CHEYENNE, Wyo. (AP) — An artificial intelligence data center that would use more electricity than every home in Wyoming combined before expanding to as much as five times that size will be built soon near Cheyenne, according to the city’s mayor.

“It’s a game changer. It’s huge,” Mayor Patrick Collins said Monday.

With cool weather — good for keeping computer temperatures down — and an abundance of inexpensive electricity from a top energy-producing state, Wyoming’s capital has become a hub of computing power.

The city has been home to Microsoft data centers since 2012. An $800 million data center announced last year by Facebook parent company Meta Platforms is nearing completion, Collins said.

The latest data center, a joint effort between regional energy infrastructure company Tallgrass and AI data center developer Crusoe, would begin at 1.8 gigawatts of electricity and be scalable to 10 gigawatts, according to a joint company statement.

A gigawatt can power as many as 1 million homes. But that’s more homes than Wyoming has people. The least populated state, Wyoming, has about 590,000 people.
