Under the main grid
The low rumble of an excavator breaks the silence of the riverbank at Tallikangas, in Vaala, Finland. Furrows one metre wide and half a metre deep criss-cross the field in a grid pattern, as excavation work enters its second day. The aim is to investigate whether the planned route for a 400 + 110 kilovolt transmission line runs through an archaeologically valuable area, perhaps containing remains of Stone-Age settlements.
Finland will begin to renew the main grid’s 110 kilovolt transmission lines in North Karelia next year. The wooden towers are more than 50 years old and aging. They will be replaced with sturdy steel towers, which can also withstand heavy hoarfrost loads in the winter.
The North Karelia main grid is located near Lake Pielinen. The Lieksanjoki River that flows into it and the Ala-Koitajoki River flowing into Pielisjoki River provide sites for landlocked salmon to reproduce naturally in Finland. Fingrid is one of the funders in the Saimaa landlocked salmon restoration project launched by the Ministry of Agriculture and Forestry.
Fingrid reacted quickly to Kemira’s plant expansion in Joutseno by renewing the main grid in Southern Karelia and building a new substation in the Joutseno area. This ensures that the growing need for power and electricity consumption can also be met in the future.
Modernisation of the Rautarouva (Iron Lady) line, which is the oldest section of Finland’s main grid, is nearing completion. Work to renew the 82-kilometre Koria-Ylilikkälä power line is currently in progress. The 110-kilovolt power line is being dismantled and replaced with a new 400-kilovolt line.
The majority of occupational accidents are caused by human or unconscious errors. This is why the attitude and commitment of employees is decisive in terms of how occupational safety is realised at worksites. This year, the emphasis in Fingrid’s occupational safety development is daily practices.
There are many ways for a landowner to utilise transmission line areas. Would you like some extra income from Christmas tree sales, or are environmentally friendly values close to your heart? Various land-use tips can be found in the new Landowner’s idea cards.
