Emera Inc. and National Grid announced a partnership to develop an electricity transmission line linking northern Maine and Maritime Canada to supply energy to the southern New England market.

National Grid will join Emera Inc. and Spectra Energy, who are working to evaluate the feasibility of the Northeast Energy Link, which they say would provide the New England market with new access to a portfolio of existing and future renewable generation developments in both northern Maine and Atlantic Canada.

"National Grid has significant electric transmission experience and a strong market presence in New England," said Chris Huskilson, President and CEO of Emera Inc. "This complements Emera's market position in Atlantic Canada and Maine. Working together with National Grid we intend to play a role in New England's future transmission development plans."

The new transmission infrastructure would be built in a multi-phase project that would initially provide for 660 MW of electricity transfer from Atlantic Canada and northern Maine directly to Massachusetts.

Electricity and water do mix: How electric ships are clearing the air on the B.C. coast

Hybrid Electric Ships leverage marine batteries, LNG engines, and clean propulsion to cut emissions in shipping. From ferries to cargo vessels, electrification and sustainability meet IMO regulations, Corvus Energy systems, and dockside fast charging.

 

Key Points

Hybrid electric ships use batteries with diesel or LNG engines to cut fuel and emissions and meet stricter IMO rules.

✅ LNG or diesel gensets recharge marine battery packs.

✅ Cuts CO2, NOx, and particulate emissions in port and at sea.

✅ Complies with IMO standards; enables quiet, efficient operations.

 

The river is running strong and currents are swirling as the 150-metre-long Seaspan Reliant slides gently into place against its steel loading ramp on the shores of B.C.'s silty Fraser River.

The crew hustles to tie up the ship, and then begins offloading dozens of transport trucks that have been brought over from Vancouver Island.

While it looks like many vessels working the B.C. coast, below decks, the ship is very different. The Reliant is a hybrid, partly powered by electricity, and joins BC Ferries' hybrid ships in the region, the seagoing equivalent of a Toyota Prius.

Down below decks, Sean Puchalski walks past a whirring internal combustion motor that can run on either diesel or natural gas. He opens the door to a gleaming white room full of electrical cables and equipment racks along the walls.

"As with many modes of transportation, we're seeing electrification, from electric planes to ferries," said Puchalski, who works with Corvus Energy, a Richmond, B.C. company that builds large battery systems for the marine industry.

In this case, the batteries are recharged by large engines burning natural gas.

"It's definitely the way of the future," said Puchalski.

The 10-year-old company's battery system is now in use on 200 vessels around the world. Business has spiked recently, driven by the need to reduce emissions, and by landmark projects such as battery-electric high-speed ferries taking shape in the U.S.

"When you're building a new vessel, you want it to last for, say, 30 years. You don't want to adopt a technology that's on the margins in terms of obsolescence," said Puchalski. "You want to build it to be future-proof."

 

Dirty ships

For years, the shipping industry has been criticized for being slow to clean up its act. Most ships use heavy fuel oil, a cheap, viscous form of petroleum that produces immense exhaust. According to the European Commission, shipping currently pumps out about 940 million tonnes of CO2 each year, nearly three per cent of the global total.

That share is expected to climb even higher as other sectors reduce emissions.

When it comes to electric ships, Scandinavia is leading the world. Several of the region's car and passenger ferries are completely battery powered — recharged at the dock by relatively clean hydro power, and projects such as Kootenay Lake's electric-ready ferry show similar progress in Canada.

 

Tougher regulations and retailer pressure

The push for cleaner alternatives is being partly driven by worldwide regulations, with international shipping regulators bringing in tougher emission standards after a decade of talk and study, while financing initiatives are helping B.C. electric ferries scale up.

At the same time, pressure is building from customers, such as Mountain Equipment Co-op, which closely tracks its environmental footprint. Kevin Lee, who heads MEC's supply chain, said large companies are realizing they are accountable for their contributions to climate change, from the factory to the retail floor.

"You're hearing more companies build it into their DNA in terms of how they do business, and that's cool to see," said Lee. "It's not just MEC anymore trying to do this, there's a lot more partners out there."

