A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
Battery storage capacity in the power sector is expanding rapidly. Over 40 gigawatt (GW) was added in 2023, double the previous year’s increase, split between utility-scale projects (65%) and behind-the-meter systems (35%).
Battery storage has many uses in power systems: it provides short-term energy shifting, delivers ancillary services, alleviates grid congestion and provides a means to expand access to electricity. Governments are boosting policy support for battery storage with more targets, financial subsidies and reforms to improve market access.
The state of charge influences a battery’s ability to provide energy or ancillary services to the grid at any given time. Round-trip eficiency, measured as a percentage, is a ratio of the energy charged to the battery to the energy discharged from the battery.
For context, the largest capacity of a GivEnergy battery storage container is 500 kilowatts (kW). That’s roughly 196 times smaller than the Pillswood battery storage facility. As with capacity, there is no set definition regarding storage duration.
Battery storage is the fastest responding dispatchable source of power on electric grids, and it is used to stabilise those grids, as battery storage can transition from standby to full power in under a second to deal with grid contingencies.
