International assessments show that Fingrid has world-class main grid asset management. Properly timed and properly dimensioned investments keep the main grid in excellent operating condition. Investments of approximately 100–150 million euros are made each year.
Fingrid has had several transmission line worksites in progress this year. The next five projects – covering 600 kilometres of new transmission lines – are already in the final phase of planning. This is a sign of the need to renew and develop the main grid for future needs.
The Finnish main grid is a business accelerator; it helps to build new export assets for the future around clean electricity and open data. Finland has a rare situation on its hands: We are a pioneer in a technology for which there is an acute, global demand.
Fingrid’s innovation activity is primarily aiming for more efficient and higher-quality operations. Development work is being done in cooperation with experts from different sectors. Everyday examples of this are the Noiseless Acoustics sound camera and the NordSafety reporting system.
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.
