Introduction

In order to cope with both high and low load situations, the storage of electricity is of great importance. However, the large-scale storage of electricity in the grid is still a major challenge and subject to research and development. 


The following technologies and approaches can, or are hoped to, provide a solution to storing electricity and balancing supply and demand in modern electricity grids.

Pump storage hydropower

A pumped storage hydroelectricity system (PSH) consists of two water reservoirs at different elevations. Low-cost surplus electric power is typically used to pump water into the upper reservoir. During periods of high electricity demand, the stored water is released through turbines to generate electricity.[1][2]
