ENThe main problem of the paper is that today inevitably emerges necessity provide alternative energy, who not undermine environment and save terminative world resources. Biomass clusters can help make it, but simultaneously they promote at business competitiveness growth. The aim of the paper – create a biomass cluster model. In scientific literature biomass clusters working and their influence to business competitiveness is comparatively little investigate. The authors accomplished research results show, that biomass clusters interact with other clusters can compete with them. In energetic sector clusterization processes operate through usable fuel type, apply technologies for him, and later cluster seeks energy users. Paper authors develop clusterization influence to competitiveness methodology suggest clusterization influence analyse separate case. Then upstate opportunity creates cluster at the best of times. Regions compute invoke the regional concentration index and biomass strategic potential. Authors accomplished calculation and researches indicated, that cluster members get direct (marginal profit) and indirect (synergies and multiplication effects) benefit. Theoretical generalizations doing investigate Lithuanian clusters and analyse analogous other scientific researches. Using authors proposes a suggestion, on biomass clusters incoming companies can increase their competitiveness not only energy production sector.
