Vattenfall is to supply renewable electricity to the supercomputer Lumi at CSC’s data centre in Kajaani, Finland, from the start of next year.
The data centre will receive up to 100 gigawatt-hours of guarantee of origin-certified hydropower a year.
CSC is a Finnish centre of expertise in information technology owned by the Finnish state and higher education institutions.
Vattenfall business sales, head of production clients Magnus Westberg said: “Vattenfall wants to enable a fossil-free living in one generation.
“To win this electricity supply agreement shows that we have a product and solutions that well matches the needs of our customers in Finland.
“CSC has high ambitions to be fossil free and new digital solutions and technology can in a smart way be used to enable that. I will personally also follow the exiting development of the supercomputer.”
CSC managing director Kimmo Koski said: “Supercomputers consume a lot of electricity, so the use of hydro power is important to reach climate goals.
“Besides the advantage of renewable energy we have excess heat from cooling water, thanks to which waste heat can be utilized in Kajaani’s district heating network.
“This reduces both costs and the carbon footprint. LUMI will be one of the world’s fastest supercomputers and will serve European research and innovation activities, strengthening the competitiveness of Europe and increasing its scientific potential.”
