TDSP Delivery Charge Increases: What Texas Electricity Shoppers Should Check in 2026

Texas electricity shoppers often focus on the retail provider name, but delivery charges can move the bill even when the provider does not change. TDSPs, also called TDUs, maintain the local poles, wires, meters, and delivery system. When delivery charges rise, the advertised energy rate is only part of the story.

Quick answer

If TDSP delivery charges increase, compare the all-in bill instead of only the retail energy rate. Check the EFL for whether delivery charges are included in the average price, then model the plan at your real usage. Oncor, CenterPoint, AEP Texas, and TNMP territories can produce different delivery-charge impacts.

What is a TDSP/TDU?

A TDSP is the utility delivery company for your address. It is separate from the retail electricity provider you choose. In much of Dallas-Fort Worth the TDSP is Oncor. In much of Houston it is CenterPoint. Other Texas addresses may use AEP Texas or TNMP.

How delivery increases change plan choice

• A low retail energy rate can be offset by higher delivery charges.
• Bill credits may hide the effect at one usage level but fail at another.
• High-usage homes feel per-kWh delivery changes more strongly.
• Apartment and low-usage customers may feel fixed monthly charges more sharply.

Betterplan recommendation

Every local page should explain the utility/provider split. That helps shoppers understand outages, delivery charges, and why two households with different addresses can see different plan economics even when the retail provider brand is the same.
