Fixed Energy Charge Plan (R-1) Medium Tier 2

Does the hour matter on Fixed Energy Charge Plan? No — one rate, every hour of the year.

  • off-peak17.04¢

There is no peak and no off-peak here: 17.04¢ per kilowatt-hour at 3am is the same as at 6pm, on a Sunday as on a Tuesday, in July as in January. Moving laundry or car charging to another time of day will not change this bill by a cent. What does change it is how much you use, and the fixed charge below, which you pay whether you use anything or not.

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.

Plus a fixed charge of $0.458 per day — so longer months cost more before you use a single kWh.

Should you be on Fixed Energy Charge Plan?

One rate, every hour of the year. That makes this plan predictable and nothing else: there is no cheap window to move laundry or car charging into, and no penalty for running the oven at six in the evening. Predictability is worth something if your schedule is not yours to control — but if it is, a flat rate is the one structure that guarantees you cannot benefit from it.

Before a single kilowatt-hour moves, this plan charges $167 a year in fixed fees. On the apartment above that is 17% of the whole bill; on the house with a car charging in it, 7%. 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 $201 in July and $115 in February — a $87 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 Arizona Public Service’s other plans

Measured against the other residential plans this utility files, a family home lands 1st cheapest of 5 — nothing else here beats it for that household.

Against Time-of-Use 4pm-7pm Weekdays (R-TOU-E), which looks like the plan you land on by default, this one comes out $76 less per year (4%). 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.

Other Arizona Public Service plans

Who can be on Arizona Public Service’s Fixed Energy Charge Plan (R-1) Medium Tier 2?

Eligibility is not our judgement — it is written into the tariff Arizona Public Service filed. This is what that document says:

This rate schedule is available to residential Customers with an annual average monthly energy usage of more than 600 but less than 1,000 kilowatt-hours (kWh) who do not have an on-site distributed generation system. For new customers, initial annual average monthly energy usage will be based on historical energy consumption at the Customer�s site. Annual reassignment will begin with January 2019 bills. Starting May 1, 2018, first-time Customers are not eligible for this rate for a period of ninety (90) days from the date service begins. After this initial 90-day period, qualifying Customers may move to this rate at any time but must remain on this R-Basic rate schedule for at least twelve (12) consecutive months before moving to another residential rate schedule for which the Customer may qualify.
