Elektrische Energie ist nur unter erheblichem technischen und oekonomischen Aufwand zu speichern. Nichtsdestotrotz muss fuer eine zuverlaessige Versorgung der Gesellschaft mit elektrischer Energie ein staendiges Gleichgewicht von Angebot und Nachfrage gewaehrleistet werden koennen. Aus diesem...

Ziel dieses Papers ist es, die derzeitige Diskussion bezueglich des sogenannten 'Merit-Order Effektes' der erneuerbaren Energien auf den Strompreis kritisch zu beleuchten. Veroeffentlichungen, welche diesen Effekt quantifizieren, weisen fuer die Jahre 2005 und 2006 einen Grosshandelsstrompreis...

Ziel dieses Papers ist es, im Hinblick auf die in Deutschland geplante Einfuehrung eines Qualitaetsanreizsystems bei Elektrizitaetsnetzbetreibern, eine geeignete Methode fuer die hierfuer notwendige Bewertung der Netzzuverlaessigkeit - gleichbedeutend mit den wohlfahrtswirksamen...

Since the 1990s, efficiency and benchmarking analysis has increasingly been used in network utilities research and regulation. A recurrent concern is the effect of environmental factors that are beyond the influence of firms (observable heterogeneity) and factors that are not identifiable...

This paper shows how the effect of fuel prices varies with the level of electricity demand. It analyzes the relationship between daily prices of electricity, natural gas and carbon emission allowances with a vector error correction model and a semiparametric varying smooth coef- ficient model....

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>

A linear energy system model is presented which optimises the future development of electricity generation capacities and their dispatch in Europe. Besides conventional power plants, combined heat and power plants and power storages, the model considers technologies that support the future high...

The investment decision on the placement of wind turbines is, neglecting legal formalities, mainly driven by the aim to maximize the expected annual energy production of single turbines. The result is a concentration of wind farms at locations with high average wind speed. While this strategy...

This paper studies the interdependency of a spot electricity market and a market for incremental reserve capacity in a competitive setting, where a continuum of firms supplies both markets. It is proved that a simultaneous competitive equilibrium on both markets exists in the stylised model...
