Does Weather Have an Impact on Electricity Distribution Efficiency? Evidence from South America
نویسندگان
چکیده
This paper evaluates a more integrated approach of regulation when doing international comparisons and represents the first cross-country study in the South American region in which quality and weather variables have been included in the analysis. A total of 82 electricity distribution firms operating in Argentina, Brazil, Chile and Peru have been analysed for the period 1998-2008. Stochastic frontier analysis (SFA) is the method selected. Even though there is no special preference in using parametric or non-parametric methods, SFA was selected in this study mainly due to its capability to split the error term into two different components. Cost models and cost-quality models are analysed.

Does Weather Explain the Cost and Quality? An Analysis of UK Electricity Distribution Companies
In recent years, a number of empirical studies and energy regulators have applied benchmarking techniques to measure the efficiency and performance of network utilities. An important issue has been the extent to which such results are influenced by contextual factors. Among these, weather factors are frequently discussed as being important. We use Factor Analysis and two-stage Data Envelopment ...

متن کاملThe Case for International Coordination of Electricity Regulation: Evidence from the Measurement of Efficiency in South America
A decade long experience shows that the monitoring of the performance of public and private monopolies in South America is proving to be the hard part of the electricity sector reform, due to the operators control of most of the specific information needed for regulatory purposes. This paper argues that, in spite of, and maybe because of, a much weaker information base and governance structure...

Efficiency analysis plays an important role in price regulation in the electricity distribution sector. This paper analyses efficiency and productivity of 38 electric distribution companies in Iran from year 1387 to 1389 (Iranian calendar year) by using slack based model (SBM). Super efficiency analysis is employed to rank full efficient companies. According to results, Tabriz, Ahwaz and north ...
