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...

In this working paper we demonstrate how challenging greenhouse gas reduction targets of up to 95% until 2050 can be achieved in the German electricity sector. In the analysis, we focus on the main requirements to reach such challenging targets. To account for interdependencies between the...

During 2007 and 2008 steam coal prices soared to unprecedented levels. Since then much has been speculated about the drivers of these price peaks. This paper is concerned with the costs of steam coal allocation in the seaborne market and their influence on the price equilibrium. It presents an...

In this work we demonstrate the effects of different Chinese transport infrastructure investment strategies on long run marginal costs of steam coal supply in Europe. <p> Increasing Chinese demand for steam coal will lead to a growing need for additional domestic infrastructure in China as...</p>

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

In the aftermath of the nuclear catastrophe in Fukushima, German nuclear policy has been reconsidered. This paper demonstrates the economic effects of an accelerated nuclear phase-out on the German electricity generation sector. <p> A detailed optimization model for European electricity markets is...</p>

In this paper, we develop a methodology for deriving a consistent measure for supply adequacy in the power generation sector. We especially consider the secured generation capacity of intermittent renewable energy sources such as wind. <p> Availability of conventional power plants is estimated...</p>

We explore the hypothesis that export policies and trade patterns of national players in the steam coal market are consistent with non-competitive market behavior. We test this hypothesis by developing an equilibrium model which is able to model coal producing nations as strategic players. We...

The seaborne steam coal market changed in recent years. Trade volumes grew dynamically, important players emerged and since 2007 prices increased significantly and remained relatively high since then. <p>In this paper we analyse market equilibria in the years 2006 and 2008 by testing for two...</p>

Renewable energies are meant to produce a large share of the future electricity demand. However, the availability of wind and solar power depends on local weather conditions and therefore weather characteristics must be considered when optimizing the future electricity mix. <p>In this article we...</p>
