Enbridge seeks interest for West Texas gas pipeline project

Enbridge has launched a non-binding open season for its proposed West Texas Express pipeline, which would add more than 150 miles of gas infrastructure and initial capacity of up to 2 Bcf/day from the Permian Basin to West Texas and nearby markets. The project targets rising gas demand from utilities, power generators, industrial customers and data centers, while also serving Mexico, New Mexico and Arizona. The proposal is supported by growing associated gas output in the Permian, where the gas-to-oil ratio has risen 16% since 2021 to nearly 4,200 cubic feet per barrel.

Analysis

The investable issue is not headline capacity but whether contracted volumes demonstrate that Permian associated-gas growth has become a binding constraint on crude growth. A sustained improvement in Waha basis would modestly raise realized pricing for gas-heavy Permian operators, but the larger equity sensitivity is indirect: additional evacuation capacity reduces flaring, shut-in, and drilling-completion constraints, supporting oil volumes for FANG, OXY, DVN, and EOG over 6-18 months.

ENB should not re-rate materially on a preliminary commercial process alone. The project becomes relevant only if firm, creditworthy take-or-pay commitments support an attractive regulated return without materially increasing leverage; until then, the market should treat data-center demand as an unverified demand-marketing claim rather than incremental EBITDA. KMI is a potential second-order loser if new westbound capacity competes with its Southwest/Mexico-connected assets, although existing interconnectivity and contracted service could limit the impact.

Near term, the more actionable signal is Waha-Henry Hub basis: a narrowing spread after binding commitments would validate regional scarcity and favor Permian producers; a persistently wide or worsening discount would indicate that the proposed build is insufficient, delayed, or commercially unnecessary. Over 1-3 months, open-season results and disclosed anchor shippers are the catalyst; over 6-18 months, permitting, capital cost inflation, Mexican demand growth, and competing pipeline expansions determine returns. The thesis is falsified if commitments are weak, project economics require unusually high tariffs, or Waha basis fails to respond despite continued Permian oil growth.

Key Decisions for Investors

• No immediate directional ENB position: wait for binding shipper commitments, capital cost, in-service date, and expected return disclosure. Initiate an ENB overweight only if contracted capacity is sufficient to make the project EBITDA-accretive without a leverage-guidance increase; otherwise the likely stock impact is immaterial versus ENB's existing asset base.
• Establish a 1-3 month monitoring trade framework: go long FANG or OXY versus EQT only after Waha-Henry Hub basis narrows materially and remains tighter for at least two weekly flow reports. The trade captures Permian realization/volume relief versus Appalachian gas exposure; exit if Waha discounts re-widen or Permian production guidance is cut.
• Watch KMI for relative underperformance versus ENB following a successful binding open season. A long ENB/short KMI pair is appropriate only if the disclosed route and tariffs directly target KMI-connected Southwest or Mexico demand; avoid the pair if KMI secures incremental contracts or demonstrates that its existing network benefits from incremental supply.
• Set an alert for announced anchor shippers among utilities, Mexican buyers, LNG-linked marketers, or large industrial customers. Commitments from investment-grade counterparties are the key de-risking event; speculative data-center demand without named contracts is not sufficient to underwrite a midstream valuation uplift.
