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 kilowatt-hours (kWh) for larger batteries.

Total Power Requirement (with Growth Factor) = Total Power Requirement x (1 + Growth Factor) = 59 kVA x (1 + 0.3) = 76.7 kVA. So the total power requirement with growth factor is 76.7 kVA. Now that you have determined the total power requirement, you can select a transformer that is capable of providing the necessary power.

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.
