US deployed 11.9GW of BESS in 2024, 18.2GW of grid-scale additions expected in 2025

AI generated summary

The United States achieved a record deployment of 11.9GW of battery energy storage systems (BESS) in 2024, marking a 55% increase from the previous year. This growth is part of a broader trend in renewable energy, with the country adding 49GW of solar capacity and over 50GW of total renewable energy capacity, including 5GW from wind. California and Texas were the primary contributors, accounting for 84% of the new BESS capacity, with significant projects like the Gemini solar-plus-storage project in Nevada leading the way.

Looking ahead, the Energy Information Administration (EIA) forecasts an additional 18.2GW of utility-scale BESS capacity for 2025, alongside 32.5GW from utility-scale solar PV. This growth is essential for balancing supply and demand in the energy grid and enhancing stability. The EIA's projections indicate that solar and battery storage will together contribute to over 50GW of the total 63GW of new utility-scale electricity-generating projects expected in 2025, underscoring the increasing importance of energy storage in the transition to renewable energy.
