Schedule 1 (Residential Service - Three Phase, single family)
When does peak hit on PacifiCorp’s Schedule 1? The hour never matters here — only the season. Rates peak June–September.
- peak11.50¢
- off-peak10.18¢
What does Schedule 1 cost a year?
| Household | Uses | A month | Per year | Works out to |
|---|---|---|---|---|
| Apartment One or two people, no central air, no electric heat | 4,866 kWh | $63 | $755 | 15.5¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $116 | $1,398 | 14.8¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $158 | $1,898 | 14.5¢ / kWh |
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.
What you actually pay
| Period | Rate | Applies when |
|---|---|---|
| peak | 11.50¢ up to 400 kWh14.83¢ | midnight–midnight, June–September |
| off-peak | 10.18¢ up to 400 kWh13.13¢ | midnight–midnight, October–May |
Plus a fixed charge of $19.66 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 $169 and February about $86. 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 $236 a year in fixed fees. On the apartment above that is 31% of the whole bill; on the house with a car charging in it, 12%. 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
Measured against the other residential plans this utility files, a family home lands 5th cheapest of 14. The cheapest option, Schedule 36 - Residential Service Optional TOD, would run about $247 a year less.
Against Schedule 4 - Residential (Single Phase), which looks like the plan you land on by default, this one comes out $113 less per year (7%). 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.

Who can be on PacifiCorp’s Schedule 1 (Residential Service - Three Phase, single family)?
Eligibility is not our judgement — it is written into the tariff PacifiCorp filed. This is what that document says:
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 or 240 volts through one kilowatt-hour meter at a single point of delivery for all service required on the premises for residential purposes.

If this is new to you
- Tiered billing for electricity: why the last kWh costs more
A cheap allowance, then a cliff. Where the cliff sits is the whole game.
- 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.
- Why is my electric bill so high in summer?
Usually three causes at once, and only one of them is your air conditioner.
- Why is my electric bill so high? Seven causes, in the order to check them
Seven causes, ranked by how often they are the answer. Only two are about using more.
