Soluna Expands Partnership With Blockware, Adding 6 MW at Project Dorothy 1

Deployment began in January and is expected to be completed by the end of February

ALBANY, N.Y.–(BUSINESS WIRE)–Soluna Holdings, Inc. (“Soluna” or the “Company”) (NASDAQ: SLNH), a developer of green data centers for intensive computing applications, including Bitcoin mining and AI, today announced the expansion of its partnership with Blockware, adding an additional six megawatts of capacity at Soluna’s Dorothy 1 site in west Texas.

This marks the third expansion of the partnership between Soluna and Blockware, reflecting the continued growth of Blockware’s operations and its commitment to scale alongside Soluna within an existing project. The expansion comes as a result of Soluna’s ability to support customer growth through flexible, capital-efficient infrastructure at renewable-powered sites. Deployment of the additional capacity began in January and is expected to be completed by the end of February.

“Repeat expansions like this are a strong signal that our model is working,” said John Belizaire, CEO of Soluna. “Blockware has continued to grow with us over time, and that kind of long-term alignment reflects the reliability of our infrastructure, our operational execution, and our ability to scale alongside customers as their needs evolve.”

The expansion builds on Soluna’s existing relationship with Blockware at Project Dorothy, where Soluna delivers behind-the-meter digital infrastructure designed to convert surplus renewable energy into productive computing. By expanding within an established site, Soluna can support customer growth efficiently while maintaining disciplined capital deployment.

“As we scale, maintaining strong uptime and operational reliability becomes increasingly important,” said Mason Jappa, CEO of Blockware. “We partner with teams that are singularly focused on delivering best-in-class data center operations. Soluna has consistently provided dependable infrastructure, rapid deployment, and a renewable-powered environment that supports long-term performance. That operational track record is why we continue to expand our partnership.”

Project Dorothy is part of Soluna’s 1 GW+ pipeline of renewable-first data centers designed to support high-performance computing workloads while helping stabilize the grid by utilizing energy that might otherwise be curtailed.
