Abstract

Currently, the RPS(Renewable Portfolio Standard) is the policy which supplies new and renewable energy. Power generation companies with large capacity should produce renewable energy or secure through the purchase of REC (Renewable Energy Certificates) as mandatory. The government has revised the REC weight several times, which weights each energy source by evaluating the economic and social value of renewable energy sources, and revised the mandatory supply ratio to gradually increase. This study helps to find the impact of policies on related industries. In this study, time-series analysis and regression analysis on the capacity of PV(Photovoltaics) facilities as a dependent variable were performed to analyze the effect of the revision of the REC weight for photovoltaic power generation and the amount of mandatory supply for renewable energy. As a result, it was statistically assessed that the revision of the REC weight and the increase in the mandatory supply has a significant effect on the increase in the amount of PV facilities.

현재 국내 신재생에너지 보급 정책은 RPS(Renewable Portfolio Standard; 공급의무화제도)이다. 대용량 발전사업자는 신재생 의무공급량을 직접 생산하거나 REC(Renewable Energy Certificates; 공급인증서) 구매를 통해서 확보한다. 정부는 신재생 에너지원의 경제적, 사회적 가치를 평가하여 각 에너지원에 가중치를 매기는 REC 가중치를 여러 차례 개정했으며 의무공급 비율도 점차 증가하도록 개정했다. 본 연구는 정부의 정책이 관련 산업에 미치는 영향을 확인하는 데 도움이 된다. 태양광발전에 관한 REC 가중치 개정과 신재생 의무공급량이 태양광 설비량에 미치는 영향을 분석하기 위해 태양광 설비량을 종속변수로 시계열 분석과 의무공급량에 대한 회귀분석을 수행하였다. 결과적으로 REC 가중치 개정과 의무공급량 증가는 태양광 설비량 증가에 유의미한 영향을 미친다는 것을 확인하였다.
