On Monday, Mayor Patrick Collins of Cheyenne, Wyoming, announced plans for an AI data center that would consume more electricity than all homes in the state combined, according to the Associated Press. The facility, a joint venture between energy infrastructure company Tallgrass and AI data center developer Crusoe, would start at 1.8 gigawatts and scale up to 10 gigawatts of power use.
The project's energy demands are difficult to overstate for Wyoming, the least populous US state. The initial 1.8-gigawatt phase, consuming 15.8 terawatt-hours (TWh) annually, is more than five times the electricity used by every household in the state combined. That figure represents 91 percent of the 17.3 TWh currently consumed by all of Wyoming's residential, commercial, and industrial sectors combined. At its full 10-gigawatt capacity, the proposed data center would consume 87.6 TWh of electricity annually—double the 43.2 TWh the entire state currently generates.
Because drawing this much power from the public grid is untenable, the project will rely on its own dedicated gas generation and renewable energy sources, according to Collins and company officials. However, this massive local demand for electricity—even if self-generated—represents a fundamental shift for a state that currently sends nearly 60 percent of its generated power to other states.
