COVID-19 Impact on U.S. Wind Industry: disrupting wind power projects, tax credits, and construction timelines, risking rural revenues, jobs, and $35B investments; AWEA seeks Congressional flexibility as OEM shutdowns like Siemens Gamesa intensify delays.

Key Points

Pandemic disruptions threaten 25 GW of projects, $35B investment, rural revenues, jobs, and tax-credit timelines.

✅ 25 GW at risk; $35B investment jeopardized

✅ Rural taxes and land-lease payments may drop $8B

✅ AWEA seeks Congressional flexibility on tax-credit deadlines

In one of the latest examples of the havoc that the novel coronavirus is wreaking on the U.S. economy and the crisis hitting solar and wind sector alike, the American Wind Energy Association (AWEA) -- the national trade association for the U.S. wind industry -- yesterday stated its concerns that COVID-19 will "pose significant challenges to the American wind power industry." According to AWEA's calculations, the disease is jeopardizing the development of approximately 25 gigawatts of wind projects, representing $35 billion in investments, even as wind additions persist in some markets amid the pandemic.

Rural communities, where about 99% of wind projects are located, in particular, face considerable risk. The AWEA estimates that rural communities stand to lose about $8 billion in state and local tax payments and land-lease payments to private landowners. In addition, it's estimated that the pandemic threatens the loss of over 35,000 jobs, and the U.S. wind jobs outlook underscores the stakes, including wind turbine technicians, construction workers, and factory workers.

The development of wind projects is heavily reliant on the earning of tax credits, and debates over a Solar ITC extension highlight potential impacts on wind. However, in order to qualify for the current credits, project developers are bound to begin construction before Dec. 31, 2020. With local and state governments implementing various measures to stop the spread of the virus, the success of project developers' meeting this deadline is dubious, as utility-scale solar construction slows nationwide due to COVID-19. Addressing this and other challenges, the AWEA is turning to the government for help. In the trade association's press release, it states that "to protect the industry and these workers, AWEA is asking Congress for flexibility in allowing existing policies to continue working for the industry through this period of uncertainty."

Illustrating one of the ways in which COVID-19 is affecting the industry, Siemens Gamesa, a global leader in the manufacturing of wind turbines, closed a second Spanish factory this week after learning that a second of its employees had tested positive for the novel coronavirus.

BC Hydro COVID-19 Relief offers electricity bill credits for laid-off workers and small business support, announced by Premier John Horgan, while FortisBC customers face deferrals and billing arrangements across Kelowna, Okanagan, and West Kootenay.

Key Points

BC Hydro COVID-19 Relief gives bill credits to laid-off residents; FortisBC offers deferrals and payment plans.

✅ Credit equals 3x average monthly bill for laid-off BC Hydro users

✅ Small businesses on BC Hydro get three months bill forgiveness

✅ FortisBC waives late fees, no disconnections, offers deferrals

On April 1, B.C. Premier John Horgan announced relief for BC Hydro customers who are facing bills after being laid-off during the economic shutdown due to the COVID-19 epidemic, while the utility also explores time-of-use rates to manage demand.

“Giving people relief on their power bills lets them focus on the essentials, while helping businesses and encouraging critical industry to keep operating,” he said.

BC Hydro residential customers in the province who have been laid off due to the pandemic will see a credit for three times their average monthly bill and, similar to Ontario's pandemic relief fund, small businesses forced to close will have power bills forgiven for three months.

But a large region of the province which gets its power from FortisBC will not have the same bail out.

FortisBC is the electricity provider to the tens of thousands who live and work in the Silmikameen Valley on Highway 3, the city of Kelowna, the Okanagan Valley south from Penticton, the Boundary region along the U.S. border. as well as West Kootenay communities.

“We want to make sure our customers are not worried about their FortisBC bill,” spokesperson Nicole Brown said.

FortisBC customers will still be on the hook for bills despite measures being taken to keep the lights on, even as winter disconnection pressures have been reported elsewhere.

Recent storm response by BC Hydro also highlights how crews have kept electricity service reliable during recent atypical events.

“We’ve adjusted our billing practices so we can do more,” she said. “We’ve discontinued our late fees for the time being and no customer will be disconnected for any financial reason.”

