Texas Utility Bill Dispute: How to Challenge an Overcharge in a Deregulated Market
In most of Texas you pick a Retail Electric Provider, but a different utility owns and reads your meter. Knowing who is responsible for what — and your rights under PUCT rule 25.480 — is the key to winning a Texas bill dispute.
Why disputing a Texas bill is different
Most of Texas has a deregulated electricity market. You buy your energy from a Retail Electric Provider (REP) — the company that sends your bill — but a separate Transmission and Distribution Utility (TDU) owns the poles, wires, and your meter, and is the one that actually reads it. The big TDUs are Oncor, CenterPoint, AEP Texas, and Texas-New Mexico Power. That split matters: an error can come from the REP (your rate or plan charges) or from the TDU (the meter read and delivery charges), and you fix each one differently.
- REP: the company you pay; controls your energy rate and plan charges
- TDU: owns and reads your meter; sets the delivery charges on your bill
- Municipal utilities (Austin Energy, CPS Energy) and co-ops are NOT deregulated — different rules apply
Step 1: Is the error the REP's or the TDU's?
Pull up your plan's Electricity Facts Label (EFL) — every REP must give you one — and compare the energy rate you agreed to against what you were billed. If the rate or plan charges are wrong, that is a REP problem. If the kWh used, the meter read, or the delivery charges look wrong, that points to the TDU's meter data. Sorting this out first tells you who to call and saves you from being bounced between them.
- Rate / plan / fees wrong on the EFL comparison → REP
- kWh, meter read, or delivery (TDU) charges wrong → TDU meter data
- An 'estimated' read is a TDU issue even though the REP sends the bill
Your backbilling rights in Texas (PUCT rule 25.480)
Texas limits how far back a provider can charge you for its own underbilling. Under the PUCT customer-protection rules, a REP generally cannot hold you responsible for corrected (underbilled) charges unless it bills them within 180 days of the original bill. Separately, back-charges should not reach more than six months before the error was discovered. And when the underbilled amount is $50 or more, the REP must offer you a deferred payment plan for the same length of time as the underbilling. The main exceptions are meter tampering by the customer or a TDU meter-error correction.
- REP underbilling corrections must be billed within 180 days of the original bill
- Back-charges shouldn't extend more than 6 months before the error was found
- Underbilling of $50+ entitles you to a deferred payment plan of equal length
Estimated reads and catch-up bills in Texas
When the TDU cannot read your meter, it estimates — and the correction lands later, sometimes as a large catch-up charge on your REP bill. That is exactly the scenario the backbilling limits above are meant to contain. Confirm whether your reads were actual or estimated before paying any catch-up amount.
Step-by-step: how to dispute and escalate
Always start with your REP in writing. Under PUCT rules the REP must promptly investigate a billing dispute, report the result back to you, and tell you about the commission's complaint process. If that does not resolve it, file a complaint with the Public Utility Commission of Texas — the PUCT has a customer protection division and an online complaint form. If you are served by a municipal utility or a co-op instead, your complaint goes to that city or the co-op's board, not the PUCT.
- 1. Dispute with your REP in writing — they must investigate and report back
- 2. Unresolved? File a complaint with the PUCT (customer protection division, online form)
- 3. Municipal (Austin Energy, CPS) or co-op customers: escalate to the city / co-op board
Build your evidence first
A Texas dispute is strongest when you bring the numbers: your EFL, the disputed bill, your meter reading or a photo, and a clear recalculation. Upload the bill to pull out the read type, billing period, rate, and charges automatically, so you can show the REP or the PUCT exactly where the math breaks.
Key takeaways
- Most of Texas is deregulated: you pay a Retail Electric Provider (REP), but a separate utility (the TDU — Oncor, CenterPoint, AEP Texas, TNMP) owns and reads your meter — so identify which one the error came from first.
- PUCT rule 25.480 limits backbilling: REP underbilling corrections must be billed within 180 days of the original bill, and underbilling of $50+ entitles you to a deferred payment plan of equal length.
- Dispute with your REP in writing first (they must investigate and report back); if unresolved, file a complaint with the PUCT. Austin Energy / CPS Energy and co-ops follow their own process instead.

FAQ
Who do I complain to about my Texas electricity bill — my REP or the utility?
Start with your Retail Electric Provider (REP) — the company that bills you. They must investigate the dispute and report back. If it stays unresolved, escalate to the Public Utility Commission of Texas (PUCT). Meter and delivery problems originate with your TDU, but you raise them through your REP.
How far back can a Texas provider backbill me?
Under PUCT rule 25.480, a REP generally cannot bill you for underbilled (corrected) charges unless it does so within 180 days of the original bill, and back-charges shouldn't extend more than six months before the error was discovered — with exceptions for customer meter tampering or a TDU meter-error correction.
What is an EFL and how does it help my dispute?
The Electricity Facts Label is the standardized rate sheet your REP must provide for your plan. Comparing the rate and charges on your EFL against what you were billed is the fastest way to prove a REP overcharge.
I'm with Austin Energy or CPS Energy — does this apply?
Those are municipally owned utilities and are not part of the deregulated market, so the REP/TDU split and PUCT complaint route don't apply the same way. Your dispute and complaint go through the city-owned utility's own process.
Is there a deferred payment plan if I owe a big catch-up charge?
Yes. If the underbilled amount is $50 or more, your REP must offer a deferred payment plan for the same length of time as the underbilling period, so you don't have to pay it all at once.
