The increased wind energy supplied to many electricity markets around the world has to be balanced by reliably ramping units or other complementary measures when wind conditions are low. At the same time wind energy impacts both, the utilization of thermal power plants and the market prices....

In order to compensate for fluctuations in electricity demand as well as electricity supply from renewables, power plants are required that are reliably available, even in critical situations. Besides an ongoing discussion whether the liberalized electricity market is capable of stimulating...

The German support for renewable energies in the electricity sector is based on the feed-in tariff for investors that grants guaranteed revenues for their renewable energy supply. Corresponding to differences of granted tariffs and respective market values, a surcharge on consumption covers...

The German decision to finally phase-out nuclear electricity has led to a debate on its effects on electricity prices, emission prices in the European emission trading system, as well as on international electricity trade. We investigate these effects with a Electricity market model for Europe...

Für den Ausgleich von Schwankungen der Stromnachfrage und des Stromangebotes aus erneuerbaren Energien sind Kraftwerke nötig, die auch in kritischen Situationen sicher zur Verfügung stehen. Es wird diskutiert, ob der liberalisierte Strommarkt in der Lage ist, ausreichende Investitionen...

In this paper, we use a computable general equilibrium model (WIATEC) to study the potential impact of implementing Europe's 20-20-20 climate policy. The results show that the economic costs of implementing the policy are only moderate and within the range of recent empirical evidence....

The German decision to finally phase-out nuclear electricity has led to a debate on its effects on electricity prices, emission prices in the European emission trading system, as well as on international electricity trade. We investigate these effects with a Electricity market model for Europe...

The increased wind energy supplied to many electricity markets around the world has to be balanced by reliable back up units or other complementary measures when wind conditions are low. At the same time wind energy impacts both, the utilization of thermal power plants and the market prices....

In diesem Wochenbericht wird der gegenwärtige Zustand des internationalen Rohölmarkts analysiert. Die Marktdaten deuten darauf hin, dass sich der Wettbewerb durch die mittlerweile fest etablierte US-Schieferölförderung dauerhaft intensiviert hat. Modellgestützte Simulationen zeigen zudem,...

In this study, we report on the current state of the international market for crude oil. The market data we analyzed indicate that competition has intensified as a result of the now firmly-established shale oil extraction industry in the U.S. Model-based simulations also show that supply-side...
