Frequency Regulation

Term from Energy Storage industry explained for recruiters

Frequency Regulation is a service provided by energy storage systems to help keep the power grid running smoothly. Just like a conductor keeps an orchestra playing at the right speed, frequency regulation keeps the electrical grid operating at the correct frequency. When too much or too little power is on the grid, energy storage systems can quickly add or remove power to maintain balance. This is becoming increasingly important as more renewable energy sources like wind and solar are added to the grid, since their power output can vary throughout the day.
