Infomaniak plans liquid-cooled data centre in Bulle that feeds district heating

Nov 13, 2026
The 170-rack site, due in 2028, will feed about 28 GWh of server heat a year into Gruyère Energie's district heating network.

Swiss cloud provider Infomaniak and local utility Gruyère Energie have filed plans for a data centre in Bulle, due in 2028, the companies announced. It will hold 170 server racks and use closed-loop liquid cooling for its compute and AI servers, so their heat can be reused more efficiently.

The site will run on renewable electricity and feed its waste heat into the regional district heating network, supplying about 28 GWh of heat a year. It is Infomaniak's largest infrastructure project, and the company plans to pay for it from its own cash flow as it serves demand for sovereign cloud and AI computing.
