Doosan Enerbility has selected Austria-based Andritz to supply pump turbine units for the 500-megawatt Yeongdong pumped storage power plant in South Korea’s Chungcheong Province, the companies said.
Andritz said the project supports South Korea’s efforts to expand renewable energy capacity and strengthen grid stability as variable generation increases. The company added that it has previously delivered or rehabilitated around 40 pumped storage units in the country, with a combined capacity of more than 1 gigawatt.
“As we move toward a net-zero carbon future, energy storage has never been more important,” Alexander Schwab, senior vice president for market management at Andritz Hydropower, said in a statement.
“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,” Schwab added.
Under the contract, Andritz will be responsible for the design and supply of two pump turbine units, motor-generators and auxiliary systems, as well as digital control, governor and protection systems. Its scope also includes installation supervision and commissioning services.
The Yeongdong pumped storage plant is being developed jointly by Doosan Enerbility and Korea Hydro & Nuclear Power. Completion of the project is scheduled for 2030, the companies said.
