Optimal location and size for a biomass plant: application of a GIS methodology to the “Capitanata” district

The aim of this work is to outline a methodological procedure to assess the most advantageous logistic use of agricultural residues (such as straws) in order to supply a biomass energy plant using the economic criterion of the maximization of the NPV (Net Present Value). A GIS (Geographic Information System) neighborhood statistics procedure was applied in order to locate the biomass plant. Results showed that the optimal radius of the supply basin was not related to (but independent of) both total amount and spatial distribution of biomass resources within the basin; ifferently, biomass availability strongly affected the size of the plant and the corresponding NPV. Therefore, the optimal plant location was at the center of the geographical area constantly characterized by the highest biomass density at different orders of scale.
