Soluna Fills Rack Capacity at Dorothy 2 with 30 MW Expansion with Top-Tier Bitcoin Miner

Soluna Holdings, Inc. (“Soluna” or the “Company”), (NASDAQ: SLNH), a developer of green data centers for intensive computing applications, including Bitcoin mining and AI, announced a 30 MW expansion with an industry-leading Bitcoin miner at the company’s flagship project site, Texas-based Project Dorothy 2. This marks the third expansion with this customer, who first deployed with Soluna at Project Sophie in 2023. With this deal, Project Dorothy 2 is now fully marketed and contracted.

“This milestone marks the full ramp of Dorothy 2’s sustainable hosting capacity—and another strong vote of confidence from one of our longest-standing customers,” said John Belizaire, CEO of Soluna. “It’s a major milestone in our growth pipeline, bringing 100% of our active facilities to full capacity. It also underscores the rising demand for efficient, renewable-powered infrastructure in the post-halving era.”

The customer expansion represents an additional 1,462.03 PH/s of hashrate powered by renewable energy, further advancing both companies’ commitment to sustainable blockchain infrastructure in the United States.

Project Dorothy 2 is a 48 MW data center co-located with a 150 MW wind farm. The first phase of its three-phase ramp came online in Q2 2025 and will reach full capacity in Q4 2025. The site is engineered to optimize Bitcoin mining efficiency while reducing environmental impact. Soluna will begin phasing in the customer’s hardware in the coming weeks.
