Quick Answer
Learn what every charge on your Texas electricity bill means and how to spot overcharges.
How Texas Electric Bills Are Structured
Texas electricity bills have two main components:
| Component | Who Sets It | What It Covers |
|---|---|---|
| Energy Charges | Your REP (Retail Electric Provider) | Per-kWh rate for electricity used |
| Delivery Charges | Your TDU (Transmission & Distribution) | Infrastructure that delivers power |
Key differences:
- TDU charges are regulated by PUCT and vary by service territory
- REP rates are competitive and negotiable through shopping
- Most bills also include state/local taxes (typically 6-8%)
Understanding Energy Charges
Energy charges represent what you pay your REP for electricity consumed—a per-kWh rate × your monthly usage.
| Plan Type | How Rate Works |
|---|---|
| Fixed-rate | Consistent rate throughout contract |
| Variable | Fluctuates monthly with market |
| Tiered | Rate changes at usage thresholds (often 1,000 or 2,000 kWh) |
Watch out for:
- "Energy charges" that bundle base rate + hidden fees
- Low advertised rates that exclude fees appearing separately on your bill
The EFL (Electricity Facts Label) breaks down exactly what's included in advertised rates.
TDU Delivery Charges on Your Bill
TDU delivery charges cover infrastructure maintenance, meter reading, and power distribution. These charges are identical regardless of which REP you choose.
| TDU | Delivery Rate |
|---|---|
| Oncor | ~3.5¢/kWh |
| CenterPoint | ~4.2¢/kWh |
| AEP Texas | ~4.0¢/kWh |
How they appear:
- Separate line items, OR
- Bundled into "all-in" total rate
Pro tip: When comparing plans, always add TDU charges to base rate for accurate cost comparison. TDU charges also include small state-mandated fees for renewable energy and low-income assistance.
