根据部分水电站的预可研报告经济评价篇章的分析,设计院在计算经济评价中一般采用电网燃煤标杆电价进行价格对比计算分析。基于此,结合华中东4省电网燃煤火电标杆电价及华中东四省投运水电站上网电价进行统计、计算及对比分析,提出在水电站投资前期的水电站经济评价计算中以该地区平均水电上网电价代替现行电网燃煤火电标杆电价的设想,用以计算水电站投产后的电站资本收益指标。
According to the analysis of the economic evaluation chapters of pre-feasibility study reports of some hydropower stations, the design institute generally uses the coal-fired benchmark electricity price of grid to calculate and analyze the price in the calculation of economic evaluation. Based on this, combining with the statistics of the coal-fired thermal power tariffs in the four central eastern provinces and the grid-connected electricity prices in the four eastern provinces of eastern central China, the author puts forward that in calculating the hydropower station’s economic evaluation of hydropower stations in the pre-investment period, Instead of the existing power station coal-fired thermal power benchmark scenario, used to calculate the hydropower station after the power station capital gains indicators.
