Fingrid has updated its main grid development plan, with investments in the main grid rising 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.
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. A draft of the 2024–2033 development plan has now been published for stakeholders to comment on.
The development plan is the best current estimate of future investments in the main grid. The planned projects are based on various forecasts and assumptions about the future. These may change over time, which means that the implementation and timelines of the planned investments may change as well. Investment decisions on the projects included in the plan will be made separately once the need for the projects and their implementation are confirmed.
Investments in the main grid strengthen Finland''s position as a competitive country for clean energy investments
The investments estimated for 2024–2033 in the updated main grid development plan amount to EUR 4 billion. The rise in investments in the main grid is driven by industrial investments utilising clean energy and the electrification of society, which require an increase in emission-free electricity production and high security of energy supply.
"Finland''s rapidly growing renewable electricity production and the opportunities associated with it are attracting industrial activities that utilise clean and affordable electricity. This will result in an accelerating transformation of the energy system that will challenge the main grid to develop at an even faster pace to meet the needs of customers," Jussi Jyrinsalo, Senior Vice President at Fingrid, affirms.
Internationally, Finland presents itself as one of the world''s most interesting investment targets for projects based on renewable energy. According to an estimate by the Confederation of Finnish Industries, low-emission investments worth EUR 90 billion are already being planned in Finland.
The main grid connection enquiries received by Fingrid for clean electricity production and recently for green technology industrial projects in particular have continued to increase during the past year. Fingrid estimates that wind and solar power capacity may quadruple and, at the same time, industrial electricity consumption may double in the early 2030s.
Increasing electricity transmission capacity inside Finland and strengthening cross-border connections
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.
In order to increase cross-border capacity, the Aurora Line – a new 400 kV cross-border connection – is currently under construction between Finland and Sweden and is set for completion in 2025. Fingrid is also planning a new cross-border connection (Aurora Line 2) between the two countries, in collaboration with the Swedish transmission system operator. Additionally, Fingrid is planning a third direct current cable between Finland and Estonia, in unison with the Estonian transmission system operator.
There are plans to raise the transmission capacity between Northern and Southern Finland with several new 400 kV transmission line connections. The Lake Line from Vaala to Joroinen will be strengthened by 2026 and the Forest Line from Vaala to Central Finland by 2030. The new Ridge Line from Haapajärvi and Kajaani to Southern Finland should be ready in 2032. A new transmission connection from Rovaniemi in Northern Finland to Vaala is also being planned.
In addition, there are plans for two new 400 kV transmission line connections from Kalajoki and Kristinestad on the west coast to Southern Finland, which will enable the connection of new electricity production and consumption projects to the west coast. To enable the considerable wind power potential of Kainuu, a 400 kV meshed grid is being planned from Hyrynsalmi to Vaala and Muhos.
The investment programme also provides for several substation projects and the construction of compensation equipment to, for example, support the main grid as electricity generation by power park modules increases.
Responsible development of the main grid requires environmental consideration and smooth co-operation in project permit procedures
Investments in the main grid enable the transition to a clean electricity system and contribute to safeguarding the vital functions of society.
The implementation of main grid investments requires smooth progress in project permit procedures and positive co-operation with landowners and other stakeholders. The necessary environmental studies are carried out for investment projects, and their environmental impacts are being reduced and mitigated during the periods of planning, construction and operation as a whole.

Finland is undergoing a revolution in electricity production as society strives towards renewable and low-emission energy production.
Traditional fossil fuel power plants are closing in the south of Finland, while an increasing share of electricity is produced by wind power, mainly on the west coast and in the north. However, most of the country''s electricity demand has remained in the growth centres in the south, so electricity needs to betransmitted over long distances. This is piling the pressure on the power transmission grid.
"The power system has undergone a rapid transformation, and the grid cannot keep up unless we take action," says Petri Parviainen, Unit Manager, Main Grid Services, at Fingrid.
New wind power is growing at a rate of more than 1,000 megawatts per year, which is a significant addition to a system the size of Finland''s. Fingrid is building and reinforcing the transmission network: investments of EUR 4 billion are already planned.
But other methods are needed. Therefore, Fingrid is planning changes to connection fees and main grid service fees collected from network users in the hope of utilising the network more efficiently.
In addition to the fee for direct connections to the main grid, a regional power-based tariff is planned to be introduced on the "user pays" principle. In other words, there would be an additional charge for increasing the production in a production-heavy region or increasing consumption in a consumption-heavy region.
Parviainen emphasises that the primary objective of the reform is to allocate the power-based tariff on the "user pays" principle to the new customers whose connections increase costs and the pressure for investments in the main grid.

Another proposed reform is the introduction of a flexible main grid service. The reformed model is intended for existing customers and new customers who can be flexible in pre-agreed circumstances. It would thereby support transmission management in the main grid.
