Maintenance of substations in the main grid requires various inspection, maintenance and preventive measures. Fingrid is supported by commissioning engineers, one of whom is Helsinki-based Valtteri Laine.
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.
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.
Fingrid’s main grid comprises more
than 14,000 kilometres of transmission lines. When the lines undergo maintenance, Fingrid strives to preserve natural values. In some cases, it is even beneficial to biodiversity.
Transmission outages are a necessary part of the construction and maintenance of the electricity network. Outages should be planned with care to ensure the
security of the energy supply.
