This paper uses a bi-level game to model markets for delivery of electrical power on looped transmission networks. It analyzes the effectiveness of an independent system operator (ISO) when generators (and, in some cases, retailers) with market power bid a single parameter of their linear supply...

This study explores and quantifies the benefits of connecting more distributed generation (with and without the use of smart connections) across different parties (Distribution Network Operators, wider society and generators). Different connection scenarios are proposed (with partial and full...

Since 2008 UK energy regulator Ofgem has imposed increasingly severe restrictions on suppliers to the domestic (residential) retail market. Initially, non-discrimination conditions aimed to “remove unfair price differentials”, particularly between suppliers’ prices between regions,...

Interstate gas pipelines and their customers presently settle about 90% of the rate cases set for hearing before the Federal Energy Regulatory Commission (FERC). In recent years, the median time for negotiating settlements and having them approved is about 11 months, compared to several years to...

The UK utility regulation framework developed in the 1980s was intended to improve on the restrictive, inefficient and burdensome regulatory approach in the US. But the UK regulatory process has itself now become increasingly burdensome. Meanwhile, utilities and customer groups in the US and...

Economists acknowledge the problems of regulated transmission but take different views about the likely efficiency of merchant transmission. This paper examines the evidence on alleged market failure and regulatory failure as experienced in practice in Australia and Argentina. In these examples,...

The literature shows that for most UK industries privatization might be necessary but is not sufficient to produce economic benefits. Often prior changes in management or later changes in market structure and regulation have larger impacts than privatization itself. We ask what changes around...

Incentive regulation and efficiency analysis of network utilities often need to take the effect of important external factors, such as the weather conditions, into account. This paper presents a method for estimating the effect of weather conditions on the costs of electricity distribution...

Since the 1990s, efficiency and benchmarking analysis has increasingly been used in network utilities research and regulation. A recurrent concern is the effect of environmental factors that are beyond the influence of firms (observable heterogeneity) and factors that are not identifiable...

This paper studies the impact of divestiture on the efficiency and costs of electric utilities. The empirical literature shows that there exist economies of scope for electric utilities and that divestiture decreases distribution efficiency but increases generation efficiency. This paper is to...
