风电项目投资及其运行的经济性分析

The economic analysis on the investment and operation of the wind power project

风电项目投资的经济性,主要体现在成本与价格的对比关系上;风电项目运行的经济性,体现在风电替代火电而产生的成本(收益)变化上。通过建立相关成本分析模型发现,在目前风电设备价格较高而风电价格偏低的情况下,风电项目投资的经济性并不明显,但从长期来看,风电投资成本下降进而使其经济性改善的空间却很大。由于节能和减排的贡献,风电项目运行的经济性要明显优于风电投资,并且越是在发展初期就越明显。建议通过以价格补贴等方式,将风电项目运行的经济性转化为投资收益,推动风电产业的健康成长。

The economy of investment on the wind power project lies mainly with the comparative relation between the cost and the price, but the economy of the operation on the wind power project is manifested in the change of cost（benefit） caused by the fact that the wind power substitutes thermal power.After establishing the corresponding cost analyzing model, we discover that the e-conomy of investment on wind power project is not obvious at present due to the high price of wind power equipments and the low price of wind power.But in the long term, the cost of investment on wind power project will reduce, so its economy will be improved a lot.The economy of the opera-tion on the wind power project is superior to the investment, owing to its contribution to energy saving ＆ emission reduction.And it will be more evident in the initial development period.We suggest that, by the means of price subsidy, to transform the economy of the operation on wind power project into the benefits of the investment on wind power project is helpful for promoting the healthy growth of the wind industry.