Brown said they will work one-on-one with customers to help find a billing arrangement that best suits their needs, aligning with disconnection moratoriums seen in other jurisdictions.

Those arrangement, she said, could include a “deferral, an equal payment plan or other billing options,” similar to FortisAlberta's precautions announced in Alberta.

Global News inquired with the Premier’s office why FortisBC customers were left out of Wednesday’s announcement and were deferred to the Ministry of Energy, Mines and Petroleum Resources.

The Ministry referred us back to FortisBC on the issue and offered no other comment, even as peak rates for self-isolating customers remained unchanged in parts of Ontario.

“We’re examining all options of how we can further help our customers and look forward to learning more about the program that BC Hydro is offering,” Brown said.

Disappointed FortisBC customers took to social media to vent about the disparity.

Utility Battery Storage Rankings measure grid-connected capacity, not ownership, highlighting MW, MWh, and watts per customer across PJM, MISO, and California IOUs, featuring Duke Energy, IPL, ancillary services, and frequency regulation benefits.

Key Points

Rankings that track energy storage connected to utility grids, comparing MW, MWh, and W/customer rather than ownership.

✅ Ranks by MW, MWh, and watts per customer, not asset ownership

✅ Highlights PJM, MISO cases and California IOUs' deployments

✅ Examples: Duke Energy, IPL, IID; ancillary services, frequency response

The rankings do not tally how much energy storage a utility built or owns, but how much was connected to their system. So while IPL built and owns the storage facility in its territory, Duke does not own the 16 MW of storage that connected to its system in 2016. Similarly, while California’s utilities are permitted to own some energy storage assets, they do not necessarily own all the storage facilities connected to their systems.

Measured by energy (MWh), IPL ranked fourth with 20 MWh, and Duke Energy Ohio ranked eighth with 6.1 MWh.

Ranked by energy storage watts per customer, IPL and Duke actually beat the California utilities, ranking fifth and sixth with 42 W/customer and 23 W/customer, respectively.

Duke ready for next step

Given Duke’s plans, including projects in Florida that are moving ahead, the utility is likely to stay high in the rankings and be more of a driving force in development. “Battery technology has matured, and we are ready to take the next step,” Duke spokesman Randy Wheeless told Utility Dive. “We can go to regulators and say this makes economic sense.”

Duke began exploring energy storage in 2012, and until now most of its energy storage efforts were focused on commercial projects in competitive markets where it was possible to earn revenues. Those included its 36 MW Notrees battery storage project developed in partnership with the Department of Energy in 2012 that provides frequency regulation for the Electric Reliability Council of Texas market and two 2 MW storage projects at its retired W.C. Beckjord plant in New Richmond, Ohio, that sells ancillary services into the PJM Interconnection market.

On the regulated side, most of Duke’s storage projects have had “an R&D slant to them,” Wheeless said, but “we are moving beyond the R&D concept in our regulated territory and are looking at storage more as a regulated asset.”

“We have done the demos, and they have proved out,” Wheeless said. Storage may not be ready for prime time everywhere, he said, but in certain locations, especially where it can it can be used to do more than one thing, it can make sense.

Wheeless said Duke would be making “a number of energy storage announcements in the next few months in our regulated states.” He could not provide details on those projects.

More flexible resources
Location can be a determining factor when building a storage facility. For IPL, serving the wholesale market was a driving factor in the rationale to build its 20 MW, 20 MWh storage facility in Indianapolis.

IPL built the project to address a need for more flexible resources in light of “recent changes in our resource mix,” including decreasing coal-fired generation and increasing renewables and natural gas-fired generation, as other regions plan to rely on battery storage to meet rising demand, Joan Soller, IPL’s director of resource planning, told Utility Dive in an email. The storage facility is used to provide primary frequency response necessary for grid stability.

The Harding Street storage facility in May. It was the first energy storage project in the Midcontinent ISO. But the regulatory path in MISO is not as clear as it is in PJM, whereas initiatives such as Ontario storage framework are clarifying participation. In November, IPL with the Federal Energy Regulatory Commission, asking the regulator to find that MISO’s rules for energy storage are deficient and should be revised.

Soller said IPL has “no imminent plans to install energy storage in the future but will continue to monitor battery costs and capabilities as potential resources in future Integrated Resource Plans.”

