Abstract:The national energy policy of Poland supports the maintaining of coal as the main fuel in electricity generation in the foreseeable future, with the simultaneous increase in biomass use, especially from perennial energy crops, viewed as the source of 95% of biomass fuel. The present article analyzes the logistics of biomass supply using a transport cost linear programming minimization model to balance the supply with the demand. The supply was determined from a potential biomass production assessment. The demand was predicted according to two scenarios (for 2008 and 2020) of biomass demand by the 20 largest power stations in Poland. The analysis showed the radius of supply around the power stations to be uneven, depending on the demand and station location. Two logistic features were identified: border proximity and clustering. Power stations situated by the country border have supply areas extended inland. Proximate power stations tend to form clusters. The comparison of the radius of supply between the two scenarios indicates its uneven growth by 39-385% depending on a power station. In the 2020 scenario the radius of supply varies from 30 to 200 km. The upper part of this range is the effect of competition for supply area and is indicative of possible future problems with biomass supply and transport. Reduction of transport costs could be achieved by the introduction of individual demand quota or/and the introduction of other means of transport (rail, ship).
