Soluna Begins Energization of Project Kati 1, adding 83 MWs to Total Capacity

Milestone pushes available compute capacity beyond 200 MW

ALBANY, New York–(BUSINESS WIRE)–$SLNH #SLNH–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 that it has received ERCOT approval to begin the initial energizing and phased commissioning of Project Kati 1 on schedule.

Project Kati is Soluna’s 83 MW wind-powered data center campus in South Texas dedicated to Bitcoin mining. The energization will be split between Kati 1A, 48 MW, coming online in three phases and expected to be fully ramped by early Q2, and Kati 1B, 35 MW, following the three-phase approach and expected to be completed by the end of Q3. Kati 1B includes a 12 MW deployment with Cormint, where the company will design, procure, and deliver eight modular data center units to enable efficient deployment by minimizing on-site labor and accelerating energization timelines. Powered entirely by the Las Majadas wind energy project, Project Kati represents one of Soluna’s largest sites to date and is designed to scale efficiently to support large industrial compute workloads.

“This is a major milestone for project Kati 1, and a clear demonstration of our blueprint for Renewable Computing at scale,” said John Belizaire, CEO of Soluna. “Energization of this site represents an increase of more than 67 percent in our total capacity, expanding the number of customers we can serve with our signature Relentless Stewardship Bitcoin Hosting platform.”
