Power capacity and storage capacity measure two very different things. Storage capacity (also known as energy capacity) measures the total amount of electricity a battery can store. The spec indicates how much electricity a battery can deliver over time before needing to be recharged. This metric is usually provided in watt-hours (wH) or
levels of renewable energy from variable renewable energy (VRE) sources without new energy storage resources. 2. There is no rule-of-thumb for how much battery storage is needed to integrate high levels of renewable energy. Instead, the appropriate amount of grid-scale battery storage depends on system-specific characteristics, including:
