Examination of the Factors Affecting the Efficiency of Gas Power Plants

Due to the growing demand for electricity it is inevitable to have new power plants. Given the large share of electricity production in thermal power plants, construction of gas burning power plants have particular importance. Because of the high construction cost of the new plants, it is advisable to start with improvement of the efficiency in the existing and plates. One important index in electricity industry, is the efficiency of power plants which concerns all the powerplants in the world. In order to increase it as much as possible, and reduce the loss of energy to a reasonable degree, this paper examined the performance impact of plant life and obtained 0.07 of electricity coefficient for the variable. We also examined other factors related to efficiency. Among the factors influencing efficiency of this type of power plants, the cost of fuel and average plant life and volume of production of electricity were also important. In this study a panel data from 34 gasplants in Iran was used for a period of 4 years (2008-2011)
