Doosan Enerbility has awarded international technology group ANDRITZ a contract to design and supply key equipment for the Yeongdong pumped storage power plant in Chungcheong Province, South Korea.
Under the agreement, ANDRITZ will provide two pump turbine units, motor-generators, and related auxiliary systems. The scope also includes key components for the turbines and generators, as well as ANDRITZ’s digital control system, turbine governors, and protection systems. Installation supervision and commissioning services are also part of the contract. The order has been recorded in ANDRITZ’s fourth-quarter 2025 order intake. The plant is scheduled for completion in 2030.
The Yeongdong pumped storage project forms part of South Korea’s strategy to expand renewable energy capacity and strengthen grid stability. The country plans to add 5.7GW of pumped storage capacity by 2037 to support the integration of intermittent renewable energy sources such as wind and solar.
With a planned capacity of 500MW, the Yeongdong pumped storage facility is expected to play a role in balancing electricity supply and demand. ANDRITZ has previously delivered or rehabilitated around 40 hydropower units in South Korea, representing a combined installed capacity of more than 1GW.
Alexander Schwab, Senior Vice President Market Management at ANDRITZ Hydropower, said: “As we move toward a net-zero carbon future, energy storage has never been more important. As the most proven, reliable, and cost-effective energy storage technology, pumped storage is a key enabler for the energy transition that allows efficient energy management by balancing energy demand and supply, especially in an energy landscape increasingly dominated by intermittent energy sources such as wind and solar.”
The project is being developed jointly by Doosan Enerbility and Korea Hydro & Nuclear Power (KHNP). KHNP is South Korea’s largest electricity producer, supplying approximately 30% of the country’s electricity and expanding investment in pumped storage technology to support grid flexibility.
