Senate GOP bill spares nuclear and geothermal energy while hammering wind and solar

In a significant move following the passage of a similar bill in the House, Senate Republicans unveiled their version of the budget reconciliation bill on Monday night. This new proposal by the Senate Finance Committee aims to drastically alter key aspects of the renewable-energy-friendly Inflation Reduction Act (IRA), while selectively preserving certain energy sources. Wind, solar, and hydrogen technologies face severe cuts under the latest bill, while geothermal, nuclear, hydropower, and long-duration energy storage are largely unaffected. In a swift action, the Senate GOP plans to eliminate residential solar tax credits, giving consumers merely 180 days post-signing to claim these benefits. Additionally, solar leasing companies will lose eligibility for these credits, which could significantly impact the residential solar market. Commercial incentives for wind and solar projects will see a more lenient timeline compared to the IRA, which offered support through 2032. Under the new proposal, projects starting within the first six months after the bill’s signing will access the full credit. However, those beginning construction in 2026 and 2027 will only receive 60% and 20% of the credit, respectively, with the support disappearing altogether thereafter. Hydrogen tax credits are also set to conclude this year, aligning with the House version of the bill, adding further challenges for hydrogen startups that have faced fluctuating policies over recent years. Interestingly, while carbon capture initiatives were initially at risk, the Senate's proposal modifies existing provisions by eliminating distinctions in the 45Q tax credit, allowing all carbon capture projects to qualify for the same incentives. Nuclear, geothermal, and hydropower technologies benefit from a slight extension of the tax credit phase-out period. Projects beginning construction in 2033 will receive the full credit, a year longer than what the IRA stipulates. The phase-out will continue with the credit decreasing to 75% in 2034 and 50% in 2035 before ending in 2036. This legislative approach aligns with GOP priorities to diminish support for wind and solar energy while protecting nuclear and geothermal options. The inclusion of long-duration energy storage is a noteworthy surprise, as it could enhance the viability of wind and solar by providing more reliable energy sources around the clock. However, this bill still faces hurdles; it must pass through the Senate parliamentarian before heading to the House, which has set a deadline of July 4 to finalize the package.
