Texas Electric Utilities: Oncor vs. CenterPoint vs. AEP (and How They Affect You)

When a power outage strikes or your energy bill looks off, knowing who to contact can make all the difference. For many Texans, confusion over which company handles what — and where — is common. Is it the company that sends your bill, or the one that fixes downed power lines? And how do you even know which electric provider operates in your area?

In Texas, your electricity service is split between two entities: Transmission and Distribution Utilities (TDUs) and Retail Electric Providers (REPs). TDUs like Oncor, CenterPoint, and AEP Texas manage the infrastructure — the poles, wires, and outages. REPs like Payless Power handle your billing, rates, and customer service. This separation can affect who you call in emergencies and how you choose the right electricity plan.

Understanding this structure helps you make better energy decisions, compare rates with confidence, and avoid service delays. In this guide, we’ll break down TDU service areas, explain what each type of provider does, compare Texas electric utilities, and show you how to use tools like Power to Choose — all backed by guidance from the Public Utility Commission of Texas.

Understanding TDUs and REPs in Texas

Texas operates under a deregulated electricity market, meaning consumers can choose their energy provider — but not their utility company. This setup relies on a clear split between TDUs and REPs.

Transmission and Distribution Utilities (TDUs)

Oncor, CenterPoint, and AEP Texas are responsible for delivering electricity to homes and businesses. They maintain the physical infrastructure, including power lines, transformers, and substations. They’re also the ones you contact in case of a power outage or damage to electric service lines.

Retail Electric Providers (REPs)

Payless Power or TXU sells electricity plans and manages the billing process. They determine your rate per kilowatt-hour, offer different contract lengths, and handle customer service. Your REP is who you call with questions about your electric bill or plan options.

This division ensures that, while electric providers compete on pricing and services, all customers receive the same level of infrastructure reliability from their designated distribution utility. Understanding who handles what helps Texas residents avoid confusion and get faster solutions when issues arise.

Which TDU Covers Your Area?

Your TDU depends on where you live in Texas. Here’s a breakdown of the major TDUs and the regions they serve:

• Oncor. Covers most of north and central Texas, including the Dallas–Fort Worth metroplex and surrounding areas.
• CenterPoint Energy. Serves the greater Houston area.
• AEP Texas. Operates in two main regions — the southern part of Texas, including Corpus Christi, and parts of west-central Texas, including Abilene.

At Payless Power, our prepaid electricity plans are available in areas served by these utilities: Oncor (Dallas/Fort Worth), CenterPoint (Houston), and AEP Texas (Corpus Christi and Abilene).

If you’re unsure which utility covers you, outage maps and service area tools are quick ways to confirm your provider. Most TDUs provide interactive outage maps that show coverage zones and real-time updates. These tools are especially useful during severe weather events and can be accessed via the utility company’s website.

By identifying your TDU, you’ll know who to contact for maintenance issues and can accurately compare electricity plans from available REPs within your service area.

TDU vs. REP Responsibilities: Who To Call and When

Understanding who handles what in Texas’s electricity market can save you time and frustration. Your utility company (TDU) and your energy provider (REP) play very different roles — and knowing which one to contact in different situations is key.

Here’s a quick breakdown:

• Power outage or downed lines? Call your TDU. They manage infrastructure and are responsible for restoring power.
• Questions about your electric bill? Contact your REP. They handle billing, rates, and customer service.
• Issues with delivery charges or meter readings? These are set and maintained by the TDU, but your REP is the one who relays those charges on your bill.

A common misconception is that your energy provider controls how fast outages are resolved — but that’s not the case. Every customer in a TDU’s service area gets the same restoration priority, regardless of their REP. This ensures consistent delivery quality across the board. Your energy bill reflects this split: you pay for both electricity usage and delivery charges, but only the REP portion is competitive.

Oncor vs. CenterPoint vs. AEP Texas: Quick Comparison

Here’s a side-by-side look at Texas’s three main TDUs to help you understand where they operate and how to reach them.

While each TDU covers different parts of the state, their roles remain the same. They maintain the infrastructure, restore power during outages, and pass delivery charges along to your REP — regardless of whether you use Payless Power, TXU, or another provider found on Power to Choose.

How TDUs Affect Your Electricity Plan

Your TDU doesn’t set your electric rate — but it still impacts your electricity plan. That’s because delivery charges, grid maintenance, and smart meter fees are part of your kWh cost, even though your REP does not control them.

No matter which Texas electricity provider you choose, you’ll pay the same TDU fees as everyone else in your area. These charges support the upkeep of poles, lines, and meters, helping ensure consistent and safe service. They’re bundled into your energy bill and are clearly labeled, so you can see what portion goes to infrastructure versus your provider’s rate.

