Viability studies

Viability studies of technical-economic Cogeneration Projects.

Preliminary study of the thermal demand and of the electrical consumption.

Determining the most suitable prime mover: gas turbine or gas engine.

Energy and mass balances and calculation of the thermodynamic performances of the Cogeneration plant: REE and PES.

Energy comparison comparing the plant with and without Cogeneration.

Investment: detailed estimation of Cogeneration plant.

Ascertaining the clear savings of investment in the Cogeneration plant and indexes of the viability of the investment: Current Net Value and Internal Return Rate.
