Renewal of transmission lines commenced on the Olkiluoto - Rauma lineMain grid interface reinforced at Eurajoki. Fingrid Oyj, which is responsible for the main electricity transmission grid in Finland, has launched the renewal of the 2x110 kilovolt (kV) Olkiluoto - Rauma transmission line between Olkiluoto and Junnala. This line project is part of the main grid connection arrangements required by the new nuclear power unit to be constructed at Olkiluoto.
The project, which started on 31 May through foundation work, is the first phase in reinforcing the main grid connection for Olkiluoto. Later, between 2005 and 2007, a 400 kV line will be built from Olkiluoto to Huittinen, and there will also be substations at both ends of the line.
The length of the line renewed within the current project is 10.5 kilometres, and it will be ready in January 2006. The line will run in Eurajoki from TVO’s power plant area to the separation point of the current 400 kV lines at Junnala. Existing line structures will primarily be renewed on the current right-of-way. The new line will deviate from the present route a little at Olkiluoto and in the Tahkoniemi - Junnala area, where a new 110 kV line will go under the 400 kV lines earlier than now.
The contractor in the transmission line project costing approx. 3 million euros is Empower Oy. The turn-key contract covers all engineering, construction and installation work and materials. The contract also includes replacement of some overhead ground wires on the 400 kV line between Seinäjoki and Ulvila.
