Renewable energy sources (RES) play an increasing role in many electricity systems thanks to climate and support policies and subsequent cost reductions in recent years. Compared to conventional generation technologies, RES has two main important distinctive features: First, their cost pattern...

From 2002 to 2006, German wholesale electricity prices more than doubled. The purpose of this paper is to estimate the price components in 2006 in order to identify the factors responsible for the increase. We develop a competitive benchmark model, taking into account power plant...

The liberalization of the electricity sector increases the need for realistic and robust models of the oligopolistic interaction of electricity firms. This paper compares the two most popular models: Cournot and the Supply Function Equilibrium (SFE), and tests which model describes the observed...

This paper analyzes the interdependence of reserve and spot markets for electricity applying equilibrium models. We develop a Cournot model to analyze the impact of different pricing mechanisms at the reserve market (uniform and pay-as-bid) on spot market prices. Furthermore, we show how the...

This paper provides a description of ELMOD, a model of the European electricity market including both generation and the physical transmission network (DC Load Flow approach). The model was developed at the Chair of Energy Economics and Public Sector Management (EE2) at Dresden University of...

During 2004 and 2006 German wholesale electricity prices nearly doubled. The purpose of this paper is to estimate the factors for this price increase differentiated by fuel costs, CO2-emission allowances, and market power. We develop a competitive benchmark model, taking into account power plant...

This paper compares the results of different pricing systems in the German electricity sector. In particular,we compare a competitive nodal pricing approach to a cost minimization scenario under a uniform price. The model also simulates the effects of increasing offshore wind energy in the North...

In this paper, we apply the theory of nodal pricing to a particularly urgent issue of energy and environmental economics: the integration of wind power in electricity systems. We use a nodal pricing model to analyze the impact of German wind power production on the North Western European power...

This paper examines the Hogan-Roselloacute;n-Vogelsang (2007) (HRV) incentive mechanism for transmission expansion, and tests it for different network topologies. This new mechanism is based upon redefining transmission output in terms of point-to-point transactions or financial transmission...
