Financial Performance Benchmarking in the Electricity Distribution Indu

A Review of Research Literature Results on Financial Performance Benchmarking in the Electricity Distribution Industry IntroductionSince the late 1980s, there has been earthshaking regulatory reform in the electricity transmission and distribution industries in many countries. Under traditional cost-of-service rate regulation, companies recover their costs to a lower place a regulated rate of return, which may provide little inducing to minimize costs. Alternatively, inducement or performance based regimes are designed to incent productive efficiency by compensating the company for achieving costs savings. Joskow 1 and Joskow and Schlalensee 2 discuss a number of economic regulatory models have been proposed in the literature. According to Jamasb and Pollitt 3, incentive regulation usually involves some form of benchmarking or comparison of existent versus some reference level of performance. We will review the literature results on benchmarking methods for electricity distribu tors.Jamasb and Pollitt 3 published the results of an international survey on the use of benchmarking in incentive regulation of electricity transmission and distribution utilities. Farsi et al. 4 provide a summary of benchmarking methods used in regulation in some(prenominal) countries. some(prenominal) of these survey report cards cite Corrected Ordinary Least Squares (COLS), information Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) as methods unremarkably employed in electricity distribution benchmarking. After briefly describing several models of incentive regulation, we compare the literature results presented in each survey paper ( 3, 4 ) with respect to the techniques mentioned above (COLS, DEA, and SFA). We then present addition results from the literature on th... ...-specific efficiency levels in parametric, semi-parametric and non-parametric settings.
