How to pay your Killeen utility bill depends on which company supplies your power
Killeen is served by two main electric suppliers: Oncor Electric Delivery, which handles the wires and poles in most of the city, and Brazos Electric Power Cooperative, which serves some areas. Your bill will show which one delivers to your address. The company you pay is often different from the one that delivers the power — your retail electric provider (REP) buys the electricity and bills you, while the delivery company maintains the lines.
Most Killeen residents can pay online, by phone, by mail, or in person. The exact payment methods depend on which REP you use. If you don't know your supplier, check your bill — it will list the company name and their payment instructions on the front or back.
The fastest way to find your supplier and payment options is to call Oncor's customer service at 1-888-313-4747 and ask which REP serves your address. Oncor can also tell you if you are in a deregulated area where you can choose your supplier, or if you are locked into a single provider.
Key Takeaways
- Your bill shows both your delivery company (Oncor or Brazos) and your retail electric provider, and you pay the retail provider, not the delivery company.
- Most Killeen REPs accept online payments through their website, phone payments by calling the number on your bill, and mail payments to the address listed on your statement.
- Oncor's customer service line (1-888-313-4747) can tell you which REP serves your address and whether you can switch suppliers.
- If you are behind on your bill, contact your REP directly to ask about payment plans or hardship programs before the account is disconnected.
- Your bill will show the due date, late fees, and disconnection timeline, so read it carefully to avoid surprise charges.
Finding your retail electric provider and their payment website
Your bill lists your REP's name and website at the top or in the account information section. Common REPs in Killeen include Reliant, TXU Energy, Gexa Energy, and others, though the list changes as companies merge or exit the market. Go to your REP's website and look for a "Pay My Bill" or "Account" link — most allow you to set up an online account using your account number and zip code.
If you have lost your bill or cannot find the REP name, call Oncor at 1-888-313-4747 with your address or account number. They will tell you which REP is billing you. Once you have the name, search the company online and look for their customer service phone number — it is usually on the first page of results.
Some REPs offer automatic payment (autopay) through your bank account or credit card. This is optional, but it prevents late payments if you forget the due date. You can usually set it up on the website or by calling customer service.
Payment methods: online, phone, mail, and in-person options
Most Killeen REPs accept online payments through their website at no extra charge. You will need your account number (on your bill) and a bank account or credit card. The payment usually posts within one business day, though some companies charge a fee if you pay by credit card instead of bank transfer.
Phone payments are available from nearly all REPs. Call the number on your bill and follow the prompts to pay by debit card, credit card, or bank account. Some companies charge a small fee for phone payments, so ask before you confirm. Phone payments often go through the same day if you call before 5 p.m. on a business day.
Mail payments take 7 to 10 days to reach the company, so send them at least two weeks before the due date. Write your account number on the check or money order and mail it to the address on your bill. Do not send cash by mail.
A few REPs have payment centers or partner locations in Killeen where you can pay in person with cash, check, or card. Call your REP to ask if they have a local payment location, or check their website for a "Payment Locations" or "Pay in Person" page.
What to do if your bill is overdue or you cannot pay on time
If your bill is past due, contact your REP immediately — do not wait for a disconnection notice. Most companies offer payment plans that let you split what you owe into smaller monthly payments over 3 to 12 months. You will usually need to pay a portion of the overdue amount right away and then add the rest to your next few bills.
Ask your REP about hardship programs if you are struggling with the cost. Some companies have programs for low-income households, seniors, or people facing a temporary crisis. These programs may lower your bill, offer a payment plan with no extra fees, or provide one-time help. The programs vary by company, so call and ask what is available.
If you cannot reach an agreement with your REP, contact the Public Utility Commission of Texas (PUC) at 1-888-782-8477. The PUC oversees electric companies in Texas and can investigate complaints about billing or disconnection. You can also file a complaint online at the PUC website.
Disconnection usually happens 20 to 30 days after the due date, but the exact timeline is on your bill. Once the power is cut, reconnection fees apply (typically $50 to $150), so paying or setting up a plan before that date saves money.
