Espoo sold land in Hepokorpi to Microsoft for data centre project

The City of Espoo has sold approximately 21.6 hectares of land in Hepokorvenkallio in Högnäs to Microsoft 3465 Finland Oy for the building of a data centre.

Microsoft will build a data centre in the area, and Fortum will use the waste heat produced by the centre for district heating. Fortum will distribute the waste heat generated by the cooling of Servers via the district heating system.

Espoo aims to achieve carbon neutrality by 2030. Based on a climate impact assessment, the Hepokorpi data centre project plays a key role in achieving this goal. Fortum is committed to producing carbon-neutral district heating in Espoo by 2029.

In the data centre computers, electricity transforms into heat, which can be used for heating buildings through the district heating network. In urban areas, the utilisation of waste heat from a data centre is one of the most ecological ways of producing carbon-neutral energy for the district heating network.

Microsoft also plans to build data centres in Kirkkonummi and Vihti. Fortum will recycle waste heat from data centres in Espoo and Kirkkonummi into district heating in Espoo, Kauniainen and Kirkkonummi. Once the data centres operate at full capacity, the carbon dioxide-free waste heat they generate will cover around 40 per cent of the heat needed by the approximately 250,000 users of district heating in Espoo, Kauniainen and Kirkkonummi.

The data centre will be built in Hepokorpi along Ring III.
