“…They developed a DEA model in two stages, using Bootstrap; in Stage 1 they calculated technical efficiency and in Stage 2 they incorporated exogenous variables. In the same direction, Pahwa et al (2003) conducted a benchmarking analysis of the distribution process of the electric sector applying the DEA methodology to 50 companies that offer electric distribution service in the USA, as well as De Quadros Martins et al (2018), calculated technical efficiency with DEA methodology, of 18 electricity distribution companies in Brazil.…”

Purpose The purpose of this paper is to determine the level of efficiency in the Mexico electricity industry during the 2008-2015 period. Design/methodology/approach A data envelopment analysis (DEA) network model is proposed, where technical efficiency is calculated. A factorial analysis using the principal components method was carried out first. Later, latent dimensions were calculated through the variance criterion and sedimentation graph, where four components were presented. After performing factor rotation, the nodes were grouped: generation, transmission, distribution and sales. It proceeded later to structure a DEA network model. Findings From the calculations made, the most efficient node was the transmission, while the North Gulf and East Center divisions were the only efficient. Research limitations/implications The limitations presented in this study were data collection. Practical implications The implications that were observed were that through the results obtained, proposals can be made to the Mexican electricity sector to improve each of the nodes, and have a better operation and reduce energy losses. Social implications The social impact of this type of study is that based on the results obtained, they present the basis for improving energy policy and users can have a better service that has better quality and coverage. Originality/value The originality of this study consists in the use of two methodologies, factor analysis methodology and DEA network model.

Electric Industry. After two decades of EPIRA’s enactment, it is essential to assess where in the Distribution Sector, the reform’s trajectory has stalled. The study aimed to examine and assess the technical and operational efficiencies of the top five electric private distribution utilities (PDUs) in the Philippines under the regulatory policy. Methodology: This is a causal-comparative study using a panel data structure on technical and operational efficiencies of the top five PDUs in the Philippines from 1995 to 2014, employing quantitative measurement. This study used Data Envelopment Analysis (DEA) as the non-parametric test while Stochastic Frontier Analysis (SFA) as the parametric approach. Main Findings: Using the Stochastic Frontier Analysis (SFA) model showed that the implementation of EPIRA (post-EPIRA: 2001 to 2014) made the top five electric private distribution utilities in the Philippines more technically efficient in their operations than without the reform (pre-EPIRA: 1995 to 2000). It was also noted that PDUs with bigger franchise areas and older in existence were technically efficient in their operations than their smaller and younger PDUs counterpart, respectively. Applications: This study will enhance public awareness in the various assessment of regulatory policy arenas in PEI. Moreover, this study will also render useful insights into the management of DUs in the Philippines. Novelty/Originality of this study: An up-to-date empirical analysis of the situation to substantiate the claim of the reform’s efficiency in the Philippines is lacking in the literature. This paper is thus providing a comprehensive theoretical debate by examining some indications of EPIRA's efficiency in the Distribution Sector in the Philippines.

Este artigo analisa a eficiência técnica relativa das empresas brasileiras distribuidoras de energia elétrica. A busca por eficiência tem sido constante em muitos setores e a indústria representa uma importante fonte de desenvolvimento econômico para o país. As distribuidoras de energia elétrica passaram por maiores transformações devido a transferência de controle acionário para empresas privadas. A pesquisa possui característica descritiva e abordagem quantitativa, utilizando como técnica de pesquisa a Análise Envoltória de Dados (DEA) realizada com base em dados de 2012. Identificou-se que apenas 1 em 17 distribuidoras de energia elétrica foram consideradas tecnicamente eficientes. As empresas COSERN e a RGE são os melhores benchmarks para as empresas ineficientes e são detentoras de diferentes prêmios de qualidade e gestão do setor. A variável que mais contribuiu para os escores de eficiência das empresas foi a variável Potência Instalada e as variáveis que necessitam de melhorias são o Desempenho Global de Continuidade e Tempo Médio de Atendimento.
