For Huge Tech, there are few higher locations to experiment with information middle heating than within the Nordics. This concept works greatest when information facilities could be related to preexisting district heating techniques, the place a bunch of buildings share a standard heating system as a substitute of every having their very own. These communal techniques are commonplace in international locations like Denmark, Finland, and Sweden—and tech isn’t the primary business to experiment with connecting to them.
For the previous 20 years, Patrik Öhlund’s residence within the northern Swedish metropolis of Luleå has been partly heated by the waste warmth from a close-by metal plant. Now, Öhlund, who’s director of Power Markets at Microsoft, is engaged on recreating this technique within the Finnish metropolis of Espoo. However this time it’s Microsoft that’s being hooked as much as the native district heating community as a part of a undertaking that can finally warmth 100,000 households. As soon as accomplished, it’s anticipated to be the biggest information middle heating system on the planet.
Microsoft’s undertaking in Espoo will generate barely hotter water—90 levels Fahrenheit (32.2 levels Celsius)—than Meta’s Danish system, partly as a result of the Finnish information middle may also have the capability to energy AI techniques. Finnish power firm Fortum will then increase the warmth to between 180 and 250 levels Fahrenheit (82.2 and 121.1 levels Celsius), earlier than it enters folks’s properties—which ought to occur someday after 2025. Warmth extracted from information facilities that energy AI tends to be hotter as a result of they usually have a higher-density setup of server racks, says Tom Glover, head of knowledge middle transactions at actual property consultancy JLL. “You are supplied with the next high quality of warmth, which can be utilized higher inside district heating grids,” he provides.
When Microsoft’s Espoo system is switched on, power costs received’t essentially be cheaper, in line with Teemu Nieminen, who leads the information middle warmth restoration undertaking for Fortum. Neither firm will disclose how a lot Microsoft is charging for the warmth, however they do verify it’s a part of a industrial association. It may not be cheaper, however costs needs to be extra secure, says Nieminen, “in comparison with fossil fuels, the place costs fluctuate very wildly.”
Microsoft additionally hopes this stability will assist make information facilities on this scale extra welcome in native communities, a few of whom take difficulty with Huge Tech sucking up large quantities of renewable energy. “It’ll preserve the costs secure, and with folks dwelling close by understanding this … they’re additionally extra optimistic to our information facilities,” says Öhlund.
