Texas has one of the biggest deregulated electricity markets in the country. Because of this, most residents work with two companies for their electricity. One company delivers the electricity to your home, while the other sells you the electricity and sets your rate.
Knowing who does what is especially important if the lights go out, you want an energy plan with different features, or you don’t understand why your bill is higher this month.
Let’s look at the difference between utility companies and retail energy providers (REPs) in Texas, including who handles outages, billing, and pricing, plus how to make smarter choices as a Texas electricity customer.
Utility vs. Retail Provider: Side-by-Side Comparison
Once you know which role belongs to which company, it’s much easier to troubleshoot issues and compare offers. The chart below summarizes the difference between the two.
| Category | Utility Company | Retail Energy Provider |
| Owns power lines | Yes | No |
| Restores outages | Yes | No |
| Sends monthly bill | No | Yes |
| Sets electricity rate | No | Yes |
| Choice varies by provider | No | Yes |
The simplest way to think about it is that the utility is the “delivery system,” and the REP is the “pricing and service layer” you can shop for.
Plans that Fit Your Needs
Whether you're at home or running a business, find electricity plans designed to fit your needs.
What Is a Utility Company?
In Texas, your utility company is the organization that owns and maintains the “wires” infrastructure — the poles, power lines, transformers, and local equipment that physically deliver electricity to your home. Utilities don’t compete for your business in the same way REPs do.
Instead, they’re assigned to specific areas with oversight governing how they maintain the grid and the delivery fees they can charge. That’s why you can’t “switch utilities” the way you can switch electricity plans. Your utility provider depends on where you live.
If your neighborhood is served by Oncor, for example, Oncor is the company responsible for maintaining the lines and restoring service when equipment fails — regardless of which REP you buy power from.
Examples of utility companies in Texas include:
Who do you call for a power outage?
Call your utility company if the power goes out. Utilities have the crews and systems needed to restore service. They fix downed lines, damaged transformers, and handle other grid problems like city-wide blackouts.
Your REP can answer billing and plan questions, but it typically can’t fix an outage or dispatch repair crews.
A good rule of thumb: if the problem is “my lights are off,” start with the utility. If the problem is “something’s wrong with my bill,” start with the REP.
What Is a Retail Energy Provider (REP)?
A retail energy provider (REP) is the company you choose to buy electricity from in deregulated parts of Texas. REPs do not own the poles and wires. They buy electricity on the wholesale market, create different plans, and sell them to customers with various pricing and contract options.
This is the company that sets the energy rate you see advertised, sends your monthly bill, and provides your plan terms, including whether you’re on a fixed rate, a variable rate, a time-of-use plan, or a renewable energy option. You can shop for, compare plans and EFLs, and switch providers depending on what’s most important to you.
People tend to confuse the companies because even though you choose the REP, the electricity still flows over the same utility-managed infrastructure. However, if a storm knocks out power lines, your REP can’t fix them.
Here are just some of the energy providers in Texas:
- Amigo Energy
- BKV Energy
- Constellation
- GoodCharlie
- Just Energy
- Payless Power
- Reliant Energy
- Tara Energy
- TXU Energy

Why Texas Allows You to Choose Your Retail Energy Provider
Texas deregulated much of its electricity market in 2002, separating the physical delivery of power from the sale of electricity supply. The goal was to create competition among retail providers, giving consumers more options — and, in theory, putting downward pressure on prices over time.
In a regulated market, you typically buy electricity from a single utility at rates approved through a regulatory process. In deregulated Texas, consumers can shop among many REPs, each offering different pricing models, contract lengths, and features. That’s what makes it possible to choose between:
- Fixed-rate vs. variable-rate plans, depending on whether you want stability or flexibility
- Renewable energy plans, including options supported by renewable energy certificates (RECs)
- No-deposit or prepaid options, which may be helpful for customers who want to avoid credit checks or upfront costs

How Utility Charges Still Affect Your Bill
Even if you lock in a low electricity rate through a retail energy provider, that rate is only part of your total monthly cost. Utility charges, often listed as transmission and distribution utility (TDU) fees, are added to your bill regardless of which REP you choose.
These charges typically cover:
- Maintenance of power lines, meters, poles, and transformers
- Day-to-day operation of the local delivery network
- Grid reliability upgrades and storm restoration work
Because utility companies are regulated, TDU charges:
- Are the same for all customers in the same service area
- Do not change when you switch retail energy providers.
- Cannot be negotiated or avoided through plan shopping
This is why your energy bill can feel counterintuitive. Your REP’s energy rate may drop, but your total bill may not fall as much, or at all, if utility charges increase at the same time. Utility charges don’t change as often as REPs, though, as they’re regulated by the Public Utility Commission of Texas (PUCT).
How EnergySavings.com Helps You Compare Retail Energy Providers
Shopping for electricity in Texas isn’t just about finding the lowest price. You also want a plan that fits your real-life usage and doesn’t have hidden surprises in the fine print.
EnergySavings.com helps simplify that process by offering transparent plan comparisons and practical filters that let you narrow options based on what matters most to your household. Instead of scanning dozens of plans manually, you can filter by:
- Contract length (short-term flexibility vs. longer-term price stability)
- Green energy options
- No-deposit plans
- Usage level (so you’re not comparing plans designed for completely different consumption patterns)
This approach matters because the “best” plan isn’t universal. A household with high summer air-conditioning demand may prioritize price stability and a strong fixed rate. A renter who expects to move soon may care more about shorter terms and fewer penalties. The right comparison tool helps you make decisions that fit your lifestyle, not just the marketing headline.
FAQ About Utility Companies and REPs
Who regulates utility companies and retail energy providers in Texas?
The Public Utility Commission (PUC) oversees both utility companies and retail energy providers in Texas. ERCOT runs the state’s power grid and wholesale electricity market, ensuring the system remains reliable. However, doesn’t set the prices consumers pay.
Does switching retail energy providers affect who services my home or responds during storms?
No. Your utility company stays the same because it’s based on where you live, not which REP you choose. Switching REPs changes your electricity pricing and plan terms, not who restores power after storms.
Why do utility charges stay the same even when electricity rates drop?
Utility delivery charges are regulated fees tied to maintaining the grid, not the wholesale cost of electricity supply. Even if REP energy rates fall, TDU charges may stay flat or rise depending on utility-approved updates.

Final Takeaway: Two Roles, One Electricity Bill
In deregulated Texas, utilities and REPs play two distinct roles in the same electricity experience. The utility company delivers power, maintains the grid, and restores service during outages. Your retail energy provider sets your electricity rate, sends your monthly bill, and offers the plan options you can shop for.
If you want more control over costs, the biggest lever you can pull is choosing the right REP while keeping in mind that utility delivery charges will always be part of your total bill.
