Das Jahr 2021 hat in Deutschland neuen Schwung in die Bemühungen zum Klimaschutz gebracht. Die Novelle des Klimaschutzgesetzes schreibt eine Reduktion der Treibhausgasemissionen um 65 % bis zum Jahr 2030 gegenüber 1990 fest. Maßgeblich dazu beitragen soll ein massiver Ausbau der...

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...

Market design for electricity often ignores network congestion initially and addresses it in a second, so-called 'redispatch' stage. For market participants, any two-stage design offers an opportunity to strategically optimize between the different market stages. The current debate is how to...

This article presents an approach to minimize the outage costs during power supply disruptions and, thus, to incentivize efficient resilience investment by network users. The central problem to be solved is the information asymmetry between network operators and network users on outage and...

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...

Despite monopolistic networks and in contrast to all other EUmember states, the electricity supply industry in Germany is not ex ante regulated. Control of the sector is left to the cartel agency, which can apply the essential- facilities doctrine as an ex-post instrument. This paper analyses...

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...

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...

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...

The commercial value added in electricity distribution networks and smart grids is increasing. Concerns about competition on a level-playing field are raised and the debate on vertical network unbundling is beginning to address the level of the distribution networks. With regard to the...
