We analyze the treatment and impact of idiosyncratic or firm-specific risk in regulation. Regulatory authorities regularly ignore firm-specific characteristics, such as size or asset ages, implying different risk exposure in incentive regulation. In contrast, it is common to apply only a single...

Since the 1990s, efficiency and benchmarking analysis has increasingly been used in network utilities research and regulation. A recurrent concern is the effect of environmental factors that are beyond the influence of firms (observable heterogeneity) and factors that are not identifiable...

In den letzten Jahren wird vermehrt die Sorge geäußert, dass die Energiewende die Sicherheit der Stromversorgung in Deutschland langfristig durch Engpässe und Stromausfälle gefährden könnte. Während der Ausbau von volatiler Stromerzeugung aus Wind- und Sonnenenergie mit hohem Tempo...

The liberalisation of the Hungarian electricity and natural gas markets has been completed in 2009. The liberalisation of the electricity market resulted in different competitive positions in the production, the wholesale and the retail trade. The high level of market concentration survived in...

An electrical transmission network consists of producers, consumers and the power lines connecting them. We build an ideal (lossless) DC load flow model as a cooperative game over a graph with the producers and consumers located at the nodes, each described by a maximum supply or desired demand...

Wholesale electricity markets use different market designs to handle congestion in the transmission network. We compare nodal, zonal and discriminatory pricing in general networks with transmission constraints and loop flows. We conclude that in large games with many producers who are allowed to...

We review the recent empirical research concerning market power on the Nordic wholesale market for electricity, Nord Pool. There is no evidence of blatant and systematic exploitation of system level market power on Nord Pool. However, generation companies seem from time to time able to take...
