In this article we demonstrate how challenging greenhouse gas reduction targets of up to 95% until 2050 can be achieved in the German electricity sector.1 In the analysis, we focus on the main requirements to reach such challenging targets. To account for interdependencies between the...

In the aftermath of the nuclear catastrophe in Fukushima, German nuclear policy has been reconsidered. This paper demonstrates the economic effects of an accelerated nuclear phase-out on the German electricity generation sector. A detailed optimization model for European electricity markets is...

In this article we analyze the value of thermal energy storages in concentrating solar power plants depending on the electricity generation mix. To determine the value from a system integrated view we model the whole electricty generation market of the Iberian Peninsula. Key findings for thermal...

In this paper, the implications of alternative decarbonization pathways for Europe's power sector up until the year 2050 are analyzed. In specific, an electricity system optimization model is used to investigate the minimal costs of decarbonization under a stand-alone CO2 reduction target and to...

Electricity generation from renewable energy sources (RES-E) is supposed to increase significantly within the coming decades. However, uncertainty about the progress of necessary infrastructure investments, public acceptance and cost developments of renewable energies renders the achievement of...

As an attempt to fi ght global warming, many countries try to reduce CO2 emissions in the power sector by significantly increasing the proportion of renewable energies (RES-E). A highly intermeshed electricity transmission grid allows the achievement of this target cost-efficiently by enabling...

Renewable energies are meant to produce a large share of the future electricity demand. However, the availability of wind and solar power depends on local weather conditions and therefore weather characteristics must be considered when optimizing the future electricity mix. In this article we...

Unter dem Merit-Order-Effekt (M-O-E) der erneuerbaren Energien (EE) wird deren preissenkende Wirkung auf die Strompreise auf Großhandelsebene (Börsenpreise) verstanden. Sowohl die Höhe des Merit-Order-Effekts in der kurzen und der langen Frist als auch dessen volkswirtschaftliche Bedeutung...

In Europe, the availability of renewable energies, especially from sun and wind, differs significantly across regions. Consequently, cooperation in the deployment of renewable energy among European countries potentially yields substantial efficiency gains. However, in order to achieve the 2020...

This article analyses the flexibility of the German power market with respect to the integration of an increasing share of electricity from renewable energy sources. Flexibility limiting system components, which cause negative prices are explained and illustrated for the German market. Then, the...
