Oregon Scrambles to Save Green Projects as Trump’s Tax Credit Axe Falls

Oregon Scrambles to Save Green Projects as Trump’s Tax Credit Axe Falls

Oregon Gov. Tina Kotek ordered state agencies to fast-track permits for wind and solar projects so they can start construction by July 4, 2026, ahead of expiring federal tax credits. The Trump-backed “One Big Beautiful Bill Act” accelerates the phaseout of these incentives, putting at least 9–11 major Oregon projects at risk. Oregon could lose about 4 gigawatts of planned renewables if deadlines are missed.
