LCOE与项目投资IRR指标对比研究——基于可再生能源项目

Comparative Study of LCOE and Project IRR About Renewable Energy Project

针对平准化度电成本的本质,修正适用于国内项目的平准化度电成本计算模型,并对比研究与传统财务评价指标的基础数据,通过理论分析和实例验证平准化度电成本与项目投资内部收益率内在联系,当LCOE计算的折现率等于项目投资内部收益率时,对应电价等于LCOE值。在项目投资决策时,只要确定项目加权平均资本成本,即LCOE折现率,作为项目投资内部收益率,使用传统经济评价模型测算对应的平准化度电成本,即成本电价。

Aiming at the essence of Levelized Cost of Electricity,the calculation model of the Levelized Cost of Electricity applicable to domestic projects was modified,and the basic data of the traditional financial evaluation index was compared with Levelized Cost of Electricity.and verifying the internal relationship between the Levelized Cost of Electricity and the internal rate of return of project investment through theoretical analysis and practical examples.When the discount rate calculated by LCOE is equal to the internal rate of return of project investment,the corresponding electricity price is equal to LCOE value.In project investment decision-making,as long as the weighted average cost of capital(LCOE discount rate)is determined as the internal rate of return of project investment,the traditional economic evaluation model is used to calculate the corresponding levelized electricity cost,namely cost electricity price.
