City of Seattle - (WA) rate plans
9 residential plans are currently open to new customers. None of them price by hour, so shifting when you use power won’t change your bill here.
What does City of Seattle cost at a normal month’s usage?
A household using 1,000 kWh a month pays about $1,821 a year on the cheapest of the 9 plans we can price here — Schedule RSC - Residential: Seattle — and $1,990 on the priciest. Same house, same wires.
| A month of | Cheapest, a year | On which plan | Priciest |
|---|---|---|---|
| 500 kWh | $985 | Schedule RSC - Residential: Seattle | $1,076 |
| 1,000 kWh | $1,821 | Schedule RSC - Residential: Seattle | $1,990 |
| 2,000 kWh | $3,492 | Schedule RSC - Residential: Seattle | $3,819 |
The same plan is cheapest at every level of use here, so the answer does not turn on how much you use. Estimates from the filed tariff, priced hour by hour on a household with central air — not a quote.
How much does the plan you pick actually matter here?
Run the same three-bedroom house with central air through every plan City of Seattle - (WA) files, and the bill lands anywhere between $1,466 and $1,602 a year. That $136 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.
None of these 9 plans price by the hour, so when you use electricity here makes no difference to what you pay — only how much. That narrows your options to two levers: use less, or pick the plan whose fixed charge and tier structure suit your size of household.
Watch the fixed charges too. Across these plans they run from $150 to $162 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.
How City of Seattle compares across Washington
Run the same three-bedroom house with central air through its default plan at each of the 6 Washington utilities we cover, and City of Seattle comes in 5th cheapest at about $1,466 a year; the state median is $1,180. The range runs from $1,020 at PUD No 1 of Cowlitz County to $2,083 at Puget Sound Energy, and since the utility is set by the address, the part of that gap you can act on is the plan, not the company.
The other two households tell the same story in different sizes: a small apartment pays about $827 here against a state median of $791, and the same house with an electric car charging overnight about $1,974 against $1,508. Effective rate, fixed charge included, is 15.5¢ per kilowatt-hour for the family home.
Inside City of Seattle itself, the gap between its cheapest and dearest plan for that house is $136 a year — less than the $1,063 between Washington's cheapest and dearest utilities. Here the address decides most of the bill; the plan decides the rest.

Same usage, different plan
$143a year
That is the gap between the cheapest plan you could be on — Schedule RSC - Residential: Seattle — 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.
