Four modes of coal and electricity integration development

The four models of energy and coal companies that integrate development of coal and electricity are developing coal and power projects at the same time. The company will set itself as an integrated energy company, attach equal importance to the development of coal and electricity, and use coal and electricity as a development strategy. The coal-electricity integration representative companies are Shenhua Group and National Development and Investment Corporation. Shenhua Group's raw coal production in 2010 reached 357 million tons, while the total installed capacity of the commissioned power plants reached 33.947 million KW. In the period of heavy coal surplus in the late 1990s, Shenhua Group avoided the difficulties of coal sales faced by many coal companies through the development of power projects and successfully passed the difficult period of the coal industry. The National Development and Investment Corporation has developed a coal and electricity integration business strategy and achieved remarkable results. In 2010, the National Development and Investment Corporation's installed capacity for electric power reached 29.397 million KW, and its annual coal production capacity reached 25.98 million tons.

Coal companies set up power stations. Coal companies will maximize their economic efficiency by extending the coal industry chain and comprehensive utilization of resources to develop power projects. Since the late 1990s, coal companies have attempted to develop large-scale electric power projects. The typical example is the development of a 135MW power project by Datun Coal and Power Company. However, due to the influence of the recipient system and funding issues, coal companies have been slow to develop power projects, and power projects have been limited to coal gangue and coal slime power plants. Since 2002, with the reform of the power system and the improvement of the efficiency of coal companies, the activities of coal companies to build large-scale power plants have begun to flourish. At present, most large-scale coal enterprises have already built large and medium-sized integrated utilization power plants. For example, the Yangquan Coal Group has constructed a 3×135MW comprehensive utilization power station, and Xishan Coal and Electricity Group is building on the basis of putting into operation 2×300MW coal-fired power plants. 2 × 600MW coal-fired power station. At the same time, with the construction of large-scale coal bases, large-scale coal companies are actively building large-scale coal-fired power stations in pits to achieve integrated operation of coal and electricity.

Power companies set up coal mines. Power companies provide reliable coal supplies for their power plants through mergers and development of coal mines. In recent years, due to the rapid increase in coal prices, the profits of the power industry have been continuously reduced. In the first half of 2008, the operating profit of the entire power industry fell sharply. Four major power companies in the top five power companies suffered losses. The rise in the price of coal has prompted power companies to set up coal mines. Electric power enterprises can enhance the market competitiveness of power plants. In the first half of 2008, 10% of the subsidiaries of the five major power companies maintained profitability, mainly due to the adoption of a coal-fired electricity pooling model.

Coal and power companies jointly operate coal power projects. With capital as a link, coal and power companies have used their respective advantages to establish joint ventures and jointly operate coal mines and power projects. For example, Huainan Mining Group has successively established a coal and electricity integration cooperation project company with Zhejiang Energy Group and Shanghai Electric Power Company. Its joint venture company with Zhejiang Provincial Energy Group Co., Ltd. simultaneously constructed a mine with an annual output of 6 million tons of coal and a power plant with an installed capacity of 4×600,000 KW, of which the power generated by the power plant was all supplied to Zhejiang Province. The First Mine and First Plant (Dingji Mine and Tianji Power Plant) established by Huaihu Coal and Power Company, a joint venture with Shanghai Electric Power Company, is the first coal-fired electricity integration enterprise group in the country to operate coal-fired electricity to reduce the amount of coal used for transmission. The middle of the transaction. In recent years, this kind of coal-electricity joint venture model has developed rapidly. The five major power companies have jointly established large-scale pit power station projects with large-scale coal companies such as China Coal Energy Corporation, Datong Coal Mining Group Corporation and Kaiyuan Mining Group.
