A heated Texas Senate interim committee hearing over proposed 765-kilovolt (kV) transmission lines has quickly turned into a broader political fight, with some of the state's top Republican leaders urging regulators to halt the project while lawmakers reconsider how major transmission lines are approved.
The debate centers on the state's Strategic Transmission Expansion Plan (STEP), which includes new 765-kV transmission lines as part of the broader $33 billion Permian Basin Reliability Plan. The lines are designed to move electricity across Texas by connecting power generation with growing demand in West Texas, but doing so would require new transmission corridors stretching across private property.
Those property rights concerns dominated last week's hearing, where lawmakers and landowners questioned both the project itself and the process used to approve it. State Sens. Lois Kolkhorst (R-Brenham) and Phil King (R-Weatherford) expressed skepticism of the proposal, while residents warned that landowners have little time to organize protests once transmission routes are announced.
Within hours of the hearing, Senate Business and Commerce Chairman Charles Schwertner (R-Georgetown) called on the Public Utility Commission (PUC) to reject the pending certificates of convenience and necessity (CCNs) for the proposed transmission lines.
"We must reform the CCN process next session to ensure future projects are fair and transparent," Schwertner wrote on X.
A certificate of convenience and necessity grants a utility the authority to construct infrastructure, including high-voltage transmission lines, within a designated service area.
Schwertner also echoed testimony from landowners who argued the current process leaves property owners at a disadvantage.
"Landowners deserve a fair and transparent CCN process," he wrote. "Texans' property rights must be protected."
Lt. Gov. Dan Patrick soon joined the growing opposition, saying he agreed with Schwertner's call for the PUC to deny the pending applications.
"I agree with Chairman Schwertner in calling on the PUC to deny the pending applications for 765-kV transmission lines, and not consider re-applications, until the transmission companies can address the serious concerns raised by landowners at Wednesday's hearing," Patrick wrote on X.
Patrick questioned whether the proposal from the PUC and the Electric Reliability Council of Texas (ERCOT) could move forward without the support of affected landowners, arguing that expanding the electric grid should not come "at the expense of private property rights."
"During the 90th Legislative Session beginning in January 2027, the Texas Senate will prioritize addressing this issue," he added.
The issue is also headed to the Texas House. Speaker Dustin Burrows (R-Lubbock) announced that the House Committee on State Affairs will hold its own hearing on the proposal Aug. 19.
"The Texas House remains committed to policies that support the responsible planning and development of our rapidly growing state," Burrows said.
Texas Railroad Commissioner Wayne Christian added another layer to the debate by tying the transmission proposal to the state's broader energy policy.
"Texas needs more infrastructure to strengthen grid reliability, but the 765-kV transmission line proposal is not the cure. It is the consequence," Christian wrote on X.
He called the project the "bill coming due" after "years of energy policies that prioritized bending the knee to climate catastrophism and 'all-of-the-above' energy sycophancy while ignoring the clear and obvious shortcomings of that approach."
Questions over Texas' renewable energy buildout surfaced repeatedly during the hearing. Several panelists argued that the rapid growth of wind and solar generation—particularly in West Texas—has outpaced the state's transmission network, creating congestion and increasing the need for additional high-capacity lines.
Supporters of the project argue that is precisely why the Permian Basin Reliability Plan was created.
Power West Texas, a campaign launched last week in support of the plan, pointed to House Bill 5066, which lawmakers approved in 2023 to address transmission needs in the region.
"The Texas Legislature overwhelmingly passed House Bill 5066 in 2023" to address West Texas transmission needs, the organization said.
"The Permian Basin Reliability Plan is moving through the process as the law requires.
"The need is documented, the plan is approved, and the consequences of further delay are significant for the state's economic engine and America's energy security."
The debate arrives as Texas continues to weigh other challenges facing its electric grid. Although Gov. Greg Abbott has said little publicly about the proposed transmission lines, he has recently focused on the rapid growth of data centers and their potential impact on electricity demand.
On Monday, Abbott directed the PUC and ERCOT to audit all data centers moving through ERCOT's interconnection process before allowing additional projects to proceed. The directive requires developers to disclose ownership information, projected electricity use, water consumption, community impacts, reliance on private generation versus the grid, and financial details. According to reports, ERCOT responded the same day by postponing its ongoing "Batch Zero" study examining the impact of large electric loads.
Abbott's directive followed recent remarks supporting limits on data center construction near rural neighborhoods, another indication that grid reliability—and how Texas chooses to expand it—is likely to remain a major issue heading into the 2027 legislative session.
