Summary

TCEQ's Central Registry (North Texas file, rows refreshed 26 October 2026) lists regulated entity RN112532585 'CEMCO-348 CBP Sweetwater 2 Data Center', a concrete batch plant reached from Rotan 14.1 miles east on TX-92 and 0.9 mile north on FM 540 on the west side of the road, with air permit registration 185401L001 pending for Van Eaton Ready Mix Inc, dated 18 September 2026; it also lists RN112486196 'IREN Sweetwater 2 Data Center Project Substation Rough Grad[ing]' at 1730 FM 540, Hamlin, for IE US Development Holdings 7 Inc (construction stormwater authorization active since 9 July 2026). IREN's undated Sweetwater page describes Sweetwater 2 as the 600 MW, 500-acre second site of its 2 GW Sweetwater hub, with substation energization targeted for 2027. This records IREN's Sweetwater 2 data-centre project as announced on 18 September 2026, the date of the government record naming 'Sweetwater 2 Data Center'. A batch-plant registration and substation-grading stormwater coverage are not consent for the data-centre development and do not establish building construction; IREN's undated 'under construction' label is not used, and the 600 MW is planned power capacity, not IT load. Sweetwater 1 is a separate site and is not included. evidence

Location details

Coordinates: 32.93202, -100.22130
Geometry licence: public-use-as-is
Use scope: Campus locator
Scope class: official_tax_parcel_union_centroid
Authority: Official source
Source entity: Campus
Method: official_statewide_parcel_service_parcel_union_centroid_epsg3083
Derivation: direct_geometry
Precision scope: Centroid of the union of the three contiguous Fisher County parcels owned by IE US Development Holdings 7 Inc in the TxGIO StratMap parcel service (Fisher Appraisal District, tax year 2026): 3891 (213.23 acres), 3896 (254.53 acres, situs FM 540) and 33181 (76.77 acres). The union is one polygon of 548.38 geodesic acres, about 1.62 km east-west by 1.61 km north-south; the centroid lies inside it, 430 m from the boundary. It locates the Sweetwater 2 landholding (campus), not a building, the substation, a footprint or a construction extent.
Horizontal uncertainty: Not reported
Appraisal-district parcels carry no published positional accuracy; the centroid represents a 548-acre landholding whose vertices lie up to 1.15 km away, and the positions of the planned buildings and substation are not published.
Geometry evidence: 04c6d391

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.
