Soluna Holdings announced that its second‑phase data‑center, Project Dorothy 2, has been fully energized. The 48 MW facility brings the company’s total operational capacity to 123 MW, a 64 % jump from the 78 MW that were online before the launch. The new site delivers more than 5 EH/s of sustainable compute, maintains an uptime of 95 % and operates at an efficiency of 24 J/TH, while creating 18 full‑time local jobs.
The 123 MW figure represents Soluna’s entire energized portfolio, of which 100 MW are concentrated on the Dorothy campus (Project Dorothy 1A + 1B = 50 MW and Dorothy 2 = 48 MW). The 48 MW addition is the largest single expansion in the company’s history and represents a 73.3 % increase in capacity since the April 2025 launch of Dorothy 1. The campus now hosts the largest renewable‑powered high‑performance computing cluster in the United States.
Soluna’s strategy is to convert surplus wind energy into high‑performance computing for Bitcoin mining and AI workloads. The proprietary MaestroOS platform manages grid integration, monitoring and automation, enabling the company to achieve the 5 EH/s compute output while keeping power usage effectiveness at industry‑leading levels. The 95 % uptime and 24 J/TH efficiency metrics demonstrate the operational reliability that underpins Soluna’s green‑data‑center proposition.
Financially, Soluna’s Q3 2025 earnings were expected to be released on the same day. Analysts projected a negative EPS of $‑0.61 and revenue of $9.0 million, compared with a Q3 2024 EPS of $‑1.29. The company’s balance sheet shows negative equity and declining revenues, underscoring the challenges it faces despite the operational milestone. The earnings outlook reflects the company’s ongoing investment in renewable infrastructure and the need to balance capital expenditures with profitability.
The company’s pipeline now includes the 166 MW Project Kati, currently under construction, and future projects named Hedy, Ellen and Annie. Together, these developments position Soluna to scale its renewable‑powered computing footprint while creating additional local employment opportunities. The 18 jobs created by Dorothy 2 are part of a broader strategy to support the regional workforce and strengthen community ties.
CEO John Belizaire highlighted the disciplined execution that enabled the on‑time, on‑budget completion of Dorothy 2. He emphasized Soluna’s confidence in the green‑data‑center market and its commitment to cost discipline and strategic investments in high‑return verticals, signaling a focus on sustainable growth amid financial headwinds.
