Energy Capacity (MWh) indicates the total amount of energy a BESS can store and subsequently deliver over time. It defines the duration for which the system can supply power before recharging is necessary. For instance, a BESS with an energy capacity of 20 MWh can provide 10 MW of power continuously for 2 hours (since 10 MW × 2 hours = 20 MWh).
The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery. The unit of Ah is commonly used when working with battery systems as the battery voltage will vary throughout the charging or discharging cycle.
Base year costs for utility-scale battery energy storage systems (BESSs) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2023). The bottom-up BESS model accounts for major components, including the LIB pack, the inverter, and the balance of system (BOS) needed for the installation.
The charging/discharging rates affect the rated battery capacity. If the battery is being discharged very quickly (i.e., the discharge current is high), then the amount of energy that can be extracted from the battery is reduced and the battery capacity is lower.
The research results indicate that during peak hours at the charging station, the probability of electricity consumption exceeding the storage battery's capacity is only 3.562 %. After five years of operation, the charging station has saved 5.6610 % on electricity costs.
For context, the largest capacity of a GivEnergy battery storage container is 500 kilowatts (kW). That’s roughly 196 times smaller than the Pillswood battery storage facility. As with capacity, there is no set definition regarding storage duration.
