Frequency Regulation
A reliability service that maintains the electricity system frequency at its required operating level by continuously balancing electricity supply and demand.
Electric power systems in North America operate at a frequency of approximately 60 hertz (Hz).
Small differences between electricity supply and demand can cause the system frequency to increase or decrease.
Frequency regulation resources automatically adjust their output or consumption to correct these small imbalances and maintain stable system frequency.
Frequency regulation is typically provided by generators, energy storage systems, or other fast-response resources.
A battery energy storage system may rapidly charge or discharge electricity to help maintain system frequency.
