Low-Usage Texas Electric Plans: Compare Real Cost Under 500 kWh
If your monthly electricity use often lands at or below 500 kilowatt-hours (kWh), the plan that looks cheapest on a billboard is rarely the plan that costs you the least. In competitive areas of Texas, retail electric providers (REPs) advertise prices tied to standardized usage levels—500, 1,000, and 2,000 kWh per month—but your real bill depends on fixed charges, delivery fees, bill credits, and penalties for light use that do not show up in a simple ¢/kWh quote.
This guide explains how to compare all-in cost at 500 kWh, who should shop that way, and how the same logic applies in other choice states.
Why 500 kWh Is the Benchmark Low-Usage Shoppers Need
Texas regulators require every residential Electricity Facts Label (EFL) to show the total average price per kWh at 500, 1,000, and 2,000 kWh per month, rounded to the nearest tenth of a cent (¹). Those three anchors exist so households with different consumption patterns can compare offers on the same footing—not because anyone expects every home to use exactly 500 kWh every month.
For many shoppers, 500 kWh is the right column to study first:
- Seasonal lows. The ² notes that usage follows seasonal patterns, with higher consumption in months like August and February. A household that averages 900 kWh annually may still hit 500 kWh (or less) in mild spring or fall months.
- Smaller footprints. Renters, single-person homes, well-insulated apartments, and second properties often cluster below the statewide norm. The ³ cites a national average near 1,000 kWh per month for residential consumption—useful context, but Texas homes with electric heating and long cooling seasons often run higher in peak months and lower in shoulder months.
- Fee tripwires. Reporting on the Texas market found that many retailers charge roughly $7–$20 per month in minimum-use fees when monthly use falls below 1,000 kWh (⁴; ⁵). At 500 kWh, you are squarely in the zone where those structures matter.
The point is not to memorize 500 kWh as your forever usage. It is to stress-test plans against a credible low month before you sign.
Texas Choice in Plain English
If you live in the Electric Reliability Council of Texas (ERCOT) region and are not served by an electric cooperative or municipally owned utility, you generally have the power to choose your retail electric provider (⁶). The Public Utility Commission of Texas (PUCT) directs consumers to ⁷ as the official, unbiased comparison site where providers list offers for free.
Power to Choose is not the only way to shop, but it is the reference point the PUCT uses when it tells Texans to compare current pricing—especially since the commission stopped updating its quarterly and annual residential bill-comparison tables in January 2025 and now points shoppers to Power to Choose for live offers (⁸).
Outside ERCOT, or in cooperative and municipal territories, you may have a single bundled provider. Ohio and Maryland also allow retail choice in many areas; the same EFL-style discipline—match the plan to your actual kWh band—applies even where the shopping portal differs.
The Electricity Facts Label: Your Real Comparison Tool
Think of the EFL as a nutrition label for power. The PUCT describes it as a standardized format (⁹) for apples-to-apples comparison of prices and contract terms. The ¹⁰ publishes state average bills in Table T5.a. Under ¹, each EFL must disclose:
- Whether the product is fixed or variable
- The total average price per kWh at 500, 1,000, and 2,000 kWh for residential customers
- That the average price reflects all recurring charges (excluding sales tax and certain pass-through items spelled out in the rule)
- A listing of other fees the REP may charge, and whether each fee is included in the recurring-charge calculation
How to translate the 500 kWh row into dollars
The EFL’s 500 kWh column is an all-in average rate, not merely the energy supply rate. To estimate your supply-side bill before taxes:
Estimated monthly energy charge ≈ (EFL average ¢/kWh at 500 kWh) × (your actual kWh) ÷ 100
Example: if the EFL shows 14.0¢/kWh at 500 kWh, a 500 kWh month models to about $70.00 in bundled recurring charges on the supply portion—plus any fees not included in that average, and plus TDU delivery charges if they are passed through separately on your bill format.
Always read the fee section below the average-price table. PUCT rules require REPs to list assessable fees (¹) and flag whether each is baked into the recurring average.
