There is a certain need for energy storage. The main factor to measure the grid stability is the net frequency. If the load is higher than the power generation, the frequency drops. The allowed tolerance is 50 Hz ±0.2 Hz. When the frequency drops below 49.8 Hz, the power generation companies activating their reserves.
