Competition in electricity markets: international experience and the case of Italy

摘要

As a result of European Directives 96/92 and 2003/54 on the liberalisation of the internal market for electricity, the Italian electricity sector has been subject to extensive institutional changes which have affected the competitive nature of the market. In this paper we attempt to assess the likely effect of these institutional changes on the Italian electricity industry, and focus particularly on the impact of the introduction of a centralised wholesale market. The assessment of the likely impact of these institutional changes is based on the comparison with the international experience of countries where extensive liberalisation measures have been implemented (such as the US, UK and the Scandinavian region). On the basis of this international comparison, we draw some lessons about how to promote effective competition in the Italian market and in other electricity markets which have not been fully liberalised.
