U.S. tax credit phaseout raises renewable power contract prices

4 min read

The accelerated phaseout of 20-year-old renewable tax credits under the 2025 tax law has driven developers to "safe harbor" projects ahead of a July 4 deadline, creating a pipeline of more than 200 gigawatts of solar capacity, Wood Mackenzie says. Analysts at LevelTen Energy warn contract prices for wind and solar could rise 40–50%, with some early Texas deals up 120%. The credits covered at least 30% of project costs, so their loss risks higher electricity prices even as demand from AI and other sources grows; some firms say unsubsidized projects remain competitive due to elevated power prices.