California legislative and regulatory push

In California, energy storage did not have to wait for regulations to catch up with technology. With legislative and regulatory mandates, including CEC long-duration storage funding announced recently, as a push, California’s IOUs took high places in SEPA’s rankings.

Southern California Edison and San Diego Gas & Electric were first and fourth (63.2 MW and 17.2 MW), respectively, in terms of capacity. SoCal Ed and SDG&E were first and second (104 MWh and 28.4 MWh), respectively, and Pacific Gas and Electric was fifth (17 MWh) in terms of energy.

But a public power utility, the Imperial Irrigation District (IID), ended up high in the rankings – second in capacity (30 MW) and third  in energy (20 MWh) – even though as a public power entity it is not subject to the state’s energy storage mandates.

But while IID was not under state mandate, it had a compelling regulatory reason to build the storage project. It was part of a settlement reached with FERC over a September 2011 outage, IID spokeswoman Marion Champion said.

IID agreed to a $12 million fine as part of the settlement, of which $9 million was applied to physical improvements of IID’s system.

IID ended up building a 30 MW, 20 MWh lithium-ion battery storage system at its El Centro generating station. The system went into service in October 2016 and in May, IID used the system’s 44 MW combined-cycle natural gas turbine at the generating station.

Passing savings to customers
The cost of the storage system was about $31 million, and based on its experience with the El Centro project, Champion said IID plans to add to the existing batteries. “We are continuing to see real savings and are passing those savings on to our customers,” she said.

Champion said the battery system gives IID the ability to provide ancillary services without having to run its larger generation units, such as El Centro Unit 4, at its minimum output. With gas prices at $3.59 per million British thermal units, it costs about $26,880 a day to run Unit 4, she said.

IID’s territory is in southeastern California, an area with a lot of renewable resources. IID is also not part of the California ISO and acts as its own balancing authority. The battery system gives the utility greater operational flexibility, in addition to the ability to use more of the surrounding renewable resources, Champion said.

In May, IID’s board gave the utility’s staff approval to enter into contract negotiations for a 7 MW, 4 MWh expansion of its El Centro storage facility. The negotiations are ongoing, but approval could come in the next couple months, Champion said.

The heart of the issue, though, is “the ability of the battery system to lower costs for our ratepayers,” Champion said. “Our planning section will continue to utilize the battery, and we are looking forward to its expansion,” she said.” I expect it will play an even more important role as we continue to increase our percentage of renewables.”

France Diesel Prices at Pre-Ukraine Levels reflect energy market stabilization as supply chains adapt and subsidies help; easing fuel costs, inflation, and logistics burdens for households, transport firms, and the wider economy.

Key Points

They mark normalization as oil supply stabilizes, easing fuel costs and logistics expenses for consumers and firms.

✅ Lower transport and logistics operating costs

✅ Softer inflation and improved household budgets

✅ Market stabilization amid adjusted oil supply chains

In a significant development for French consumers and businesses alike, diesel prices in France have recently fallen back to levels last seen before the Ukrainian conflict began, mirroring European gas prices returning to pre-war levels across the region. This drop comes as a relief to many who have been grappling with volatile energy costs and their impact on the cost of living and business operations. The return to lower diesel prices is a noteworthy shift in the energy landscape, with implications for the French economy, transportation sector, and broader European market.

Context of Rising Diesel Prices

The onset of the Ukrainian conflict in early 2022 triggered a dramatic increase in global energy prices, including diesel. The conflict's disruption of supply chains, coupled with sanctions on Russian oil and gas exports, contributed to a steep rise in fuel prices across Europe, prompting the EU to weigh emergency electricity price measures to shield consumers. For France, this meant that diesel prices soared to unprecedented levels, putting significant pressure on consumers and businesses that rely heavily on diesel for transportation and logistics.

The impact was felt across various sectors. Transportation companies faced higher operational costs, which were often passed down to consumers in the form of increased prices for goods and services. Additionally, higher fuel costs contributed to broader inflationary pressures, with EU inflation hitting lower-income households hardest, affecting household budgets and overall economic stability.

