This paper presents results of the study of the whole chain from biomass resources, creation of business opportunities and contribution to the regional development in Banska Bystrica region, up to the technical solutions for boilers reconstruction. The first part of the study was focused on identification of biomass resources for energy use from forestry, wood processing industry and agriculture with the use of GIS tools. Ecological, economical and operational factors limiting utilization of potential biomass resources were identified (protected forests, forests in the 5th category of IUCN nature protecton, sensitive and poor soils, regions with slopes over 50%), factored into calculatons and inaccessible biomass was excluded from further calculatons. The precise analysis of the logistics of the wood supply was prepared. The total forest land area of the Banská Bystrica Region is 453,000 ha. When the limiting criteria referring to the forests categories, their nature protection and site fertility were applied, the forest area for calculation of the total wood resource and energy biomass has decreased to 258.3 ths. ha (57.0%) and the growing stock of biomass to 1,245.1 mil. m3. Application of other limiting factors of technical nature (especially slope inclination), resulted in the potential volume of biomass for energy generation of 302.4 mil. m3, what equals to 18.3% of the planned annual cut and 24.3% of the region´s total available biomass resources.
