Soluna Holdings (NASDAQ: SLNH) builds modular data centers that are physically co-located at wind, solar, and hydro power plants, converting otherwise curtailed renewable electricity into computing power for Bitcoin mining, AI/HPC workloads, and its own “Soluna Cloud” GPU service. As of early 2026 the company operates or is bringing online sites in West Texas (Project Dorothy 1A, 1B, and 2, near a wind farm in ERCOT West), a hydro-powered facility in Murray, Kentucky (Project Sophie), and a large new campus in Willacy County, Texas (Project Kati 1, described by the company as its largest operational site to date, energized in early 2026). Soluna’s differentiator is its “behind-the-meter” model: rather than building near major metros, it sites facilities directly at renewable generation assets to soak up excess power, and it says its infrastructure supports high power density (over 60 kW, and up to 250 kW per rack in some configurations) for GPU, ASIC, and FPGA hosting alongside Bitcoin mining. The company has publicly discussed a growing pipeline — reported at over 1 GW in 2025 and around 6.3 GW by mid-2026 — spanning further Texas sites (Gladys, Fei, Rosa, Annie, Ellen, Hedy, Kati 2, Dorothy 3) in various stages of development.
Soluna operates as an AI cloud provider and colocation provider, with facilities at the following locations:
