A little-noticed provision in the Senate tax bill will sabotage the efforts of tribes, rural electric cooperatives, and public power authorities to develop local affordable energy projects by striking a section of the Inflation Reduction Act that enabled tax-exempt groups to claim the clean energy tax credits as direct cash payments from the Treasury.
The IRA included strict domestic sourcing requirements beginning in 2026 for groups utilizing this “direct pay” option on projects larger than 1 megawatt. But the law also created exceptions for cases where domestic components were not available in sufficient quantity or quality, or would increase costs by more than 25%. The Senate bill would get rid of these exceptions.
“It just makes it unlikely for those projects to go forward — or more likely for those projects to go forward with a private developer, instead of with a public utility or a tribe or a rural co-op,” Grace Henley, a tax attorney with the Natural Resources Defense Council, told me. “And so they don’t really do anything to increase the amount of domestic material that would be used, they just hurt the projects that are seeking to invest in clean energy infrastructure for these communities to lower costs.”
Public power and tribal energy advocates warn that without the exceptions, energy development will become impossible for their constituents.
Wind and solar projects being developed by these groups are already threatened by the bill’s rapid phase-out of wind and solar tax credits and its complex rules related to using materials from China. Chèri Smith, the executive director of the Alliance for Tribal Energy, told me that Tribes face longer development timelines than the average private developer. “We have multiple stages of approval that are unique to tribal energy development,” she told me, including lengthy internal consultation processes. The changes to direct pay will put these projects further out of reach, she said.
The Alliance provides free energy development consulting services to more than 100 Tribes. Smith sent me a list of projects in Alaska Native villages, Arizona, California, and Oregon that could be killed by the tax credit changes. “Alaska Native villages face some of the highest energy costs in the country,” she said, largely due to their reliance on diesel generators. Just over a third of the Hopi Tribe in Arizona lacks access to electricity, but now multiple microgrid projects meant to close the gap are at risk. Many of the projects on the list are also doubly threatened by grant cancellations and the repeal of the Tribal Energy Loan Guarantee Program.
“The bill is particularly harmful to Tribal Nations, pulling the rug out from under projects that would strengthen their energy sovereignty and power local communities,” Democratic Senators Martin Heinrich, Ron Wyden, and Brian Schatz wrote in a joint statement on Thursday. “Together, the Tribal Energy Loan Guarantee Program and our Inflation Reduction Act’s clean energy tax credits have cleared pathways and removed significant barriers for Tribes to finance and build their own resilient energy infrastructure.”
The American Public Power Association is also sounding the alarm. John Godfrey, the group’s senior government relations director, told me that in addition to wind and solar, municipal utilities and rural electric co-ops are also considering nuclear and hydropower projects. For example, Energy Northwest, a consortium of 29 public utilities in Washington State, has plans to retrofit the Columbia Generating Station nuclear plant to increase its power output. It’s also in early stages to deploy four small, modular nuclear reactors. As my colleague Matthew Zeitlin wrote a few days ago, the governor of New York has also tasked the New York Power Authority with developing a new nuclear plant in the state.
Nuclear and hydropower “are technologies where often there is not a U.S. source, but there is a good trading partner source — Canada, Germany, Japan,” Godfrey said. By tightening the domestic sourcing requirements for direct pay, the bill would “hinder the very technologies that there’s generally a bipartisan consensus we need to be developing.”
Public utilities and electric co-ops, which serve close to 30% of electric customers in the U.S., are also unfairly singled out by the provision, he said. “If my public power utility wants to develop a project and they need a Canadian turbine, they can’t get any credit. But if a taxable corporation down the street develops exactly the same project, they can.”
“If the purpose is to encourage hydropower, that’s not a good use of resources,” he said.
