Welcome to Heart of Texas Electric's Rates page, a one-stop-understanding on how we calculate your electric bill each month. From Appliance Power Costs to our Rates Schedule and beyond, it's all here for you.

Simply, Heart of Texas Electric Cooperative only charges you for the amount of electricity you use.

We calculate your bill by multiplying the amount of electricity you use (measured in kilowatt-hours) by the price of electricity (charge per kilowatt-hour).



Determining how much electricity your appliances and home electronics use can help you understand how much money you are spending to use them. Most appliances and other electrical equipment have a nameplate that indicates the power requirements.

Once you have your data, calculate the cost of use with this formula: 

Multiply the device's wattage by the number of hours the appliance is used per day and divide that by 1000. Take that number and  multiply it by your kWh rate.

For single phase equipment (any residential equipment):

  • Watts = volts x amps

For three phase equipment (found in some commercial and most industrial equipment):

  • Watts = volts x amps x 1.732 (1.732 is the square root of 3)

To determine the cost of running an appliance, use these formulas:

  • Wattage x Hours Used / 1000 = kWh
  • kWh x cost of electricity = cost

What is PCRF?
Power Cost Recovery Factor "PCRF" is the portion of your bill that will vary monthly based on the current power, transmission and substation cost versus the established cost at the time of our most recent cost of service study.

What is SCRF?
Securitization Cost Recovery Factor "SCRF" is a billing component required to recover monies used to service the debt incurred due to the extraordinary wholesale power cost from Winter Storm URI.

Residential/General Service Charge

The Residential Service line will show the local costs the cooperative incurs for distributing power from the substation to your meter. This section will include an availability charge. The availability charge covers the fixed costs of having poles, lines and meters in place.

Availability Charge

The availability charge is a monthly charge that HOTEC members pay to help cover the basic cost of bringing electricity to their location. It covers some of the expenses the cooperative incurs regardless of how much electricity is sold. The charge helps cover such things as:

  • On-going operation and maintenance of the electrical distribution' system required to bring you electricity at the flip of a switch (hence the name, availability charge);

  • Annual depreciation of these facilities;

  • Principal and interest payments on the long-term debt to build the facilities originally;

  • Expenses related to customer accounting, meter reading, and billing.

Because all cooperative members benefit from having reliable electric service available when they need it, the availability charge allows everyone to pay a share of the basic costs.

Members sometimes ask why HOTEC's availability charge is higher than neighboring electric utilities. It's because of our low consumer density; HOTEC serves an average of six customers per mile of line. Compare this to a city where the average density is easily more than 30 customers per mile of line. It is always more economical to serve areas of higher density. However, HOTEC's average rates remain competitive with those neighboring utilities.

HOTEC serves a diverse membership. Some of our members use a lot of electricity all year long, and some may use electricity only one or two months per year. Whether you use a lot or a little, the cost of getting electric power to your location remains the same. And that is why your electric bill has two separate charges: the availability charge to cover basic costs, and the per kWh charge for the actual amount of electricity consumed.

We hope this brief explanation helps answer your questions about the availability charge portion of your electric bill. Please call us if you have any billing questions.

Wholesale Power Cost

The Wholesale Power Cost line will show the cost of power purchased by the power supplier to Heart of Texas Electric Cooperative, which includes generation, transmission, and independent system operator (ISO) fees.
