Abstract: Paying attention to the influence of economic development level and energy sources distribution on the loading characteristics of power grid will help to adjust and formulate corresponding power consumption plans, reasonably schedule power generation, lower power generation cost and and ensure safe and reliable power supply. In this paper, the annual growth trend and monthly fluctuations of electric power demand in Beijing-Tianjin-Tangshan Power Grid from year 2005 to 2013 is investigated, and the load of typical days in summer and winter are analyzed. Furthermore, based on an analysis of the variation and adjustment of the country’s economic policy, the power demand and electric power consumption characteristics from year 2014 to 2016 are forecasted. The above information will provide a reference for electric energy consumption planning, demand side management and formulating policy on energy saving and emission reduction.

Key words: Beijing-Tianjin-Tangshan power grid, electric power load, load characteristics, electric power consumption structure
