PUC Approves 370-Mile Transmission Line to Permian Basin
The Public Utility Commission of Texas approved a 370-mile electricity transmission line to the Permian Basin on Friday, marking the second such approval in two weeks, Permian Basin Oil & Gas Magazine reports.
The line crosses 14 counties in south Texas, including Bexar, Kerr, Medina and Uvalde. Commissioners directed the two transmission companies involved to work with landowners on route modifications after residents raised concerns the lines would damage their properties.
Market Impact
The approval follows an Aug. 28 PUC hearing where commissioners signed off on two 765-kilovolt transmission lines running from Bosque County across at least 30 counties in north and west Texas. Those lines, according to a Texas Tribune report cited by Permian Basin Oil & Gas Magazine, represent the first projects under the Permian Basin Reliability Plan, a program the Texas legislature established in 2023 to shore up grid access for the oil and gas industry.
Industry leaders framed the buildout as urgent. Todd Staples, president of the Texas Oil and Gas Association, told commissioners that “America’s most important energy security region is at risk,” warning that West Texas operators, homes, schools and businesses all face threats without a dependable, affordable connection to the ERCOT grid. Betsy Madru, a lobbyist for Midland-based Diamondback Energy, testified that her company generates 80 megawatts of its own power to supplement the 330 megawatts it draws from the grid, calling the reliability plan too important to sideline.
What It Means for Subcontractors
- Transmission line construction crews, civil subs and substation contractors should prepare to bid work along the newly approved 370-mile south Texas corridor spanning Bexar, Kerr, Medina and Uvalde counties.
- The Bosque County-anchored 765-kV lines crossing 30-plus north and west Texas counties represent a separate, larger multi-year package tied to the Permian Basin Reliability Plan, worth tracking for EPC subcontract announcements as the two transmission companies move from PUC approval to construction planning.
- Landowner-driven route modifications ordered by the PUC mean survey crews, right-of-way negotiators and civil engineering subs may see scope changes before final alignments are locked, so firms bidding this work should build flexibility into early-stage contracts.
- Permian operators like Diamondback Energy, which currently self-generates 80 megawatts to cover gaps in its 330-megawatt grid draw, are a signal of pent-up demand. Electrical and mechanical subs serving E&P customers should anticipate additional substation and interconnection work as grid capacity expands.
