Pump storage hydroelectricity is an efficient way to temporarily store energy. This technique requires to store temporarily a large volume of water in an upper reservoir, and to release it through turbines to the lower reservoir, to produce electricity. Recently, the idea of using old flooded quarries as a lower reservoir has been evoked.

2.1 Pumped hydro storage (PHS) PHS is a large scale energy storage system. Its operating principle is based on managing the gravitational potential energy of water, by pumping it from a lower reservoir to an upper reservoir during periods of low power demand. When the power demand is high, water flows from the upper reservoir to the lower

As the National Hydropower Association (NHA) has well documented ( 2021 Pumped Storage Report ), pumped storage hydro is a vital tool in the renewable energy integration plans of the future. Many utilities already have pumped storage hydro and are benefiting from the storage, flexibility, and stability that it provides to their systems.
The potential energy stored in a pumped hydro storage system can be calculated using the formula: Potential energy (MWh) = Volume of water (m³) × height difference (m) × gravitational acceleration (9.81 m/s²) × water density (1000 kg/m³) × efficiency / 3,600,000.

Pairing an energy storage system (ESS) with a hydropower plant is a promising option to mitigate degradation effects. The choice of ESS as a supporting technology for hybridization is not random. ESSs are flexible, scalable, and can respond instantaneously to unpredictable variations in demand and generation.
The fundamental principle of pumped hydroelectric storage is to store electric energy in the form of hydraulic potential energy. Pumping typically takes place during off-peak periods, when both electricity demand and electricity prices are low. Generation takes place during peak periods, when electricity system demand is high.
