The optimal woodchip production system was developed and the production cost of a forest woodchip fuel was calculated for utilizing the pitch pine, which covers around 480,000ha nationwide. the marginal price of the woodchip fuel considering the factor of supply price, electricity and heat selling price as well as capacity factor were suggested and the economic sensitivity analysis was conducted for various scenario. The most important variable which determine economic feasibility was a fuel cost for the power generation facility. If the electricity price is higher than the current SMP(System Marginal Price) or the capacity factor is higher than 80%, there fully is a benefit to consume the woodchip fuels produced in the suggested production system in this study. In addition, the additional benefit becomes more obvious when considering REC(Renewable Energy Certificate) and CDM(Clean Development Mechanism). Therefore, it is strongly suggested for domestic power generation sector to utilize the forest biomass fuel to achieve the obligatory target of RPS.
