CleanSpark: Mountain City Data Center

CleanSpark Mountain City Data Center is a digital infrastructure facility located in Mountain City, Tennessee, supporting large-scale Bitcoin mining and high-density compute operations across the Appalachian region. The site expands CleanSpark’s Tennessee infrastructure footprint and strengthens the company’s presence within the Tennessee Valley Authority power network. The facility is positioned to support energy-intensive workloads that require scalable power delivery, resilient utility access, and room for future compute expansion.

The Mountain City location is designed around 30 MW of planned power capacity and occupies a large industrial parcel near Highway 421 in Johnson County. The project forms part of CleanSpark’s broader infrastructure strategy focused on deploying high-performance compute environments across energy-rich regions of the United States. The Tennessee deployment benefits from proximity to TVA generation assets and regional transmission infrastructure that supports continuous power availability for digital asset mining and future compute applications.

The facility is planned with immersion-cooling technology intended to support quieter operation and improved thermal efficiency compared to traditional fan-cooled mining environments. The site adds to CleanSpark’s broader Tennessee portfolio, which includes operational infrastructure across eastern Tennessee connected to TVA-served utilities. The Mountain City deployment also aligns with broader infrastructure growth initiatives tied to scalable AI and high-performance computing development announced by CleanSpark during 2025 and 2026.

Mountain City provides geographic advantages for digital infrastructure deployment due to its access to regional power distribution networks, rural land availability, and connectivity into broader southeastern United States fiber corridors. The location offers reach into Tennessee, North Carolina, and Virginia markets while remaining within a state increasingly targeted for energy-intensive compute infrastructure. The facility also supports economic redevelopment efforts in Johnson County following industrial closures in the region and contributes to the area’s transition toward next-generation digital infrastructure investment.
