GE GDP66***N*** against the category
That's 3.4% above the dishwasher category average of 232 kWh/yr, and ranks 538 of 737 certified dishwashers for annual running cost, 1 being cheapest. The category average comes from every dishwasher ENERGY STAR currently certifies (737 models), not an outside benchmark, about $2/year above that average at the national rate. See the methodology page.
What sits beside it in the ranking
GE GDP67***V*** ($45/yr, 240 kWh/yr) costs a little more to run than the GE GDP66***N***. GE GDP64***N*** ($45/yr, 240 kWh/yr) costs a little less.
Same brand, different models
GE makes 41 ENERGY STAR certified dishwashers; this one ranks 23 of 41 for running cost, between the brand's cheapest, the GBF180S*M*** at $44/yr, and its priciest, the UDT16***V*** at $45/yr.
What this adds up to over time
NAHB's Study of Life Expectancy of Home Components puts a typical dishwasher's service life at 9 years; run the GE GDP66***N*** that long and it costs about $406 in electricity, on top of whatever it cost to buy.
Shopping for a new one
The GE GDP66***N*** is already efficient for its category at $45/year. If you're shopping and comparing options, this is roughly what a well-chosen new dishwasher costs to run.
Compare current ENERGY STAR certified dishwashers before buying.
Protecting what you have
At $45/year just to run, a dishwasher is worth protecting against an unplanned repair bill on top of that.
Sourcing
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. At rank 538 of 737 for running cost, see the dishwasher category page for the rest of the field, or the guide to how much your state matters.
