This paper conducts an empirical analysis of risk premiums in the German day-ahead Electricity Wholesale Market. We compare hourly price data of the European Energy Exchange (EEX) auction and of the continuous over-the-counter (OTC) market taking place prior to EEX. As OTC price data are not...

Ziel dieses Papers ist es, im Hinblick auf die in Deutschland geplante Einführung eines Qualitätsanreizsystems bei Elektrizitätsnetzbetreibern, eine geeignete Methode für die hierfür notwendige Bewertung der Netzzuverlässigkeit gleichbedeutend mit den wohlfahrtswirksamen Stromausfallkosten...

Der An-und Verkauf von Erdgas an Großhandelsmärkten wird in einem zunehmend liberalisierten Gasmarkt auch in Kontinentaleuropa weiter an Bedeutung gewinnen. Die Preise an diesen Märkten bilden sich aus Angebot und Nachfrage; wie in jeder netzgebundenen Industrie kommt der Infrastruktur und...

Due to the increasing European import dependency, significant additional natural gas volumes will be required. In addition to the Nord Stream pipeline, the Nabucco and South Stream pipeline are projects planned for the next decade to provide further gas supplies to the European market. As one of...

Europe's increasing import dependency in natural gas facilitates a number of new infrastructure projects. However, up to now it has always been difficult to assess the full impact of these projects as interdependencies within the whole European gas infrastructure system were hard to predict. We...

Ziel dieses Papers ist es, die derzeitige Diskussion bzgl. des sog. Merit-Order Effektes der erneuerbaren Energien auf den Strompreis kritisch zu beleuchten. Veröffentlichungen, welche diesen Effekt quantifizieren, weisen für die Jahre 2005 und 2006 einen Großhandels-Strompreis senkenden...

Especially in the short-term, prices in natural gas markets are not exclusively determined by overall supply and demand, but also by the availability of the transport infrastructure. If transportation capacity is scarce, prices may form in (local) residual markets and can differ regionally. If...

This article analyses the flexibility of the German power market with respect to the integration of an increasing share of electricity from renewable energy sources. Flexibility limiting system components, which cause negative prices are explained and illustrated for the German market. Then, the...

This paper investigates the benefits of a merger when goods are complements and firms behave in a Cournot manner both in a theoretical model as well as in a real-world application. In a setting of two complementary duopolies a merger between two firms each producing one of the goods always...

System security in electricity markets relies crucially on the interaction between demand and supply over time. However, research on electricity markets has been mainly focusing on the supply side arguing that demand is rather inelastic. Assuming perfectly inelastic demand might lead to delusive...
