Why Texas Power Rates Jump at 500, 1,000, and 2,000 kWh

Open almost any Texas electricity offer and you will see three prices: one at 500 kilowatt-hours (kWh), one at 1,000 kWh, and one at 2,000 kWh. The middle number often looks like a steal. The low-usage number can look punishing. The high-usage number may drift up or down in ways that do not match a simple "volume discount." Those swings are not a glitch in the shopping site. They are how Texas retail plans are required to disclose price—and how many plans are structured to look cheapest at the usage level shoppers sort by.

This article explains what those three numbers mean, why they jump, and how to use them when you are shopping, switching, renewing, or starting service. The focus is deregulated Texas, with notes for other choice markets and regulated utilities.

Those Three Numbers Are Required Disclosure Points

In competitive areas of Texas, retail electric providers (REPs) sell the electricity; local wires companies deliver it. The Public Utility Commission of Texas (PUC) requires every plan to publish an Electricity Facts Label (EFL)—a standardized sheet, often compared to a nutrition label, covering prices, fees, and contract terms so shoppers can compare offers side by side (¹; ²).

PUC customer-protection rules go further: for residential products, the EFL must state the total average price for electric service—in cents per kWh, rounded to the nearest tenth of a cent—at exactly 500, 1,000, and 2,000 kWh per month. That average price must reflect recurring charges (excluding certain taxes) (³). Small commercial EFLs use different anchors (1,500 / 2,500 / 3,500 kWh), but the idea is the same: fixed checkpoints, not a prediction of your personal bill.

Those checkpoints also sit near how much households actually use. U.S. Energy Information Administration (EIA) data for 2024 put Texas residential average monthly consumption at 1,096 kWh, with an average price of 14.94 cents/kWh and an average bill of $163.72—well above the U.S. average usage of 863 kWh (⁴; ⁵). Former PUC chair Donna Nelson told the Texas Tribune the average Texan uses about 1,000 to 1,200 kWh a month, and that Power to Choose eventually required up-front postings at 500, 1,000, and 2,000 kWh after earlier confusion when only the 1,000 kWh figure was easy to see (⁶).

So the three columns are regulatory landmarks around typical Texas load—not marketing poetry. Retailers still design products knowing shoppers stare hardest at the middle column.

What "Average Price" Means on an EFL

The EFL "average price" is not just the energy charge printed in an ad. It is an all-in cents-per-kWh figure at that usage level, bundling the recurring pieces of the product so you can compare plans without reverse-engineering every fee (³; ⁷).

That math mixes:

• Energy charges (what the REP charges for the power itself)
• Base charges (flat monthly fees regardless of usage—defined on Power to Choose as a flat fee applied each month regardless of kWh used) (²)
• Delivery / TDU charges passed through for poles, wires, and metering
• Credits or minimum-usage fees that apply only in certain usage bands

Divide the estimated monthly bill by the usage (500, 1,000, or 2,000), and you get the three cents-per-kWh figures on the label. Flat fees loom large when you divide by 500. A bill credit that only unlocks near 1,000 kWh can crush the middle number. At 2,000 kWh, the same credit is spread over twice as many kilowatt-hours—or may no longer apply—so the average can rise even if nothing "went wrong."

Power to Choose and comparison tools surface those three EFL prices because that is what providers must calculate. WattKarma, for example, shows plan rates at 500, 1,000, and 2,000 kWh and notes that the same plan can look more expensive at 500 than at 1,000 (⁸). The trap is treating the middle number as "your rate" when your meter rarely lands on exactly 1,000 kWh.

Bill Credits and the 1,000 kWh Cliff

Many competitive plans include a bill credit or usage credit: a dollar amount off the bill when monthly usage falls inside a defined range. Power to Choose's FAQ notes that some companies offer credits or waivers of other fees for using a certain amount of electricity, and its glossary entry on minimum monthly fees also flags associated fees or credits (⁹; ²). WattKarma describes usage-credit plans as awarding an automatic monthly credit—often $50, $75, or $100+, sometimes cited in the $50–$150 range—when usage stays in the plan's target band, and no credit when usage falls outside it (¹⁰).

Here is why the EFL columns jump. Suppose (illustratively) a plan's energy charge is 12¢/kWh, recurring fixed charges add $20 before tax, and a $50 credit applies only at or above 1,000 kWh:

• At 1,000 kWh, energy is $120 + $20 − $50 = $90 → 9.0¢/kWh average before tax nuances
• At 500 kWh, energy is $60 + $20 with no credit = $80 → 16.0¢/kWh
• At 2,000 kWh, if the credit still applies once, energy is $240 + $20 − $50 = $210 → 10.5¢/kWh

The plan did not secretly raise your rate between 500 and 1,000. The credit simply did not exist at 500, so the average price "jumps." Advertised rates often spotlight the usage level where the credit is fully baked in—commonly around 1,000 or 2,000 kWh (⁷).

