This article presents analysis of the biogas-fueled reciprocating engine application in a wastewater treatment plant.
From the data obtained from the operator (a specific wastewater treatment plant in Poland), a specified model of cogeneration
engine was selected. The study also discusses the fundamental correlations associated with the energy-intensive process of
wastewater treatment. In addition to determining the break-even price of electricity, this paper provides a detailed economic
analysis of the net present value (NPV). This article also includes a sensitivity analysis, taking into account changes in capital
expenditures, weighted average cost of capital (WACC), and loan interest rates. The results demonstrate the economic viability
of using biogas-fueled cogeneration systems in wastewater treatment plants.
