The management of congestion within the German electricity transmission network has become more important during the last years. This emerging relevance is caused by the increase of renewable generation and the partial phaseout of nuclear power plants. Both developments yield a change in the...

Trotz des Atommoratoriums aus dem März 2011 ist die Versorgungssicherheit des deutschen Stromsystems bisher nicht gefährdet gewesen und auch für das kommende Jahrzehnt ist keine Gefährdung abzusehen. Derzeit hat das System aufgrund des Zubaus konventioneller Kraftwerke sowie der erneuerbaren...

A shift from zonal pricing to smaller zones and nodal pricing improves efficiency and security of system operation. Resulting price changes do however also shift profits and surplus between and across generation and load. As individual actorscan lose, they might oppose any reform. We explore how...

We analyze the current regulatory regime for electricity transmission in Germany, which combines network planning with both cost-plus and revenue-cap regulations. After reviewing international experiences on transmission investment, we first make a qualitative assessment of the overall German...

A shift from zonal to nodal pricing improves the efficiency of system operation. However, resulting price changes also shift surplus across generation and loads at different locations. As individual actors can lose, they might oppose any reform. We explore how allocation of financial...

In spite of the March 2011 nuclear moratorium, the German electricity system's ability to provide a secure supply has not been jeopardized to date, and there is no prospect of this occurring in the coming decade, either. The system currently has major overcapacities due to construction of...

This paper, which examines the impacts of phasing out nuclear power in Germany, is the first to include an analysis of energy supply security and critical line flows in both the German and Central European electricity networks. The technical-economic model of the European electricity market,...
