New main transmission line to strengthen the main grid’s transmission capacity from the west coast to Southern Finland

Fingrid is building a new 400-kilovolt main grid transmission line from Kalajoki to Jämsä to transmit electricity from the major wind power production hub on the west coast to consumption sites elsewhere. The transmission line, known as the Lowlands Line, will be completed in 2027. It will enable new customer connections to the main grid and improve the overall security  of the power system.

Establishing electricity production facilities in Ostrobothnia increases the need for north-to-south electricity transmission.The volume of wind power production on the west coast has soared: approximately 5,000 megawatts of wind power will be built. A significant amount of clean, renewable electricity production has been built along the west coast, while the volume of production from fossil fuels has declined in Southern Finland. 

The new 400-kilovolt Lowlands Line will increase the transmission capacity from the west coast to Southern Finland. The project entails the construction of three new substations in addition to the transmission line. These will enable new renewable electricity production in areas where main grid connections have so far been impossible. Reinforcing the north–south transmission capacity will also boost the electricity market’s efficiency and enable Finland to remain a single price area in the electricity market.

Investments strengthen Finland’s position as a competitive country for clean energy investments

The Lowlands Line to strengthen electricity transmission on the west coast will be one of Fingrid’s most important investment projects in the coming years.

The project will be completed in phases. The transmission line section between Jylkkä and Alajärvi will be completed in 2027, and the section between Alajärvi and Toivila will be completed in 2028. A separate transmission line from Åback to Nokia is planned to strengthen the power system in the southern part of the west coast. This line should also be completed in 2028.

Fingrid plans to invest approximately EUR 4 billion in the main grid over the next ten years to power the green transition. The planned projects are based on forecasts of Finland’s future electricity production and consumption structure. One precondition for the realisation of the investment programme is a licensing and regulatory environment that supports the main grid investments.

Reinforcing the main grid will boost Finland’s internal electricity transmission capacity, strengthen cross-border connections, and enable new customer projects to connect to the main grid.