Recent Price Trends and Market Adjustments

The recent decline in diesel prices in France is a welcome reversal from the peak levels experienced during the height of the conflict. Several factors have contributed to this price reduction. Firstly, there has been a stabilization of global oil markets as geopolitical tensions have somewhat eased and supply chains have adjusted to new realities. The gradual return of Russian oil to global markets, albeit under complex sanctions and trading arrangements, has also played a role in moderating prices.

Moreover, France's strategic reserves and diversified energy sources have helped cushion the impact of global price fluctuations. The French government has also implemented measures to stabilize energy prices, including subsidies and tax adjustments, and a new electricity pricing scheme to satisfy EU concerns, which have helped alleviate some of the financial pressure on consumers.

Implications for the French Economy

The return to pre-conflict diesel price levels brings several positive implications for the French economy. For consumers, the decrease in fuel prices means lower transportation costs, which can ease inflationary pressures and improve disposable income, and, alongside the EDF electricity price deal, reduce overall utility burdens for households. This is particularly beneficial for households with long commutes or those relying on diesel-powered vehicles.

For businesses, especially those in the transportation and logistics sectors, the drop in diesel prices translates into reduced operational costs. This can help lower the cost of goods and services, potentially leading to lower prices for consumers and improved profitability for businesses. In a broader sense, stabilized fuel prices can contribute to overall economic stability and growth, as lower energy costs can support consumer spending and business investment.

Environmental and Policy Considerations

While the decrease in diesel prices is advantageous in the short term, it also raises questions about long-term energy policy and environmental impact, with the recent crisis framed as a wake-up call for Europe to accelerate the shift away from fossil fuels. Diesel, as a fossil fuel, continues to pose environmental challenges, including greenhouse gas emissions and air pollution. The drop in prices might inadvertently discourage investments in cleaner energy alternatives, such as electric and hybrid vehicles, which are crucial for achieving long-term sustainability goals.

In response, there is a growing call for continued investment in renewable energy and energy efficiency measures. France has been actively pursuing policies to reduce its reliance on fossil fuels and increase the adoption of cleaner technologies, amid ongoing EU electricity reform debates with Germany. The government’s support for green energy initiatives and incentives for low-emission vehicles will be essential in balancing short-term benefits with long-term environmental objectives.

Conclusion

The recent return of French diesel prices to pre-Ukrainian conflict levels marks a significant shift in the energy market, offering relief to both consumers and businesses. While this decline brings immediate financial benefits and supports economic stability, it also underscores the ongoing need for a strategic approach to energy policy and environmental sustainability. As France navigates the evolving energy landscape, the focus will need to remain on fostering a transition towards cleaner energy sources while managing the economic and environmental impacts of fuel price fluctuations.

Polycrystalline Tin Selenide Thermoelectrics enable waste heat recovery with ZT 3.1, matching single crystals while cutting costs, powering greener car engines, industrial furnaces, and thermoelectric generators via p-type and emerging n-type designs.

Key Points

Low-cost tin selenide devices that turn waste heat into power, achieving ZT 3.1 and enabling p-type and n-type modules.

✅ Oxygen removal prevents heat-leaking tin oxide grain skins.

✅ Polycrystalline ingots match single-crystal ZT 3.1 at lower cost.

✅ N-type tin selenide in development to pair with p-type.

So-called thermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, providing what seems like a free lunch. But despite helping power the Mars rovers, the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermoelectrics that work just as well as the pricey kind. The work could pave the way for a new generation of greener car engines, industrial furnaces, and other energy-generating devices.

“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist at Beihang University who was not involved with the work. He notes there are still a few more steps to take before these materials can become high-performing thermoelectric generators. However, he says, “I think this will be used in the not too far future.”

Thermoelectrics are semiconductor devices placed on a hot surface, like a gas-powered car engine or on heat-generating electronics using thin-film converters to capture waste heat. That gives them a hot side and a cool side, away from the hot surface. They work by using the heat to push electrical charges from one to the other, a process of turning thermal energy into electricity that depends on the temperature gradient. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.

 Over the past 2 decades, researchers have produced thermoelectric materials with increasing ZTs, while related advances such as nighttime solar cells have broadened thermal-to-electric concepts. The record came in 2014 when Mercouri Kanatzidis, a materials scientist at Northwestern University, and his colleagues came up with a single crystal of tin selenide with a ZT of 3.1. Yet the material was difficult to make and too fragile to work with. “For practical applications, it’s a non-starter,” Kanatzidis says.

