What does E-15 Tier 3 CUSTOMER GENERATION AVERAGE DEMAND 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 | $66 | $786 | 16.2¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $90 | $1,077 | 11.4¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $108 | $1,299 | 9.9¢ / 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

Should you be on E-15 Tier 3 CUSTOMER GENERATION AVERAGE DEMAND PRICE PLAN FOR RESIDENTIAL SERVICE?
This plan bills a demand charge on top of the per-kWh rates: a fee tied to your single highest hour of the month. Two homes using the same total electricity can pay very different amounts if one of them runs the dryer, the oven, and the car charger at the same moment. We do not price demand charges yet, so treat every dollar figure on this page as a floor, not a total.
Before a single kilowatt-hour moves, this plan charges $480 a year in fixed fees. On the apartment above that is 61% of the whole bill; on the house with a car charging in it, 37%. 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 $114 in July and $79 in February — a $36 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.

Who can be on Salt River Project’s E-15 Tier 3 CUSTOMER GENERATION AVERAGE DEMAND PRICE PLAN FOR RESIDENTIAL SERVICE (Amp Service 225+)?
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 limited to residential customers with on-site generation who do not purchase all of their energy requirements from SRP. This 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, where the on-site generation is installed.
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.

A dozen brutally expensive afternoons a year, in exchange for a discount on the other 353 days.
- Why is my electric bill so high in summer?
Usually three causes at once, and only one of them is your air conditioner.
