Fingrid’s transmission line brochures for landowners have been updated. There were previously four brochures: two about the construction phase and two for the period after construction. As a result of the update, there are now two brochures.
The Imatra hydroelectric power plant began operating in 1929, along with the Imatra substation, which was the first substation on Finland’s main grid. The first transmission line on the main grid went from Imatra to Vyborg and onwards to Helsinki and Turku via Hikiä. In 2020, Fingrid commissioned a new substation in Imatra and began modernising the Imatra–Huutokoski transmission line.
The work to upgrade the Lake Line from Oulu to Lappeenranta to a 400-kilovolt transmission line began in the summer and autumn with the planning of environmental impact assessments (EIAs). The first projects to be assessed are the Vaala–Joroinen project and the Rovaniemi–Vaala project further north.
The Forest Line, which will be completed in 2022, is a transmission line connection between Petäjävesi in Central Finland and Muhos in North Ostrobothnia. The tree-clearing work, which began in autumn 2019, is a major job, requiring the removal of 60,000 cubic metres of material.
The electricity transmission main grid got its start in 1929, and this year it will celebrate an impressive 90 years of operation. We’re celebrating this anniversary in a working way; grid development continues because the need to transmit electricity will grow in the future as well.
