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 (discharge) as water moves down through a turbine; this draws power as it pumps water (recharge) to the upper reservoir. PSH capabilities can be characterized as open loop ...
Hydropower is the leading renewable energy technology toward low-carbon electricity generation. Hydropower development needs better visibility on its direct and indirect revenues on the grid, society, and environment and is key to attract investment at a large scale (DFID, 2009).).