In the global race to cut emissions, all kinds of options are on the table for ships, including giant kites being tested to harvest wind power at sea, and ports piloting hydrogen-powered cranes to cut dockside emissions.

Modern versions of sailing ships are also being examined to haul cargo with minimal fuel consumption.

But in practical terms, hybrids and, in the future, pure electrics are likely to play a larger role in keeping the propellers turning along Canada's coast, with neighboring fleets like Washington State Ferries' upgrade underscoring the shift.

NY Governor Cuomo Announces Green New Deal Included in 2019 Executive Budget

New York Green New Deal accelerates clean energy and climate action, targeting carbon neutrality with renewable energy, offshore wind, solar, energy storage, and green jobs while advancing environmental justice and economy-wide decarbonization.

 

Key Points

New York's plan for 100% clean power by 2040 and 70% renewables by 2030, with a just transition and green jobs.

✅ 100% carbon-free electricity by 2040; 70% renewables by 2030

✅ 9,000 MW offshore wind and 3,000 MW energy storage targets

✅ Just transition focuses on jobs, equity, and affordability

 

New York Governor Andrew M. Cuomo announced the Green New Deal, a nation-leading clean energy and jobs agenda that will aggressively put New York State on a path to net-zero electricity and economy-wide carbon neutrality, is included in the 2019 Executive Budget. The landmark plan provides for a just transition to clean energy that spurs growth of the green economy and prioritizes the needs of low- to moderate-income New Yorkers.

"Climate change is a reality, and the consequences of delay are a matter of life and death. We know what we must do. Now we have to have the vision, the courage, and the competence to get it done," Governor Cuomo said. "While the federal government shamefully ignores the reality of climate change and fails to take meaningful action, we are launching the first-in-the-nation Green New Deal to seize the potential of the clean energy economy, set nation's most ambitious goal for carbon-free power, and ultimately eliminate our entire carbon footprint."

During Governor Cuomo's first two terms, New York banned fracking of natural gas, committed to phasing out coal power by 2020, mandated 50 percent renewable power by 2030, and established the U.S. Climate Alliance to uphold the Paris Agreement, reflecting the view that decarbonization is irreversible under a clean energy economy. Under the Reforming the Energy Vision agenda, New York has held the largest renewable energy procurements in U.S. history, solar has increased nearly 1,500 percent, and offshore wind is poised to transform the State's electricity supply to be cleaner and more sustainable. Through Governor Cuomo's Green New Deal, New York will take the bold next steps to secure a clean energy future that protects the environment for generations to come while growing the clean energy economy.

 

100 Percent Clean Power by 2040 Coupled with New Nation-leading Renewable Energy Mandates

The Green New Deal will statutorily mandate New York's power be 100 percent carbon-free by 2040, the most aggressive goal in the United States and five years ahead of a target recently adopted by California state policymakers. The cornerstone of this new mandate is a significant increase of New York's successful Clean Energy Standard mandate from 50 percent to 70 percent renewable electricity by 2030. This globally unprecedented ramp-up of renewable energy will include:

  • Quadrupling New York's offshore wind target to 9,000 megawatts by 2035, up from 2,400 megawatts by 2030
  • Doubling distributed solar deployment to 6,000 megawatts by 2025, up from 3,000 megawatts by 2023
  • More than doubling new large-scale land-based wind and solar resources through the Clean Energy Standard
  • Maximizing the contributions and potential of New York's existing renewable resources
  • Deploying 3,000 megawatts of energy storage by 2030, up from 1,500 megawatts by 2025
  • Develop an Implementation Plan to Make New York Carbon Neutral

The Green New Deal will create the State's first statutory Climate Action Council, comprised of the heads of relevant State agencies and other workforce, environmental justice, and clean energy experts to develop a comprehensive plan to make New York carbon neutral by significantly and cost-effectively reducing emissions from all major sources, including electricity, transportation, buildings, industry, commercial activity, and agriculture. The Climate Action Council will consider a range of possible options, including the feasibility of working with the U.S. Climate Alliance to create a new multistate emissions reduction program that covers all sectors of the economy, including transportation and industry, and exploring ways to leverage the successful Regional Greenhouse Gas Initiative to drive transformational investment in the clean energy economy and support a just transition.