So, his team decided to make its thermoelectrics from readily available tin and selenium powders, an approach that, once processed, makes grains of polycrystalline tin selenide instead of the single crystals. The polycrystalline grains are cheap and can be heated and compressed into ingots that are 3 to 5 centimeters long, which can be made into devices. The polycrystalline ingots are also more robust, and Kanatzidis expected the boundaries between the individual grains to slow the passage of heat. But when his team tested the polycrystalline materials, the thermal conductivity shot up, dropping their ZT scores as low as 1.2.

In 2016, the Northwestern team discovered the source of the problem: an ultrathin skin of tin oxide was forming around individual grains of polycrystalline tin selenide before they were pressed into ingots. And that skin acted as an express lane for the heat to travel from grain to grain through the material. So, in their current study, Kanatzidis and his colleagues came up with a way to use heat to drive any oxygen away from the powdery precursors, leaving pristine polycrystalline tin selenide, whereas other devices can generate electricity from thin air using ambient moisture.

The result, which they report today in Nature Materials, was not only a thermal conductivity below that of single-crystal tin selenide but also a ZT of 3.1, a development that echoes nighttime renewable devices showing electricity from cold conditions. “This opens the door for new devices to be built from polycrystalline tin selenide pellets and their applications to be explored,” Kanatzidis says.

Getting through that door will still take some time. The polycrystalline tin selenide the team makes is spiked with sodium atoms, creating what is known as a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.

Zhao’s team recently reported making an n-type single-crystal tin selenide by spiking it with bromine atoms. And Kanatzidis says his team is now working on making an n-type polycrystalline version. Once n-type and p-type tin selenide devices are paired, researchers should have a clear path to making a new generation of ultra-efficient thermoelectric generators. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial furnaces to scavenge energy from some of the 65% of fossil fuel energy that winds up as waste heat.

Champlain Hudson Power Express Converter Station brings Canadian hydropower via HVDC to Queens, converting 1,250 MW to AC for New York City's grid, replacing a retired fossil site with a zero-emission, grid-scale clean energy hub.

Key Points

A Queens converter turning 1,250 MW HVDC hydropower into AC for NYC's grid, repurposing an Astoria fossil site.

✅ 340-mile underwater/underground HVDC link from Quebec to Queens

✅ 1,250 MW DC-AC conversion feeding directly into NY grid by 2026

✅ Replaces Astoria oil site; supports NY's 70% renewables by 2030

New York Governor Kathy Hochul has announced the start of construction on the converter station of the Champlain Hudson Power Express transmission line, a project to bring electricity generated from Canadian hydropower to New York City.

The 340 mile (547 km) transmission line is a proposed underwater and underground high-voltage direct current power transmission line to deliver the power from Quebec, Canada, to Queens, New York City. The project is being developed by Montreal-based public utility Hydro-Quebec (QBEC.UL) and its U.S. partner Transmission Developers, while neighboring New Brunswick has signed NB Power deals to bring more Quebec electricity into the province.

The converter station for the line will be the first-ever transformation of a fossil fuel site into a grid-scale zero-emission facility in New York City, its backers say.

Workers have already removed six tanks that previously stored 12 million gallons (45.4 million liters) of heavy oil for burning in power plants and nearly four miles (6.44 km) of piping from the site in the Astoria, Queens neighborhood, echoing Hydro-Quebec's push to wean the province off fossil fuels as regional power systems decarbonize.

The facility is expected to begin operating in 2026, even as the Ontario-Quebec power deal was not renewed elsewhere in the region. Once the construction is completed, it will convert 1,250 megawatts of energy from direct current to alternating current power that will be fed directly into the state's power grid, helping address transmission constraints that have impeded incremental Quebec-to-U.S. power deliveries.

“Renewable energy plays a critical role in the transformation of our power grid while creating a cleaner environment for our future generations,” Hochul said. The converter station is a step towards New York’s target for 70% of the state’s electricity to come from renewable sources by 2030, as neighboring Quebec has closed the door on nuclear power and continues to lean on hydropower.
