LS Cable has secured a contract for the second phase of the Korea Electric Power Corporation's (KEPCO) East Coast to Seoul high-voltage direct current (HVDC) project. Following its participation in the first phase last year, the company has once again demonstrated its competitiveness in the HVDC sector by engaging in this critical national power grid project.
According to industry sources on June 15, LS Cable won the turnkey contract for the second phase of the East Coast to Seoul HVDC project, which includes the East Coast to East Seoul segment. The supply scale is approximately 880 billion won for the first phase and about 1.46 trillion won for the second phase, totaling 2.34 trillion won.
The East Coast to Seoul HVDC project aims to transmit large amounts of electricity generated in the East Coast region to the capital area. As the distance between power generation sites and demand areas increases, this project is considered essential infrastructure for enhancing the stability of power supply in the Seoul metropolitan area.
This project will utilize 525kV, 90-degree HVDC cables, recognized for their world-leading transmission capacity. LS Cable has independently developed and commercialized the 500kV HVDC cable, marking a significant milestone as the first in the country to do so, and has now completed the commercialization of high-capacity products.
The power industry views the repeated bottlenecks in transmitting electricity from the East Coast as a key issue, highlighting the need for expanding HVDC networks that are advantageous for long-distance, high-capacity transmission to ensure future power supply stability.
LS Cable has also accumulated experience in HVDC projects both domestically and internationally. In Korea, it has worked on the Jeju 2 and 3 linkage projects and the North Dangjin-Godeok phases 1 and 2. Internationally, the company secured contracts worth approximately 3 trillion won for a high-voltage power grid project led by the German transmission system operator TenneT.
HVDC technology is advantageous for long-distance transmission with lower losses compared to alternating current systems. As demand for electricity rapidly increases due to the expansion of renewable energy, AI data centers, and investments in advanced industries, the importance of power grid investments is also growing.
"The HVDC project is directly linked to the stability of the national power grid, so not only technical capability but also proven commercialization experience in actual power networks is crucial," said Kim Hyung-won, head of LS Cable's Energy and Construction Business Division. "Based on our experience in major domestic and international HVDC projects, we will actively participate in the West Coast Energy Highway project as well."
