SOS Limited  announced that it is developing a next-generation Tier III modular data center at a Longfellow Ranch site in Fort Stockton, Texas. The project is intended to mark a significant strategic expansion for SOS as it transitions from a traditional cryptocurrency-mining operator to a full-scale digital-infrastructure provider.

Based on the conceptual design used in global large-scale data-center projects, SOS plans to deploy a prefabricated, modular Tier III platform that combines speed, efficiency, and scalability.

According to the design approach from the company, the modular data centers are designed to offer:

• Dramatically reduced construction timeline through pre-assembling
• Lower capital costs compared with conventional brick-and-mortar facilities
• Consistent quality, standardized components, and streamlined installation
• A greener and more energy-efficient layout with a reduced carbon footprint

These advantages allow SOS to build high-quality data-center capacity much faster and at materially lower cost. The company estimates that the modular approach may reduce total project cost by nearly 50%, lowering the expected investment from approximately $1.2 billion for a traditional build to around $500 million for a 100 MW data center.

The project will begin with a 10 MW modular data-center cluster. This first phase is designed to serve as a foundational building block for broader expansion. SOS anticipates scaling the Longfellow campus to as much as 100 MW within 18 months, depending on market demand and customer onboarding.

Longfellow Ranch is rapidly becoming one of Texas's most active centers for next-generation compute development. The area recently attracted industry attention after the announcement of a 2 GW AI data-center development involving CoreWeave and Poolside.

By deploying Tier III modular capacity in the same region, SOS is positioning itself to meet surging demand for secure, reliable, and rapidly deployable hosting services, particularly from AI, cloud, and enterprise customers seeking alternatives to traditional data-center markets.

"SOS is excited to take this important step toward becoming a leading provider of high-performance data-center infrastructure," Yandai Wang, the Chief Executive Officer of the Company commented. "The modular Tier III design gives us speed, flexibility, and cost efficiency as we grow, and Longfellow Ranch provides an ideal location for scaling into the expanding AI-compute market."
