## 1. Avoidance of Idling

## Example:

Based on Average capacity utilization [ 70% ] on All Compressors

If a conventional compressor is operated at 70% of its maximum capacity, then it idles for up to 30% of the time. [ Note, these idle time you need to pay ], using a quarter of the energy required for a full load.

### This wastes energy.

## Sample Calculation:

Average utilization [ 70% ] of a 75 KW Compressor

=> 70% full load

=> 30% idling with approximately 25 – 30% of full load consumption

## 1. Based on 4000 operating hours per year

4000 hours per year X 30% idle X 25% of 75 KW X electrical cost [RM0.26/kwh]

1200 hours X 18.75 KW X 25 (cent/kwh)

### SAVING = RM 5,625.00 per year

## 2. Based on 8000 operating hours per year

8000 hours per year X 30% idle X 25% of 75 KW X electrical cost [RM0.26/kwh]

2400 hours X 18.75 KW X 25 (cent/kwh)

### SAVING = RM 11,250.00 per year
