UK sets new record for wind power generation

Oxford Battery Energy Storage Project will store surplus renewable power near South-West Oxford and Woodstock, improving grid stability, peak shaving, and reliability, pending IESO approval and Hydro One transmission interconnection in Ontario.

✅ 2028 commercial operation target

✅ Connects to Hydro One transmission line

✅ Peak shaving to stabilize grid costs

A Quebec-based renewable energy company is proposing to build a battery energy storage system in Oxford County near Woodstock.

The Oxford battery energy storage project put forward by Boralex Inc., if granted approval, would be ready for commercial operation in 2028. The facility would be in the Township of South-West Oxford, but also would serve Woodstock businesses and residences, supported by provincial disconnect moratoriums for customers, due to the city’s proximity to the site.

Battery storage systems charge when energy sources produce more energy than customers need, and, complementing Ontario’s energy-efficiency programs across the province, discharge during peak demand to provide a reliable, steady supply of energy.

Darren Suarez, Boralex’s vice-president of public affairs and communications in North America, said, “The system we’re talking about is a very large battery that will help at times when the electric grid has too much energy on the system. We’ll be able to charge our batteries, and when there’s a need, we can discharge the batteries to match the needs of the electric grid.”

South-West Oxford is a region Boralex has pinpointed for a battery storage project. “We look at grid needs as a whole, and where there is a need for battery storage, and we’ve identified this location as being a real positive for the grid, to help with its stability, a priority underscored by the province’s nuclear alert investigation and public safety focus,” Suarez said.

Suarez could not provide an estimated cost for the proposed facility but said the project would add about 75 jobs during the construction phase, in a sector where the OPG credit rating remains stable. Once the site is operational, only one or two employees will be necessary to maintain the facility, he said.

Boralex requires approval from the Independent Electricity System Operator (IESO), the corporation that co-ordinates and integrates Ontario’s electricity system operations across the province, for the Oxford battery energy storage project.

Upon approval, the project will connect with an existing Hydro One transmission line located north of the proposed site. “[Hydro One] has a process to review the project and review the location and ensure we are following safety standards and protocols in terms of integrating the project into the grid, with broader policy considerations like Ottawa’s hydro heritage also in view, but they are not directly involved in the development of the project itself,” Suarez said.

The proposal has been presented to South-West Oxford council. South-West Oxford Mayor David Mayberry said, “(Council) is still waiting to see what permits are necessary to be addressed if the proposal moves forward.”

Mayberry said the Ministry of Natural Resources and Forestry also would be reviewing the proposed project.

Thornton Sand and Gravel, the location of the proposed facility, was viewed positively by Mayberry. “From a positive perspective, they’re not using farmland. There is a plus we’re not using farmland, but there is concern something could leak into the aquifer. These questions need to be answered before it can be to the satisfaction of the community,” Mayberry said.

An open house was held on Sept. 14 to provide information to residents. Suarez said about 50 people showed up and the response was positive. “Many people came out to see what we planned for the project and there was a lot of support for the location because of where it actually is, and how it integrates into the community. It’s considered good use of the land by many of the people that were able to join us on that day,” Suarez said.

The Quebec-based energy company has been operating in Ontario for nearly 15 years and has wind farms in the Niagara and Chatham-Kent regions.

Boralex also is involved in two other battery storage projects in Ontario. The Hagersville project is a 40-minute drive northwest of Hamilton, and the other is in Tilbury, a community in Chatham-Kent. Commercial operation for both sites is planned to begin in 2025.

South-West Oxford and Woodstock will see some financial benefits from the energy storage system, Suarez said.

“It will help to stabilize energy costs. It will contribute to really shaving the most expensive energy on the system off the system. They’re going to take electricity when it’s the least costly, taking advantage of Ontario’s ultra-low overnight pricing options and utilize that least costly energy and displace the most costly energy.”

Canada EV demand surge is driven by record gas prices, zero-emission policies, and tight dealer inventory, while microchip shortages, ZEV mandates abroad, and lithium supply concerns extend wait times for new and used models.

