On November 5, 2026, the main project of Jilin Huadian Jingyu Pumped Storage Power Station was officially launched in Jingshan Town, Jingyu County. The project has shifted from the early preparation stage to the large-scale construction stage of core buildings such as underground powerhouses, water transmission systems, and upper and lower reservoirs. This is also the first major pumped storage project deployed by China Huadian in the Northeast region, which has been included in the national key energy project list for the 14th Five Year Plan.

Northeast long-term energy storage adds core hub

The total investment of the project is 11.6 billion yuan, with a total installed capacity of 1.8 million kilowatts. It is planned to be fully completed and put into operation by 2032. After being put into operation, the average annual power generation is 1.481 billion kilowatt hours, the average annual pumped water generation is 1.975 billion kilowatt hours, and the comprehensive cycle efficiency reaches 75%. After the power station is put into operation, it can save about 1.32 million tons of standard coal annually and directly reduce carbon dioxide emissions by about 3.46 million tons. It will become the core long-term energy storage hub within the Jilin power grid.

At the peak of the project construction, the number of local workers will reach 3000. During the construction period, the annual average new investment in fixed assets investment for the local government will be about 1.2 billion yuan. After the project is put into operation, the annual new tax revenue for the local government will be about 100 million yuan, directly driving the coordinated development of surrounding transportation, warehousing, culture and tourism and other supporting industries. The preliminary docking work of the project started in 2022 and successfully obtained project approval in 2024. Subsequently, the construction of land guarantee, four connections and one leveling, ventilation, and transportation tunnels was carried out, and all prerequisites for commencement were fully implemented.

Jilin power grid's peak shaving capacity has seen a significant increase in magnitude

After the power station is put into operation, it will fully undertake the core functions of peak shaving, valley filling, energy storage, frequency regulation, phase regulation, and emergency backup of Jilin power grid, greatly enhancing the consumption space of new energy in the province. At present, the installed capacity of wind and solar power in western Jilin continues to grow rapidly. A large amount of clean electricity was previously limited by the system's peak shaving capacity and could not be fully consumed. After the completion of this pumped storage power station, it will provide a large capacity energy storage carrier for the transfer of surplus green electricity across days, directly filling the important gap of long-term resource adjustment in Jilin power grid.Editor/Cheng Liting
