How much battery energy storage is currently available

Generators added 10.4 GW of new battery storage capacity in 2024, the second-largest generating capacity addition after solar. Even though battery storage capacity is growing fast, in 2024 it was only 2% of the 1,230 GW of utility-scale electricity generating capacity in the United States. [pdf]

FAQS about How much battery energy storage is currently available

How much power does battery storage have in the US?

The cumulative output and capacity of battery storage installed in the US have reached 17,027MW and 45,588MWh, respectively. That meant an 86% increase in cumulative installed capacity in megawatts (power) and an increase of 83% in cumulative installed capacity in megawatt-hours (energy).

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.

Why is battery energy storage important in 2022?

As the world transitions to greener sources of power generation such as solar PV and wind, battery energy storage developments will be critical in meeting future energy demand. Global BESS capacity additions expanded 60% in 2022 over the previous year, with total new installations exceeding 43 GWh.

How many GW of battery capacity are there in the US?

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. 94% of capacity installed in US ISOs today is within either CAISO or ERCOT.

Will 140 GW of battery energy storage be possible?

And if demand grows as projected, while the cost of building battery energy storage projects continues to decline, 140 GW by the end of this decade may be more feasible than it appears at first glance. Battery energy storage systems have become the fastest-growing grid-scale energy technology in America, alongside solar generation.

How much does a battery energy storage system cost?

In 2015, the levelised cost of such a battery energy storage system (BESS) would have been between US$347 and US$739/MWh, albeit not many systems of that duration were being installed in the US nine years ago. The average levelised cost of a solar-plus-storage installation was US$81/MWh to US$153/MWh.
