Competition and Access in Electricity Markets: ECPR, Global Price Cap, and Auctions

CIRANO Le CIRANO est une corporation privée à but non lucratif constituée en vertu de la Loi des compagnies du Québec. Le financement de son infrastructure et de ses activités de recherche provient des cotisations de ses organisations-membres, d=une subvention d=infrastructure du ministère de l=Industrie, du Commerce, de la Science et de la Technologie, de même que des subventions et mandats obtenus par ses équipes de recherche. La Série Scientifique est la réalisation d=une des missions que s=est données le CIRANO, soit de développer l=analyse scientifique des organisations et des comportements stratégiques. CIRANO is a private non-profit organization incorporated under the Québec Companies Act. Its infrastructure and research activities are funded through fees paid by member organizations, an infrastructure grant from the Ministère de l=Industrie, du Commerce, de la Science et de la Technologie, and grants and research mandates obtained by its research teams. The Scientific Series fulfils one of the missions of CIRANO: to develop the scientific analysis of organizations and strategic behaviour. Ce document est publié dans l=intention de rendre accessibles les résultats préliminaires de la recherche effectuée au CIRANO, afin de susciter des échanges et des suggestions. Les idées et les opinions émises sont sous l=unique responsabilité des auteurs, et ne représentent pas nécessairement les positions du CIRANO ou de ses partenaires. This paper presents preliminary research carried out at CIRANO and aims to encourage discussion and comment. The observations and viewpoints expressed are the sole responsibility of the authors. They do not necessarily represent positions of CIRANO or its partners. In this paper, we first review in this paper some general principles and fundamental facts and issues which remain at the heart of the movement towards deregulation, restructuring and privatization in network industries in general and in the electricity industry in particular. We then proceed with a discussion of a set of basic procedures through which competition can be introduced in electricity markets, that is the access pricing rules. We compare the efficient component pricing rule with the Ramsey-Boiteux pricing rule and we discuss the global price cap rule. We finally discuss some real world experiences (UK and Canada) and we present some recent ideas on network access auctions as a possible approach to increasing competition with soft or light-handed regulation. We conclude by raising some issues which have been relatively neglected but remain nevertheless important.