Key Points

Canada EV demand surge is rising interest in zero-emission cars due to high gas prices and limited EV supply.

✅ Gas at $2/litre spurs zero-emission interest

✅ Dealer inventory scarce; waits up to 3 years

✅ Microchip and lithium constraints limit output

Price shock at the pump is driving  Canadians toward buying an ev. But manufacturers are having trouble keeping up with consumer demand, even as the U.S. auto sector pivots to EVs across North America.

In parts of the country, gas prices exceeded $2 per litre last month amid strong global demand for oil combined with Russia's invasion of Ukraine. Halifax-based electric vehicle salesperson Jeremie Bernardin said he's noticed an explosion of interest in zero-emission vehicles since the price of fuel started to take off.

"I think there's a lot of people that were considering electric vehicles for a very long time, and they needed that extra little push," Bernardin, who is also the president of the Electric Vehicle Association of Atlantic Canada, where Atlantic EV demand has lagged the national average, told CTVNews.ca over the phone on Wednesday.

With so few electric vehicles on dealership lots, Canadians looking to buy a brand-new zero-emission car will have to put down a deposit and get onto a waiting list. Bernardin said the wait times can be as long as three years, depending on the manufacturer and the dealership.

Tesla, which makes Canada's best-selling electric car according to the automotive publication Motor Illustrated, says delivery times for its vehicles range between three months to one year, depending on the model. But some manufacturers like Nissan have already completely sold out of their electric vehicle inventory for the 2022 model year, though recent EV assembly deals in Canada aim to expand capacity over time.

Shortages of electric vehicles have been around long before the recent spike in gas prices. In March 2021, a report commissioned by Transport Canada found that more than half of Canadian dealerships had no electric vehicles in stock. The report also found that wait times exceeded six months at 31 per cent of dealerships that had no zero-emission cars in their inventory.

Interest in used electric vehicles has also surged amid the high gas prices. Used car marketplace AutoTrader.ca says searches for electric cars in March 2022 increased 89 per cent compared to the previous year, while the number of inquiries sent to electric vehicle sellers through its platform jumped 567 per cent.

"It's understandable that when the gas prices are expensive, consumers are looking to buy and get into electric vehicles, though upfront cost remains a major barrier for many buyers today," Baris Akyurek, AutoTrader.ca's director of marketing intelligence, told CTVNews.ca in a phone interview on Wednesday.

SUPPLY CHAIN ISSUES PERSIST
The surging interest in electric vehicles also comes at a time when pandemic-induced shortages of microchips have been affecting the automotive industry at large since late 2020. Modern automobiles can have hundreds of microchips that control everything from the air conditioning to the power steering system, and a shortage of these crucial components have resulted in fewer vehicles being manufactured.

"Electric vehicles are subject to supply chain issues, just like anything else. Right now, the COVID pandemic has disrupted global supply chains. The auto industry specifically is seeing a microchip shortage that it's been struggling with for the past year or two. So those things are at play," said Joanna Kyriazis, senior policy advisor with Simon Fraser University’s Clean Energy Canada, in a phone interview with CTVNews.ca on Tuesday.

On top of that, Kyriazis says more than 80 per cent of the world's supply of electric vehicles are shipped to consumers in China and the European Union.

China has a strict zero-emission vehicle (ZEV) mandate that requires automakers to ensure that a certain minimum percentage of their vehicles are electric or hydrogen-powered. In Europe, automakers are also forced to sell more electric vehicles there in order to meet the EU's stringent fleetwide emissions standards, and in Canada, Ottawa is preparing EV sales regulations to guide adoption in the coming years.

"We don't have the same aggressive regulations in place yet to really force automakers to prioritize the Canadian market when they're deciding where to allocate their EV inventory and where to sell EVs," said Kyriazis, though Ottawa's 2035 EV mandate remains debated by some industry observers today.

Kyriazis also said she believes it's possible that a shortage of lithium and other minerals required for battery production could be a potential issue within the next five years.

"But my understanding is that the global market is not hitting a supply crunch just yet," she said. "There could be a near-term supply issue. But we're not there yet."

