Facebook is eyeing another expansion of its huge data center in North Fort Worth.
The first two buildings in the $1 billion project on State Highway 170 in the AllianceTexas development opened in 2017.
Since then, Facebook has quietly been adding to the 150-acre high-tech campus.
The buildings house the one of the largest concentration of computing power in the state.
Now Facebook has filed plans with the state for even more construction at the site.
The Fort Worth 4 Data Center project at 4500 Like Way includes more than 277,000 square feet of underground work and site utilities.
Chicago-based Sheehan Nagle Hartray Architects, which has handled other Facebook data centers, is designing the North Fort Worth project.
The construction isn’t set to be completed until 2022, according to the filings with the state.
Facebook’s data centers are the size of shopping malls, with buildings that house acres of computer servers and the equipment needed to keep them powered, cooled and running 24 hours a day.
North Texas is one of the country’s largest data center markets.
