Battery storage capacity refers to the maximum amount of electricity a unit can store when fully charged. Not all batteries can be safely operated until fully discharged. For example, you should never discharge a lead acid battery below 50% of its total capacity, as you will shorten its lifespan.

Capacity refers to the maximum amount of power available from an electric resource or the maximum capability of an electric device to transmit power. There are a variety of uses of the word capacity in the electric grid: Nameplate capacity for a generation resource is its maximum output, measured in megawatts (MW). The nameplate capacity is
Small-scale battery energy storage. EIA''s data collection defines small-scale batteries as having less than 1 MW of power capacity. In 2021, U.S. utilities in 42 states reported 1,094 MW of small-scale battery capacity associated with their customer''s net-metered solar photovoltaic (PV) and non-net metered PV systems.
The rated capacity of a generation unit, also known as the maximum power rating, defines the maximum power in megawatts that the unit is designed to provide to the grid. While the unit may be able to produce electricity at a higher level, it will reduce its life in doing so. Many types of generation units can be operated at levels well below

The rated capacity of a power station is nearly the maximum electrical power that the power station can produce. Some power plants are run at almost exactly their rated capacity all the time, as a non-load-following base load power plant, except at times of scheduled or unscheduled maintenance.
In equipment which primarily dissipate electric power or convert it into mechanical power, such as resistors, and speakers, the power rating given is usually the maximum power that can be safely dissipated by the equipment. The usual reason for this limit is heat, although in certain electromechanical devices, particularly speakers, it is to prevent mechanical

A battery storage power station, or battery energy storage system (BESS), is a type of energy storage power station that uses a group of batteries to store electrical energy. 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.
