Compute Nordic Ltd, a Norway-based data center developer and operator, has received formal approval of construction permits, and completed execution of power agreements, to develop 212 MW of IT compute capacity for the first phase of its AI Training and Inference Campus in Mikkeli, Finland. This achievement establishes the foundation for one of the most advanced, high-density data center developments in the Nordic region.
In a LinkedIn post Compute Nordic said that the Mikkeli campus has been designed from the outset to support extreme compute density and flexibility to focus on delivering scalable, energy-efficient infrastructure for next-generation compute workloads, including artificial intelligence, high-performance computing, and large-scale cloud platforms. The company says that its strategy centers on leveraging the Nordic region’s stable power grids, cold climate, and strong sustainability credentials.
Compute Nordic further says that the architecture of this upcoming facility incorporates dual-loop cooling systems engineered to support both direct liquid cooling (DLC) and rear door heat exchangers (RDHx), ensuring compatibility with the most demanding AI and GPU-based workloads.
Each data hall has a rack densities exceeding 240 kW per rack with a Power Usage Effectiveness (PUE) target below 1.15 for energy efficiency and operational sustainability. The data halls are configurable in terms of resilience and density to align infrastructure specifications with workload requirements and cost objectives.
With all required permits granted and power secured, the Mikkeli AI Campus now moves into the execution phase. The approved renderings show the structures authorized for construction and reflect the project’s readiness to proceed as the new year begins.
