Killeen electric companies: 44 compared, real rates and move-in help

Two companies are part of every Killeen power bill. Oncor owns the poles, wires and meters, and it fixes outages. The retail company you pick buys the power, sets your price and sends the bill.

Oncor’s tariff names Killeen, Harker Heights, Copperas Cove, Nolanville, Belton, Temple and Salado among the cities it serves. Picking a new company never changes who climbs the pole after a storm. Not sure who serves your home? Our guide to finding your electric utility shows where to look on a bill.

Look at each company’s complaint rating from the state first. Then type the kWh from your bill, and every company’s simplest 12-month plan gets re-priced for you.

Some licensed sellers had no plans posted for Oncor’s area on Oct 16, 2026. Vistra’s 4Change Energy and Ambit were two of them. So were NRG’s XOOM Energy and Stream, Genie’s Town Square Energy, Tesla Electric, Shell Energy Solutions and Energywell. They can still sell to you on their own websites. Check our 4Change Energy review or Ambit Energy review first, or scan the full list of Texas electricity companies.

On Oct 16, 2026, simple 12-month plans in Killeen ran from 12.0¢ to 16.1¢ per kWh at 1,000 kWh. That puts the cheapest at about $120 a month and the middle plan at about $132. Both prices already include Oncor’s delivery charge.

What’s the average electric bill in Killeen?

No public source tracks a Killeen-only average. The closest number is for all of Texas: $163.72 a month for 1,096 kWh in 2024, per the U.S. Energy Information Administration. At Oct 16, 2026 prices, that much power would cost about $132 on Killeen’s cheapest simple plan, or about $145 on the middle one. Those are our estimates, before taxes. See how yours compares in our average Texas electric bill guide.

Already on a plan? On Oct 16, 2026, 140 of the 174 plans for Oncor’s area were for new customers only, so your company may not offer you its best price. Here’s what to do when your contract ends.

Killeen is a town of movers. A state rule lets you leave a power plan with no cancel fee when you move out. And a few steps get your lights on before the moving truck shows up.

ZIP 76544 figures are Census estimates for 2020 to 2024 with wide margins, about 4 points either way. For Killeen as a whole, 22.9% moved in a year, against 14.0% for Texas.

Texas utility law (PURA) has no separate exit right just for service members, so this moving rule is the one to use. Want the full picture on fees? See contract endings and exit fees.

Can you skip the deposit?

• The state rule is narrow. It names only people 65 or older and certified victims of family violence. Companies may add their own ways.
• One military waiver. Chariot Energy says active-duty customers may qualify with deployment orders or a letter from their command. That’s its own policy, not a state right. The PUCT’s Sept. 2026 scorecard puts Chariot in its highest complaint group, 1 of 5 (complaints filed, not findings). We score it 64.
• More ways out. Our no-deposit electricity guide lists six free ways to avoid one.

Your Killeen move-in checklist

1. 1
   In-process first

   Soldiers must in-process with Fort Hood’s Housing Services Office before they rent, lease or buy a home in the area, Military OneSource says.

2. 2
   Find the ESI ID

   Type your new address into Oncor’s ESI ID lookup. Your new company needs this number to start service.

3. 3
   Pick a plan and a start date

   Shop before move-in day. Oncor bills your company $0.55 to turn on an existing meter, or $25.30 on a holiday. Your plan terms say if you pay it.

4. 4
   Start water on its own

   The City of Killeen runs water and sewer, not power. Its standard deposit is $90. Call 254-501-7800, Monday to Thursday, 7 a.m. to 6 p.m.

5. 5
   Leaving? Send your new address

   Give your company your move-out date and forwarding address, and keep proof. Then the state rule blocks the cancel fee.

Moving in fast? See same-day electricity cut-off times and our 4-step setup guide. Moving within Killeen? The city lets water stay on at both homes for up to 7 days. Living on post? Ask the housing office if power comes with your rent before you buy a plan. We couldn’t confirm how on-post homes are billed.

Yes. On Oct 16, 2026, every Killeen-area ZIP with plans showed the same Oncor list. That takes in Harker Heights, Copperas Cove, Nolanville, Fort Hood, Belton, Salado and Kempner. What changes from town to town is the homes.

