Average billing keeps your electricity bill the same every month — but the math only works in your favor if you understand what happens at settlement.
Texas summers punish the unprepared. A household that pays $90 in March can face $280 in August at the same rate, simply because the air conditioner runs six to eight hours a day instead of one. Budget billing, often called level pay or average billing, is the product the industry built to solve that volatility. It replaces twelve wildly unequal bills with one predictable payment.
What it does not do is eliminate the underlying cost. It defers, averages, and re-calculates. Knowing the difference between those three operations is what separates customers who come out neutral from customers who get hit with a $400 true-up charge in January.
This article explains how average billing programs work mechanically, how providers in the Texas retail market structure them differently, how to read the relevant section of an Electricity Facts Label before you enroll, and when the program is likely to work against you.
What Average Billing Actually Does
The core mechanism is simple. Your provider estimates your annual electricity spend, divides by twelve, and charges you that amount every month regardless of what you actually consumed in any given billing cycle.
Estimated annual spend divided by 12 equals your monthly level-pay amount.
For a household with an estimated annual bill of $1,800, the monthly charge is $150. In March, when actual usage might generate a $90 bill, the provider collects $150 and credits $60 to your running balance. In August, when actual usage generates a $280 bill, the provider collects $150 and draws $130 from your accumulated credit. If the credits run out before summer ends, you carry a debit balance.
That running balance — credit or debit — is the number most customers never check. It is also the number that determines how painful or painless your settlement will be.
The Settlement Event: Where Most Surprises Happen
Every average billing program has a settlement cycle, typically annual, sometimes semi-annual. At settlement, the provider compares the total you paid under the level-pay amount against the total you actually owed based on metered usage and your contracted rate.
If you paid more than you owed, you receive a credit or refund. If you owed more than you paid, the provider bills you the difference. That difference is the true-up charge.
True-up charges catch customers off guard for three reasons.
First, providers set the initial estimate using prior-year consumption data from your address or, for new accounts, a regional average. If you moved into an older, poorly insulated home, or if Texas had an unusually hot summer (2023 was the state’s second-hottest on record, per NOAA), the estimate undershoots reality.
Second, some providers re-calculate the level-pay amount mid-year if your running debit balance grows. PUCT rules let an electric company recalculate an average payment plan and adjust your required payment as often as every billing period (16 TAC §25.480(h)). The recalculation raises your monthly payment. Customers who were not expecting this describe it as an unexplained rate increase, and it generates complaints. LightCompanies’ PUCT complaint dataset covering July through December 2025 shows billing disputes as the leading complaint category across the 34 providers under active coverage.
Third, customers who cancel mid-cycle before settlement often face an immediate true-up rather than a pro-rated close; PUCT rules allow the company to collect any under-payment when service ends (16 TAC §25.480(h)). That timing matters if you are switching providers.
How to Read the EFL Before You Enroll
Every retail electricity provider operating in Texas is required to give you an Electricity Facts Label when you enroll and to post it for any plan sold on its website (16 TAC §25.475). The EFL is a standardized disclosure document covering price at benchmark usage levels, fees, contract term, and renewable content. For plans with average billing, the program mechanics live in a different document: 16 TAC §25.480(h) requires that all details concerning a level or average payment program be disclosed in the customer’s terms of service document, and that the plan reconcile any over- or under-payment at least every twelve months. Read the terms of service for the reconciliation cycle, the recalculation terms, and how the initial estimate is derived.
In practice, the level of disclosure varies. LightCompanies has reviewed 11 plan EFLs in detail with in-house math checks, and 10 of those plans were flagged for high-gimmick structure — meaning the stated rate does not reflect the actual all-in cost at typical usage tiers. Average billing plans are not automatically gimmicky, but their structure can obscure a rate that is already unfavorable before the averaging mechanism even enters the picture.
When reviewing an average billing plan, check four specific items across the EFL and the plan’s terms of service document.
The base rate at your usage tier. The EFL reports price per kilowatt-hour at 500 kWh, 1,000 kWh, and 2,000 kWh. Identify which tier reflects your actual household. A rate that looks competitive at 1,000 kWh may be significantly higher at 2,000 kWh if the plan includes a bill credit that phases out at higher usage. Average billing masks this because you never see the month-by-month bill variation.
The settlement cycle length. Annual settlement means a longer accumulation period, which means a larger potential true-up charge. Semi-annual settlement caps the exposure but also resets the averaging effect, which can produce a smaller but more frequent adjustment.
The recalculation trigger. Look for language describing what happens if your running balance exceeds a percentage of your estimated annual cost. If the contract does not specify a trigger, ask the provider in writing before enrolling.
The cancellation true-up clause. If you switch providers before your settlement date, this clause determines whether you owe the debit balance immediately. PUCT rules allow the company to collect any under-payment when your service ends (16 TAC §25.480(h)), so plan on the balance coming due.
