepared to what comes next: lightning.

Lightning strikes vary across a single wind farm due to local topography and weather conditions. Whether it is onshore or offshore, understanding the lightning risks at a future or existing wind turbine site is crucial. When developers carry out a site assessment prior to installation, they get to know the expected lightning exposure, severity, and occurrence for the specific wind farm. This helps them to find an optimal weather window for turbine installation well in advance, lowering the risks for installation delays that otherwise lead to significant costs.

Engineering teams can also use the site assessment data during their blade- and lightning protection system (LPS) design. By integrating the local lightning risks into their models, they can make the turbine components and LPS more robust against lightning damage. And by knowing the individual risks for each turbine at a single park, they can customize the LPS even further to maximize protection and decrease costs.

At an already existing turbine park, lightning assessment addresses other

aspects, including how to prioritize an LPS retrofit or lightning measurement campaign, when to schedule retrofitting based on lightning seasons, and why are there static precipitation issues.

Lightning site assessment gives manufacturers, developers, and owners the crucial data they need for turbine and LPS design, and installation and maintenance planning – all of which help minimize lightning damages, expenses, and delays both in the short- and long term.

When it comes to the damages, manufacturers play a crucial role. As lightning is unavoidable, they have two goals in mind: first is making sure lightning strikes the turbine at the right place, and second is leading the current from the strike point down to the earth without causing any troubles along the way. Numerical models and computer simulations are essential to achieve these.

Models and simulations allow engineering teams to find the lightning attachment points, outline the risks of lightning strikes across the whole turbine structure, see how the current travels within the blade and across turbine components, or visualize side flashes, thermal damages, or any other indirect effects within the turbine. Feeding these results (and the ones from the site assessment) back to the blade and LPS designs - and adjusting them along the way - ensures an efficient and robust process that minimizes failures and delays upon prototyping and product testing.

When manufacturers get to the lightning tests, they have a lot to consider: Choosing the right laboratory (accredited? Independent?); the type of lightning tests (standard setup or customized? High voltage or high-current tests?); and the turbine component to be tested (full-scale blade or just the tip? What about nacelles or blade bearings?). One thing is certain: all tests must be according to the international standards.

Why? Because it allows a smooth and fast(er) certification of the new LPS, and ensures the developers and owners that the system will protect their turbines.

Lightning preparedness does not stop here; the LPS needs to be monitored after installation. Without monitoring, the owners and operators will not see if something needs to be replaced or repaired, or if the LPS is truly compliant to the real lightning conditions on site. You’ll find different monitoring solutions on the market, a few of which can even gather real-time data on the lightning characteristics and turbine conditions. With these, owners and operators can maximize their turbines’ performance, plan maintenance and inspections, and keep their turbines fully protected against lightning damages.

Lightning will not go away, and it cannot be avoided. Playing it safe costs less than those six-figure repairs. If the wind sector wants to boost the green transition, lowering costs and risks is key. It will not only help their own budgets (and reputation) but will shift public opinion to help push legislation, regulation, and investment in the sector forward.

“Lightning is not an issue at our site.”

“We have never had any lightning at our wind farm, why would we start having them now?”

“Chances of a lightning strike are low, so we prioritize other things.

We will just go ahead planning the installation and hope for the best.”

WIND POWER

Power Your Wind Energy Safety with Electrical Testing

by Richard Rivkin

It is no secret that wind energy workers are exposed to several different work-related hazards. Whether constructing new turbines, refurbishing existing units, or performing general work around windmills, it is imperative for their employers to assess all the potential threats in order to implement optimal work practices and procedures, including the use the personal protective equipment (PPE), while also ensuring the PPE is safe and effective for its intended use.

Electrocutions and exposure to arc flash are among the top safety and health concerns. At any given time, wind energy workers are working on or around generators, control panels, slip rings, batteries, capacitors, transformers, collector systems, substations and test equipment. Or they may be performing activities such as IR inspections with equipment open, racking in and out of circuit breakers, inserting or removing energized equipment, LOTO, fault finding and testing in an energized sate.

All of which pose significant electrical safety risks. A proper arc flash hazard analysis and shock risk assessment will identify the exact controls that should be in place (engineering, mechanical, human, or otherwise). From there, the appropriate electrical safety program and PPE can be determined.

The NFPA, along with the Occupational Safety and Health Administration (OSHA), mandates and enforces safer electrical work practices under the NFPA 70E standard. Wind energy workers are touching exposed conductive parts, which makes their hands highly susceptible to arc flash and electric shock.

OSHA rules require the use of rubber insulating gloves (electrical gloves) when even the smallest probability of contact with 50 volts AC or higher exists.

Electrical gloves are the only protective gear designed for constant contact with, and protection from, energized conductors and equipment. All of the other items are designed for protection from accidental, incidental, or brush contact.

Arc-rated work gloves alone provide no protection from voltage.

Electrical gloves are an essential element in protecting workers exposed to high-voltage currents. Shock protection is the primary benefit. However, electrical gloves also provide significant burn protection in the event of an arc flash.

According to the OSHA 29 CFR 1910.137 standard, electrical gloves must be rated for the voltage to which a worker will be exposed (phase to ground or phase to phase) and marked to indicate their rating. For in-service use, the maximum use voltage must be above the actual exposure, but it is important to take note of the proof test voltage as well. All electrical gloves are tested by the manufacturer at the specified proof test voltage. Manufacturers also perform a dielectric breakdown test at an even higher voltage to validate the dielectric strength of the rubber material. The result

14

2022 MAY• JUNE /// www.nacleanenergy.com

is a significant margin of safety between the test voltages and the maximum use voltage. Each specific hazard assessment will help in determining which class of gloves is appropriate for the application. Voltage protection is broken down into the following classes, and each class of gloves is clearly marked with the maximum use voltage on the color-coded label: It is important to note that the ASTM standards also include DC test and maximum use voltages, as wind energy workers could be exposed to both AC and DC. But wearing the appropriate personal protective equipment alone is not enough. OSHA regulations and ASTM standards also require regular dielectric testing of in-service electrical gloves in order to maintain compliance and ensure the products’ safety and integrity when exposed to a wide range of voltages.

ASTM Manufacturing and Acceptance Standards mandate the

testing of rubber insulting equipment by the manufacturer or supplier prior to the first delivery to the end user. Users also have the option of performing or requiring an acceptance test upon receipt of the goods and prior to placing rubber insulating gloves into service. Once placed into service, the periodic re-test intervals should be based on work practices and test experience. For gloves, ASTM F496 states that the interval shall not exceed six (6) months except for industries that utilize insulating gloves as precautionary protection, in which case the maximum interval may be increased to nine (9) months. However, do not place rubber insulating products into service unless they have been tested electrically within the previous twelve (12) months. These inservice re-test intervals are the MAXIMUM permitted and in addition to the daily field care and inspection. It is quite common for users to specify shorter intervals.

Periodic retesting of electrical gloves should be performed at the proof test voltage using specialized equipment designed to gradually increase the voltage to the desired test level. The dielectric

test is two-fold: pass/fail on the ability to withstand the rated test voltage and, for electrical gloves, quantitative on the ability to prevent electric current from passing through the rubber goods above the maximum contained in the specifications.

Products passing the inspection and test procedures can then be returned to service. If you do not have the equipment required to perform these electrical tests, there are independent testing facilities that can perform the acceptance and inservice testing on behalf of end users. At a minimum, ASTM standards require that the inspection and testing process include the following steps: 1. Check-in 2. Removing previous testing marking 3. Washing using cleaning agents that will not degrade the insulating properties 4. Visual inspection of all surfaces (inside and out) 5. Electrical testing 6. Final inspection 7. Recordkeeping 8. Marking 9. Packing in appropriate containers (“appropriate containers” means boxes, or similar sturdy packaging materials to prevent folding, creasing or similar loose storage that can cause stress on the rubber) for storage or shipment When selecting a test lab for use, make sure that it is a NAIL-accredited test lab.

NAIL stands for National Association of Independent Laboratories for Protective Equipment Testing (www.nail4pet. org). It incorporates the only Laboratory Accreditation for the electrical equipment test labs program in North America.

NAIL4PET helps develop uniformity in testing, and works in close association with the American Society of Testing Materials (ASTM International).

Of increasing interest is the “test it as you use it” approach. While AC is the primary method of electrical testing, the ASTM Specifications for Electrical Protective Equipment for Workers do include both AC and DC test voltages and maximum use voltages for safety.

Therefore, it makes sense to DC test electrical gloves for use in wind renewable power generation where there is exposure to DC energized circuits and equipment.

Overall, the hazards and risks associated with working on or around wind turbines are similar to those found at most power generation facilities around the world. The remoteness and confined space environment exacerbate the need for electrical safety.

Fortunately, there are practices that you can implement to prevent injuries and citations. Testing is a critical and required - yet often overlooked component to maintaining arc flash and electrical safety and compliance.

With several workers required to wear electrical gloves and so many different

testing intervals to consider, it is easy to see how compliance can fall through the cracks. Consider partnering with an electrical test lab that can test your electrical gloves AND manage the change-out process for you. Keeping these services bundled together under one roof will minimize outof-service time and save money by delivering a start-to-finish solution that includes cleaning, visual inspection, electrical testing, markings according to your safety protocols, and shipment to your jobsite so that you can focus on other work priorities while staying safe, productive, and compliant!

Remote blade monitoring in extreme weather

by Alexander Steel

W

ind turbines that are used for power generation around the world come with operational challenges, as do all forms of power generation. Extreme weather and a changing climate can pose an exceptional threat to wind energy assets. Turbine blades are continually exposed to harsh winds, precipitation, and more, and must be periodically inspected to identify damages and erosion that can interfere with their operation. Unfortunately, these inspections are often conducted too infrequently to identify damages before they worsen to create more costly and hazardous concerns. Luckily, breakthroughs in remote monitoring technologies allow operators to actively identify and address these issues between inspections and upon onset.

Extreme weather impacts on wind turbine blades

Though wind turbine blades are designed to withstand weather conditions, they are still prone to damage. Lightning strikes, for example, can cause a variety of damages, with the most severe issues resulting in blade failure. Rain, hail, snow, and high winds can also degrade the blades, leading to erosion and decreased performance.

The following blade issues can result from extreme weather events: • Cracks Cracked wind turbine blades can be caused by a range of factors, including fatigue, manufacturing defects, lightning strikes, icing, and the effects of high winds. If left undetected, cracks may propagate and lead to complete blade failure.

• Ruptures and perforations Lightning strikes, variable wind conditions, and fatigue can result in blade perforations or ruptures such as split tips and trailing edges. These defects can allow the elements to affect the interior of the blade, especially during cold temperatures, leading to costly repairs and potential failures.

• Delamination Delamination may occur on or below the surface of the blade skin due to an impact, lightning, or a defect during the manufacturing process when the blade material fractures into layers. This can occur with object collisions, as well as lightning strikes.

• Bond line failure Over time, structural fatigue can result in adhesive, cohesive, and substrate failure for bond lines.

• Leading edge erosion Exposure to rain, hail, dust, ash, humidity, and moisture cause a gradual degradation of the blade's surface. This results in an inefficient aerodynamic profile and loss of production.

