Killeen TX Electricity Plans: Compare Real Cost at 500 and 2000 kWh
If you live in Killeen and you're staring at a wall of electricity plans, the numbers that matter most are probably not the ones in big bold type on the shopping site. Texas law requires every retail plan to publish three average prices—at 500, 1,000, and 2,000 kilowatt-hours (kWh) per month—but those figures are easy to misread. A plan that looks cheapest at 1,000 kWh can be one of the most expensive options for a one-bedroom apartment using 500 kWh, or for a four-bedroom house running the AC hard at 2,000 kWh.
This guide walks Killeen residents and small-business owners through how to compare plans at the usage levels that actually match their homes, why the same contract produces different real costs at 500 versus 2,000 kWh, and where to shop without getting tripped up by bill credits, minimum-usage fees, and teaser rates.
Killeen sits in Texas's competitive electricity market
Killeen is in Bell County, part of the ERCOT grid that covers most of Texas. Since the Texas Legislature passed electric deregulation in 1999, many Texans—including most residents in the Killeen area—choose a retail electric provider (REP) for the supply portion of the bill while a separate transmission and distribution utility (TDU) continues to deliver power over local wires, read the meter, and restore outages (¹). Senate Bill 7 in the 76th Texas legislative session established the framework for that restructuring (²).
That split matters when you compare prices. Your REP sets the energy charge and any plan-specific fees. Your TDU sets regulated delivery charges that pass through on every bill, regardless of which REP you pick. Power to Choose, operated by the Public Utility Commission of Texas, lists certified REPs and links each plan to an Electricity Facts Label (EFL) so you can compare offers side by side (³).
To see plans available at your address, enter your Killeen ZIP code on Power to Choose. If more than one TDU serves that ZIP, the site will ask you to pick the correct one before showing results (⁴). Texas TDUs include Oncor, CenterPoint Energy, AEP Texas, Texas-New Mexico Power, and others; outage and wire-service contacts are listed on the ⁵ published by the Public Utility Commission.
Switching REPs does not interrupt service. The local wires company stays the same, and a new contract typically takes effect within seven business days after you confirm (¹). ERCOT sends a confirmation mailer when you switch, with details on how to cancel within three business days (¹).
Why 500 kWh and 2,000 kWh are the right comparison points
Texas plan marketing revolves around three usage tiers: 500, 1,000, and 2,000 kWh per month. Those are not random benchmarks. They approximate low, middle, and high residential use patterns—and they expose how fixed monthly charges distort your true price per kWh.
500 kWh is the realistic zone for many Killeen apartments, smaller units, single occupants, or households that keep usage tight through mild spring and fall months. 2,000 kWh is closer to what a larger home hits when Central Texas heat drives air conditioning for much of the day—especially June through September.
Statewide data helps frame expectations. Texas households use more electricity than the U.S. average, largely because of cooling demand: EIA's Residential Energy Consumption Survey found average Texas home electricity use at about 16,000 kWh per year—roughly 1,330 kWh per month—with air conditioning accounting for a larger share of home energy than in most other states (⁶). Over 80% of Texas homes use central air conditioning, according to the same survey. That average is a midpoint, not a target. Your month can land far below it in April or far above it in August.
If you are near 500 kWh, sorting plans by the 1,000 kWh average price can steer you wrong. If you routinely exceed 1,500–2,000 kWh in summer, the 500 kWh column is irrelevant except as a warning: some plans penalize low use. Power to Choose's user guide explicitly recommends calculating your estimated average monthly usage from past bills before you filter results (⁴).
Seasonal swings matter in Central Texas
Killeen sits in the southern end of the Great Plains with hot summers and mild winters relative to northern states. EIA notes that in Texas and neighboring states, air conditioning accounts for about 18% of home energy use while space heating accounts for a smaller share than in colder climates (⁶). Practically, that means many households have months near 500 kWh in spring and fall but approach or exceed 2,000 kWh when the AC runs flat out.
That seasonal spread is why comparing only a single month—or only the 1,000 kWh tier—can mis-rank plans. A bill credit that triggers above 1,000 kWh helps you in July but not in April. A minimum usage fee hurts you in April but disappears in July. Run the comparison at both 500 and 2,000 kWh to see which plan stays competitive across your range.
