In just one year — from 2020 to 2021 — utility-scale battery storage capacity in the United States tripled, jumping from 1.4 to 4.6 gigawatts (GW), according to the US Energy Information Administration (EIA). Small-scale battery storage has experienced major growth, too. From 2018 to 2019, US capacity increased from 234 to 402 megawatts (MW), mostly in California.
While this progress is impressive, it is just the beginning. The clean energy industry is continuing to deploy significant amounts of storage to deliver a low-carbon future.
Having enough energy storage in the right places will support the massive amount of renewables needed to add to the grid in the coming decades. It could look like large-scale storage projects using batteries or compressed air in underground salt caverns, smaller-scale projects in warehouses and commercial buildings, or batteries at home and in…
