Summary

Novva's Arizona page, in its version modified on 31 August 2026 (bounded below by the Internet Archive copy of 14 July 2026, modified 2 July 2026, and matching the page-sitemap lastmod), presents 'Novva’s first Arizona Data Center campus' in Mesa: 160 acres with five data halls, 1.3 million sq ft of data-hall space and 200,000 sq ft of offices built over two phases, a 300 MW campus with water-free cooling. The July version placed the campus along Ellsworth Road, and Novva's 2024 announcement put the 160 acres at the northwest corner of Ellsworth and Warner roads. This records the Novva Mesa campus as announced on 31 August 2026. Construction and operation are not established: Maricopa County's air-quality register lists the 'Novva Phoenix' data-centre facility on parcel 304-31-141 as 'Not Yet Installed', and the City of Mesa permit dataset (current to 26 October 2026) has no permit on the parcel. The page's present-tense wording is read as the operator's description of the planned campus; the 300 MW, floor areas and the late-2026 first-phase target in the 2024 announcement are design figures and forecasts. evidence

Location details

Coordinates: 33.33974, -111.63947
Geometry licence: public-record-source-terms
Use scope: Campus locator
Scope class: official_tax_parcel_centroid
Authority: Official source
Source entity: Campus
Method: official_county_assessor_parcel_centroid
Derivation: direct_geometry
Precision scope: Centroid of Maricopa County Assessor parcel 304-31-141 (owner of record NOVVA PHOENIX LLC; 157.94 geodesic acres, about 786 by 1,089 m; jurisdiction Mesa), the campus parcel. It locates the planned Novva campus property, not a building, data hall, phase or surveyed boundary; no construction has been recorded on the parcel.
Horizontal uncertainty: Not reported
The assessor publishes no positional accuracy for parcel polygons; the centroid represents a 158-acre campus parcel whose building layout is not published.
Geometry evidence: ed9419eb

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
