8차 전력수급기본계획에 따른 신재생에너지 발전비용과 경제적 파급효과 분석

[Purpose] Renewable energy－related policies are major effort to solve the climate change problem. There is a great interest in the economic effects and costs. Since renewable energy has not yet secured a competitive edge compared to existing power generation sources, interest in future cost changes is also enormous. Therefore, this study estimated future economic ripple effects and costs based on recently announced renewable energy policy. [Methodology] In order to estimate the future economic ripple effect, we used the 2014 data to calculate the production inducement effect in the renewable energy sector through input－output analysis. The cost of renewable energy generation is calculated based on levelized cost of energy. [Findings] From 2020 to 2030, the production inducement effect is about KRW 100 trillion for other industries, which is the total generation cost of KRW 5.25 trillion and cost of renewable energy policy is about 84.5 trillion won, confirming that the renewable energy sector is of great economic value. In terms of cost by power generation source, installation cost is the major determinant for solar and wind power and fuel cost is the major determinant for biomass and fuel cell. [Policy Implications] This study shows that the current policy for renewable energy supply is economically valuable. And the technological innovation and ecosystem creation efforts should be required to decrease installation cost. In addition, this study suggests that there is a need for interest of accounting academia in the cost and economic analysis of the power industry.
