Amazon is moving to bulk up its San Antonio footprint with plans for a $65 million data center on the South Side, locking in another big cloud facility on the city’s fast-growing tech grid.
The company has filed plans for a 119,407-square-foot data center on a site along Donop Road, with construction targeted to start in late 2026. If it moves forward as outlined, the project would add yet another large-scale cloud hub to the city’s infrastructure buildout.
The application, submitted under Amazon Data Services, lists the 119,407-square-foot building and the roughly $65 million price tag, according to the San Antonio Business Journal. That report is the first public notice of the Donop Road filing and details the project’s proposed scale and timeline.
Industry mapping sites show Amazon is not exactly a stranger to Donop Road. DataCenterMap already lists an Amazon AWS presence at 12807 Donop Road. Local reporting has also followed Amazon’s steady land grab on the South Side in recent years, including multiple parcels near I-37 and Old Corpus Christi Road that helped establish the company’s footprint in the area.
Why the South Side
Developers and hyperscale operators favor the South Side for the basics: big, relatively affordable tracts of land and proximity to major transmission and utility corridors that can handle serious power and cooling demands.
Industry coverage has flagged San Antonio as one of the country’s rising data center markets. Bisnow points to large projects from Microsoft and others and cites market data showing that regional capacity has surged in recent years.
City And Utility Watch
The boom has City Hall and local utilities paying close attention. City officials are weighing new zoning tools and rules to keep data centers from landing too close to homes or parks and to help utilities manage the heavy, clustered demand that comes with them.
KSAT reported that, in discussions this month, SAWS and CPS Energy characterized the buildout as manageable so far but called for tighter oversight on where centers are sited and how much on-site power generation they bring with them.
The Donop Road filing adds another project to track as Amazon expands its local operations. The San Antonio Business Journal notes that construction could begin in late 2026, with permitting and utility coordination up next on the checklist. Hoodline will keep an eye on future permit filings and community notices and update this story as new documents or statements surface.
