Soluna Holdings, Inc. (NASDAQ: SLNH) has amended its agreement with Dory Creek, LLC, a wholly owned subsidiary of Bitdeer Technologies Group (NASDAQ: BTDR), adding approximately 7 MW of Bitcoin mining capacity at Project Kati 1 in Willacy County, Texas.

The expansion brings Bitdeer's total deployment at the site to 35 MW and approximately 2.42 exahashes per second (EH/s) of hash rate. The addition fully subscribes the site's K1BC phase, according to a press release from Soluna. The expanded deployment is expected to be complete in November 2026.

Project Kati 1 is an 83 MW wind-powered data center. The arrangement is structured as a co-mining agreement, under which Soluna provides the site, power, and operations, while Bitdeer supplies and owns its Sealminer A2 Pro Air mining equipment. The two parties share in the mining proceeds generated by the deployment.

Soluna said the co-mining structure was first introduced to its Bitcoin platform in August, when the original agreement with Bitdeer was signed. The amendment carries the same structure as the original deal.

"We entered our first co-mining agreement with Bitdeer in August, and we are expanding it before that deployment is even finished," said John Belizaire, CEO of Soluna. "That is the strongest endorsement either of us could give the structure. Kati 1 is fully spoken for, and the operating history we are building there is what makes the next site possible."
