What happened
Soluna Holdings and Bitdeer Technologies enlarged their Project Kati 1 co-hosting arrangement by approximately 7 MW, according to a statement first reported by NewsBTC on Tuesday. The expansion lifts Bitdeer's contracted power at the Texas facility to roughly 35 MW, translating into about 2. 42 EH/s of installed hashrate once the new machines come online.
Soluna said the extra tranche will be energized by November and fully books the K1BC phase of the project, closing out available capacity in that build-out. The site is wind-powered, a design choice Soluna has leaned on to pitch curtailment-linked economics to hosted miners. Neither company disclosed the fee structure for the expansion.
Why it matters
Hosting deals in the 5-10 MW range rarely move price, but they matter for the mining industry's plumbing. Bitdeer is one of a handful of publicly traded miners still adding hashrate aggressively after the April 2024 halving compressed block rewards, and each incremental megawatt shows where the sector's marginal capacity is landing. It's landing in Texas, next to renewable generation, at operators willing to absorb intermittency.
That's not a coincidence. Post-halving all-in costs for Bitcoin miners now sit uncomfortably close to spot, and cheap, curtailment-adjacent power is one of the few remaining edges. For Soluna, filling K1BC is a milestone that de-risks the phase's revenue base and clears the runway for the next build-out.
Market impact
Bitcoin's network hashrate has hovered near record levels through 2026, and small capacity adds like this one don't shift difficulty on their own. But the pattern is worth tracking. Publicly listed miners have been the swing bidders for hosted power all year, and Bitdeer's willingness to top up an existing site rather than wait for greenfield capacity says something about how tight the queue for energized racks has become.
