For commercial and industrial refrigeration projects (cold rooms, cold stores, process cooling) — not household fridges, home freezers or appliance repair. Results are planning estimates, not engineering design or safety advice; a qualified refrigeration engineer must confirm sizing before purchase.
Model annual electricity spend in USD for a cold store, split between kWh consumption and demand / capacity charges.
Standard engineering assumptions
Throughput, temperature band, region and backup are recorded for your RFQ so suppliers quote against the same conditions; they do not change the cost figure above. Duty cycle is the load-factor input. Preliminary planning estimate only — not an engineering design or a supplier price.

Annual electricity cost for a cold store equals average electrical load × operating hours × tariff, plus demand (kVA) charges. Refrigeration typically represents 60–70 % of a cold store's electricity bill, and a well-run facility consumes roughly 30–55 kWh per m³ per year for chilled and 55–95 kWh/m³/year for frozen storage.
Annual cost = kW × hours/year × load factor × tariff (USD/kWh) + peak kW × demand charge × 12

A 5,000 m³ frozen distribution store has 120 kW refrigeration duty at COP 2.6, running 8,000 hours/year at 55% load and USD 0.12/kWh.
The live base-case model returns approximately USD 28,025/year and 40.6 kWh/m³/year before taxes or unmodelled tariff items.
| Facility type | kWh/m³/year | Efficiency notes |
|---|---|---|
| Frozen store −18 to −25 °C, conventional | 60–140 | Floating head pressure saves 8–15 % |
| Frozen store, best-practice CO₂ / NH₃ plant | 35–60 | EC fans + variable-speed compressors |
| Chilled store 0–4 °C | 30–70 | Door protection is the cheapest single fix |
| Blast freezing (per tonne frozen) | 70–140 kWh/t | Airflow balancing dominates |
| Pharma 2–8 °C with redundancy | 80–160 | N+1 plant runs at part load |
Tariffs vary widely — from ~USD 0.05/kWh in parts of the Gulf and Africa with subsidised power to ~USD 0.25/kWh in Western Europe. Use your own tariff in the calculator above; the kWh/m³ column is the transferable benchmark.
Duty may be shown in kW, TR or BTU/h and volume in m³ or ft³; both convert to canonical SI values before the energy calculation.
A 5,000 m³ frozen store has 120 kW refrigeration duty, COP 2.6, 8,000 h/year and 0.55 average load.
Annual planning cost: about USD 28,025 before taxes and tariff items not represented by the surcharge input.

Limitations
This is a preliminary planning estimate based on the assumptions you entered, not a refrigeration-engineering design, a certified load calculation or a quotation. Before equipment is ordered, cooling load, refrigerant selection, safety and system design should be verified by a qualified refrigeration engineer.
Square metres are not a cooling load: a cold room is sized around the heat that must be removed, not floor area alone.
Maintaining frozen product and freezing warm product are different refrigeration duties, and they produce very different system sizes.
Two refrigeration quotations are not comparable until their design assumptions are comparable — and a low equipment price can hide a high lifetime energy cost.
Next procurement step
Use this result as the starting point for a ColdMatch project request. Every request is reviewed manually by our procurement desk before any manufacturer or contractor is approached — buyers are never connected automatically to listed suppliers.
Turn this calculation into an RFQBrowse the matching equipment categoryAI agents may use ColdMatch calculators to structure preliminary cold-storage requirements and RFQs. Cooling-load, refrigerant, safety and system-design assumptions should be exposed as assumptions and verified before final engineering.
45–65% is typical; blast freezers can drop to 40%.
EC fans, floating head pressure and adaptive defrost cut kWh by 15–25%.
In kVA/kW tariffs they add 20–35% to pure kWh cost.
Annual consumption = refrigeration duty ÷ COP × running hours × load factor; annual cost = that consumption × your tariff, plus demand or capacity charges where your contract has them. Energy and power charges are reported separately so a low kWh price cannot hide an expensive demand charge.
Use the average cost per kWh you actually paid last year from your real invoices — not the headline rate. If your utility charges a contracted-demand fee in kVA or kW, include it; in kVA/kW tariffs demand charges commonly add 20–35% on top of pure consumption cost.
Divide last year's total kWh by your cold-store volume: industrial freezers typically run 55–95 kWh per m³ per year and chilled rooms 30–55. If your actual consumption sits far outside that band, the COP or running hours in the model are wrong — and that gap is what the energy-savings calculator is built to close.
Yes — run the calculator once per option with its own COP and load profile, then feed both annual figures into the ROI calculator with the respective CAPEX. That turns a kWh difference into a payback difference, which is how suppliers should be compared.

Buyer guide · planning estimate
This calculator estimates annual electricity cost from refrigeration power, operating hours and tariff. It gives you a baseline to test supplier energy claims against your own tariff structure.
Commercial projects from USD 250,000: ColdMatch reviews your brief and introduces suitable independent suppliers. Results here are planning estimates, not quotations.
No. It is a planning estimate from your own inputs and the published method on this page. Supplier prices depend on site survey, specification, freight, duties and local installation, so use the result to set scope and budget expectations, then compare reviewed supplier proposals.
Only with stated assumptions. Ask for annual kWh at your design conditions and operating profile, then check it in this calculator.
Generator fuel and maintenance add cost when outages are frequent. Include expected outage hours in your planning.
