Finland's transmission system operator (TSO) Fingrid Oyj, in cooperation with a Swedish TSO Svenska kraftnät, is preparing a new transmission line from Pyhänselkä in Muhos, Finland via Keminmaa, Finalnd to Messaure on the Swedish side of the border.

The new line will be the third 400-kV cross-border connection between Sweden and Finland which will is increase electricity transmission between the two countries, even out the price differences between the countries and improve sufficiency of the electricity supply.

The joint project of Fingrid and Svenska kraftnät has been included on the European Commission's list of Projects of Common Interest (PCI). According to the official decision, Fingrid Oyj is responsible for the investments in the project that will take place in Finland in full and for 80% of the transmission line investments on the Swedish side of the border.

"The new ac connection to Sweden is very important for the functioning of the electricity market. In 2019, the transmission capacity was inadequate as much as 40% of the time. This resulted in an increase in electricity prices in Finland," said Jussi Jyrinsalo, senior vice president, Fingrid.

The third ac connection to Sweden will be completed in 2025.