When Average Billing Works in Your Favor
Average billing is a cash-flow tool, not a cost-reduction tool. Under a correctly structured program, you pay exactly what you would have paid anyway. The benefit is purely about predictability.
That predictability has genuine value in specific situations.
Households on fixed incomes benefit most. If your monthly inflows are stable and your budget has minimal slack, a $280 August bill can create a real shortfall even if the annual total is manageable. Level-pay converts that spike into a flat obligation.
Renters who are responsible for electricity but not for weatherization improvements face the same problem. You cannot install better insulation or replace the aging HVAC unit. You can, however, average out the penalty of living in an inefficient building.
Households with highly predictable usage — small square footage, mild local climate, minimal cooling load — may find that the initial estimate tracks actual usage closely enough that the settlement event produces a minimal adjustment. The program performs as advertised when the estimate is accurate.
When Average Billing Works Against You
The program works against you in several identifiable scenarios.
If your usage is trending upward relative to the prior year, the estimate will undershoot reality from the start. Usage trends upward when you add a second unit to the household, replace gas appliances with electric, begin working from home full-time, or experience a significantly hotter summer than the baseline year. Each of these scenarios produces a growing debit balance and a larger-than-expected true-up.
If the underlying rate is not competitive, average billing obscures the problem. Paying an uncompetitive rate in predictable installments still means paying an uncompetitive rate. Compare the base rate at your usage tier against other available plans in your zip code before enrolling. Comparing against Reliant and TXU at the same usage tier is a reasonable starting point for a ballpark check, but the specific rate varies by plan and promotional period, so direct EFL comparisons are the only reliable method.
If you are likely to move or switch providers within 12 months, the cancellation true-up clause can turn a small debit balance into an immediate lump-sum charge. Customers who switch to chase a better rate mid-cycle sometimes find that the switching benefit is partially or fully offset by the true-up they did not anticipate.
How Providers Structure These Programs Differently
Not all average billing programs are identical, and the structural differences matter.
Some providers run level-pay as a standalone feature on any qualifying fixed-rate plan. Others bundle it with specific plan tiers, sometimes attaching it to plans with higher base rates on the premise that the predictability feature justifies the premium. If you are enrolling in a bundled product, you need to isolate the rate from the feature and evaluate each separately.
Some providers offer a running balance display in the customer portal, updated monthly. This is operationally useful because it lets you see whether you are tracking toward a credit or a debit before settlement arrives. Others provide no real-time balance visibility, which means the first time you know there is a problem is when the recalculation notice arrives.
One structural point worth noting: in Texas’s competitive areas, the wires utility does not bill you directly. Its delivery charges arrive on your electric company’s bill (16 TAC §25.479), so a level-pay amount covers energy and delivery together and there is no separate utility-level averaging to reconcile. The full settlement exposure sits in one place, your electric company’s terms of service.
Practical Steps Before You Enroll
Four steps reduce the risk of an unwelcome settlement charge.
Pull 12 months of usage history from Smart Meter Texas (smartmetertexas.com), the usage portal the wires utilities direct customers to, before you enroll. That data stays with the meter regardless of which electric company you use. Calculate your own annual estimated cost using the actual rate from the EFL at your average monthly usage tier. Compare that number to the provider’s stated level-pay amount. If the numbers diverge by more than 5 percent, ask the provider how they derived the estimate.
Set a calendar reminder three months before your settlement date to request your current running balance. A debit balance three months out gives you time to increase your payments voluntarily (if the provider allows it) or to budget for the true-up.
Read the cancellation clause before you switch. If you are leaving a level-pay plan, time the switch to coincide with or follow your settlement date where possible.
Finally, check whether the underlying plan rate is competitive independent of the averaging feature. Average billing on a well-priced plan is a neutral-to-positive feature. Average billing on an overpriced plan is a way to pay a premium without noticing it month to month.
The Bottom Line on Average Billing
Average billing solves a specific, real problem: month-to-month bill volatility in a climate where summer cooling costs can triple a winter bill. For households where cash-flow predictability matters more than optimizing the annual total, the program delivers on its stated purpose.
It does not lower costs. It does not protect against rate increases on variable-rate plans (PUCT rules require every electric company to make a level or average payment plan available to customers who are not behind on their bills and to disclose the plan’s details in the terms of service document, 16 TAC §25.480(h); read those terms to see how the plan handles a variable rate). It does not eliminate the obligation to pay what you actually used.
The customers who benefit from it are those who read the settlement terms before enrolling, monitor their running balance during the year, and choose an underlying plan with a competitive rate independent of the averaging feature. The customers who are surprised by it are those who treat the level-pay amount as the total cost and stop reading there.
