What Is Being Proposed?

Official City records and public project descriptions identify Project Mustang as a proposed data-center development requiring City review. The project has also been publicly described as including substantial on-site power-generation infrastructure. The final equipment configuration, total electrical demand, generation operating profile, and end-user arrangements are not yet established by the records published on this site.

Who Is Involved?

Annexation, Zoning & City Review

City planning material identifies case PZ 2026-2715 for the 664.572-acre site and describes a voluntary annexation and proposed Employment Center zoning path. Separate City Council agenda material documents economic-development/legal discussion involving Big Watt Digital LLC and PH DIGITAL DATA CENTER DEVELOPMENT LLC.

Current status: City review and public-record collection are ongoing. This site does not treat a scheduled hearing, executive-session discussion, or negotiation as a final development agreement, incentive award, zoning approval, or authorization to construct.

Power & On-Site Generation

Electrical demand, grid interconnection, transmission requirements, substations, and on-site generation are central unresolved technical issues. ERCOT and PUCT records are being tracked separately, and the site distinguishes between documented regulatory activity and assumptions about the project's final electrical configuration.

Water & Wastewater

A primary-source PUCT proceeding, Control No. 55020, concerns NMCV Taylor Property Investors LLC's effort to obtain streamlined expedited release of its Taylor property from Manville Water Supply Corporation's water CCN. The project site's ultimate water source, cooling-water demand, wastewater arrangements, and enforceable reuse commitments remain important subjects of investigation.

Land, Financing & Infrastructure Context

Recorded instruments provide a continuous documentary chain for the 486.392-acre NMCV tract. NMCV acquired the tract in April 2021 and financed the acquisition with an original $4.875 million note secured by a deed of trust. Recorded renewals state principal balances of $3,868,770.40 in 2024, $3,783,380.55 in 2025, and $3,676,651.35 in 2026. The latest recorded extension set a July 17, 2026 maturity date; the site's post-maturity financing status remains unresolved in the records currently published here.

The property is also crossed by a Matterhorn Express pipeline easement. The final recorded easement exhibits show a 6.90-acre permanent easement with associated temporary work and access areas. The NMCV tract is bounded by FM 112 on the south and the Missouri Pacific Railroad right-of-way on the north.
