Zcash Miner Fortitude Adds 15 MW Nebraska Site to SPP Demand Response

Fortitude Mining said its 15-megawatt cryptocurrency mining facility in Aurora, Nebraska, has begun participating in Southwest Power Pool’s wholesale electricity markets through dispatchable demand response, allowing it to adjust consumption in response to grid instructions and market conditions.

The Zcash-focused miner said the arrangement is intended to improve power-cost management at the existing facility. It did not disclose expected payments, projected savings or how much of the site’s 15 MW capacity has been registered as dispatchable load.

Aurora receives electricity from Southern Public Power District under a wholesale supply arrangement with Nebraska Public Power District. NPPD Chief Executive Officer Thomas Kent said its ability to cut consumption can help manage peak demand. The announcement concerns how the facility operates within the power market, rather than an increase in its mining capacity.

Demand response lets electricity consumers help balance supply and demand by reducing usage. SPP operates both day-ahead and real-time power markets, with real-time prices updating every five minutes. Cutting demand can help the operator respond to changing conditions without relying solely on additional electricity generation.

Fortitude acquired Aurora’s power contracts, land, building and mining equipment in October 2025 for $7.65 million, partly using an existing hosting deposit, according to the definitive proxy statement for its proposed merger with HeartSciences.

The company has since expanded its Nebraska footprint. In July, it energized a 12 MW facility in Grand Island, and in August it announced completion of a $6.25 million acquisition of a 12.5 MW site in Prosser.

Fortitude said at the time that its portfolio included more than 60 MW of contracted power across seven locations in Nebraska, South Dakota, Texas and New York. Contracted power does not necessarily represent capacity operating at full utilization.

The Nebraska concentration also carries operating risks. A July weather event damaged mining and support equipment at Aurora, Prosser and Grand Island. Fortitude estimated repair costs and equipment losses at less than $1.5 million and the revenue impact on Zcash mining at about $1 million, according to the proxy statement.

Fortitude remains wholly owned by Digital Currency Group while it pursues the all-stock combination with Nasdaq-listed medical technology company HeartSciences. Shareholders are scheduled to vote Nov. 19. Completion remains subject to shareholder approval, Nasdaq requirements and other closing conditions.