Acoustic Emission (AE) sensors

Figure 1 – Damaged blade: Remote monitoring technology can be used to detect blade damages caused by lightning strikes or other extreme weather events, earlier than traditional inspection methods.

Figure 2 – Laminate repair: Identifying damages early enables turbine operators to prioritize inspection, maintenance, and repair activities with more informed decision-making.

2022 MAY• JUNE /// www.nacleanenergy.com

Additional benefits of remote monitoring

• Blade condition data is available in real time to give operators and engineers greater insight into the overall fleet condition.

• Early damage identification allows timely scheduling of maintenance and repair visits before problems worsen.

• Data available through continuous monitoring allows each blade to be ranked and inspections or repairs to be prioritized.

Key takeaways

Traditional inspection method issues

Since wind turbines are constantly exposed to the elements and an increased number of severe weather events, frequent inspections are a critical part of ensuring their longevity and high-performance.

Unfortunately, traditional inspection methods — usually conducted by rope access technicians who perform various nondestructive testing (NDT) methods to find defects — are typically only conducted every six months to three years, allowing time for damages to form and propagate in between inspections. These methods also require turbines to be taken out of service, which lowers a site’s overall generating capacity. While drone-based inspections are efficient, they too have their difficulties.

As a result of these methods and the associated obstacles, many defects go undetected for a long period of time. This results in extensive, costly repairs. Early detection of defects can allow for improved performance, lower repair costs, and the reduction of blade failures.

While some aspects of wind turbine systems can be maintained without human interference, condition monitoring and fault diagnosis play a crucial role. Thanks to advances in monitoring technology, storm damage on blades can be detected before defect propagation occurs.

Acoustic Emission (AE) technology uses remote sensors to detect damages at their onset, and alert operators in real time to events, activity, and integrity condition degradation.

The data collected by these sensors can be used to track trends and improve the overall performance of wind turbines. By using data from remote sensors, operators can make more informed decisions about how to operate turbines safely and efficiently.

The use of AE technology has made it possible to track blade damage with increased accuracy, without needing to take the blade out of service. The integrity of each blade is monitored with one AE sensor installed in each of the blade bulkheads, while a data collection system is installed in the hub. When an instance of damage initially occurs on a blade, the sensor hears this change and sends out notifications via a web-based portal.

The information from these devices continuously flows into an application portal through either cellular or Wi-Fi networks. This provides site managers, fleet engineers, and operations teams with a live status on the turbine blades' condition, as well as historical records for any changes to its condition over time. Access technicians or remote drone operators can be immediately dispatched to further evaluate the damages and, if necessary, perform repairs.

Figure 3 – Real-time data: Identifying Through a web-based data portal, operators can access real-time blade integrity data during extreme weather events, so they’re aware of blade issues that require immediate remediation.

Remote monitoring technology What can be done to maintain the operational efficiency of wind turbines exposed to extreme weather conditions?

The digital age has brought about an effective answer. The solution is to supplement traditional inspection methods with remote monitoring technology.

Ultimately, the use of remote blade monitoring can help wind turbine operators protect their investment and help to ensure that their turbines are able to generate power reliably, even in the most extreme weather conditions. While remote monitoring isn’t intended to completely replace periodic inspections, it is a valuable tool that provides immediate weather-related damage alerts, notification of active versus stable defects, and prioritization of inspections and repairs.

This has the potential to substantially reduce repair and inspection costs while allowing for confidence in operation despite extreme weather conditions.

Fall Protection at Extreme Height

by Stephen Hartsell and Jill K. Alexander

By law, work at height requires safety measures to adequately protect the worker. It stands to reason, then, that work at extreme height requires extreme safety measures. OSHA mandates fall protection: in general industry for heights as low as 4 feet; in construction at just 6 feet; and, for scaffolding at 10 feet. With the average height of a land-based wind turbine at nearly 300 feet – about the height of the Statue of Liberty – those in the clean energy sector may wonder, what is different about fall protection at extreme heights?

It may surprise you that fall protection itself is the same whether the worker will be at 4 feet or 400 feet. The standard ABCDs of fall protection, or fall protection basics, still apply: A. Anchorage, the secure point of attachment for the fall arrest system, must be able to support the necessary load in a fall event with a suitable safety factor.

B. Body wear, most often a harness, safely distributes the fall forces over the worker’s body and provides an attachment point for a worker’s personal fall arrest system.

C. A Connector, such as a lanyard or self-retracting lifeline, securely fastens the worker’s body wear to the anchorage and arrests the fall to allowable forces.

D. Descent and rescue are an often overlooked yet critical component that ensures a fallen worker can be lowered (or raised) to safety in a prompt manner.

Risk assessment is the first step when working at any height.

This is where factors unique to both the specific jobsite and to extreme heights in general can bring additional challenges. While 20 percent of fatal falls are from heights of just 10 feet or less (more people are, in fact, working at lower heights), elevated work environments can be unforgiving. Awareness of the added risks at extreme heights is key.

• Rescue will be more challenging: When working at extreme heights, available resources may be scarce. Considering that it likely took additional time for the worker to get to the higher surface, the same will be true for the rescue team. It is critical to have a proven, practiced rescue plan.

• Wind velocities are more extreme: By design, a wind turbine is exposed to higher winds. This can cause loss of balance, impair visibility, and lead to stiff joints and fingers.

• Sun exposure is more extreme: By definition, solar panels will be located in high sun areas. Extreme heights are closer to the sun and often in open areas. This can cause hazards ranging from inconveniences such as sweating and glare to

serious concerns such as a heat stroke with loss of consciousness.

• Unique structures may have challenging obstacles: Wind turbine blades, heavy solar panels, and intersecting cables are just a few of the built-in hazards that workers need to navigate around, under or through.

• Energy involves electricity: While not intrinsic to extreme heights, the added hazard faced in any situation with an electric element is worth a mention since many utility services operate at excess heights.

©2022 Safewaze Equipment selection and inspection are crucial components in fall protection at height. Every tradesperson knows you need to have the right tool for the job and take proper care of those tools. Your personal protective equipment (PPE) is no different. o All PPE must allow for comfort with unrestricted movement and proper ergonomics for long term health. o Given the unique challenges of extreme height, lightweight materials are generally preferred; aluminum components can offer valuable weight reduction. o Materials must also be weather resistant and able to withstand the elements, which is particularly important for ropes. o Trailing rope grabs (those that follow the user smoothly) are generally preferred for better mobility and increased freedom of movement. o Pads that breathe can reduce distracting and potentially dangerous sweating, as well as helping to prevent heat exhaustion. o Always inspect every piece of equipment before each use. Conduct additional inspections as required by the jobsite partners and relevant laws. Use of an inspection checklist helps make the process more efficient and ensure that nothing is missed. Immediately remove any items that do not meet inspection criteria from service.

Following the critical ABCDs is the letter “E” for education. Train early and often.

Early training is especially important as 20 percent of fatal falls occur in a workers’ first two months on the job. Every worker should understand the nature of the job and the specific product usage for the required safety equipment. Workers and leaders alike must be empowered to recognize and question unsafe conditions within a culture that is committed to physical and mental safety. Leadership must understand relevant regulations and requirements that impact the jobsite.

Fall protection at every height is a balance where doing the right thing wins. It allows companies to work efficiently, meet deadlines and budgets, avoid violations and, most importantly, send every worker – whether at 400 feet, 4 feet or on the ground – home safely each night.

Bankable Wind Data for the Construction Industry

by Eduardo Estelles

W

ind sensors have a critical role in the wind energy industry: they collect data that is used to estimate electricity production, which then calculates revenue during the project lifetime. The same principle can be applied for safety purposes in the construction industry, especially in projects that involve tower cranes. Historic wind data can be analyzed to schedule lifts and other weather sensitive tasks more efficiently. At the same time, live measurements can be used for short-term decisions, complementing historic data.

The wind energy industry has driven innovation in sensor technology, but there is a technical challenge when using this technology in construction applications. Most sensors that are currently in the market focus on lower wind speeds such as 3-7 m/s, which are typical in meteorology applications and wind energy projects. On the other hand, tower cranes and high-rise constructions are often exposed to wind speeds of over 30 mph (>13.4 m/s).

Project developers in the wind power industry use measured data to estimate generation in terms of probability figures like P75 and P90.

• P75: Generation level that will be exceeded by the wind turbine 75 percent of the time.

• P90: Generation level that will be exceeded 90 percent of the time.

Development banks and other financial institutions are very interested in these figures when financing a wind farm, since it describes the project’s loan payment capacity. A similar principle can be applied in the construction industry: wind data is not associated with a revenue stream like in wind turbines, but it can help construction firms avoid major costs. If a crane rental company knows the times of the year when high winds are more likely at each site, this information can be provided to contractors for more effective scheduling.

What is the cost of wind in the construction industry?

According to a two-year study across 148 construction sites in the UK, a typical €200-million project can suffer the following impacts as a consequence of adverse weather: • An average direct cost of €250.000 (about $275,000 U.S.) per day. This includes labor, leased equipment, and penalties for missed deadlines.

• This figure does not account for indirect costs such as health & safety, contract disputes, loss of profit, loss of reputation, etc.

Crane operators and construction managers know they can proceed safely when wind speeds are below 30 mph (13.4 m/s), and that they must stop at speeds over 35 mph (15.6 m/s). In the 30 - 35 mph range, however, deciding between continuing or suspending construction activities leads to many disputes and disagreements.

In the study, wind speeds below 30 mph were measured 58 percent of the time, and wind speeds above 35 mph were measured 15 percent of the time. However, wind speeds within the uncertainty range of 30-35 mph were measured 27 percent of the time. For a typical construction project, this means project managers can expect many days where the decision to pause lifting is not clear.

In the wind power industry, it’s now possible to forecast how the wind will behave during the next 10-15 years, and analyze the financial performance of a project based

on this data. When the same concept is applied in the construction industry, contractors and crane rental companies can know what site conditions to expect during the next few years. The weather is unpredictable in terms of specific dates and hours, but predictable in terms of general patterns and profiles.

Using wind data effectively in tower crane operation

Having accurate wind data is important, but construction firms cannot ignore the role of human interpretation. Contractors need to ensure that crane operators, project managers and other staff members are provided with exactly the same data.

Otherwise, they may reach different conclusions based on measurements from different sources. An anemometer installed 10 m from the ground will give very different results than a cranemounted weather station at 130 m.

Crane operators and project managers must also be aware that the average wind speed does not tell the entire story: turbulence intensity is also critical.

A tower crane subject to constant 25 mph winds will not experience the same forces as another crane under changing winds with an average speed of 25 mph. Safer decisions are possible when average wind speed data is complemented with turbulence intensity.

Based on lessons learned from the wind power industry, the following general recommendations can be made for wind measurements in construction projects: • Use previous measurements as a reference for data correction.

• Use data from surrounding projects, ideally those with similar conditions: similar crane height, season of the year, etc.

• Keep a wind database for the last 5-10 years, to be used for regressive forecasting.

Crane rental companies can help their customers by providing centralized wind data, which can then be used for sitespecific forecasts. The value provided by this data for construction firms can be compared with probability figures like P75 and P90 in the wind energy industry. In other words, crane rental companies are not only renting their equipment with this

approach, but also their accumulated weather data and expertise.

