                            The promotion of electric energy production from solid biomass by the  Austrian government has lead to a boom in the construction of new  combined heat and power plants. The current total demand for wood chips  in the research area for energy purposes is 70 400 m3 of  loose volume chips per year. The expected increase in demand due to  these new plants is more than 4 times greater than current demand: up to  302 700 m3 of loose volume per year. Even if the energy wood  feedstock potential is satisfactory, the design of the supply chain is  still unresolved. The aim of this study is to give decision-makers a  base for further development. To accomplish this, we designed and tested  four different supply scenarios: one for 9 plants and one for 16  plants. The scenarios were developed using a combination of geographic  information systems (GIS) and linear programming methods. The results  indicate that direct transport of solid fuel wood as round wood and  chipping at the plant is the cheapest supply system with a resulting  cost of 5.6–6.6 EUR/m3 loose. Using harvesting residues can  only be recommended for large plants because of poor fuel quality. In  this case, residues would be chipped at or near the landing, piled and  transported via self-loading trucks at a cost between 8.4 and 9.1 EUR/m3 loose. In order to meet increasing demand and to ensure a continuous  supply, especially during the winter and spring seasons it is necessary  to optimize the supply chain by including storage terminals. However,  using terminals and increased demand both lead to higher logistical  costs. For example, if the total volume is handled via terminals, the  average supply costs including storage will increase by 26%. Higher  demand increases the costs by 24%.
