The plant uses water from the upper reservoir to generate electricity during the peak demand periods of the day. At night, excess power on the grid generated by conventional coal and nuclear plants is used to pump water to the upper reservoir. • The upper Bedford Dam on Bedford stream, a tributary of the , was completed in April 2011. It is a 39 m (128 ft) tall . It has a 22,400,000 m (18,200 acre⋅ft) w. [pdf]

Since breaking ground in 2021, this pumped storage hydropower (PSH) facility has been storing sunshine (well, solar energy) in liquid form. With 350 MW capacity and 6 hours of storage, it's like a giant Lego set for power engineers. Who Cares About Water Going Up and Down? [pdf]
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 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 large. [pdf]
