From 1992 to 2002, major expansions of the Argentine electricity transmission sector depended on users proposing, voting and paying for such expansions, which were then put out to competitive tender. Commentators hold this novel policy to have been unsuccessful, mainly on the ground that it...

Demsetz (1968) advocated competitive bidding as a replacement for natural monopoly regulation. Williamson (1976) and Goldberg (1976) argued that these problems of natural monopoly regulation are inherent in long-term investment under uncertainty, and that both long- and short-term franchising...

This paper supplements analyses of Argentine transmission expansions at the federal level by looking at experience in Buenos Aires province. A Regional Electricity Forum of distribution companies has drawn up and begun to implement a ten-year transmission expansion plan. Contrary to previous...

We develop a stochastic two-stage optimisation model that captures the multistage nature of electricity transmission planning under uncertainty and apply it to a stylised representation of the Great Britain (GB) network. In our model, a proactive transmission planner makes investment decisions...

This paper discusses some of the new and continuing ways in which the public sector is involved in the electricity / energy sector around the world. This involvement continues to be significant in spite of the longrunning trend towards privatisation, competition and independent regulation in the...

Efficiency and productivity analysis is a central concept in incentive-based regulation of network utilities. However, the efficiency measures obtained from benchmarking predominantly reflect short term performance and hence, provide only a snapshot of the firm's path towards its long run...

This paper applies the concept of regulatory threat to analyse the electricity supply industry in Germany, where in contrast to other European member states, there is no ex-ante regulation of network access charges. Instead, network access relies on industrial self-regulation and ex-post control...

In the UK, domestic customers must be able to terminate energy contracts at 28 days’ notice. This has been seen as a transitional protection for customers and for competition. This paper reviews the arguments for and against the 28 day rule, and examines the extent to which UK suppliers have...

This paper presents a social cost benefit analysis of ownership unbundling (as compared to legal und functional unbundling) of the electricity transmission system operators in Germany. The study relies on the Residual Supply Index for its competitive concept. The analysis models some 15 effects,...

Auctions are playing an increasingly prominent role in the planning and operation of energy markets. Comparing the New Electricity Trading Arrangements to the former electricity Pool in England and Wales requires some analysis of the relative merits of uniform versus discriminatory pricing...
