Energy storage resources provide both high quality PFR and frequency regulation (secondary control) to electric grid systems. For example, in the PJM regulation market, each megawatt of energy storage provides regulation service that is the equivalent of 2.6 megawatts of traditional generation based on accuracy and performance.

Briefly explained, when the frequency exceeds the specified limit, the battery energy storage system (BESS) absorbs active power from the system (BESS charging), thus lowering the frequency. Conversely, when the frequency falls below the specified range, the BESS supplies active power to the system (BESS discharging),
