What a dishwasher costs to run in Oregon

What a dishwasher costs here

Across 8 plans priced in Oregon, a dishwasher adds $14.54 to $24.72 a year — $1.21 to $2.06 a month. The median plan puts a dishwasher at $21.84 a year.

Cheapest for a dishwasher: Residential Time-Of-Use Service (Rate 7-TOU), Portland General Electric Co. Dearest: Residential Service (Rate 7), Portland General Electric Co.

Those 129 kWh are billed at 11.3¢–19.2¢, 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 0.5¢ per kWh.

What Oregon homes use

EIA's 2020 residential survey found 129 kWh a year across 250 sampled homes that run one, near the national 112 kWh. The middle half spans 62 kWh to 182 kWh, so a dishwasher varies by 120 kWh between one household and another.

The dishwasher's motor, controls and internal heater, including the heated dry cycle where one is used. That average covers homes with a dishwasher — 79% of homes here, against 69% nationally.

That makes a dishwasher about 1% of the electricity an Oregon home uses. The remaining 11,003 kWh is what a dishwasher 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 dishwasher

A household in the lighter quarter runs a dishwasher for 62 kWh a year and pays $6.96 on the cheapest plan. One in the heavier quarter runs it for 182 kWh and pays $20.52 — $13.56 more for a dishwasher on the same tariff.
