Salt River Project rate plans

How much does the plan you pick actually matter here?

Run the same three-bedroom house with central air through every plan Salt River Project files, and the bill lands anywhere between $1,360 and $1,640 a year. That $281 spread is not a difference in electricity — it is the same kilowatt-hours, from the same wires, priced under different rules. Nobody sends you a letter when you are on the wrong side of it.

The plan most households land on by default, E-23 Tier 1 BASIC PRICE PLAN FOR RESIDENTIAL SERVICE, comes to about $1,379. The cheapest option here, E-29 Tier 1 SRP Electric Vehicle Price Plan - Residential Electric Vehicle Price Plan, comes to $1,360 — a gap of about $19 a year for a household that never changed a single habit. Whether you can actually capture that depends on when you use power, which is what the calculator below is for.

15 of these 21 plans price by the hour. Those are the ones where moving laundry, dishes, or car charging into the cheap window changes the bill; on the rest, the clock is irrelevant and only the total matters. Which camp you belong in is the first question worth settling, because it decides whether shifting your day is worth anything at all.

Watch the fixed charges too. Across these plans they run from $240 to $480 a year before a single kilowatt-hour is counted. For a small household that difference alone can outweigh the per-kWh price, which is why comparing cents per kilowatt-hour on its own quietly misleads.

How Salt River Project compares across Arizona

Run the same three-bedroom house with central air through its default plan at each of the 3 Arizona utilities we cover, and Salt River Project is the cheapest of the lot at about $1,379 a year; the state median is $1,547. The dearest, Arizona Public Service, charges $1,853 for identical use — a gap set by the address, not by anything either household did.

The other two households tell the same story in different sizes: a small apartment pays about $816 here against a state median of $895, and the same house with an electric car charging overnight about $1,811 against $2,089. Effective rate, fixed charge included, is 14.6¢ per kilowatt-hour for the family home.

Inside Salt River Project itself, the gap between its cheapest and dearest plan for that house is $281 a year — less than the $474 between Arizona's cheapest and dearest utilities. Here the address decides most of the bill; the plan decides the rest.

Before you switch anything

• What is a time-of-use electricity rate?

  The same kilowatt-hour, priced differently depending on when you use it.

• 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.
