How Seattle City Light’s plans work

Schedule RSC (Residential: City Default). One price per kWh at every hour, all year: 13.4¢. Shifting use to other hours changes nothing on this plan; using less is the only lever. Fixed charge: $12.01 a month.

Prices on this page are all-in per kWh, before taxes: base rates, supply and every per-kWh rider in the utility’s current tariff sheets. Your bill shows them as separate lines, and riders can change between tariff revisions.

As a cross-check, Seattle City Light billed its residential customers an average of 14.09¢ per kWh in 2024 (revenue ÷ sales, EIA-861). A plan taken from URDB is shown only if its all-in price is consistent with that figure, adjusted for Washington’s price change since.
