Cryptomining firm Soluna has announced the completion of a 48MW expansion at its Project Dorothy 2 data center campus in West Texas.

The expansion brings the total capacity of the campus to 100MW. Groundbreaking of the expansion occurred last September, with an original completion date expected in Q1 of this year.

Most of the project's capacity is dedicated to Bitcoin mining, with a small amount to AI computing. The 98MW of Bitcoin mining capacity is split between 25MW of proprietary mining and 73MW of hosting across five customers.

The campus is built behind the meter at a 150MW wind farm, using otherwise curtailed energy.

The site is managed through Soluna’s MaestroOS automation and monitoring platform, which the company says improves uptime and grid responsiveness.

“Dorothy 2 represents disciplined execution and a major step forward for Soluna,” said John Belizaire, CEO of Soluna. “Our team delivered a complex, large-scale project on schedule, proving that Renewable Computing can be deployed quickly, reliably, and sustainably. It’s exciting to be growing again.”

Following the expansion, Soluna’s total operational capacity stands at 123MW. Soluna has 11 data center sites in various stages of development: Project Sophie, Project Dorothy 1 & 2, Project Kati 1, Project Grace, Project Rosa, Project Hedy, Project Ellen, and Project Annie. The company claims a long-term pipeline totaling 19 projects and up to 2.8GW of capacity.

The company names its sites after pioneering women in science; Project Dorothy honors NASA mathematician Dorothy Vaughan.

The company has dealt with significant financial issues over the past year. In October, it was reported that it was no longer facing delisting from the Nasdaq stock exchange after regaining compliance with the minimum bid price requirement under Nasdaq listing rules.

Aside from a brief period in July, Soluna’s stock had traded below $1 since early March, reaching as low as 40 cents.
