한국전력시장의 변동비가격제도에 관한 소고

Like advanced and developing countries having undertaken market-driven reform in the power industry, Korea began transforming the structure of its electricity industry from the public monopoly to market competition in 1997. As the first step of the restructuring plan, the division of generation was separated from the state-owned monopoly company(KEPCO) and the Korea Power Exchange(KPX) was formed as a market and system operator to govern the power pool and network system of the electricity industry. The pricing method chosen for use in the Korean power pool is the Cost Based Price(CBP) system, under which the price is determined by the KPX as the sum of the System Marginal Price(SMP) plus the predetermined Capacity Payment(CP). Therefore the price determined by the KPX is not real market price. This paper examines the issues whether the Constitutional Law, the Electricity Business Law or the Korean Competition Law admit the CBP system, which does not allow the electricity enterprisers' freedom to set the price of their own commodities.
