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.
Erno Paananen works on data exchange for Fingrid. He is employed in a specialist position that suits him perfectly.
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.
The energy sector and its key player, Fingrid, will facilitate the green transition as long as we play our cards right, according to Jukka Ruusunen, who will retire at the end of the year.
Electricity transmission must be suspended or restricted when parts
of the main grid and grid connections are built and renovated. Fingrid plans outages with its customers well in advance. Customers should keep their contact details up to date in the My Fingrid service to ensure effective communication of transmission outages.
The International Transmission Operations and Maintenance Study (ITOMS) evaluates the effectiveness
of maintenance among electricity transmission companies every two years. The study again ranked Fingrid among the top performers in terms of maintenance.
The frequency is an indicator of the balance between electricity consumption and production.
