Sweden's biggest new data centers are going up in the north and in Dalarna, where power from hydro and wind is plentiful. In Långsele, in Sollefteå municipality, atNorth plans a 300-megawatt campus called SWE04 on the Hamre industrial park and signed a 200-megawatt grid connection with E.ON in May 2026. It needs an environmental permit for backup generators with 1,200 megawatts of installed capacity, and atNorth intends to apply to the Land and Environment Court in autumn 2026.
In Borlänge, EcoDataCenter is building on the site of the old Kvarnsveden paper mill, with the first data center due in early 2027 and 400 to 500 construction workers. In September 2026 it agreed to buy 52 hectares in Smedjebacken for a third Dalarna campus of up to 150 megawatts; permits are expected in early 2027. In Sandviken, Microsoft can restart two paused server halls at Tuna after the old Rörberg airport, which blocked a new power line, was ordered closed in March 2026.
The local argument is about electricity. Sollefteå Green Party politicians have written that atNorth's campus and a planned project near Ramsele would tie up about two-thirds of the municipality's wind power. Nationally, data centers account for almost 7,000 megawatts of the roughly 25,000 megawatts waiting to connect to the grid, and Prime Minister Ulf Kristersson confirmed in August 2026 that the government is working on a national data center strategy. Sweden ended its electricity tax break for data centers on July 1, 2023.
