See how much saleable production your facility gets from the energy it consumes. Enter total output, rejected units, and metered electricity for the same reporting period. The result shows good-unit throughput per kilowatt-hour, energy used per good unit, and the effect of rejects. Use it to compare like-for-like shifts, lines, or products without confusing gross output with usable output.
This is an energy-intensity productivity measure, not production speed. It is most useful when the meter boundary, product mix, and reporting period stay consistent.
Include all energy inside the chosen process boundary and use the same boundary in every comparison.
With 12,000 total units, 360 rejects, and 18,000 kWh, good output is 11,640 units. Throughput is 0.6467 good units/kWh, or 1.5464 kWh per good unit.
No. This calculator uses good units so the result reflects saleable output.
Only when the units require broadly comparable processing; otherwise compare each product separately.
Use energy and production totals from exactly the same start and end times.
Energy use may grow faster than good output, especially with extra starts, idle time, or rejects.
It accepts kWh. Convert other energy sources to a consistent kWh-equivalent before combining them.
