ABSTRACT Electricity from renewable energy sources requires support to correct the negative externality of electricity generation based on fossil fuels as well as the positive externality of technology innovation effects of renewable energy technologies. However, poorly designed market regulations can lead to windfall profit for the renewable energy sector, increasing policy costs. In addition, those who benefit from such regulations may actively seek rents. Therefore, any regulatory intervention should be designed to reduce rents and rent-seeking behavior. This study investigates the rent generated through Renewable Portfolio Standard(RPS) and examines how it can be reduced through effective policy designs by focusing on the banding system of RPS in Korea. Multipliers in the banding system are examined and compared to those of Feed-in Tariff(FIT). This study concludes by summarizing its policy implication to improve the effectiveness of the banding system of RPS.