Understanding your bill: charges, rates, and how to spot errors
Your Killeen bill has three main parts: the energy charge (the cost of the electricity you used), the delivery charge (paid to Oncor or Brazos for maintaining the lines), and taxes and fees. The energy charge is what changes month to month based on how much you use. The delivery charge is usually fixed or changes slowly.
Your bill shows your usage in kilowatt-hours (kWh). If you used 800 kWh last month and your rate is 12 cents per kWh, your energy charge is about $96 before taxes. Check that the usage number makes sense — if it is much higher than usual, you may have a leak or appliance problem, or the meter may have been misread.
Look for late fees, reconnection fees, or other charges you do not recognize. If you see something wrong, call your REP and ask them to explain it. If you believe the charge is an error, ask for a meter reread or a bill adjustment. The company must investigate within 30 days under Texas law.
Switching suppliers if you are in a deregulated area
Some parts of Killeen are in a deregulated market, which means you can choose your REP instead of being assigned one. Oncor will tell you on the phone whether your address is in a deregulated area. If it is, you can compare rates and switch to a different company.
To switch, visit the PUC's Retail Electric Provider Directory at powertomerchoose.org. Enter your zip code to see all REPs available in your area, their rates, contract terms, and customer reviews. Compare the price per kWh and any fixed-rate or variable-rate options. Some companies offer lower rates for 12 months, while others have rates that change monthly.
Once you pick a new REP, you can switch online through their website or by calling them. The switch usually takes 10 to 21 days. Your old REP will send a final bill, and your new REP will start billing you. You do not need to do anything with Oncor or Brazos — the delivery company stays the same.
If you are not in a deregulated area, you are served by a single REP and cannot switch. In that case, focus on reducing usage to lower your bill — see the next section for tips.
Reducing your bill: practical steps that work
The easiest way to lower your bill is to use less electricity. In Killeen's hot climate, air conditioning is usually the biggest cost. Set your thermostat to 78°F when you are home and 82°F or higher when you are away. Each degree higher saves about 3% on cooling costs. Use a programmable or smart thermostat to automate this.
Other high-cost appliances are water heaters, refrigerators, and clothes dryers. Take shorter showers, wash clothes in cold water, and air-dry when possible. Keep your refrigerator coils clean and make sure the door seals tightly. Unplug devices that draw power even when off, like phone chargers and coffee makers.
Ask your REP if they offer a budget billing plan, which spreads your costs evenly across 12 months so your bill is the same each month. This helps you plan ahead, though you may owe money at the end of the year if you used less than expected.
Some REPs offer time-of-use rates, where electricity costs less during off-peak hours (usually late evening and early morning). If your rate plan allows it, run dishwashers, laundry, and pool pumps during these cheaper hours.
Frequently Asked Questions
How do I find out which company is my electric provider?
Look at your electric bill — your retail electric provider's name and logo are at the top. If you cannot find your bill, call Oncor at 1-888-313-4747 with your address or account number, and they will tell you which company bills you.
Can I pay my Killeen electric bill in person with cash?
Some REPs have local payment locations or partner stores where you can pay in cash, but not all. Call your REP's customer service number (on your bill) and ask if they have a payment center in Killeen. If not, you can pay online or by phone with a debit card.
What happens if I miss my due date?
Late fees are added to your bill, usually 1% to 2% of what you owe. Disconnection typically happens 20 to 30 days after the due date. Call your REP before that date to set up a payment plan and avoid losing power.
Is my address in a deregulated area where I can choose my supplier?
Call Oncor at 1-888-313-4747 and ask. If you are in a deregulated area, you can compare rates at powertomerchoose.org and switch to a different REP. If not, you are locked into your current supplier.
How long does it take to switch electric companies?
The switch usually takes 10 to 21 days from the date you request it. Your old company will send a final bill, and your new company will start billing you. You do not need to contact Oncor or Brazos — the delivery company does not change.
