Routes for Hanhikivi 1 nuclear power plant power lines chosen

Fennovoima has decided on routes for the power lines connecting Hanhikivi 1 nuclear power plant to the national grid.

The chosen route alternative (marked A1 in the map below) was drawn during the Environmental Impact Assessment (EIA) procedure based on feedback received on the different route options. The selected route runs the first of about four kilometers alongside the access road to the Hanhikivi 1 nuclear power plant.

Fennovoima’s nuclear power plant will be connected to the electric grid with 110 and 400 kV power lines at Hanhela and Valkeus substations. These Fennovoima’s connecting lines will be located in Pyhäjoki and Raahe municipalities.

For a distance of seven kilometres, the 110 kV lines run in parallel with a 110 kV power line being prepared by Puhuri Oy. Fennovoima and Puhuri are in discussions over collaboration in the parallel power line projects.

In connection with the Hanhikivi 1 project, the national electricity transmission grid company Fingrid Oyj will strengthen its own grid in Pyhäjoki, Raahe, Merijärvi and Kalajoki municipalities.

Field surveys will start early in the year

More detailed design of the power line routes has begun and will continue until 2018. The field surveys required for construction will start early this year. Land owners on the power line route will be contacted prior to starting the field surveys. The construction of the power lines has been scheduled to take place in 2019–2023.
