The European Union (EU) third energy package is in the process of being implemented (see EU 2009a, 2009b) and should be finalized by 1 March 2011. While the main aim of ownership unbundling was not politically feasible, it is possible that this issue may be further addressed in a future fourth energy package. The main focus of this contribution will be on the effects of ownership unbundling on infrastructure investment and usage. Above all, this concerns interconnector capacity. In 2007, the EU Commission presented the so-called sector inquiry,2 in which it assessed the developments of competition and liberalization of the European energy markets. The developments were deemed to be disappointing. The developments in electricity markets were slow but nevertheless encouraging, while in the gas markets the developments were simply too slow. This raises two questions which are addressed in this contribution. First, how much can (network) unbundling contribute to an improvement of lagging competition?
