The three quantities are related as follows: Duration = Energy Storage Capacity / Power Rating. Suppose that your utility has installed a battery with a power rating of 10 MW and an energy capacity of 40 MWh. Using the above equation, we can conclude that the battery has a duration of 4 hours: Duration = 40 MWh / 10 MW = 4 hours.
