With the rapid growth of yearly peak loads in Beijing, the issue of prediction for yearly peak load had already caught great attention of electric utility. Based on the data of yearly peak load between 1997 and 2002, in this paper Grey wrapping prediction model for yearly peak load had been built according to the occurring characteristic of yearly peak load in Beijing. In comparison with other model, we find that the Grey wrapping prediction model which can meet the practical requirement of electric utility is more reasonable and feasible. Therefore, the Grey wrapping prediction model for yearly peak load gives electric utility some important references to make power load operation schedules, such as arranging properly switching or reserve planning of generation, transmission and distribution systems.
