How much does compressed air cost for powder coating?

Power times hours times tariff. The example's 12 kW coating share across 8 hours at $0.12/kWh is 96 kWh and $11.52 a shift, about a penny per part.

Why is compressed air so expensive per useful unit?

Most of the motor's electricity becomes heat, not air power. The DOE sourcebook puts typical wire-to-air efficiency low enough that air is costly per delivered unit.

How do leaks show up in this calculation?

Invisibly. Leaks raise the draw and the running hours, so an honest meter reading includes them; surveys routinely find 20 to 30% of air feeding leaks.

Should I use nameplate or metered power?

Metered whenever it exists. Compressors cycle below connected load, so nameplate gives a ceiling; a clamp meter over one shift converts it into the bill.

Price the air the coating operation breathes. Enter the compressor power serving coating, the shift's running hours, the tariff and the parts coated.

What this calculator does

Price the compressed air behind the guns, fluidizing and blow-off per shift, per hour and per part.

Formula used

Energy used = compressor power × runtime
Energy cost = energy used × energy rate
Cost per piece = energy cost ÷ parts coated
Hourly cost = compressor power × energy rate

Inputs explained

Compressor Power for Coating: Coating operation's share or a dedicated compressor's metered draw.
Coating Air Runtime: Hours the load runs in the shift, not wall-clock hours.
Energy Rate: Delivered electricity cost, demand and delivery riders included.
Parts Coated: Parts through the booth on the same shift.

How to use the result

Best suited to adding air to the booth cost model, building the leak-survey business case, pricing a pressure-setpoint reduction.
Allocated shares of a house system inherit the allocation's error; metering settles it. Air quality costs are inside the power entry only if their loads are. Demand charges triggered by compressor starts sit outside the kWh model.

Current U.S. benchmarks

As of Jul 2026, industrial electricity averages 9.8 cents per kWh across the U.S. (EIA), up 4.7% from a year earlier. State averages range widely, so plants should confirm against their own tariff.
The producer price index for industrial chemicals stands at 336.006 (BLS, Aug 2026), up 13.3% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 14,543 chemical manufacturing establishments employing about 911,245 workers (Census County Business Patterns, 2023).
