Abstract: Energy conservation is a most talked subject in the today’s world because energy consumption in various industries in India is a great issue. The standard induction motors in a process plant consume large amount of energy due to low efficiency. To save energy consumption in a process plant, the use of energy efficient motors are chosen over standard induction motor. Energy efficient motors have better efficiency and power factor than standard induction motors. The use of energy efficient motors reduces energy consumption of the plant. The plant under study has 40 motors of different ratings. The work presented in the paper examines the usage of extra energy in various standard induction motors in a process plant and encourage the use of energy efficient motors over standard induction motors. For this objective, a comparison of standard induction motors with energy efficient motors based on efficiency, (kW) motor input power, (kVA) apparent power, power factor, energy consumed (kWh) according to running hours in a year and current. The payback period for energy efficient motors has also been calculated. In the end the study found that replacing standard motors with energy efficient motors is better and overall plant motor load also reduces.
