Liberalized electricity markets are characterized by fluctuating price-inelastic demand of non-storable electricity, often defined by a substantial market share held by one or few incumbent firms. These characteristics have led to a controversial discussion concerning the need for and the design...

We study two electricity markets connected by a fixed amount of crossborder capacity. The total amount of capacity is known to all electricity traders and allocated via an auction. The capacity allocated to each bidder in the auction remains private information. We assume that traders are faced...

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...

Electricity market models, implemented as dynamic programming problems, have been applied widely to identify possible pathways towards a cost-optimal and low carbon electricity system. However, the joint optimization of generation and transmission remains challenging, mainly due to the fact that...

Unter dem Merit-Order-Eekt (M-O-E) der erneuerbaren Energien (EE) wird deren preissenkende Wirkung auf die Strompreise auf Großhandelsebene (Börsenpreise) verstanden. Sowohl die Höhe des Merit-Order-Effekts in der kurzen und der langen Frist als auch dessen volkswirtschaftliche Bedeutung ist...

Liberalization of network industries frequently separates the network from the other parts of the industry. This is important in particular for the electricity industry where private firms invest into generation facilities, while net- work investments usually are controlled by regulators. We...

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>

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...

The European Commission has intensively discussed the mandatory separation of natural gas transmission from production and services. However, economic theory is ambiguous on the price effects of vertical separation. In this paper, we empirically analyse the effect of ownership unbundling of...
