According to the analysis, it is found that the profit from supply chain cooperation between coal and power enterprises is more than that of non- cooperation. The cooperation is validated to be beneficial for both units; however, the profit is mainly taken by the power enterprise. Thus, it is necessary to set up the incentive mechanism to distribute cooperation value between coal and power enterprises to promote their continual cooperation.展开更多

It also presents some policy proposals to relieve the contradiction betweencoal and power, including to intensify macroscopic regulation between industries and regions, solve theproblem of power coal transportation and reduction or exemption of tax on coal industry and circulationlinks, through secondary distribution to regulate profit difference among industries.展开更多

This results in a substantial decline of profits and more operating difficulties in the downstream electric enterprises. The listed companies in both coal supply and power industries have quality assets and are the representatives of these industries. Through the analysis of the financial and operational status of the listed coal supply and power companies since 2007, the reasons for the business development difficulties in the electric power industry were discussed. Recommendations were provided including improving the coal pricing system, increasing the degree of business integration of the coal and electric power industries, and adjusting energy structure.展开更多

Different types of crop residue are collected from farmers depending on the geography and crop pattern for instance, in north India rice straw and cotton stalks are collected while in central India soya husk and sugarcane tops are collected. Baling and transporting straw from the field, though appear to be an option for safe disposal, will be feasible only when alternate, effective and economically viable usage methods are identified and facilities and infrastructure for ex-situ management methods are created. One immediate short term use of the residue is to replace 5% - 7% of the 670 million tonnes of coal India currently consumes to generate power. The farmers will benefit from the sale of their excess crop residue. The scheme will reduce pollution due to residue burning practices. Replacing coal will cut the GHG emissions. The challenge is to mobilize the crop residue collection and timely delivery to power plants. The data and calculations in this monogram show that it is economical for the farmer to remove the crop residue from the field quickly by using modern balers, to pelletize the biomass in small-scale distributed pellet plants, to store pellets in the modern steel bins and finally to deliver the pellets to coal plants by using rail transport. The delivered cost is estimated at around Rp 6.78/kg. The Government of India encourages the power plants to pay at least Rp 10/kg for the delivered biomass in the form of pellets. The current monogram analyzes the organization of an efficient supply chain in the State of Haryana India to ensure a sustainable modern enterprise.展开更多
