Textile industries generally consume a significant amount of electricity in their business operations, hence, efforts to reduce their consumption is necessary. This study assesses the energy consumption and energy saving opportunities in a textile company in Indonesia. A structured energy audit using Define-Measure-Analyze-Improve-Control (DMAIC) was implemented in the Spinning department. The evaluation indicates that 80% of the Specific Energy Consumption (SEC) are dominated by the factory air conditioner and chiller which is corresponding to 515 kWh/kg and 219 kWh/kg respectively. The Coefficient of Performance (COP) of the plant cooling system is 7.41 which conforms to the COP national standard. Further energy-saving opportunities include closing the door and other gateways of the air, replacing the refrigerant material from Freon R-134 to Musicool Mc-134, and installing inverter on mist nozzle motor, evaporator pump, condenser pump, and cooling tower.
