Seattle City Light: questions
Does Seattle City Light have peak hours?

1,000 miles a month in a Tesla Model Y Long Range AWD (275 kWh from the wall, EPA 27.5 kWh/100 mi) at 7.2 kW, added to a typical Washington home’s use, on each plan’s cheapest start hour versus plugging in at 6 pm. Averaged over the year.

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 14.74¢ per kWh in 2025 (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.
