Report from the American Clean Power Association finds told clean power capacity in the U.S. hit 370 GW in Q1, enough to power 80 million homes, while the pipeline for new projects grew 6% over the previous year.
A new report from the American Clean Power Association (ACP) shows that U.S. developers brought a total of 6.4 gigawatts (GW) of new utility-scale solar, wind, and energy storage capacity online in Q1 2026 — bringing total domestic clean power capacity to over 370 GW.
According to the Q1 2026 Clean Power Quarterly Market Report, capacity additions in the first three months of 2026 represented 3.625 GW of utility-scale solar, 2.382 GW of energy storage and 415 MW of wind. The additions meant the capacity of utility-scale solar has now exceeded that of wind as the largest source of clean power generation capacity in the country.
The state of Texas now accounts for over one quarter of all installed clean energy capacity at 96.4 GW, placing it on the verge of becoming the first state to install 100 GW. California comes in second, with nearly 46.4 GW, with Oklahoma in third place at just over 15 GW.
Despite clean energy reaching ever higher heights, the report revealed that capacity additions were down by 17% compared to the nearly 7.7 GW energized in the Q1 of 2025. That decrease can be explained by the 6.4 GW of clean power capacity originally expected to be operational by the end of Q1, which is now delayed.
