Renewable energy sources will play in the years to come a central role in moving the world onto a more secure, reliable and sustainable energy path. In this paper the case of an Italian power plant fed from biomass (de-oiled pomace and waste wood) is discussed for an agricultural district. The optimal operating conditions are addressed by setting up an information model for the improvement of accuracy of estimation of the potential of biomass from the sustainability perspective. Criticalities of data consistency and coherence are highlighted too as a function of the systemic problem introduced by the several sources within the agricultural district.
