Minimum Usage Fees: The Small-Print Charge That Punishes Small Homes
A minimum usage fee is a flat charge some Texas electricity plans add when your monthly usage falls below a set threshold, most commonly 1,000 kWh. Example: a plan with a $9.95 minimum-usage fee turns a 500 kWh apartment's bill into a higher effective rate per kWh than the same plan charges a 1,500 kWh house, even though the advertised rate is identical.
Texas households average 1,095 kWh a month, per EIA 2026 data. That number matters more than it looks like it should, because a lot of Texas electricity plans quietly draw a line at 1,000 kWh. Use less than that in a given month, and some plans charge you an extra flat fee just for being small. Use more, and the fee disappears. It's called a minimum usage fee, and it's built to punish the exact households least equipped to absorb it: apartments, single-occupant homes, and anyone who actually succeeded at conserving energy.
How the Minimum Usage Fee Mechanic Works
A minimum usage fee is not a base charge, though the two get confused. A base charge is a flat monthly fee everyone on the plan pays, whether they use 200 kWh or 2,000 kWh. A minimum usage fee is conditional. It only shows up in months where your usage falls under a threshold the provider sets, almost always 1,000 kWh. Cross that line and the fee vanishes from your bill entirely. Stay under it and the fee gets added on top of whatever else you owe: your energy charge, your base charge, delivery charges, everything. It's a penalty for low usage, dressed up in small print.
The Worked Example: Same Plan, Different Effective Rate
Here's the math laid out plainly, using a labeled hypothetical plan (not a live quote, just a stand-in to show the mechanic). Say Plan A advertises a 9.5-cent-per-kWh energy charge, a $4.95 monthly base charge, and a $9.95 minimum usage fee that kicks in any month usage falls below 1,000 kWh. A studio apartment using 500 kWh pays: 500 kWh × 9.5¢ = $47.50 for energy, plus $4.95 base, plus the $9.95 minimum usage fee, for a total of $62.40. Divide that by 500 kWh and the effective rate (what you're really paying per kWh once every fee is folded in) comes out to 12.48¢/kWh. Now run the same plan for a 1,500 kWh house, close to what Katy households average: 1,500 kWh × 9.5¢ = $142.50, plus $4.95 base, no minimum usage fee because usage cleared 1,000 kWh. Total: $147.45. Effective rate: 9.83¢/kWh. Same rate card. Same provider. The small home pays about 27% more per kilowatt-hour than the big one.
Cities on the left average close enough to 1,000 kWh that a single mild month can push usage under the threshold. Cities on the right rarely get near it.
Who Gets Hit Hardest
The households most exposed to this fee aren't outliers. They're apartments and small homes in cities that already average close to the threshold. Pflugerville and Lubbock both average 1,080 kWh a month, Round Rock and Cedar Park average 1,100, and Austin averages 1,060, all Voltcheckr city estimates, EIA-anchored. (One note on Austin: most of the city proper is served by the municipal utility and doesn't shop retail plans at all, so this fee math applies to the Oncor-served suburbs around it.) Those are averages, meaning half the homes in each city use less. A mild March or October, when heating and air conditioning both sit idle, is enough to drop a normally-1,050-kWh household under 1,000 kWh for a month or two. That's precisely when a minimum usage fee plan bites, and it usually surprises people who thought they were being rewarded for using less power, not charged extra for it.
A 500 kWh apartment on the example plan above pays 12.48¢/kWh. A 1,500 kWh house on the exact same plan pays 9.83¢/kWh. Same provider, same rate card, same PDF. The apartment pays roughly 27% more for every kilowatt-hour it used, purely because it used less.
Ten-Second EFL Check
- Open the Electricity Facts Label (EFL), the standardized one-page disclosure every Texas plan must provide.
- Skip the big rate box at the top. That's the advertised rate, not necessarily your rate.
- Go straight to the 'Fees' or 'Other Charges' section further down the page.
- Search the page (Ctrl+F on desktop) for the word 'minimum.'
- If you find it, note the threshold (usually 1,000 kWh) and the dollar amount charged.
- Pull your last 12 months of billed kWh and check whether any month fell under that threshold before you sign.
Watch for what amounts to a bait-and-switch on the headline rate: a plan advertises an aggressively low cents-per-kWh number that's only true once you clear the minimum usage threshold. Below it, the fee erases the discount and then some. The lower the advertised rate, the more scrutiny the fee section deserves.
If your household regularly uses under 1,000 kWh, especially in spring and fall, filter for plans with no minimum usage fee at all before comparing rates. A slightly higher advertised cents-per-kWh with zero minimum usage fee often beats a lower advertised rate that penalizes you for conserving.
Texas households average 1,095 kWh a month, but averages hide a lot of apartments, singles, and efficient homes sitting well under that line every month. Voltcheckr's live comparison shows each plan's fee structure up front, so you can see whether a plan punishes low usage before you ever sign up.

It's a flat dollar charge added to your bill in any month your usage falls below a threshold the provider sets, usually 1,000 kWh. It's separate from the per-kWh energy rate and separate from the monthly base charge.
No. A base charge (see our base-charge glossary entry) is a flat fee every customer pays every month, regardless of usage. A minimum usage fee only applies conditionally, when your usage drops below the plan's threshold, and it stacks on top of any base charge that already exists.
1,000 kWh a month is the most common threshold on Texas retail plans. Texas households average 1,095 kWh a month, per EIA 2026 data, which is why the fee is more of a problem for apartments, single occupants, and efficient homes than for the average household.
Pull your last 12 months of billed kWh from a prior statement or your provider's usage history page. If any month dipped under 1,000 kWh, especially spring or fall, a plan with a minimum usage fee will likely charge you extra in those exact months.
Yes. Plenty of Texas plans carry no minimum usage fee at all. The only way to know is to read the EFL's fee section before you sign, or compare live plans side by side where the fee is disclosed up front.