• The combination of historic and live wind data can be used to justify delays caused by unfavorable weather, helping contractors avoid hefty fines for missed deadlines.

• Construction firms can also be provided with crane-specific wind forecasts, instead of relying on general forecasts that may not reflect the exact site conditions.

• Project managers can rely on this data to schedule critical activities like lifts and concrete pours more effectively.

With a centralized wind database, crane rental companies can estimate the potential number of winded off days for a project, based on its location and schedule. This information can be used to identify the best months for lifting, when the potential impact of high winds is the lowest.

Real life example: winded off days in February and March, 2019 and 2021

Weather monitoring services allow crane rental companies to access centralized data for their entire crane fleet. They can create a site profile with historic wind measurements from nearby tower cranes having at least one year of data. This data can be standardized for different crane heights and seasons, and combined with 5-10 years of historical measurements from wind databases.

The following chart shows the number of winded off days in 2019 and 2020, between the months of January and August: This chart shows an example of the typical differences that can be expected from year to year: 2019 had 3 winded off days in February and 9 in March, which was reversed in 2020, with 10 winded off days in February and 3 in March. A detailed analysis of the measured data revealed that winded off days tend to happen by late February and early March. Forecasting exact dates is not possible, but contractors know they can expect frequent high winds at this time of the year. If a critical lift is scheduled at this time, project delays are very likely.

As more construction companies use centralized wind data, the size of the database increases and more accurate forecasts are possible. Crane manufacturers and rental companies who keep an organized database of historic wind speeds can provide added value to their customers. However, this data must be highly detailed to be useful in future projects, complemented with information such as project location, measurement height, and time of the year. Of course, customer privacy is also an important consideration when using centralized weather data. Historic wind measurements should belong to the customer, and used anonymously when forecasting weather conditions for other projects.

These new leads can be used either in a manufacturing plant or in the field for maintenance. The KC-C test leads provide a complete and convenient solution for supplying reliable leads that are long enough for testing the continuity of lightning protection conductors in turbines. They offer accurate results and eliminate the time-consuming, inconvenient, and unreliable process of engineers and technicians having to fabricate their own test leads. Available in two lengths, 328ft and 164ft, each testing lead comes standard on a heavy-duty cable reel that is fitted with a friction brake to avoid tangles while reeling out the cable, and are rated to 10A. Each lead set includes two test leads fitted with a duplex handspike for probing the lightning receptors on the tips of the turbine blades. They are also fitted with a robust Kelvin clip that is designed to offer ease of use, while providing consistent and reliable connections that are needed to ensure accurate and repeatable results.

The KC-C test leads also feature hook terminations marked with C or P to ensure the right connections are made, and a cable guide on the cable reel to assist with orderly rewinding. These lightweight lead sets, weighing approximately 17lbs, use a duplex connect test lead system that allows probes or clips to be changed quickly and easily on-site. When combined with the DLRO2, they have a combined weight of less than 20lbs.

Work shoe ready to keep wearers cool and supported

Comfortable safety

Sulzer & Schmid Laboratories AG, launched its latest 3DX High Productivity (HP) solution specifically designed for high volume inspection campaigns. Thanks to advanced automation and AI-enabled analytics, 3DX HP delivers a streamlined single-stop process, making it an efficient rotor blade inspection solution. Fully autonomous drone technology makes it easy to use, from take-off to landing.

No manual intervention is required. Rugged and resistant, the UAVs are programmed to capture high quality imagery data in a systematic way covering the entire surface of the blade in a single-stop, 15 to 20-minute flight. Repeatable, with perfect image framing, it offers immediate image quality assurance in the field. The proprietary browser based 3DX Blade Platform integrates every aspect of the inspection in one place. In combination with the 3DX Blade Platform, the 3DX HP AI-enhanced analytics enable a turnaround time from image capture to report of just 5 days. High-quality images with highly accurate metadata indicate precise damage location and sizing, enabling a fully transparent view of the blade health status of the entire fleet. The repeatability of the process means that results can be tracked over time to monitor damage progression, to make informed maintenance decisions and provide lifetime documentation.

XL Specialized Trailers features the BladeMate Flip Extension, a solution for hauling longer wind turbine blades. The Extension provides significant cost savings to haulers over purchasing a new trailer. XL’s 27ft 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. The XL Blademate Flip Extension was made to be user friendly. By moving the lever at the front of the trailer, six-inch 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.

Cable triplexing solution

Electrical equipment and services

Elevator safety and training

Quality wind blade production

The VelociWrapper is an MV cable triplexing solution that is fast, cheap in materials, and provides a finished product with a tightly wrapped, triplexed bundle. Self-powered and self-operating, the machine requires no external power connections, has no motor, and is rotated by the twine being pulled through a patented pulley system. The VelociWrapper idea came when a couple of guys with a lot of wind farm and solar farm experience, as well as equipment design experience, came together to figure out a way to triplex and bundle cable.

Electrical Consultants Inc. (ECI) was incorporated in 1985. For over 35 years, their in-house portfolio of services, including overhead and underground transmission engineering, substation and switchyard design, industrial power systems design, land survey and construction staking, right-of-way services, environmental planning, project management, construction management, and procurement services have provided a key resource for hundreds of utilities.

ECI brings extensive experience in power delivery services through 500 kV to their clients.

Highly trained elevator mechanics from the International Union of Elevator Constructors not only keep elevators running, they keep them running efficiently, and above all else, safely. They have over 32,000 trained professionals within 600+ elevator companies that provide over 8000 on the job hours and 2500 classroom hours. Whether it’s installation, repair, maintenance, compliance, or safety inspection they are ready to serve elevator lifts needs. Their staff sits on the ASME A17.8 code committee that writes the codes for these elevators and they fund a safety program that helps to protect their workforce in the field.

Raptor Fasteners have been used in wind blade production for many years in the US, Canada, Europe, India, China, Brazil, and other countries. They hold core materials in blades, including balsa panels, in place during infusion process including VARTM and fiberglass layup. Raptor Fasteners can be left in the finished product, since it is a glass reinforced composite, and will not rust or cause delamination.

Raptor Fasteners can be cut, sanded, and shaped without damaging blades or abrasives, and are easily "wetted out" by composite resins and reinforce a good interfacial bond is made with the matrix. Raptor Fasteners save time and ensure quality for wind blade production.

When Solar Goes Polar How to get durable, reliable PV in extreme northern conditions

by Chase Anderson and Chris Lantz

U

tility-scale PV projects throughout the Northeast face the extremes: brutal cold, heavy snow loads, winds, rocky soils, and frozen ground that can result in devastating frost heave conditions. With most of the choice flat sites already built out, developers looking at steeply undulating terrain for more competitive leases do so at a cost: these sites often feature compacted soils, glacial till, and cobble over shallow bedrock pocked with boulders.

Construction challenges abound. Frozen ground slows installation, while spring thaws can create a muddy morass. Both serve to narrow the window of opportunity for getting things done. Developing solar assets under such challenging conditions can be daunting, but following a few best practices and working with partners experienced in managing the Northeast’s challenging conditions can make the difference between long-term returns and short-term failure.

Digging deep to set a solid foundation

Two key issues create the biggest below-ground headaches in the Northeast: Frost heave and pile refusals.

Frost heave — the upward ground movement that occurs as soil freezes — forces the soil apart and causes the ground’s surface to bulge. Frost heave can be particularly severe in the glacial till that is common throughout the Northeast.

For PV plants with driven piles, the foundation also can be subject to adfreeze, in which the frozen soil adheres to the piles’ surface. Adfreeze combined with frost heaving results in frost jacking, which literally lifts the foundation, resulting in margineroding repairs to maintain system integrity.

Refusals are another risk inherent to developing PV in the Northeast. Dense, rocky soils can conceal hidden boulders, causing unexpected and schedule-endangering delays when piles cannot be sunk.

To eliminate refusal and adfreeze risks - and control the possibility of frost heave ground screws are far more suitable to these conditions than driven piles.

Consult with partners familiar with the differences before committing to your foundation decision. Ground screws are quick to install and ideal for rugged sites, but require special equipment, more units than piles, and a higher upfront material cost.

Driven piles are affordable and reliable with lower upfront material and construction costs on typical sites, but are problematic on rugged terrain.

Assessing the situation above ground

Three primary factors influence design decisions above the ground: Snow, wind, and site topography.

Snow is the biggest factor. Racking must be designed to withstand and, if possible, shed heavy loads regularly. Building codes written for roofs often fail to account for solar projects. Snow that slides off a roof has several feet in which to pile up. But when

52

2022 MAY• JUNE /// www.nacleanenergy.com

it sheds from a ground-mounted solar module, it only has about a three-foot fall to the ground; after that piles up, there’s nowhere left for the snow to go.

Adding height between the module and the ground means crews must do more construction work at an awkward elevated level above their heads, sometimes requiring ladders.

Additionally, to bear the weight of more snow loaded on the modules, the purlins have to get bigger or the spans smaller. Look for a racking partner who conducts robust load-testing measures such as increasing loads with artificial snow during the winter, or loading test structures with as much as 13,000 pounds of bricks in warmer settings.

Wind is another concern in the Northeast, both on the coast where hurricane-force gales must be considered and along inland lakes. Make sure designers have done thorough wind tunnel testing to account for the varying angles of force possible on the project site. Some racking manufacturers use advanced software to simulate the most cost-effective design for your site’s unique wind profile.

Rugged terrain also poses an above-ground challenge. Steep slopes and undulations require flexible racking that can accommodate up to 36 percent slopes in all directions, aiding install-friendly tilt angles from 5 to 35 degrees.

During the initial design phase, make sure your partner optimizes the tracker system to be cost competitive mechanically, for constructability, and with regard to topography. Considerations for steep and undulating terrain are made to best balance these three design parameters: mechanical feasibility, constructability, and topographical terrain considerations.

Structural calculations shouldn’t just analyze the racking in a perfectly flat configuration, but also assess how on-site slopes affect span length and beam

configuration. These kinds of mechanical changes can affect the lateral loads of snow and wind on foundations, requiring further adjustments to maintain integrity.

Case study: Delivering quality in less-than-ideal conditions

Converting a former undulating hayfield in Sangerfield, New York, into a 6.5-MW solar farm posed a number of unique challenges.

At the start of the five-month installation, the ground was frozen and installers often had to contend with snow; Sangerfield sees nearly triple the average U.S. snowfall. By the time the last of the site’s 17,038 modules went up, the grass would quickly sprout to waisthigh if installers didn’t keep it mowed. In between those two extremes, installation teams had to contend with thick, sucking mud that threatened to mire their forklifts.

As a former farming site, the Sangerfield property also presented the challenge of working around uncharted tile — drainage pipes — and surprise flood zones at the bottom of its numerous steep slopes.

This complex site required a tracking solution fit for the extremes: flexible, durable mechanics, and intelligent controls. The developer selected a system designed specifically for steep slopes, environmentally sensitive land, frost susceptible soils, and one that would eliminate 100 percent of the refusal risk.

Ultimately, Sangerfield offered so many challenges that the racking partner responsible for building this single-axis tracker site used it as a training opportunity to contend with the unexpected. Too muddy? Establish teams to carry components in by hand so that forklifts wouldn’t become mired. Too steep? Develop a flexible design that can accommodate terrain challenges of steep slopes and undulation.

