Soluna Acquires Full Ownership of Project Dorothy 1B, Completing Equity Consolidation of Dorothy 1 Campus

With the Briscoe Wind Farm providing 150 megawatts of owned renewable power and now 100% equity control of both D1A and D1B, Soluna has assembled the full generation-to-compute ownership chain of 50 MWs at Project Dorothy 1. This unencumbered ownership position is a prerequisite for converting the campus to AI and high-performance computing workloads, and for marketing Dorothy 3, the Company’s next-phase AI infrastructure development, to prospective customers.

“Completing the acquisition of Dorothy 1 is an important step in our broader roadmap toward building Dorothy 3 for AI and high-performance computing,” said John Belizaire, CEO of Soluna. “We can now decide when and how we convert, bring in the right partners on our terms, and present Dorothy 3 to AI customers as a fully controlled, powered campus.

Transaction Details

The Company is actively evaluating opportunities related to Dorothy 2 as part of its broader campus development strategy. Soluna’s development pipeline now exceeds 4.3 gigawatts, including more than 1 gigawatt of projects in development, construction, and operations.
