Meta’s geothermal ambitions are growing with a new agreement to support projects in New Mexico.

It announced the deal with XGS Energy today, a company developing next-generation geothermal technologies that make it possible to use this energy source in places where it was unfeasible before. The plan is to add 150 megawatts of carbon pollution-free electricity to the power grid that Meta’s data center plugs into in the region.

Meta desperately needs more electricity for AI. Power grids are trying to meet that growing demand from data centers. And those needs are buoying geothermal startups like XGS Energy.

“Advances in AI require continued energy to support infrastructure development,” Urvi Parekh, global head of energy at Meta, said in a press release. “With next-generation geothermal technologies like XGS ready for scale, geothermal can be a major player in supporting the advancement of technologies like AI as well as domestic data center development.”

Geothermal plants generate electricity using Earth’s heat; typically drawing up hot fluids or steam from natural reservoirs to turn turbines. That tactic is limited by natural geography, however, and the US gets around half a percent of its electricity from geothermal sources.

Startups including XGS are trying to change that by making geothermal energy more accessible. Last year, Meta made a separate 150MW deal with Sage Geosystems to develop new geothermal power plants. Sage is developing technologies to harness energy from hot, dry rock formations by drilling and pumping water underground, essentially creating artificial reservoirs. Google has its own partnership with another startup called Fervo developing similar technology.

Meta declined to say how much it’s spending on this deal with XGS Energy. The initiative will roll out in two phases with a goal of being operational by 2030.
