Us power supply administration energy storage

What is an energy storage system?

An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.

How much energy storage does the US have?

To put that in perspective, that’s more than eight times our current storage capacity — a game-changer for how we generate and use electricity. Right now, the US has about 83 GWh of energy storage, with nearly 500,000 battery installations helping to keep the grid running smoothly.

What is the power capacity of a battery energy storage system?

As of the end of 2022, the total nameplate power capacity of operational utility-scale battery energy storage systems (BESSs) in the United States was 8,842 MW and the total energy capacity was 11,105 MWh. Most of the BESS power capacity that was operational in 2022 was installed after 2014, and about 4,807 MW was installed in 2022 alone.

How much energy is stored in a battery?

Globally, over 30 gigawatt-hours (GWh) of storage is provided by battery technologies (BloombergNEF, 2020) and 160 gigawatts (GW) of long-duration energy storage (LDES) is provided by technologies such as pumped storage hydropower (PSH) (DOE 2020).

Can the US lead the way in energy storage innovation?

With the right policies and investments, SEIA believes the US can lead the way in energy storage innovation, making our power supply more stable and sustainable for generations to come. And as part of this advocacy work, the organization also recently launched a new guide to energy storage policies at the state level for the entire US.

What energy sources will the US battery capacity exceed by 2024?

Developers currently plan to expand U.S. battery capacity to more than 30 gigawatts (GW) by the end of 2024, a capacity that would exceed those of petroleum liquids, geothermal, wood and wood waste, or landfill gas. Two states with rapidly growing wind and solar generating fleets account for the bulk of the capacity additions.
