일본 RPS법의 법정책적 시사점

Abstract

It is recognized that PRS and FIT are two main policy instruments to promote renewable energy. The Korean Government announced in 2008 that renewable energy promotion scheme will be changed to RPS from current FIT system in 2012. On the one hand, Japan has executed PRS Act since 2004, but the effect isn’t rated so high. Although the public electricity suppliers fully cover the customer targets as of the end of 2008, the customer targets are too low and the incentive for the participating businesses is insufficient and the principle of the market which is the competition promotion among the businesses is not fully used in reality. If it is impossible to withdraw the transition to RPS System, we’ll have to take the Japanese case where they have some problems after the introduction of RPS as a lesson and prepare a plan to transit into the induction of the promotion of competition within the development technology of the same renewable energy; that is, we will (1) set up the mandatory introduction quantity, (2) execute a separate supporting policy by separating the renewable energy of equipment type like solar lighting or wind power etc. from RPS System, or (3) segmentalize or differentialize as much mandatory RPS quantity by the technologyㆍscale as possible. In addition, FIT and RPS have their respective merits, and there are some differences in the results of the market of the renewable energy industry which two systems will bring about in future. Moreover, considering that many stakeholders come out as the energy-related system is executed and changed, we make sure that when we supplement the demerits and take the merits by applying two systems in parallel for a certain period, we shall be able to enhance the likelihood of success of the renewable energy industry.
