Nodal pricing has emerged from a theoretical approach to a practicable and efficient tool for network and congestion mangement. Experiences from North America and New Zealand have proven nodal pricing to be workable without serious technical problems. Continental European electricity grids like...

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...

Wind energy has become the major renewable energy source in Germany with an installed capacity of more than 20 GW and an annual output of about 40 TWh in 2007. In this paper we analyze the extent to which wind energy can replace fossil capacities based on wind injection and demand data for 2006...

The reliability of the electricity grid is of vital significance for the proper functioning of a society and its economy. The aim of this study is to develop a methodology to quantify differences in the electricity distribution grid's economic importance, and investigate limitations for its...

The German Energiewende’s potential effects on the reliability of electricity supply as well as the corresponding economic consequences have recently entered both the political and scientific debate. However, empirical evidence of power outage costs in Germany is rather scarce. Following a...

In German electricity submarkets for residential customers standard contracts offered by former monopolists are the more costly option for customers who have not switched to an alternative contract yet. As most German households are served with this contract type we follow the Limit Pricing...

While liberalization in energy markets has been a widely successful process all over the world, incumbents often still hold a dominant position. Thus, electricity wholesale markets are subject to market surveillance. Nevertheless, consolidated findings on abusive practices of market power and...

In this paper we present an international cross-country benchmarking analysis for utility regulation of France and Germany, the two largest electricity distribution countries in Europe. We examine the relative performance of 99 French and 77 German distribution companies operating within two...

It is the objective of this paper to quantify the significance of fundamental factors (like rising fuel costs) and of the increasing exercise of market power on rising prices in the German wholesale electricity market. A successive MIP/LP approach was used for this. The calculations show that,...
