The Haesong project is planned to be built off the west coast of Shinan, Jeonnam, and consists of two 504 MW phases, Haesong 1 and Haesong 3.
In June 2025, Haesong Offshore Wind signed a grid interconnection agreement (GIA) with Korea Electric Power Corporation (KEPCO) for the Haesong Offshore Wind 1 and 3 projects. This agreement enables the connection of 1 GW of renewable energy generated from the Haesong Offshore Wind 1 and 3 projects to KEPCO’s grid.