What the EFL does not replace
¹¹ warned that the Facts Label is indispensable but does not substitute for reading the Terms of Service. Variable-rate plans, cancellation penalties, and billing practices may only be clear in that second document. The ¹² has similarly cautioned that competitive electricity markets produce wide varieties of price offers and contract terms that can be difficult to evaluate from advertising alone.
Bill Building Blocks That Hit Low Users Hardest
A Texas residential bill in a competitive area typically combines:
- REP supply charges — energy, recurring monthly charges, and sometimes usage-based credits or penalties
- TDU (wires) delivery charges — regulated transmission and distribution costs set by your local utility and approved by the PUCT. The PUCT publishes ¹³; everyone in the same TDU territory pays the same delivery rates regardless of which REP you pick.
The PUCT publishes TDU rate information separately from retail offers. Delivery costs are real and non-negotiable, but they are also not a reason to ignore the 500 kWh column on the supply EFL—low users still feel fixed and threshold fees disproportionately.
Fixed monthly charges vs. minimum-use fees
¹¹ explained a distinction that still applies today:
- Monthly service / base charges are recurring fees many REPs include in the EFL average. They spread across your kWh. For a minimal user, a high base charge hurts more because there are fewer kWh to divide it over.
- Minimum-use fees (sometimes framed as charges for falling below a threshold) are different. ⁴ described fees triggered when use falls under 1,000 kWh, with dollar amounts that vary by company and are not standardized across the market.
A low-use month can stack TDU customer charges, a REP base charge, and a minimum-use fee in the same bill.
Bill credits and tiered pricing
Some plans advertise low ¢/kWh rates but include bill credits only when you cross a usage threshold (for example, $50 off at 1,000 kWh). At 500 kWh, you may receive no credit, so your effective rate jumps. Tiered products may charge one rate for the first block of kWh and another rate above it. The 500 kWh EFL column captures the net effect of many—but not all—of these games. That is why it is the first number to read.
The ² lets you filter out plans with minimum usage fees/credits and tiered rates—a useful starting point if you know you are a low or variable user.
Who Should Optimize for 500 kWh?
Shop to the 500 kWh column if any of the following sound like you:
- Apartment or condo with smaller square footage
- Single occupant or rarely home
- Highly efficient home with LED lighting and efficient appliances
- Seasonal or vacation property with months well under 1,000 kWh
- Small home-based business on a residential meter with light equipment loads
If your usage is usually above 1,000 kWh but occasionally dips near 500 kWh, compare both the 500 kWh and 1,000 kWh columns. A plan that wins at 1,000 kWh can still be expensive in a mild month.
Step-by-Step: Compare Real Cost at 500 kWh
1. Establish your usage band
Pull 12 months of bills or your REP portal history. Note the low month, the high month, and the average. Power to Choose’s guide recommends calculating your estimated average while remembering seasonal swings.
2. Start on Power to Choose (or an equivalent EFL source)
Enter your ZIP code on ⁷. Narrow results:
- Set contract length preferences
- Consider filtering out minimum-fee/tiered products if you want simpler math
- Select your TDU if prompted (Houston-area CenterPoint, North Texas Oncor, etc.)

3. Sort by the 500 kWh all-in average—not headline energy rate
For each finalist, open the EFL (Fact Sheet). Record:
| Field | Plan A | Plan B |
|---|---|---|
| Avg ¢/kWh @ 500 kWh | ||
| Avg ¢/kWh @ 1,000 kWh | ||
| Contract length | ||
| Early termination fee | ||
| Notable fees (base, min-use, autopay) |
4. Model your low month
Use the formula:
Modeled bill ≈ (¢/kWh at 500 kWh) × (expected low-month kWh) ÷ 100
Repeat for a typical month at 1,000 kWh if you want a blended view.