At the national level, a historic climate deal is reshaping incentives and standards for clean energy deployment across the country.

The Green New Deal will also include an ambitious strategy to move New York's statewide building stock to carbon neutrality. The agenda includes:

Advancing legislative changes to strengthen building energy codes and establish appliance efficiency standards

Directing State agencies to ensure that their facilities uphold the strongest energy efficiency and sustainability standards

Developing a Net Zero Roadmap to chart a course to statewide carbon neutrality in buildings

A Multibillion Dollar Green New Deal Investment in the Clean Tech Economy that will Reduce Greenhouse Gas Emissions

Demonstrating New York's immediate commitment to implementing the nation's most ambitious clean energy agenda and creating high-quality clean energy jobs, Governor Cuomo is announcing $1.5 billion in competitive awards to support 20 large-scale solar, wind and energy storage projects across upstate New York. These investments will add over 1,650 megawatts of capacity and generate over 3,800,000 megawatt-hours of renewable energy annually - enough to power nearly 550,000 homes and create over 2,600 short and long-term jobs. Combined with the renewable energy projects previously announced under the Clean Energy Standard, New York has now awarded more than $2.9 billion to 46 projects statewide, enough to power over one million households.

The Green New Deal also includes new investments to jumpstart New York's offshore wind energy industry and support the State's world-leading target of 9,000 megawatts by 2035. New York will invest up to $200 million in port infrastructure to match private sector investment in regional development of offshore wind. This multi-location investment represents the nation's largest infrastructure commitment to offshore wind and solidifies New York's position as the hub of the burgeoning U.S. offshore wind industry.

These new investments build upon a $250 million commitment to electric vehicle infrastructure by the New York Power Authority's EVolve program, $3.5 billion in private investment in distributed solar driven by NYSERDA's NY-Sun program, and NY Green Bank transactions mobilizing nearly $1.75 billion in private capital for clean energy projects.

 

A Just Transition to a Clean Energy Economy

Deliver Climate Justice for Underserved Communities: The Green New Deal will help historically underserved communities prepare for a clean energy future and adapt to climate change by:

Giving communities a seat at the table by codifying the Environmental Justice and Just Transition Working Group into law and incorporating it into the planning process for the Green New Deal's implementation.

Directing the State's low-income energy task force to identify reforms to achieve greater impact of the public energy funds expended each year in order to increase the effect of funds and initiatives that target energy affordability to underserved communities.

Directing each of the State's ten Regional Economic Development Councils to develop an environmental justice strategy for their region.

Finance a Property Tax Compensation Fund to Help Communities Transition to the Clean Energy Economy: Governor Cuomo is introducing legislation to finance the State's $70 million Property Tax Compensation Fund to continue helping communities directly affected by the transition away from dirty and obsolete energy industries and toward the new clean energy economy. Specifically, this funding will protect communities impacted by the retirement of conventional power generation facilities.

Protect Labor Rights: To ensure creation of high-quality clean energy jobs, large-scale renewable energy projects supported by the Green New Deal will require prevailing wage, and the State's offshore wind projects will be supported by a requirement for a Project Labor Agreement.

Develop the Clean Tech Workforce: To prepare New York's workforce for the transition, New York State will take new steps to support workforce development, including establishing a New York State Advisory Council on Offshore Wind Economic and Workforce Development, as well as investing in an offshore wind training center that will provide New Yorkers with the skills and safety training required to construct this clean energy technology in New York.   

Richard Kauffman, Chairman of Energy and Finance for New York, said, "Governor Cuomo's Green New Deal will advance New York State further into the clean energy future, and we won't let the Trump Administration push us backwards. Governor Cuomo's new commitments ensure New York is the undisputed national clean energy and climate leader, and we will continue to build upon the foundations of the REV agenda to achieve a sustainable economy and healthy environment for generations of New Yorkers to come."

