Abstract

Performance management is one of the most significant strategies in promoting the efficiency of organizations and is highly sensitive. It is important to check the efficiency of combined cycle power plants because of their major contribution to power generation and air pollution. This study was conducted to evaluate the economic and environmental efficiency of Combined Cycle Power Plants (CCPPs). The inputs and outputs required to evaluate the performance of the power plants were determined according to expert opinions. Then, the 7-year statistics and information of the Qom, Neishabour, Shahid Rajaee, Yazd and Kerman power plants were collected as the desired CCPPs in Iran. The Window Data Envelopment Analysis (WDEA) method was used for evaluating the efficiency of the power plants. The 3-year window length showed that most of the power plants were efficient. Only the Rajaee, Neishabour and Yazd power plants were ineffective in some years. The mean efficiency of the power plants in the 4-year window length showed that the plants were efficient from 2008 to 2010.

Summary

Introduction

Whilst considerable variety has been introduced in terms of the sources of supplying electricity, fossil fuels still play a major role in electricity generation [1]. Given the major role of power plants in fuel consumption and air pollution, energy consumption and greenhouse gas emissions must be monitored, which is important in terms of several aspects. It optimizes fossil fuel consumption and reduces fuel consumption, meaning these valuable resources are preserved for the future. Improving air quality can have long-term positive effects on the energy structure and environment [5] In this respect, examining the efficiency of CCPPs given their major contribution to power generation is important
