Key highlights of the report “Clean Power Quarterly Market Report | Q4 2025” published by American Clean Power Association are:
• Developers commissioned 18,648 MW of new utility-scale solar, wind, and storage capacity in Q4 2025, down 3% from the same quarter in 2024.
• Total 2025 clean power capacity additions totaled 50,344 MW, accounting for over 90% of new capacity and bringing total operational clean power to 363,301 MW.
• The battery storage industry saw its best year yet for deployments after adding 16,175 MW/46,520 MWh of new capacity in 2025, surpassing the previous annual deployment record set in 2024 by 41%.
• The clean power pipeline rose to 187,514 MW in Q4, up just 1% from Q3, and up 8% year-over-year.
• The second and third quarters of 2025 also saw pipeline growth of 1% or less, down from averaging 5% quarterly growth over 2021-2024.
• Clean power offtake announcements dropped 36% year-over-year, as policy uncertainty and fluctuating tariffs made future project costs more difficult to predict and contract negotiations more complex.
• Power purchase agreement announcements saw the steepest drop by volume, falling from 45.4 GW in 2024 to 33 GW in 2025. Utilities and C&I buyers alike saw lower announced offtake volumes, down 26% and 36%, respectively.
• The drop in offtake in 2025 could be an early warning sign of lower deployments towards the end of the decade, just as a supportive policy and market environment in the early 2020s put 2024 and 2025 on track to be strong deployment years.
