Bill stub
The stub lists the payment amount due and the due date. The bill stub should accompany your payment if you mail it or use an SRP PayCenter®.


Bill Example 6

Meter information
This section lists the total energy in kilowatt-hours (kWh) used for the billing period and the current and prior month's meter readings.

Customer Generation Price Plan customers: The "On-Peak kW Max" is your maximum energy demand for the billing period and is used to calculate the demand charge.

Average Demand Price Plan customers: The "On-Peak kW Avg" is the average of your daily maximum on-peak energy demand readings for the billing period and is used to calculate the demand charge. The "On-Peak kW Max" will also be displayed for your reference.

Comparing your monthly usage
This section features a table that compares the number of billing period days, daily average usage (in kWh), daily average costs and average daily temperatures for the current billing month, last billing month and the same billing month last year.


Bill Example 8

Demand history graph
This bar graph displays up to 36 months of on-peak demand usage in kW. Demand is the measure of the maximum rate at which electricity is being used in your home during on-peak hours. Customers on the Customer Generation Price Plan will see up to 36 months of on-peak maximum demand history; customers on the Average Demand Price Plan will see up to 36 months of on-peak average demand history.

This bar graph displays up to 36 months of usage (kWh) history.


Bill Example 10

Customer information
This section includes basic account information. The plan noted is the price plan used to calculate your bill.

Bill Example 11

Total energy consumption
This section displays the current calendar year of energy consumption broken down by month in kWh. Usage includes energy you generated plus SRP energy.


Bill Example 12

Customer generated power
This section displays the energy you produced during on-peak and off-peak hours.


Bill Example 13

Metered energy
This section displays the energy that you purchased from SRP or sold to SRP during on-peak and off-peak hours. Negative numbers show the amount of kWh sold to SRP. The On-Peak kW Max is the maximum demand that occurred during on-peak hours. Average Demand customers will also see the On Peak kW Avg totals in this section, indicating the average of your daily maximum on-peak energy demand readings for the billing period.


Bill Example 14

Energy consumed offset by energy you generated
This section shows the percentage of your energy that was supplied by your system. If you produced more energy than you consumed, then the percentage will exceed 100%, which indicates SRP purchased the excess energy.

Bill terms

Here is an explanation of some of the terms that appear on your bill:

Monthly service charge: This fixed monthly charge covers the costs for billing, collections, metering, customer services and distribution facilities.

Energy (kWh) charge: This is a variable charge to cover the cost to buy or produce the electricity consumed during the billing service period. Additionally, it covers the cost of supplying necessary transmission, generation and distribution capacity to meet customer’s needs. The actual charge to individual customers will vary month to month according to the amount of energy consumed.

Demand (kW): This is a measure of the maximum rate at which electricity is being used during the billing period. Demand is expressed as kW.

Demand (kW) charge: This charge covers some of the costs of supplying transmission and distribution capacity to meet customer’s energy demand. The transmission system includes the towers and high-voltage lines that transmit electricity from the power plants to the distribution system. The distribution system includes the lower-voltage power lines and poles (or underground power lines) and transformers that connect your service to the transmission system. The actual charge an individual customer pays will vary month to month according to the demand the individual places on the system.

Taxes: This refers to applicable city, county and state taxes.
