Right next to it on the list
A rank or two either side of the Summit S4D18PL: Summit S4D18B ($86/yr, 457 kWh/yr), then Summit S4D18SS ($86/yr, 457 kWh/yr).
Same brand, different models

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 Summit S4D18PL that long and it costs about $1,117 in electricity, on top of whatever it cost to buy.
Shopping for a new one
The Summit S4D18PL runs above its category average. If the refrigerator you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $86/year every year.
