Power & Grid

ERCOT, transmission, substations, interconnection, and electrical demand.

The October development agreement and current Taylor Technology Campus materials now sit alongside the August Project Mustang power disclosures. The record contains several different capacity and grid-operation descriptions that should be preserved and reconciled rather than silently merged.

What the Current Project Records Show

August 2026 proposal / disclosure

Oncor identified as electric provider

Kimley-Horn states that Oncor Electric Delivery is the electric provider for the site and that the development has been in frequent contact with Oncor. Additional service information remains to be clarified.

Substations may be located throughout the campus

The EC Plan allows electrical substations, switchyards, transformers and associated electrical infrastructure throughout the property as needed to support the closed-campus employment center.

Potential generation scale is very large

The plan lists 84–112 gas-fired units at 12.5 MW each. Simple arithmetic implies approximately 1.05–1.40 GW of aggregate gas-generator nameplate capacity if all listed units are installed. This is not a statement of continuous output or final installed capacity.

August 2026 proposal / disclosure

Approximately 700 MW data-center load / 1,040 MW on-site generation

At the August 18 hearing, project representatives described approximately 700 MW of data-center load and roughly 1,040 MW of on-site generation. They also described initial operation as potentially isolated from the electric grid and said the generation is not intended for exporting or selling power.

Hearing disclosure
October 2026 development agreement

Power generation remains part of the defined Project

The agreement defines the Project to include the data-center facility, a power-generation facility, substations, switchyards, transformers, inverters, converters, transmission/distribution lines and interconnection infrastructure. It does not establish a final primary-generation MW cap in the provisions reviewed here.

Current agreement

Capacity & Grid Claims Reconciliation

Do not collapse these into one number: August hearing disclosures described about 700 MW of data-center load and ~1,040 MW of on-site generation; the withdrawn August equipment schedule implied about 1.05–1.40 GW if all listed units were installed; October 5 reporting described a 500-MW data center. At the October 8 hearing Big Watt described the campus as self-generated and not connected to the grid, while the City’s current project page says excess power could be sold back to the grid. The agreement expressly restricts sustained export by backup generators, but that clause does not by itself resolve primary-plant export. City project page ↗ · Taylor Press Oct. 5 report ↗

What Is Still Unknown

  • Final data-center load/capacity and final installed primary-generation capacity.
  • Whether primary on-site generation will be electrically islanded, grid-connected for export, or configured for some other interconnection arrangement.
  • Final Oncor/other transmission interconnection, substation and upgrade requirements.
  • Any final ERCOT project identifiers or studies attributable to the site.
  • Responsibility and cost allocation for project-driven off-site electrical infrastructure.
