Energy Saving Opportunities (ESO) are energy (electricity) conservation action opportunities to obtain efficient energy use by reducing various electrical energy losses in all management, from generation, delivery (transmission), to utilization. In Indonesia, the industrial sector, including the garment industry, is a large enough consumer of electrical energy. Electrical energy conservation in industry provides a significant role as an effort to save energy. The efficiency of energy use in the garment industry can be seen from the value of Specific Energy Consumption (SEC) for electrical energy, namely the comparison between electrical energy consumption per production. This thesis examines the opportunities for saving electrical energy on the consumer side (garment industry). The data in this thesis were obtained from a field survey at PT USG Pringapus which was then analyzed to look for opportunities to increase efficiency and improve the quality of electrical power as an effort to conserve electrical energy. The opportunities generated are accompanied by a feasibility study from an economic perspective using the NPV method so that conservation that requires high costs or investment can be known when the payback period is known. By conserving electrical energy, it can produce a decrease in SEC of 12,03% - 21,75%.
