Editing Energy storage (section)

== Capacity ==
'''Storage capacity''' is the amount of energy extracted from an energy storage device or system; usually measured in [[joule]]s or [[Kilowatt hour|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.<ref>{{cite web
