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.

In general, ES capacity value is determined by the plant''s ability to support demand under outage conditions – in this case, single and double network faults. It follows that a key factor in determining ES contribution is the duration of outages; the longer the outage duration, the more energy is required from ES.
