This article analyses cross-border effects of capacity mechanisms and discusses whether such mechanisms countervail the goals of European Market Integration. Using a two-country-model, the countries' policy options are analysed from a game-theoretical viewpoint. A model simulation identifies the...

Die Zunahme von Netzengpässen durch dezentrale Erzeuger erfordert eine aktive regulatorische Beanreizung von Maßnahmen des Engpassmanagements (EPM) als Alternative zum konventionellen Netzausbau. Gleichzeitig soll der Kostenanstieg mittels Effizienzanreizen begrenzt werden. Für die geplante...

Most transmission systems in Europe are currently in need of large network expansions, in particular to cope with increasing shares of load remote renewable energy sources. Given that the scope for further cost reductions is largely exhausted, we observe a paradigm shift into the direction of...

The purpose of this research is to evaluate the impact of vertical unbundling on German electric utilities. Our research mainly relies on in-depth interviews with sector-experts from the German utilities. We will discuss both short-term changes and the long-term impact on competition in the...

How should we select winning bids of generation units for strategic reserves that consist of capacity bids and energy bids? In this paper, we analyze two selecting mechanisms (scoring rules): "simultaneous" and "sequential". In case of a simultaneous scoring rule, capacity and energy bids are...

In Deutschland wird derzeit die Ausgestaltung der Anreizregulierungsverordnung für Energienetze für die dritte Regulierungsperiode (ab 2019) diskutiert. Im Kern steht der sachgerechte Umgang mit dem hohen Investitionsbedarf, vor dem viele Netzbetreiber stehen. Die preisbasierte...

The German energy transition massively alters the market structure of electricity supply and forces incumbent electric utilities to rethink their business strategies. We analyze three main developments that undermine the former market dominance of the “Big 4” incumbents in Germany. First,...

The factor X in the RPI-X regulation aims to adjust price or revenue allowances to changes in total factor productivity and input prices. A cost Malmquist index can be applied to determine the efficient cost change (ECC). However, regulators typically do not have the necessary data on input...

The rapid growth of Distributed Energy Resources (DER) and their integration into network presents currently the greatest challenges for many network operators worldwide in terms of network stability and power quality. To meet these challenges not only huge investment in grid expansion and smart...

Stromspeicher erscheinen derzeit vor allem in Form von Multi-Use-Speichern wirtschaftlich darstellbar, die nach Bedarf für Netzzwecke eingesetzt werden und um am Strommarkt Handelserlöse zur erzielen. Die technischen Anforderungen aus Netzsicht erfordern in der Regel, dass die Initiative für...
