The Aurora Line, due for completion at the end of next year, will increase the electricity transmission capacity between Finland and Sweden by nearly 1,000 MW. It will significantly reinforce Finland’s power system and stabilise the electricity price.
Jaana Suontausta works with technology solutions and is passionate about solving
problems.
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.
Fingrid has employees scheduled for standby shifts, ready to respond to
phone calls at all hours of the day. Their task is to support the Main Grid Control Centre in the event of a disturbance.
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 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?
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.
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.
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.
