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.
At the beginning of the year, Asta Sihvonen-Punkka stepped up from the positions of Executive Vice President and Senior Vice President of Electricity Markets to become the CEO of Fingrid. Her new work involves familiar topics, as well as learning new things and having to give up others.
“Advance preparations are made to handle the power system’s dimensioning fault. Sufficient reserves and electricity transmission management are the keys to this,” says Minna Laasonen, Development Manager at Fingrid.
When a new power plant connects to the main grid, it goes through several steps in the connection
process, guided by Fingrid’s Grid Code Specifications for Power Generating Facilities.
