PacifiCorp rate plans

18 residential plans are currently open to new customers. Some charge different prices depending on the hour — which is where most of the savings hide.

How much does the plan you pick actually matter here?

Run the same three-bedroom house with central air through every plan PacifiCorp files, and the bill lands anywhere between $102 and $1,657 a year. That $1,555 spread is not a difference in electricity — it is the same kilowatt-hours, from the same wires, priced under different rules. Nobody sends you a letter when you are on the wrong side of it.

The plan most households land on by default, Schedule 4 - Residential (Single Phase), comes to about $1,511. The cheapest option here, Schedule 2 Optional Time of Day (Residential Service - Single Phase), comes to $102 — a gap of about $1,408 a year for a household that never changed a single habit. Whether you can actually capture that depends on when you use power, which is what the calculator below is for.

8 of these 16 plans price by the hour. Those are the ones where moving laundry, dishes, or car charging into the cheap window changes the bill; on the rest, the clock is irrelevant and only the total matters. Which camp you belong in is the first question worth settling, because it decides whether shifting your day is worth anything at all.

Watch the fixed charges too. Across these plans they run from $86 to $378 a year before a single kilowatt-hour is counted. For a small household that difference alone can outweigh the per-kWh price, which is why comparing cents per kilowatt-hour on its own quietly misleads.

Same usage, different plan

$1,343a year

That is the gap between the cheapest plan you could be on — Schedule 2 Optional Time of Day (Residential Service - Single Phase) — and the priciest. Not by using less power. By being billed differently for the same power.

An estimate, not a quote. Supply charges move month to month, and your real usage pattern is not exactly this one. What it does show reliably is the gap between plans — both are priced off the same assumptions.
