How big is energy storage in the US?

In the U.S., electricity capacity from diurnal storage is expected to grow nearly 25-fold in the next three decades, to reach some 164 gigawatts by 2050. Pumped storage and batteries are the main storage technologies in use in the country. Discover all statistics and data on Energy storage in the U.S. now on statista.com!

What is the largest energy storage resource in 2021?

That’s up from a previous record build of 3.7 GW in 2021. At 67%, pumped storage is the largest energy storage resource, with battery and thermal storage accounting for the remainder. Due mainly to growing deployment of large-scale lithium-ion batteries on the grid, pumped hydro’s share of U.S. energy storage dropped from 78% in 2021.

Which states have the most battery storage capacity?

Two states with rapidly growing wind and solar generating fleets account for the bulk of the capacity additions. California has the most installed battery storage capacity of any state, with 7.3 GW, followed by Texas with 3.2 GW.

How many large-scale battery storage systems are there in the United States?

At the end of 2019, 163 large-scale battery storage systems were operating in the United States, a 28% increase from 2018.

What is the largest battery capacity addition in the United States?

Before last year, the largest annual battery power capacity addition in the United States occurred in 2018, when a record 222 MW of large-scale battery storage was added. In 2019, 152 MW of battery power capacity was installed, 32% less than in 2018.

Which states have the most small-scale battery storage power capacity?

In 2019, 402 MW of small-scale total battery storage power capacity existed in the United States. California accounts for 83% of all small-scale battery storage power capacity. The states with the most small-scale power capacity outside of California include Hawaii, Vermont, and Texas.
