The American Clean Power Association has released its fourth quarter 2025 Clean Power Quarterly Market Report, showing that the USA clean energy sector recorded its strongest year to date. Developers commissioned 18.6 GW of new utility-scale solar, wind and energy storage capacity during the fourth quarter, bringing total additions in 2025 to more than 50 GW.
These three technologies accounted for 90.5% of all new power capacity installed in 2025 and more than 80% of total capacity additions over the past five years, according to data from the American Clean Power Association and the U.S. Energy Information Administration. Battery storage recorded the largest growth, with deployments increasing by nearly 4 GW compared with 2024, representing a year-on-year rise of 41%.
The near-term development pipeline increased to more than 187.5 GW, although growth slowed during the fourth quarter with only 2 GW added.
Power purchase agreement activity declined by 27% compared with the previous year, indicating a potential slowdown in clean power deployment between 2028 and 2030. During the second half of 2025, many electricity buyers postponed procurement decisions while awaiting greater clarity on federal policy and tax credit eligibility.
No new offshore wind capacity was commissioned in the fourth quarter, and the offshore wind development pipeline decreased following several project cancellations.
