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.

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.

Which plan would cost you least?

No bill upload, no sign-up. Tell us roughly what you use and what runs on electricity — we price every plan against the same household and show you the gap.

What else runs on electricity

That adds up to 7,914 kWh a year. Compare it to the total on your bill and adjust until it’s close.

Same usage, different plan

$116a 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.
