Salt River Project (SRP) modified an existing net-metering program for residential and commercial customers in November 2013. Net metering is now available to customers who generate electricity using photovoltaic (PV), geothermal, or wind systems up to 300 kilowatts (kW) in AC peak capacity.
The kilowatt-hours (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, Standard Price Plan 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.
An interconnection agreement is required. Click [http://www.srpnet.com/electric/Generators.aspx?res here] for more information.
''The Arizona Corporation Commission (ACC) adopted net-metering rules in October 2008. However, the state's rules do not apply to SRP customers.''
