Study On The Coal-electricity Integration Model And Economic Benefit Of Company G

In response to the long-standing contradiction between coal and electricity,based on the analysis of the characteristics of energy structure in China and the research status of coal power integration at home and abroad,this paper defines the concept of coal-electricity integration,and comb the history and characteristics of coal-electricity integration in China.Studied on the integrated operation mode of G company in coal and electricity,the economic benefit calculation model of coal power integration project is constructed.Combined with the actual situation of HM coal power integration project,which is belong to G company,an empirical analysis is made for the economic benefit model.The main research contents are as follows:1.Combing the three operation modes of G company's coal-electricity integration,First,Coal mines and power plants are different production departments under the same corporate coal power company;Second,Coal mine and power plant are independent legal persons,but belong to the same coal power company;Third,Coal mines and power are integrated through mutual equity or contractual joint operation;and the advantages and disadvantages of the three operating models are analyzed and compared.It point out four complementary modes of G company's integrated operation of coal and power,namely,coal-electricity complementation,water-steam complementation,coal-ash complementation and guarantee sharing.2.The economic benefit calculation model of coal power integration project is constructed.The total economic benefits of the coal-electricity integration project of company G include four parts: coal-electricity complementary economic benefits,water-steam complementary economic benefits,coal-ash complementary economic benefits and guarantee sharing economic benefits.HM Coal and Electricity Company,which is a subsidiary of G Company,is selected to conduct empirical research,the coal-electricity integration operation can achieve cost saving,increase economic benefits of about 37.0166 million yuan,and save fixed asset investment of 12.55 million yuan.Among them,the complementary economic benefit of coal-electricity is9.4326 million yuan;the complementary economic benefit of water-vapor is 12.744 million yuan;the complementary economic benefit of coal-ash is 9.84 million yuan;and the guaranteed sharing economic benefit is 5 million yuan.At the same time,it puts forward proposals for optimization and improvement of integrated operations tofurther enhance the comprehensive benefits of coal-electricity integration projects.3.Study on the integrated production and operation strategy of HM Coal and Electricity Company,it can calculate the market coal price warning value.Based on changes in coal market prices,the coal-electricity integration projects should adjust coal purchase-sales and power generation strategies to improve the company's overall economic benefits.
