Minimum Usage Fee Texas Electricity: What to Know

A Dallas apartment renter signs up for a plan advertised at 9 cents per kilowatt-hour, runs the air conditioning lightly during a mild October, uses 480 kWh, and opens a bill that looks nothing like the math she expected. Buried in the charges is a $9.95 credit subtracted in reverse: a minimum usage fee because she didn't hit 500 kWh.

This is not a billing error. It is a legal, disclosed plan feature that tens of thousands of Texas customers encounter every year, usually without realizing they agreed to it. The fee is real, it is common, and it is entirely avoidable once you know what to look for.

A minimum usage fee (sometimes called a minimum usage charge or a below-threshold credit reversal) is a fixed dollar amount that a Retail Electric Provider adds to your bill when your consumption for the billing period falls below a stated kilowatt-hour level. The most common thresholds in Texas are 500 kWh and 1,000 kWh, though some plans use 750 kWh or other figures.

The fee is not the same as a base charge or a customer charge, both of which appear on almost every plan regardless of usage. A base charge is flat and universal. A minimum usage fee is conditional: it only triggers when you use less than the threshold. Some REPs frame it as a bill credit that disappears below the threshold, which produces the same financial result but reads differently on the plan documents.

The practical effect is that your all-in cost per kWh rises sharply in any month your usage dips. A plan with a $9.95 minimum usage fee and a 500 kWh threshold adds nearly 2 cents per kWh to your effective rate at exactly 500 kWh, and the impact compounds as usage drops further.

Retail Electric Providers in Texas operate in a fully competitive market regulated by the Public Utility Commission of Texas (PUCT). They buy electricity in wholesale markets, layer on margins, and compete heavily on the advertised per-kWh rate. That competition pushes headline rates down, but REPs still need to recover fixed costs: customer account overhead, billing systems, and the pass-through delivery fees that TDUs like Oncor, CenterPoint, AEP Texas, and TNMP charge on every account regardless of how much power flows.

Minimum usage fees let a REP offer a low headline rate while ensuring that customers who consume very little still cover a floor of fixed costs. The structure is not inherently predatory, but it does mean that the advertised rate is most accurate at the usage tier it was designed for, typically 1,000 kWh per month, which is the middle benchmark on Texas Electricity Facts Labels.

Every plan sold by a licensed REP in Texas must come with an Electricity Facts Label (EFL), a standardized disclosure document required by the PUCT. The EFL is the authoritative source for what you will actually pay. Reading it before you enroll is not optional if you want to avoid surprises.

Here is where to look:

1. The average price table at the top. The EFL shows average prices at 500 kWh, 1,000 kWh, and 2,000 kWh. If the price at 500 kWh is dramatically higher than at 1,000 kWh, a minimum usage fee or a disappearing bill credit is almost certainly the reason.

2. The price breakdown section. Scroll past the summary table to the itemized charges. Look for language like "minimum usage charge," "below-threshold fee," "usage credit," or "bill credit (usage requirement)." The dollar amount and the kWh threshold will be stated explicitly.

3. The contract terms and conditions. Some REPs bury the mechanics in the Terms of Service rather than the EFL itself. Read both.

If the EFL is unclear, you have the right to ask the REP for clarification before signing. You can also compare EFLs side by side at powertochoose.org, the official PUCT shopping site, or at ElectricRates.org's Texas rate comparison tool.

Not every Texas household is equally exposed. Usage patterns that frequently dip below common thresholds include:

Small apartments and studios. A one-bedroom unit with modest appliances, no electric water heater, and no dryer can easily land under 500 kWh in mild months.

Snowbirds and part-time residents. A house that sits mostly empty for several months a year will have very low usage during those stretches, even with the refrigerator running.

Households with rooftop solar. Net consumption after solar generation can fall below thresholds regularly, meaning the minimum usage fee structure may offset some of the savings solar was meant to provide.

Mild-weather months for average homes. Even a typical 1,500-square-foot home can dip below 500 kWh in October or April when neither heavy heating nor heavy cooling is needed.

If your usage is consistently low or seasonal, a plan without a minimum usage fee (or with a very low one) is worth seeking out specifically, even if the headline per-kWh rate is slightly higher.

As of July 2026, the lowest all-in advertised rate available in the Oncor service territory (Dallas area) at 1,000 kWh is roughly 7.2 cents per kWh, across approximately 131 active plans. The median all-in rate at that same usage level is about 16.5 cents per kWh. Those figures come from plan EFLs aggregated across active offers.

The gap between 7.2 and 16.5 cents is wide, and minimum usage fees contribute to that spread when you compare plans at different consumption levels. A plan that looks like 7.2 cents at 1,000 kWh might show 11 or 13 cents at 500 kWh once a minimum usage fee is factored in. A plan sitting at 12 cents at 1,000 kWh with no minimum usage fee may actually be cheaper for a household that uses 400 to 600 kWh most months.

Rates vary by TDU territory and by usage tier. The numbers above apply to the Oncor area. Customers in CenterPoint (Houston), AEP Texas, or TNMP territories will see different figures. Check ElectricRates.org for live, territory-specific comparisons.

Shopping on headline rate alone is how customers end up with minimum usage fee surprises. A more reliable approach:

Start with your actual usage. Pull the last 12 months of usage from your TDU's SmartMeter Texas portal (smartmetertexas.com). Find your lowest-usage month. That is your worst-case scenario for a minimum usage fee.

Compare at your real usage tier. On powertochoose.org, you can filter plans by usage level. Look at the 500 kWh column if your lowest month is in that range, not just the 1,000 kWh column.

Read the EFL for every finalist. Do not rely on the shopping site summary alone. Download the actual EFL and confirm whether a minimum usage fee exists, what the threshold is, and how much it costs.

Factor in contract length and early termination fees. A plan with no minimum usage fee but a high early termination penalty has its own risks. The EFL and Terms of Service will state both.

Use a comparison tool. ElectricRates.org aggregates active plans across Texas TDU territories and lets you sort by the rate that matters most at your actual usage level.

The PUCT requires every REP to disclose minimum usage fees in the EFL before enrollment. If a fee was not disclosed and appears on your bill, you have grounds to file a complaint. The PUCT customer protection line and the official complaint portal handle disputes between customers and REPs.

Texas also gives customers the right to switch REPs at the end of a contract term without penalty, and in some cases during the contract if you are willing to pay any stated early termination fee. If you discover that a minimum usage fee is costing you more than expected, you are not locked in permanently. Comparing alternatives takes about ten minutes on powertochoose.org or ElectricRates.org.

One thing Texas does not have: a default utility supply rate to fall back on. If your REP contract ends and you have not switched, you may be moved to a Provider of Last Resort rate, which exists for emergencies and is not designed as a long-term option. Staying proactive about your plan is the only protection available.

A minimum usage fee in a Texas electricity plan is not a scam, but it is a cost that catches low-usage customers off guard with regularity. The EFL makes it discoverable before you sign. Your own usage history makes the risk calculable before you commit.

For anyone in an Oncor, CenterPoint, AEP Texas, or TNMP service area who uses under 1,000 kWh regularly, confirming whether a minimum usage fee exists on any plan under consideration is worth five minutes of reading. The difference between paying the median market rate and finding a plan structured for your actual usage can be meaningful over the course of a year.
