A New Approach to Pumped Storage Hydropower

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 …

Storage Hydropower

Abstract. Pumped hydropower storage (PHS), also known as pumped- storage hydropower (PSH) and pumped hydropower energy storage (PHES), is a source-driven plant to store electricity, mainly with the aim of load balancing. During off-peak periods and times of high production at renewable power plants, low-cost electricity is consumed to …

Trends and challenges in the operation of pumped-storage hydropower plants …

The traditional operation of PSHPs is mainly focused on satisfying the load by means of the so called hydro-thermal coordination. Thus, the water is pumped during off-peak hours when the demand is low, and it is released afterwards during peak-hours with an overall round-trip efficiency in the range of 70–80%.

Pumped storage plants can operate with seawater, although there are additional challenges compared to using fresh water, such as saltwater corrosion and barnacle growth. Inaugurated in 1966, the 240 MW Rance tidal power station in France can partially work as a pumped-storage station. When high tides occur at off-peak hours, the turbines can be used to pump more seawater into the reservoir than the high tide would have naturally brought in. It is the only larg…
