When the supply of intermittent renewable energies like wind and solar is high, the electricity price is low. Conversely, prices are high when their supply is low. This reduces the pro t potential in renewable energies and, therefore, incentives to invest in renewable capacities. Nevertheless,...

We consider an economy in which competitive firms use three technologies for electricity production: pollutive fossils, intermittent renewables like wind or solar, and storage. We determine optimal subsidies for renewables and storage capacities when carbon pricing is imperfect. This policy is...

We consider an economy in which competitive firms use three technologies for electricity production: pollutive fossils, intermittent renewables whose availability varies continuously over time, and storage. A Pigouvian tax implements the first-best solution. This is also the case for an...

Steigende Anteile von fluktuierenden erneuerbaren Energien (EE) in Kombination mit technologischen Restriktionen konventioneller Kraftwerke verändern die Art und Weise, wie Elektrizität bepreist werden muss und somit das zugrunde liegende Strommarktdesign. Der Beitrag untersucht die...

Most electricity systems face contractual fixed consumer prices in the short term, that is, load and price are fixed before the random supply of renewables like wind or solar realizes. Steam power plants also make production decisions before such a random supply realizes. These capacities cannot...

Die Kosten von Technologien zur Nutzung fluktuierender erneuerbarer Energien (EE) wie Windturbinen und Photovoltaik-Anlagen sind in den vergangenen 15 Jahren enorm gefallen. Waren solche Technologien anfangs nur durch substanzielle Subventionen für Firmen wirtschaftlich anzuwenden, sind sie...

Increasing shares of intermittent renewable energies challenge the dominant way to trade electricity ex-ante in forward, day-ahead, and intraday markets: Coal power plants and consumers cannot react to the stochastic element of renewables, whereas gas turbines can. We use a theoretical model to...
