Summary

Real estate company Castellum is partnering with energy technology firm Oilon to decarbonise the district heating network in Tampere, Finland.

Castellum will install some six heat pumps at the Valtatie 30 property to cool Nokia R&D vLab’s data centers.

The excess heat generated from cooling the data centers will be injected into Tampereen Sähkölaitos’ district heating network as renewable energy. The network provides heat to 6000 properties or 250,000 residents.

The six new heat pumps are expected to produce 50GWh of sustainable heat per annum as from 2022.

The pumps will heat water to the 95-degree temperature suitable for district heating, the water is then transferred to the main network and from there onwards to serve the needs of customers.

Pekka Leinonen, the head of B2B Sales & Customer Relationship at Tampereen Sähkölaitos, said: “That is about 2.5 percent of our heat requirements. The excess heat from the data center will be able to heat 50 apartment buildings per year, that’s a significant heat source for the district heating network.”
