Soluna and Metrobloks to Partner to Unlock 100+ MW of AI and HPC Capacity at Project Kati 2

Key Terms

ai technical

Artificial intelligence (AI) is technology that enables machines to mimic human thinking and learning, allowing them to analyze information, recognize patterns, and make decisions. For investors, AI matters because it can improve how businesses operate, create new products, or identify opportunities faster and more accurately than humans alone, potentially impacting company success and market trends.

high-performance compute (hpc) technical

High-performance computing (HPC) is the use of very powerful computers and specialized software to solve large, complex problems much faster than ordinary PCs, like using a construction crane instead of a hand cart to move heavy loads. Investors care because HPC enables faster product design, data analysis, and research across industries — driving competitive advantage, unlocking new revenue opportunities, and often requiring significant capital or recurring cloud spending that affects a company’s costs and growth prospects.

gpu-ready technical

GPU-ready describes hardware or software that is prepared to run tasks on graphics processing units (GPUs) instead of relying only on standard processors, with the necessary software and settings in place. Think of it like tuning a kitchen to use a high-power blender: workloads such as large-scale data processing, machine learning model training, graphic rendering, or certain compute-heavy services run much faster and more efficiently, which can lower costs, accelerate product development, and affect a company’s competitive edge—factors investors watch closely.

Co-development model combines secured power, AI-ready design, and rapid deployment for high-density workloads

ALBANY, N.Y.--(BUSINESS WIRE)-- 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 signed a Memorandum of Understanding (MOU) with Metrobloks, LLC (“Metrobloks”), a data center developer and operator focused on AI-ready infrastructure, to enter into a co-development partnership to build Project Kati 2 (aka MB MFE-A). The initial development will be a 100+ MW Critical IT (CIT) AI and high-performance compute (HPC) data center at Soluna’s Project Kati 2 campus in Willacy County, Texas. This is expected to be the first phase of a larger campus, with an expansion roadmap supporting more than 300 MW of total CIT capacity.

By combining Soluna’s renewable-powered campus and experience working with ERCOT’s reliable grid with Metrobloks’ AI-ready data center design, development, leasing, and operations platform, the venture aims to shorten time-to-market for customers who need dense, GPU-ready capacity and have struggled to find locations with both power and interconnection. Metrobloks specializes in high-density, sustainable data centers for AI and low-latency applications, with a leadership team that has enabled more than 12 gigawatts of global data center capacity. Located in South Texas near McAllen, Project Kati adds geographic diversity as a southern U.S. deployment option, supporting alternative siting strategies beyond Central and West Texas.

“Project Kati is our blueprint for Renewable Computing at scale, and this site reflects the kind of infrastructure AI now demands,” said John Belizaire, CEO of Soluna. “This site offers what AI and HPC deployments need most right now: available power, strong renewable resources, and a regulatory and grid environment that supports speed. Our team spent years securing the right location and power position at Kati. By partnering with Metrobloks to lead design, operations, and customer engagement for Kati 2, we can accelerate AI and HPC deployment while staying focused on what we do best, turning constrained renewable energy into productive compute.”

Soluna and Metrobloks intend to form a project company to own and operate Project Kati 2. Metrobloks will lead design, development, leasing, and day-to-day operations, including securing pre-lease commitments and managing customer engagement. Soluna will contribute site control, power entitlements, electrical equipment, and development expertise, while both parties will jointly source and structure third-party capital for the project. The site is currently under a (non-binding) letter of intent from a potential neocloud tenant. Looking ahead, the parties are working with EDF Power Solutions to source additional power from the Las Majadas wind farm to expand the project.

“Customers are telling us the same thing in every market. They need power and capacity now, not years from now,” said Ernest Popescu, CEO, Metrobloks. “Project Kati stands out because the power is both available and scalable. Soluna has already done the hard work to secure a renewable-powered site with room to grow. We’re building on that foundation with AI-ready design and a clear path for customers to scale high-density AI and HPC workloads beyond the initial 100 MW.”

Soluna broke ground on Project Kati in September 2025. The 166+ MW Texas wind-powered campus in Willacy County is being developed in two phases. The second phase, Kati 2, is designed to expand the campus with a dedicated 100 MW+ AI and HPC infrastructure in phase one, establishing Project Kati as a renewable-powered, dual-purpose facility that can serve both digital assets and AI or HPC customers as demand evolves.
