GE Power has been awarded a $320m contract through its joint venture, KAPES, by Korea Electric Power Corporation (KEPCO) to provide equipment and expertise for a new transmission link in Seoul, capital of South Korea.
The company is to deliver a 4 GW HVDC power transmission link from the power complex located East of South Korea, to Seoul’s metropolitan area, a zone that represents around 40% of global Korean energy demand1.
With 51.3 million people, South Korea has experienced an almost 35 per cent growth in energy demand in the last decade alone. The country faces the ambitious challenge of providing efficient energy to its densely populated areas. This new HVDC project will increase the stability and reliability of the Korean electrical transmission grid by adding new routes for power supply.
GE together with KAPES will design and supply the overall HVDC system, a 500 kV HVDC Bipole with two converter stations, including valves, cooling system, converter transformers, filters, switchyard, and control system. This HVDC system has a reduced environmental impact compared with traditional alternating current (AC) system.
In 2014, through its KAPES joint venture, GE was awarded the 1.5 GW Buk-Dangjin–Godeok HVDC connection to transmit energy from the Dangjin power plant west of South Korea, to the densely populated area of Pyeongtaek (Godeok) and Seoul Metropolitan, about 35km east of Dangjin.
The project is currently in progress and will be completed end of 2019. 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.
