Williamson County is at the center of one of the most significant data center buildouts in the United States. What started as a handful of projects near Samsung’s Taylor semiconductor fabrication plant has become a full-scale infrastructure rush.

According to a March 2026 Propmodo analysis using Cushman & Wakefield data, the Austin–San Antonio data center corridor now has 7,823 megawatts of planned capacity compared to just 1,154 megawatts currently operating. More than 70 projects are being tracked between Temple and San Antonio, with Williamson County capturing a disproportionate share due to its power infrastructure, fiber connectivity, and available land. Of the 615 megawatts under construction in the corridor, 96 percent is already pre-leased, a remarkable indicator of demand.

A Texas A&M Real Estate Research Center analysis found that between 2023 and 2024, Central Texas experienced a drastic increase in data center construction, totaling 463.5 megawatts of potential demand under development. That report specifically cited marquee projects in Williamson County as having reshaped regional land markets. Texas overall has 408 data centers listed statewide, second most in the nation, with the Austin market at 46 and climbing fast.