Alicia Barton, President and CEO, NYSERDA, said, "Climate scientists have made frighteningly clear that averting the worst effects of climate change will require bold action, not incremental steps, and Governor Cuomo's Green New Deal boldly goes where no others have before. His unwavering climate agenda includes the most aggressive clean energy target in U.S. history, the largest commitments to renewable energy and to offshore wind in the nation, a massive mobilization of clean energy jobs and an unprecedented investment in offshore wind port infrastructure. Together these actions make New York the clear national leader in the fight against climate change, and will show the world that New York can and will achieve a clean energy future for the sake of future generations."

DEC Commissioner Basil Seggos said, "The threat of climate change calls for bold action like Governor Cuomo's comprehensive agenda to make New York State carbon neutral. The Green New Deal ensures New York is continuing our nation-leading efforts to capitalize on the economic potential of the clean energy economy, while making sure those most vulnerable to climate change are benefitting from the state's efforts and investments. I look forward to working with my agency and authority partners on the Climate Action Council to develop and implement meaningful solutions to reduce greenhouse gas emissions from all sectors of our economy."  

John B. Rhodes, CEO, Department of Public Service, said, "With this nation-leading Green New Deal, Governor Cuomo puts New York on the path to fully clean electricity and to carbon neutrality with the strongest renewable energy goals in the nation. This will deliver the energy system that New York needs - cost-effective, reliable, and 100% clean.”

Sunrun and Tesla Unveil Texas Power Plant

Sunrun-Tesla Virtual Power Plant Texas leverages residential solar, Tesla Powerwall battery storage, and ERCOT demand response to enhance grid resilience, cut emissions, and supply backup power via a coordinated distributed energy resources network.

 

Key Points

A Texas VPP using residential solar and Tesla Powerwall to aid ERCOT with grid services resilience, and less emissions.

✅ Aggregates Powerwall storage for ERCOT demand response.

✅ Enhances grid reliability with distributed energy resources.

✅ Cuts emissions by shifting solar to peak and outage periods.

 

In a significant development for renewable energy and grid resilience, Sunrun and Tesla have announced a groundbreaking partnership to establish a distributed power plant in Texas. This collaboration represents a major step forward in harnessing solar energy and battery storage, with advances in affordable solar batteries helping to create a more reliable and sustainable power system. The initiative aims to address the growing demand for clean energy solutions while enhancing grid stability and resilience in one of the largest and most energy-dependent states in the U.S.

The new distributed power plant, a joint venture between Sunrun, a leading residential solar provider, and Tesla, renowned for its advanced battery technology and electric vehicles, will leverage the strengths of both companies to transform how energy is generated and used. The project will deploy Tesla's Powerwall battery systems alongside Sunrun's solar panels to create a network of interconnected residential energy storage units. This network will function as a virtual power plant, aligned with emerging peer-to-peer energy sharing models that are capable of providing electricity back to the grid during periods of high demand or outages.

Texas, with its vast and growing population, has faced significant energy challenges in recent years. The state’s power grid, managed by the Electric Reliability Council of Texas (ERCOT), has experienced strain during extreme weather events and high demand periods, and instances of Texas wind curtailment during grid stress, leading to concerns about reliability and stability. The partnership between Sunrun and Tesla seeks to address these concerns by introducing a more flexible and resilient energy solution.

The distributed power plant will consist of thousands of residential solar installations, each equipped with Tesla Powerwall batteries, reflecting the broader trend of pairing storage with solar across the U.S. as it scales. These batteries store excess solar energy generated during the day and release it when needed, such as during peak demand times or power outages. By connecting these systems through advanced software, the project will create a coordinated network of distributed energy resources that can respond dynamically to fluctuations in energy supply and demand.

One of the key benefits of this distributed approach is its ability to enhance grid reliability. Traditional power plants are centralized and can be vulnerable to disruptions, whether from extreme weather, technical failures, or other issues. In contrast, a distributed power plant spreads the generation and storage capacity across numerous locations, a principle echoed by renewable power developers pursuing multi-resource projects today, reducing the risk of widespread outages and increasing the overall resilience of the power grid.

Additionally, the project will contribute to the reduction of greenhouse gas emissions. By increasing the use of solar energy and reducing reliance on fossil fuels, and amid ongoing work to improve solar and wind technologies, the distributed power plant supports Texas’s climate goals and contributes to broader efforts to combat climate change. The integration of renewable energy sources into the grid helps to decrease carbon emissions and promote a cleaner, more sustainable energy system.

