Project Dorothy Set to Energize in the First Quarter of 2023

Soluna Holdings, Inc. (“SHI” or the “Company”), (NASDAQ: SLNH), the parent company of Soluna Computing, Inc. (“SCI”), a developer of green data centers for Bitcoin mining and other intensive computing is providing the following corporate update.

The company’s Dorothy project, a 50MW facility in Texas continues to make steady progress through the regulatory process. The project is nearing the completion of the planning phase and will then advance into the modeling phase. The modeling phase is scheduled to complete in February when the project enters the operations phase where the logistics of a specific date for energization of the facility are set. This would put the project on track to begin energizing in the first quarter of 2023. The grid system operator, wind farm, and Soluna must coordinate physical logistics and other requirements as they drive to energize the site. Current target dates range from early February to early March as work is completed to integrate the facility with the grid.

Michael Toporek, CEO of Soluna Holdings, stated, “Through the market turbulence, we have remained focused to get Project Dorothy through the approval process. By working collaboratively with Texas regulators, the utilities, and the owner of the wind farm, we now have a clear path to energize the first 50MW of our Project Dorothy data center in Texas. We fundamentally believe Bitcoin and other intensive computing can be a major catalyst for the renewable energy industry, and this project will be a repeatable blueprint for future projects.”

Once the Company energizes Dorothy, anticipated to be one of the lowest cost facilities of its kind in North America, it will continue to refine the economic model of the first 50MW of this 100MW site. The table below updates a recent illustration of the earnings power of the site updated for current economic conditions, including current Bitcoin pricing and network hashrate.
