Soluna Holdings, Inc. (NASDAQ: SLNH), a developer of green data centers for intensive computing applications including Bitcoin mining and AI, released its October 2025 project site-level operations, developments, and corporate updates.
The company announced a 3.3 MW hosting partnership with KULR Technology Group at Project Sophie, located in Texas. Agnes Budzyn was appointed to Soluna’s Board of Directors, contributing expertise in finance, digital assets, and technology. Soluna was featured in various publications, including The Texas Tribune and Data Center Dynamics, for its work in renewable computing. A new podcast with Generate Capital explored the impact of Soluna’s $100M credit facility on renewable-powered computing. Additionally, CTO Dip Patel participated in panels at the Climate Symposium at Harvard Business School and Infocast’s Energy Independence Summit, and moderated a discussion at IMN San Francisco, focusing on energy-efficient data center innovation and renewable-powered AI.
Project Dorothy 1A (25 MW, Bitcoin Hosting) continues to operate, benefiting from cooler temperatures that reduced curtailments and extended uptime. Preparations are underway for a 20 MW Canaan deployment in January, which will include next-generation Avalon A15 XP miners. At Project Dorothy 1B (25 MW, Bitcoin Prop-Mining), fleet upgrades and consolidation efforts are ongoing, with an additional 900 S19 XP miners expected to be deployed in early November, replacing the current S19J Pro fleet.
For Project Dorothy 2 (48 MW, Bitcoin Hosting), substantial completion of Phase 3 construction has been achieved, with overall construction expected to conclude by mid-November. The site is slated for full deployment, and hiring efforts are progressing in preparation for operational transition.
At Project Sophie (25 MW, Bitcoin Hosting), the deployment of one new 3.3 MW customer with upgraded units was completed by the end of October. A second new 3.3 MW customer with upgraded units is anticipated to be deployed at the beginning of November.
Project Kati 1 (83 MW Under Construction, Bitcoin Hosting) saw its substation upgrade completed for the full 83 MW. Civil and mechanical construction is accelerating, with the office and warehouse framing in progress. Installation of the Phase K1A 48 MW Galaxy is underway, involving the initial receipt and setting of containers, transformers, and switchgear. Long-lead electrical infrastructure to support Phase K1B 35 MW Soluna MDCs has been received on site and is staged for installation.
Project Kati 2 (83 MW Under Development, AI/HPC Hosting) includes a signed Memorandum of Understanding (MOU) with a development partner experienced in high-performance computing (HPC) to aid in the site’s development. Design and engineering are expected to commence in Q4. Site marketing and customer development efforts have begun. The substation upgrade for the full 83 MW has been completed, and initial long-lead equipment orders have been placed. Additionally, Soluna completed the land acquisition of 50 acres for this data center project, adjacent to Project Kati 1.
Project Grace (2 MW at Dorothy 2, Under Development, AI/HPC Hosting) has completed concept design for its microgrid electrical system, designed for AI load integration. An MOU was signed with a technology partner to develop a solution addressing power demand fluctuations caused by high-density AI loads, which can lead to grid instability.
In its pipeline, Soluna is finalizing Power Purchase Agreement (PPA) and Retail Electric Provider (REP) agreements for the Ellen and Hedy projects. Work on PPA agreements continues for projects Annie, Gladys, Rosa, and Fei. Regarding customer success, Soluna is completing the deployment of 48 MW across three new and expanding partnership agreements secured this year at Project Dorothy 2, and 7 MW across two new partnership agreements secured this year at Project Sophie. The company is also initiating the Project Kati 35 MW Hosting Request for Proposal (RFP) process with both current and new partners.
