The accepted abbreviation for “Miscellaneous Gross Receipts Tax Reimbursement”. This is the charge assessed to recover the miscellaneous gross receipts tax imposed on retail electric providers operating in an incorporated city or town. The Miscellaneous Gross Receipts Tax Reimbursement is imposed on both utility companies and retail energy providers located in a city or town having a population of more than 1,000 according to the last federal census.

Flat fee applied each month. The fee may vary based on plan enrolled, usage, or size of customer.

For some meters, the actual amount of energy displayed is too large to be registered and the meter shows a fraction of the actual use. A multiplier is then applied to the difference between your present and previous readings to determine your actual energy use.

A non-profit utility owned and operated by the municipality it serves. In Texas, municipally owned utilities may opt into the competitive retail electric marketplace. See also "City-Owned Utility".

The PUC regulates transmission and distribution to ensure the safety and reliability of your electric service.

This is the charge assessed by the Texas Public Utilities Commission (PUC) to recover the statutory fee for administering the Public Utility Regulatory Act. It is equal to 1/6 of 1 percent of the charges on your bill, excluding sales tax.

The total amounts assessed by a TDSP (see Transmission and Distribution) for the delivery of electricity to a customer.

Variable rate plans have no monthly contract or cancellation fee, but the rate you pay per kWh can vary from month to month. Your rate can go up or down based on the market and the discretion of your electric company. Variable plans allow customers to benefit from falling market prices, but they also have an increased risk for higher rates if electricity prices spike due to natural disasters, cold winters, or adverse market conditions.
