"Generating electricity from renewable sources is more expensive than conventional approaches, but reduces pollution externalities. Analyzing the tradeoff is much more challenging than often presumed, because the value of electricity is extremely dependent on the time and location at which it is...

In der Stromversorgung vollzieht sich seit etwa zwanzig Jahren ein grundlegender Wandel von konventioneller Stromerzeugung durch hauptsächlich Kohle- und Atomkraftwerke hin zu erneuerbaren Stromerzeugung durch hauptsächlich Windkraft- und Solaranlagen. Die Hauptunterschiede zwischen diesen...

The diffusion of renewable energy in the power system implies high supply variability. Lacking economically viable storage options, renewable energy integration has so far been possible thanks to the presence of fast-reacting mid-merit fossil-based technologies, which act as back-up capacity....

The emerging literature on power markets with high shares of fluctuating renewables suggests that more frequent start-up procedures of thermal power plants may become an increasing concern, both for costs and possibly also for market design. Based on official scenario assumptions, we investigate...
