It is the first time that two different rated speeds (500/600 rpm) of pumped-storage units are arranged in the same powerhouse. The pump-turbine unit with a rated speed of 600 rpm and a unit capacity of 350 MW has the largest single unit capacity all over the world.

Through a clear planning process and suitable reward for investment, China has put in place a complete system for bringing forward the PSH capacity it has determined is necessary.
China''s pumped-storage installed capacity remains the largest in the world, but industry experts said relying solely on the State Grid for construction will no longer be sufficient
Abstract Pumped hydroelectric storage (PHS) is the most widely used electrical energy storage technology in the world today. It can offer a wide range of services to the modern-day power
This procedure is done for alternative storage durations of 8, 10, and 12 hours. Underlying data are site-specific, but for the ATB, resource classes are binned by capital cost so that each
Roddy Cormack, Senior Associate, Dentons commented: "Long duration energy storage and pumped storage hydropower in particular is pivotal in terms of giving our electricity
China is building pumped-storage hydropower facilities to increase the flexibility of the power grid and accommodate growing wind and solar power. As of May 2023, China had 50 gigawatts (GW) of operational pumped-storage capacity, 30% of global capacity and more than any other country.
He believes significant market growth for pumped hydro storage in China is expected, driven by the increasing integration of wind and solar power into the energy system. Pumped hydro storage serves as essential energy storage support for integrated clean energy bases, playing a pivotal role in the continued growth of renewables, he said.
China’s pumped-storage capacity is set to increase even more, with 89 GW of capacity currently under construction. Developers are seeking governmental approvals, land rights, or financing for an additional 276 GW of pumped-storage projects, according to the data from Global Energy Monitor. Pumped storage is a type of energy storage.
China's cumulative installed pumped hydro capacity exceeded 58 gigawatts (GW) by the end of 2024, with 7.75 GW of new capacity added in the past year alone, according to the China Renewable Energy Development Report 2024 released recently by the China Renewable Energy Engineering Institute.
The world's second-largest economy added 7.75 GW of pumped hydro in 2024, bringing its total installed pumped hydro capacity to 58.69 GW, the IHA said in a statement. More than 200 GW of such projects are under construction, it added, accounting for a third of all such projects under development globally.
China has been aggressively expanding its pumped hydro storage capacity in recent years, positioning these power plants as crucial "stabilizers" for its evolving electricity grid as the nation embraces a greater share of intermittent renewable energy sources, a recent industry report reveals.
