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.

Reported lifecycle history

  1. Permitted

    Lyon County Board of Commissioners voted 3-1 to approve the planned unit development rezoning. Final PUD design approval, state permits (NDEP, State Engineer) and land purchase are still outstanding.

    Underlying source

Source notes

Roughly 505 acres in Mason Valley near Yerington; a 4.6 million-square-foot campus with north and south sub-campuses, a battery energy storage system, a natural gas plant, a substation and power lines across two parcels. First phase would provide 150 MW of the 1,000 MW total. Copia Power has one year to file its final PUD. Lyon County is drafting a stricter data center ordinance that will not apply retroactively to Monarch.

Copia Power would initially self-supply from an on-site 500 MW natural gas plant plus battery energy storage, phasing in NV Energy grid supply later. Project representatives cited NV Energy's resource plan commitment of 2,550 MW to data centers.
