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...

This paper provides a formal analysis on the investment coordination problem in a vertically separated electricity supply industry, although the analysis may apply also to other network industries. In an electric- ity system, the investment decisions of network and power plants need to be...

Most transmission systems in Europe are currently in need of large network expansions, in particular to cope with increasing shares of load remote renewable energy sources. Given that the scope for further cost reductions is largely exhausted, we observe a paradigm shift into the direction of...

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...

How should we select winning bids of generation units for strategic reserves that consist of capacity bids and energy bids? In this paper, we analyze two selecting mechanisms (scoring rules): "simultaneous" and "sequential". In case of a simultaneous scoring rule, capacity and energy bids are...

Smart contracts based on voluntary participation and optionality can be a low transaction cost solution to implement locational signals in distribution networks and thereby avoid network investment. This paper examines the efficiency properties of smart contracts. Based on a three-node example...

This paper contributes a theoretical analysis of the effects of different types of regulation on the timing of monopoly investment in a setting with lumpy investment outlays. Concentrating on the case where investment increases the regulatory asset base, we distinguish between price-based...

In an intertemporal model, we analyze the timing of irreversible and lumpy monopoly investment under certainty. There are two reasons for investing, i.e. wear and tear leading to replacement investment and demand growth leading to expansion investment. Both in a single investment setting and in...

In response to the global climate challenge many countries are faced with increasing shares of energy from renewable sources in their power supply. The integration of RES (renewable energy sources) generation however entails technical as well as institutional challenges for power grids. This...
