Data center developer Crusoe has paused work on Project Jade, a massive campus planned for Cheyenne, Wyoming.

The 1.8GW facility was announced last year, with claims it could scale to 10GW. Crusoe was working with Blackstone-backed energy company Tallgrass.

“At the request of our customer, Crusoe has paused its development activities," the company said in a statement. The company did not disclose the customer, nor why it requested the pause.

At the same time, Crusoe said that it has contracted 4.9GW of data center infrastructure for Crusoe Cloud. It claimed that its total development pipeline - including contracted projects, sites under active tenant negotiation, and sites in advanced development – exceeds 40GW.

The company's data center development portfolio contracted to hyperscale clients spans five AI data center campuses across the US.

Its flagship site in Abilene, Texas, was developed for Oracle and OpenAI but saw the customers pull out of the later stages due to delays. Microsoft ultimately picked up the remaining capacity at the site.

"The demand from the world's leading technology companies for AI infrastructure – quickly and at scale – has never been greater, and Crusoe is uniquely positioned to meet it," said Chase Lochmiller, co-founder and CEO of Crusoe.

"We work shoulder to shoulder with our customers to move from vision to operational infrastructure at the speed AI demands. The nearly five gigawatts under contract is a reflection of the trust our customers have placed in Crusoe, and that’s a responsibility we take seriously. We're building the AI factories of the future and making sure every AI builder – from the most innovative AI startups to the world’s largest hyperscalers and enterprises – has the infrastructure to match their ambitions."
