Overview

• From January through July 2025, solar and wind supplied about 90% of new U.S. utility‑scale generating capacity, with solar alone contributing 16.05 GW, or roughly 74.4%.
• In July 2025, developers brought 46 utility‑scale solar units totaling 1,181 MW online, marking the 23rd consecutive month that solar led all new capacity additions.
• Utility‑scale solar capacity expanded from 91.82 GW in September 2023 to 153.09 GW by July 2025, while wind grew by 10.68 GW and natural gas by 3.74 GW over the same period.
• Solar’s utility‑scale share of installed capacity stands at 11.42% versus wind’s 11.81%, with all renewables at about 32.22%; including small‑scale solar lifts renewables above one‑third of total U.S. capacity.
• FERC’s three‑year outlook flags 92.631 GW of high‑probability solar additions and 22.528 GW of wind through July 2028, which, if realized, could make utility‑scale solar the No. 2 U.S. capacity source by mid‑2028.
