There is a public perception that electricity liberalisation is the major cause of recent electricity blackouts. This is reflected in the newspaper reporting of blackouts. By contrast, it was not listed as a cause in any official investigation reports. In this paper, we examine the common causes...

The world-wide electricity sector reforms have led to a search for alternative and innovative approaches to regulation to promote efficiency improvement in the natural monopoly electricity networks. A number of countries have used incentive regulation models based on efficiency benchmarking of...

In order to achieve overall economic efficiency, incentive regulation of electricity distribution utilities must address two important and inter-related issues. First, the utilities’ allowed revenues need to be set at correct levels. Second, the access charging mechanism by which the utilities...

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...

Since the early 1980’s, many countries have implemented electricity sector reform, many of which have bundled generation, transmission, distribution and supply activities, and have introduced competition in generation and supply. An increasing number of countries are also adopting incentive...

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 generally not part of the analysis. A regulatory concern is...

Quality of service is of major economic significance in natural monopoly infrastructure industries but is generally not reflected in efficiency analysis. In this paper we present an efficiency analysis of electricity distribution networks using a sample of about 500 electricity distribution...
