atNorth, a Nordic data center operator known for high-density, renewable-powered facilities and integrated heat-reuse schemes, is expanding again in Sweden—signaling continued momentum for energy-efficient data center construction in Northern Europe. The company announced plans to build a new 30 MW data center in Stockholm, reinforcing the region’s role as a preferred location for AI-ready digital infrastructure tied closely to local energy systems.
The new site, SWE02, will be a metro-scale campus located near atNorth’s existing SWE01 facility in the Kista area, enabling customers to deploy seamlessly connected clusters across both locations. Designed with heat-reuse capabilities, SWE02 will recover excess heat and supply it to Stockholm’s district heating network in collaboration with Stockholm Exergi. The architecture also allows customers to separate workloads across campuses, improving redundancy and operational resilience.
The expansion includes a new electrical substation to be built by Ellevio, strengthening grid resilience for the surrounding area. SWE02 is scheduled to go live in Q4 2027 and follows a series of recent atNorth announcements, including campus expansions in Iceland, land acquisition for a future mega site in Sollefteå, and new heat-reuse and colocation partnerships across the Nordics.

- Design enables seamless cluster operations and workload separation across sites
- Integrated heat reuse through partnership with Stockholm Exergi
- New electrical substation to improve local grid resilience
- Targeted service launch in Q4 2027
“We are delighted that atNorth has chosen the Kista area for an additional energy efficient data center campus that will contribute to the city’s climate efforts,” said Karin Wanngård, Mayor of Stockholm. “The development and subsequent operational phase of this data center will bring employment opportunities for our community and further position Stockholm as a hub for digital infrastructure excellence.”
🌐 Analysis
The SWE02 project highlights how data center growth in Europe is increasingly linked to energy efficiency, grid integration, and heat-reuse rather than standalone capacity expansion. Nordic markets, in particular, continue to attract investment as operators like atNorth align AI-scale infrastructure with renewable power, district heating, and municipal partnerships, creating a model that contrasts with power-constrained regions elsewhere in Europe.
