A statistic analysis of the time series was made on a computer, and a pattern was identified to possess clear seasonality in anually cycle and linear growth trend. Moreover, in accordance with the two proportions of power consumption and its variance in each region or item to the total power consumption and its variance in the institute- The authors discussed their influence on the total power consumption and its seasonal undulntion.
