The capacity of an energy storage station signifies the maximum amount of electricity it can store and subsequently release. This characteristic is typically measured in megawatt-hours (MWh) or gigawatt-hours (GWh). The capacity of the storage system directly influences output. . Building too much storage can result in poor economics and building too little storage may result in insufficient energy to address the targeted applications. This brief provides various considerations for sizing the energy capacity of energy storage assets.
