Right next to it on the list
A rank or two either side of the Antarctic Star KS-40R: Marvel MPWC415-SG31A ($39/yr, 205 kWh/yr), then BANGSON US-BSR-003 ($39/yr, 206 kWh/yr).
Within the Antarctic Star lineup
The Antarctic Star KS-40R is the only refrigerator from Antarctic Star that ENERGY STAR currently certifies, so there's no same-brand model to weigh it against here, only the full refrigerator category.
Antarctic Star KS-40R over 13 years
NAHB's Study of Life Expectancy of Home Components puts a typical refrigerator's service life at 13 years; run the Antarctic Star KS-40R that long and it costs about $503 in electricity, on top of whatever it cost to buy.
