Solar and battery storage to make up 81% of new U.S. electric-generating capacity in 2024

Developers and power plant owners plan to add 62.8 gigawatts (GW) of new utility-scale electric-generating capacity in 2024, according to our latest Preliminary Monthly Electric Generator Inventory. This addition would be 55% more added capacity than the 40.4 GW added in 2023 (the most since 2003) and points to a continued rise in industry activity. We expect solar to account for the largest share of new capacity in 2024, at 58%, followed by battery storage, at 23%.
