Study on the Economic Performance of New Energy Projects in the Western Region of China taking into account of Environmental Benefits
With the proposal of"Carbon Peaking and Carbon Neutrality"goals and the introduction of the"1+N"policy system,China's new energy has developed rapidly,and the economical efficiency of wind power and photovoltaic projects have attracted public attention.Based on the theory of LCOE and IRR,taking five provinces in the western region as examples,the impact of technological progress,market scale expansion,participation in environmental transactions,etc.on project economic performance is analyzed,and cost space for energy storage configuration of the project under different circumstances are studied.The results show that increasing the power generation of wind power and photovoltaic projects and reducing unit construction costs can effectively improve project economical performance;vari-ous taxes and fees account for a large proportion of the tax-included kWh cost of electricity,and tax preferential policies can reduce costs and increase project benefits;carbon emission quotas and green power certificate trading can provide economic incentives for the develop-ment and construction of wind power and photovoltaic projects.CCER trading can increase kWh income by0.066 yuan/kWh;green cer-tificate trading can increase kWh income by0.05 yuan/kWh;the configuration of energy storage system in wind power and photovoltaic projects will significantly impact economic performance of the project.However,participating in environmental transactions can reduce the impact of energy storage configuration on project economical performance.
