Minimum Usage Fee
Texas Electricity Glossary
A minimum usage fee is an additional charge applied to your Texas electricity bill when your monthly consumption falls below a specified threshold. For example: "$9.95 fee if usage is below 500 kWh." Minimum usage fees are common on plans marketed with very low advertised energy rates — the provider recovers its costs from low-volume customers through this mechanism. They hit hardest on small apartments, energy-efficient households, and vacation properties.
How Minimum Usage Fees Work
The fee appears as a separate line item on your bill when usage falls below the threshold that month. It is effectively a floor on your monthly bill, ensuring the REP collects a minimum revenue per customer regardless of consumption. The fee is charged in addition to the actual energy used — it is not a substitute for the energy charge.
Example: Minimum usage fee impact on a 450 kWh month
Plan: 9¢/kWh energy rate, $9.95 minimum usage fee below 500 kWh
Energy charge: 450 kWh × 9¢ = $40.50
Minimum usage fee: $9.95 (applied because 450 kWh < 500 kWh threshold)
Total energy charge: $50.45
Effective energy rate: $50.45 ÷ 450 kWh = 11.2¢/kWh — 24% higher than advertised
Where to Find Minimum Usage Fees
Minimum usage fees are disclosed on the Electricity Facts Label (EFL). They are often revealed by a high rate at the 500 kWh column — if the 500 kWh rate is dramatically higher than the 1,000 kWh rate, a minimum usage fee is likely the cause. TexasPowerCost.com's calculations incorporate the EFL's 500 kWh price point, which captures the minimum usage fee impact for lower-usage customers.
Plans to Avoid if You Are a Low-Usage Customer
If your household typically uses under 800 kWh/month, prioritize plans with no minimum usage fee (a $0 entry in the fee section of the EFL) or with a low threshold. Prepaid electricity plans and some simple flat-rate plans often have no minimum usage fee — check the EFL before enrolling.

Frequently Asked Questions
What is a minimum usage fee on a Texas electricity plan?
A minimum usage fee is an additional charge applied when your monthly electricity consumption falls below a specified threshold — for example, "$9.95 if usage is below 500 kWh." It is the inverse of a bill credit. Plans with low advertised base rates often include minimum usage fees that significantly raise the effective rate for low-usage customers like apartment dwellers.
Who is most affected by minimum usage fees?
Small apartments (studios, 1-bedrooms), vacation homes, rental properties that are occasionally unoccupied, and energy-efficient households are most at risk. If your typical usage is 400–600 kWh/month, always check the EFL for minimum usage fee thresholds before enrolling.
Are minimum usage fees disclosed on the EFL?
Yes. Minimum usage fees must be disclosed on the Electricity Facts Label. They typically affect the 500 kWh price point significantly — making the 500 kWh EFL rate look very high even though the 1,000 kWh rate seems competitive. Always read the 500 kWh row of the EFL if you are a low-usage household.
