Fortum provides local hydropower to EcoDataCenter in Falun, Sweden

Fortum and Swedish digital infrastructure provider EcoDataCenter have signed a five-year power supply agreement for delivery of 10 MW capacity and Guarantees of Origin from Fortum’s nearby power plants in Dalälven. The agreement supports EcoDataCenter’s data center in Falun, where CoreWeave, the Essential Cloud for AI™, is establishing advanced compute capacity. The contract term started in January 2026 and runs until the end of 2030. In addition to the power supply agreement, Fortum assumes responsibility for the physical electricity supply and balance responsibility for EcoDataCenter’s operations in Falun.

The agreement ensures that a share of EcoDataCenter’s energy needs in Falun is now tied to local hydropower production. Both Fortum and EcoDataCenter have deep roots in the Dalarna region. Fortum owns, co-owns and operates 39 hydropower plants along the Dalälven river, forming the backbone of the region’s energy system. For EcoDataCenter, the Falun facility is the company’s first facility to be put into operation.

“Our strong roots in Dalarna and close collaboration with local power producers are key to growth – both for us and for the industry as a whole. The agreement with Fortum, which supplies our facility in Falun with power directly from the Dalälven river, is a good example of this. When data centers and energy companies plan together, natural solutions emerge that create new opportunities for the entire region,” says Peter Michelson, CEO of EcoDataCenter.

Fortum's strategic priorities are to deliver reliable energy to customers and drive decarbonisation in industries in the Nordics. The company’s power generation portfolio offers an optimal low-carbon energy mix to work together with the industrial customers to find solutions to lower their carbon footprint. Fortum sees significant opportunities in supporting the growing data centre sector with stable, fossil-free electricity.

“Data centers are an important and expanding industry in Sweden, and we at Fortum see great potential in this segment. This is an important first step in Sweden in a deliberate focus on this sector going forward. Being able to begin this journey in Dalarna, where we have such a strong local presence through our hydropower, is especially rewarding,” says Simon-Erik Ollus, Executive Vice President for Corporate Customers and Markets at Fortum.
