Every American family—whether they live in a bustling hub like Atlanta, Georgia, or a frontier city like Dillingham, Alaska—should have access to reliable, affordable electricity. And as the climate crisis intensifies, causing more extreme weather events, our country’s most isolated, remote communities will likely face higher energy costs and more power outages, which can cut off vital services like clean water and heat.
That’s why the U.S. Department of Energy’s (DOE) Water Power Technologies Office (WPTO) works with people from big cities to remote villages, as well as the hydropower industry, to help build cleaner, more resilient American communities—with hydropower. This National Hydropower Day, explore a few of the ways WPTO is helping build cleaner communities and making important contributions toward the United States’ goals of achieving a carbon-free electricity sector by 2035 and net-zero-emissions economy by 2050.
Supporting the Clean Energy Transition in Remote and Island Communities
Through the Energy Transitions Initiative Partnership Project (ETIPP), DOE offices, including WPTO, partnered with 11 remote and island communities in 2021 and another 12 in 2022 to help address their local energy resilience challenges.

Twelve more communities are charting their path to a more resilient energy future through the U.S. Department of Energy (DOE) Energy Transitions Initiative Partnership Project. These ETIPP projects are funded by the DOE Office of Energy Efficiency and Renewable Energy’s Energy Transitions Initiative, Geothermal Technologies Office, Solar Energy Technologies Office, Water Power Technologies Office, and Wind Energy Technologies Office.

Many of these ETIPP communities are likely to experience more extreme weather events that can disrupt vulnerable energy systems. But because hydropower offers a reliable and affordable path to greater resiliency, various communities are looking to this dependable renewable energy source to increase their energy independence and security. In Puerto Rico, Cooperativa Hidroelectrica de la Montana members plan to build a microgrid—a smaller grid designed to serve a specific area, like a single city—around their hydropower facility. The project will help deliver more cost-effective, reliable energy to residents across four remote, inland mountain communities and create local jobs, too.
Thousands of miles away, in Dillingham, Alaska, residents pay high diesel prices. To offset some of the financial and environmental burdens associated with using diesel, community leaders will engage experts working with ETIPP to explore the impact and benefits of building a hydroelectric project on the Nuyakuk River so the town can access local, affordable, renewable power.
Incentivizing the Production of Electricity from Hydropower
Today, most U.S. dams do not produce power. Adding generation equipment to these sites could add up to 12 gigawatts of new hydropower capacity to the U.S. electric system and provide reliable, affordable power to communities, including those with inadequate electric service.
The Hydroelectric Production Incentive Program incentivizes developers to pursue this potential resource by providing funding for projects adding hydroelectric power generating capabilities to existing dams and other water infrastructure throughout the United States. In Fiscal Year 2020, WPTO distributed $7 million in incentive payments to 42 hydroelectric facilities across 18 states through this program.
Enhancing Hydropower Flexibility and Overall Grid Resilience
WPTO also supports hydropower projects that aim to improve operational flexibility, value, and overall grid resilience. In 2021, WPTO selected three industry partners to receive technical assistance for projects focused on improving hydropower’s value through informed decision-making. These project teams are working to evaluate the benefits of adding hydrogen technologies to existing hydropower facilities, strengthen the ability of production models to assess hydropower’s value, and improve hydropower operations and dispatch planning using inflow forecasting tools.
Another project supported through WPTO’s HydroWIRES Initiative demonstrated how hydropower—especially small hydropower—could provide electricity during regional grid disruptions. After a power outage left many Idaho residents without electricity in freezing temperatures, Idaho Falls Power, in partnership with Idaho National Laboratory, analyzed how the utility’s five small hydropower plants could help keep electricity flowing. These first-of-a-kind tests showed that small hydropower plants, combined with energy storage, could provide critical backup power for customers.
While hydropower comes with big energy benefits—like black start capabilities and on-demand power—these facilities can provide even more opportunities to build cleaner communities. Hydropower can, for example, help communities manage and store water supplies, irrigate farms with clean energy, restore and clean up the environment, and power wastewater treatment plants. WPTO is helping us understand the great potential of these alternative hydropower opportunities.
And while we are already seeing the impact of the work WPTO is funding to develop and advance hydropower, we continue to build on this portfolio. This month, we announced several new major funding initiatives through our Hydropower Program to reduce environmental impacts, advance technologies for non-powered dams, and expand on hydropower’s grid activities through pumped storage innovation.
With traditional hydroelectric production and beyond, hydropower can help provide American communities with the support they need to become clean energy leaders. On this National Hydropower Day, it’s clear hydropower is already helping build the clean energy future we need—one community at a time.
