The sky was clear, autumn is getting stronger, when people wear thin coat, no longer open air conditioning, hot summer has gone. With the whole society electricity load began to gradually decline, power Yingfengduoxia tackling the perfect ending battle, painted in the end.

This sweltering summer. According to the data released by the China Meteorological Administration, the national average temperature in summer 2014 is higher than that in the whole year, and the electricity load in many areas of the country has been innovating. Under the "three high" conditions of high temperature, high load and high risk, the State Grid has withstood all aspects of severe test and challenge. The power grid is strong and the power supply is reliable. People do not feel the electricity pressure has passed through a comfortable summer.

Every summer is the peak of a protracted, thrilling crucial war.

This year before the peak of the summer, 1~4 month, the whole social electricity consumption increased by 5.2%, increasing speed by 0.3 percentage points compared with the same period of the previous year. The situation is more severe. The national Power Grid Corp operating area as an example, although the overall balance of power supply and demand balance, but the uneven distribution of local gap exists, especially Beijing Tang, South Hebei, Shandong power grid, the implementation of desulphurization coal-fired power unit capacity of 36 million 840 thousand kilowatts, the total maximum electricity shortfall of 14 million kilowatts, orderly supply of electricity has great pressure.

The facts have proved that the prediction is scientific and accurate. This year, the 4 regional power grids and 17 provincial power grids in North China, East China, central China and Northwest China have high load. The 8 provincial power grids in Shandong, Hebei, Hebei, South China, Tianjin, Jiangsu, Fujian, Henan and Shaanxi have tight supply and demand, and the largest power gap in the region is 4 million 570 thousand kilowatts. In July 22nd, the total daily power generation in China reached 17 billion 859 million kwh, and the power load (dispatching caliber) of the national grid reached 658 million kilowatts, the highest value in history.

This year the Yingfengduoxia work is facing new challenges. During the summer, the national Power Grid Corp to maximize cross transmission channel, cross transmission in North China, East China and central China the largest power reached 12 million 70 thousand kilowatts, 34 million 760 thousand kilowatts, 15 million 510 thousand kilowatts of power grid, all loaded, West to east channel, at all levels of power grid, contact surface, broken hub face long period and large load test. The main flood season, Xiangjiaba, Xiluodu, Kam and other large hydropower started production area of new hydropower installed capacity of 5 million 260 thousand kilowatts, while the thermal power generation capacity decreased, the power dispatching operation of contradictions, difficulties, how to ensure the safe operation of the electrical network, how to make clean energy "can be sent", is the key to this year the summer peak.
