What are the gaojian pumped storage projects

How big is China's pumped-storage capacity?

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.

Why is China building pumped-storage hydropower facilities?

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.

Why is China ramping up pumped-storage hydroelectricity capacity?

[Photo/Xinhua] Clean power facilities gain ground on policy support, advantages over other new energy units China is ramping up pumped-storage hydroelectricity (PSH) capacity in an effort to boost new energy development and ensure stable operations of the grid, according to a recent industry report.

What is a pumped-storage plant?

Pumped-storage plants can store the excess wind and solar generation for later use. This supply management helps offset the variability in solar and wind. This flexibility is particularly important in China, which has a large and growing share of wind and solar power in its generation mix.

What is the Development Report of pumped storage industry 2021?

The report, Development Report of Pumped Storage Industry 2021, was published by the China Renewable Energy Engineering Institute on Friday. The total installed capacity of PSH in China increased 15.6 percent year-on-year to 36.39 million kW by the end of 2021, ranking tops in the world, the report said.

What is pumped storage?

Pumped storage is a type of energy storage. When demand is low (or supply is high), pumped-storage hydropower plants pump water from a lower reservoir to an upper reservoir. Later, when electricity demand is high (or supply is low), the water is released from the upper reservoir through a turbine into the lower reservoir, generating electricity.
