Microsoft is focusing on the Nordic region for data centre expansion, prioritising renewable energy and stable infrastructure. It plans to build 12 data centres in Finland and partner with local utilities to reuse waste heat for sustainable operations.
Microsoft is adjusting its data centre strategy to prioritise power availability over user demand, focusing on the Nordic region for its potential to provide emission-free energy to support AI-driven growth, according to Alistair Speirs, Microsoft’s senior director for Datacenter & AI Infrastructure.
Microsoft, which operates around 300 data centres worldwide and plans to invest $80 billion in additional facilities by the end of June, aims to become carbon negative by 2030. To meet this goal, the company needs to secure renewable, emission-free power to sustain the increasing demand for AI-driven cloud services.
Speirs noted that the growing use of artificial intelligence is creating new workloads that are not restricted to specific locations by regulation. This flexibility allows Microsoft to build data centres in regions with reliable and renewable energy sources, such as the Nordic countries.
“There’ll be locations across the world but efficient energy infrastructure is going to be the deciding factor for a lot of these areas,” Speirs said during a visit to Finland.
Nordic region’s appeal for data centres
The Nordic region has become a prime location for data centre expansion due to its cold climate, stable power grids, and abundant renewable energy sources. These factors make it easier for companies to meet sustainability targets and lower operating costs.
- Cold climate: The naturally cold climate reduces the load on energy-intensive cooling systems. Facebook’s data centre in Luleå, Sweden, benefits for example by using the cold air to cool servers, lowering energy consumption.
- Stable power grids: Nordic countries have reliable electrical infrastructure, which ensures more consistent operations. Google’s data centre in Hamina, Finland, has benefited from this stability.
- Abundant renewable energy: The availability of wind, hydro, and solar power supports the transition to sustainable operations. Google’s Hamina data centre operates with 97% carbon-free energy and repurposes waste heat to provide heating to local communities.
Other companies are also investing in the Nordic region. XTX Markets, a London-based algorithmic trading firm, plans to invest over €1 billion in a data centre complex in Kajaani, Finland. The facility is expected to be operational by 2026 and will support high-frequency trading.
Finland’s strategy to attract tech investment
Finland has implemented policies to attract tech investment by leveraging its renewable energy resources and modernising infrastructure. To strengthen the country’s position as a data centre hub, the government is implementing a strategy that provides tax incentives and industry collaboration.
Microsoft is currently developing 12 new data centres on three sites in Finland. The company is working with local utility companies such as Fortum to capture and redistribute waste heat from the data centres to heat residential buildings.
Waste heat recovery to support carbon neutrality
Fortum plans to collect waste heat from two new Microsoft data centre sites in the Helsinki region. The heat will be redirected to the district heating network, helping Fortum to reduce emissions and get closer to its target of achieving carbon neutral in its district heating operations in Finland by 2029.
Microsoft’s growing AI infrastructure requires significant computing power, which raises overall energy consumption. By integrating renewable energy sources and finding ways to utilise waste heat, the company aims to meet its sustainability goals and support the rising demand for AI-driven services.
Microsoft’s strategy for data centre expansion has evolved over the years. Initially, the company focused on building data centres based on user demand. This has shifted to creating supply in anticipation of future growth. The current “power-first” approach prioritises securing affordable and emission-free energy as the key elements in new data centre investments.
