How much does battery storage cost?

The costs of installing and operating large-scale battery storage systems in the United States have declined in recent years. Average battery energy storage capital costs in 2019 were $589 per kilowatthour (kWh), and battery storage costs fell by 72% between 2015 and 2019, a 27% per year rate of decline.

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.

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.

When will large-scale battery energy storage systems come online?

Most large-scale battery energy storage systems we expect to come online in the United States over the next three years are to be built at power plants that also produce electricity from solar photovoltaics, a change in trend from recent years.

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.
