Where is Soluna’s Biggest Sustainable Data Centre to Date?
Soluna Holdings announces the start of construction on its largest facility to date.
Project Kati, located in Willacy County, Texas, is planned as a 166MW clean computing site.
A groundbreaking ceremony takes place for the wind-powered facility on 18 September 2025, bringing together partners, stakeholders and community leaders.
The project is built in partnership with EDF Renewables, Masdar and Spring Lane Capital.
It is designed to support both Bitcoin hosting and the fast-growing need for AI and high-performance computing (HPC) infrastructure.
“Breaking ground on our biggest project yet expands our Texas footprint, strengthens partnerships with leading renewable developers and proves our colocation model of pairing high-performance computing with clean energy at utility scale,” says John Belizaire, CEO of Soluna.
“Project Kati showcases our ability to deliver large-scale facilities with world-class investors and positions Soluna for long-term growth across Bitcoin hosting and AI infrastructure.”
Phased development strategy
Project Kati is structured as a two-phase buildout.
The first stage, known as Kati 1, focuses on Bitcoin hosting.
It will deliver 83MW of clean computing capacity – of which 48MW is allocated to Galaxy, a secured customer – and 35MW is reserved for Soluna’s own Bitcoin hosting operations.
Kati 1 is expected to go live in early 2026.
The second stage, Kati 2, is designed to add a further 83MW, taking the total site capacity to 166MW.
This expansion will allow the facility to accommodate AI and HPC workloads alongside Bitcoin hosting.
With this dual-purpose structure, the project aims to meet current demand while scaling for the next generation of computing requirements.
By phasing the buildout, Soluna intends to serve existing customers with near-term capacity while building a platform capable of supporting future applications such as machine learning and large-scale HPC.
Local impact and investment
The groundbreaking event highlights the role of Project Kati as both a data centre development and an economic driver for Willacy County.
With the backing of international renewable energy partners and investors, the project brings new jobs and local investment.
Soluna positions the facility as an example of its colocation model, in which computing infrastructure is integrated with renewable energy resources at scale.
This approach is designed to reduce environmental impact while delivering reliable power for intensive computing applications.
Scaling clean computing
Once completed, Project Kati will be Soluna’s largest site.
Its scale and design demonstrate the company’s strategy of aligning large-scale data centre operations with clean power sources.
The 166MW facility reflects the growing market for both Bitcoin hosting and AI infrastructure, as demand for computing capacity accelerates worldwide.
The development further strengthens Soluna’s Texas footprint, where renewable resources are abundant and grid connections support the expansion of energy-intensive industries such as digital asset mining and AI computing.
Project Kati’s dual-phase plan illustrates how Soluna adapts its operations to customer demand while keeping future expansion at the core of its strategy.
With construction underway, the company sets out to deliver both immediate capacity and a pathway to long-term growth in AI and HPC services.
