What a dishwasher costs here
Across 10 plans priced in New Jersey, a dishwasher adds $7.92 to $31.48 a year — $0.66 to $2.62 a month. The median plan puts a dishwasher at $16.86 a year.
Cheapest for a dishwasher: RS-TOU-3P - Residential TOU 3 Period Service, Public Service Elec & Gas Co. Dearest: RS - Residential Service, Public Service Elec & Gas Co.
Those 115 kWh are billed at 6.9¢–27.4¢, against a 16.7¢ 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 10.7¢ per kWh.
What New Jersey homes use
EIA's 2020 residential survey found 115 kWh a year across 345 sampled homes that run one, near the national 112 kWh. The middle half spans 39 kWh to 162 kWh, so a dishwasher varies by 123 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 — 69% of homes here.
That makes a dishwasher about 1% of the electricity a New Jersey home uses. The remaining 8,190 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 39 kWh a year and pays $2.68 on the cheapest plan. One in the heavier quarter runs it for 162 kWh and pays $11.17 — $8.49 more for a dishwasher on the same tariff.
