Bitdeer Technologies and Soluna Holdings have struck a co-mining agreement to park roughly 28 megawatts of mining hardware at a wind-powered data center in South Texas. The deployment, slated to begin in September 2026, will add approximately 1.93 exahashes per second to the Bitcoin network’s hash rate, all powered by wind turbines spinning in Willacy County.
How the deal works
The arrangement splits responsibilities cleanly. Soluna provides the site, electricity, and day-to-day operations at its Project Kati 1 facility. Bitdeer brings the mining machines, specifically its Sealminer A2 Pro Air units, and retains ownership of the hardware. Both companies share the mining proceeds.
Deployment will happen in batches rather than all at once, ramping up from a September 2026 start date. Project Kati 1 is an 83 MW wind-powered data center, making the 28 MW addition a meaningful expansion of its utilized capacity without maxing out the site.
For Soluna, the timing is convenient. Project Kati 1 recently posted its first gross profit in the second quarter of 2026, a milestone for a facility that had been operating in the red while scaling up. Adding a tenant like Bitdeer, which supplies its own equipment and shares revenue, is essentially a way to monetize spare capacity with minimal capital expenditure on Soluna’s end.
