Hydropower Deadline Bill Reaches Trump After 394-14 House Vote

WASHINGTON, D.C. Congress has sent President Trump a hydropower deadline bill that would give older Federal Energy Regulatory Commission licensed projects up to six more years to start construction, a narrow permitting change supporters say could unlock nearly 40 stalled projects and more than 2.5 gigawatts of baseload power.

The House passed S. 1020, known by supporters as the Build More Hydro bill, on April 21 under suspension of the rules. The Clerk of the House recorded a 394-14 vote, with 186 Republicans, 207 Democrats, and one independent voting yes.

The bill is now at the president's desk after the Senate passed it by unanimous consent in July 2025, according to Sen. Steve Daines' office. The policy fight is not over a new spending program. It is over how much extra time FERC should be able to give hydropower developers that already hold federal licenses but missed, or are close to missing, construction deadlines.

The Story So Far

Under current law, section 13 of the Federal Power Act requires a licensee to start construction within the time fixed in its license, which cannot be more than two years from the license date. The U.S. Code says FERC may extend the commencement period for no more than eight additional years.

S. 1020 would add another layer for a defined group of projects. The enrolled bill says a covered project means a hydropower project for which FERC issued a license before March 13, 2020. On request from a licensee, FERC could grant more time after reasonable notice and for good cause shown.

The extra period would be capped at six years beyond the eight years already allowed under the Federal Power Act. The bill requires that extension to come in no more than three consecutive two-year periods, according to the enrolled text posted by Congress.gov.

The bill also contains a reinstatement provision. If the commencement period for a covered license expired after December 31, 2023 and before the bill becomes law, FERC may reinstate that license, with the new extension running from the date the prior period expired.

That makes the bill a deadline relief measure, not a federal construction order. It does not automatically approve a new dam, provide direct federal funding, or erase existing license conditions. It gives FERC discretion to keep certain older licensed projects alive if the agency finds good cause.

What's Happening Now

Rep. Dan Newhouse, R-Wash., said his House companion was H.R. 2072 and that the Senate vehicle, S. 1020, is now the version headed to Trump. His office said the House vote was 394-14 and described the bill as a way to move licensed hydropower projects past delays tied to construction timing.

Newhouse's office said the measure would allow construction of nearly 40 projects totaling more than 2.5 gigawatts of baseload power. The office also said roughly 100 megawatts of hydropower had been put on hold since S. 1020 was introduced, with another 36 megawatts headed into limbo by year-end absent congressional action.

Those project counts and megawatt figures come from Newhouse's office, not a project-by-project FERC docket review. The enrolled bill itself does not list the projects that might seek extensions.

House Energy and Commerce Chairman Brett Guthrie, R-Ky., framed the vote as a permitting measure for grid reliability. The committee said the bill would let FERC extend construction deadlines for hydropower projects in communities across the country.

Committee Energy Subcommittee Chairman Bob Latta, R-Ohio, pointed to pandemic-era supply chain disruptions and shutdowns as a reason for additional deadline flexibility. His statement said hydropower provides reliable baseload power to roughly 30 million homes and businesses and nearly 40 percent of black start capacity, the ability to restart parts of the grid after a blackout.

The Conservative View

Republican supporters are presenting the bill as part of a broader domestic energy agenda. Daines said the legislation would help revive projects while adding reliable generation to the grid.

That argument rests on a familiar conservative energy frame: permitting deadlines and procedural limits can strand private investment even after a project receives a federal license. For those supporters, the question is not whether hydropower should face review. It is whether projects licensed before the pandemic should lose their chance to build because the clock kept running while supply chains and construction schedules were disrupted.

Newhouse made that case in direct economic terms. He said the legislation would support baseload generation, improve reliability, and lower energy prices by helping nearly 40 projects move forward.

The Progressive View

The vote record shows broad Democratic support, with every Democrat who voted recorded as a yes by the Clerk of the House. That matters because hydropower sits at an unusual intersection in energy politics: it is renewable electricity, but dams can also raise environmental, fish passage, tribal, recreation, and river management concerns.

The bill's structure appears designed to narrow that conflict. It does not create a blanket exemption from FERC review. It applies only to projects that already received FERC licenses before March 13, 2020, and it preserves an agency decision point by requiring a licensee request, reasonable notice, and good cause shown.

