U.S. to Add 63 GW of Utility-Scale Power in 2025, Led by Solar and Storage

The United States is projected to install 63 GW of new utility-scale power capacity in 2025, marking a 30% increase from 48.6 GW in 2024, according to the U.S. Energy Information Administration (EIA). This will be the largest annual capacity addition since 2002.

Key Trends in 2025 Capacity Additions

• Solar and battery storage will account for 81% of the new capacity.
• Solar alone will contribute 32.5 GW, over 50% of total growth.
• Wind additions are expected to reach 7.7 GW, recovering from 5.1 GW in 2024.
• Battery energy storage will see a record 18.2 GWh increase, a 77% growth from 2024.

Solar Expansion

• The U.S. added 30 GW of utility-scale solar in 2024, comprising 61% of total new capacity.
• In 2025, 32.5 GW of solar capacity is expected.
• Texas (11.6 GW) and California (2.9 GW) will lead solar additions, contributing nearly 50%.
• Other major solar states: Indiana, Arizona, Michigan, Florida, and New York (adding 7.8 GW combined).
• Community solar grew 35% YoY, adding 1.7 GW in 2024, according to Wood Mackenzie & Coalition for Community Solar Access.

Wind Energy Outlook

• 5.1 GW of wind capacity was added in 2024, the lowest since 2014.
• 7.7 GW of wind projects are expected in 2025, with Texas, Wyoming, and Massachusetts leading.
• Major offshore wind projects coming online in 2025:
  • Vineyard Wind 1 (800 MW, Massachusetts)
  • Revolution Wind (715 MW, Rhode Island)

Battery Energy Storage Surge

• Utility-scale BESS capacity to reach 18.2 GWh in 2025, a 77% increase from 10.3 GWh in 2024.
• EIA had initially forecasted 14.3 GWh BESS in 2024, representing 23% of new capacity additions.

The rapid solar and storage expansion highlights the U.S.’s continued shift towards renewable energy, while offshore wind gains traction despite slower onshore wind growth.
