Soluna Holdings, a developer of renewable-powered green data centers, has announced a major expansion of its flagship project, Kati 1, in Texas following a deal with Galaxy Digital. The agreement will see Galaxy relocate proprietary data center operations from the Helios campus in Texas to a 48 MW extension of the Kati 1 site, bringing the facility’s capacity to 83 MW. Construction is slated to begin by end of August, with operations expected in Q1–Q2 2026.
Project Kati 1 Data Center Factsheet
Location: Texas, USA
Owner/Developer: Soluna Holdings
Partners: Galaxy Digital
Involved Financiers: Spring Lane Capital
Current Capacity: 35 MW
Expansion Size: 48 MW (increasing capacity from 35 MW to 83 MW)
Total Data Center Capacity: 166 MW
Soluna’s Total Fleet Capacity After Expansion: 206 MW
Power Source: Co-located Las Majadas Wind Project, Willacy County, Texas

Operations Start: Q1–Q2 2026
Grid Benefits: Monetize surplus energy, stabilize grid, maximize tax credit use
Connection to Las Majadas Wind Farm
Project Kati 1 is co-located with the 273 MW Las Majadas Wind Project, developed by EDF Renewables and Masdar, in Willacy County, Texas.
The wind farm has been faced with issues of grid congestion and low off-take from Electric Reliability Council of Texas (ERCOT), leading to wastage of green energy and resultant unclaimed tax incentives. Soluna’s data center, Project Kati 1, now helps come around this problem by taking up the surplus energy. Once operations start, Kati 1 will help stabilize the grid, unlock more tax credit revenue, and also open up investors’ revenue flow from the 273 MW Las Majadas Wind farm.
Project Kati Data Center: June 2025 Milestone
This green data center deal follows Soluna’s June 2025 milestone when the company received $20 million from Spring Lane Capital to finance the first 35 MW phase of Kati 1. The funds enabled the Research & Development (R&D) and build-out of an initial renewable-powered data facility, laying the groundwork for integration with high-performance compute workloads.
Additionally, with Galaxy on board, Project Kati 1 in Texas becomes Soluna’s largest single-partner deployment to date.

Why Project Kati 1 Matters
The data center, with full capacity of 166 MW, is out to kill two birds with one stone. It will support blockchain and AI workloads and also bolster Texas’ renewable energy economics.
