Efficiency assessment of Turkish power plants using data envelopment analysis

Data envelopment analysis (DEA) is a linear programming based data analytic method for measuring the relative efficiency of organisational units where the presence of multiple inputs and outputs makes comparisons difficult. Academic departments have critical importance for a university so we agree to research and compare about academic faculties in a leading university in Turkey. The aim of the study is to measure the relative efficiency of the academic faculties and determine the efficient/inefficient ones in the studied university. 12 faculties of the university are investigated within the scope of this study. The input variables are considered as total number of academic staff, total number of non-academic staff, number of students and the output variables are as number of publications, number of projects and the percentage of budget used. While results of CCR model show an average of 90.5% relative efficiency value, five faculties are found 100% efficient according to the CCR model. According to BCC model, the results have an average of 93.7% and 6 faculties are 100% efficient. In terms of the potential improvements evaluated for each inefficient faculty, it is seen that faculty of mechanical engineering and faculty of civil engineering are the ones requiring the most improvement. This paper contributes to the literature a lot however it is a new and proper study on efficiency analysis of faculties of a Turkish university. On conclusion of the DEA efficiency scores, the existence of misallocation of resources or/and inefficient applications to the faculties' academic development are uncovered.

“…It is a performance measurement technique which, can be used for evaluating the relative efficiency of decision-making units (DMU's) 1 in organizations. The most basic DEA model is CCR based on Charnes, Cooper & Rhodes (1978) which have constant returns to scale; however there is also DEA models which address varying returns to scale known as BCC based on Banker, Charnes and Cooper (1984) [11].…”

“…A similar had been followed by India which experienced electric power reforms in early 1991. Today's competitive electricity market has heightened the need for methods to evaluate the technical efficiency of the electric utility [1]. Among many possible efficiency measurement methods, Data Envelopment Analysis (DEA) is one method that has been used especially for the complicated systems with lots of inputs and outputs for benchmarking since its introduction by Charnes, Cooper and Rhodes in 1978 based on previous work by Farrell on production efficiency [2].…”

Technical efficiency of electric utility is the critical element for its competitiveness in the electricity market and very relevant in the Indian electricity sector presently. This paper is aimed to measure the efficiencies of 30 state owned electric generation utilities/companies for the year 2007-08 by applying DEA models with single input and two outputs. The input used is total cost and outputs are units of energy generated and total energy sold or consumed. Cost benchmarking has been carried out so that cost controls can be implemented. In addition, the target evaluation for input cost has also been done. The result of this model shows that GENCOs are generally inefficient in cost frontier and there is an urgent need for intro inspection. This will help for GENCOs. The result shows that the total average of overall, technical and scale efficiencies are 46%, 75.1% and 60% respectively. This efficiency measurement assists the utilities by identifying their shortcomings, setting targets and trying to reach the set targets.

“…In this regard, type of source, efficiency and ownership of power plants are key characteristics to be investigated, in answering the question ''Which one is better with respect to others and why?''. Many studies involving comparisons among types of power plants have been made in order to obtain the best answer to this question 1 . This study involves a multi-input-multi-output performance evaluation and comparison of a set of power plants in Turkey based on real data.…”

In this study, we consider data envelopment analysis for comparison between thermal energy plants which are natural gas based and coal based power plants. Results of this study will give a roadmap to decision makers in selecting type of thermal plant they will construct. Also public and private energy supply sources are compared based on their performances. We not only make a solely comparison but also make a ranking of the power plants considered by using goal programming technique.
