Sugarcane processing industry is believed to consume a high amount of energy through several production stages. Consequently, the cost of energy is considered an important item in total production costs that consuming a detectable part of the company’s annual profits. Energy audit program (EAP) is considered an important pillar to mitigate the high cost production for improving the efficiency of industrial operating conditions. It improves the efficiency of the factory’s components through three scenarios. The first is starting from classifying the utilities inputs and outputs to evaluate energy balance of each equipment. Results indicated that in the first scenario by using steam dairator, the fuel flow rate can be reduced by 189.49 m3/h which raise the energy efficiency by 6.32 %. In the second scenario, boiler blowdown heat exchanger only, flow rate of 166 m3/h of fuel can be saved with 5.52 % increasing in energy efficiency. In the third scenario, mixing between the two previous scenarios will increase the energy efficiency by 22.1 % via saving fuel reached about 664 m3/h. It was found that the suggestive solutions are significantly contributed remarkable improving in the company’s energy efficiency. Consequently, they decrease energy cost items and increase the company’s annual output profits.