Read the Electricity Facts Label, not just the headline rate
Every Texas retail plan must provide an Electricity Facts Label (EFL)—a standardized fact sheet with contract length, renewable content, fees, and the three average prices at 500, 1,000, and 2,000 kWh (⁷). The EFL also breaks out:
- Energy charge — cents per kWh from your REP (fixed or variable depending on plan type)
- Base charge — a flat monthly fee from the REP, if any
- TDU/TDSP delivery charges — regulated pass-through fees from your wires company
- Bill credits or minimum usage fees — adjustments tied to how much you use in a billing cycle
When comparing plans, confirm that the average prices you are reading reflect all-in costs. The PUC's shopping checklist asks whether a quoted rate includes electricity, transmission and distribution charges, and any recurring monthly fees (⁸). The EFL is designed for apples-to-apples comparison—but only if your actual usage is close to the tier you're reading.
When calling a REP, the PUC suggests asking whether a quoted rate includes everything: energy, transmission and distribution, and recurring monthly fees (⁸). Question two on the PUC checklist is explicit: "Does this rate include everything, including the electricity cost, the transmission and distribution charges, as well as any monthly customer charges or other recurring fees?"
Plan types shape risk:
- Fixed-rate plans lock the energy charge for the contract term, with limited exceptions for TDU fee changes or regulatory updates (⁷).
- Variable and indexed plans can change monthly, which makes the 500/1,000/2,000 snapshots a moment-in-time estimate rather than a guarantee (⁷).
Why one plan looks cheap at 2,000 kWh and expensive at 500 kWh
The math behind the three average prices is straightforward even when the marketing isn't.
Every bill has two broad parts: usage-based charges (cents per kWh times consumption) and flat charges (monthly base fees from the REP plus the TDU customer charge). When you divide a bill with large flat fees by only 500 kWh, the average cost per kWh jumps. Spread the same flat fees across 2,000 kWh and the average falls—even if the underlying energy rate never changed.
That's why Power to Choose defines a base charge as a flat fee applied each month regardless of kWh used (⁷). Transmission and distribution—the actual delivery of electricity over poles and wires—is provided by your TDU and regulated by the PUC (⁷). TDU charges appear on every plan's EFL and factor into all three average-price tiers.
Bill credits push averages the other way. Some plans grant a credit only if you use at least 1,000 or 2,000 kWh in a cycle. At 500 kWh you miss the credit entirely; at 2,000 kWh you capture it—making the plan look like a bargain at high use and a bad deal at low use. The FAQ warns that minimum usage fees may apply below thresholds such as 500 or 1,000 kWh, sometimes under names like "minimum usage charge" (⁹).
Time-of-use plans add another wrinkle. EFL averages for those plans rely on REP estimates of how much energy you consume during discounted versus premium hours. If your habits do not match the estimate, your real average can diverge sharply from the label (⁷).
None of this is hypothetical fine print—it is why the PUC built a shopping tool that lets you filter plans with minimum usage fees and tiered rates before you compare (⁴).
What Killeen households pay in context
Comparing 500 and 2,000 kWh is about your bill, but statewide benchmarks help sanity-check results.
EIA's 2024 Texas electricity profile reports an average retail price of 9.79 cents per kWh across all customer classes—ranking 42nd lowest among states (¹⁰). That figure blends residential, commercial, and industrial sales; it is not the price on any single EFL.
Nationwide, EIA reports 2025 average retail prices of 17.30 cents per kWh for residential customers, with transmission, distribution, and regulatory structure driving wide state-to-state spreads (¹¹). EIA also notes that residential and commercial customers often pay higher per-kWh rates than industrial users because it costs more to serve smaller accounts (¹¹).
Residential electricity accounted for about 37.3% of U.S. retail sales in 2025, underscoring how much household usage drives the market you are shopping in (¹²).
For Killeen shoppers, the practical takeaway: the three published average prices on any EFL can diverge sharply from one another when base fees, credits, or usage penalties are in play. Always read the charge breakdown rather than trusting a single tier.
Calculate your real cost at 500 and 2,000 kWh
You do not need a spreadsheet to compare two plans at two usage levels—but you do need the EFL in front of you.
