When it comes to power storage, understanding the relationship between battery capacity and its stated nominal or rated capacity is crucial. The nominal capacity of a battery is the amount of energy it can store under certain conditions, and is usually indicated in ampere-hours (Ah) or watt-hours (Wh).
Complicating the analysis of energy storage as a source of peaking capacity is the significant variation in regional grid conditions, especially related to increased and varying mixes of VRE. In
