Regular system testing and practical exercises with various parties ensure that Fingrid is ready to respond to a crisis. For example, communication is paramount in the event of a major operational disturbance.
Hoar frost sticks to the earth wires of transmission lines and presses them onto the phase conductors. The consequence is an earth fault, which de-energises the transmission line. If there is a very large amount of ice load, the tower structures or earth wires could break.
The power system is in the midst of an unprecedented transition, which calls for major investments in the main grid.
Fingrid’s safety theme for 2022 is “Occupational safety is created by individuals and teams”.
The key personnel in charge of contingency planning in Finland and Sweden attended a course Hanaholmen to consider and practise effective ways of combatting and resolving civil crises.
Fingrid is raising the fee for electricity transmission in the main grid by an average of two per cent in 2022.
Finland’s main grid has an excellent reliability of operation rating. There can be more than 350 disturbances per year, and faults are cleared swiftly. Mari Kiuru, Network Control Expert at Fingrid, answers our questions.
Fingrid takes care of building and dismantling parts of the main grid. It is important to maximise the proportion of materials that are put to new uses.
A development project due for completion in the summer was also supported by customer feedback groups. It is already possible to send connection enquiries using the map service on Fingrid’s website.
This decade, Fingrid will invest a record EUR 2 billion in electricity networks and substations on Finland’s main grid.
