Right next to it on the list
A rank or two either side of the Comfee CERM18B1A**: Comfee CERM18B0A** ($39/yr, 207 kWh/yr), then Criterion CCR17CE1B ($39/yr, 207 kWh/yr).
Within the Comfee lineup

What this adds up to over time
NAHB's Study of Life Expectancy of Home Components puts a typical refrigerator's service life at 13 years; run the Comfee CERM18B1A** that long and it costs about $506 in electricity, on top of whatever it cost to buy.
Shopping for a new one
Efficient as certified refrigerators go, $39/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
$39/year to run is the predictable cost of the Comfee CERM18B1A**; a protection plan covers the unpredictable one, a repair bill.