• Nolanville is growing fastest. Census estimates it grew 34.8% from 2020 to July 2025, to 7,983 people. Half its homes were built in 2007 or later.
• Copperas Cove has more gas heat. About 22% of its homes heat with utility gas, against under 8% in Killeen. Gas-heated homes lean less on power in winter.
• Most of ZIP 76522 sits outside Copperas Cove. Only 15% of its land is inside city limits, and it spans Coryell and Lampasas counties. Rural addresses there should use the ZIP check below.
• Harker Heights spills into 76513. About 16% of the city’s land lies in a ZIP labeled Belton.

Comparing towns on the same Oncor lines? Our Waco electricity guide covers the next big city up the road, and the Round Rock guide covers the Austin side.

Homes on a co-op or a city-owned utility can’t shop for power. Around Killeen, that mostly means rural land at the edges and a few nearby towns. A ZIP check is a good start, but the name on your bill decides.

• The ESI ID settles it. On a bill or lease papers, an ESI ID that starts with 1044372 means Oncor. One that starts with 1040051 means TNMP.
• Gatesville mixes two lines. Its ZIP lists plans for both Oncor and TNMP, so prices depend on the address. See our TNMP guide.
• Three Killeen ZIPs list nothing. 76545, 76546 and 76547 show no plans, and Census files list no ZIP area for them. That fits P.O. box ZIPs, so use the ZIP where you live.

Killeen has two seasons that spin the meter. Summer brings about 105 days a year at 90°F or hotter. And nearly 9 in 10 Killeen homes heat with electricity, so cold months count too.

Next to Dallas–Fort Worth, Killeen needs about 5% less cooling over a year: 2,682.5 cooling degree-days against 2,824. Its winter need is real, though. January alone logs about 536 heating degree-days, more than June’s 478 for cooling. Want to see your own month-by-month use? Our Smart Meter Texas guide shows how to pull it.

Big summer bills have more causes than price. Our guide to why an electric bill runs high walks through them, and the bill-credit plan guide shows how a credit can vanish.

It depends on your usage and what you care about. Each pick uses the state’s complaint ratings, fact-label prices from Oct 16, 2026 and our scores. No company paid to be in our table, picks or scores.

Call Oncor for outages and downed lines. Call your electric company about bills, plans and moves. Changing companies never changes the crew that fixes your power.

Storms Oncor has called out in Killeen

• February 2021, ice storm. Oncor said ice coated its southern region, which takes in Killeen, Round Rock and Temple. On the morning of Feb 19, about 72,000 customers in that region and its eastern region were still out.
• October 2021, wind storm. Oncor named Killeen among the towns hit. At one point, more than 115,000 customers across its system were without power.
• February 2023, ice storm. Oncor said the Round Rock, Taylor, Temple and Killeen areas got some of the heaviest ice.

Oncor says it sees about 31 major storms a year somewhere in its area. Our guide to what to do when the power goes out has the steps.

Need help paying a Killeen bill?

• Texas 211: call 1-877-541-7905, or just dial 211, to find aid near you.
• Hill Country Community Action Association: 1-325-372-5167. It runs the state’s energy aid program for Bell, Coryell and Lampasas counties.

Money can run out, and no program promises help. More options are in help paying an electric bill in Texas.

Each check uses a document the company has to give you, or a public record.

1. 1
   Price it at 500 and 2,000 kWh

   Killeen bills swing with heat and cold. A plan that looks cheap at 1,000 kWh can cost far more in a light month.

2. 2
   Look for a bill credit

   A big price drop right at 1,000 kWh means a credit props it up. Use less in a mild month, and the credit can vanish.

3. 3
   Check the label’s date

   Oncor raised delivery on Oct 4, 2026. Ask for a fact label dated that day or later.

4. 4
   Know the exit fee type

   Some plans charge one flat fee, like $150 or $300. Others charge $20 for each month left. A move doesn’t count if you give a forwarding address.

5. 5
   Know your 3 days

   Switching from another company? You get 3 federal business days to cancel for free. Starting power at a new home doesn’t come with that window.