The partnership between Sunrun and Tesla also underscores the growing role of technology in transforming the energy landscape. Tesla's Powerwall battery systems represent some of the most advanced energy storage technology available, and amid record solar and storage growth nationwide this decade they showcase the capability to store and manage energy efficiently. Sunrun’s expertise in residential solar installations complements this technology, creating a powerful combination that leverages the latest advancements in clean energy.

The project is expected to deliver several benefits to both individual homeowners and the broader community. Homeowners who participate in the program will have access to solar energy and battery storage at reduced costs, thanks to the economies of scale and innovative financing options provided by Sunrun and Tesla. Additionally, they will have the added security of backup power during outages, contributing to greater energy independence and resilience.

For the broader community, the distributed power plant offers a more reliable and sustainable energy system. The ability to generate and store energy at the residential level reduces the strain on traditional power plants and enhances the overall stability of the grid. Furthermore, the project will contribute to local job creation, as the installation and maintenance of solar panels and battery systems require skilled workers.

As the project moves forward, Sunrun and Tesla will work closely with local stakeholders, regulators, and utility providers to ensure the successful implementation and integration of the distributed power plant. Collaboration with these parties will be essential to addressing any regulatory, technical, or logistical challenges and ensuring that the project delivers its intended benefits.

In conclusion, the partnership between Sunrun and Tesla to create a distributed power plant in Texas represents a significant advancement in clean energy technology and grid resilience. By combining solar power with advanced battery storage, the project aims to enhance grid stability, reduce emissions, and provide reliable energy solutions for homeowners. As Texas continues to face energy challenges, this innovative initiative offers a promising model for the future of distributed energy and highlights the potential for technology-driven solutions to address pressing environmental and infrastructure issues.

Manchin Calls For Stronger U.S. Canada Energy And Mineral Partnership

U.S.-Canada Energy and Minerals Partnership strengthens energy security, critical minerals supply chains, and climate objectives with clean oil and gas, EV batteries, methane reductions, cross-border grid reliability, and allied trade, countering Russia and China dependencies.

 

Key Points

A North American alliance to secure energy, refine critical minerals, cut emissions, and fortify supply chains.

✅ Integrates oil, gas, and electricity trade for reliability

✅ Builds EV battery and critical minerals processing capacity

✅ Reduces methane, diversifies away from Russia and China

 

Today, U.S. Senator Joe Manchin (D-WV), Chairman of the Senate Energy and Natural Resources Committee, delivered the following remarks during a full committee hearing to examine ways to strengthen the energy and mineral partnership between the U.S. and Canada to address energy security and climate objectives.

The hearing also featured testimony from the Honorable Jason Kenney (Premier, Alberta, Canada), the Honorable Nathalie Camden (Associate Deputy Minister of Mines, Ministry of Energy and Natural Resource, Québec, Canada), the Honorable Jonathan Wilkinson (Minister, Natural Resources Canada) and Mr. Francis Bradley (President and CEO, Electricity Canada). Click here to read their testimony.

Chairman Manchin’s remarks can be viewed as prepared here or read below:

Today we’re welcoming our friends from the North, from Canada, to continue this committee’s very important conversation about how we pursue two critical goals – ensuring energy security and addressing climate change.

These two goals aren’t mutually exclusive, and it’s imperative that we address both.

We all agree that Putin has used Russia’s oil and gas resources as a weapon to inflict terrible pain on the Ukrainian people and on Europe.

And other energy-rich autocracies are taking note. We’d be fools to think Xi Jinping won’t consider using a similar playbook, leveraging China’s control over global critical minerals supply chains.

But Putin’s aggression is bringing the free world closer together, setting the stage for a new alliance around energy, minerals, and climate.
Building this alliance should start here in North America. And that’s why I’m excited to hear today about how we can strengthen the energy and minerals partnership between the U.S. and Canada.

I recently had the privilege of being hosted in Alberta by Premier Kenney, where I spent two days getting a better understanding of our energy, minerals, and manufacturing partnership through meetings with representatives from Alberta, Saskatchewan, the Northwest Territories, the federal government, and tribal and industry partners.

