Predicting the Supply and Demand Situation of Coal Power in Thermal Power Enterprises in Hunan Province and Main Measures

Since the beginning of this year, faced with the severe situation of rapid growth in electricity demand, delayed water and electricity supply, and increased dependence on thermal power, relevant departments in Hunan Province have stepped up production scheduling management, optimized the adjustment of coal operation, and supported the steady and rapid industrial economy in the province. development of. It is expected that during the period of peak winter, the province's coal supply may still have a certain gap, and the task of coal adjustment and power conservation is still very arduous.

First, the supply and demand situation of thermal coal in the winter months From January to September, due to severely affected by the water, the demand for thermal coal in Hunan Province increased significantly. The province's power plants organized 11.75 million tons of coal from the province, an increase of 20.4% year-on-year; 15.71 million tons were imported, an increase of 16.1%. The cumulative consumption of coal was 27.75 million tons, an increase of 32.3% over the same period of last year, and the overall supply and demand of coal remained tightly balanced.

This winter, precipitation in Hunan Province is still not optimistic. According to meteorological department forecasts, the total precipitation in Hunan Province is about 1070mm, which is 25% to 30% less than normal years. At present, the water level of the major reservoirs in the province is very low, which will seriously affect the capacity of hydropower generation during the later period, especially during peak winter. At the same time, after the country implemented new standards for power transmission security, the contact line was reduced from the original 2.6 million kilowatts to 160 kilowatts, and the transmission of electricity into Hunan was significantly reduced. Comprehensive multi-factor analysis, it is expected that during the peak winter season, the province's coal consumption will be over 130,000 tons per day, and only 9 million tons of coal will be transferred to the coal normally every day. In the fourth quarter, the coal gap in the province will be more than 3 million tons.

II. Main work measures to ensure the smooth operation of thermal coal in winter In response to the complex and severe power coal supply and demand situation and the problems encountered in the operation of thermal coal during the winter peak season, relevant parties in Hunan Province will further intensify the efforts for factor protection and operation adjustment. To ensure the smooth and orderly operation of coal throughout the province.

The first is to continue to do a good job of coal conversion and electricity conservation. Continue to organize the province's power companies and key coal-producing counties and cities and towns, and actively carry out coal conversion and electricity protection work, and strict assessment, and strive to ease the tension in the province's power coal supply; organize power grid companies to actively fight for power supply in other provinces. At the same time, while consolidating existing coal procurement channels, it has actively opened up new coal sources in Shaanxi, Inner Mongolia, Yunnan, Gansu and other places, and strived to use the new transportation channels such as the Yangtze River transportation and sea transportation to expand the transportation channels.

The second is to strictly implement the orderly power supply and demand side management work in the province. Timely forecasting and early warning of power supply and demand balance in the province, and preparing an orderly power supply plan in advance for potential power supply shortages, so as to ensure “limited coverage” and prioritize the protection of household electricity consumption and electricity consumption for important users. Minimize the impact of power cuts on economic and social development and residents' lives. At the same time, it actively carried out demand-side management work, strengthened the management of power users, increased power-saving propaganda, and guided and promoted the use of electricity in society as a whole, and rational use of electricity, saving electricity.

The third is to actively promote energy-saving scheduling. Strengthen the disclosure of power grid dispatching information, scientifically and rationally arrange power generation methods, and give full play to the power generation capacity of high-efficiency and low-power consumption units. During the period of power shortage, it actively promoted the warning of coal power and carried out the work of “coal and power generation” to mobilize the enthusiasm of thermal power companies. Further optimize the operation mode of the power grid and small hydropower, do a good job in the operation, maintenance and optimization of dispatching of reactive power equipment, and strive to reduce the power consumption. By signing alternative power generation agreements, conducting power generation index transactions, and establishing trading operation platforms, energy saving dispatching and resource optimization can be achieved in various ways to achieve energy conservation and emission reductions.
