What does Schedule 1 - Residential Service cost a year?

Apartment

4,866 kWh$95619.6¢ / kWh
Family home

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 $15 per month.

Should you be on Schedule 1 - Residential Service?

The hour of day does not change what you pay here — the month does. Running the same house through the full year, July costs about $205 and February about $108. That $97 swing is part rate and part weather, and it is the reason a budget built on your spring bill will break in July.

There is a usage cliff to watch. The first 800 kWh each month are billed at 16.8¢; past that line the rate steps up to 18.8¢ — 12% 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 $180 a year in fixed fees. On the apartment above that is 19% 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.

How it compares to Idaho Power’s other plans

Measured against the other residential plans this utility files, a family home lands 2nd cheapest of 3. The cheapest option, Schedule 5 - Residential Time-of-Day, would run about $485 a year less.
