What is thermal energy storage? Thermal energy storage means heating or cooling a medium to use the energy when needed later. In its simplest form, this could mean using a water tank for heat storage, where the water is heated at times when there is a lot of energy, and the energy is then stored in the water for use when energy is less plentiful.
4.2.1 Operating Principle. Pumped hydroelectric storage (PHES) is one of the most common large-scale storage systems and uses the potential energy of water. In periods of surplus of electricity, water is pumped into a higher reservoir (upper basin).

You know the basic concept of hydroelectric power production. To understand it better, think of it as using gravity and water to produce electricity.
Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).
When there is excess power in the grid the process is reversed, the water in the lower reservoir is pumped back to the upper reservoir using electricity. This captures the energy like charging a battery. Combined with solar and wind generation, pumped storage hydropower is perfect companion.
Pumped storage technology provides a long-term and economical energy solution. Unlike other hydroelectric plants, PSH needs fewer turbines to serve in peak hours since it is free from climate dependencies. PSH can be handy in emergency situations like flooding by acting as a water storage option.
The water from the upper reservoir is released through hydraulic turbines to produce energy during peak load hours. This sub-section presents the review of existing, if any, and the theoretical studies reported in the literature on photovoltaic based pumped hydroelectric energy storage systems. Fig. 7.
