Right next to it on the list
A rank or two either side of the OMNImax 3750-247: OMNImax 3750-001 ($103/yr, 550 kWh/yr), then Seasons MSBF18**** ($103/yr, 550 kWh/yr).
Within the OMNImax lineup
Ranked 15 of OMNImax's 16 certified refrigerators, this sits between the 3730-937 ($40/yr, the brand's cheapest) and the 3760-675 ($111/yr, its priciest).
Cost over its typical lifespan
NAHB's Study of Life Expectancy of Home Components puts a typical refrigerator's service life at 13 years; run the OMNImax 3750-247 that long and it costs about $1,344 in electricity, on top of whatever it cost to buy.
Is it worth replacing?
Running above the category average, $103/year is exactly the kind of number that makes a newer, more efficient model pay for itself faster.
Worth comparing a few current certified models before deciding.
If you're keeping it
At $103/year just to run, a refrigerator is worth protecting against an unplanned repair bill on top of that.
