Soluna Holdings, Inc. announced the purchase of 8,250 Bitmain Antminer S19s, S19j Pro and S19j Pro+ for its Project Dorothy 1B data center in Texas. The purchase is estimated to result in 860 PH/s of hashrate with an average efficiency of 29.9 J/TH, and at a cost of $11.25 $/TH inclusive of all fees, import, and taxes. The 25 MW Project Dorothy 1B is a proprietary mining joint venture between Soluna and Navitas Global.

The first 5 buildings, which is approximately 6 MW, are set to be energized by the end of June. The remainder is expected to be completed and energized in the third quarter. The site's run-rate revenue from mining is approximately $18 million annually.

Once Project Dorothy 1B is operational, the 50 MW Project Dorothy phase 1 will be fully online with a mix of hosting and proprietary mining.
