[“the cheapest way to store gw-level electricity is still pumped storage.” liu ke, dean of the school of innovation and entrepreneurship at the southern university of science and technology, said that battery storage alone cannot solve the problem. battery storage is equivalent to taking a bunch of plastic buckets when the yangtze river flood peaks, but it cannot solve the problem. ]

on september 9, a reporter from china business news learned from gcl energy (002015.sz) that the zhejiang jiande gcl pumped storage power station, the largest pumped-storage power station in east china with an investment of about 12.5 billion yuan by the company, is about to start construction.

it is understood that pumped storage is currently the most mainstream energy storage method. when the power system load is low, surplus electricity can be used to pump water from the lower reservoir to the upper reservoir for storage, and then release water to generate electricity when the load is peak.

the access of a high proportion of new energy and the rigid growth of electricity demand during peak hours have highlighted the role of pumped storage in power supply and energy transformation.

the power station is located near the east china power grid and the load center of zhejiang province, with a total installed capacity of 2.4 million kilowatts. after completion, it will mainly undertake the tasks of peak-shaving and valley-filling and energy storage for the east china power grid, and is scheduled to be put into operation before 2030. according to data disclosed by gcl energy, the power station is expected to install 6 reversible hydro-turbine generators with a single unit capacity of 400,000 kilowatts, with an estimated annual power generation of 2.52 billion kilowatt-hours, which can save about 480,000 tons of standard coal annually.

the power station is the largest pumped-storage power station in east china and the first and only pumped-storage power station currently invested and constructed by gcl energy.