Because the topography was so steep, designers divided it into two sub-sites of 113 rows each. They then installed two weather stations to communicate with a single network controller for the project’s smart-tech controls and data cloud. A repeater keeps communications flowing even where line-of-sight is interrupted by the undulating hills. Software within the system maneuvers each discrete module to ensure it doesn’t shade any neighboring modules, while still maintaining optimum exposure to the sun.

they offer. Ideally, align with a company that owns the whole process with in-house steel manufacturing, ensuring top quality and supply chain control. Integrated racking, and an installation partner with smart project feasibility software, can support you through your project’s lifecycle from start to finish.

After Disaster Strikes

Utility PV plant recovery minimizes revenue loss due to extreme weather

by Jessica Super

Solar losses caused by natural catastrophes are reaching alarming proportions. Natural catastrophe losses in 2019 were 25 times higher than non-weather-related solar losses in 2019.

When the winds relent and the floodwaters recede, it’s crucial to follow the right steps — and quickly — to get power generation back to peak performance.

Recovery from weather damage is complex, often even more so than initial plant construction. Unlike new builds, restorations involve balancing current production needs against deconstruction and replacement demands. It also requires engineering expertise to find compatible solutions when the old equipment isn’t available or reliable to use today.

From damage assessment and salvage expertise to insurance claims management and rapid restoration, asset owners need experienced personnel to keep revenue loss under control. Ideally, a cohesive team manages the work through a single touchpoint to mitigate production losses and bring your PV asset back online to peak performance.

What follows is a step-by-step guide to a rapid recovery.

What works, what doesn’t, and what to do about it

First things first: Conduct a careful assessment of what’s gone wrong, and what’s still good.

Bear in mind that initial impressions can be misleading; even if damage appears to be minimal, there is value in documenting every aspect of the site that appears to have

THE RACK THAT’S READY WHEN MOTHER NATURE ATTACKS

been affected, even superficially. Take pictures, note components that may no longer be in production, and determine which OEMs will play significant roles moving forward.

For sites with more extensive damage, coordinate a grid-by-grid drone flyover to map the level of destruction, including standard and infrared views. Insurance companies often cover drone inspections because they want to know what they’re dealing with just as much as you do.

While time-consuming, scrupulous documentation from the start prevents surprises during restoration and can help stave off change orders down the line. Transparency minimizes revenue loss by ensuring that every stakeholder — the asset owner, operator, insurance provider, and all contractors — knows exactly where things stand at any moment.

Get production back online and keep moving

Minimizing the business interruption insurance claim can help to maximize recovery.

That means staggering on-site work to prioritize production recovery and curtail interruptions. For example, if one inverter is down simply because of a ground fault but the rest of the array is in good shape, prioritize restoration at that location to get an entire section of the plant back online.

Develop multiple contingency plans so that if one repair must be delayed, other activities can be slotted in immediately Pre-assembled components to keep the project moving forward. If make assembly a snap! components delivery is delayed in one area, shift work immediately to a process Adapts to work on a variety of that doesn’t require new parts. This helps roof types to keep personnel active at all times.

Salvage where possible, replace where needed

Before beginning restoration work, set standards for testing damaged equipment and establish criteria about what can be repaired and what should be replaced. Again, restoration expertise can prove invaluable at this stage.

While it’s important to be flexible and continue using viable parts, quality must take priority.

Salvage following a disaster often means weaving together still-functional older parts with state-of-the-art PV technology. Sometimes the damaged plant’s original equipment is no longer being made; with so many solar equipment manufacturers going out of business, restoration experts can help discern what may be obsolete and a solution — including manufacturing replacement parts if needed.

Bring insurance in early and often

The plant's insurance carrier is one key stakeholder often brought in too late in the process. To avoid this misstep, be sure to establish open communications with insurers from the start by familiarizing them with PV best practices as needed, and ensuring they have access to all documentation.

An insurer likely will have its own vendors tracking the project, such as subrogation and investigations teams. Different documentation may be required at each level of the claims process. Insurers often want to vet contractors and see rapid progress toward repairs — particularly if they’re paying lost production damages — but they also want to see extensive validation to justify bids.

This is where a full-scope general contractor can be invaluable. A consolidated umbrella company can be responsible for any subcontractors required to restore the damaged PV plant. Establishing that single point of contact early can be the difference between collecting a full insurance claim and incurring substantial losses due to unforeseen delays

Keep components coming

Particularly with current supply chain issues, you’ll need experts with a deep supply network, extensive Tier 1 procurement agreements, and, ideally, an extensive inventory of spare parts on hand at regional warehouses.

That’s why it’s helpful to choose an expert team with substantial EPC experience in addition to restoration and remediation. Construction experts know where to source elusive components to prevent work grinding to a halt during an extended wait for parts.

Lessons learned: A case study in wind damage recovery

After gusts up to 80 miles per hour ripped through a PV power plant — damaging 15 percent of the site’s trackers — it was discovered that more than one-quarter of the trackers weren’t operational before the winds hit, making it impossible to maneuver them into a protective stow position. As a result, 233 of the 1,600 trackers were damaged and had to be restored.

Initially, the plant owner relied on O&M personnel to assess the damage and submit insurance claims. Four months later, though, restoration work had yet to begin.

Within four weeks of contracting with restoration experts, they had a plan in place to deconstruct the damaged areas, conduct testing to determine what could be salvaged, and source replacement components.

Ultimately, still-useful original technology was blended with modern replacement equipment to repower the site without any costly redesign. And while the asset owner had anticipated replacing damaged components for roughly $1.75 million, they were able to salvage 70 percent more modules than originally forecast, saving $1.3 million.

Additional savings came from reducing business interruption damages, shaving 126 days off alternate restoration timelines, and project results coming in 40 percent lower than alternative bids. Total savings: $3.3 million.

Choose an all-in-one partner for maximum results

Restoring a weather-beaten PV plant means far more than picking up the pieces and cobbling them back together again. Complex site recovery demands experts with dynamic EPC capabilities who can mobilize quickly with in-house repowering, engineering, and construction specialists.

It’s also helpful to choose a team that can go beyond rebuilding to full-site optimization, bringing plans back to peak production performance. Partnering with a team that also offers O&M expertise means the strongest possible post-recovery performance.

Trenchless Solar Cable Management

Above ground cabling alternative delivers above average results

by Michael Markowitz

T

he ultimate goal of every solar plant is to harvest as much clean energy as possible while consuming the fewest resources. Profitability depends on squeezing the most wattage out of every dollar spent on materials, labor, and repairs.

Advances in photovoltaic cell efficiency, combined with falling costs and a push from the federal government, has made solar power more popular than ever. So popular, in fact, that we are running out of space; many of the prime locations for high mega-watt solar farms are either already developed, too expensive, or not in proximity to major population centers.

The result is that more utility-grade solar plants are being constructed on lessdesirable lands or locations previously used for other purposes, such as agricultural farms, commercial nurseries, even capped Superfund sites and decommissioned fossil fuel plants. Often contaminated with pollutants, these properties are no longer suitable for commercial development. But they can be repurposed as clean energy producing assets. The question is: How? Let’s put aside the environmental issues for a moment to consider the enormity of the task. Even on pristine land, developers will encounter obstacles when trenching - they must account for the effects of derate on buried or bundled cables. Derate is defined as the percentage of electrical capacity that must be reduced to offset the friction heat buildup generated by bundling or burying cables. Article 301 of the National Electrical Code states the derate factor can be as high as 50 percent when running 10 or more buried cables in parallel. That means laying 500 Kc mil cables to realize 250 Kc mil ampacity throughput. Think about the cost of all that wasted copper!

Solar plant cabling options

Utility-grade solar plants are large-scale engineering marvels, occupying hundreds to thousands of acres, with hundreds of rows of solar panels tightly packed into avenues for maximum energy capture. Beneath these arrays are equally intricate pathways of high ampacity cables transporting direct current to inverters at the end of each row, as well as low voltage data and AC lines for sensors monitoring weather conditions, panel performance, and to power the motors allowing the panels to follow the path of the sun.

56

2022 MAY• JUNE /// www.nacleanenergy.com

Solar plant developers have several options when cabling the arrays.

• Bury cable. The traditional method of laying cable directly in the ground is labor intensive, dangerous, sloppy, and expensive. There may be delays caused by weather and geological obstacles. Derate is considerable as earth traps heat, and cable repair is hindered by lack of visibility to an exact failure point.

• Run cable inside a pipe. The cable is still trenched and buried, but protected from moisture and the weight of earth. Derate is actually increased due to heat entrapment by the pipes, but repairs are easier as cables can be pulled and replaced without digging.

• Bundle cables above ground. Now we're getting somewhere; running cables above ground is faster, less expensive to install, avoids trenching/terrain issues, and provides a high level of accessibility for repairs. Above ground bundling will experience some derate due to the cables touching, but less than when inside a pipe. Best for low ampacity DC and low voltage AC cables.

• Above ground (Free Air) installation. The nirvana of power transmission physics, Free Air involves no bundling; cables are run above ground with separators that allow heat to dissipate into the air. The derate factor is greatly reduced or eliminated, which lowers cable impedance 25–40 percent over an entire project for a better ROI. Along with its relatively low material cost and minimal labor requirements compared to trenching, Free Air becomes a very economical solution for high ampacity DC cables.

A case for free air installation

Now let’s return to the environmental and less-than-desirable-location issues, and see how Free Air installation can solve these problems and alleviate trenching and derate factors.

A massive, 630-megawatt solar plant was recently constructed on what was an agricultural farm in the southwest. You’d think there would be a lot of advantages to building a solar plant on farmland: the land is flat, the soil already tilled and free of boulders, roots, and other obstacles.

However, the developer feared trenching would expose workers to high concentrations of fertilizers and pesticides accumulated in the soil from decades of growing crops.

There were concerns that rain-induced runoff containing hazardous compounds (brought to the surface by digging) could enter the local water supply. Project engineers decided it was best to leave the ground as undisturbed as possible. The solution: Free Air installation.

Above ground cable conveyance employs tensioned messenger wire to transport multiple layers of DC cables from the solar panels to an end point under each row. The wires attach to the same I-beam footings driven into the ground to support the solar panels.

Brackets are attached with cable spacing trays seated at measured intervals.

Complying with NEC Article 301, the trays maintain a uniform 360° space between

additional $3.82/hour, or $45.84/day per run (assuming a 12-hour day). If the average utilitygrade solar plant has 125 runs, that equates to $5,730 of daily incremental revenue, or over $2 million dollars per year—every year!

Designed to install quickly, reduce labor and material costs, and harvest more energy daily from the same assets, Free Air systems revolutionize solar plant cable conveyance and deliver above average results.

each cable that allows heat to dissipate into the air, thus maintaining full ampacity and eliminating the need to derate cables.

Using this method, cabling was finished ahead of schedule and under budget, with installers running about 1,000 feet of cable per day to achieve significant labor savings. Material cost savings were realized through lower ampacity cables that will be used to full capacity, and environmental concerns were eased as the ground was not trenched. Most importantly, the solar plant will realize a faster ROI by harvesting 100 percent of the power it generates.

