This paper presents the results of an optimisation algorithm for biogas use. There is considered the case of the big farms. Generated biogas from manure is an important energy resource. The goal of the research is to estimate how biogas can cover the energy demand of the farms. Special software has been developed for managing the energy, environmental and economy balances. The best approach is to use biogas for producing heat and power. One can assume different heating schedules and electricity needs. Energy consumption for hog, poultry, beef and dairy farms can be simulated. The potential of the generated biogas is estimated using specific indicators. The software is able to find the optimal size of the biogas engine and boiler for different cases. The energy production is compared with the needs of the farm. As a result, there are presented financial analysis of valorisation projects for different types of animal farm.