For Democrats who support additional clean electricity but remain cautious about dam impacts, that distinction is central. The House vote suggests most Democrats treated the measure as a timing fix for already licensed projects, not as a rewrite of environmental law.

Other Perspectives

The opposition came from inside the Republican conference. The Clerk recorded 14 Republican no votes, zero Democratic no votes, and 22 members not voting. No primary-source floor statement from a no-voting member was found in this review, so the public record does not show a single stated reason shared by the dissenting bloc.

Fiscal conservatives and libertarian-leaning members sometimes object to energy bills when they believe Congress is extending special treatment to a favored industry or interfering with agency deadlines. That broader concern is relevant to the vote pattern, but the available primary record for S. 1020 shows only the names and party breakdown of the no votes, not their reasoning.

The industry view is more direct. Newhouse's office listed the National Hydropower Association, the American Public Power Association, Northwest RiverPartners, and several Pacific Northwest transportation and agriculture groups among supporters. That coalition reflects hydropower's role in electricity, irrigation, flood control, navigation, and regional economic planning.

Economic Implications

Hydropower is a small share of total U.S. electricity, but it remains one of the country's largest renewable sources. The U.S. Energy Information Administration says total U.S. utility-scale electricity generation was about 4.43 trillion kilowatthours in 2025. Conventional hydropower produced about 6 percent of total utility-scale generation and about 23 percent of renewable utility-scale generation.

EIA data also shows why timing matters. Hydropower generation fell to 241 billion kilowatthours in 2024, the lowest level since at least 2010, according to the agency. EIA's May 2025 Short-Term Energy Outlook expected hydropower generation to rise 7.5 percent in 2025 to 259.1 billion kilowatthours, but still remain 2.4 percent below the 10-year average.

The bill's supporters argue that adding or preserving 2.5 gigawatts of potential hydropower capacity could help the grid at a time when electricity demand is rising from data centers, manufacturing, electrification, and population growth. The bill would not guarantee those megawatts come online. It would keep eligible projects from being forced out solely because their construction commencement windows expired.

Hydropower also has limits that wind and solar developers do not face in the same way. Output depends on water flows, snowpack, precipitation, reservoir rules, and competing water needs. EIA said about half of U.S. hydropower generating capacity is in Washington, Oregon, and California, which makes western precipitation patterns important to national hydropower output.

What People Are Saying

"The Build More Hydro bill will help revive critical hydro projects across the nation and increase our domestic energy production, and I'm thrilled to see it headed to the President's desk. Energy security is national security, and this bill will help bolster our all-of-the-above energy portfolio while keeping costs low and the lights on for hardworking American families." - Sen. Steve Daines, R-Mont., in an April 21 statement.

"Our Nation desperately needs more energy, and I am delighted to see the House advance legislation to the President's desk that will build more hydroelectric dams. Once signed into law, this legislation will allow for the construction of nearly 40 projects totaling over 2.5 gigawatts of baseload power, improving grid reliability and lowering energy prices." - Rep. Dan Newhouse, R-Wash., in an April 21 statement.

"As we work to secure our grid and unleash American energy, hydropower can deliver affordable and reliable electricity to American families."

Rep. Brett Guthrie, R-Ky., chairman of the House Energy and Commerce Committee, in a committee statement.

"Hydropower remains one of the cornerstones of America's energy system, delivering reliable baseload power to roughly 30 million homes and businesses and providing nearly 40 percent of our black start capacity." - Rep. Bob Latta, R-Ohio, chairman of the Energy Subcommittee, in a committee statement.

The Big Picture

The next step is presidential action. If Trump signs S. 1020, the practical fight shifts from Congress to FERC, where licensees would have to request extensions and show good cause under the new authority.

The bill's political signal is already clear. At a time when Congress often splits sharply on energy policy, a hydropower deadline measure drew nearly unanimous Democratic support and overwhelming Republican support, while a small group of Republicans stood apart.

The implementation questions will be more technical than ideological. Watch which projects file for extensions, whether FERC grants the full additional time, and whether the claimed 2.5 gigawatts of potential capacity turns into steel, turbines, and power on the grid.