Quantitative performance savings

Not only does Free Air cable conveyance save money on materials and labor, but it increases daily energy harvest by up to 8 percent over traditional methods. Here are the numbers to prove it: Post-construction, above ground cable conveyance systems have been shown to harvest thousands more watts of clean energy every day that otherwise would be lost to the effects of derate. Using the laws of physics and precise coefficient values for the resistivity of copper at different temperatures, it’s possible to determine the amount of power lost to Ohmic heating.

Algorithms convert anticipated power loss percentages into a dollars-and-cents estimate of incremental revenues that could be realized with Free Air installation.

This example illustrates the savings of a bundle of 36 cables, each 1,000 feet long and rated for 700 Amps, at an average ambient temperature of 77°F. When buried, the cables yield 8,072 watts per hour. Using above ground cable conveyance, the same solar array generates 8,779 watts per hour, harvesting an additional 707 watts per hour by not suffering from derate. Using an average Kilowatt price per hour of $0.15, each bundle of 36 cables can generate an

igh-density, low-profile, aerodynamic racking solutions are becoming a popular solution for sites with extreme winds, particularly in land-constrained Caribbean.

A case can easily be made for utilizing high-density, low profile ground mount racking solutions the Caribbean. This is based on the following parameters: • High Wind Design of up to 180 mph (based on ASCE 7 – 10) with the most cost-effective foundations • Long-term Insurability with high-wind design for hurricanes • High-Density Efficient Land Usage • Suitability for large variety of Soil Types • 78 percent Reduction in Raw Material Usage • Compact Shipping simplifies import process • Simplicity of Install means local labor force can be utilized • Reduced EPC Costs leads to reduced LCOE versus trackers and Fixed Tilt Systems High wind design – The racking solution has undergone extensive wind tunnel tests. It’s extremely aerodynamic, coming up to about waist level, which allows for it to achieve 180 mph winds with standard clamping solution (ASCE 7 – 10). Since it’s in an East West 8-degree tilt and low above-ground, there is minimal uplift to withstand much higher winds. There is already a project on the ground installed in the cyclone region of West Australia. There is an additional upcoming 8 MW project in the Caribbean with construction scheduled for this year.

High-density, land use efficiency – The solution can produce about 225 percent more MWh/acre than fixed tilt and tracker systems (according to DNV GL’s bankability report). As an example, a site in the central Caribbean (Dominican Republic) has a yield of ~1,532 kWh/kWp/year, which leads to 1,194 MWh/acre/year due to the efficient land use of ~0.78 MW DC/acre. For an island like Barbados, the solution is ~19 percent better with 1,819 kWh/kWp/year, 1,419 MWh/acre/year.

Location and sandy soils – The solution becomes even more attractive the closer it is to the equator, making the Caribbean an ideal location. Additionally, the solution has a wellsuited helical screw (anchor rod) that can be used in soft, sandy soils and only requires ~ 0.5-0.6 meter (1.64 – 1.96 ft.) foundation depth. A shallow foundation can prove useful to avoid hitting volcanic rock and removing the need for expensive pre-drilling.

Minimal materials – When compared to a conventional fixed tilt or tracker system, the solution uses 78-95 percent less steel. Conventional systems require I-Beam foundations of 10-15+ meters. Assuming 540-watt modules, 32x12 module block, 0.5 meter embedment, and 150 mm anchor rods, you’re are looking at 8,600 kg of materials per MW DC. Note, if the site is slopped or has some uneven terrain, the system may require additional material. Rods are inserted directly into the ground, removing the need for any concrete or other materials. The DC system, including the cables, is above ground so there’s no DC trenching.

Compact shipping – 40 ft. containers can handle up to 20-25T (country specific), meaning ~2.6 MW DC of racking can be carried in each container. This makes shipping to islands extremely efficient, which can be particularly attractive to islands with limited port sizes. This helps address current port congestion and shipping costs.

Simplicity of install – All tools required for the system are hand held. Since there is no heavy machinery, sourcing equipment is simplified. All tools are commercially produced, easily available, and simple to use. The simple design also allows for installation by unskilled labor. With 540-watt modules, a total of ~500 man-hours per MW is required for the DC installation, which is ~50 percent less vs trackers. Around 420

58

of those hours are related to DC installation; ~70 is related to waste handling, inverters, and site restoration. Approximately 60 percent of those 500 hours is done by unskilled labor, helping to simplify sourcing a workforce on a remote island. This particular aspect made the solution attractive for remote mining sites in Australia.

Bankability – The solution has been deployed globally on over 400 MW, making it one of the most used high-density ground mount solutions. Extensive Bankability report from DNV GL, wind tunnel tests by the IFI engineering firm, and over 2.8 GW of substructure supplied by racking company globally are all contributing to the bankability of the solution.

EPC costs – Overall, there is a ~30-40 percent reduction in EPC costs (excluding interconnect). EPC quotes can be provided on a project specific basis upon request.

In summary, the solution is extremely well adapted and designed for the Caribbean’s extreme high wind environment. The solution’s high-density, reduction in materials, and simplicity streamlines the whole installation process by drastically reducing construction effort, logistics, and labor sourcing.

He brings nearly a decade of experience in the solar industry as a leader in the advocacy for solar and energy storage. He is raising awareness of how high-density solar solutions can play an integral role in the world’s transition to clean energy by solving issues of land availability, labor force sourcing, shallow foundations, extreme wind suitability, and ease of access to inexpensive solar globally.

Designing Solar for High Winds on Challenging Terrain

by Yezin Taha

As extreme weather impacts from climate change become increasingly widespread, solar developments are faced with entering more dangerous territory. Further, with available flat land areas becoming increasingly scarce, the industry must now consider project sites with histories of extreme weather events and challenging terrain. With challenging weather and/or terrain becoming the norm for projects, it is imperative that asset owners and EPCs do the appropriate project and product due diligence to select equipment that is capable of thriving in these environments.

To align the torque tube straight along the length of the row, the industry traditionally had two ways of approaching challenging terrain: grade the site flat, or implement variable foundation reveal heights. Neither of these options is ideal; they can lead to increased costs, complicated construction, and disturbed land. However, there is a third option of using solar trackers that follow the natural terrain, whatever it may be. This type of tracker eliminates the disadvantages from the other approaches, but requires more diligence in the upfront design. To begin the design process, EPCs and/or developers should generate 3D point files of the foundation locations. From there, racking equipment providers can identify the appropriate technology needed to accommodate the various angle changes early in the design process. This contrasts from typical project timelines, where the completion of a 2D layout during preliminary design activities is sufficient to get an accurate bill of materials.

Additional design work on non-flat terrain involves assessing how foundation wind loads are affected by the variable terrain, and accurately locating those foundations along the length of each row. Wind loads are affected by variable terrain; calculations based on wind tunnel studies should be available from the tracker supplier to understand those loads. Foundation northing distances decrease with increasing slope, which can be accounted for in 3D Civil CAD programs.

When taking these challenging terrain projects to regions with patterns of extreme weather, such as Kansas, New Hampshire, and Louisiana, dynamic stability and stow strategy are key considerations.

2022 MAY• JUNE /// www.nacleanenergy.com

In a perfect world, tracker providers will take all of the necessary preventive steps in the design process to avoid structural damage during extreme wind events, all while preserving the natural land by following the site terrain. However, since we can never completely eliminate all risks, it is crucial to have a tracker partner that understands how to deal with both variable terrain and high wind conditions. Plus, it is necessary for the EPC and the tracker provider to work together to design for real life expectations in our changing climate, and not just the lowest cost design.

Yezin Taha is CEO and Founder at Nevados, which works to help solar developers increase location site options, eliminate major costs of construction, and maximize power generation.

Nevados /// nevados.co

Equipment providers utilize stow strategies as a mitigation tactic for dynamic instability. During high wind events, trackers will rotate to a wind stow position; either flat or at a predetermined angle. Stowing at steep angles towards the wind provides greater protection from dynamics. These steep angles result in higher static loads, but reduce vulnerability to dynamic wind events at shallow angles. Fastrotating trackers that reduce the time to reach stow are favorable to reach the desired tilt angle as quickly as possible, and should be able to reach stow in less than three minutes. External dampers are a typical approach used to attenuate dynamic wind effects on the tracker rows, but can be a high failure component. However, tunable designs with variable damping, multiple damping locations, hard nodes in the structure to reduce natural harmonics wavelengths, and multiple dynamics disruption designs can eliminate the need for external dampers.

This combination of extreme winds and challenging terrain is to be expected in hurricane regions. The industry saw this first hand when Hurricane Ida hit the state of Louisiana in Fall of 2021. A number of solar developments in the area took direct hits, undergoing winds of 85+ mph for many consecutive hours. The majority of tracker systems sustained significant structural damage, with wind dynamics being the likely culprit. One tracker system survived the hurricane with no significant damage to speak of; that tracker system included the various wind dynamics mitigation strategies listed above.

PV Installers Keep Pace

by Robert Benedict

T

he complexities of being a solar installer today require many skills.

A residential installer with staying power has their operations, sales, service, and supply systems refined and reviewed via quality control measures. They also need the ability to secure all three financial options: cash, bank loan, and leasing.

Many US installers come from construction backgrounds. While there’s a bit of a learning curve involved in converting that experience into becoming solar systems installers, one of the more sophisticated areas of a residential installer is the sales system.

In 2005, installers did not have the tools for selling in the residential market; they were just beginning to develop market-specific sales tools. The biggest hurdle at the time was simply educating homeowners about the value of solar. This forced installers to learn how to become both sellers and teachers. No easy task, as it was not broadly known or understood how solar worked and the value proposition.

From then to now, the sales process has refined to almost an art. New technology allows the homeowner to see their house with solar on it before a single panel is installed. It’s also easier to demonstrate a clear return on investment on any form of payment method. The per Kilowatt-hour (Kwh) pricing utilities charge directly reflects how fast you reach breakeven.

For example, paying cash in an area where electricity rates are low means the return on investment will take longer. With a lease, the homeowner will get returns on their first bill after the system goes live. Based on present-day average degradation rates, with 40 to 50 years of returns possible, it is currently better to own than lease when considering ROI. The methods for obtaining prospects have changed dramatically, too. In the early years (2005 and before), solar was rarely featured in periodicals, newspaper and TV ads, with maybe a monthly discussion on a local radio station. Up until 2010, small pockets of the public were learning about solar and its value. Today, companies are using the full force of branding and marketing through the web, SEO, texting, ad stocking, and social media. Solar is part of our everyday life, with the expectation that most everyone will have solar on their homes in the near future.

Competition is intense, and each company has to find a way to win the sale.

Homeowners usually have three or four bids either in person or virtually.

The construction side of the installation process can be fraught with many difficulties.

It’s a matter of juggling safety, installation processes, scheduling, homeowner property awareness, equipment and supplies organization, and good management. When you spread this over 20 teams or more, potential complications are a big concern.

The stories are endless when it comes to accidents from an installation. Perhaps one of the most unfortunate is when the installer penetrates the roof of the homeowner. Sadly, there are cases where almost every penetration point creates a leak – and it’s entirely

preventable. Worse is when an installer falls from the ladder or house after forgetting or failing to buckle the safety harness, or refusing to wear one altogether because it saved time when there were only minutes left to install completion.