In order to ensure adequate supply of minerals for battery production, the federal government in its most recent budget committed to providing up to $3.8 billion over eight years to create "Canada's first critical minerals strategy." The strategy is aimed at boosting extraction and production of Canadian nickel, lithium and other minerals used as components in electric vehicles and their batteries, and it aligns with opportunities for Canada-U.S. collaboration as companies electrify.

"Canada has a lot of natural resources and a lot of experience with natural resource extraction. We really can stand to be a leader in battery production," said Harry Constatine, president of the Vancouver Electric Vehicles Association, in an interview with CTVNews.ca over the phone on Monday.

California Iron-Air Battery Storage Project delivers 100-hour long-duration energy storage, supported by a $30 CEC grant, using Form Energy technology at a PG&E substation to boost grid reliability, integrate renewables, and cut fossil reliance.

Key Points

California's 5 MW/500 MWh iron-air battery delivers 100-hour discharge, boosting reliability and renewable integration.

✅ 5 MW/500 MWh iron-air system at a PG&E substation

✅ 100-hour multiday storage enhances grid reliability

✅ CEC $30M grant backs non-lithium, long-duration tech

The California Energy Commission (CEC) has given the green light to a $30 million grant to Form Energy for the construction of an extraordinary long-duration energy storage project that will offer an unparalleled 100 hours of continuous grid discharge.

This ambitious endeavor involves the development of a 5-megawatt (MW) / 500 megawatt-hour iron-air battery storage project, representing the largest long-duration energy storage initiative in California. It also marks the state's inaugural utilization of this cost-effective technology, and joins ongoing procurements by utilities such as San Diego Gas & Electric to expand storage capacity statewide. The project's location is set at a substation owned by the Pacific Gas and Electric Company in Mendocino County, where it will supply power to local residents. The system is scheduled to commence operation by the conclusion of 2025, contributing to grid reliability and showcasing solutions aligned with the state's climate and clean energy objectives.

CEC Chair David Hochschild commented, "A multiday battery system is transformational for California's energy mix. This project will enhance our ability to harness excess renewables during nonpeak hours for use during peak demand, especially as we work toward a goal of 100 percent clean electricity."

This grant award represents one of three approvals within the framework of the CEC's Long-Duration Energy Storage program, a part of Governor Gavin Newsom's historic multi-billion-dollar commitment to combat climate change. This program fosters investment in the demonstration of non-lithium-ion technologies across the state, including green hydrogen microgrids, contributing to the creation of a diverse portfolio of energy storage technologies.

As of August, California had 6,600 MW of battery storage actively deployed statewide, a trend mirrored in regions like Ontario as well, operating within the prevailing industry standard of 4 to 6 hours of discharge. By year-end, this figure is projected to expand to 8,600 MW. Longer-duration storage, spanning from 8 to 100 hours, holds the potential to expedite the state's shift away from fossil fuels while reinforcing grid stability. California estimates that more than 48 gigawatts (GW) of battery storage and 4 GW of long-duration storage will be requisite to achieve the objective of 100 percent clean electricity by 2045.

Energy storage serves as a cornerstone of California's clean energy future, offering a means to capture and store surplus power generated by renewable resources, including emerging virtual power plant models that aggregate distributed assets. The state's battery infrastructure plays a pivotal role during the summer when electricity demand peaks in the early evening hours as solar resources decline, preceding the later surge in wind energy.

Iron-air battery technology operates on the principle of reversible rusting. These battery cells contain iron and air electrodes and are filled with a water-based, nonflammable electrolyte solution. During discharge, the battery absorbs oxygen from the air, converting iron metal into rust. During the charging phase, the application of an electrical current converts the rust back into iron, releasing oxygen. This technology is cost-competitive compared to lithium-ion battery production and complements broader clean energy BESS initiatives seen in New York.

Vineyard Wind I advances as BOEM issues a final environmental impact statement for the 800 MW offshore wind farm south of Martha's Vineyard, delivering clean energy, jobs, and carbon reductions to Massachusetts toward net-zero.

