Those 65 kWh are billed at 11.3¢–19.1¢, against a 18.7¢ whole-bill average on the median plan: they land in the last tier the household reaches, so the average rate understates them by up to 0.4¢ per kWh.
What Oregon homes use
EIA's 2020 residential survey found 65 kWh a year across 287 sampled homes that run one, near the national 69 kWh. The middle half spans 38 kWh to 80 kWh, so a washing machine varies by 42 kWh between one household and another.
The washer's own motor and controls. Heating the water is billed to the water heater, not here. That average covers homes with a washing machine — 90% of homes here.
That makes a washing machine about 1% of the electricity an Oregon home uses. The remaining 11,067 kWh is what a washing machine is billed on top of, and on a tiered or time-of-use plan that is what sets the rate it meets.
Light and heavy use of a washing machine
A household in the lighter quarter runs a washing machine for 38 kWh a year and pays $4.28 on the cheapest plan. One in the heavier quarter runs it for 80 kWh and pays $9.05 — $4.77 more for a washing machine on the same tariff.
