Current state of energy storage costs in the united states

What is the cost of battery storage?

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). Battery storage costs fell by 72% between 2015 and 2019, a 27% per year rate of decline.

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

Most large-scale battery energy storage systems are expected to come online in the United States over the next three years. These systems will be built at power plants that also produce electricity from solar photovoltaics.

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!

Can energy storage systems generate revenue?

Energy storage systems can generate revenue through both discharging and charging of electricity. However, our current data do not distinguish between battery charging that generates system value or revenue and energy consumption that is simply part of the cost of operating the battery.

What was the rate of decline in battery storage costs?

Battery storage costs fell by 27% per year between 2015 and 2019, with average battery energy storage capital costs in 2019 being $589 per kilowatthour (kWh).

How much energy does a battery storage system use?

The average energy capacity of long-duration battery storage systems was 21.2 MWh. This is between three and five times more than the average energy capacity of short- and medium-duration battery storage systems.
