What does Schedule 1 cost a year?

Family home

Home with an EV

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.

off-peak10.18¢ up to 400 kWh13.13¢midnight–midnight, October–May

Plus a fixed charge of $12.16 per month.

Should you be on Schedule 1?

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 $162 and February about $79. That $83 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 400 kWh each month are billed at 11.5¢; past that line the rate steps up to 14.8¢ — 29% 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 $146 a year in fixed fees. On the apartment above that is 22% 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 PacifiCorp’s other plans

Everything below stays inside Utah. Your zone is set by where you live, not by anything you can pick, so a cheaper plan in a different zone is not an option you have.

Measured against the other residential plans this utility files, a family home lands 1st cheapest of 2 — nothing else here beats it for that household.

Who can be on PacifiCorp’s Schedule 1 (Residential Service - Single Phase, single family)?

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

Availability: At any point on the Company's interconnected system where there are facilities of adequate capacity. Application: This Schedule is for alternating current electric service supplied at approximately 120 to 240 volts through one kilowatt-hour meter at a single point of delivery for all service required on the premises for residential purposes.
