Vehicle-specific pages below apply Conserve 6–9 p.m. and Save (E-28) to each EV’s verified charging-efficiency profile and compare it with the Arizona statewide average.
How SRP differs from the Arizona average
Eligibility / billing boundary: E-28 per-kWh prices are modeled from SRP’s published 2026 rate book. Monthly service charge is separate and is not allocated to marginal EV/appliance/solar use.
The state average is a benchmark, not a substitute for this tariff. A low or high encoded period is a marginal energy price and should not be interpreted as a complete monthly bill unless the page explicitly says whole-bill modeling is supported.
