Many Texans shopping for power on the power to choose portal are surprised when they sign up for an eco-friendly plan with a top-tier provider like Gexa Energy, only to see a utility truck from Oncor or CenterPoint parked outside their home. Why are two different entities involved in powering your home? The answer lies in the unique structure of the deregulated Texas grid, where the company that sells you electricity is entirely separate from the company that owns and maintains the physical power lines. Understanding how these entities interact is key to making sense of your monthly utility statement.
Understanding the Difference: Retail Electric Providers vs. TDSPs
In Texas, the electricity market is split into two primary roles: Retail Electric Providers (REPs) and Transmission and Distribution Service Providers (TDSPs, also known as TDUs). Your REP is the customer-facing company that purchases wholesale electricity, designs plan options, and manages your billing. Whether you are looking for residential electricity Houston residents trust or electricity dallas neighborhoods rely on, your retail provider acts as your energy retailer.
On the other hand, your TDSP is the utility company that actually delivers the physical electricity to your home. They own the poles, wires, and smart meters, and they are responsible for fixing power outages and maintaining grid infrastructure. Regardless of which REP you select, your physical utility is determined solely by your geographic location. The six major TDSPs servicing the ERCOT grid include Oncor, CenterPoint Energy, AEP Texas Central, AEP Texas North, Texas New-Mexico Power (TNMP), and the newly deregulated Lubbock Power & Light (LP&L).
Having texas tdsp delivery charges explained: What Are Pass-Through Fees?
When you look at your monthly electricity statement, you will notice a section dedicated to TDSP delivery charges. These are regulated pass-through fees approved by the Public Utility Commission of Texas (PUCT). Because your REP must pay the local utility for using their physical wires to deliver electricity to your home, these costs are passed directly to you without any markup from the retail provider.
These delivery charges consist of two main components: a fixed monthly utility charge and a volumetric charge based on your total cost per kilowatt-hour of usage. Because these fees are set by the PUCT and go directly to the utility company, they remain identical no matter which retail provider you choose. This means that even if you switch REPs to get a better supply rate, your local TDSP delivery charges will remain exactly the same.
Why Pass-Through Charges Apply to Renewable Energy Plans
A common point of confusion for eco-conscious consumers involves how green energy plans interact with utility charges. For instance, if you choose the popular Gexa Eco Saver Plus 12 Plan, Gexa Energy ensures that 100% of your electricity usage is offset by purchasing and retiring renewable energy credits (RECs) for a full year. This is a fantastic way to support clean energy development and reduce your carbon footprint.
However, even though Gexa Energy offsets your usage with green energy, the physical electrons generated by wind farms and solar arrays must still travel across the physical grid. Your local TDSP is still the entity that maintains the physical wires carrying those electrons to your home. Because the physical delivery infrastructure is identical regardless of the source of your power, TDSP delivery charges apply to green energy plans in the exact same manner as they do to standard fossil-fuel plans.

Frequently Asked Questions (FAQ)
What is the difference between a REP and a TDSP?
A Retail Electric Provider (REP) is the company that sells you electricity plans, manages your account, and bills you. A Transmission and Distribution Service Provider (TDSP) is the physical utility company that maintains the electrical grid, wires, and poles, and responds to power outages in your area.
Are TDSP delivery charges the same across all of Texas?
No. TDSP delivery charges are determined by your geographic location and are regulated by the PUCT. Each of the six major Texas utility companies has its own approved rate schedule, meaning your delivery charges will vary depending on whether you live in an area serviced by Oncor, CenterPoint, TNMP, LP&L, or AEP.
Do I still have to pay TDSP charges if I switch to a 100% green energy plan?
Yes. Even if you choose an eco-friendly plan that offsets your usage with 100% renewable energy credits, your physical electricity is still delivered to your home via the local utility’s poles and wires. Therefore, the standard TDSP pass-through delivery fees will still apply to your monthly statement.
