西电东送输电价格弹性空间研究

Research on the Elastic Space of Transmission Price of West-to-East Power Transmission Project

[目的]电改背景下,跨省区专项工程的输电价格定价机制得以明确,在降低一般工商业电价的整体要求下,南方电网西电东送工程输电价格于2018-2019年经历了两次下调。厘清西电东送输电工程价格弹性空间,成为政府和输电公司关注的焦点。[方法]根据基于国内外跨区输电价格的定价经验,采用资产分摊,经营期电价,准许成本+收益等多种方法对西电东送输电价格的成本电价,核算电价和发文电价进行了测算对比。[结果]通过输电价格的研究测算,厘清了南方电网西电东送输电价格定价机制及弹性空间。[结论]基于实际的工程实证分析,证明测算方法合理有效,可为政府合理制定输电价以及输电公司投资决策提供依据。

[Introduction]Under the background of electric reform,the pricing mechanism of transmission price for special projects across provinces has been clarified.Under the overall requirement of lowering the general industrial and commercial electricity price in the country,the transmission price of Power Transmission from West to East Project of China Southern Power Grid Company Limited experienced two downward adjustments in 2018-2019.Clarifying the price flexibility space of the Power Transmission from West to East Project has become the focus of attention of the government and transmission companies.[Method]Based on the pricing experience of domestic and international transregional transmission prices,this paper combines the asset allocation method,the operating period electricity price method,the permitted cost+income and other methods,measuring and comparing the cost of electricity,the accounting price of the pricing plan and the government's issued electricity price of the Power Transmission Project from West to East.[Results]Through the research and calculation of transmission price,the pricing mechanism and flexible space of the Power Transmission Project from West to East has been fully understood.[Conclusion]Based on the actual engineering empirical analysis,it is proved that the calculation method is reasonable and effective,which can provide a basis for the government to reasonably formulate the transmission price and the investment decision of the transmission company.
