Caomaogou pumped storage power station

Where is Shimogo pumped storage power station located?

The Shimogo Pumped Storage Power Station (Japanese: , Hepburn: Shimogō Hatsudensho) is a large pumped-storage hydroelectric power plant in Shimogō, Minamiaizu, Fukushima Prefecture, Japan. With an installed capacity of 1,000 megawatts (1,300,000 hp), the system is one of the largest pumped-storage power stations in Japan.

Can pumped storage power stations be built among Cascade reservoirs?

The construction of pumped storage power stations among cascade reservoirs is a feasible way to expand the flexible resources of the multi-energy complementary clean energy base. However, this way makes the hydraulic and electrical connections of the upper and lower reservoirs more complicated, which brings more uncertainty to the power generation.

Can pumped storage stations be used as energy storage support?

With China continuously scaling up the construction of integrated clean energy bases like “hydro-wind-storage” and new energy bases such as “Shagohuang”, pumped storage stations, especially variable-speed ones, will be more widely applied as energy storage support in regional grids (China Power, 2023).

What is the largest pumped-storage power station in the world?

Main construction was completed in late 2021, and became the largest pumped-storage power station in the world with an installed capacity of 3,600 MW. The 12th and final turbine began commercial operations in August 2024.

Can pumped storage power stations support a high-quality power supply?

Hence, to support the high-quality power supply, this research explores the complementary characteristics of the clean energy base building different types of pumped storage power stations, and recognizes the efficient operation intervals of the giant cascade reservoir.

How do pumped storage power stations work?

As the most mature and cost-effective energy storage technology available today, pumped storage power stations utilize excess WPP to pump water from a lower reservoir (LR) to an upper reservoir (UR).
