This study presents a risk management of the electric energy consumption in Nakhonratchasima industrial, case study in Thai Sanguan Cassava Starch Co.,Ltd. by AS/NZS 4360:2004 risk management standard. The objective of this study is to reduce the risk of electric energy consumption. Based on the risk inspection, the impact analysis of electric energy consumption is applied to manage an occasion risk. The analyzed risks are consumption risks and device risks. The consumption risks are load factor, the ratio of electric energy consumption to production unit and power consumption of each unbalance phase. The device risks are an efficiency of machinery and equipment, water pump usages, lighting system and air condition system. The results show that the use of machinery and equipment is the highest risk. Load factor, the ratio of electric energy consumption to production unit and water pump usages are ranged in medium risk level, while each phase of electric energy consumption, lighting system and air condition system are in low risk level. As a priority result, machine maintenance is an initial management to decrease the electric energy consumption. For reducing the electric energy demand, work schedule has been rearranged to enlarge the load factor. Operator controlling will reduce the ratio of electric energy consumption to production unit. The inverter, which is used to control motor in water pump usages, also reduce the risk of electric energy consumption. Finally, the low impact factor from lighting and air condition system are neglected.
