Clean Power Quarterly Market Report | Q1 2025

ACP’s Q1 2025 report finds clean energy achieved its second-strongest first quarter on record, with 7.4 GW of new capacity representing $10 billion in domestic investment.

American clean power capacity now exceeds 320 GW nationwide—enough to power nearly 80 million homes—driven by record-breaking battery storage deployment and a robust development pipeline worth $328 billion. The first quarter’s 115 project phases demonstrate continued private sector confidence in domestic energy production, with eight of the top ten deployment states having voted Republican in 2024. Battery storage surpassed 30 GW total capacity with a 65% year-over-year increase, while the development pipeline grew 12% to reach 184 GW, signaling sustained job creation and investment across America.

Report Highlights

• Total Installed Capacity: U.S. clean power capacity reached 320+ GW in Q1 2025, enough to power nearly 80 million American homes.
• Strong Q1 Installations: 7.4 GW of new capacity came online, making it the second-strongest Q1 on record. The 115 project phases that came online in Q1 total $10 billion of private investment into the U.S. economy.
• Record-Breaking Storage Growth: Battery storage capacity surpassed 30 GW nationwide, representing a 65% increase year-over-year, with Q1 2025 setting a new first-quarter record at 1,602 MW.
• Robust Project Pipeline: The development pipeline grew 12% year-over-year to reach 184,418 MW, with storage and wind pipelines growing 57% and 24% respectively. This represents $328 billion in project investment if everything in the pipeline is built. (Projects under construction or in advance stages of development (pipeline) are typically fully permitted projects. The growth of the pipeline does not signal any advances in the volume of projects receiving permits.)   
• Technology Mix: Q1 additions included 4,459 MW of utility-scale solar, 1,602 MW of storage, and 1,327 MW of land-based wind.
• Leading States:
  • Eight of the top ten states for Q1 clean power additions voted Republican in the 2024 presidential election.
  • Texas leads the nation in clean power, with a portfolio reaching 80+ GW—a 20% increase from Q1 2024—and ranks first in utility-scale solar (28 GW) and land-based wind (43 GW) capacity.
  • Indiana quadrupled its energy storage capacity in just one quarter, while adding 435 MW of new solar capacity.
