Risto Uusitalo, who supervises the work on the Forest Line transmission line worksite, spends his days meeting contractors and conducting site inspections in the field. Many of his colleagues are also familiar with Risto’s dog, Ilona, who sometimes accompanies him on-site. This is the first in a new series of articles about “Professional in the spotlight”.
The new control centre buildings are beginning to resemble family homes in terms of their technical building services and energy efficiency. The buildings are equipped with toilets, small kitchens, heating, ventilation and lighting.
Fingrid, Outokummun Energia and PKS Sähkönsiirto are together realising a solution for reducing the number of outages caused to customers on long main grid lines by more than half.
This summer, Fingrid will photograph transmission lines from the air. The company intends to photograph approximately 12,000 km of transmission lines – an unprecedented amount. The remainder of the transmission lines (just over 2,000 km) have already been photographed.

Congestion income provides Fingrid with hundreds of millions of euros for developing the main grid.
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.
LUT University is researching an entirely new solution to address the problem of carbon dioxide emissions due to heating. The university is developing a small nuclear power plant that will provide district heating. The minimum output of the district heat reactor must be 20–30 megawatts, and a few such units could satisfy the district heating needs of a medium-sized town.
Fingrid is working with Leppäkosken Sähkö to test a fuel cell solution that can charge the substation’s batteries, thereby safeguarding its critical functions in the event of a disturbance. Fuel cells generate energy from a mixture of water and methanol.
