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:

ComponentWho Sets ItWhat It Covers
Energy ChargesYour REP (Retail Electric Provider)Per-kWh rate for electricity used
Delivery ChargesYour 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 TypeHow Rate Works
Fixed-rateConsistent rate throughout contract
VariableFluctuates monthly with market
TieredRate 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.

TDUDelivery 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.

Hidden Fees and Taxes to Watch For

Beyond energy and delivery charges, Texas electric bills often include additional fees:

Fee TypeAmountWhat It Is
Base/Customer Charge$5-15/monthFixed amount regardless of usage
Early Termination FeeVariesPenalty for switching before contract ends
REC CostsVariesAppears on green plans
State/Local Taxes6-8%Added to total bill
System Benefit FundSmall feeSupports low-income assistance programs

Always check your EFL for minimum usage fees or bill credits that affect actual cost at different usage levels.
