Abstract: Abstract Pumped hydroelectric storage is currently the only commercially proven large‐scale (>100 MW ) energy storage technology with over 200 plants installed worldwide with a total installed capacity of over 100 GW . 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. Pumping and generating generally follow a daily cycle but weekly or even seasonal cycling is also possible with larger pumped hydroelectric storage plant. Pumped hydroelectric storage is a flexible form of electricity generation and can contribute many benefits to power systems operation. There has been a renewed commercial and technical interest in pumped hydroelectric storage recently with the advent of increased variable renewable energy generation and the development of liberalized electricity markets.
