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...

The increasing share of renewables in the electricity system results in congestion on all network levels. To address this congestion, the EU Commission proposed that distribution network operators become responsible for local congestion management. Within this paper we analyze the institutional...

The unbundling of formerly vertically integrated utilities in liberalized electricity markets led to a coordination problem between investments in the regulated electricity grid and investments into new power generation. At the same time investments into new generation capacities based on...

Restricted participation in sequential markets may cause high price volatility and welfare losses. In this paper we therefore analyze the drivers of restricted participation in the German intraday auctin which is a short-term electricity market with quarter-hourly products. Applying a...

Analyzing commodity market dynamics, we observe that price volatility increases with reduced contract duration. In this paper, we derive a theoretical model depicting the price formation in two markets with altering product granularity. Supplemented by empirical evidence from German electricity...

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...

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...

This paper looks at the restructuring of European electricity markets that has been taking place since the 1990s. This liberalisation process, driven largely by EU legislation aiming to create a single market for electricity, has led to significant changes in how electricity markets in member...

With a growing number of distributed energy resources, the electricity network is challenged with a higher quantity of technical problems such as capacity congestions and over- or under-voltages. One often-discussed approach to solve these problems, especially in the European zonal electricity...

An important goal of the European Commission is the promotion of the internal energy market (here specifically electricity), which requires sufficient and adequate cross-border interconnector capacity. However, cross-border interconnector capacity is scarce and, more importantly, the progress of...
