Doosan Selects ANDRITZ for Yeongdong Pumped Storage Plant

Doosan Enerbility has selected ANDRITZ to supply key electromechanical equipment for the Yeongdong pumped storage power plant in Chungcheong Province, South Korea. The facility is designed to strengthen grid stability as the country increases the share of variable renewable energy sources.

South Korea plans to add 5.7 GW of pumped storage capacity by 2037 to support the integration of wind and solar power while maintaining system reliability. With an installed capacity of 500 MW, the Yeongdong project represents a significant contribution to this national energy storage strategy.

ANDRITZ’s scope of supply includes the design of two pump-turbine units, motor-generators, and associated auxiliary systems. The company will also provide its digital control system, turbine governors, and protection systems, alongside installation supervision and commissioning services. Completion of the plant is scheduled for 2030.

Pumped storage technology plays a central role in balancing electricity supply and demand by storing excess energy during periods of low demand and releasing it during peak consumption. In energy systems with growing shares of intermittent generation, such as solar and wind, this capability is essential for maintaining frequency stability and operational flexibility.

The Yeongdong project is being developed jointly by Doosan Enerbility and Korea Hydro & Nuclear Power, South Korea’s largest power producer. ANDRITZ has previously delivered or rehabilitated around 40 hydropower units in the country, totaling more than 1 GW of installed capacity, underlining its experience in the South Korean pumped storage and hydropower market.
