Utility-scale battery storage capacity in the United States has expanded substantially, posting an annual average growth rate of 70% throughout the prior three-year period. As of the close of 2025, operational battery storage capacity across the nation totaled 43.6 gigawatts, with an additional 8.3 gigawatts brought online during the first half of 2026, bringing total nameplate capacity to approximately 52 GW.
Projected expansion plans indicate that operators intend to deploy 54 additional gigawatts of battery storage capacity over the subsequent two and a half years. Installation schedules show 14 GW planned for later this year, 26 GW scheduled for 2027, and 14 GW targeted for 2028.
Solar photovoltaic installations represent the primary category of facilities coupling with battery storage. The Bellefield Solar and Energy Storage Farm in California, which commenced operations in December 2025, initially combines 500 megawatts of photovoltaic capacity with 500 megawatts of battery storage. Expansion plans for this facility aim to double both its solar and storage components, with the additional capacity anticipated to be operational by November. Upon completion, Bellefield would represent the largest battery storage facility nationwide. The Manatee Solar Energy Center in Florida, operational since 2021, operates with 75 megawatts of solar capacity paired with 409 megawatts of storage and currently ranks as the second-largest battery storage installation. The Gemini Solar Hybrid facility in Nevada houses 690 megawatts of photovoltaic capacity alongside 380 megawatts of storage, having begun operations in 2024.
The integration of battery storage with solar facilities permits operators to store electricity during periods of depressed wholesale pricing and release stored power during peak pricing intervals, creating opportunities for increased revenue generation.
