The Microsoft Castroville Hwy 90 Campus, located at 2995 US Highway 90 West in Castroville, Texas, represents a major hyperscale cloud infrastructure development designed to support next-generation artificial intelligence workloads, Azure cloud services, and growing enterprise computing requirements. Situated in Medina County west of San Antonio, the multi-building campus spans more than one hundred acres and is engineered to provide scalable capacity, operational resilience, and long-term expansion potential. Its electrical infrastructure is supported by high-voltage utility substations connected to the ERCOT power grid, enabling substantial power delivery for energy-intensive computing environments. Mission-critical systems are further reinforced through static uninterruptible power supply architectures and dedicated standby emergency diesel generators with extensive fuel storage, helping maintain continuity during grid disruptions or other electrical events. The campus incorporates Microsoft's broader sustainability objectives, including efforts to reduce waste, improve resource efficiency, and support the company's carbon-negative ambitions. Advanced closed-loop cooling technologies are designed to minimize or eliminate water consumption during standard operations while accommodating high-density computing environments and emerging direct-to-chip liquid cooling configurations required for AI infrastructure. Connectivity is another key component of the development, with redundant subterranean dark fiber infrastructure providing resilient links to major Texas technology corridors and domestic fiber networks. Positioned within the expanding San Antonio technology market, the Castroville campus combines hyperscale computing capacity, resilient power systems, advanced cooling, and high-performance connectivity to support Microsoft's expanding cloud and AI infrastructure footprint across Texas and the wider North American digital ecosystem.
