Right next to it on the list
A rank or two either side of the Honeywell HDS18SS: Honeywell HDS18* ($44/yr, 234 kWh/yr), then Kenmore 1460# ($44/yr, 234 kWh/yr).
Same brand, different models
Ranked 2 of Honeywell's 3 certified dishwashers, this sits between the HDS18* ($44/yr, the brand's cheapest) and the HDS24SS-H ($45/yr, its priciest).
What this adds up to over time
9 years is NAHB's typical service life for this category; at $44/year, the Honeywell HDS18SS adds up to about $396 in electricity over that span.
Weighing a replacement
Efficient as certified dishwashers go, $44/year is a reasonable baseline if you're comparing what else is on the market.

If you're keeping it
At $44/year just to run, a dishwasher is worth protecting against an unplanned repair bill on top of that.
Where this number comes from
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Dishwasher category page shows all 737 dishwashers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
