What does E-23 Tier 3 BASIC PRICE PLAN FOR RESIDENTIAL SERVICE cost a year?
| Household | Uses | A month | Per year | Works out to |
|---|---|---|---|---|
| Apartment One or two people, no central air, no electric heat | 4,866 kWh | $88 | $1,056 | 21.7¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $135 | $1,619 | 17.1¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $171 | $2,051 | 15.7¢ / kWh |
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.
What you actually pay
| Period | Rate | Applies when |
|---|---|---|
| peak | 13.98¢ | midnight–midnight, July–August |
| mid | 12.04¢ | midnight–midnight, May–June, September–October |
| off-peak | 10.97¢ | midnight–midnight, November–April |
Plus a fixed charge of $40 per month.
Should you be on E-23 Tier 3 BASIC PRICE PLAN FOR RESIDENTIAL SERVICE?
The hour of day does not change what you pay here — the month does. Running the same house through the full year, July costs about $194 and February about $106. That $88 swing is part rate and part weather, and it is the reason a budget built on your spring bill will break in July.
Before a single kilowatt-hour moves, this plan charges $480 a year in fixed fees. On the apartment above that is 45% of the whole bill; on the house with a car charging in it, 23%. 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.
How it compares to Salt River Project’s other plans
Measured against the other residential plans this utility files, a family home lands 17th cheapest of 21. The cheapest option, E-29 Tier 1 SRP Electric Vehicle Price Plan - Residential Electric Vehicle Price Plan, would run about $259 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 $240 more per year (17%). 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-23 Tier 3 BASIC PRICE PLAN FOR RESIDENTIAL 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. Service under this price plan excludes resale, sub-metering and standby uses. Tier 3: Applies to any residence with service of more than 225 amps.
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.
If this is new to you
- How to read your electric bill
Four kinds of charge, only two of which you can do anything about.
- Should you switch to a time-of-use electricity plan?
A wide peak-to-off-peak gap is a lever, not a saving. Levers need something to move.
- Why is my electric bill so high in summer?
Usually three causes at once, and only one of them is your air conditioner.
- Why is my electric bill so high? Seven causes, in the order to check them
Seven causes, ranked by how often they are the answer. Only two are about using more.
