Compressor Sequencing Savings Calculator — Annual kWh, Cost & Payback
Compare baseline and optimized compressor package kW at the same demand to estimate annual kWh savings, cost savings, percent reduction and simple payback.
Inputs
Live results
- Power reduction 35 kW
- Annual energy saved 210,000 kWh
- Annual cost saved 1,680,000
- Reduction 19.444444%
- Simple payback 0.53571429 years
Formula and method
savings=(kWbase−kWopt)×hours; payback=project cost/annual cost savings.
Worked example
Cutting 180 kW to 145 kW for 6,000 h saves 210,000 kWh/year.
Engineering assumptions and limits
- Compare power at equivalent delivered flow and pressure.
- Tariff excludes demand charges unless folded into the entered effective rate.
Frequently asked questions
What does this Compressor Sequencing Savings Calculator calculate?
Compare baseline and optimized compressor package kW at the same demand to estimate annual kWh savings, cost savings, percent reduction and simple payback.
Can I use this for final equipment selection?
Use it for transparent engineering screening. Final selection must be checked against vendor curves, operating envelopes, applicable standards and site measurements.
Why are intermediate results shown?
They expose unit conversions and governing loads so unrealistic assumptions are easier to catch.
