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 electric base rate combines:

  • The Service Availability Charge covers the cost of metering and billing for your address, regardless of consumption.
  • The Energy Charge recovers costs for power plants and other infrastructure based on the amount of electricity you use.
  • The Peak Capacity Charge applies during the months of June through September when an additional charge of $0.0198 is added to bills for every kilowatt hour (kWh) used in excess of 600 kWh.  The Peak Capacity Charge covers the higher costs for electricity CPS Energy incurs during summer months when the demand for electricity is at its highest.

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 charge 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 Plan (STEP)––recovers portion of costs associated with energy efficiency

Costs recovered through the Regulatory Adjustment factor include:

  • Electric Reliability Council of Texas (ERCOT) administrative fee
  • North American Electric Reliability Corporation / Electric Reliability Organization (NERC/ERO) fees
  • Expenditures associated with the ERCOT-wide transmission grid

Other Costs

The City of San Antonio delivers a broad range of services – from waste collection to park maintenance – to you and your neighbors. The fees for many of those services are collected through your CPS Energy bill. For the city government, this is a convenient and efficient way to collect monthly fees. You’ll find a complete list of these fees under “City Services” on the back of your CPS Energy bill. CPS Energy is not responsible for providing these services. They include:

  • Garbage Collection Services costs
  • Brush Fee Environmental Services Fee
  • Environmental Services Fee
