There is an ongoing discussion about whether the German electricity market offers sufficient incentives for investment in power plants and for keeping them connected to the grid, thus ensuring sufficient security of supply. Recommendations for further securing power supply include payments, some...

Various capacity mechanisms are currently being discussed in Germany and beyond with a view to increasing supply security in the power sector. One of these mechanisms includes keeping a strategic reserve which means only using specific individual power plants in emergency situations when supply...

Der deutsche Atomausstieg in 2022 und die gleichzeitig stetig steigende Stromerzeugung durch fluktuierende Wind- und Sonnenenergie heizen in Deutschland, wie in Europa, seit geraumer Zeit eine Diskussion um die Versorgungssicherheitauf dem Strommarkt an. Dabei ist völlig unklar, wie...

Supply security in imperfect power markets is modelled under different market designs. In a uniform price auction for electricity with two firms, strategic behaviour may leave firms offering too few capacities and unable to supply all realized demand. Market design that relies on capacity...

Distributed energy resources allow for new business models that have the potential to substantially change today's power system functioning paradigm. In particular, these changes pose challenges for distribution system operators (DSOs) and their regulation alike. This article sheds light on...

We revisit key elements of European power market design with respect to both short term operation and longer-term investment and re-investment choices. For short term markets, the European policy debate focuses on the definition of common interfaces, like for example gate closure time. We argue...

With the European Strategic Energy Technology Plan (SET Plan) expiring in 2020, the EU needs to revisit its energy technology policy for the post-2020 horizon and to establish a policy framework that fosters the achievement of ambitious EU commitments for decarbonization by 2050. We discuss...

We examine welfare effects of real-time pricing in electricity markets. Before stochastic energy demand is known, competitive retailers contract with final consumers who exogenously do not have real-time meters. After demand is realized, two electricity generators compete in a uniform price...
