Supply Potential and Annual Availability of Timber and Forest Biomass Resources for Energy in Japan

This study calculated incomes and expenditures such as silvicultural and harvesting as well as stumpage prices on Japanese cedar, cypress, pine, and larch forests using the silvicultural prescriptions set based on the regional forest plans and operation systems set based on topographic conditions such as slope angles and height differences with GIS. Then, this study estimated the availability of unused materials for woody biomass power generation plants under operation with FIT at the end of June 2020 as the supply potential from the profitable subcompartments. Considering the subsidy rate of 100% to secure the reforestations, the availabilities met the demands in Japan as a whole.