Newer products are available to help prevent ladders from falling, while allowing workers to walk on tiles without breaking them by distributing the weight evenly across multiple tiles or other roof surfaces. As the industry matures, installers learn new methods to get processes done, as well as faster and more efficient ways to complete installs.

Repetition is the best method for fixing the racking system. The installer has to consider a number of variables: How to move the modules from the ground to the roof and then place and secure them; how to lay the cabling and connecting modules to the inverter; which design will get the best performance from the installation? The key is to plan, know the plan, and follow the plan.

A 12 kW system can be completed in 4 to 6 hours if planned and managed well.

If the project is not well managed and planned, however, it can take twice as long.

All components, cabling, or tools should be at the job site when you arrive to install. If

you need something for the system and it’s not available during setup, you will lose the profit expected from the installation.

An independent survey of installers answered the following questions: 1. Which was most important – wattage, where manufactured, availability, and size of the frame?

Of the responses, wattage and availability garnered slightly more than one-third each. The remaining partial third was shared between the location of manufacture and the size of the frame.

2. What do you think about US solar manufactured modules? Answers were split evenly three ways between: “depends on price”, “highly interested”, and “not important”.

3. Do you purchase a premium brand? 83 percent of the respondents said “yes”.

4. When choosing a module, what factors do you consider? A third or respondents cited wattage, a third chose where modules were manufactured/availability, etc., and the remaining third was concerned with the size of the frame.

Overall, industry pros are bullish on the future of solar, especially regarding the residential market. Rapid changes in the PV industry has spurred dramatic changes in the requirements of installers. The market has been evolving at such an accelerated rate, given the speed of technology and the increasing number of companies gobbling competitors to gain market share, that successful installers must be flexible, agile, and even attempt to predict the future to stay ahead of the game.

Specialty spacer tool

The Mod Spacer sets the inter-row spacing between solar modules. With its twist-release feature, the Mod Spacer will not get stuck between modules, and the finger loop makes it easy to grasp. Due to its bright red color, installers will never forget their spacer on the roof again. The Mod Spacer is made of durable plastic, preventing it from scratching the panel or becoming a hazard when accidentally dropped off the roof.

Overcoming Terrain Challenges and the Ecological Effects in the U.S.

A

s the third-largest country globally, the United States' terrain varies from one coastline to the next. Of the 1.9 billion acres of land in the continental United States, only 18 percent is considered plains or flat land, where ground mount arrays perform at peak efficiency. Even with a fifth of the U.S. being the most optimal land for ground-mounted arrays, most of this land is unusable farmland or unprotected forests. This leaves more undulating or mountainous terrain for solar developers to acquire for projects. When developing a solar project, racking providers must consider the ecological effects, landscape, and subsurface. To overcome site challenges, racking providers also have to consider terrain challenges and acquire accurate site surveys. With this information, ground-mount arrays can easily be installed to achieve optimal performance.

A project destined for success contains the following: • A racking solution with multiple foundation options that can adjust to subsurface conditions.

• Posts that accommodate a greater degree of topographical changes, while preventing excessive shadowing on neighboring panels.

• Purlins that have the flexibility to support various modules, snow loads, and terrain.

While compensating for unlevel ground, these characteristics of a racking system make solar projects on unpredictable terrain possible.

The desired result of any ground mount site is a quality appearance that also optimizes energy output without unnecessary costs or environmental effects. One of the factors associated with many ground-mounted systems is site grading.

Unfortunately, site grading can unintentionally remove native plant and animal species through ground disturbance or erosion, as well as raise the project's costs with extra steps and equipment. Extensive grading for a construction site can be detrimental to the surrounding environment; potential ecological impacts should be considered during site planning.

One of the ways that many developers keep an environmental ethicality is by procuring a system that follows the contour of the site with no extensive grading.

Determining whether grading or any other groundwork is necessary can be resolved early in project development by acquiring accurate site surveys. A reliable site survey must be completed to obtain accurate data about land characteristics and assure an efficient project timeline. In addition, the topographical data gathered from the project location gives the developers and engineers the necessary information to secure the most efficient racking system possible. With today's technology and environmental concerns, racking systems are designed to fit the site, not the other way around.

Many racking providers must consider one price factor: steel costs, especially since the coronavirus pandemic.

Despite the rising costs of steel, many developers say that paying extra for more post length is still a better option than paying for site grading, especially given the potential ecological impact.

While compensating for unlevel ground, these characteristics of a racking system make solar projects on unpredictable terrain possible.

Save time, money, and lower project risk

Nextracker’s NX Horizon-XTR, is a terrain-following, single-axis tracker designed to expand the addressable market of solar power on sites with sloped, uneven, and challenging terrain.

NX Horizon-XTR’s terrain-following capabilities can reduce grading, minimize steel costs, and decrease project risks. NX Horizon-XTR breaks the paradigm of the “straight-line row” design constraint by conforming to the existing ups and downs of north-south ground slope undulations, so trackers no longer require installation along a single plane but can follow natural site contours.

Nextracker /// www.nextracker.com

Whether through materials or services, the ethics of how suppliers advise their customers is a much-debated topic in the solar industry. The goal of achieving the greatest profits seem to supersede all other factors that the racking design can directly impact. Choosing a racking provider that can tackle challenging terrain without causing significant harm to the natural environment is the best choice for solar developers.

Solar Customers’ Top Weather Complaints and How to Address Them

by Jordan Grimmer

Nearly half of all solar customer reviews that specifically mention weather-related incidents are negative (e.g., three stars or fewer). Among these negative reviews, the most frequently mentioned weather issues include the following: • Installation errors that contribute to roof leaks during rainy weather • Damage to the roof, gutters, and other property from snow-laden solar panels

Leaky roofs

Roof leaks that occur after a solar panel system has recently been installed on a home are typically just the beginning of many problems for homeowners — they also have trouble getting support from the installing company: “Currently have a leak in my roof where the solar is located. Reached out to have someone come out to do an inspection to see if the solar caused the leak or not.

They pushed my inspection out a full month. What used to be a bubble in my ceiling is now a large crack allowing water to pour into my house when it rains.”

“The solar system I purchased a year ago is generating solar energy, however the roof tiles that were broken by the labor crew caused a major water leak in my ceiling. And, [the company] refused to take responsibility.”

“Poor solar panel installation caused a leak in my roof. It has been 5 months of continuously trying to get the company to remove the panels so that repairs could be made. The leak is so bad that it has gone into the first floor and water is pooling in my light fixture.”

66

2022 MAY• JUNE /// www.nacleanenergy.com

A snow-safe solar build

Preparing for a rainy day

Post-install roof leaks can be attributed to either of the following: • Incompatible or old roofing - Not all roof types are compatible with a roof-mounted solar system.

Shingles and tiles made from hard materials like wood, clay, or slate are not ideal. Additionally, roofs that are 30 years or older are especially prone to leaks when a solar panel system is installed. Many customers may need to have their roofs replaced prior to going solar.

• Subpar installation - A large portion of roof leak complaints are from customers who had their systems installed by subcontractors with limited experience. While this may seem like a money-saving option for companies, it could damage their reputation when problems like these arise.

For many homeowners, snow is inevitable; in most cases, it will pose no threat to system performance or the property. If you install systems in snow country, keep the following in mind: • Recommend snow guards for high-risk roofs: Usually, low-pitched roofs of composite shingles are considered low-risk for “avalanche-style” events; however, roofs of varying pitches and materials could benefit from snow guards. If you recommend snow guards, be sure to do so during the initial consultation rather than after an incident.

• Don’t leave shoveling to amateurs: Homeowners often don’t know that any system damage caused by their own efforts to clean snow from the panels is not covered under warranty. Remind customers that, most of the time, snow will melt off the panels on its own. For cases where performance is severely affected by the pileup, clearly outline your company policy around panel cleaning.

A word about customer support

Rake through any number of solar customer reviews, especially reviews regarding the extreme weather, and you’ll find a throughline: positive weatherrelated reviews typically come from homeowners who’ve had a positive customer support experience. Rain and snow are unavoidable, but being available and responsive to customers is just as important as preventing water and snow damage in the first place.

“The installation was very well done. However, they recommended a pole to take off the heavy snow and it hasn't worked... The panels cause snow to build up on the roof and it is extremely difficult and dangerous to shovel off.”

“Problems started with the first snowstorm of the season which was 3 inches…. the snow/ice started to slide off the roof and bent my gutters. The second snow storm of the season was 10 inches. As the snow/ ice started to melt, it slid down my roof, ripping the gutters off my house.”

Can Solar Labels Last in Any Climate?

by Todd Fries

L

abeling for extreme environments presents obvious challenges, but even more so when it comes to labeling a solar installation.

To complicate matters, the definition of “durability” is nebulous. So much so that according to the National Electrical Code, a durable label is one that is “of sufficient durability to withstand the environment involved.” (Article 110.21(B)(3).

Figure 1 What does that mean? The manufacturer of the raw material may give a baseline life expectancy of two to five years, but as we all know, the labels must last much longer on a commissioned system.

The problem manufacturers face is that a label applied to a breaker box on the sunny side of the building is going to age differently than a label sitting in shade.

The typical disclaimer for an outdoor-rated label includes just about everything under the sun (pardon the pun).

Label deterioration can be affected by temperature and humidity, the angle of application, and even the level of air pollutants. The final sentence of most disclaimers is the same: “The manufacturer makes no claim of warranty regarding outdoor durability in actual end-user conditions.”

How’s a person supposed to spec solar labels for extreme outdoor conditions?

material type may be rated for outdoor use, the combination of materials can make or break an outdoor label.

First, consider the adhesive being used on the label. Is it acrylic based and UV stable? If so, does the application require adhesion to a baked enamel surface, like a standard breaker box, a powder-coated painted surface as found on some inverters, or wrapped onto Electrical Metallic Tubing (EMT) conduit? There is nothing worse than applying labels (every 10 feet according to NEC code requirements) to the EMT conduit and coming back 24 hours later to see them lifting and even falling off the raceway.

The face stock must also have UV inhibitors within the material. UV inhibitors will block a large percentage of UV radiation much as sunblock will keep us from getting a sunburn. This same face stock also acts as a barrier to protect the adhesive underneath.

Any of the printed graphics should use weather-resistant pigments that will resist fading. If the label is totally pre-printed, a good UV laminate will further protect printed text and images.

Figure 2

The most important thing is independent testing. Find a reputable label company that is invested in the solar industry. In most cases, they will have What to look for both historical and accelerated age testing. Accelerated age testing requires While there are many label and adhesive raw material suppliers, in most cases, the use of a Xenon Arc chamber, which incorporates intense light and they haven’t tested their materials on solar installations. In addition, once the mimics wet and dry conditions over a period of time. Because of the extreme labels are converted into their final form, the consumer has no idea what types intensity of the bulbs, the labels age at a rapid pace, allowing a company to of inks or laminates were used to manufacture the final piece. While a single project the rate of degradation over five, 10, 15 or even 20 years.

This, combined with actual outdoor testing, can provide reasonable evidence of durability. While there is still no guarantee ZTZ – THE PIONEER IN TRANSFORMER CONDITION MONITORING of a 20-year lifespan, the consumer can feel 40 YEARS EXPERIENCE ● 5000 SYSTEMS IN-SERVICE ● LIFETIME WARRANTY confident that the applied labels will endure the elements.

printed calculations is to use a good thermal transfer printer with UV-stable inks.

