Understanding Texas Transmission Line Projects
Protecting Your Land and Legacy from Emerging Grid Expansion
For decades, the Texas landscape has been defined by its wide-open spaces and productive acreage. Today, that landscape is shifting. As the state’s population surges and industrial energy demands hit record highs, a massive wave of Texas transmission line projects is moving across the state.
From the Permian Basin to the heart of Central Texas, utility companies are racing to build the infrastructure needed to support a growing grid. For landowners, these projects are more than just a matter of public utility. They are a direct challenge to private property rights and future land use.
The Scale of Transmission Expansion in Texas
Why Texas is Investing Billions in New Grid Infrastructure
Texas is currently undergoing one of the most aggressive power grid overhauls in its history. This expansion is driven by several factors: population and industrial growth that has outpaced previous grid forecasts, the rapid electrification of the oil and gas industry in West Texas, surging demand from data centers, cryptocurrency mining, and hydrogen production, and the need to manage transmission congestion partly caused by the influx of intermittent renewable energy sources.
The Public Utility Commission of Texas (PUCT), along with the Electric Reliability Council of Texas (ERCOT) and the Texas Legislature, have greenlit tens of billions of dollars in new infrastructure through initiatives like the Texas 765-kV Strategic Transmission Expansion Plan (TX 765-kV STEP) and the Permian Basin Reliability Plan (PBRP). These are not minor upgrades; they are “extra-high-voltage” projects designed to move massive amounts of power across hundreds of miles of private land.
What Are 765 kV Transmission Lines?
Extra-High-Voltage (EHV) Technology and Its Impact on Private Property
While Texas has long utilized 138 kV and 345 kV lines, the new standard for long-distance reliability is the 765 kV transmission line.
- Higher Voltage, Higher Impact: A 765 kV line is an “electric expressway.” By operating at a much higher voltage, it can transport power more efficiently with less energy loss over long distances.
- Massive Infrastructure: These towers are significantly larger than standard power poles. They typically range from 140 to 180 feet tall; roughly the height of a 15-story building, and can span 1,400 feet between structures.
- Wider Easements: Because of the voltage and scale, these lines require a much larger right-of-way (ROW), often reaching 200 feet or more in width.
The introduction of 765 kV transmission lines in Texas represents a fundamental shift in how power is moved, requiring more land and creating a far more permanent visual and physical footprint on the property they cross.
Active & Proposed Texas Transmission Line Projects
As of May 2026, several major projects are moving through the regulatory phases. These projects are often divided into regional corridors:
- Longshore to Drill Hole (765 kV): Spanning counties like Andrews, Ector, and Midland.
- Big Hill to Sand Lake (765 kV): Affecting Crane, Pecos, Upton, and surrounding counties.
- Howard to Solstice (765 kV): A 370-mile project connecting Pecos County to San Antonio.
- Dinosaur to Longshore (765 kV): Running from Somervell County out toward West Texas, crossing through counties like Erath, Comanche, and Eastland.
- Bell County East to Big Hill (765 kV): Affects a broad study area including Burnet, Williamson, Bell, and Lampasas counties.

How to Find and Read Texas Transmission Line Maps
Knowing where to look, and what you’re looking at, is the first step in protecting your property. Early-stage maps rarely show a single line. Instead, you will see a “Study Area” or a web of “Alternative Route Segments” that may eventually combine to form the final approved route.
From Community Meetings to PUCT Filings: What Each Map Tells You
The first maps a landowner usually sees aren’t filed with a regulatory agency at all. They appear at open community meetings held by the utility in the affected study area. These early maps often show broad corridors and multiple potential routes, and attending one of these meetings is frequently a landowner’s first concrete sign that a project is nearby.
Later, more detailed maps are filed with the PUCT as part of the utility’s formal Certificate of Convenience and Necessity (CCN) application. These filings include topographic maps and segment-level detail that show exactly which properties fall within each potential route.
Where to Find Maps:
- PUCT Interchange: All official filings, including detailed topographic maps and “link” segments, are stored in the PUCT’s digital archives.
- Utility Project Pages: Companies like Oncor, AEP Texas, and LCRA maintain project-specific websites with interactive map tools.
- Community Open Houses: Early-stage corridor maps are often shared in person before they appear in formal filings.
How to Interpret a Study Area
Once you’ve located a map, here’s what you’re looking at:
- Corridors: The broad paths the utility is considering.
- Links: Individual segments that can be combined to form dozens of potential routes.
- Preferred vs. Alternate: While the utility must name a “preferred” route, the PUCT can (and often does) pick segments from the “alternate” routes based on public feedback.
Signs a Transmission Line May Affect Your Property
Landowners are often the last to know their property is in the path of a new project. The signs of utility activity look different depending on whether a route has been finalized, so it helps to know what to watch for at each stage.
Before a Route Is Selected: Early Warning Signs
During the planning and routing phase, signs are subtle but meaningful:
- Open House Invitations: Direct mailers inviting you to a local community center to “view project updates.”
- Inclusion in a Study Area: Your property falling within a broad corridor on early utility maps.
- Neighbor Conversations: Word-of-mouth news that nearby landowners have received notices.
After a Route Is Approved: Signs the Project Is Moving Toward Your Land
Once the PUCT approves a final route, the activity becomes more direct and formal:
- Formal Notices: Receiving a certified letter from a utility company is one of the most critical signals that your property is on the approved path.
- Survey Access Requests: Utilities asking permission to enter your property for engineering or environmental surveys.
- Right-of-Way Agent Contact: A representative reaching out to discuss easement terms or initial offers.
How New Transmission Lines Affect Landowners
Immediate and Long-Term Consequences for Property Values
While the compensation for these easements come later in the process, the high-level impact of these new transmission lines in Texas is immediate.
- Property Fragmentation: Massive towers can split productive pastures, potentially interfering with center-pivot irrigation.
- Aesthetic and Value Impact: The 180-foot 765 kV structures are visible for miles, potentially decreasing the resale value of recreational or residential-transition land.
- Access Requirements: Utilities will eventually require permanent access to the easement, which can involve new gates or roads on your property.
What Happens Next
Moving from Project Discovery to Legal Protection
The lifecycle of a transmission project moves through three distinct phases:
- Planning & Routing: Where the utility proposes routes and the landowners are able to participate.
- Approval: The PUCT selects the final route, at which point the path is “locked.”
- Acquisition: The utility begins contacting landowners to secure easements through negotiation or, if necessary, condemnation.

Frequently Asked Questions
Yes. Due to record-breaking demand and grid reliability concerns, billions of dollars are currently being invested in new high-voltage projects across the state, particularly the 765 kV “backbone” expansion.
A 765 kV line is an extra-high-voltage power line. It uses taller towers (up to 180 feet) and wider easements (200+ feet) to move more electricity more efficiently than the standard 345 kV lines seen in the past.
Official maps are filed with the PUC of Texas under the project’s CCN docket. You can also find interactive maps on the project-specific websites hosted by utilities like Oncor or AEP.
If your property is within a designated “Study Area,” there is a possibility a route could be chosen that crosses your land. Early monitoring of PUCT filings is the only way to know for sure if your acreage is at risk.