5. Read Terms of Service for surprises
Look for variable-rate adjustment language, autopay discounts, deposit policies, and disconnect/reconnect fees. Consumer advocates have long criticized non-standard fee presentations in Texas retail markets; assume nothing is “standard” unless it is on your EFL/TOS.
6. Check renewal rules before you switch
If you are mid-contract, compare projected savings against any early termination fee. A cheaper 500 kWh average still loses if cancellation costs eat the first year of savings.
Plan Types That Often Punish or Reward Low Use
| Plan feature | Risk at ~500 kWh | What to check on EFL |
|---|---|---|
| High base charge | Raises effective ¢/kWh | 500 vs 1,000 kWh gap |
| Minimum-use fee below 1,000 kWh | Flat penalty in light months | Fee section; 500 kWh rate spike |
| Usage bill credit at 1,000+ kWh | No credit when usage is low | 500 kWh vs 1,000 kWh columns |
| Tiered block rates | Low block may be pricey | Tier definitions in TOS |
| Variable rate | Budget volatility | Historical price URL on EFL |
| Time-of-use | Off-peak savings only if pattern fits | On-/off-peak averages if listed |
Prepaid plans can avoid some minimum-use structures but introduce other fees and disconnect rules—read that product’s EFL separately.
A Side-by-Side Illustration (Structure, Not a Quote)
Suppose two 12-month fixed plans in the same TDU territory show these EFL averages:
- Plan A: 13.5¢ at 500 kWh; 11.8¢ at 1,000 kWh
- Plan B: 11.9¢ at 500 kWh; 12.6¢ at 1,000 kWh
At exactly 500 kWh, Plan B models to $59.50; Plan A to $67.50—about $8.00 lower— even though Plan A looks cheaper at 1,000 kWh.
That inversion is common when Plan A relies on bill credits or low per-kWh energy rates that only materialize at higher use. Your job is to compare at the kWh you actually expect, not the kWh on the ad.
Regulated Markets and Other Choice States
If you are not in a competitive Texas territory:
- You may not choose your generation supplier. Focus on efficiency, time-of-use options if offered, and assistance programs through your utility.
- In states with retail choice—¹⁴ notes 13 states and the District of Columbia for electric supplier choice, with Texas the largest open market—comparison sites and disclosure formats differ. The discipline stays the same: translate offers to your usage band, read contract fine print, and be skeptical of variable rates and hidden fees.
Maryland and Ohio shoppers should use state-approved comparison resources and still demand an EFL or state-equivalent disclosure before enrolling.
Red Flags Before You Enroll
- Large spread between 500 kWh and 1,000 kWh averages without an obvious explanation—often signals credits, tiers, or minimum-use rules
- Teaser rate tied to autopay, bundled products, or new-customer bonuses averaged into the EFL
- Variable price without a clear ceiling or historical-price link
- Multiyear lock when your usage pattern is uncertain
- Marketing below 1,000 kWh that does not show a 500 kWh EFL column (non-compliant for Texas residential EFLs)
¹⁵ advises watching promotional prices that rise after intro periods. The ¹² emphasizes uniform disclosures because advertising alone often omits material price components.
Practical Checklist for Low-Usage Texas Shoppers
- Confirm you are in an ERCOT competitive area via Power to Choose ZIP lookup.
- Gather 12 months of kWh history; identify low and high months.
- Filter for plans without minimum-use/tier complexity if you want simplicity.
- Rank finalists by EFL 500 kWh average ¢/kWh.
- Model dollars for your expected low month and your average month.
- Read Terms of Service for variable rules, fees, and exit costs.
- Set a calendar reminder 30–45 days before contract end to re-shop.
The Bottom Line
For low-usage Texas households, the real cost under 500 kWh is whatever the EFL’s 500 kWh all-in average says, adjusted for any excluded fees and your actual metered use—not the advertised energy rate at 1,000 or 2,000 kWh. ⁷ and the ¹ give you the tools to see that number before you commit. Use them every time you shop, switch, or renew—especially if your monthly use lives on the low side of the meter.
