Texas Regulators Pause a Major 765-kV Transmission Line — What the Hold Means for Your Bill

What the PUCT Actually Did

The case at issue is the Longshore Switch–to–Drill Hole Switch line, one of five proposed 765-kV projects moving through the state’s approval process as part of the Permian Basin Reliability Plan. The line would connect electric infrastructure south of Big Spring to an area north of Pecos, in the heart of the oil-and-gas region where electricity demand is climbing fast.

According to reporting from KXAN (Austin) on June 17, 2026 and trade coverage from E&E News (“Texas slows electric transmission review process,” June 18, 2026), commissioners voted to abate the case — effectively putting the routing decision on hold — after opponents argued regulators should first answer broader questions about whether the project is needed at its current scale.

The pause followed an unusual show of legislative interest. More than 40 Texas lawmakers (reported as 43 — 34 members of the House and 9 of the Senate) filed or backed a friend-of-the-court brief urging the commission to fully evaluate the plan before making what they described as “irreversible decisions.” Supporters of the lines, including some oil-and-gas industry groups, have argued the Permian buildout is essential to keep up with surging West Texas load and to maintain reliability. The commission’s decision does not end the project — it delays it.

Why a Transmission Line Affects Your Bill

High-voltage transmission lines are paid for by all customers in the ERCOT region through the transmission-and-distribution portion of the bill — the regulated charge from your local TDU (Oncor in Dallas–Fort Worth, CenterPoint in Houston, AEP Texas, or TNMP). These delivery charges are set by the PUCT, not by your retail provider, and they are updated on a fixed schedule each March 1 and September 1.

The dollars at stake are large. A Texas Public Policy Foundation study cited in the coverage estimated that the 765-kV projects approved through December 2025 carry a price tag of roughly $33 billion, with lifetime costs approaching $100 billion. That sits on top of a broader wave of transmission spending — ERCOT stakeholders endorsed about $6.5 billion in additional projects in May 2026, on top of a $9.4 billion 765-kV plan approved in late 2025. Whether, and how quickly, those lines get built helps shape the future trajectory of the delivery charge on every Texas bill.

That is the honest consumer angle of this story: a pause could moderate how fast delivery charges rise, or it could defer investment that supports reliability as demand grows. The effect is indirect and plays out over years — not something you’ll see on next month’s statement.

What It Doesn’t Change: Which Plan Is Cheapest for You

Here is the part that matters most when you shop. Because delivery charges are identical for every retail provider in your TDU territory, they never change the ranking of plans. The same Oncor or CenterPoint delivery charge rides along no matter which company you sign with, so the only lever you actually control is the energy charge — the rate set by your retail plan.

And the cheapest energy rate depends on your usage, not the advertised headline number. A plan tuned to look cheap at exactly 1,000 kWh can quietly become one of the most expensive options at 600 kWh or 2,000 kWh — the trap we call the 1,000 kWh illusion. The way to avoid it is to compare each plan’s real effective rate at your actual monthly usage, which is exactly what our comparison tool does.

If predictability matters to you during a period of grid expansion and policy uncertainty, a fixed-rate plan locks your energy charge for the contract term, insulating you from wholesale-market swings. Variable and indexed plans can move with the market — helpful sometimes, painful during summer demand peaks.

The Consumer Takeaway

Don’t expect a paused transmission line to lower your bill anytime soon — and don’t let the headline distract you from the one decision that genuinely moves your monthly cost. Watch your delivery charge change on March 1 and September 1 (it’s out of your hands either way), and put your energy on the energy charge you can control:

• Compare plans on their effective rate at your real usage, not the 1,000 kWh advertised rate.
• Consider locking a fixed-rate plan if you want protection from summer volatility.
• Check your contract expiration date so you’re not rolled onto a high month-to-month rate.
• Remember the delivery charge is the same across all providers in your area — so it’s never a reason to pick one plan over another.
