How the cost is calculated
Consumption (kWh) = motor kW × running hours × working days × load factor. Cost = consumption × tariff. Load factor is the share of time the machine is actually loaded rather than idling — most plants fall between 60% and 80%.
Variable-speed (VSD) compressors typically save 20–35% on fluctuating loads, and almost nothing on a constant full load.
