Vantage Data Centers — "Frontier" Mega-Campus

Project compiled: 2026-04-27

1. Project envelope

2. Phase 1 power architecture

Engine count, MW per engine, and total nameplate MW are NOT disclosed in any primary source retrieved. The TCEQ NORI confirms the facility triggers federal PSD AND GHG PSD review (which means it exceeds Clean Air Act major-source thresholds), but does not state engine specifications. The NORI directs that the full application is “available for viewing and copying at the TCEQ central office, the TCEQ Abilene regional office, and the Abilene Public Library.” 3Government sourcePrimary182467 nori englishOfficial government publication.

3. Vantage–VoltaGrid commercial relationship (predates Frontier launch)

The Feb 11, 2025 partnership press release does NOT name Texas, Shackelford County, Frontier, Abilene, or any specific facility location.9voltagrid.comReferenceVantage data centers and voltagrid establish partnership to deploy more than one gigawatt Click to open the source in a new tab.voltagrid.comOpen source → It is a portfolio-wide MOU; the Frontier-specific deployment was unveiled six months later (Aug 19, 2025).

13. Sources NOT cited (and why)

The following types of sources were consulted during research but deliberately excluded from this profile because they fail the primary-source standard:

• Trade press: Power Magazine, Data Center Dynamics, Construction Owners, Bisnow, Reuters, Bloomberg
• Local press: Albany News, Reporter-News, KTXS, Brownwood News
• Aggregators: GEM Wiki, Wikipedia, DataCenterMap, mapcarta, interconnection.fyi, dieselnet.com, OpenCorporates
• Law-firm advisories: Baker Botts, Weil, K&L Gates
• Manufacturer marketing pages (used only as reference for product specs the manufacturer itself published — not as evidence of what is installed at Frontier)
• Social media other than the operator’s verified handle

The widely cited “INNIO Jenbacher J624 / 4.5 MW per unit / 210 engines / 700 MW combined” specification appears only in trade press and aggregators and is not incorporated into this profile. Engine model is confirmed only at the family level (“Jenbacher reciprocating engines”) by Oracle’s own Fact Sheet [^7]; specific MW/count requires retrieval of TCEQ permit 182467’s full application body, which is referenced in [^3] as available “at the TCEQ central office, the TCEQ Abilene regional office, and the Abilene Public Library” but was not retrieved during compilation.
