In order to promote the rapid development of pumped storage, meet the needs of new power system construction and large-scale and high proportion of new energy development, and help achieve the goal of carbon peak and carbon neutrality, the National Energy Administration recently issued the "Pumped Storage Medium and Long Term Development Plan (2021-2035)" (hereinafter referred to as the Plan).
[pdf] Located in Bath County, Virginia, this facility is one of the largest pumped storage hydroelectric power plants in the world, with a capacity of more than 3,003 megawatts.
[pdf] 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 as water moves down from one to the other (discharge), passing through a turbine.
[pdf] Compared to traditional energy storage technologies, pumped storage has three core advantages: Firstly, ultra-long service life, with a design life of over 50 years, far exceeding the 10–15 years of electrochemical energy storage; Secondly, large-capacity regulation capability, with a single station’s installed capacity reaching up to 1 million kilowatts; Thirdly, low life cycle costs, with a levelized cost of electricity that is only 1/3 to 1/2 of that of electrochemical energy storage.
[pdf] Recently, the Huangcaoyuan Pumped Storage Power Station in Daixian County, Shanxi Province, which is a key project in the national "14th Five Year Plan" for energy planning, has officially launched the bidding process for its key preliminary projects - the design, procurement, and construction general contracting (EPC) of the ventilation and safety tunnel and the access tunnel.
[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.
