垃圾填埋气回收发电的经济性和激励政策研究

Study on the Profitability of Landfill Gas Recovery and Power Generation and Relative Incentive Policies

本文研究了垃圾填埋气回收发电项目的经济性和政府激励政策的影响。这类项目的经济性,受税收政策、项目寿命期和上网电价影响,还受初始投资、运行费用和销售收入的影响。政府可以通过优惠税收政策和给予优惠上网电价两种方式影响项目的经济性。在现有税收政策下,合理地确定项目的上网电价,能较好地兼顾项目和政府的收益。

The paper studies the profitability of the project of landfill gas recovery and power generation, and impacts of the government inspiring policies on the profitability of the project. The profitability of the project is influenced by preferential tax, life span of the project and supply price to grid, also by initial investment, run cost and income from sales. The government may influence the profitability of the project by two kinds of policies, which are preferential tax and preferential supply price to grid. On the other hand, making reasonable supply price to grid could give attention to the benefits of project and government on existing tax polices.
