Future Stockholm data centre will heat up 10,000 homes

Project is part of the Stockholm Data Centres Park initiative which aims to warm up 10% of Stockholm’s homes through data centre excess heat.

Sweden’s plans to become the energy efficient hotspot of the world have gained a new boost as a 5MW data centre is about to break ground in Stockholm where up to 10,000 homes will benefit from the facility’s wasted heat.

The company behind the project is Borderlight AB, a supplier of IT and Telecom services to the public and industry sectors, which has unveiled plans to install a large-scale heat reuse system that will be used to direct excess heat to residential apartments.

The operator has signed up local heating network provider Fortum Värme to absorb the excess heat into its network and then distribute it to households around the capital.

Fortum Värme’s district heating network connects more than 10,000 buildings, representing an aggregated heating demand of 12 TWh per year.

In addition, Borderlight’s sister company GoGreenHost will provide the server blades and racks specifically optimised for heat recovery, with rack densities reaching up to 100 kW per 19″ rack.

Sten Oscarsson, CEO of Borderlight and GoGreenHost AB, said: “Borderlight’s and GoGreenHost’s target is to become a leading supplier of advanced IT services coupled with efficient heat recovery from data centers that reach close to 100% recovery of consumed electrical power.

“Our plan is to contract installation of 30 MW in new data centre capacity 2017 and another 60 MW 2018 in sizes from 1 – 6 MW per site, all connected to a redundant high capacity fiber backbone.”

The new data centre development and consequent distribution of excess to thousands of households is included in the Stockholm Data Centres Park initiative launched in January 2017.

The project aims to supply 10% of Stockholm’s residential heating demand through recovered waste heat from data centres.

Close to 90% of all buildings in the Swedish capital are connected to the district heating network operated by Fortum Värme, which makes it easier for data centre operators and the heating network provider to collaborate and distribute the heat throughout the city.
