Nearly 500 MW of large batteries installed on the US grid in three years (w/ chart)


While defenders of old and uncompetitive forms of energy decry the small capacity of battery storage that has been installed to date, the latest data from the U.S. Department of Energy’s Energy Information Administration (EIA) shows that battery deployment is gaining speed.

Specifically, this week EIA revealed that nearly 500 MW of large batteries have been deployed on the U.S. grid over the last three years, marking a big jump from previous years and representing the majority of installed capacity in the 21st century. EIA’s data does not include behind-the-meter batteries installed by residential customers or businesses.