In deregulated areas, customers benefit from equal access to renewable energy and service reliability because the TDU handles those physical connections. While electric companies compete on plan types and pricing, infrastructure reliability is standard across all REPs within a given service area. This makes it easier to compare rates on platforms like Power to Choose — you’re comparing apples to apples when it comes to electricity delivery.

Finding the Right REP in Your Area

Now that you know which TDU serves your region, the next step is choosing a Retail Electric Provider (REP) that fits your needs. This is where Texans have real flexibility — whether you prefer a prepaid electricity plan or a long-term contract, the market offers something for everyone.

Payless Power, for example, is a prepaid REP that offers simple, no-credit-check energy plans with flexible payment options. This makes it easier for customers who want more control over their usage and budget. On the other hand, providers like TXU offer post-pay plans that may include longer contract terms, tiered electric rates, or bundled perks.

To compare available electricity plans, Texans can use tools regulated by the Public Utility Commission of Texas (PUCT) — particularly Power to Choose, the official state comparison site. Whether you’re looking for the lowest rate per kWh, a short contract, or a renewable energy plan, this platform helps you filter for what matters most.

Choosing the right REP depends on how you prefer to manage your energy bills — whether you want upfront control with Payless Power or traditional billing with TXU. Either way, a little comparison shopping goes a long way in finding the right fit.

How to Use Power To Choose and PUCT Tools

To make an informed choice, start with Power to Choose, the state’s official electricity shopping website. This tool, overseen by the Public Utility Commission of Texas, allows users to filter plans by REP, contract length, pricing structure, and more.

Here’s how to get the most from it:

• Set your ZIP code. This ensures you’re seeing only the Texas electricity plans available in your area.
• Filter by plan type. Choose from prepaid, fixed-rate, or variable-rate options based on your needs.
• Compare contract terms. Look at plan length, early termination fees, and whether rates are promotional or stable.
• Review energy efficiency details. Some plans include renewable energy options or efficiency incentives.

You can also use the PUCT’s complaint scorecard to see how each REP ranks in customer satisfaction — a helpful tool for narrowing down trustworthy providers beyond just the cheapest electric rates.

Take Charge of Your Texas Electricity Choices

Texas’s deregulated energy system gives consumers a powerful advantage — the ability to choose a REP that aligns with their needs, budget, and lifestyle. While TDUs handle outages and infrastructure, energy providers manage your plan, rates, and electric bill.

By understanding this division, Texans can respond to a power outage more effectively, identify their correct service area, and shop smarter for better electric rates. Tools like Power to Choose and resources from the Public Utility Commission of Texas make it easier than ever to evaluate your options.

Whether you’re looking for flexibility, low rates, or simplicity, there’s a REP out there for you — and Payless Power makes it easy to get started.

FAQ About Texas Electric Utilities

Still have questions about how Texas electricity works? You’re not alone. These quick answers address common concerns Texans have about electric companies, billing, and the roles of major players like CenterPoint and TXU.

How many electric utilities are there in Texas?

Texas has five main utility companies (TDUs) that manage electricity delivery in deregulated areas. These include Oncor, CenterPoint, AEP Texas, Texas-New Mexico Power, and Sharyland Utilities. Most Texans fall under one of these depending on their location.

Who has the cheapest electricity rates in Texas?

No single electric provider always has the lowest rate. Use Power to Choose to compare electric service options by ZIP code. Rates vary based on contract length, usage habits, and plan type — prepaid REPs like Payless Power can offer competitive pricing for budget-conscious customers.

Which electricity provider in Texas?

Texas residents can choose from dozens of electric companies in deregulated areas. Popular energy providers include Payless Power, TXU, Reliant, and Direct Energy. The best REP for you depends on your usage patterns, contract preferences, and billing style.

Is CenterPoint the only energy company in Texas?

No. CenterPoint is a utility company, not a REP. It handles infrastructure in the Houston area but does not sell electricity plans. Texans in CenterPoint’s service area can choose from many electric providers for their energy plan.

Is TXU owned by CenterPoint?

No, TXU and CenterPoint are separate companies. TXU is a Retail Electric Provider, while CenterPoint is a utility company that manages power delivery. They operate independently and serve different roles in the electricity system.

How can I lower my bill with CenterPoint Energy?

Since CenterPoint doesn’t set electricity rates, switching REPs won’t change your delivery charges. To lower your energy bill, shop for a more affordable electric provider, reduce energy use, or consider a prepaid plan for better budget control.
