What does Schedule 4T - Residential Time of Use cost a year?
| Household | Uses | Per year | Works out to |
|---|---|---|---|
| Apartment One or two people, no central air, no electric heat | 4,866 kWh | $937 | 19.3¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $1,657 | 17.5¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $2,053 | 15.7¢ / 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 | 28.91¢ | 5pm–9pm |
| off-peak | 10.85¢ | 9pm–5pm |
Plus a fixed charge of $14 per month.
Should you be on Schedule 4T - Residential Time of Use?
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 28.9¢ a kWh; at the best hour, 10.8¢ — 2.7× 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 5pm to midnight is about $66 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.
Before a single kilowatt-hour moves, this plan charges $168 a year in fixed fees. On the apartment above that is 18% 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 $186 in July and $108 in February — a $78 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 PacifiCorp’s other plans
Measured against the other residential plans this utility files, a family home lands 16th cheapest of 16. The cheapest option, Schedule 2 Optional Time of Day (Residential Service - Single Phase), would run about $1,555 a year less.
Against Schedule 4 - Residential (Single Phase), which looks like the plan you land on by default, this one comes out $146 more per year (10%). 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.
If this is new to you
- What is a time-of-use electricity rate?
The same kilowatt-hour, priced differently depending on when you use it.
- How to read your electric bill
Four kinds of charge, only two of which you can do anything about.
- 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.
- When should you charge an electric car at home?
The single biggest load most homes can move, and the easiest to automate.
