MARA Granbury Data Center, Hood County, Texas

MARA Holdings operates the Granbury facility in Hood County, south of the Dallas–Fort Worth market. TYPE3’s map data identifies it as an operating crypto-mining data center and carries a 200 MW map value marked as an estimate. MARA’s 2025 Form 10-K reports approximately 300 MW of total capacity, so the two MW figures should remain labeled rather than combined. The filing also reports 12.3 EH/s of energized hashrate at December 31, 2025. That dated hashrate evidence supports an energized site at year-end, but it does not reveal current load, spare capacity, or a dispatch commitment.

The site uses large containerized liquid-immersion-cooled systems. Public local reporting and community materials describe disputes around mining noise and local impacts. Those accounts are relevant context for site-selection and infrastructure diligence, but they are not by themselves a regulatory finding. The record is strongest when it places the operator, county, estimated map MW, total-capacity statement, energized hashrate, operating evidence, and community reporting on one dated timeline.

The 300 MW figure is total site capacity, not a promise that 300 MW is continuously energized or available to a new customer. For this site, the distinction matters because the dated 12.3 EH/s figure confirms energized mining at year-end without answering how much of the estimated 200 MW map value is in use today.