Regulators have long worried about that optics game. In 2016, PUC leaders called out listings that looked artificially cheap—down to about 1¢/kWh—and said some providers were "working the system" with tricky price structures on the Power to Choose "nutrition label" (¹¹; ⁶). The shopping tool was updated to filter out prices with built-in credits for certain usage amounts, weeding out offers that appeared unrealistically cheap (⁶). Credit structures still exist in the market; the lesson for shoppers is to read the EFL band language, not just the sorted headline.

Credit plans can be a genuine fit if your usage is steady and typically lands inside the band. They are a poor fit for seasonal vacations, mild springs that drop apartment usage, or households that bounce between 600 and 1,400 kWh. WattKarma notes they work best for predictable monthly use and worse for highly variable or seasonal patterns (¹⁰; ¹²).

Minimum Usage Fees: Paying More for Using Less

The mirror image of a usage credit is a minimum usage fee (also called a minimum usage charge or minimum monthly fee). If you use less than a set kWh amount in a billing period, the plan adds a fee. Power to Choose says typical cut-off points that might incur a fee are less than 500 or 1,000 kWh, that the fee may or may not appear as a separate line on the bill, and that you should check the EFL (⁹; ²).

That fee inflates the 500 kWh average price on the EFL because the extra dollars are divided by a small usage number. At 1,000 kWh, the fee often disappears, so the middle column suddenly looks better—even if the energy rate never changed.

Reporting has documented how common these terms can be. A Texas Tribune feature on legislation aimed at banning "fees for conserving electricity" described customers charged roughly $10 surcharges for using under 1,000 kWh, cited a consumer-group survey finding minimum fees of about $7 to $20 among many Oncor-area fixed plans, and noted a Houston Chronicle finding that more than 70% of Houston-area options then included terms that penalized using too little power (¹³). Industry groups argued the fees help cover fixed account costs and that unhappy customers can switch; consumer advocates argued the fees punish conservation and hit fixed-income households hardest (¹³).

If you live in a small apartment, travel often, or keep winter and shoulder-season usage well under 1,000 kWh, a plan with a minimum-usage fee can erase the savings you thought you bought. Power to Choose's shopping tool lets you see whether a company requires minimum electricity usage and whether an associated fee or credit applies—then still open the EFL for the full arithmetic (²).

Why 500 kWh Often Looks Expensive—Even Without a "Gotcha"

Even on a straightforward fixed-rate plan with no credit and no minimum fee, the 500 kWh column is often higher than the 1,000 and 2,000 columns. Two structural reasons dominate.

First, base charges. A flat monthly fee of even a few dollars becomes a large cents-per-kWh adder when usage is low. Ten dollars of fixed retail fees is 2.0¢/kWh at 500 kWh, 1.0¢ at 1,000, and 0.5¢ at 2,000. WattKarma warns that some plans advertise a low energy rate while adding monthly base charges of $5 to $15 or more (⁷).

Second, delivery charges include fixed pieces (customer and metering charges) plus per-kWh pieces. Oncor explains that REPs bill customers for energy and for delivery; TDU/delivery charges reflect poles, wires, and meters, with rates regulated by the PUC, and residential delivery includes fixed monthly items plus variable per-kWh factors (¹⁴). Power to Choose likewise separates the REP (seller) from the local wires company that delivers power, reads meters, and maintains poles regardless of which REP you choose (⁹).

So a "jump" from the 500 column to the 1,000 column can simply mean fixed costs are being amortized over more kilowatt-hours. That is normal. The red flag is when the gap is huge—signaling credits, minimum fees, or steep tiers—not when the low-usage column is a bit higher.

What Changes at 2,000 kWh

The 2,000 kWh column answers a different question: what happens when usage is high—large homes, hot summers, electric heating, pools, or EV charging.

Several patterns show up:

• Credit dilution. A flat $75 credit that made 1,000 kWh look cheap is only 3.75¢/kWh at 2,000 kWh. The average price can rise even though you still received the credit.
• Credit caps. Some credits apply only inside a band (for example, 1,000–1,999 kWh). Above the band, the EFL average can jump because the credit vanishes.
• Tiered energy charges. Some plans charge one rate for early kWh and another rate after a breakpoint. WattKarma notes that tiered pricing and usage credits can help or hurt depending on whether they match your consumption (⁷).
• Seasonal reality. WattKarma notes many Texas homes use roughly 1,000 to 2,000 kWh monthly depending on size and habits, and that summer use in warm climates can be two or three times winter use (¹²). If July sits near 2,000 kWh and April sits near 700, one plan rarely wins both months on the same EFL column.

High users should weight the 2,000 kWh figure—and still check whether a credit disappears above a threshold. Low users should weight 500 kWh and avoid minimum-fee plans. Average users near the EIA statewide mean (~1,100 kWh) still need to know whether a 1,000 kWh teaser depends on a cliff they sometimes miss.

