Estimates, not quotes. We run three made-up but realistic households through this tariff hour by hour for a full year — including the way air conditioning loads the afternoon and an EV loads the small hours. Your own bill depends on when you actually use electricity, which is exactly the thing a per-kWh number hides.

Should you be on E-22 Tier 3 SRP EZ-3 Price Plan - PRICE PLAN FOR RESIDENTIAL SUPER PEAK TIME-OF-USE SERVICE?

This is a time-of-use plan, which means the clock decides your bill as much as the meter does. At the worst hour you pay 36.5¢ a kWh; at the best hour, 10.6¢ — 3.4× apart for identical electricity.

That gap is worth real money only if you can move load into it. Every kilowatt-hour a day you shift from 4pm to midnight is about $95 a year. A dishwasher run is roughly 1.5 kWh; an EV commute charge is 8 to 12. If your day is fixed — you are home in the evening and the air conditioner runs when it runs — a plan like this costs you more, not less.

Before a single kilowatt-hour moves, this plan charges $480 a year in fixed fees. On the apartment above that is 46% of the whole bill; on the house with a car charging in it, 24%. Fixed charges are invisible in a cents-per-kWh comparison and they punish small users hardest — if you use very little electricity, the headline rate is the least important number on this page.

Expect the bill to move with the calendar. The same family home costs about $201 in July and $100 in February — a $101 spread driven by heating and cooling far more than by anything you chose. Budget against the July figure, not the average, and a summer bill stops being a surprise.

How it compares to Salt River Project’s other plans

Measured against the other residential plans this utility files, a family home lands 20th cheapest of 21. The cheapest option, E-29 Tier 1 SRP Electric Vehicle Price Plan - Residential Electric Vehicle Price Plan, would run about $272 a year less.

Against E-23 Tier 1 BASIC PRICE PLAN FOR RESIDENTIAL SERVICE, which looks like the plan you land on by default, this one comes out $253 more per year (18%). We infer the default from the tariff structure rather than a flag in the data, so confirm it against your own bill before you switch.

Who can be on Salt River Project’s E-22 Tier 3 SRP EZ-3 Price Plan - PRICE PLAN FOR RESIDENTIAL SUPER PEAK TIME-OF-USE SERVICE?

Eligibility is not our judgement — it is written into the tariff Salt River Project filed. This is what that document says:

Service under this price plan is applicable to a single-family house, a single unit in a multiple family house, a single unit in a multiple apartment, a manufactured housing unit, or other residential dwelling, supplied through one point of delivery and measured through one meter.

Shortened — the clause runs longer in the filing. Quoted from the filed tariff. Your utility decides eligibility, not us; check with them before you switch.
