According to the EIA, utility-scale battery storage capacity in the U.S. exceeded 26 gigawatts (GW) in 2024, with 10.4 GW added last year alone. Despite this growth, battery storage still accounts for just 2% of the country’s total 1,230 GW of utility-scale electricity capacity. Looking ahead, 2025 is expected to see even faster growth, with 19.6 GW of new battery storage capacity planned.
This surge is driven by significant cost reductions—batteries are now two to three times cheaper than before—and by their ability to capitalize on daily price fluctuations. Battery systems can store electricity during off-peak hours when prices are low and discharge it during peak hours when prices are high, effectively performing a form of daily risk arbitrage.
