STACK Infrastructure STO01 Stockholm Sovereign Data Center – 30 MW

Status: Fully Operational (STO01A) / Expansion Active (STO01B)   |   Location: Smedbyvägen 6, 194 30 Upplands Väsby, Stockholm, Sweden

Project Overview

The STACK Infrastructure Stockholm STO01 Campus (STO01A / STO01B) represents a major Nordic sovereign hyperscale data center development situated on a 4.5-hectare site in Upplands Väsby, Stockholm, Sweden. Benefiting from Sweden’s naturally cool climate and low-carbon electricity grid, the campus is planned to deliver approximately 30 MW of total critical IT capacity across 11,200 square meters of total white space. The STO01 development is designed to support the growing requirements of hyperscale cloud providers, enterprise customers, artificial intelligence platforms, and other high-density digital workloads while providing strategically located infrastructure within the Nordic region.

Designed for Hyperscale and AI Workloads

The STO01 campus is engineered to accommodate hyperscale cloud computing, artificial intelligence, high-performance computing, and enterprise workloads requiring scalable and reliable infrastructure. Its planned 30 MW critical IT capacity across the STO01A and STO01B facilities provides substantial room for high-density deployments and compute-intensive applications. The campus configuration is designed to support cloud platforms, AI training and inference, enterprise applications, and other data-intensive workloads while taking advantage of Sweden’s favorable environmental conditions for efficient data center operations.

Large-Scale Infrastructure and Economic Impact

The planned 30 MW critical IT capacity and 11,200 square meters of white space make STO01 a significant addition to Stockholm’s growing hyperscale data center market. The development expands the availability of large-scale digital infrastructure for cloud providers, enterprises, and AI-focused organizations seeking capacity within a low-carbon Nordic environment. Its location in Sweden supports the continued development of the country’s digital economy while strengthening Stockholm’s position as a regional destination for hyperscale computing, sovereign cloud infrastructure, and energy-intensive digital services. The campus also demonstrates the increasing importance of Nordic markets for customers seeking scalable infrastructure combined with access to lower-carbon electricity.

Strategic Connectivity and Nordic Infrastructure in Stockholm

Located in Upplands Väsby, within the Stockholm metropolitan area, the STO01 campus benefits from access to the region’s established telecommunications, fiber, power, and digital infrastructure networks. Its Stockholm location provides connectivity to major Scandinavian business and technology markets while enabling customers to serve users across Sweden and the wider Nordic region. The combination of a cool Nordic climate, low-carbon electricity grid, and strategically positioned metropolitan connectivity creates favorable conditions for efficient hyperscale operations. STO01 further strengthens STACK Infrastructure’s Nordic presence and reinforces Stockholm’s role as an important European hub for sovereign cloud, hyperscale, AI, and high-performance computing infrastructure.
