Google Horndal: New 150MW Air-Cooled Sweden Data Center
Status: Groundbreaking Achieved / Active Civil Construction (June 2, 2026) | Location: Greenfield industrial zone, Horndal, Avesta Municipality, Dalarna County, Sweden
Project Overview
The official June 2, 2026, groundbreaking of Google’s hyperscale data center campus in Horndal, Sweden, showcases the evolving design priorities of the European digital infrastructure sector. As regulatory scrutiny and resource limitations tighten across mainland Europe, hyperscale operators are expanding into the Nordics to capture abundant renewable energy while building more community-integrated facilities. Located within the Avesta Municipality, this new facility is engineered to support the next era of cloud computing and generative AI workloads across Northern Europe, integrating directly into the local physical and social landscape. From a technical standpoint, the Horndal facility sets a progressive milestone for resource-conscious engineering. Moving away from standard evaporative systems that pull heavily from local municipal water systems, the campus utilizes a 100% waterless, air-cooled design framework. This strategy limits water consumption strictly to basic sanitary and domestic building needs. To maximize efficiency, the facility features advanced off-site heat recovery infrastructure. This allows the server halls to capture excess thermal energy and route it free of charge to local eligible district heating partners, feeding clean warmth directly into Swedish homes and businesses while minimizing the facility’s overall carbon footprint. The project also provides an immediate economic lift to the region, utilizing more than 60 Swedish suppliers for its early construction phases. Beyond generating 100 permanent technical roles and thousands of secondary construction jobs, Google is funding regional digital literacy. This includes a €5 million local initiative fund alongside a Google.org grant backing AI Sweden to deliver comprehensive artificial intelligence skills training to 13,000 workers across Northern Europe. By balancing an efficient 150 MW design with zero-water cooling and aggressive heat reuse, Google's Horndal campus establishes a sustainable model for the modern AI economy.
