AWS Pecos County Data Center Building B: Off-Grid Hyperscale AI Campus West Texas

Status: Under Development / Site Preparation (Permitted Off-Grid Infrastructure)   |   Location: GW Ranch Development Area, Pecos County (Permian Basin Region), Texas, United States

Project Overview

The AWS Pecos County Data Center (Building B) is a major compute block within Amazon’s planned off-grid hyperscale mega-campus in Pecos County, West Texas, designed to support the rapidly expanding infrastructure requirements of artificial intelligence, cloud computing, and high-performance workloads. Developed as part of Amazon Web Services’ strategy to secure large-scale, dedicated computing capacity, Building B is specifically designed to address the power availability challenges affecting major data center developments across Texas, including lengthy transmission interconnection queues and infrastructure constraints within the ERCOT market. Rather than relying entirely on conventional utility-grid connections, the facility is structured around dedicated behind-the-meter energy generation associated with the GW Ranch project site, providing a direct power architecture intended to support the enormous electricity requirements of hyperscale computing and next-generation AI infrastructure. This configuration can allow the campus to operate with greater control over its energy supply while reducing dependence on constrained regional transmission infrastructure. Building B is also engineered around the increasingly demanding thermal requirements of modern AI accelerators, incorporating custom liquid-cooling architectures designed for high-density computing environments. Advanced liquid cooling enables more effective heat removal from densely packed GPU and AI accelerator clusters than conventional air-based systems, supporting higher rack power densities and sustained computational performance. The facility forms part of a broader shift toward purpose-built AI data centers where electrical generation, cooling infrastructure, computing systems, and site design are developed as an integrated platform. Its location in West Texas also provides access to a large-scale energy ecosystem and expansive land resources suitable for hyperscale development. By combining dedicated behind-the-meter generation, off-grid-oriented infrastructure, advanced liquid cooling, and AI-focused compute architecture, AWS Pecos County Building B represents an emerging model for deploying massive data center capacity outside traditional grid-dependent development frameworks. The facility is positioned to support large-scale AI model training, cloud services, and other computationally intensive workloads requiring substantial power and high-density infrastructure.