Key Points

An 800 MW offshore wind project near Martha's Vineyard supplying clean power to Massachusetts.

✅ 800 MW capacity; power for 400,000+ homes and businesses

✅ BOEM final EIS; record of decision pending within 30+ days

✅ 1.68M metric tons CO2 avoided annually; jobs and lower rates

Federal environmental officials have completed their review of the Vineyard Wind I offshore wind farm, moving the project that is expected to deliver clean renewable energy to Massachusetts by the end of 2023 closer to becoming a reality.

The U.S. Department of the Interior said Monday morning that its Bureau of Ocean Energy Management completed the analysis it resumed about a month ago, published the project's final environmental impact statement, and said it will officially publish notice of the impact statement in the Federal Register later this week.

"More than three years of federal review and public comment is nearing its conclusion and 2021 is poised to be a momentous year for our project and the broader offshore wind industry," Vineyard Wind CEO Lars Pedersen said. "Offshore wind is a historic opportunity to build a new industry that will lead to the creation of thousands of jobs, reduce electricity rates for consumers and contribute significantly to limiting the impacts of climate change. We look forward to reaching the final step in the federal permitting process and being able to launch an industry that has such tremendous potential for economic development in communities up and down the Eastern seaboard."

The 800-megawatt wind farm planned for 15 miles south of Martha's Vineyard was the first offshore wind project selected by Massachusetts utility companies with input from the Baker administration to fulfill part of a 2016 clean energy law. It is projected to generate cleaner electricity for more than 400,000 homes and businesses in Massachusetts, produce at least 3,600 jobs, reduce costs for Massachusetts ratepayers by an estimated $1.4 billion, and eliminate 1.68 million metric tons of carbon dioxide emissions annually.

Offshore wind power, informed by the U.S. offshore wind outlook, is expected to become an increasingly significant part of Massachusetts' energy mix. The governor and Legislature agree on a goal of net-zero carbon emissions by 2050, but getting there is projected to require having about 25 gigawatts of offshore wind power. That means Massachusetts will need to hit a pace in the 2030s where it has about 1 GW of new offshore wind power on the grid coming online each year.

"I think that's why today's announcement is so historic, because it does represent that culmination of work to understand how to permit and build a cost-effective and environmentally-responsible wind farm that can deliver clean energy to Massachusetts ratepayers, but also just how to do this from start to finish," said Energy and Environmental Affairs Secretary Kathleen Theoharides. "As we move towards our goal of probably [25 GW] of offshore wind by 2050 to hit our net-zero target, this does give us confidence that we have a much clearer path in terms of permitting."

She added, "There's a huge pipeline, so getting this project out really should open the door to the many additional projects up and down the East Coast, such as Long Island proposals, that will come after it."

According to the American Wind Energy Association, there are expected to be 14 offshore projects totaling 9,112 MW of capacity in operation by 2026.

Susannah Hatch, the clean energy coalition director for the Environmental League of Massachusetts and a leader of the broad-based New England for Offshore Wind Regional group, called offshore wind farms like Vineyard Wind "the linchpin of our decarbonization efforts in New England." She said the Biden administration's quick action on Vineyard Wind is a positive sign for the burgeoning sector.

"Moving swiftly on responsibly developed offshore wind is critical to our efforts to mitigate climate change, and offshore wind also provides an enormous opportunity to grow the economy, create thousands of jobs, and drive equitable economic benefits through increased minority economic participation in New England," Hatch said.

With the final environmental impact statement published, Vineyard Wind still must secure a record of decision from BOEM, which processes wind lease requests, an air permit from the Environmental Protection Agency and sign-offs from the U.S. Army Corps of Engineers and the National Marine Fisheries Service to officially clear the way for the project that is on track to be the nation's first utility-scale offshore wind farm. BOEM must wait at least 30 days from the publication of the final environmental impact statement to issue a record of decision.

