Transmission line corridor selected for Gulf of Riga offshore wind farm
A transmission line corridor connecting a planned offshore wind farm in the Gulf of Riga to the mainland grid has been selected.
As part of the government's special state plan, the most suitable route has been identified for a transmission line to link the planned offshore wind farm in the Gulf of Riga with the mainland power grid. The corridor was chosen through an environmental impact assessment and in cooperation with local governments and communities.
The connection will begin as undersea cables in the Gulf of Riga and come ashore at Jaagupi in Häädemeeste Municipality. From there, it will continue as an underground cable to the Arumetsa substation. The underground cable was chosen for the coastal section due to dense population and nature conservation requirements.
From Arumetsa onward, the connection will run as two 330-kilovolt overhead power lines through Häädemeeste and Saarde municipalities to the new Kärsuveski substation. The planning solution and environmental impact assessment report will be on public display from June 19 to July 26, during which time everyone can provide input. Based on the feedback, the plan will be reviewed and, if necessary, supplemented before being approved at the end of 2026.
The government initiated the state special spatial plan in 2022 after Enefit OÜ proposed building an offshore wind farm with a capacity of up to 1,000 megawatts in the Gulf of Riga. The purpose of the plan is to design a connection to transmit electricity from the offshore wind farm to the mainland grid and ultimately to consumers.
