Reducing end-user demand and demand charges —Commercial and industrial electricity consumers can deploy on-site energy storage to reduce their electricity demand and associated demand charges, which are generally based on their highest observed levels of electricity consumption during peak demand periods.
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.
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.
In general, pumped-hydro, compressed-air, and large energy-capacity battery ESSs can supply a consistent level of electricity over extended periods of time (several hours or more) and are used primarily for moderating the extremes of daily and seasonal variations in electricity demand.
While we''re geeking out, did you know the latest cabinets use self-healing electrolytes? It''s like Wolverine for batteries – minor scratches disappear before you can say “fast charging stability.”

ESSs use more electricity for charging than they can provide when discharging and supplying electricity. Because of this difference, EIA publishes data on both gross generation and net generation by ESSs.

Charging efficiency refers to how effectively energy is stored within the cabinet, while discharging efficiency indicates how well that stored energy can be retrieved.
