Electricity billing in Texas's deregulated market involves multiple parties. Understanding how Oncor, your retail electricity provider, and ERCOT work together helps you manage your account and resolve issues.
The Players
Several entities are involved in your electricity service:
- Oncor (TDU): Owns the wires, delivers electricity, reads your meter
- Your REP: Sells you electricity, sends your bill, handles customer service
- ERCOT: Manages the Texas grid and wholesale market
- Power generators: Produce the electricity you use
Billing Cycle
Your billing cycle works like this:
- Oncor reads your meter (usually via smart meter)
- Oncor sends usage data to your REP
- Your REP calculates your bill based on your plan
- Your REP sends you a combined bill (energy + TDU charges)
- You pay your REP, who pays Oncor for TDU charges
Payment Options
Most REPs offer several payment methods:
- Automatic bank payment (autopay)
- Online payment via REP website
- Phone payment
- Mail-in check
- In-person at authorized locations
Some REPs offer average billing to spread costs evenly across the year.
Managing Your Account
Keep track of your contract end date to avoid month-to-month rates. Most REPs send renewal notices, but it's your responsibility to shop for a new plan before your contract expires. Set a calendar reminder 2-4 weeks before your contract ends.
