Capacity and capability determine the scale of a battery storage system. However, there are several other characteristics that are important for calculating the marketability and return potential of a Battery Energy Storage System (BESS). Here are the most important metrics for BESS.
Battery storage systems investigated ranged in size from 65 kWh/5 kW to 18MWh/3.6 MW (where the capacity of the line connecting the microgrid to the grid is 10 MW) , naturally depending on the size of the microgrid.
This is the energy that a battery can release after it has been stored. Capacity is typically measured in watt-hours (Wh), unit prefixes like kilo (1 kWh = 1000 Wh) or mega (1 MWh = 1,000,000 Wh) are added according to the scale. The capability of a battery is the rate at which it can release stored energy.