Such printing systems give you the ability to create almost any style or type of label that is required. In addition, these printed labels will be durable and fade resistant.

As for Xenon Arc testing, the photos of the label in Figure 1 show a before and after 16,206 hours of Xenon Arc exposure.

Depending on the type of test, 16,206 hours could represent about 25 Florida sun years of light. The laminate started to peel and there is only slight fading. This would pass inspection.

In some instances, a control sample is used by monitoring the label in actual outdoor conditions for many years.

In Figure 2, this solar-rated label and thermal printing have been exposed to actual outdoor conditions for 10 years. As you can see, even without an additional UV stable laminate, the variable black printing is still visible and functional. This label would pass inspection.

Some installers will take a shortcut.

Ever seen this? Handwriting with a “Sharpie” isn’t recommended. It may have the word “permanent” printed on the side of the pen, but Sharpies are not made with UV exposure in mind. In Figure 3, the image on the left is a label marked with a Sharpie; on the right is the same label after 1,400 hours of Xenon Arc accelerated aging. In the real world, and exposed to sunlight, the handwriting on this label could be totally erased in as few as one or two years. Even with a clear UV laminate, the ink will still fade.

Selecting durable labels is not easy, but if you concentrate on selecting reputable companies that can provide test results – and even limited warranties are a plus – the savings will mount up over time. It’s all about doing a little due diligence in return for label that can stand up to whatever the environment throws at it.

Duct sealing system

With a new, simpler design, the HomeSeal Connect 4.0 (HSC 4.0) duct sealing system from Aeroseal is easy to use and includes several updates improving its ability to apply certified, industry-standard methods to virtually eliminate duct leakage in any HVAC system. Enhancements include a stainless-steel solenoid diaphragm and new relay board contribute to more uptime and promote device longevity. Quad digital power control ensures tighter seals and prevents overheating. A field replaceable antenna extension allows technicians to repair this connectivity issue in the field.

The HSC 4.0 system injects a fog of nontoxic sealant particles into pressurized ductwork to safely seal air leaks as big as 5/8” and as small as a human hair from the inside. The water-based sealant particles only accumulate where leaks are located, gradually closing them. This ensures even leaks in inaccessible ductwork are sealed without having to open walls. HSC 4.0’s system software measures and records air flow and leakage in real-time. And once the ductwork reaches its target goal, a post seal test confirms the amount of leak reduction, issuing a certificate of completion showing before and after stats that equate to as much as a 90% reduction in duct leakage or more.

Serving North America For 20 Years Si-RS485TC-2T-v-MB Modbus Weather Station

Drawing from many years of custom design lift equipment, the Solar Trax is the result of a several year effort, starting with Bailey Cranes’ glass lifting Brandon Trax machine. The Solar Trax 824 lifts panels 8ft high and traverse 24ft to handle most solar field designs. The base machine is track driven, providing a high degree of traction and terrain-ability. Designed for rough terrains and increased slopes, the upper assembly automatically levels itself for increased stability and ease of panel placement. All hydraulic functions include Programmed Motion which combines multiple steps, such as “Raise-Left,” which raises the panels from the center position, trolleys sideways to the support frame, and lowers it in place. Similar functions include “Home,” which returns the tray to the center position for reload, and “DriveIncrement,” which drives the machine forward the exact distance for installation of the next 4 panels. Incorporating Vision systems from the autonomous vehicle industry allows for precisely locating the solar panels onto the mounting structure.

The Pallet Management Vehicle (PMV) is used to bridge from current technology with 30 panel pallets located every 50ft to a delivery vehicle that retrieves the panels autonomously. Therefore, it can be used seamlessly with the current worker-based installations to reduce worker fatigue and increase throughput. The PMV is tethered to the base machine. It lifts and tilts a pallet up to 3000lbs. and is self-propelled. The top of the PMV is a landing support for the tray where panels are easily loaded.

ENERGY STORAGE

Utilizing Electric Resistance Heat for Thermal Energy Storage Systems

by James Lewis

With the global movement towards a decarbonized energy grid, sustainable energy technologies are becoming more and more prevalent. As advantageous as sustainable energy is, however, it comes with one significant downfall; it is heavily reliant on environmental conditions. As much as companies are investing in sustainable energy solutions, being able to store the captured energy for later use is critical towards long term success. Energy storage technologies are on a similar development trajectory to improve the viability of sustainable energy solutions.

Long term energy storage technologies come in many forms, including battery storage, compressed air storage, pumped storage, thermal energy storage, and more.

Each concept breaks down into even more specific technologies, all of which aim to achieve a high level of energy efficiency, long storage duration, and low overall cost.

For these primary metrics, one technology that has many advantages is thermal energy storage; in particular, heat storage. As discussed, thermal energy storage is not a one size fits all solution. Under the umbrella term of thermal energy storage, there are many types of media used to store the heat energy, from molten salts and metals to dense media like rocks, sand, and bricks. Regardless of the heated media, all forms of thermal energy storage systems require a heat input. Electric resistance heating is a technology often looked to as a practical way to convert renewable energy into sensible heat, which is then stored in the various mediums.

Electric resistance heating has been available on the market for over one hundred years. While the core technology still adheres to the same principles, recent developments in the capabilities of electric resistance heating have increased its popularity for use in sustainable energy and storage systems. One such advancement

was the development of medium voltage electric resistance heating. Until a decade ago, all electric resistance heaters on the market were rated for low voltage (1000V and less), but advances in coil and dielectric designs has allowed for the new age of electric resistance heating that expanded the technology into medium voltage; specifically, ratings from 1000V up to 7.2kV. Operating at higher voltages significantly reduces the amp draw on the electrical system, reducing the overall infrastructure needed to support the electric heating system. When factoring in heat dissipation from the power switching components and I2R losses through the power wiring, electric resistance heaters already boast a high level of efficiency (higher than 95 percent).

With the significant reduction in amp draw, the system now has fewer power switching components and fewer wires, increasing overall efficiency upwards of 99 percent.

System components and labor and maintenance costs are equally reduced to provide a more advantageous total cost of ownership compared to conventional systems.

Given how electric heaters play a part in the design of future energy storage systems, we must acknowledge their versatility. One notable asset is the obvious ability to run on electrical power. Whether this is off peak grid energy or direct from renewable energy sources, electric resistance heaters can provide a zero-emission solution powered by low-cost renewable energy sources that eliminates both Scope 1 and Scope 2 emissions.

Their versatility provides another advantage compared to the rigidity of the other various thermal energy storage technologies; electric resistance heaters can be integrated into a

variety of product offerings such as duct style heaters, circulation heaters, immersed or embedded heaters, as well as electric heat tracing. This means that energy derived from wind, solar, hydro, or any other renewable source can be distributed through electric heat where it is needed most. The use of molten salts and metals - where high temperatures and harsh corrosive materials may be problematic for many technologies on the market gives electric resistance heaters another advantage: The internal coil design and dielectric barrier must be encapsulated by a metal sheath that can be comprised of high temperature and corrosion resistant alloys. In the case of thermal energy storage systems, process temperatures can easily exceed 1000°F, where utilization of hybrid low and medium voltage systems can be combined to limit overall infrastructure while still providing a robust design that will last decades under the harsh environment.

Also worth considering is how electric heaters are controlled. In most cases, a silicone-controlled rectifier, or SCR, is used. These high precision electronic switching devices are capable of firing an electric heater on and off many times per second. SCRs (thyristors) can uphold the same 95-99 percent efficiency level across all operating cases with 0-100 percent turndown, so these systems only use the energy they need to meet the process demand, and not necessarily the max load the electric heater is capable of handling. From high precision power control to near ideal energy conversion, electric resistance heaters boast many advantages to mitigating losses while simultaneously resisting the extreme environments they are subject to.

As companies around the globe continue to press the boundaries of what sustainable energy and storage technologies are capable of, the value of electric resistance heating cannot be ignored. The technology has proven its longevity as it has become a pivotal part of industrial heating processes for over 100 years. With further advances in design capabilities, electric resistance heating has more to offer to next generation energy storage systems to bring high efficiency, zero emission heat to where it’s needed most.

How sand-based heat storage helps solar power warm up Finnish nights

by Alan Petrillo

T

hese days, when we turn up the heat in our homes and workplaces, we must consider the global impact of burning fuels like oil, gas, coal, and biomass. Our ongoing need for heat presents humanity with a challenge: How can we keep buildings warm now, even as we try to prevent our world from overheating in the future?

It is a daunting question that a Finnish startup is attempting to answer. The company built a pilot system in Tampere, Finland, that can heat buildings with stored solar energy — all day, all night, and all winter long. In an era of complex cleantech solutions (often made from rare and expensive materials), this novel heat storage and distribution system consists of simple ducts, pumps, valves, and 42 metric tons of sand. This novel approach shows the potential for using affordable heat storage to support the utilization of renewable energy.

A small country with large heating needs

To meet the challenge of climate change, the world is investing in new technology to help lessen the use of fossil fuels. These initiatives have largely focused on renewable electric power generation, distribution, and storage.

“When you ask people about cleaner energy, they think of electricity,” says Tommi Eronen, CEO of the startup.

“But we also have to cut emissions from heating.” Out of Finland’s energy-related emissions, 82 percent currently come from the heating of domestic buildings (Figure 1). “We want to replace all of that if we are to have any hope of meeting our global climate goals,” Eronen says.

Think globally, heat locally

As a step toward meeting these ambitious goals, the 3 MWh/100 kW Tampere pilot plant began operation during the winter of 2020–2021.

Figure 2: PNE's Markku Ylönen inspects a Inside the system, electrically powered heat storage medium. Image credit: PNE. resistive heating elements heat air to more than 600°C. (Figure 2) The hot air is circulated through a network of pipes inside of a sand-filled heat storage vessel. After heating the sand, the hot air continues into a heat exchanger, where it heats water that is then circulated through multiple buildings. The sand's heat storage capacity ensures, that even when the resistive elements are cool, the circulating air is still hot enough to keep the water (and buildings) warm.

“We only have pipes, valves, a fan, and an electric heating element. There is nothing special here!” Eronen says, laughing.

A battery for heat made from sand

The sand-based system faces the same core challenges as any other energy infrastructure: It must deliver power to people when they need it, where they need it, and at a manageable price. This means that storing and distributing energy is as important as its generation.

Figure 4: Eronen (foreground) and Ylönen Another factor to account for is the inspecting the ductwork of a Polar Night intermittent nature of daylight and strong Energy heat storage vessel. Image credit: PNE. winds. Energy storage is needed to maintain steady power output throughout the peaks and valleys of renewable inputs. However, even with recent advances in battery technology, storing electric power remains relatively expensive, especially at the scale required for heating buildings. Due to this, the idea was to develop a “battery” that could store heat rather than electricity - a heat battery designed around sand. (Figure 2) “Sand provides four times the energy storage capacity of water,” Eronen says. “Sand is efficient, nontoxic, portable, and cheap!”

The sophisticated analysis behind a simple solution

Cost efficiency is the foundation of the project's value proposition. “As soon as we decided to pursue this idea, we were trying to figure out how the finances looked,” says Eronen. Doing more with less depended on numerical simulation software.

