Base Rate Cost

The electric and gas charges found on your CPS Energy residential bill are made up of base rate components, the fuel adjustment, and the regulatory adjustment.

The formula for the residential base rate combines:

  • The Service Availability Charge, which covers the cost of metering and billing for your address, regardless of consumption
  • The Energy Charge, which recovers costs for power plants and other infrastructure based on the amount of electricity you use.
  • The Peak Capacity Charge, which is added to customer bills to help cover the higher costs incurred by CPS Energy during summer months. Between the months of June and September, an additional charge of $0.0198 is added to bills for every kilowatt hour (kWh) in excess of 600 kWh.

For the natural gas rate, the residential base rate includes just the Service Availability Charge and the Energy Charge. Each of these items is listed on the back of your bill.

Retail rates contain an electric fuel adjustment or gas cost adjustment clause, which provides for recovery of fuel costs.

Electric and gas fuel adjustment factors (listed below) are set each month and may be positive or negative, depending on whether fuel costs for the period are above or below the amount that is built into the base rate. As a result, customers may see a change or a credit on their monthly bill.

For retail customers, the fuel adjustment charge may appear as a charge or a credit on your monthly bill. Here’s what goes into it:

  • Generated Power Costs––fuel costs associated with CPS Energy’s nuclear, coal, and natural gas units
  • Renewable Power Costs––renewable energy purchases of wind, solar, and landfill gas
  • Market Power Purchases––purchases from the open market
  • Save for Tomorrow Energy Program (STEP)––recovers portion of costs associated with energy efficiency

Costs recovered through the regulatory adjustment factor include:

  • ERCOT administrative fee
  • NERC/ERO (Electric Reliability Organization) fees
  • Expenditures associated with the ERCOT-wide transmission grid
