Long-term electric system expansion planning in Korea

The optimal mix of electric power capacity in Korea up to year 2001 is carried out by means of the WASP model using the scenario approach. In addition, sensitivity analysis in terms of fuel cost and capacity factor is also carried out. The scenario approach shows that the increment of nuclear capacity during the period of 1988-2001 is expected to be 6,650 MW, representing 32% of the total capacity increment. On the other hand, the capacity addition of coal power plants during the same period is to be 14,000 MW, representing 68% of the total capacity increment. The paper also gives some insight about Korea's economic planning and the past and future trends of energy/electricity consumption, and the current government policies to cope with demand in increases under a situation of limited endogenous resources.
