EIA: U.S. battery storage capacity expected to double by 2023

April 18,2023


The installed capacity of large-scale battery storage systems in the United States is expected to double by 2023, according to the U.S. Energy Information Administration (EIA).

Among its findings, solar PV will account for more than half (54%) of all new generation generation by 2023, out of a total of 54.5GW. This follows a tough year in 2022, with utility-scale new solar installations down 23% year-over-year due to factors such as supply chain disruptions.

Developers could add 29.1GW of new solar PV this year if most or all of the delayed projects are completed in 2022. The strongest year for solar generation is 2021, with 13.4GW added.

Meanwhile, operating asset capacity for battery storage is around 8.8GW, with a further 9.4GW expected to be added by 2023.

California and Texas are the two states with the highest solar PV capacity this year, as well as the two states with the most new battery capacity.

Battery energy storage accounts for 17% of the new generating units planned for the U.S. grid in 2023, and solar photovoltaics account for 54%. In December, EIA data specialist Suparna Ray wrote that battery storage capacity had grown “significantly” even faster than solar, noting that U.S. PV capacity rose from less than 1GW in 2010 to 13.7GW in 2015.
