Net metering / billing
Net Billing (RCP)

Under Arizona's net billing tariff (ACC-approved), APS exports earn the Resource Comparison Proxy rate (~6.17¢/kWh Oct 2025–Sep 2026, steps down ~10%/yr); self-consumed solar saves at full retail rate, making consumption-shifting and storage high-value.

Estimates use the average Arizona current utility rate (before solar) of $0.15/kWh (EIA, retrieved Aug 2026) and modeled solar production; individual results vary with your rate, usage, roof orientation, and shading.