Canadians and Americans share a deep history and are natural partners, sharing the longest land border on the planet.

Our people fought side-by-side in two world wars. In fact, some of the uranium used by the Manhattan Project and broader nuclear innovation was mined in Canada’s Northwest Territories and refined in Ontario.

We have cultivated a strong manufacturing partnership, particularly in the automotive industry, with Canada today being our biggest export market for vehicles. Cars assembled in Canada contain, on average, more than 50% of U.S. value and parts.

Today we also trade over 58 terawatt hours of electricity, including green power from Canada across the border, 2.4 billion barrels of petroleum products, and 3.6 trillion cubic feet of natural gas each year.

In fact, energy alone represents $120 billion of the annual trade between our countries. Across all sectors the U.S. and Canada trade more than $2 billion per day.
There is no better symbol of our energy relationship than our interconnected power grid and evolving clean grids that are seamless and integral for the reliable and affordable electricity citizens and industries in both our countries depend on.

And we’re here for each other during times of need. Electricity workers from both the U.S. and Canada regularly cross the border after extreme weather events to help get the power back on.

Canada has ramped up oil exports to the U.S. to offset Russian crude after members of our committee led legislation to cut off the energy purchases fueling Putin’s war machine.

Canada is also a leading supplier of uranium and critical minerals to the U.S., including those used in advanced batteries—such as cobalt, graphite, and nickel.
The U.S-Canada energy partnership is strong, but also not without its challenges, including tariff threats that affect projects on both sides. I’ve not been shy in expressing my frustration that the Biden administration cancelled the Keystone XL pipeline.

In light of Putin’s war in Ukraine and the global energy price surge, I think a lot of us wish that project had moved forward.

But to be clear, I’m not holding this hearing to re-litigate the past. We are here to advance a stronger and cleaner U.S.-Canada energy partnership for the future.
Our allies and trading partners in Europe are begging for North American oil and gas to offset their reliance on Russia.

There is no reason whatsoever we shouldn’t be able to fill that void, and do it cleaner than the alternatives.

That’s because American oil and gas is cleaner than what is produced in Russia – and certainly in Iran and Venezuela. We can do better, and learn from our Canadian neighbors.

On average, Canada produces oil with 37% lower methane emissions than the U.S., and the Canadian federal government has set even more aggressive methane reduction targets.

That’s what I mean by climate and security not being mutually exclusive – replacing Russian product has the added benefit of reducing the emissions profile of the energy Europe needs today.

According to the International Energy Agency, stationary and electric vehicle batteries will account for about half of the mineral demand growth from clean energy technologies over the next twenty years.

Unfortunately, China controls 80% of the world’s battery material processing, 60% of the world’s cathode production, 80% of the world’s anode production, and 75% of the world’s lithium ion battery cell production. They’ve cornered the market.

I also strongly believe we need to be taking national energy security into account as we invest in climate solutions.

It makes no sense whatsoever for us to so heavily invest in electric vehicles as a climate solution when that means increasing our reliance on China, because right now we’re not simultaneously increasing our mining, processing, and recycling capacity at the same rate in the United States.

The Canadians are ahead of us on critical minerals refining and processing, and we have much to learn from them about how they’re able to responsibly permit these activities in timelines that blow ours out of the water.

I’m sure our Canadian friends are happy to export minerals to us, but let me be clear, the United States also needs to contribute our part to a North American minerals alliance.

So I’m interested in discussing how we can create an integrated network for raw minerals to move across our borders for processing and manufacturing in both of our countries, and how B.C. critical minerals decisions may affect that.

I believe there is much we can collaborate on with Canada to create a powerful North American critical minerals supply chain instead of increasing China’s geopolitical leverage.

During this time when the U.S., Canada, and our allies and friends are threatened both by dictators weaponizing energy and by intense politicization over climate issues, we must work together to chart a responsible path forward that will ensure security and unlock prosperity for our nations.

We are the superpower of the world, and blessed with abundant energy and minerals resources. We cannot just sit back and let other countries fill the void and find ourselves in a more dire situation in the years ahead.

