On Monday, the Republican-led House Ways and Means Committee released the first draft of its rewrite of America’s clean energy tax credits.
The proposal might look, at first, like a cautious paring back of the tax credits. But the proposal amounts to a backdoor repeal of the policies, according to energy system and tax analysts.
“The bill is written to come across as reasonable, but the devil is in the details,” Robbie Orvis, a senior analyst at Energy Innovation, a nonpartisan energy and climate think tank, told me. “It may not be literally the worst text we envisioned seeing, but it’s probably close.”
The proposal would strangle new energy development so quickly that it could raise power costs by as much as 7% over the next decade, according to the Rhodium Group, an energy and policy analysis firm.
Senate Republicans have already indicated that the proposal is unworkable. But to understand why, it’s worth diving into the specific requirements that render the proposal so destructive.
The clean energy tax credits are one of the centerpieces of American energy policy. They’re meant to spur companies to deploy new forms of energy technology, such as nuclear fusion or advanced geothermal wells, and simultaneously to cut carbon pollution from the American power grid.
The U.S. government has long used the tax code to encourage the build-out of wind turbines or solar panels. But when Democrats passed the Inflation Reduction Act in 2022, they rewrote a pair of key tax credits so that any technology that generates clean electricity would receive financial support.
Under the law as enacted, these clean electricity tax credits provide 10 years of support to any electricity project — no matter how it generates power — for the foreseeable future. But the new Republican proposal would begin phasing down the value of the credit starting in 2029, and end the program entirely in 2032.
That might sound like a slow and even reasonable phase-out. But a series of smaller changes to the law’s text introduce significant uncertainty about which projects would continue to qualify for the tax credit in the interim. Taken together, these new requirements would kill most, if not all, of the tax credits’ value.
Here are three reasons why the Republican proposal would prove so devastating to the American clean electricity industry.
1. The new proposal introduces profound uncertainty about power plant financing for individual developers.
The new Ways and Means proposal begins to phase out the clean energy tax credits immediately. The proposal cuts the value of the tax credit by 20% per year starting in 2029, and ends the credit entirely in 2032.
But the GOP proposal changes a key phrase that helps financiers invest confidently in a given project.
Under the law as it stands today, developers can’t claim a tax credit until a project is “placed in service” — meaning that it is generating electricity and selling it to the grid. But a project qualifies for a tax credit in the year that construction on that project begins.
For example, imagine a utility that begins building a new geothermal power plant this year, but doesn’t finish construction and connect it to the grid until 2029. Under current law, that company could qualify for the value of the credit as it stands today, but it wouldn’t begin to get money back on its taxes until 2029.
But the GOP proposal would change this language. Under the House Republican text, projects only qualify for a tax credit when they are “placed in service,” regardless of when construction begins. This means that the new geothermal power plant in the earlier example could only get tax credits as set at the 2029 value — regardless of when construction begins.
What’s more, if work on the project were delayed, say by a natural disaster or unexpected equipment shortage, and the power plant’s completion date was pushed into the following year, then the project would only qualify for credits as set at the 2030 value.
In other words, companies and utilities would have no certainty about a tax credit’s value until a project is completed and placed in service. Any postponement or slowdown at any part of the process — even if for a reason totally outside of a developer’s control — could reduce a tax credit’s value.
This makes the tax credits far less dependable than they are today. Generally, companies have more ability to plan around when construction on a power plant begins than they do over when it is placed in service.
This change will significantly raise financing costs for new energy projects of all types because it means that companies won’t be able to finalize their capital stack until a project is completed and turned on. The most complicated and adventurous projects — such as new geothermal, nuclear, or fusion power plants — could face the highest cost inflation.
2. The proposal imposes unworkably strict rules on the parts, components, and minerals used in clean energy projects.
The Inflation Reduction Act as it stands today attaches a “foreign entity of concern” rule to its $7,500 tax credit for electric vehicle buyers.
In order to qualify for that EV tax credit, automakers had to cut the percentage of Chinese-processed minerals and battery components that appear in their electric models every year. This phased in gradually over time — the idea being that while China dominates the EV and battery supply chain today, the requirement would provide a consistent spur to reshore production.
