The evaluation of results of using biogas power plants
University of Novi Sad, Faculty of Agriculture

Abstract

As a rule biomass is not economic for transport and therefore is rarely a part of merchandise trade. Due to that reason, in this paper it was necessary to analyze the economic results of generation of power and heat energy from biomass that is used in the biogas power plants with the aim of spreading the energy to as many users as possible. Not only economic results of the use of biogas power plants are being evaluated but also the sensitivity of the yield value of the plant to the change of income, expenses and discount rate. The projected business results show that with the generation of power and heat energy using the wasted biomass positive financial results can be achieved. It is determined a high economic efficiency over 1,25 and the rentability is 5,28%. The yield value of the plant is much lower in comparison to the total investment. The analysis of sensitivity shows that income increase for 10% and simultaneous expense decrease for the same amount, as well as the decrease of discount rate for 1% will change the yield value of the biogas power plant, while the yield value would still remain lower than the made investment.

Keywords