Project officials have said they expect the final impact statement and then a record of decision "sometime in the first half of 2021." That would allow the project to hit its financial close milestone in the second half of this year, begin on-shore work quickly thereafter, start offshore construction in 2022, begin installing turbines in 2023 and begin exporting power to the grid, marking Vineyard Wind first power, by late 2023, Pedersen said in January.

"Offshore energy development provides an opportunity for us to work with Tribal nations, communities, and other ocean users to ensure all decisions are transparent and utilize the best available science," BOEM Director Amanda Lefton said.

The commercial fishing industry has been among the most vocal opponents of aspects of the Vineyard Wind project and the Responsible Offshore Development Alliance (RODA) has repeatedly urged the new administration to ensure the voices of the industry are heard throughout the licensing and permitting process.

In comments submitted earlier this month in response to a BOEM review of an offshore wind project that is expected to deliver power to New York, including the recent New York offshore wind approval, RODA said the present is "a time of significant confusion and change in the U.S. approach to offshore wind energy (OSW) planning" and detailed mitigation measures it wants to see incorporated into all projects.

"To be clear, none of these requests are new -- nor hardly radical. They have simply been ignored again, and again, and again in a political push/pull between multinational energy companies and the U.S. government, leaving world-famous seafood, and the communities founded around its harvest, off the table," the group said in a press release last week. Some of RODA's suggestions were analyzed as part of BOEM's Vineyard Wind review.

Vineyard Wind has certainly taken a circuitous path to get to this point. The timeline for the project was upended in August 2019 when the Trump administration decided to conduct a much broader assessment of potential offshore wind projects up and down the East Coast, which delayed the project by almost a year.

When the Trump administration delayed its action on a final environmental impact statement last year, Vineyard Wind on Dec. 1 announced that it was pulling its project out of the federal review pipeline in order to complete an internal study on whether the decision to use a certain type of turbine would warrant changes to construction and operations plan. The Trump administration declared the federal review of the project "terminated."

Within two weeks of President Joe Biden being inaugurated, Vineyard Wind said its review determined no changes were necessary and the company resubmitted its plans for review. BOEM agreed to pick up where the Trump administration had left off despite the agency previously declaring its review terminated.

"It would appear that fishing communities are the only ones screaming into a void while public resources are sold to the highest bidder, as BOEM has reversed its decision to terminate a project after receiving a single letter from Vineyard Wind," RODA said.

The final environmental impact statement that BOEM published Monday showed that the federal regulators believe the Vineyard Wind I development as proposed will have "moderate" impacts on commercial fisheries and for-hire recreational fishing outfits, and that the project combined with other factors not related to wind energy development will have "major" impacts on commercial and recreational fishing ventures.

Vineyard Wind pointed Monday to the fishery mitigation agreements it has entered into with Massachusetts and Rhode Island, a fishery science collaboration with the University of Massachusetts Dartmouth's School of Marine Science and Technology, and an agreement with leading environmental organizations around the protection of the endangered right whale.

Responding to concerns about safe navigation among RODA and others in the fishing sector, Vineyard Wind and the four other developers holding leases for offshore wind sites off New England agreed to orient their turbines in fixed east-to-west rows and north-to-south columns spaced one nautical mile apart. Last year, the U.S. Coast Guard concluded that the grid layout was the best way to maintain maritime safety and ease of navigation in the offshore wind development areas south of Martha's Vineyard and Nantucket.

Since a 2016 clean energy law kicked off the state's foray into the offshore wind world, Massachusetts utilities have contracted for a total of about 1,600 MW between two projects, Vineyard Wind I and Mayflower Wind.

A joint venture of Shell and Ocean Winds North America, Mayflower Wind was picked unanimously in 2019 by utility executives to build and operate a wind farm approximately 26 nautical miles south of Martha's Vineyard and 20 nautical miles south of Nantucket, with South Coast construction activity expected as the project progresses. The 804-megawatt project is expected to be operational by December 2025.

Massachusetts and its utilities are expected to go out to bid for up to another 1,600 MW of offshore wind generation capacity later this year using authorization granted by the Legislature in 2018.

