Biomass supply costs are costs of the biomass available at power
plant storage—PPS. PPS contains the biomass for about 2 weeks of
power plant consumption and is supplied from primary storages,located in the vicinities of biomass sources. Total supply costs consist
of the price of biomass purchase at the primary storage (paid to
farmers), costs of storing biomass at the primary storage (including
handling), and transport costs between the primary storage and PPS
(including unloading at PPS). Agricultural biomass is considered in
the form of a big round or rectangular bales, and forest biomass in
the form of wood chips. The characteristics of four considered
biomass types are presented in Table 1.
