Note: Salt River Project (SRP) modified its existing net-metering program for residential customers in February 2015. These changes are effective with the April 2015 billing cycle.

Residential customers that generate part of their electricity requirements on-site are billed under SRP's Customer Generation Price Plan (Schedule E-27). Customers that have purchased their distributed energy system or signed a lease agreement before December 8, 2014 may keep their original net metering rate plan for 20 years, however.

Under the self-generation plan, customers pay a fixed monthly service fee based on the size of their electricity service and a grid, or demand, charge based on the customer's maximum energy usage during peak electricity times. Energy charges per kilowatt hour (kWh) are lower under the customer generation plan than under the standard residential rate plans.  See SRP's website and the rate schedule for more details.

The previous net metering rate schedule is available to customers who purchased their distributed energy system or signed a lease agreement before December 8, 2014. Eligible systems are photovoltaic (PV), geothermal, or wind systems up to 300 kilowatts (kW) in AC peak capacity. The kWh delivered to SRP are subtracted from the kWh delivered from SRP for each billing cycle. If the kWh calculation is net positive for the billing cycle, SRP will bill the net kWh to the customer under the applicable price plan, including Standard Price Plans E-21, E-23, E-26, E-32, E-36, E-47, E-48, E-61, E-63, E-65 and E-66, for which they take service. If the kWh calculation is net negative for the billing cycle, SRP will carry forward and credit the kWh against customer kWh usage on the next monthly bill. However, if the kWh is net negative at the end of the April billing cycle, SRP will credit the net kWh from the customer at an average annual market price. No credits will be carried forward to the May billing cycle.

The Arizona Corporation Commission (ACC) adopted net-metering rules in October 2008. However, the state's rules do not apply to SRP customers.
