Batteries are a fast-growing secondary electricity source for the grid

eia | Source: EIA | Posted 09/06/2024

Utility-scale battery energy storage systems have been growing quickly as a source of electric power capacity in the United States in recent years. In the first seven months of 2024, operators added 5 gigawatts (GW) of capacity to the U.S. electric power grid, according to data in our July 2024 electric generator inventory. In 2010, only 4 megawatts (MW) of utility-scale battery energy storage was added in the United States. In July 2024, more than 20.7 GW of battery energy storage capacity was available in the United States.

Utility-scale battery energy storage systems have rapidly expanded as an electric power capacity source in the U.S., with operators adding 5 gigawatts (GW) in the first seven months of 2024. Just a decade earlier in 2010, only 4 megawatts (MW) were added. By July 2024, the U.S. had over 20.7 GW of battery energy storage capacity available, data from the July 2024 electric generator inventory reveals.

Battery energy storage systems are crucial for supporting electric power grids, offering services like balancing supply and demand, conducting arbitrage to move electricity from low-price to high-price periods, and storing excess energy from renewable sources like wind and solar. These systems do not generate electricity but store electricity that has already been produced, making them secondary sources of electricity, and are integral in ensuring grid stability and efficiency.
