Data Centers in San Antonio, TX
San Antonio is a major enterprise and government data center market, anchored by Rackspace Technology's global headquarters and Microsoft Azure's South Central US region. The city's large military presence — Joint Base San Antonio is the largest military installation in the US — drives substantial federal and defense-related data center and secure facility demand. CPS Energy's competitive commercial power rates and San Antonio's geographic centrality within Texas make it an attractive alternative to Dallas for Texas data center deployments.

FAQs
How does San Antonio's military presence affect data center MEP engineering requirements?
Joint Base San Antonio's three installations (Lackland AFB, Randolph AFB, Fort Sam Houston) generate demand for secure and classified facility construction — including SCIFs (Sensitive Compartmented Information Facilities) and command and control facilities — that impose MEP engineering requirements beyond standard commercial data centers. SCIF construction requires MEP systems to meet TEMPEST standards (preventing electromagnetic emanation), controlled ventilation with intrusion detection on all penetrations, independent power systems with no shared utility paths, and red/black electrical separation. Torch engineers MEP systems for San Antonio DoD facilities in compliance with DoD UFC (Unified Facilities Criteria) standards, which govern mechanical, electrical, and structural design for military construction.
What makes CPS Energy a favorable utility for San Antonio data center projects?
CPS Energy — San Antonio's municipal utility — offers several advantages over ERCOT investor-owned utilities for data center customers. As a municipal utility, CPS Energy is not subject to the spot market price volatility that caused the 2021 Texas power crisis — CPS maintains its own generating reserves and can negotiate long-term fixed-rate power contracts with large commercial customers. CPS Energy also has a dedicated large-load team for data center interconnection, with streamlined processes for multi-megawatt service requests. San Antonio data centers can structure their power contracts with CPS to include green tariff options, allowing renewable energy commitments without third-party PPAs.
