In Germany and beyond, various capacity mechanisms are currently being discussed with a view to improving the security of electricity supply. One of these mechanisms is a strategic reserve that retains generation capacity for use in times of critical supply shortage. We argue that strategic reserves have specific advantages compared to other capacity mechanisms in the context of the European energy ...

In northern Europe, wind energy has become a dominate renewable energy source, due to natural conditions and national support schemes. However, the uncertainty about wind generation affects existing network infrastructure and power production planning of generators, which cannot be fully diminished by wind forecasts. In this paper we develop a stochastic electricity market model to analyze the impact ...

In this paper we analyze the effects of the German nuclear phase out, focusing on the seven nuclear power plants affected by the March 2011 moratorium, and continuing through the final phase out of the last plant in 2022. We provide an ex-post assessment of model analyses on the impact of the nuclear moratorium presented by the modelling community, in 2011 or shortly after. These are then compared ...

In the framework of the Energy Modeling Forum 28, we investigate how climate policy regimes affect market developments under different technology availabilities on the European power markets. We use the partial equilibrium model EMELIE-ESY with focus on electricity markets in order to determine how private investors optimize their generation capacity investment and operation over the horizon 2010 to ...

For the future development of the European electricity system, renewable generation is assigned a dominant role with the underlying aim to reduce the carbon intensity. This has direct implications for conventional, dispatchable generation capacities and their future development. The objective of this paper is to investigate the investments in conventional generation technologies for a given renewable ...

The management of congestion within the German transmission network has become more important during the last years. This emerging relevance is caused by the increase of renewable generation and the partial phase-out of nuclear power plants. Both developments yield a in the transmission flow pattern and henceforth the need for congestion management. Currently, four German transmission system operators ...
