Overview

• Senate Republicans’ updated One Big Beautiful Bill matches the House’s three-year phase-out timeline for wind and solar tax credits.
• The revised text imposes strict in-service deadlines requiring projects to begin operations by specified dates to qualify for remaining incentives.
• Carve-outs for hydrogen and nuclear credits were secured to preserve support for emerging clean energy technologies.
• President Trump’s denouncement of green subsidies as a “giant scam” has driven the push toward steeper, more rapid rollbacks.
• Lawmakers will now reconcile the Senate and House texts to finalize the clean energy rollback before the bill’s final passage.
