Soluna Powers Up Project Dorothy 2, to Increase Bitcoin Hosting Capacity by 60% to 123 MW

Soluna Holdings, Inc. (“Soluna” or the “Company”), (NASDAQ: SLNH), a developer of green data centers for AI and other intensive computing, announced that it has the approval from ERCOT and has successfully begun the initial energizing and phased commissioning of Project Dorothy 2, marking a significant expansion of its Bitcoin Hosting capacity.

The energization of Project Dorothy 2 represents the next phase of Soluna’s flagship Texas-based data center, designed to integrate seamlessly with renewable energy sources. The initial energization for the first 18 MW will be fully ramped in Q2 2025 and the remaining two phases totaling 30 MW will be completed by Q4 2025.

Summary Facts on Project Dorothy 2:

Total Size: 48 MW
Phases: 3 phases at 18, 14, and 16 MW each
Date of Initial Energization: Q1 2025
Anticipated Annual Revenue: $19 - $25mm
Estimated Date of Completion: Q4 2025
Revenue source: Bitcoin Hosting
Hashrate Capacity: 2.2 EH/s
Primary power source: Wind
Location: Silverton, Texas

The facility is connected to a 150 MW wind farm, providing a scalable solution to reduce curtailment and optimize clean energy usage. This new phase brings additional computing capacity online, reinforcing Soluna’s commitment to powering high-performance computing with sustainable energy.

John Belizaire, CEO of Soluna stated, “The energization of Project Dorothy 2 builds on the success of Project Dorothy 1, demonstrating how Soluna’s approach to curtailment solutions and sustainable computing can be scaled efficiently.” He added, “As we expand our Bitcoin Hosting capacity, we continue to attract the industry’s top Hyperscaler miners with our white glove service model called Relentless Stewardship.”

Key Features of Project Dorothy 2:

• Additional 48 MW of renewable-powered Bitcoin Hosting brings Soluna’s total capacity to 123 MW.
• Strategic integration with local energy infrastructure to minimize curtailment
• Optimized efficiency to support Bitcoin mining workloads with reduced environmental impact
• Demonstrates capability to scale data center facilities to material, 100MW+, size cost-effectively and efficiently

Soluna continues its tradition of naming its data centers after women scientists who help catalyze major innovation. Project Dorothy is named after Dorothy Vaughan, an African American mathematician and “human computer” who worked for the National Advisory Committee for Aeronautics and NASA in 1939, exemplifying innovation and excellence in computing.