We must be leaning into the responsible production of all the energy sources we’re going to need, and strengthening strategic partnerships – building a North American Energy Alliance.

U.S. Announces $28 Million To Advance And Deploy Hydropower Technology

DOE Hydropower Funding advances clean energy R&D, pumped storage hydropower, retrofits for non-powered dams, and fleet modernization under the Bipartisan Infrastructure Law and Inflation Reduction Act, boosting long-duration energy storage, licensing studies, and sustainability engagement.

 

Key Points

A $28M DOE initiative supporting hydropower R&D, pumped storage, retrofits, and stakeholder sustainability efforts.

✅ Funds retrofits for non-powered dams, expanding low-impact supply

✅ Backs studies to license new pumped storage facilities

✅ Engages stakeholders on modernization and environmental impacts

 

The U.S. Department of Energy (DOE) today announced more than $28 million across three funding opportunities to support research and development projects that will advance and preserve hydropower as a critical source of clean energy. Funded through President Biden’s Bipartisan Infrastructure Law, this funding will support the expansion of low-impact hydropower (such as retrofits for dams that do not produce power) and pumped storage hydropower, the development of new pumped storage hydropower facilities, and engagement with key voices on issues like hydropower fleet modernization, sustainability, and environmental impacts. President Biden’s Inflation Reduction Act also includes a standalone tax credit for energy storage, which will further enhance the economic attractiveness of pumped storage hydropower. Hydropower will be a key clean energy source in transitioning away from fossil fuels and meeting President Biden’s goals of 100% carbon pollution free electricity by 2035 through a clean electricity standard policy pathway and a net-zero carbon economy by 2050.

“Hydropower has long provided Americans with significant, reliable energy, which will now play a crucial role in achieving energy independence and protecting the climate,” said U.S. Secretary of Energy Jennifer M. Granholm. “President Biden’s Agenda is funding critical innovations to capitalize on the promise of hydropower and ensure communities have a say in building America’s clean energy future, including efforts to revitalize coal communities through clean projects.” 

Hydropower accounts for 31.5% of U.S. renewable electricity generation and about 6.3% of total U.S. electricity generation, with complementary programs to bolster energy security for rural communities supporting grid resilience, while pumped storage hydropower accounts for 93% of U.S. utility-scale energy storage, ensuring power is available when homes and businesses need it, even as the aging U.S. power grid poses challenges to renewable integration.  

The funding opportunities include, as part of broader clean energy funding initiatives, the following: 

  • Advancing the sustainable development of hydropower and pumped storage hydropower by encouraging innovative solutions to retrofit non-powered dams, the development and testing of technologies that mitigate challenges to pumped storage hydropower deployment, as well as opportunities for organizations not extensively engaged with DOE’s Water Power Technologies Office to support hydropower research and development. (Funding amount: $14.5 million) 
  • Supporting studies that facilitate the FERC licensing process and eventual construction and commissioning of new pumped storage hydropower facilities to facilitate the long-duration storage of intermittent renewable electricity. (Funding amount: $10 million)
  • Uplifting the efforts of diverse hydropower stakeholders to discuss and find paths forward on topics that include U.S. hydropower fleet modernization, hydropower system sustainability, and hydropower facilities’ environmental impact. (Funding amount: $4 million)

Hydropower Plants to Support Solar and Wind Energy

Solar-Wind-Water West Africa integrates hydropower with solar and wind to boost grid flexibility, clean electricity, and decarbonization, leveraging the West African Power Pool and climate data modeling reported in Nature Sustainability.

 

Key Points

A strategy using hydropower to balance solar and wind, enabling reliable, low-carbon electricity across West Africa.

✅ Hydropower dispatch covers solar and wind shortfalls.

✅ Regional interconnection via West African Power Pool.

✅ Cuts CO2 versus gas while limiting new dam projects.

