Social media giant Meta has filed to develop a further 12 data center buildings on its El Paso, Texas, campus.

In a filing with the Texas Department of Licensing and Regulation, Meta subsidiary Wurldwide LLC has applied to develop 12 data center buildings under "Project Seafox" at 7001 Stan Roberts Sr in El Paso.

In addition to the data center buildings, Meta will establish five "owner substations" and develop around 600 acres of land, reports BLDUP. The total square footage of the new buildings will be 25.9 million sq ft (2.4 million sqm).

Stantec is the design firm behind the project. Works began in November 2025 and are expected to be completed by February 2029.

While the filing does not explicitly mention Meta, the company was revealed as being linked to Wurldwide LLC in late 2023 when it revealed plans for a 1,000-acre campus off of Stan Roberts Sr Avenue in El Paso. At the time, it was estimated that there could be up to five phases of development, with $800m invested in the first phase.

In October 2025, Meta announced it had broken ground on the data center campus and projected it would have 1GW of capacity. It also increased its estimated first-phase investment plan to $1.5bn. Each phase was previously expected to see 800,000 sq ft (74,320 sqm) of data center space developed, for a total of 4 million sq ft (371,610 sqm) of data center space. With the latest filing, this seems to have significantly increased.

In March 2026, this was scaled up again, with Meta saying it would invest $10 billion total in the campus. Some of the power for the campus will come from 813 modular gas generators, slated to come online by 2027, to power the site. This would total 366MW, and cost $473m.

Meta is designing the campus to support "both the traditional servers of today and future generations of AI-enabled hardware,” and will use a closed-loop, liquid-cooled system that will use zero water for the “majority of the year.”

The site was previously slated for a manufacturing facility.

El Paso, located in the west of Texas and close to the borders of Mexico and New Mexico, is not traditionally a major data center hub. Dallas, Austin, and sometimes Houston, all to the east of El Paso, are more popular with data center developers in Texas. Phoenix in Arizona, to the west of El Paso, is also a large data center market.

The campus will be Meta’s third in Texas. The company has data center campuses in Fort Worth and Temple in the Lone Star State. It also operates sites nearby in neighboring Los Lunas, New Mexico, and Mesa, Arizona.
