Calculate the capacity of the BESS: To calculate the capacity of the BESS, simply multiply the rated energy of the battery by the DOD: Capacity (kWh) = Rated Energy (kWh) * Depth of Discharge (%) For example, if the battery has a rated energy of 100 kWh and a DOD of 80%: Capacity (kWh) = 100 kWh * 0.80 = 80 kWh.
The energy stored in a battery is calculated by multiplying the voltage of the battery by the capacity of the battery in ampere-hours. For example, a battery with a capacity of 1000 mAh and a voltage of 3.7 volts would have an energy storage capacity of 3.7 watt-hours (Wh).
Of the 4.7 GW of installed energy storage capacity in the UK, battery energy storage systems (BESS) account for only about 2.1 GW. Most of the current capacity, 2.8 GW, comes from pumped hydro storage – a form of turbine-powered hydroelectric storage where water moves between two reservoirs at different heights.
Under a yearly timescale, the optimal DER capacity allocation is carried out to meet the demand growth, while the investment decisions of BESS are made periodically to yield the optimal sizing, type
Small-scale battery energy storage. EIA''s data collection defines small-scale batteries as having less than 1 MW of power capacity.

That means you need many hours of energy storage capacity (megawatt-hours) as well. The study also finds that this capacity substitution ratio declines as storage tries to displace more gas capacity. "The first gas plant knocked offline by storage may only run for a couple of hours, one or two times per year," explains Jenkins.
The SOC and SOH are the key metrics that describe the performance of the battery and help predict its future behavior. The state-of-charge shows the amount of electric charge left in the battery. It''s expressed as a percentage that ranges from 0% to 100% depending on the charge level.
