Right next to it on the list
A rank or two either side of the Sub-Zero CL3050U**/S/*/*: Miele KFNF 9955 iDE ($105/yr, 556 kWh/yr), then Bosch B30BB130SS ($105/yr, 560 kWh/yr).
Within the Sub-Zero lineup
Ranked 22 of Sub-Zero's 26 certified refrigerators, this sits between the DEU2450R/ADA/* ($30/yr, the brand's cheapest) and the CL4850S/S/* ($140/yr, its priciest).
Cost over its typical lifespan
13 years is NAHB's typical service life for this category; at $105/year, the Sub-Zero CL3050U**/S/*/* adds up to about $1,361 in electricity over that span.
Shopping for a new one
The Sub-Zero CL3050U**/S/*/* 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 $105/year every year.

If you're keeping it
At $105/year just to run, a refrigerator is worth protecting against an unplanned repair bill on top of that.
