As of January 1, 2021, Vattenfall will deliver a yearly volume of up to 100 GWh of guarantee of origin-certified hydropower to CSCs data center in Kajaani in Finland. CSC is a Finnish center of expertise in information technology owned by the Finnish state and higher education institutions. As part of a pan-European initiative one of three leadership-class supercomputers, LUMI, will be located at CSC’s data center in Kajaani in Finland. LUMI is one of the fastest supercomputers in the world and will run on 100 percent fossil free hydro power from Vattenfall. In all service development and production, CSC strives to implement Finland's goal of being carbon neutral in 2035 and to promote the implementation of the European Green Growth Program. LUMI will be operational between 2021 and 2026.
The theoretical peak performance of LUMI will be over 200 petaflops. This, like the performance of applications on LUMI, is approximately ten times faster than with the Piz Daint supercomputer, which is the fastest in Europe at the moment.
