Economic evaluation of the different fuel types utilization in Qayyarah gas power plant.

The main problem of gas generating units that operate in the simple cycle system is their relatively low thermal efficiency, which results in a large waste of heat energy resulting from the fuel combustion process. The current research is aimed to study the economic evaluation of the different types of fuel in the Qayyarah gas power plant. Gas turbine unit field data for the year 2021, with the months of January in winter, April in spring, July in summer, and October in autumn, were used for this research. Study results showed that, light fuel is more expensive by 90% than natural gas and 94% than crude oil, and therefore it cannot be used for the permanent operation of the gas turbine because of its high cost and the lack of local product from it. The production cost of (KWH) for the three types of fuel is variable in the four seasonal months, where the month of July is a high cost due to the demand for electricity due to the high air temperature in that month, while the month of April was less expensive due to the mild conditions, low SPICIFIC fuel consumption and the low demand for electricity.
