What a dishwasher costs here
Across 5 plans priced in Florida, a dishwasher adds $12.60 to $15.48 a year — $1.05 to $1.29 a month. The median plan puts a dishwasher at $13.80 a year.
Cheapest for a dishwasher: RS Residential Electric, Jacksonville Electric Authority. Dearest: RTR-1 Residential Service TOU, Florida Power & Light Co..
Those 97 kWh are billed at 13.1¢–16.0¢, against a 13.4¢ 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 2.6¢ per kWh.
What Florida homes use
EIA's 2020 residential survey found 97 kWh a year across 515 sampled homes that run one, near the national 112 kWh. The middle half spans 38 kWh to 140 kWh, so a dishwasher varies by 102 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 — 76% of homes here.
That makes a dishwasher about 1% of the electricity a Florida home uses. The remaining 13,893 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.
By provider
On each Florida provider's cheapest plan: Jacksonville Electric Authority, $12.60; Florida Power & Light Co., $13.80.
Florida Power & Light Co. charges $1.20 a year more than Jacksonville Electric Authority on RS Residential Electric for the same 97 kWh.
Light and heavy use of a dishwasher
A household in the lighter quarter runs a dishwasher for 38 kWh a year and pays $4.92 on the cheapest plan. One in the heavier quarter runs it for 140 kWh and pays $18.24 — $13.32 more for a dishwasher on the same tariff.