Delivery Charges Are the Same Wires Company—But They Still Move the Average

Shoppers sometimes assume different REPs mean different wires charges. In deregulated Texas, four major TDSPs/TDUs operate in competitive zones—Oncor, CenterPoint Energy Houston Electric, Texas-New Mexico Power, and AEP Texas—and the TDSP bills the REP for delivery and metering, which the REP passes through on your bill (¹⁴). Reliability and outage response stay with the wires company; choosing a REP changes who sells you energy and how the plan is priced, not who owns the poles (⁹).

Delivery still matters for the three EFL columns because delivery has fixed and volumetric pieces. Historical reporting also showed delivery making up a large slice of bills: a Texas Coalition for Affordable Power analysis cited by the Texas Tribune found CenterPoint delivery charges on a 1,000 kWh bill rising from $24.61 in 2003 to $42.41 by March 2016, and Oncor from $23.01 to $36.87 over the same span (¹⁵). Those figures are dated, but the structural point remains: wires costs are real, regulated, and embedded in the average prices you compare.

The same Tribune piece noted competitive areas covering about 85% of Texas and that regulated municipal and cooperative territories still do not offer retail choice in the same way (¹⁵; ⁹).

How to Shop Your Real Usage (Not the Middle Column)

1. Find your kWh pattern. Pull 12 months of bills if you can. Note the summer peak, winter peak, and shoulder months. Power to Choose's guidance for comparing offers starts from knowing your usage and asking questions keyed to a 1,000 kWh benchmark—while still recognizing that your real load may differ (¹⁶).

2. Open every EFL. Confirm average prices at 500 / 1,000 / 2,000, then read the fine print for bill credits, minimum usage fees, base charges, early termination fees, and whether the product is fixed, variable, or indexed (²; ¹²). WattKarma notes early termination fees on fixed contracts commonly land around $100 to $200 (⁷).

3. Rank plans at your usage, not the sort default. If you average 750 kWh, a plan that wins at 1,000 kWh because of a credit may lose badly at 750. If you average 1,800 kWh, ignore apartment-oriented low-use specials.

4. Stress-test the cliffs. Ask: what happens at 999 kWh? At 1,001? Above 2,000? If missing the credit by a few kilowatt-hours nearly doubles your effective rate, you need either a steadier usage pattern or a flatter plan.

5. Remember contract and product type. Fixed-rate plans keep the disclosed energy price stable for the term except for allowed pass-throughs such as TDU fee changes and certain administrative or government-imposed charges (²; ³). Variable plans can move month to month. Time-of-use averages on the EFL depend on assumed on-peak vs off-peak shares; if you do not shift load, your bill can rise (²).

6. Use official and independent comparison carefully. ⁹ is the PUC's shopping portal. Licensed comparison services can also sort by ZIP and explain terms; WattKarma, for example, aggregates plans across deregulated Texas territories including Oncor, CenterPoint, AEP Texas, and TNMP (⁸). Either way, the EFL—not the ad—is the document that matters.

Outside Competitive Texas: Choice States and Regulated Bills

Not every ZIP code in Texas has retail choice. Municipal utilities and cooperatives were not required to deregulate; Power to Choose directs residents to check by ZIP or call to see whether choice is available (⁹; ¹³). In those areas you typically face a regulated tariff, not a Power to Choose menu—but bills can still have customer charges, tiered energy blocks, and seasonal rates that make the cents-per-kWh effective rate change with usage.

In other U.S. choice markets (parts of Ohio, Maryland, and elsewhere), suppliers may advertise a teaser energy rate while the utility still bills distribution. The Texas-specific 500 / 1,000 / 2,000 EFL grid is not universal, but the shopping discipline is: compare all-in cost at your kWh, watch for introductory periods, and read the contract for early-exit fees. EIA's state average bills remain a useful reality check for whether a quote is in the ballpark of local residential norms (⁴).

Small businesses in Texas competitive areas should note the EFL uses different checkpoints (1,500 / 2,500 / 3,500 kWh) under the same PUC rule (³). The cliff logic—credits, minimums, and fixed fees—still applies; only the yardsticks change.

A Practical Decision Checklist

• Know your range: low months, average months, and peak months in kWh—not a single guess.
• Read all three EFL prices: a giant gap between 500 and 1,000 usually means credits or minimum fees; a rising 2,000 column can mean credit dilution or tiers.
• Match the mechanism to your life: steady mid-usage can make a usage credit work; variable or low usage usually favors simpler pricing without cliffs (¹⁰).
• Do not confuse wires with retailer: delivery stays with the TDSP; shop the REP plan on top of it (¹⁴).
• Confirm fixed vs variable and exit costs before you enroll (¹⁶).
• Re-shop before renewal: contract-expiration notices exist for a reason; rolling to a month-to-month variable product after a fixed term can change the price story overnight (⁹).

Texas did not invent three magic usage levels to confuse you. Regulators standardized 500, 1,000, and 2,000 kWh so households with different load shapes could compare the same plan on the same sheet (³; ⁶). Retailers then built products—and ads—around those landmarks. When the columns jump, read them as a map of fees and credits across usage, not as three unrelated "rates." Shop the column closest to how you actually live, stress-test the cliffs, and let the EFL—not the billboard—decide.
