Abstract

Integrated gasification combined cycle (IGCC) power plants not only emit less greenhouse gases and air pollutants than conventional coal-fired power plants, but also use low-price, low-quality, and internationally easily procurable coal. Thus we can benefit from safeguarding energy security through building the IGCC power plant. This paper attempts to value the benefits of energy security enhanced by IGCC power plant. To this end, we report here the results from a contingent valuation survey of randomly selected 600 households. A combination of a double-bounded model and a spike model is applied for the purpose of increasing statistical efficiency and dealing with zero(0) willingness to pay data, respectively. The results show that the respondents are additionally willing to pay 6.05 won for 1kWh of electricity generated from IGCC power plant. In other words, the benefits from safeguarding energy security through building the IGCC power plant are 6.05 won per kWh. Given that the expected amount of generation from the Taean IGCC power plant that is scheduled to be built in late 2015 is 2.27 TWh per year, the benefits are estimated to be 13.74 billion won per year.

석탄가스화 복합발전소는 기존 석탄화력 발전소에 비해 온실가스 및 대기오염물질을 적게 배출할 뿐만 아니라 국제적으로 쉽게 확보할 수 있는 저렴한 저품위 석탄을 사용할 수 있어서 연료를 안정적으로 공급받을 수 있다. 이에 본 논문에서는 석탄가스화 복합발전 건설의 에너지안보 확보편익을 추정하고자 한다. 이를 위해 무작위로 추출된 전국 600가구를 대상으로 설문조사를 수행한 후 얻은 자료에 조건부 가치측정법을 적용하여 분석한 결과를 제시한다. 통계적 효율성의 확보를 위해 이중경계 모형을 적용하며 영(0)의 응답자료를 적절하게 다루기 위해 스파이크 모형을 적용한다. 분석결과 석탄가스화 복합발전소로부터 생산되는 전력 1kWh에 대해 응답자들은 평균적으로 6.05원의 추가적인 지불의사액을 가졌다. 즉 석탄가스화 복합발전소로부터 생산되는 전력에 대한 에너지안보 확보편익은 6.05원/kWh이다. 올해 완공되는 태안 석탄가스화 복합발전소의 예상 연간 발전량은 2.27TWh이므로 에너지안보 확보편익은 연간 13,740백만원으로 추정된다.
