What does 1A cost a year?

HouseholdUsesPer yearWorks out to
Apartment

One or two people, no central air, no electric heat

4,866 kWh$78716.2¢ / kWh
Family home

Three or four people with central air conditioning

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 $12.79 per month.

Should you be on 1A?

This is a time-of-use plan, which means the clock decides your bill as much as the meter does. At the worst hour you pay 13.7¢ a kWh; at the best hour, 9.8¢ — 1.4× apart for identical electricity.

That gap is worth real money only if you can move load into it. Every kilowatt-hour a day you shift from 5am to midnight is about $14 a year. A dishwasher run is roughly 1.5 kWh; an EV commute charge is 8 to 12. If your day is fixed — you are home in the evening and the air conditioner runs when it runs — a plan like this costs you more, not less.

There is a usage cliff to watch. The first 900 kWh each month are billed at 12.6¢; past that line the rate steps up to 21.3¢ — 69% more for every unit after. The last kilowatt-hour of a heavy month is the expensive one, which is why cutting a little off a big month saves more than cutting the same amount off a small one.

Before a single kilowatt-hour moves, this plan charges $153 a year in fixed fees. On the apartment above that is 20% of the whole bill; on the house with a car charging in it, 8%. 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 $188 in July and $90 in February — a $98 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 Public Service Co of NM’s other plans

Measured against the other residential plans this utility files, a family home lands 1st cheapest of 3 — nothing else here beats it for that household.

Against 1A (Residential Service), which looks like the plan you land on by default, this one comes out $194 less per year (12%). 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.