The climate policy bill that Gov. Charlie Baker returned to the Legislature with amendments more than a month ago would require that the executive branch direct Massachusetts utilities to buy an additional 2,400 MW of offshore wind power.

U.S. Offshore Wind Power Strategy leverages UK offshore wind lessons, contract auctions, and supply chains to scale renewable energy, build wind farms, cut emissions, create jobs, and modernize the grid to meet 2030 climate goals.

Key Points

U.S. plan to scale offshore wind via UK-style contracts, turbines, and supply chains to meet 2030 clean energy goals

✅ Contract-for-difference price guarantees de-risk projects

✅ Scale turbines and ports to cut LCOE and boost capacity

✅ Build coastal grids, transmission, and workforce by 2030

As President Joe Biden’s administration puts its muscle behind wind power with plans to develop large-scale wind farms along the entire United States coastline, the administration can look at how the windiest nation in Europe is transforming its energy grid for an example of how to proceed.

In the search for renewable sources of energy, the United Kingdom has embraced wind power. In 2020, the country generated as much as 24 percent of its electricity from wind power across the grid — enough to supply 18.5 million homes, according to government statistics. 

With usually reliable winds, the U.K. currently has the highest number of offshore turbines installed in the world, with China at a close second.

Experts and industry leaders say it offers valuable lessons on creating a viable market for wind power at the ambitious scale the Biden administration hopes to meet in order to confront climate change and help transition the U.S. economy to renewable energy.

“The U.S. is going to benefit hugely from the early investment that European governments have put into offshore wind,” said Oliver Metcalfe, a wind power analyst at BloombergNEF in London, an independent research group.

Big American plans
On Oct. 13, the White House announced ambitious offshore wind plans to lease federal waters off of the East and West Coasts and Gulf of Mexico to develop commercial wind farms.

The move is part of Biden’s goal to have 30,000 megawatts of offshore wind power produced in the United States by 2030, with projects such as New York's record-setting approval highlighting the momentum. The White House says that would generate enough electricity to power more than 10 million homes and in the process create 77,000 jobs. 

But there is a chasm between where the U.S. is now and where it wants to be within the next decade when it comes to offshore wind power.

“We’re the first generation to understand the science and implications of climate change and we’re the last generation to be able to do something about it.”

The U.S. is not new to wind power; onshore wind in states such as Texas, Oklahoma and Iowa supplied 8.2 percent of the country’s total electricity generation in 2020, according to the U.S. Department of Energy. 

But despite its long coastlines, offshore wind has been a largely untapped resource in the U.S. With a population of about 332 million people, the U.S. currently has just two operational offshore wind farms — off Rhode Island and Virginia — with the capacity to produce 42 megawatts of electricity between them, far from the 1 gigawatt on-grid milestone many are watching. 

In contrast, the U.K., with a population of 67 million people, has 2,297 offshore wind turbines with the capacity to produce 10,415 megawatts of electricity.

Power station or a park?
Just outside of central Glasgow, the host city for the U.N. climate change conference known as COP26, the fruits of years of effort to move away from fossil fuels can be seen and heard

International financiers, including the World Bank are helping developing countries scale wind projects to meet climate goals.

Whitelee Windfarm, the U.K.’s largest onshore wind farm, spreads across 30 square miles on the Eaglesham Moor and includes more than 80 miles of trails for walking, cycling and horseback riding.

With its 539 megawatt capacity, it generates enough electricity for 350,000 homes — more than half the population of Glasgow. 

On a recent gusty fall day, Ian and Fiona Gardner, both 71, were walking their dogs among the wind farm’s 360-foot-tall turbines  

“This is a major contribution to Scotland, to become independent from oil by 2035,” Ian Gardner, an accountant, said. 

Thanks to the rapid technological advances in turbine technology, this wind farm that was completed in 2009, is now practically old school. The latest crop of onshore turbines typically generate double the current capacity of Whitelee’s turbines.

“It took us 20 years to build 2 gigawatts of power. And we’re going to double that in five  years,” said McQuade, an economist. “We can do that because machines are big, efficient, cheap and the supply chain is there.” 

