The final wind turbine has been installed at the Jeonnam 1 offshore wind farm in South Korea, the project’s wind turbine supplier Siemens Gamesa said via social media on 18 December.

Jeonnam 1, which has a nominal installed capacity of 96 MW, features Siemens Gamesa SG 10.0-193 DD wind turbines and is expected to provide enough renewable energy to power approximately 60,000 households once fully commissioned early next year.

Wind turbine installation at the project site, located 8.6 kilometres off the coast of Jaeun Island in the Jeonnam province, started in September 2024 and the wind farm produced first power in November.

The offshore wind farm, the first large-scale privately led project of this kind in South Korea, is owned by a joint venture between SK E&S (51 per cent) and Copenhagen Infrastructure Partners (49 per cent).

The joint venture, Jeonnam Offshore Wind Power, obtained an Electricity Business License (EBL) for Jeonnam 1 in 2017 and entered a grid connection agreement with KEPCO, the state-owned utility in South Korea, allowing the project to connect to the grid in 2024.

In 2022, Jeonnam 1 was awarded a 20-year fixed-price offtake agreement with Korea Hydro & Nuclear Power through Korea’s first wind offtake auction.

SK E&S and Copenhagen Infrastructure Partners (CIP) reached financial close for the project in October 2023.

The joint venture is also developing two additional phases of the Jeonnam offshore wind development, Jeonnam 2 and Jeonnam 3, with a total capacity of 800 MW.
