Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of used by for . A PSH system stores energy in the form of of water, pumped from a lower elevation to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through to produce electric power. Pumped hydro storage power plants function like "giant batteries", utilizing surplus electricity during off-peak hours to pump water from a lower reservoir to an upper reservoir. During peak demand periods, this stored water is released to generate electricity.
[pdf] It is the first large, pumped-storage power station planned for Northeast China, with total capacity of 1200 MW. The main structures include the upper reservoir, the diversion tunnel, the underground powerhouse and the switchyard, and the lower reservoir.
[pdf] The following page lists all power stations that are larger than 1,000 in installed generating capacity, which are currently operational or under construction. Those power stations that are smaller than 1,000 MW, and those that are decommissioned or only at a planning/proposal stage may be found in regional lists, listed at the end of the page.