The biggest operational offshore wind farm in the world right now, Hornsea Project One, is about 75 miles off England’s Yorkshire coast in the North Sea.

Owned and operated by Orsted, a former Danish oil and gas giant, in partnership with Global Infrastructure Partners, its 174 turbines have the capacity to generate 1.2 gigawatts — enough to power over 1 million homes and roughly equivalent to a nuclear power plant. 

Benj Sykes, Vice President of U.K. Offshore Wind at Orsted, called Hornsea One a “game changer” in a recent phone interview, citing it as an example of how the industry has scaled up its output to compete with traditional power plants.

But massive projects like Hornsea One took decades to get up and running, as well as government help. According to Malte Jansen, a research associate at the Centre of Environmental Policy at Imperial College London, the British government helped facilitate a “paradigm shift” in renewable energy in 2013.

The electricity market reform policy set up a framework to incentivize investment in offshore wind farms by creating an auction system that guarantees electricity prices to developers in 15-year contracts, alongside new contract awards that add 10 GW to the U.K. grid. 

This means there is no upside in terms of market price fluctuation, but there is no downside either. The policy essentially “de-risked the investment,” Jansen said.

The state contracts allowed the industry to innovate and learn how to develop even larger and more efficient turbines with blades that stretch as long as 267 feet, about three-quarters the size of a U.S. football field. 

While this approach helped companies and investors, it will also have an unintended beneficiary — the U.S., Metcalfe from BloombergNEF said. 

Developers are “taking the lessons they’ve learned building projects in Europe, the cost reductions that they’ve achieved building projects in Europe and are now bringing those to the U.S. market,” he said.

Floating Solar at Fort Bragg delivers a 1 MW DoD-backed floatovoltaic array on Big Muddy Lake, boosting renewable energy, resilience, and efficiency via water cooling, with Duke Energy and Ameresco supporting backup power.

Key Points

A 1 MW floating PV array on Big Muddy Lake, built by the US Army to boost efficiency, resilience, and backup power.

✅ 1 MW array supplies backup power for training facilities.

✅ Water cooling improves panel efficiency and output.

✅ Partners: Duke Energy, Ameresco; DoD's first floating solar.

Floating solar had a moment in the spotlight over the weekend when the US Army unveiled a new solar plant sitting atop the Big Muddy Lake at Fort Bragg in North Carolina. It’s the first floating solar array deployed by the Department of Defense, and it’s part of a growing current of support in the US for “floatovoltaics” and other innovations like space-based solar research.

The army says its goal is to boost clean energy, support goals in the Biden solar plan for decarbonization, reduce greenhouse gas emissions, and give the nearby training facility a source of backup energy during power outages. The panels will be able to generate about one megawatt of electricity, which can typically power about 190 homes, and, when paired with solar batteries, enhance resilience during extended outages.

The installation, the largest in the US Southeast, is a big win for floatovoltaics, and projects like South Korea’s planned floating plant show global momentum for the technology, which has yet to make a big splash in the US. They only make up 2 percent of solar installations annually in the country, according to Duke Energy, which collaborated with Fort Bragg and the renewable energy company Ameresco on the project, even as US solar and storage growth accelerates nationwide.

Upfront costs for floating solar have typically been slightly more expensive than for its land-based counterparts. The panels essentially sit on a sort of raft that’s tethered to the bottom of the body of water. But floatovoltaics come with unique benefits, complementing emerging ocean and river power approaches in water-based energy. Hotter temperatures make it harder for solar panels to produce as much power from the same amount of sunshine. Luckily, sitting atop water has a cooling effect, which allows the panels to generate more electricity than panels on land. That makes floating solar more efficient and makes up for higher installation costs over time.

And while solar in general has already become the cheapest electricity source globally, it’s pretty land-hungry, so complementary options like wave energy are drawing interest worldwide. A solar farm might take up 20 times more land than a fossil fuel power plant to produce a gigawatt of electricity. Solar projects in the US have already run into conflict with some farmers who want to use the same land, for example, and with some conservationists worried about the impact on desert ecosystems.
