Abstract
A mixed integer programming model was developed to estimate the delivered cost of woody biomass under different woody biomass handling systems. The objective of the model was to optimize a woody biomass based biofuel facility’s location while minimizing the total annual delivered cost of woody biomass under resource and operational constraints. The model was applied in the state of West Virginia. Results showed that the optimal location for a 900 tonnes of dry woody biomass plant would be at Addison or Grantsville in West Virginia, depending on the system used. For that base-case scenario, the average delivered cost varied from $2.30/GJ to $3.02/GJ among the systems. Sensitivity analysis was performed under different scenarios, including biomass availability and purchase–stumpage price, demand, extraction distance, and fuel pricing. The delivered cost was mostly affected by woody biomass demand at the plant. Skidding distance had the least impact on the delivered cost. The results would be useful in facilitating the research and economic development of woody biomass utilization for bioenergy in the region.
