A transmission line across Lake Kemijärvi connects the Nuolivaara wind farm to the national grid

The project involved the construction of a 32 km long 110 kV power line from Kellarijänkä substation to Nuolivaara wind farm in Kemijärvi. The power line crosses the Kemijoki River, so some of the electricity pylons were built on islands.

Building in a varied terrain required thorough planning and adaptability. In the winter, we built an ice road leading to the islands, along which equipment could be transferred safely across the water. The foundations for the electricity pylons were laid directly on the islands. The pylons were assembled on the mainland and transported to the installation sites on a raft. We used two boats to lift the pylons and a barge to transport the raft and equipment. Despite the challenging conditions, the island-based pylons were erected on schedule.

“The power line is an important part of the wind farm project. Despite the varied terrain, waterways and challenging conditions in the North, Destia carried out the project professionally and reliably,” says Olli-Pekka Jaako, Head of Wpd Construction Finland Oy.

The new power line has made it possible to build the entire wind farm on the territory of the city of Kemijärvi. The project created many new jobs in the area, and the wind farm itself will have a significant economic impact on the city.
