煤电价格联动机制对发电成本-利润影响分析

电煤价格变动对发电成本和利润影响极为显著。国家发展和改革委员会为此制定了煤电联动政策。实施煤电联动机制对发电企业经济效益影响的定量分析是发电企业极为关注的问题。从经济核算和盈亏平衡的角度研究煤电价格联动机制对火电企业成本-利润的影响,进而建立影响大小的计算模型。通过典型实例计算,得出如下结论:如果不实施煤电价格联动机制,煤价每上升1%,发电利润将下降超过3%;而实施煤电价格联动机制(消化比例为30%),则煤价每上升1%,发电利润将下降约0.95%。

Analysis for influence of coal and electricity price linkage mechanism on electricity generation cost-profit

The impact of coal price fluctuation on electricity generation cost-profit is extremely remarkable. The national development and reform commission constituted the policy of coal-electricity price linkage. The quantitative analysis of the influence of implementing coal-electricity price linkage mechanism on economic benefit of power plant is concerned greatly by power plant. From two angles of both economic accounting and balance of profit and loss, the influence of coal-electricity price linkage mechanism on the cost-profit of power plant was researched, and the calculation models about this influence were given further. Through calculation of typical example, the conclusions show that when coal price rises 1%, the electricity generation profit will reduce at least 3% if coal-electricity price linkage mechanism is not implemented, while the electricity generation profit will reduce 0.95% if this mechanism is implemented.
