Air Compressor - Power Cost per Year

Yearly power cost for operating an air compressor.

The yearly power costs for operating an air compressor can be calculated

C = Pbhp 0.746 ckWh hyear / μ                                 (1)

where

C = total power costs per year (USD - or actual currency)

Pbhp = compressor power (bhp)

ckWh = cost per kWh (USD - or actual currency)

hyear = operating hours per year (h)

μ = motor efficiency

Power costs count for typical 60-70%, fixed costs counts for typical 10-20% and other costs counts typical for 15-25% of the total operating costs.
