The project to utilize kenaf as thermal power plant fuel has a positive effect on the unused energy utilization, greenhouse gas reduction, and farmincome. However, it is analyzed that it is difficult to secure economical efficiency because the fuel cost of kenaf is higher than that of power by thermalpower plant and Renewable Energy Certification (REC). The project of power generation using kenaf is meet the government’s major policies, whilegovernment support is essential for securing economical efficiency. As a result of the sensitivity analysis on the ratio of the government subsidies, tosecure economical efficiency, the power generation prices using kenaf through the direct financial support of the government indicate that 47% and 76%of kenaf fuel cost are supported by government in case of the Saemangeum reclamation and Gangneung-si, respectively. In the case of the governmentindirect policy support, if kenaf is included as a renewable energy source of Renewable Energy Portfolio Standard and REC is granted, the economicefficiency of Saemangeum reclamation and Gangneung-si is obtained when REC secured at 1.05 or more and 2.43 or more, respectively. The results of this study are meaningful in that the direct and indirect effects of the government on the development of the herbaceous energy crop,kenaf, were evaluated economically. These results are to suggest the need for demonstration study, but economics analyze and evaluate are necessarybased on operational data through the demonstration phase in the future.
Abstract
The project to utilize kenaf as thermal power plant fuel has a positive effect on the unused energy utilization, greenhouse gas reduction, and farmincome.

The project of power generation using kenaf is meet the government’s major policies, whilegovernment support is essential for securing economical efficiency.
