The state framework sets the default. Where UNS (UniSource Energy Services) pays something different, the utility tariff governs and is what the card above reports.
| Compensation mechanism | Net billing. Exported energy is purchased at the RCP export rate; there is no netting of imports against exports. Retail-rate net metering is closed to new residential solar customers. |
|---|---|
| Export rate | Set per utility, not statewide. APS: $0.05554/kWh. TEP: $0.0513/kWh, with $0.0462/kWh pending for October 1, 2026. The rate a customer receives is the tranche in effect when they applied to interconnect, locked for 10 years. |
| Rate effective | APS: September 1, 2026 through August 31, 2027 (Tranche 2026). TEP: October 1, 2025 through September 30, 2026, with the next rate effective October 1, 2026. |
| Credit rollover | Yes. A bill credit larger than the customer's monthly bill is applied to the next monthly bill, and to subsequent bills if necessary. |
| Credit expiration | Balances are settled annually rather than forfeited. APS: after the December bill, credits over $25 are refunded by check; smaller balances carry forward to the following year. TEP: on the October bill (September usage), balances over $10 are paid out; smaller balances carry forward. |
| Annual true-up | APS: annual settlement after the December bill. TEP: annual settlement on the October bill, covering September usage. |
| Aggregate program cap | No statewide aggregate program cap; APS Rate Rider RCP and TEP Rider-14 establish utility-specific customer eligibility and annual RCP export-rate tranches, not a statewide enrollment limit. |
| Program status | Open to new applicants. Rate Rider RCP and TEP Rider-14 set no enrollment cap or aggregate program limit; the annual tranche step-down is the mechanism that reduces compensation over time. |
| Grandfathering | Customers who took service before the RCP replaced net metering keep retail-rate netting for 20 years from the date their system was interconnected. Moving from a grandfathered net metering rider to the RCP rider is permitted but one-way: the customer cannot switch back. Increasing system capacity by 10% or 1 kW-ac, whichever is greater, ends the locked RCP rate. |
| Regulator | Arizona Corporation Commission for APS, Tucson Electric Power, and UniSource Energy Services. Salt River Project is not ACC-regulated and sets its own solar price plans. |
| Governing rule | FPA tariff filings rather than statute: APS Rate Rider RCP (A.C.C. No. 6248, Revision No. 11) and TEP Rider-14 (RCP-PRS). Generators must also meet the Arizona Administrative Code Distributed Generation Interconnection Requirements. |
| Pending change | TEP's next RCP of $0.0462/kWh is listed as Pending in TEP's Statement of Charges, effective October 1, 2026, subject to ACC approval. TEP applied on May 1, 2026; the Utilities Division filed a Memorandum and Proposed Order on August 27, 2026 and the matter appeared on the ACC's September 10, 2026 Open Meeting agenda. |
