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...

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. <p> A detailed optimization model for European electricity markets is...</p>

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. <p>In this article we...</p>

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

Exposing wind and solar power to the market price signal allows for cost-efficient investment decisions, as it incentivizes investors to account for the marginal value (MV el) of renewable energy technologies. As shown by Lamont (2008), the MV el of wind and solar power units depends on their...

Renewable energy (RES-E) support schemes have to meet two requirements in order to lead to a costefficient renewable energy mix. First, RES-E support schemes need to expose RES-E producers to the price signal of the wholesale market, which incentivizes investors to account not only for the...

Electricity market models, implemented as dynamic programming problems, have been applied widely to identify possible pathways towards a cost-optimal and low carbon electricity system. However, the joint optimization of generation and transmission remains challenging, mainly due to the fact that...

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

Since PV grid parity has already been achieved in Germany, households are given an indirect financial incentive to invest in PV and battery storage capacities. This paper analyzes the economic consequences of the household's optimization behavior induced by the indirect financial incentive for...

Unter dem Merit-Order-Eekt (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 ist...
