The main grid’s formative years

Since 2010, Finland’s main grid has expanded more than ever before. The pace will accelerate further in the coming years. The Aurora Line transmission link is this decade’s most significant investment in the main grid.

Main grid fee reform to ease congestion in the grid

Fingrid is planning reforms to restructure the main grid fees and contribute
to improving the network’s adequacy during the transition of the power
system. The new model encourages a regional balance, easing congestion in
the transmission network.

Many balls in the air

Detailed planning and foresight are the key jobs of a project manager on a transmission line project. They must also be ready to respond swiftly to unexpected challenges.

Clean electricity is a competitive advantage

We updated our electricity production and consumption forecasts at the start of the year. Finland has highly promising opportunities for success in the energy transition. The number of enquiries for main grid connections from electricity producers and electricity-intensive industries has continued to climb. The main grid needs significant construction and development to enable investment.

The power system is expanding, driven by wind and solar power

The need for electricity will rise in Finland in the coming years. At the same time, fossil fuels are being phased out entirely. Therefore, wind and solar power must produce even more clean electricity. How can we ensure there is enough electricity on calm, cloudy days?

Working with the energy sector to maintain stability in a converter-dominated power system

The power system of Finland is undergoing a major change. It is increasingly dominated by power converters, as wind power is becoming the main form of electricity production and solar power is also increasing in importance. In recent years, Fingrid has been leading the development of methods to ensure the technical functionality of converter-dominated power systems in Finland and elsewhere in the Nordic region.

Out and about with a transmission lineman

A power lineman’s work does not end when the building of a transmission line is complete – it is just the start. Lines are inspected in the summer, and maintenance work takes place all year round.

Relay protection counters the adverse effects of disturbances

Finland’s main grid is one of Europe’s most reliable electricity transmitters. Nevertheless, faults and disturbances occur approximately 300 times a year. However, not all of them need to be repaired on-site, thanks to relay protection in the main grid.
