The Data Center Boom Reshaping Williamson County, Texas

Williamson County, Texas, has emerged as a major hub for data center development, driven by factors such as existing power infrastructure initially built for Samsung's Taylor semiconductor plant, dense fiber corridors, and available land. According to a Propmodo analysis and Cushman & Wakefield data, the Austin–San Antonio corridor has 7,823 megawatts of planned capacity, with Williamson County securing a substantial share due to its strategic advantages and a pro-business environment promoted by the Williamson County Economic Development Partnership. The article highlights several key projects within the county. In Hutto, the Skybox Datacenters and Prologis Inc. campus on the Hutto Megasite is underway, designed for 600 megawatts, while Colovore received approval for a $500 million, 180,000-square-foot facility. Blueprint Data Centers has secured approvals for campuses in both Taylor and Georgetown, with an investment of up to $1 billion in Taylor. Sabey Data Centers and Switch are expanding their operations in Round Rock, with Sabey's facility attracting large liquid-cooling deployments like the Texas Advanced Computing Center’s Horizon supercomputer, and Switch planning over 1.5 million square feet of data center space. Amazon also has a planned unit development approved for a future data center in Round Rock. However, this rapid development has sparked community debate concerning water consumption, especially during recurring droughts, and the strain on the ERCOT power grid, which is projected to need to double its capacity by 2031. While newer facilities are mandated to use closed-loop cooling systems to mitigate water usage, and data centers contribute significantly to property taxes, critics note the relatively low number of permanent jobs created compared to the massive investments. Governance of data center approvals is decentralized, resting with individual cities rather than Williamson County itself, leading to a patchwork of policies and incentives. A lawsuit filed by Taylor residents against Blueprint's parent company over land use was dismissed by Judge Ryan Lawson, denying an injunction request. The expansion continues, with developers like Skybox proposing additional projects, some of which face ongoing resident concerns over noise and resource usage, underscoring the challenges of balancing economic growth with community impact.
