The projects are located in Västernorrland and Jämtland counties in northern Sweden. Work is scheduled to begin in November 2026, with both projects expected to be completed in 2029. 

The two contracts strengthen Enersense's position in the Swedish high-voltage market and highlight its expertise in delivering complex electricity infrastructure projects.

New power lines to support major data centre development in Sweden 

The first project involves the construction of two new 130 kV overhead power lines, each around 2.5 kilometres long, between the Hamre and Nässe substations in Sollefteå Municipality. 

The work includes installing 35 new steel lattice towers, removing around 2.5 kilometres of an existing power line and modifying the existing infrastructure near Nässe substation. The project is scheduled for completion in March 2029. 

The new power lines will strengthen the regional electricity network and help provide the infrastructure needed for atNorth's planned 300 MW data centre campus at Hamre Industrial Park. The project highlights the importance of reliable electricity infrastructure in supporting large-scale digital investments. 

Modernising an important power line in Jämtland 

The second project involves the reconstruction of around 12.6 kilometres of an existing 130 kV overhead power line between Hoting and Flybäcken in Strömsund Municipality. 

Enersense will be responsible for both the design and construction work. The project includes removing the existing power line structures and replacing them with an estimated 73 new support structures, including 71 wooden pole structures and two lattice towers.

As the power line serves several hydropower plants, construction will require careful planning. Work involving planned power outages will take place between April and September, with interruptions kept as short as possible to maintain a reliable electricity supply. 

Contracts have been recorded in the Power Business Unit’s order book for the fourth quarter of 2026.
