By integrating with solar systems pumped-hydro storage converts renewable electrical energy (solar) into mechanical energy and vice versa. The solar energy received by pumped hydro system is used to pump water from the lower reservoir to the upper one to be release during peak load hours (Canales et al., 2015).
Mechanical storage systems work on the basis of storing available and off-peak excessive electricity in the form of mechanical energy. Once the demand for electricity power overcome the available energy supply, the stored energy would be release to meet with the energy demand.
