TelecityGroup expands its Suvilahti data center in Helsinki

We are in a hurry to share news about the upcoming expansion of the Suvilahti data center.

The completion of the next phase of construction, scheduled for October this year, will increase the data center capacity by 400 kW and the area for placing IT equipment by 200 sq.m. The total capacity of the data center will be 1.35 MW, and the total area of ​​machine rooms - 1050 sq.m.


Suvilahti data center is a kind of “working platform” for TelecityGroup Finland, a platform that has been functioning steadily since its commissioning in November 2011. A distinctive feature of the data center is the use of water from the Baltic Sea to cool server equipment. Finland, it should be noted, is one of the foremost in the use of sea water for cooling. The heat generated by the servers enters the Helsinki district heating system to heat nearby houses. This innovation provides energy efficiency benefits and PUE levels of less than 1.3 at full load. The unique design of Suvilahti was made possible thanks to the extensive Helsinki tunnel system, which houses the municipal infrastructure, and an extensive urban central heating and cooling system.

A high level of data center security is achieved due to perimeter fencing, external and internal video surveillance cameras, regular walk-arounds of the territory by the security service and access cards. Like our other data centers, Suvilahti has been certified for compliance with ISO 9001, ISO 14001, ISO 27001 and OHSAS 18001.
