Sizing of electric power generation systems from biogas through the generator staggering methodology

Abstract

We developed the generator scheduling methodology proposed in this work to make electricity generation more efficient in installations that have a variable biogas production profile. The method was applied at the Baldo/CAERN sewage treatment plant. In this application we retrieved a Net Present Value of R$ 46,356,973,80 for the generation system during 20 years, with a Cost Benefit Index of 2.85, which showed the large financial profitability of the project, derived from the efficient usage of the biogas provided by the developed methodology.
