Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in joules or kilowatt-hours and their multiples, it may be given in number of hours of electricity production at power plant nameplate capacity; when storage is of primary type (i.e., thermal or pumped-water), output is sourced only with the power plant embedded storage system.
As of 2018, the energy storage system is still gradually increasing, with a total installed grid capacity of 175 823 MW [ 30 ]. The pumped hydro storage systems were 169557 GW, and this was nearly 96% of the installed energy storage capacity worldwide. All others combined increased approximately by 4%.

One kilowatt-hour is defined as the amount of energy consumed by a device in one working hour at a constant rate of one kilowatt. The SI unit of energy is joule. Therefore, the relationship between commercial and SI units of energy is: 1 kWh = 1kW x 1h = 1000W x 1h = 1000 (J/s) x 3600 s = 3.6 x10 6 J. Q4.
