What Arizona utilities pay for exported power
Net billing. Utilities regulated by the Arizona Corporation Commission (APS, TEP) credit exports at the Resource Comparison Proxy (RCP) rate, locked for 10 years from interconnection; the rate for new customers can drop by no more than 10% per year. SRP is not ACC-regulated and sets its own export credit.
| Utility | Program | Credit | Source |
|---|---|---|---|
| Arizona Public Service | Rate Rider RCP | $0.0555/kWh | tariff |
| Salt River Project | Customer generation export price plans (E-13 Time-of-Use Export, E-14 EV Export) | $0.0345/kWh | tariff |
| Tucson Electric Power | Rider R-14 Resource Comparison Proxy | $0.0513/kWh | tariff |
