A $366 million data center project called Project Longhorn, Building One has been filed with the Texas Department of Licensing and Regulation for a site on Earl Callahan Road in Cedar Creek, Bastrop County. The facility will span 498,165 square feet, with construction slated to begin November 30, 2026, and complete by January 2028. At full buildout, the project is expected to deliver 710MW of site-rated redundant power from simple-cycle natural gas turbines, supporting 490MW of IT capacity. Representatives for Black Chamber, Pacifico Energy, and Anthropic did not respond to requests for comment, though Anthropic has been reported to be in talks to lease capacity at a major data center campus in the Cedar Creek area.
The filing proceeds despite Texas Governor Greg Abbott's September order halting new data center permits from the state's environmental agency pending an ERCOT grid audit, suggesting some projects are advancing through alternative regulatory pathways. The scale of 490MW of IT capacity at a single building, combined with a dedicated on-site gas generation plant, illustrates the degree to which large AI tenants are driving purpose-built power infrastructure rather than relying on grid connections.
A $366 million data center project tied to Anthropic, one of the most prominent AI companies, filing in Texas is a significant construction and AI infrastructure story. The Anthropic connection and large dollar figure elevate this above routine campus announcements.
