Estimates, not quotes.

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-29 Tier 3 SRP Electric Vehicle Price Plan - Residential Electric Vehicle Price Plan?

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 26.0¢ a kWh; at the best hour, 7.9¢ — 3.3× 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 2pm to midnight is about $66 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 47% of the whole bill; on the house with a car charging in it, 25%. 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 $197 in July and $99 in February — a $99 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 15th cheapest of 21. The cheapest option, E-29 Tier 1 SRP Electric Vehicle Price Plan - Residential Electric Vehicle Price Plan, would run about $240 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 $221 more per year (16%). 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-29 Tier 3 SRP Electric Vehicle Price Plan - Residential Electric Vehicle Price Plan?

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

The E-29 Price Plan is frozen from new participation as of the November 2025 billing cycle and will be eliminated as of the November 2029 billing cycle or, if administrative capability allows, an earlier billing cycle designated by SRP.

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.
