Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

Source notes
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.
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.
