in china The world’s largest pumped storage hydroelectric power plant entered service. Located in Fengning County of Hebei Province, near Beijing and Tianjin, the facility is an important part of China’s renewable energy infrastructure and will support 10 GW of wind and solar power plants located in the surrounding area.

It has a storage capacity of 40 GWh

The project, implemented by the State Grid Corporation of China, was completed in 11 years with an investment of 2.6 billion dollars. 40 GWh The facility, which has energy storage capacity, 12 reversible pump turbines, each with a capacity of 300 MW It is located. These turbines in total 3,6 GW can generate power. It is stated that the facility has an annual electricity generation capacity of 6.61 TWh and 8.71 TWh electricity storage capacity.

Fengning Pumped Storage Plant has a capacity of 45.04 million cubic meters. upper reservoir and a capacity of 71.56 million cubic meters lower reservoir It is located. When the upper reservoir reaches full capacity, the power plant for 10.8 hours It can store enough energy to run at full capacity, which equates to a capacity of approximately 40 GWh.

One of the prominent features of the power plant is underground powerhouse, the largest of its kind. The giant structure has a length of 414 meters, a height of 54.5 meters and a width of 25 meters. Additionally, there is supporting infrastructure consisting of 190 underground tunnels with a length of more than 50 kilometers.

The plant uses state-of-the-art variable speed pump turbine technology, which provides flexible load adjustments and faster frequency response for the pumping operation. In this way, it can balance the grid by quickly reacting to instantly changing renewable energy sources such as wind and solar.

Today, increasing renewable energy sources make energy storage important. Although lithium-ion battery-based energy storage systems have become widespread in recent years, pumped storage facilities are used to store large amounts of electricity in places with suitable geographical conditions (such as our country). A cheap, efficient and clean alternative stands out as.

China is also making significant investments in these facilities. by the end of 2024 40 GW In countries with pumped storage capacity, under construction 53 GW There is a capacity facility.
