Turn a production period’s energy use into the key performance figures: specific energy consumption per kilogram and per tonne, performance against target, and energy cost.
Try sample values — fills the form with the worked example below.
–
SEC (kWh/kg)
–
SEC (kWh/t)
–
Energy cost ($)
Equation: SEC = energy used ÷ production; SEC per tonne = SEC × 1000; energy cost = energy used × price; performance (%) = target SEC ÷ actual SEC × 100.
Method: Specific energy consumption (SEC) as the standard energy key performance indicator for food processing, per ISO 50001 energy management practice.
Assumptions: the energy and production figures cover the same period; the price is the average delivered price per kWh for that period.
Limitations: SEC moves with product mix, throughput and season, so compare like with like; this dashboard does not split energy by fuel or by process step.
Rounding: SEC to 3 decimal places per kg and 1 per tonne, cost to 2; intermediates unrounded.
This is a calculation aid, not a laboratory report — confirm against your accredited method before citing a value.

Worked example: 5000 kWh used for 10 000 kg of production, target 0.45 kWh/kg, price $0.12/kWh: SEC = 0.500 kWh/kg (500.0 kWh/t), energy cost = $600.00, performance 90.0%.
Enter values above to see results.
Track SEC weekly on the same basis: a rising SEC at steady output points to fouling, leaks, idle running or a failing utility. Tool 340 of 500 — GIFSQ
