The aim of this master's thesis is to evaluate the economic feasibility of implementing biogas plant on a selected farm for the production of electricity. This assessment was based on a laboratory experiment in which livestock manure from the farm was mixed in appropriate ratios to produce biogas. Both the quantity and composition of the biogas were measured. From these measurements, we calculated the potential annual methane yield on the farm. Subsequently, we developed three groups of scenarios. First group of scenarios represents current situation, in which there are 110 animals on the farm. Second group of scenarios represents increase of number of animals by 40 heads and the third group represents if the farm would also add food waste from local restaurant in biogas reactor. In scenario 1 the farm could produce 9.424 m3 methane annually. In second scenario 14.203 m3 and in third 17.123,5 m3 of methane yearly. For each scenario, we calculated revenues, costs, estimated the required investment, and computed various profitability indicators. Within each group of scenarios, we further considered additional variations based on fluctuations in market prices, methane production levels, labor cost assumptions, and energy conversion efficiency from methane to electricity. For all scenarios, we calculated the Net Present Value (NPV) and Internal Rate of Return (IRR). The results indicate that, under the conditions of the first scenario group, the investment is not economically viable. In the second group, the investment is justified only under optimistic assumptions. In contrast, the third scenario suggests that the investment could be economically attractive even under current market conditions.
