Google commits $17 billion to its first Wyoming data center campus

Google is putting $17 billion behind a single patch of southeastern Wyoming.

The company’s proposed campus, called Project Tembo, would sit in south Laramie County near Cheyenne. It would be Google’s first data center in the state, and the price tag lands it firmly in big-league infrastructure territory.

What Google plans to build

The campus would cover approximately 716 acres.

At its core are four large data center buildings. Together they total around 3.08 million square feet of space.

The plan also includes an office building, logistics and network facilities, and the supporting infrastructure a campus like this requires.

The headline technical figure is power. Project Tembo is designed around 2.7 GW of capacity, a figure that includes reserves.

Who keeps the lights on

Black Hills Corp. has committed $1.8 billion to new generation tied to the project.

The arrangement also includes a private microgrid that runs through 2048. A microgrid is a localized power system that can serve a specific customer, rather than drawing everything from the wider public grid.

A long runway to completion

Site work and mass grading could begin by late 2026. Vertical construction, meaning the buildings actually going up, is slated for 2027.

Initial operations are targeted for the second half of 2028. Full completion is expected in the first half of 2031.

From Project Jade to Project Tembo

The site did not start out as a Google project. It was originally known as Project Jade, a venture involving Crusoe and Tallgrass.

After Crusoe exited, Google took over as lead in mid-2026. It did so through an entity called Jupiter Star Holdings LLC.

What it means for Laramie County

Peak construction employment is expected to reach about 2,500 workers.

The campus is expected to become one of Laramie County’s largest future tax bases.
