Data centers continue to crop up across the Westside of San Antonio and Bexar County, facing increased concern from residents and local officials alike. With the latest nearly half-billion-dollar addition to a data center hub on the Far Westside, projects filed on the Bexar-Medina county line have surpassed the $1 billion mark. Though, there’s even more infrastructure inside the city limits.
Vantage Data Centers has been a big driver behind these behemoth buildings moving in near growing residential areas. In the latest, the company – which boasts 41 campuses across five continents and 26 markets – is breaking its infrastructure investment record in Bexar County with a whopping $448 million, 174,000-squer foot campus on Omicron Drive.
“TX12 Open Fit-up includes the tenant build out of 96MW of data modules and all associated office and storage areas,” a filing with the Texas Department of Licensing and Regulation states. Vantage has been named one of the Top 10 fastest growing data center companies by Data Centre Magazine.

Already, more than $1.5 billion worth of data centers have been filed along Omicron and Lambda drives on the Far Westside – a pair of roads that form what is quickly becoming a sort of loop of massive data centers. Vantage has been the biggest builder by far, but Microsoft and CyrusOne have also shelled out hundreds of millions of dollars in this makeshift loop of energy and water hungry facilities.

Inside the city limits of San Antonio, a drive down Rogers Road feels daunting as mysterious, gated and windowless giant walls of concrete stare at you from either side. It’s here where another $735 million has been split between Vantage and Microsoft data centers in another burgeoning tech backbone in Bexar County.
These frequent additions are the source of rising concern and questions for folks in San Antonio. Omicron and Lambda drives are tucked away just off Highway 211 in an area seeing explosive residential growth in the past decade. While water and energy strain from these sites, which have largely popped up in just the past five years or so, remains unclear, folks are worried about somewhat rural stretches of Texas where water supplies are of frequence concern.

Some residents in this particular area living not far from the data centers reported power outages after the centers began to multiply. Though there’s been no clear correlation between the two reported.
Houston Advanced Research and the University of Houston Energy found a mid-sized centers sucks up 300,000 gallons of water per day. That’s supposed to mean water usage by data centers will increase ninefold across Texas by 2030. With so many moving into San Antonio and Bexar County, questions remain about the local impact.
When it comes to this data center boom within the city limits, San Antonio District 6 Councilman is asking for more transparency and planned policy to keep up with this boom.
“Our city cannot afford to wait until resource demands outpace our infrastructure,” Galvan said in a public statement, calling for a meeting of the minds among City Council, CPS Energy and San Antonio Water System leadership planned sometime after February 11. “As the Councilmember of the district with the largest number of data centers, my residents have expressed firsthand feedback on data center growth that deserves conversation at City Hall about proactive planning-not just for District 6 residents but for all of San Antonio.”
