Provider notes
Energy. On-site generation with a minimum $500M initial investment; carbon-negative operations via partnership with Spiritus and Casper Carbon Capture, combining natural gas with proprietary geothermal systems and carbon capture.
Water. Developer describes proprietary aquifer, non-consumptive water-cooling systems for the high-density compute halls.
Community. Neighboring landowners mounted "fierce pushback" over noise, heat, fumes, and traffic concerns, prompting developers to weigh relocating to an alternate parcel as of July 2026 (no denial or lawsuit yet).
What the source record says
1.5GW campus proposed on the Falls Ranch property spanning the Natrona/Converse county line near I-25, roughly 10 miles east of Casper. Site plan still in flux as of July 2026, with developers weighing an alternate parcel south of I-25; targeted operational by 2028.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
