The presentation will introduce the aim and target for setting up a register for data centres in Germany. The Register to be built in 2022 will collect data especially on hyper scale and co-location datacentres but will be open for company or public data centres as well. The register will be developed as a blue print for a potential European Data Centre register. The register will contains data on energy performance and sustainability of data centres by regions within Germany on at least a NUTS-3 level basis
