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.

How many battery energy storage systems are there?

Within the interconnection queues of American ISOs, there are around 570 GW of battery energy storage systems. All of this capacity has a projected date of commercial operations by the early 2030s. In fact, much of this capacity has projected operational dates in the next twelve months - according to the queue data.

Are battery energy storage systems the fastest growing grid-scale energy technology?

Battery energy storage systems have become the fastest-growing grid-scale energy technology in America, alongside solar generation. Currently, there is around 17 GW of commercially operational battery capacity by rated power across all Independent System Operators in the US. This has grown rapidly from around 1 GW just four years ago.

Are batteries a key component of battery energy storage systems?

Batteries form a major key component of battery energy storage systems. Large-scale renewable energy installation in the U.S. economy will lead to enhanced deployment of battery energy storage systems in order to prevent intermittent power supply from renewable sources.

Are battery energy storage projects commercially operational?

In fact, in ERCOT, battery energy storage projects with signed Interconnection Agreements have become commercially operational at a 100% rate. So, let’s assume projects will continue to become commercially operational at a similar rate. This results in a projected total battery energy storage buildout of just under 150 GW by the end of 2030.

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.
