DL E&C announced on the 30th that it had held a signing ceremony for a ‘contract for the construction of Yeongdong Pumped-Storage Power Plant’ with Korea Hydro & Nuclear Power (“KHNP”) at the Radiological Health Institute in Jung-gu, Seoul. The signing ceremony was attended by Sang-Shin Park, the CEO of DL E&C, and Juho Hwang, the president of KNDP.
This project is to construct a 500MW pumped-storage power plant in Sangchon-myeon and Yanggang-myeon, Yeongdong-gun, Chnugcheongbuk-do, with a targeted completion in 2030. The power plant will generate enough power to supply to about 110,000 households annually. DL E&C received a letter of award from KHNP earlier this month, and entered into a contract. The contract is valued at KRW503.4 billion, and DL E&C will generally carry out civil engineering and construction work, including the upper and lower dams, underground power plant and water tunnels.
Pumped-storage power generation is a method of generating electricity after pumping up water from a lower dam to an upper dam using electricity obtained from renewable energy generation or cheap electricity generated in the dead of night, and then storing the water, and dropping the water from the upper dam to the lower dam to generate electricity when demand for electricity increases. It has the merits, including high stability, long lifespan of 40 to 60 years and large energy storage capacity
Renewable energy is gaining attention due to the global carbon neutrality policies, but is featured by instability in supply and demand depending on day or night, or weather conditions. To address this volatility, KHNP is going ahead with this project for pumped-storage power generation for the first time in 13 years. The last pumped-storage power plant built in Korea was the Yecheon Pumped-Storage Power Plant in 2011, which was also constructed by DL E&C.
In particular, ‘RBM (Raise Boring Machine)’ method will be applied to this project. It is a technology that creates a small hole in the bedrock, connects it to a vertical tunnel excavator equipped with a cutter (blade), and then rotates it to drill the bedrock. This technology is characterized by the shortened construction period and increased safety. DL E&C aims to successfully complete the project for Yeongdong Pumped-Storage Power Plant, leveraging this technology and close collaboration with KHNP.

At the signing ceremony, Sang-Shin Park, the CEO of DL E&C, said, “We are the construction company that completed the last pumped-storage power plant in Korea, and now, we are starting again after 13 years. We will do our best to ensure safety and quality- focused site management for the construction of Yeongdong Pumped-storage Power Plant.”
Juho Hwang, the president of KHNP said, “Pumped-storage power plant plays a huge role in not only strengthening national energy security but also in achieving carbon neutrality. We will strive to contribute to local economic revitalization, including creating jobs for local residents.”
