N2 - Accurate prediction of the future electricity consumption is crucial for production electricity management. Since the storage of electrical energy is very difficult, reliable and accurate prediction of power consumption is important. Different approaches for this purpose were used. In this paper, Grey model (1,1) based on grey system theory has been used for forecasting results. Annual electricity consumption and forecasting data in Mazandaran were used as our case study. Root mean squared error, Mean absolute error and Mean of average percentage error accuracy testing results show that GM(1,1) is outperformed compared with model fitting and model forecasting. M3 ER -
