Abstract: Relying on the terrain elevation difference and water system resources of the Changbai Mountain area in eastern Jilin, the clustered construction of a pumped storage base with an installed capacity of ten million kilowatts constitutes a major energy strategic project of Jilin Province. At present, Baishan Pumped Storage Power Station and Dunhua Pumped Storage Power Station have been put into operation in Jilin Province, while Jiaohe Pumped Storage Power Station is scheduled to be commissioned before 2030. Jingyu Pumped Storage Power Station, Helong Pumped Storage Power Station and Tala River Pumped Storage Power Station have obtained project approval. Antu Pumped Storage Power Station, Tonghua Pumped Storage Power Station and Wangqing Pumped Storage Power Station are in the preliminary work stage and are expected to be successively put into operation during the 16th Five-Year Plan period. After full commissioning, a complementary clean energy pattern featuring pumped storage in the east and wind & photovoltaic power in the west will take shape. The large-scale grid connection of pumped storage units will exert significant impacts on the power grid framework of Jilin Province and the provincial new energy accommodation rate.
