Cold Storage Energy Cost Calculator
Cold storage is energy-intensive; electricity is the single largest operating cost.
Annual energy cost
$742,800
Cost / sqft
$3.71
Total kWh / year
6,190,000
How the math works
Total kWh = frozen sqft × kWh/sqft + cooler × + dry × 5. Cost = kWh × rate.
80k×55 + 70k×22 + 50k×5 = 6.19M kWh × $0.12 = $743k = $3.72/sqft.
How to Use
- Enter total sqft.
- Enter frozen % of sqft.
- Enter cooler % of sqft.
- Enter kWh/sqft frozen.
- Enter kWh/sqft cooler.
- Enter electricity rate.
- Read annual energy cost.
Frequently Asked Questions
Energy intensity?
Freezer (-10 to 0°F): 40-75 kWh/sqft/yr. Cooler (32-40°F): 15-35 kWh/sqft/yr. Blast freezer: 100-150 kWh/sqft/yr. Dry storage (60-75°F): 3-8 kWh/sqft/yr. Cold storage uses 10-20× the energy/sqft of warehouse. Typical facility: $4-12/sqft annual energy cost (freezer), $2-6 (cooler), $0.50-1.50 (dry). Passthrough to tenants via storage fees.
What drives efficiency?
Insulation R-value (R-30 to R-60 for coolers, R-40 to R-70 freezers). Dock seal quality (loading dock infiltration is major heat gain). Door automation (high-speed roll-up, 2-5 sec open/close). Compressor efficiency (variable-frequency drive saves 20-40%). Evaporator coils cleaning schedule. Building envelope age (1980s facilities 30-50% less efficient than 2020s). Refrigerant type (ammonia most efficient, CO2 emerging, HFCs declining).
Operating cost breakdown?
Electricity: 45-70% of operating cost (dominant). Labor: 15-25%. Maintenance: 8-12%. Insurance: 4-6%. Property tax: 3-5%. Refrigerant make-up: 1-3%. Total operating cost: $8-20/sqft/year. Rent: $15-40/sqft/yr modern, $10-22 older. Net margin (cold storage operator): 20-35%. Major operators: Lineage Logistics, Americold, US Cold Storage.
Peak demand charges?
Commercial electric bill: energy charge ($/kWh) + demand charge ($/kW peak). Cold storage has high demand charge (compressors start/stop). Can add 20-40% to total electric bill. Mitigation: compressor sequencing, thermal storage (ice-bank), load-shifting (batteries). Utility incentives for demand reduction: $100-400/kW avoided. VPP (virtual power plant) programs: $50-200/kW/yr payment.