Somewhat ironically, the GOP proposal ditches the EV tax credit and its accompanying foreign sourcing rules. But it applies a strict version of the foreign entity of concern rule to every other tax credit in the law, including the clean electricity tax credits.
Under the House proposal, no project can qualify for the tax credits unless it receives no “material support” from a Chinese-linked entity. The language defines “material support” aggressively and expansively — it means any “any component, subcomponent, or applicable critical mineral” that is “extracted, processed, recycled, manufactured, or assembled.”
This provision, in other words, would essentially disqualify the use of any Chinese-made part, subcomponent, or metal in the construction of a clean electricity project, although the rule includes a partial and narrow carve-out for some components that are bought from a third-party. Even a mistakenly Chinese-sourced bolt could result in a project losing millions of dollars of tax credits.
Technically, the law also disqualifies the use of goods from other “foreign entities of concern” as defined under U.S. law, which include Russia, Iran, and North Korea. But China is the United States’ third largest trading partner, and it is the only manufacturer of the type of goods that matter to the law.
Solar projects would face immediate challenges under the new rule. China and its domestic companies command more than 80% of the market share for all stages of the solar panel manufacturing process, according to the International Energy Agency.
But then again, the proposal would be an issue for virtually all energy projects. Copper wiring, steel frames, grams of key metals — even geothermal plants rely on individual Chinese-made industrial components, according to Seaver Wang, an analyst at the Breakthrough Institute. These parts also intermingle on the global market, meaning that companies can’t be certain where a given part was made or where it comes from.
These new and stricter rules would kick in two years after the reconciliation bill passes, which likely means 2027.
This provision by itself would be unworkable. But it is made even worse by being coupled to the tax credit’s change to a “placed in service” standard. That’s because projects that are already under construction today might not meet these new foreign entity rules, essentially stripping them of tax credits that companies had already been banking on.
These projects have assumed that they will qualify for the tax credits’ full value, no matter when their power plant is completed, because they have already begun construction. But the GOP proposal would change this retroactively, possibly threatening the financial viability of energy projects that grid managers have been assuming will come online in the next few years.
In some ways, these two changes taken together are “worse than repeal,” Mike O’Boyle, an Energy Innovation analyst, told me. “A number of projects under construction now will lose eligibility."
It is also made worse by the House GOP plan to phase out the tax credits. If companies could plan on the tax credits remaining on the books long-term then the foreign entity rules might spur the creation of a larger domestic — or at least non-Chinese — supply chain for some clean energy inputs. But because the credits will phase out by 2032 regardless, fewer projects will qualify, and it won’t be worth it for companies to invest in alternative supply chains.
3. The GOP proposal would end developers’ ability to transfer their tax credits to other firms.
Finally, the House Republican proposal would end companies’ ability to sell the value of tax credits to other firms. The IRA had made it easier for utilities and developers to transfer the value of tax credits to other companies — essentially allowing companies with a lot of tax liability, such as banks, to acquire the rights to renewable developers’ credits.
The GOP proposal ends that right for every tax credit, even those that Republicans have historically looked on more favorably, such as the tax credit that rewards companies for capturing carbon dioxide from the atmosphere.
This change — coupled with the foreign entity and placed-in-service rules — will have an impact today on power markets by further gumming up the pipeline of new energy projects planned across the country, according to Advait Arun, an analyst at the Center for Public Enterprise.
The end to transferability “functionally imposes higher marginal tax rates on all of these projects,” Arun told me. “The prices that developers will get for their tax credits on the tax equity market today will be a lot lower than normal.”
That could significantly raise the cost of any new energy projects that get planned. And that will lead in the medium term to a further slowdown in the growth of electricity supply, just as turbine shortages have made it more difficult than ever to build a new natural gas power plant.
While many of these changes may seem academic, they will hit energy consumers faster than legislators might realize. Natural gas prices in the U.S. have been unusually high in 2025. A slowdown in the growth of non-fossil energy will further stress natural gas supplies, raising power prices.
Taken together, Orvis told me, these changes to the IRA “will increase the price of the vast majority of new capacity coming online next year,” Orvis said. “It’s an immediate price hike for new energy, and you can’t replace that with new gas.”
