What is a good balance between competition and coordination in network industries? Network unbundling aims to promote competition, but this has to be balanced against the downside of unbundling: firm-internal coordination falls away and must be replaced by external market mechanisms. This is a...

Electricity networks currently face massive investment requirements. This paper argues that, given the investment requirements, (international) benchmarking is not an adequate tool for the regulation of transmission system operators (TSO). Errors in the outcomes of benchmarking will likely...

The purpose of this research is to evaluate the impact of vertical unbundling on German electric utilities. Our research mainly relies on in-depth interviews with sector-experts from the German utilities. We will discuss both short-term changes and the long-term impact on competition in the...

This paper explores the relation between the regulation of monopolistic upstream prices and the incentives of a vertically integrated input monopolist to discriminate third parties on the downstream market. Currently, this is an issue in network industries like telecommunications, electricity...

This paper presents an approach for resilience incentives in the regulation of electricity network operators. Resilience is the ability of the power system to deal quickly and efficiently with large-scale and long-lasting power interruptions. It comprises two related aspects: minimizing the...

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...

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,...

Merchant electricity transmission investment is a practically relevant example of an unregulated investment with monopoly properties. However, while leaving the investment decision to the market, the regulator may decide to prohibit capacity withholding with a must-offer provision. This paper...

This paper discusses unregulated market-based electricity transmission investment by third parties as opposed to regulated investment by designated transmission system operators. The analysis is set against a European and Australian institutional background and focuses on interconnection of...

The German energy industries will be subjected to regulation of network access enforced by a sector-specific regulator. Whereas the gas industry broke the regime of negotiated third party access, in electricity nTPA ‘worked’, although it clearly resulted in a margin squeeze. The government...
