Enabling power grids to function more flexibly and resiliently, the deployment of battery storage across the US has increased from about 100MW at the end of 2012 to 1,650MW by the end of 2020, accelerating from an inflection point year in 2015. A new report from the US Department of Energy’s Energy Information Administration (EIA) takes a deep dive into the numbers.
Planning data collected from project developers by December 2020 showed that with 10GW set to go online by 2023, the installed base would have increased more than 1,000% from 1GW of operational capacity in 2019. California leads among states, and will host about 40% of that new capacity. This is likely due to the AB2514 mandate, which ordered California investor-owned utilities (IOUs) to install 1,325MW of storage by 2024.