The sheer scale of the sand-based heat storage system makes simulation software indispensable. “We cannot possibly build full-size prototypes to test all of our ideas. We need predictive modeling to answer as many questions as possible, before we commit to assembling all this equipment — and all this sand!” Eronen says. “It is essential for us to use these immensely powerful tools.”

Today: Finland; Tomorrow: the world

Separating the task of heat storage from heat generation and distribution has made the system more efficient and adaptable. The same technology that warms Finland's long, chilly nights can also provide better energy management options to the rest of the world. For instance, affordable thermal storage could help industries and cities capture heat that is currently wasted, as well as balance the inconsistencies of wind and solar power output.

“We have to get away from all kinds of combustion, even biomass,” says Eronen. “We need to protect and restore forests so they can keep removing carbon from the air. Because climate change is happening so fast, we want our ideas to spread as quickly as possible.”

Rising Lithium Prices Fuel EV Anxiety

by Henk Van Alphen

As the price of lithium has skyrocketed over 400 percent in the past year, the demand for lithiumion batteries is more intense than ever. Lithium’s moniker is ‘white petroleum’ due to dramatic need for supplies from the rise of battery giga-factories, electric vehicles, powerwalls and energy storage businesses. Battery makers are budgeting for the rising cost of lithium (a metal crucial to the batteries for electric cars) as they expand their production and over the coming years.

Offering Turnkey Solutions & Engineering Services

“The demand for lithium-ion batteries is higher than ever,” said Chris Berry, President and strategic metal consultant at House Mountain Partners. “Lithium’s lightness helps it store a lot of energy, which is very useful for electronics.” As the price has jumped to nearly $50,000 per ton, some battery manufacturers are raising prices.

The clean energy revolution is well underway with automakers worldwide as the manufacturers grabble with microchip shortages and changing demand from customers. Volvo Cars, for example, has committed to putting one million electrified cars on the road by 2025, with 50 percent of sales volume to be fully electric. France plans to end sales of all gas and diesel cars by 2040, with Germany mandating that all new cars be electric by 2030.

The quest for EV manufacturers to get access to high grade lithium is heated. As the United States and other countries look to disentangle their clean energy supply chains from China currently the leading lithium producer - there’s an urgency to look towards safe, geopolitically friendly lithium-rich countries such as Chile.

Current exploration for lithium in Chile has been concentrated in the Salar de Atacama, the largest salt flat in the country, and Salar de Maricunga, together comprising a property portfolio consisting of 68,800 hectares.

The process of turning lithium into the chemicals that power batteries is not easy. Refining lithium involves chemical processes that, without proper controls, can cause water and soil pollution. Additionally, it can take many years for a new lithium-mining operation to produce battery-grade materials.

While the production of lithium is essential to technology, it can be environmentally damaging. With the primary sources of lithium being hard rock deposits and Salar brines, lithium processing through conventional tactics such as evaporation ponds is inefficient, producing less than half of the lithium being extracted. Other challenges lithium miners face include pollution, high-water use and land use changes. Therefore, as EV makers are sourcing lithium, they should be mindful that their production sources are committed to environmentally sustainable mining practices.

Organizations like Initiative for Responsible Mining Assurance and Responsible Minerals Initiative1 provide the tools and resources focused on minerals supply chain due diligence to produce a comprehensive standard for all mined materials to ensure that EV makers vehicles are truly ‘clean-energy’ vehicles.

Lithium mining companies need to be responsible corporate citizens committed to implementing best environmental practices at all levels of their operations.

That includes building projects together with the communities near operations, protecting nature, and

using the best available techniques and technologies to develop assets. There is no question that the success of a lithium mining business is tied to the success and stability of the company’s host communities and its reputation as a responsible partner in resource development.

Our collective future requires clean air, and our pathway to that environmentally-sound planet demands a global support of economically sound alternative energy plans.

A ‘bet’ on clean energy through investments in renewable energy is a wager that will deliver a cleaner planet that will thrive for current and future generations.

vrs throughout the country have a significant opportunity to pursue a path to meeting climate and decarbonization goals by passing meaningful hydrogen legislation. There is tremendous value in hydrogen energy and storage as a critical part of greening the electric grid and committing to a renewable energy future–both foundational elements of many states’ energy and environmental goals.

The US federal government has sent strong policy signals to the energy industry, regulators, and policy makers that hydrogen should be both taken seriously as a tool in the country’s energy landscape, and developed as a pathway to decarbonize and to reduce overall dependence on hydrocarbons. With more than $9B dedicated to expanding the hydrogen infrastructure and exploring electrolyzer technology through the creation of at least four hydrogen hubs across the U.S., there is a tremendous opportunity to take a significant leap forward in the energy transition.

It seems that, in many instances, hydrogen has taken on a nearly mythical aura; politicians on both sides of the aisle launch existential debates on the potential negative aspects of hydrogen as a viable energy source and part of the renewable energy mix, rather than recognizing the molecule as a tool for cleaner energy. Simply put, hydrogen is just another medium for converting and storing one form of energy into another, very much like an electron.

There seems to be near universal acceptance that batteries, energy storage infrastructure, and electric vehicles (EVs) are important investments for the good of the climate. Implicit in that perspective is that the electricity that powers those cars and batteries will become increasingly cleaner, greener, and carbon free. However, having the infrastructure and market demand is a requisite first step.

Today, however, when most of America charges their phones, EVs, and anything else, the majority of that electricity is derived from natural gas and coal - overwhelmingly so when those devices are charged at night.

We should look at hydrogen the same way we look at electrons: as green as the fuel that is used to make them.

Much like electricity, a traditional way of making hydrogen involves burning coal to heat methane and water to create hydrogen molecules, a process that is both energy inefficient and pollution intensive.

But just like making electricity, this is not the only way to make hydrogen.

Hydrogen can be made without any combustion, meaning no carcinogenic or smog-forming pollution. Hydrogen can be made using renewable methane from wastewater treatment plants or landfills in our cities. Fuel cells can use green electricity and recycled water to create hydrogen through electrolysis, without using any methane at all. When people criticize investments in or incentives for hydrogen production as a “hand out for the oil industry” or a “crutch to prop up a dying industry,” we ignore the many ways clean and green hydrogen can be made and the innovative companies doing it.

Sectors of the economy that are difficult to decarbonize are also some of the most pollution-intensive.

Hydrogen has shown potential to be a far better technology than electrically charged battery packs in fueling long-haul trucks, container ships, construction and industrial equipment, and even trains, all of which use very high torque engines and require a lot of sustained power.

Hydrogen also does a much better job storing energy over days, weeks, and months when compared to batteries. By storing energy as hydrogen, we can take the power of wind or sun and keep it for exactly when we need it, giving us a powerful tool to enhance grid reliability while reducing carbon emissions.

In striving for a cleaner energy future, we have to use every tool at our disposal: renewable power, clean baseload power, batteries, hydrogen, and fuel cells. Pitting technology against technology serves no one but the status quo. Hydrogen, like batteries, is a powerful tool that will help integrate renewable energy across our economy and society. It’s a tool that will lead us into a cleaner and more resilient future.

The 3-micron (µm) film is 40% thinner than SABIC’s 5 µm film, enabling further volume and weight reductions and greater design flexibility through enhanced energy density for the capacitor. Like the 5 µm ELCRES HTV150A film, this thin film maintains stable performance at high operating temperatures from -40°F to 302°F (-40°C to 150°C) and addresses the critical performance gap experienced by traditional polypropylene (PP) films above 275°F (135°C). ELCRES HTV150A dielectric film is also engineered for stable performance at frequencies up to 100kHz, while offering stable capacitance, high insulation resistance, and good dielectric performance (dielectric constant (Dk) of 2.9, dissipation factor (Df ) of 0.002). Other key properties include high breakdown strength over the full temperature range, good self-healing, and excellent adhesion to aluminum and zinc. The film has been validated by customers for use with both film-foil and metalized electrodes. Capacitors built with 3 µm and 5 µm metalized films pass standard electrical and life tests at 302°F (150°C) for 2000 hours with low capacitance change and stable insulation resistance.

Hydrogen-based substation backup power solution

GenCell Energy’s GenCell REX is a hydrogenbased substation backup power solution with the X factor - eXtended runtime. The GenCell REX, an upgrade to the GenCell G5rx, produces emission-free auxiliary electricity for substations during outages that supplements or replaces legacy backup battery systems having limited duration backup power.

Offering an immediate injection of power that keeps circuit breaker “auto reclosers” operational until grid recovery, the GenCell REX complies with stringent regulations requiring utilities to reinforce their backup power. GenCell has enhanced the REX solution with three configurations: 130VDC, 48VDC, and an integrated solution offering a dual output of both 130/48VDC in a single unit. This allows the GenCell REX to concurrently support critical substation loads, internal communications, and SCADA systems that monitor the utilities' operations. The enhanced REX solution improves functionality of the GenCell Remote IoT Manager software by providing improved visibility of the equipment via additional data points that can be accessed by monitoring systems.

Complete hardware and software battery management solution

Sensata Technologies’ new i-BMS battery management system (BMS) for electrified applications up to 60V is a cell chemistry agnostic, compact, integrated BMS developed for the cost-optimized massproduction of applications up to 60V, such as 2-, and 3-wheelers, automated guided vehicles (AGVs), and robotics. Hot swap functionality and parallel battery pack support allow for the ability to quickly exchange depleted batteries with fully charged batteries. While measuring only 65 x 200mm (2.6 x 7.9in), the i-BMS PCB board is equipped with everything required to manage and maintain a battery system, making it a convenient and cost-efficient design for mass production. All critical components are pre-integrated into the system, including a pre-charge circuit, on-board current measurement, MOSFET power switches for battery disconnect, and a DC/DC power supply. The solution features key components that are ASIL C Safety rated and include self-test capabilities for safety critical measurement circuits. The advanced algorithms in Sensata’s BMS software ensure accurate state-ofpower (SOP) predictions based on cell internal resistance, voltage and current constraints, precise state-of-charge (SOC) calculations, and state-of-health (SOH) calculated based on aging effect. In addition, the BMS Creator configuration software allows the battery pack designer to create a unique battery setup by defining application-specific BMS parameters and safety strategies, optimizing battery operation. Other software features include measurement of rate of change of temperature to predict thermal runaway, dynamical regulation of current in extreme thermal conditions, as well as advanced parameter settings for CAN communication.

Flexible, smart inverter

Tigo Energy’s EI Inverter is the centerpiece of the EI Solution. It is extremely flexible, with wide DC operating ranges, and may be AC or DC coupled. When paired with other Tigo products, it provides module-level monitoring, rapid shutdown, and home-energy storage and all commissioned in one app in less than 10 minutes.

Online battery monitoring

Users of application- or customer-specific battery solutions from VARTA now have the option of monitoring their batteries online. As an intelligent extension for more transparency and optimization, the Ellwangen-based technology company has developed a user dashboard that shows all the important KPIs of the battery online, such as the state of charge, health, or the temperature of the battery management system. The storage of this data in the cloud makes it possible to monitor the status of the batteries installed in the various applications at different locations, conveniently from the workplace. The front-end solution can be integrated directly into the device manufacturer's existing solution via API interfaces in order to have a central point of contact for simple and intuitive use.
