What does E-27P Tier 2 SRP Residential Demand Price Plan Pilot - Pilot Price Plan for Residential Demand Rate Service cost a year?
| Household | Uses | Per year | Works out to |
|---|---|---|---|
| Apartment One or two people, no central air, no electric heat | 4,866 kWh | $666 | 13.7¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $957 | 10.1¢ / 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.

Should you be on E-27P Tier 2 SRP Residential Demand Price Plan Pilot - Pilot Price Plan for Residential Demand Rate 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 $360 a year in fixed fees. On the apartment above that is 54% of the whole bill; on the house with a car charging in it, 31%. 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 $104 in July and $69 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.
How it compares to Salt River Project’s other plans
Measured against the other residential plans this utility files, a family home lands 4th cheapest of 37. The cheapest option, E-27 Tier 1 SRP CUSTOMER GENERATION PRICE PLAN FOR RESIDENTIAL SERVICE (Amp Service 0-225), would run about $120 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 $422 less per year (31%). 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.
