We are building a platform for a clean electricity system 

Fingrid publishes a main grid development plan every two years to outline the main grid’s development needs and planned investments for the next ten years.  In the draft of the main grid development plan 2024-2033, the investments in the main grid will rise from the previously estimated, slightly over three billion to four billion euros. The aim of the main grid investments is to create the conditions for Finland’s competitiveness in industrial investments and enable the achievement of carbon neutrality targets by 2035.

As part of the main grid development plan, Fingrid will strengthen electricity transmission capacity inside Finland and cross-border connections, as well as enable the connection of new customers to the main grid. Fingrid designs and builds transmission lines and substations on dozens of worksites annually. 

The Forest Line and Lake Line transmission line connections and innovative technical solutions that boost the grid’s transmission capacity ensure ample transmission capacity between Northern and Southern Finland and contribute to keeping Finland a single price area. Alongside its transmission line projects, Fingrid is building and modernising a record number of substations throughout Finland, enabling clean energy to be connected to the main grid.

In addition to strengthening the main grid, Fingrid is working on the Aurora Line electricity transmission connection to improve the cross-border connections with Sweden. The new connection will boost the cross-border capacity between the countries and reduce the price of electricity. The Helsinki 400 kilovolt power cable connection is also bringing the main grid to Helsinki. The project will address the needs and climate objectives of the growing city.

Whenever line routes are beign planned and in conjunction with transmission line maintenance work, Fingrid gives landowners, neighbors and other concerned parties an opportunity to express their views, to discuss the project and to co-operate in issues related to the project plan and its execution.

Projects on map

Fingrid’s map service shows the projects in Finland’s main grid.

The map allows the user to see project locations and open further information about projects. The map service also enables you to provide targeted feedback on Fingrid’s projects. The site is in Finnish.
