GE Commissions Final Phase of High-Voltage Direct Current Energy Highway in South Korea

The additional capacity will strengthen the supply of electricity to Godeok and Seoul Metropolis, accounting for 40% of South Korea’s energy consumption.

GE’s Grid Solutions business has been awarded by KAPES a contract in excess of $100 million to complete Korea Electric Power Corporation’s (KEPCO) second and final phase of the Buk Dangjin-Godeok high-voltage direct current (HVDC) transmission link. The final phase will add an additional 1.5 GW of transmission capacity to the existing 33-km link, supplying electricity from the Dangjin power plant to Godeok, home to one of the largest semi-conductor plants in the world, as well as to the Pyeongtaek city and the south of Seoul Metropolitan area. Together, these areas account for 40% of South Korea’s energy consumption.

In 2020, GE and KAPES, a KEPCO-GE joint venture, will complete the first 1.5 GW phase of the bi-pole HVDC link that runs across the Ansanman Bay from Dangjin to Godeok. With GE’s HVDC technology, KEPCO, Korea’s largest utility, was able to avoid the construction of a 100-km overhead line that an alternating current (AC) scheme would have required. Moreover, this solution provides additional supply into this high-growth region.

Compared to AC technology, HVDC lowers transmission costs and energy losses as well as having a smaller footprint, making it a more efficient and environmentally-friendly way to move electricity over long distances. With South Korea experiencing a 53% growth in energy demand within the last decade, and continuing to be one of the biggest energy consumers in the world, the Buk Dangjing-Godeok link is crucial to developing South Korea's transmission network to meet the nation's growing energy demand. 

“With this project, GE and KEPCO continue to reinforce the value of the KAPES joint venture.  The investment that has been made to transfer knowledge and localize GE’s HVDC technology continues to be a win-win partnership,” said Rajendra Iyer, GE’s Grid Solutions’ Integrated Solutions Leader. “GE is proud to be able to contribute to South Korea’s growing energy economy in this way.”

The KAPES joint venture between GE and KEPCO is a long-term strategic relationship to co-develop HVDC projects and increase Korean transmission grid capabilities based on GE technology. To date, GE and KAPES have been awarded six grid-critical HVDC projects in Korea, starting in 1994 when GE provided the original 300-MW HVDC bi-pole link for the 101-km, point-to-point submarine electric interconnector linking South Korea’s Jeju Island with the mainland.
