This research was conducted to find the best model to predict how many electrical loads in East Kalimantan should be prepared by Indonesian’s State Electricity Company (PT PLN) in order to ensure comfortable for communities on religious holidays. Two sample religious holidays have been taken; Eid al-Fitr and Christmas Day, then the forecasting was carried out using SARIMA model on historical hourly data from 2015-2018. The result of this research shown that the best SARIMA model on Eid al-Fitr is SARIMA (0,2,1)(0,1,0)24 with 16,99% of MAPE and the best SARIMA model on Christmas Day is SARIMA (0,2,1)(0,1,0)24 with 8.68%.of MAPE.]]>
