This study analyzed the status and policies of renewable energy generation in Korea and outlined new policies to be introduced. The 2 main policy measures, FIT(Feed in Tariff) and RPS(Renewable energy Portfolio Standard), were compared and analyzed through causal loop diagrams. Also, we developed causal loop diagrams considering the newly introduced policies and analyzed the expected policy effects.
Finally, we suggested policy implications for increasing renewable energy supply.
As a result of analysis of renewable energy policies through causal loop diagrams, it was found that RPS system had limitations in expanding the supply of renewable energy. In addition, the government's long-term fixed price bidding system is also difficult to escape from the constraints of the RPS system. FIT system for small scale power plant is expected to complement the shortcomings of the RPS system.
Environment and safety-conscious power supply systems can contribute to the expansion of renewable energy supply by affecting the supply of existing power generation sources.
