In the present work the thermal systems in a combined cycle for power generation were modelled, allowing to predict the performance of this systems in a case study of a sugar mill with distillery, where the fuel is a limited amount of biomethane. The developed models were used to create a working alternative of combined cycle with gas turbine at full load and without supplemental firing; another alternative was modelled with gas turbine at partial load operation and additional combustion in the HRSG; both alternatives were evaluated with energy efficiency and fuel consumption ratio. The working alternative where the gas turbine operates at partial load operation resulted in the highest power generation and also the most thermodynamically efficient, generating 7490, 03 kW with 42,99% of energetic efficiency. An economic feasibility analysis of the investment in both alternatives was carried out, which exposed that the combined cycle alternative without supplemental firing is also the most economically sustainable, with revenues of 916427 USD and 1408686 USD of VPN.
