AWS Nuclear-Powered Campus: 960MW Texas Hyperscale Hub
Status: Pre-construction / Site Mobilization (Announced 2026) | Location: Adjacent to Comanche Peak Nuclear Power Plant, Somervell County, Texas
Project Overview
A premier multi-billion-dollar co-located infrastructure initiative, this next-generation hyperscale data center development leverages behind-the-meter nuclear power integration to redefine how energy-intensive AI facilities are powered. Strategically positioned adjacent to a multi-unit nuclear generating station, the campus gains direct access to reliable, carbon-free baseload electricity without relying on conventional regional transmission infrastructure. By bypassing traditional ERCOT interconnection queues and transmission bottlenecks, the project significantly accelerates deployment timelines while ensuring uninterrupted power availability for high-density computing environments. The facility is purpose-built to support the immense energy demands of frontier artificial intelligence, including large language model (LLM) training, generative AI, scientific simulations, and advanced machine learning workloads that require continuous, high-performance computing. Its infrastructure incorporates scalable power distribution, liquid cooling systems, and modular expansion capabilities designed to accommodate future generations of GPU clusters and increasingly power-dense server racks. The direct integration of nuclear energy not only enhances operational reliability but also aligns with long-term sustainability objectives by delivering consistent, zero-carbon electricity around the clock. Beyond its technological advantages, the development establishes a new benchmark for energy-resilient hyperscale infrastructure, demonstrating how co-locating AI data centers with dedicated clean energy sources can overcome grid constraints while supporting the rapid expansion of AI computing capacity. This innovative model is expected to influence future hyperscale developments seeking secure, scalable, and environmentally responsible power solutions for next-generation digital infrastructure.
