EVN Deputy General Director Pham Hong Phuong inspected the construction site of Bac Ai Pumped Storage Hydropower Plant - Khanh Hoa Province
On the morning of January 25th, EVN Deputy General Director Pham Hong Phuong and the Group's working delegation visited to inspect the construction progress of the Bac Ai Pumped Storage Hydropower Plant Project (Bac Ai Tay commune, Khanh Hoa province).
The Bac Ai Pumped Storage Hydropower Plant Project (4 turbines, total capacity of 1,200MW) plays a crucial role in "peak shaving and valley filling" of the load diagram. When completed (expected in 2030), Vietnam's first pumped storage hydropower plant will also be the largest and most modern pumped storage hydropower plant in Southeast Asia.
