For Big Tech, there are few higher locations to experiment with information middle heating than within the Nordics. This thought works finest when information facilities might be linked to preexisting district heating techniques, the place a gaggle of buildings share a typical heating system as an alternative 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 trade to experiment with connecting to them.
For the previous 20 years, Patrik Öhlund’s dwelling 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 Energy Markets at Microsoft, is engaged on recreating this technique within the Finnish metropolis of Espoo. But this time it’s Microsoft that’s being hooked as much as the native district heating community as a part of a mission that may ultimately warmth 100,000 households. Once accomplished, it’s anticipated to be the biggest information middle heating system on the planet.
Microsoft’s mission 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 even have the capability to energy AI techniques. Finnish vitality 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 individuals’s houses—which ought to occur someday after 2025. Heat extracted from information facilities that energy AI tends to be hotter as a result of they typically have a higher-density setup of server racks, says Tom Glover, head of information middle transactions at actual property consultancy JLL. “You’re provided with a higher quality of heat, which can be used better within district heating grids,” he provides.
When Microsoft’s Espoo system is switched on, vitality costs gained’t essentially be cheaper, in response to Teemu Nieminen, who leads the info middle warmth restoration mission 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 business association. It won’t be cheaper, however costs must be extra steady, says Nieminen, “compared to fossil fuels, where prices 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 challenge with Big Tech sucking up large quantities of renewable energy. “It will keep the prices stable, and with people living nearby knowing this … they are also more positive to our data centers,” says Öhlund.
