Battery storage capacity in North America

How much battery storage is there in the United States?

Mitsubishi Power claimed the battery storage capacity across the United States is just 2GWh via lithium-ion batteries although that is clearly an outdated or inaccurate figure, with recent figures from the Energy Information Administration saying there was 4.6GW of battery storage online as of the end of 2021.

Is battery storage capacity growing in the United States?

Growth in U.S. battery storage capacity is outpacing the early growth of utility-scale solar capacity, which began expanding in 2010 and rose from less than 1 GW in 2010 to 13.7 GW in 2015, the agency said. Developers and power plant operators expect to be using 1.4 GW more battery capacity by the end of the year than in October.

What are the largest battery storage sites in the United States?

The two largest operating utility-scale battery storage sites in the United States as of March 2019 provide 40 MW of power capacity each: the Golden Valley Electric Association’s battery energy storage system in Alaska and the Vista Energy storage system in California.

Which states have the most battery storage capacity?

As of December 2020, California (506 MW) and four other states account for over 70% of the US's battery storage power capacity. Much of the recent increase in new storage capacity comes from battery energy systems co-located with or connected to solar projects.