 

Hydropower plants can support solar and wind power, rather unpredictable by nature, in a climate-friendly manner. A new study in the scientific journal Nature Sustainability has now mapped the potential for such "solar-wind-water" strategies for West Africa: an important region where the power sector is still under development, amid IEA investment needs for universal access, and where generation capacity and power grids will be greatly expanded in the coming years. "Countries in West Africa therefore now have the opportunity to plan this expansion according to strategies that rely on modern, climate-friendly energy generation," says Sebastian Sterl, energy and climate scientist at Vrije Universiteit Brussel and KU Leuven and lead author of the study. "A completely different situation from Europe, where power supply has been dependent on polluting power plants for many decades - which many countries now want to rid themselves of."

Solar and wind power generation is increasing worldwide and becoming cheaper and cheaper. This helps to keep climate targets in sight, but also poses challenges. For instance, critics often argue that these energy sources are too unpredictable and variable to be part of a reliable electricity mix on a large scale, though combining multiple resources can enhance project performance.

"Indeed, our electricity systems will have to become much more flexible if we are to feed large amounts of solar and wind power into the grid. Flexibility is currently mostly provided by gas power plants. Unfortunately, these cause a lot of CO2 emissions," says Sebastian Sterl, energy and climate expert at Vrije Universiteit Brussel (VUB) and KU Leuven. "But in many countries, hydropower plants can be a fossil fuel-free alternative to support solar and wind energy. After all, hydropower plants can be dispatched at times when insufficient solar and wind power is available."

The research team, composed of experts from VUB, KU Leuven, the International Renewable Energy Agency (IRENA), and Climate Analytics, designed a new computer model for their study, running on detailed water, weather and climate data. They used this model to investigate how renewable power sources in West Africa could be exploited as effectively as possible for a reliable power supply, even without large-scale storage, in line with World Bank support for wind in developing countries. All this without losing sight of the environmental impact of large hydropower plants.

"This is far from trivial to calculate," says Prof. Wim Thiery, climate scientist at the VUB, who was also involved in the study. "Hydroelectric power stations in West Africa depend on the monsoon; in the dry season they run on their reserves. Both sun and wind, as well as power requirements, have their own typical hourly, daily and seasonal patterns. Solar, wind and hydropower all vary from year to year and may be impacted by climate change, including projections that wind resources shift southward in coming years. In addition, their potential is spatially very unevenly distributed."

West African Power Pool

The study demonstrates that it will be particularly important to create a "West African Power Pool", a regional interconnection of national power grids to serve as a path to universal electricity access across the region. Countries with a tropical climate, such as Ghana and the Ivory Coast, typically have a lot of potential for hydropower and quite high solar radiation, but hardly any wind. The drier and more desert-like countries, such as Senegal and Niger, hardly have any opportunities for hydropower, but receive more sunlight and more wind. The potential for reliable, clean power generation based on solar and wind power, supported by flexibly dispatched hydropower, increases by more than 30% when countries can share their potential regionally, the researchers discovered.

All measures taken together would allow roughly 60% of the current electricity demand in West Africa to be met with complementary renewable sources, despite concerns about slow greening of Africa's electricity, of which roughly half would be solar and wind power and the other half hydropower - without the need for large-scale battery or other storage plants. According to the study, within a few years, the cost of solar and wind power generation in West Africa is also expected to drop to such an extent that the proposed solar-wind-water strategies will provide cheaper electricity than gas-fired power plants, which currently still account for more than half of all electricity supply in West Africa.

Better ecological footprint

Hydropower plants can have a considerable negative impact on local ecology. In many developing countries, piles of controversial plans for new hydropower plants have been proposed. The study can help to make future investments in hydropower more sustainable. "By using existing and planned hydropower plants as optimally as possible to massively support solar and wind energy, one can at the same time make certain new dams superfluous," says Sterl. "This way two birds can be caught with one stone. Simultaneously, one avoids CO2 emissions from gas-fired power stations and the environmental impact of hydropower overexploitation."

Global relevance

The methods developed for the study are easily transferable to other regions, and the research has worldwide relevance, as shown by a US 80% study on high variable renewable shares. Sterl: "Nearly all regions with a lot of hydropower, or hydropower potential, could use it to compensate shortfalls in solar and wind power." Various European countries, with Norway at the front, have shown increased interest in recent years to deploy their hydropower to support solar and wind power in EU countries. Exporting Norwegian hydropower during times when other countries undergo solar and wind power shortfalls, the European energy transition can be advanced.
