On 8 May, a Swedish delegation, led by Anne Höglund, Acting Swedish Ambassador in Seoul, visited the Wando-Dong Jeju 3 (Jeju 3) HVDC Converter Station on Jeju Island, South Korea.

During the visit, the delegation received a safety briefing and was introduced to Hitachi Energy’s HVDC technology. They had the opportunity to explore the site, including the converter stations, valve hall, and control room. Hitachi Energy's voltage-source converter (VSC) symmetrical monopole HVDC technology, capable of injecting 200 MW of power into the grid with enhanced stability and reliability, was showcased.

The Jeju 3 project, developed in collaboration with Korea Electric Power Corporation (KEPCO), aims to meet the growing electricity demand by establishing an advanced HVDC link. The converter stations, which convert power from AC to DC and vice versa, will facilitate bidirectional power transfer through subsea DC cables. This HVDC solution will improve the efficiency of the island's interconnections, stabilize the grid, and minimize the risk of outages.

The visit highlighted the successful implementation of HVDC solutions at Jeju 3 and their role in ensuring a reliable power supply. The Swedish delegation expressed pride in Hitachi Energy's pioneering HVDC technology, which originated in Sweden 70 years ago and has since been deployed in HVDC projects worldwide. The delegation recognized the potential of HVDC technology to provide millions of consumers with clean electricity, contributing to global efforts towards carbon neutrality.

The Jeju 3 project represents a significant milestone for Korea as it is the country's first Voltage-Source Converter installation. This project will enhance grid stability and reliability on Jeju Island and support South Korea's goal of making Jeju Province carbon-free and powered entirely by renewable energy by 2030.
