Climate Control Efficiency

G.D. Ferrier and J. G. Hirschberg

Year: 1992
Volume: Volume 13
Number: Number 1
DOI: 10.5547/ISSN0195-6574-EJ-Vol13-No1-3
View Abstract

Abstract:
This paper presents an application of Data Envelopment Analysis (DEA) to energy audit data by defining climate control systems as production processes. This method is proposed as an alternative to the use of regression based models which have been used in previous analyses of this type of data. The advantage of this method is the ability to compute relative efficiency measures for each observation in the data and to define these values without the assumption of a particular specification of the technology. Furthermore, this method can be used with a large number of inputs and outputs.



Measuring Potential Gains from Mergers among Electricity Distribution Companies in Turkey using a Non-Parametric Model

Necmiddin Bagdadioglu, Catherine Waddams Price, Thomas Weyman-Jones

Volume: Volume 28
Number: Number 2

Abstract:
Turkish electricity reform is entering a new phase through the Turkish Government�s proposal to create 21 new distribution companies, 18 of them by merger. Two aspects of merger analysis are the operational cost savings and the potential production efficiency gains. This paper concentrates on the second aspect and uses a recently developed methodology to assess the potential effect of these mergers and whether these mergers are efficiency enhancing. This is performed by comparing the actual efficiency levels of observed distribution companies with the merger of proposed aggregated companies. The model is calibrated on panel data from 1999 to 2003 which include measures of physical capital and labor inputs, as well as customer and energy related outputs. The results indicate potential for considerable efficiency gains from the proposed mergers.



Willingness-to-Pay for Quality of Service: An Application to Efficiency Analysis of the UK Electricity Distribution Utilities

Abstract:
Efficiency analysis of electricity distribution networks is often limited to technical or cost efficiency measures. However, some important non-tradable aspects of their service such as quality of service and network energy losses are often not part of the analysis. Moreover, technical or cost efficiency should not be achieved at the expense of allocative and economic efficiency. Valuation of service quality for regulatory models is particularly difficult. This paper presents an empirical approach to measure and incorporate service quality and energy losses into the analysis of technical and allocative efficiency of the utilities. We apply our method to the case of the distribution networks in the UK between 1990/91 and 2003/04 using the data envelopment analysis technique. We find that the efficiency of the utilities improved during the first and second five-year distribution price control reviews but exhibited a slight decline during the third review period. We find relatively low allocative efficiency � i.e. a mismatch in allocating resources among expenditures, service quality, and network energy losses. The results suggest that currently the utilities may not be correctly incentivised to achieve socially optimal trade-offs between these.

Size, Subsidies and Technical Efficiency in Renewable Energy Production: The Case of Austrian Biogas Plants

Andreas Eder and Bernhard Mahlberg

Year: 2018
Volume: Volume 39
Number: Number 1
DOI: 10.5547/01956574.39.1.aede
View Abstract

Abstract:
This study estimates the efficiency of biogas plants and identifies determinants of inefficiencies. Data Envelopment Analysis is applied on a sample of 86 Austrian biogas plants for the year 2014, covering about one third of the installed electric capacity of Austrian biogas plants. We decompose technical efficiency into scale efficiency and pure technical efficiency (managerial efficiency). In a second-stage regression analysis the effects of subsidies and other variables on managerial efficiency are investigated. The main results are: i) 34% of biogas plants in our sample are technically efficient, 40% are scale efficient and 50% are managerial efficient; ii) small biogas plants (≤100 kW) are scale inefficient exhibiting increasing returns to scale; iii) production subsidies show a significant, negative relationship to managerial efficiency. The results are consistent with the hypothesis that production subsidies provide a disincentive to managerial effort of plant operators.
