• The 50 MW Data Center Clears the Modeling Phase in the ERCOT Process

ALBANY, N.Y. / Mar 14, 2024 / Business Wire / Soluna Holdings, Inc. (“SHI” or the “Company”), (NASDAQ: SLNH), a developer of green data centers for intensive computing applications including Bitcoin mining and AI, announced today Project Dorothy 2, its 50 MW data center co-located at a wind farm in Texas, has passed the modeling phase in the ERCOT Large Flexible Load approval process. Approval in ERCOT modeling is a significant step to begin the bidding process and finalize financing for this major expansion of the Company’s flagship project.

Bitcoin and AI Datacenters - Project Dorothy 2 will be the home of Soluna’s 48 MW Bitcoin Hosting expansion and its new 2 MW specialized AI data center, called Helix.

John Belizaire, CEO of Soluna Holdings, commented, “Through our experience successfully energizing our 50 MW first phase of Project Dorothy, we have a blueprint to bring Project Dorothy 2 online faster and more efficiently. Passing modeling allows us to now focus on building out Project Dorothy 2 for a mix of Renewable Computing applications, such as AI and Bitcoin mining.”

Compelling Financial Profile - Project Dorothy 2 is the second phase of Soluna’s flagship 100 MW data center, powered by renewable energy. It is expected to be one of the lowest-cost facilities of its kind in North America. According to the company’s financial modeling, Project Dorothy 2 has the potential to generate up to $14 million of additional annualized project-level operating profits¹ for the Company in Bitcoin Hosting revenue. The project forecasts an outstanding return on invested capital, returning capital invested in about 27 months.

Low Carbon Footprint - In late August 2023, the Company completed the construction and fully ramped Project Dorothy 1. A study done by a third party (REsurety) in early 2024 found the 50 MW site outperforms traditional data centers with an 18% lower carbon footprint while substantially reducing the burden on the electric power grid typically associated with traditional data centers. Project Dorothy 2 is on schedule to continue this trend of low carbon footprint data centers.

Shovel Ready - The next steps in the process for the new site includes completion of the construction bidding process including final construction costs for the first 48 MW, and finalizing financing options for the Bitcoin Hosting facility. To date, Soluna has received several proposals for financing Project Dorothy 2 and is close to completing diligence.
