What is the FIS?
The Fridge.com Intelligence Score — a 0–100 rating of how well each U.S. state, city, and ZIP code supports efficient, affordable kitchen operation, built from electricity rates, climate, and local incentives.

Anatomy of a score
Every U.S. state, city, and ZIP code gets the same treatment: three measurable inputs, weighed into one 0–100 number a shopper can act on.
Input · ratesEIA electricity-rate context
Input · climateClimate zone
Input · incentivesVerified rebates & recycling programs
OutputFIS 0–100 — higher is cheaper, easier cold storage
The inputs are re-checked as federal data and incentive programs change, so a place’s score can move — see any location’s current number in the Local Fridge Finder.
A score, not an identifier
The other three Fridge.com systems are permanent identifiers — the FIN names an appliance, the FPN a part, the FFN a filter, each assigned once and never changed. The FIS is deliberately different: an identifier names a thing forever, while a score judges a place today. Mixing the two is how ratings get mistaken for identity, so Fridge.com never does — products never carry an FIS, and product pages report verified specifications, certified energy data, and real price history instead of a synthesized number.
What feeds the score
The FIS is computed from U.S. Energy Information Administration electricity-rate context, climate zone, and verified local incentives — utility rebates and recycling programs among them. Because those inputs move, the score can move with them: a state that adds a rebate program or sees rates fall supports cheaper cold storage than it did before, and its FIS says so.
Explore the rankings in the Local Fridge Finder — every state, city, and ZIP page carries its score alongside the electricity rates, rebates, and recycling options behind it. The four systems are always named in the same order: FIN, FPN, FFN, FIS — three permanent identifiers, then this one score.
Where you’ll see it
LOCAL · 01
On every location page
All 50 states, D.C., cities, and ZIP codes carry their FIS in the Local Fridge Finder.
DATA · 02
In the research
Fridge.com rankings and reports — like the Cold Standard city rankings — are built on FIS methodology and its federal inputs.
CONTEXT · 03
Beside real costs
The score never stands alone: each location page shows the electricity rates, rebates, and recycling programs behind it.
NEVER · 04
On a product — never
Products carry identifiers, not scores. A product page reports verified specs and real price history instead.
