Renewable energy has shifted the focus of electricity production towards Northern Finland, and the new connection will transmit electricity efficiently to consumers. Reinforcing the transmission capacity between the north and the south also helps to ensure that Finland remains a single price area.
The project began in 2019 and was completed on schedule. It involved replacing old transmission lines and building a new 400-kilovolt transmission line connection requiring more than 800 transmission line towers. Substations were also built and modernised.
The connection runs from Petäjävesi to Oulu, and, with a length of 305 kilometres, it is the longest of Fingrid’s four main transmission lines.
