The transmission connections between Northern and Southern Finland were significantly strengthened in September with the commissioning of Fingrid’s Forest Line transmission link.
Fingrid, Helen Electricity Network, and the City of Helsinki are working closely together, as the need for
electricity transmission in Helsinki is expected to double in the next few years. The upcoming new 400-kilovolt cable link will contribute to the green transition and the realisation of the Western Boulevard City.
Fingrid is prepared for the event of electricity production disturbances.
In addition to buying from the balancing power market, it has access to approximately 1,200 megawatts of reserve power. Reserve power plants are always on standby, but the full 1,200 megawatts is very rarely needed.
Fingrid’s power system vision is based on various scenarios for the future, foreseeing transformational changes to the power system. The vision is now under further develop-
ment based on stakeholder feedback.
An electricity shortage occurs when electricity consumption momentarily exceeds the supply of electricity, and it becomes necessary to restrict
consumption. Fingrid, the distribution system operators, and the authorities have agreed on
what to do if an electricity shortage arises and how to get through it.
Managing the vegetation near transmission lines ensures electricity
safety and transmission reliability. Regular clearing also helps to maintain vital open habitats for certain animal and plant species.
The Baltic Countries are preparing to synchronize their electricity system with Continental Europe at the beginning of 2026. If Russia decides to disconnect them before this time, they can be connected to the Continental European grid within a few hours, in case of emergency.
Over the next ten years, Fingrid will invest a record EUR 3 billion in the main grid. This money will be used for the following purposes.
Finland’s internal transmission grid has two cross-sections, which Fingrid uses to monitor electricity transmission. In the future, several
times as much electricity will need to be transmitted over the cross-sections.
During the winter, it is very important that domestic production is available and the cross-border connections operate reliably.