Step 1: Gather your usage history
Pull 12 months of bills from your current REP or past statements. Note your highest and lowest months. If summer peaks near 2,000 kWh and winter troughs near 500 kWh, compare plans at both levels instead of averaging mentally to 1,000.
Step 2: Write down each charge from the EFL
For each plan you are considering, list:
- REP energy charge (¢/kWh)
- REP base charge ($/month), if any
- TDU delivery charges (per kWh and fixed—shown on the EFL)
- Any bill credit thresholds and amounts
- Any minimum usage fee below a stated kWh level (⁹)
Step 3: Run the math twice
For each usage level (500 and 2,000 kWh):
Usage charges = (REP energy rate + TDU per-kWh delivery rate) × kWh used
Fixed charges = REP base charge + TDU fixed delivery charge
Subtotal = usage charges + fixed charges
Adjustments = add minimum usage fees or subtract bill credits if your kWh qualifies
Compare subtotals across plans at each usage level separately. A plan that wins at 500 kWh may lose at 2,000 kWh and vice versa.
Step 4: Sort results on Power to Choose the same way
Power to Choose lets you narrow plans by contract length, renewable content, price range, and whether the plan has minimum usage fees (⁴). After filtering, sort by the column closest to your typical month—but re-check the other columns before you enroll.
Red flags when comparing Killeen plans
Watch for these patterns when the 500 kWh and 2,000 kWh averages diverge by more than a few cents:
Large gap between 500 and 2,000 kWh averages. Usually signals heavy base charges, aggressive bill credits at high use, or minimum fees at low use. Confirm on the EFL.
Minimum usage fees. If you are an apartment user near 500 kWh, a plan that charges when usage drops below 1,000 kWh can erase a low advertised rate (⁹).
Variable or indexed rates without a price cap. Fine if you watch the market; risky if you want predictable summer bills (⁷).
Contract expiration. REPs must notify you before a term contract ends; if you do nothing, you may roll to a month-to-month variable rate (⁹).
Slamming and cramming. Switching without your consent or adding unauthorized fees is illegal. Report problems to the PUC at 1-888-PUC-TIPS (⁹).
You have a three-business-day right to cancel after receiving your Terms of Service, and ERCOT sends a confirmation mailer with cancellation instructions when you switch (¹).
Small businesses, renters, and shoppers from other states
Non-residential accounts follow the same TDU wires but often shop through negotiated or aggregated contracts rather than standard residential EFLs (¹³). If you run a shop, salon, or office in Killeen, confirm whether your meter class is residential or commercial before comparing 500/2,000 kWh residential benchmarks.
Renters who pay their own electric bill should match plan length to lease term when possible and avoid heavy early-termination fees if a move is likely. The FAQ notes that breaking an existing contract may carry penalties, so review your Terms of Service before switching (⁹).
If you are comparing Killeen's deregulated market to a regulated state—or to other states with retail choice—the core lesson still applies: the effective price depends on usage. In Texas, the EFL makes that visible through the 500/1,000/2,000 kWh tiers. Elsewhere, ask your supplier for a usage-based estimate rather than assuming a single advertised rate fits every home.
Not every Texas address has retail choice. Municipal utilities and cooperatives in some areas were not required to deregulate (⁹). Killeen residents in competitive areas can verify choice by entering a ZIP code on Power to Choose or calling 1-866-PWR-4-TEX (⁹).
Putting it together: a Killeen shopping checklist
- Enter your Killeen ZIP on ¹⁴ and confirm your TDU.
- Estimate monthly kWh from past bills; identify whether you are closer to 500, 1,000, or 2,000 kWh in a typical month—and in your worst summer month.
- Open the EFL for every finalist plan. Compare both 500 and 2,000 kWh average prices, then verify the underlying charges.
- Filter out plans with minimum usage fees if you routinely land near 500 kWh (⁴).
- Ask REPs the PUC's comparison questions, especially whether the rate includes all delivery and recurring fees (⁸).
- Enroll, keep your ERCOT confirmation, and know you can cancel within three business days if the Terms of Service are not what you expected (¹).
The cheapest Killeen electricity plan is not the one with the lowest number on the page—it is the one with the lowest total bill at the kWh levels you actually hit. Compare at 500 and 2,000 kWh, read the EFL line by line, and let the real math—not marketing—pick the winner.
