Mainstream Renewable Power and Ocean Winds have secured a transmission service agreement (TSA) with Korea Electric Power (KEPCO) for the transmission of 1.125GW renewable energy from their KF Wind floating offshore project in South Korea.

The agreement encompasses two phases of the South Korean floating offshore wind project, namely the 375MW East Blue Power project and the 750MW KF Wind project.

The clean energy generated by these phases will be interconnected at KEPCO’s Shinonsan onshore station in Ulsan.

KF Wind project director Austin Park said: “This agreement marks a very important milestone in the development of KF Wind and a major step forward towards getting the project ready for construction.”

Located 80km offshore from Ulsan, the KF Wind project is a part of the 6GW Ulsan floating wind farm.

The South Korean floating offshore wind project is being developed by Mainstream Renewable Power, Ocean Winds and Kumyang Electric.

Ocean Winds is a joint venture (JV) formed in 2019 between Spanish renewable energy company EDP Renewables and France-based utility company ENGIE.

The KF Wind project covers an area of over 240 km2. It will feature 75 floating wind turbines.

Upon its completion, the KF Wind project is estimated to deliver clean energy to over 1.3 million households every year.

The KF Wind floating offshore project has secured the approvals of the environmental impact assessments from the South Korean Ministry of Environment, Trade and Industry.

Once commissioned, the Ulsan floating offshore wind cluster is said to become the world’s largest floating offshore wind area. This project is also anticipated to play a crucial role in supporting South Korea’s carbon neutrality goals.

Last year, Mainstream Renewable Power partnered with Ocean Winds to develop the second ScotWind floating offshore wind site located in Scotland with a capacity of 500MW.
