Water is pumped from the lower reservoir up into a holding reservoir. Pumped storage facilities store excess energy as gravitational potential energy of water. Since these reservoirs hold such large volumes of water, pumped water storage is considered to be a large scale energy storage system.
Penstock is used to connect the two reservoirs. The key components of a pumped storage power station are the hydro turbine and pump, which usually adopt the form of bladed hydraulic machinery. The mechanical energy of the water and the mechanical energy of the runner can be converted to each other.
This is a result of the energy lost pumping the water up into the reservoir. However, pumped storage is economical because of a net increase in revenue. This is because the electricity used to pump the water is less expensive than the electricity sold at the time of peak energy demand.
Pumped storage plants are a combination of energy storage and power plant. They utilise the elevation difference between an upper and a lower storage basin. Pumps driven by electric motor– generators move water from the lower to the upper basin, thereby storing potential energy.
