Since they do not have any mechanical parts, battery storage power plants offer extremely short control times and start times, as little as 10 ms. They can therefore help dampen the fast oscillations that occur when electrical power networks are operated close to their maximum capacity or when grids suffer anomalies. These instabilities – fluctuations with periods of as much as 30 sec.
