2. PUMPED HYDRO STORAGE

Pumped hydro storage represents one of the most established and economically viable methods for gravity energy storage. This approach utilizes two reservoirs at different elevations, creating a significant potential energy difference. When electricity demand is low, surplus energy is used to pump water from the lower reservoir to the upper reservoir. Conversely, when electricity demand surges, the stored water is released to flow back down through turbines, generating electricity.

A key benefit of pumped hydro storage is its ability to provide grid stability. Due to its scalability and rapid response capabilities, this method can effectively balance supply and demand fluctuations. Moreover, it plays a crucial role in integrating intermittent renewable resources such as wind and solar power, compensating for their variable output. By discharging stored energy during peak demand periods, pumped hydro systems alleviate pressure on conventional power plants, facilitating a smoother energy transition.
