PUCT Docket 59315, Oncor application for a 765 kV transmission line across 22 counties

Power and the gridPublic Utility Commission of TexasBorden, Bosque, Brown, Callahan, Coke, Coleman, Comanche,...Public meeting

Oncor Electric Delivery has applied to amend its certificate of convenience and necessity to build the Dinosaur Switch to Longshore Switch transmission line. The application covers a corridor crossing 22 named counties in central and west Texas. The docket has drawn one of the largest volumes of landowner filings in recent PUCT practice. Those filings include intervention requests, protests and a county resolution. The commission has the docket set for discussion and possible action at its open meeting on August 21st, 2026. That meeting is in a hotel ballroom in Austin rather than in the hearing room. That meeting takes up two Oncor 765 kV applications and nothing else before it closes. The commission issued its order on August 28th, 2026, amending the certificate to include the line and approving route 559. The administrative law judges had found the utility did not fully comply with the public meeting rule for links added after that meeting. The commission read the rule to require only one meeting before the application was filed. The order records the transmission providers projecting an exponential increase in non oil and gas load in the Permian Basin region, named as cryptocurrency mining, data centers and hydrogen electrolysis.

How to take part

The commission took the docket up at its open meeting and issued its order on August 28th, 2026. The whole record stays public through the Interchange under control number 59315, where landowners intervened and filed protests in their own names. A party that wants the commission to look again files a motion for rehearing in the same docket.

How this decision moved

One dated line per check, oldest first. A line that says nothing changed means somebody looked and it had not.

  1. 2026-08-18

    The filing index moved from 5782 to 5790. The calendar entry for the August 21st open meeting no longer names Docket 59315. That entry now gives the AT&T Hotel and Conference Center rather than Commissioners Hearing Room 7-100.

  2. 2026-08-19

    Checked and unchanged. The filing index stands at 2,000 and the most recent entries are still the intervention requests and protestor comments of March 17th.

  3. 2026-08-20

    The docket is on the August 21st agenda after all. The published agenda for that open meeting names Docket 59315 as item 3, marked for discussion and possible action, and names a second Oncor 765 kV application as item 2. The calendar feed's entry for the meeting names no docket because no feed entry names one. The filing index now reports 5793 filings, and the web view lists only its first page of them, so a count taken from the rows on screen understates the docket.

  4. 2026-08-21

    Checked. The commission's published agenda for the August 21st, 2026 open meeting still names Docket 59315 as item 3 for discussion and possible action. The filing index has moved from 5793 to 5797 since the last check.

  5. 2026-08-26

    The filing index moved from 5797 to 5810, so the docket took new filings over the weekend. The case style is unchanged and the application is still pending before the commission. The landowner protests and the Comanche County resolution are still on the record.

  6. 2026-08-26

    Checked and unchanged. The interchange filing list for Docket 59315 answers and its newest filing is still dated March 17th, 2026. No final order has been entered.

  7. 2026-08-29

    The commission decided this on August 28th, 2026. It amended the certificate to include the line and approved route 559 across the twenty two counties the application named. The administrative law judges had found the utility did not hold a further public meeting for links it added afterwards. The commission approved the line anyway, on a reading that the rule requires only one meeting before filing.

  8. 2026-09-02

    The route application is still the largest file the commission holds on this line and the record shows no change to the approved route. Landowner interventions and protests remain on it.

  9. 2026-09-05

    The commission's filing index for the line has taken further filings since the last reading and the approved route is unchanged. The landowner protests and interventions are still on the docket.

  10. 2026-09-08

    The Dinosaur Switch to Longshore Switch application is still docketed under the same case style and still names the same counties. One more filing has been entered since the record last read the index.

  11. 2026-09-09

    The commission's filing index for the line has taken further filings since the last reading. The approved route is unchanged and the landowner protests and interventions are still on the docket.

  12. 2026-09-12

    The commission's filing index for the line has taken further filings since the last reading. The approved route is unchanged and no party has asked the commission to reopen it.

  13. 2026-09-13

    The approved route for this line is unchanged and the docket is still taking filings.

  14. 2026-09-16

    The docket's own case style still describes the Dinosaur Switch to Longshore Switch line and still names all twenty two counties it would cross. The docket is live and taking filings, and no order disposing of it has appeared.

  15. 2026-09-19

    The line is still approved on the terms the commission set. The docket goes on taking filings after the decision, so every count of them here is true of the day it was read rather than of today.

  16. 2026-09-24

    The commission's order approving the line still stands on its original terms. The docket keeps taking filings after the order, so any count of them belongs to the day it is read.

  17. 2026-09-27

    The commission's order approving the line still stands as issued. Filings keep reaching the docket without reopening it.

  18. 2026-09-30

    The commission's approval of the line still stands as ordered, and the filing that carries it reads the same.
