How to understand your monthly electric bill

Learning to read your electricity bill can help you understand your energy usage and how your monthly statement is calculated.

Your Texas electricity bill has three key elements: your electricity rate, the Utility Distribution Company (UDC) or Transmission and Distribution Utility (TDU) charge, and taxes. Your chosen plan type will influence how stable your electricity rate is each month.

Let’s dive into what your monthly electric bill in Texas will look like. Depending on your energy provider, your bill may look slightly different from this sample bill, but the core information should be similar.

Other important terms to know on your bill

kWh (Kilowatt-hour): This is the standard measurement used for electricity consumption. It is equal to 1,000 watt-hours.

UDC, TDU, or TDSP delivery charge: This charge covers the cost of moving electricity from the energy plant to your home.

Public Utility Commission of Texas (PUCT): Texas’ regulatory agency focused on several utiities, including electricity and water.

Electricity bill charges

Your electric bill will include several charges. Here is an explanation of each charge.

1. Electric supply charge

The supply charge makes up most of your bill. This charge notes the price of electricity consumed in kWh, which is calculated using your energy plan’s rate. If you have a variable-rate plan, you may experience fluctuations in your electricity rate each month due to seasonal demands.

2. Market charges

These charges depend on changes in the electricity market. They help to keep the grid reliable and balance supply and demand.

3. UDC Charge

This stands for “Utility Distribution Company,” which is the company that delivers electricity to your home. Every household in the utility company’s service area will be charged the same amount, regardless of their REP. Sometimes, these are listed as TDU or TDSP charges.

4. Taxes

This is where you will find state and city taxes. You may also find taxes from MGRT or PUCA. MGRT is the “Miscellaneous Gross Receipts Tax,” which is from your utility company. PUCA, or the “Public Utility Commission Assessment,” is a charge from the PUCT. Every household in your utility’s service area will pay the same amount for MGRT and PUCA.

Check your usage levels from previous months to determine if it has increased. If it has, you can find ways to cut down on consumption. Seasonal energy demand can also increase your bill if you’re enrolled in a variable-rate plan. Contact your electricity supplier if you do not understand the charges on your bill.

Your electricity bill is calculated by adding your electricity rate, taxes, and the UDC or TDU delivery charge.
