Soluna Holdings (NASDAQ: SLNH) is a developer and operator of modular data centers that it co-locates directly at wind, solar, and hydro power plants, using its proprietary MaestroOS software to soak up otherwise-curtailed renewable electricity for Bitcoin mining, high-performance computing, and AI workloads. As of 2026 the company’s operating, under-construction, and shovel-ready site pipeline exceeds 1 GW and stretches toward a longer-term 2.8 GW development pipeline across roughly a dozen named projects in Texas and one in Kentucky. Rather than building conventional enterprise colocation halls, Soluna’s core differentiator is behind-the-meter integration: it buys excess power straight from a wind or solar farm (in some cases, as with Project Dorothy, actually owning the adjacent wind farm outright), letting it run flexible, batchable compute at very low energy cost while helping grid operators avoid curtailment. Alongside this hosting/colocation business for third-party Bitcoin miners, the company also runs a distinct subsidiary, Soluna Cloud, which sells dedicated NVIDIA H100 GPU capacity as an AI cloud service to enterprise and generative-AI customers such as SF Compute and Atlas Cloud.
Soluna operates as a AI-native cloud provider and colocation provider, with facilities at the following locations:

Soluna Data Center Locations
- Murray, Kentucky, USA Project Sophie PENDING REVIEW
Project Sophie, live since 2021, was Soluna's first greenfield project and introduced the company's modular 'diamond-site' design used across later Texas sites. - Paris, Texas, USA Project Annie PENDING REVIEW
Project Annie marked Soluna's first-ever solar-powered deployment and is named after Annie Easley, a pioneering NASA computer scientist and mathematician. - Rio Hondo, Texas, USA Project Ellen PENDING REVIEW
Project Ellen is named after Ellen Ochoa, the first Hispanic woman to travel to space, reflecting Soluna's practice of naming sites after pioneering women in science. - Silverton, Texas, USA Project Dorothy 1 (1A/1B)AI DATA CENTER PENDING REVIEW
Project Dorothy 1 has been reported to achieve a power usage effectiveness of 1.01, an unusually efficient figure for a modular, wind-powered site. - Willacy County / Rio Grande Valley region, Texas, USA Project Kati 1AI DATA CENTER PENDING REVIEW
Kati 1 became Soluna's largest operational site to date after energizing in early 2026, and drew an anchor customer relocating 48 MW of mining operations from its Texas Panhandle Helios campus.

AI Data Centers
Soluna's AI push centers on two distinct efforts: its physical campuses being converted or purpose-built for AI/HPC (like Project Kati 2, a 100+ MW AI and HPC campus in Willacy County co-developed with AI-infrastructure specialist Metrobloks, and Project Grace, a small 2 MW pilot explicitly designed for cloud and AI workloads), and its separate Soluna Cloud service, which deploys NVIDIA H100 SXM GPU clusters via an HPE GreenLake partnership and sells that capacity to AI customers like SF Compute and Atlas Cloud. The company has also said it plans to convert its original Dorothy campus in West Texas from primarily Bitcoin mining toward a vertically integrated AI-focused campus now that it owns the adjacent Briscoe Wind Farm outright.

Common Questions
Does Soluna sell AI/GPU compute directly to customers?
Yes. Through its Soluna Cloud subsidiary, the company deploys NVIDIA H100 SXM GPU clusters (via a partnership with Hewlett Packard Enterprise GreenLake) and sells dedicated capacity to customers such as SF Compute and Atlas Cloud for generative-AI and video-processing workloads.
Where are Soluna's data centers located?
Soluna's facilities are concentrated in Texas, including sites near Silverton, Rio Hondo, Paris, and Willacy County/Cameron County, plus one project (Sophie) in Murray, Kentucky.
Is Soluna a pure Bitcoin mining company or does it also do AI?
Soluna began as a renewable-energy Bitcoin hosting developer but has been repositioning several sites, such as Project Kati 2 and the Dorothy campus, toward AI and high-performance computing as demand shifts.
Does Soluna operate its own power generation?
In some cases yes — Soluna acquired the 150 MW Briscoe Wind Farm in West Texas for $53 million in 2026 to fully vertically integrate power supply with its Project Dorothy data center campus.
