Hydro electricity generation is of great importance for the current and the future electricity system since it provides electricity without emitting CO2 and moreover hydro reservoirs offer high operational flexibility. With increasing shares of fluctuating renewable energies, their value is even...

Most electricity systems face contractual fixed consumer prices in the short term, that is, load and price are fixed before the random supply of renewables like wind or solar realizes. Steam power plants also make production decisions before such a random supply realizes. These capacities cannot...

The long-run development of power markets will be deeply affected by the gradual substitution of fossil fuel-based generation technologies by renewable energy technologies (RES). However, the intermittent supply of RES, in combination with the temporal non-homogeneity of electricity demand,...

This article explores key market design issues to be addressed in future electricity markets dominated by intermittent renewable generation with near zero private marginal costs for generating electricity. Changing technology mixes will change market outcomes, but they do not change the...

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...

We analyse in a theoretical framework the link between real-time and day-ahead market performance in a hydro-based and imperfectly competitive wholesale electricity market. Theoretical predictions of the model are tested on data from the Nordic power exchange, Nord Pool Spot (NPS). We reject the...

This paper develops a framework for analyzing the incentives of national transmission system operators (TSOs) to supply cross-border interconnection capacity in an international electricity market. Our results show that equilibrium transmission capacity is downward distorted, even in situations...
