Abstract
The constant increasing in the electricity price and its high cost at peak hours encourages the search for alternatives to reduce cost. A option is the use of a genset to supply electricity and use its exhaustion gases energy for thermal application. Currently, many companies already use gensets at peak hours to reduce the energy bill, however without using the exhaustion gases thermal energy. This work carries out a technical-economic feasibility analysis of a genset providing electricity and simultaneously using its heat from the exhaust gases as a thermal source for an absorption cooling system, operating full time and also only during peak hours, and comparing its operation cost against the current energy consumption cost of the Belem-Br international airport. The results showed that the coolinggenerator system operating full-time and at peak hours proved to be economically unfeasible due to the current price of the diesel fuel. However, it was observed that the use of only the genset at peak times for electricity generation proved to be economically feasible, with a significant reduction in the electricity bill.
