Die Auswirkungen des Atomausstiegs in Deutschland auf Strompreise und Klimaschutz in Deutschland und Europa

The German decision to phase-out nuclear energy and the impact of such a policy on electricity prices and the fulfillment of climate goals has been debated nationally as well as on European level. This study develops the expected effects by means of a European electricity market model and quantifies price developments, power plant investments, CO2 emissions and prices in different scenarios in...

Die Auswirkungen des Atomausstiegs in Deutschland auf Strompreise und Klimaschutz in Deutschland und Europa

Die Entscheidung zum Atomenergieausstieg hat in Deutschland und auch in Europa Diskussionen um die Wirkungen dieser Politik auf die Strompreise und die Einhaltung klimapolitischer Ziele ausgelöst. Die in diesem Projekt zu erarbeitende Studie untersucht die zu erwartenden Effekte mit Hilfe eines Europäischen Strommarktmodells. Dazu wird die Entwicklung der Strompreise, der Kraftwerksinvestitionen...

Balancing and Intraday Market Design: Options for Wind Integration

EU Member States increase deployment of intermittent renewable energy sources to deliver the 20% renewable target formulated in the European Renewables Directive of 2008. To incorporate these intermittent sources, a power market needs to be flexible enough to accommodate short-term forecasts and quick turn transactions. This flexibility is particularly valuable with respect to wind energy, where wind ...

Wind Power and Market Power in Competitive Markets

Average market prices for intermittent generation technologies are lower than for conventional generation. This has a technical reason but can be exaggerated in the presence of market power. When there is much wind smaller amounts of conventional generation technologies are required, and prices are lower, while at times of little wind prices are higher. This effect reflects the value of different generation ...

Regulated Expansion of Electricity Transmission Networks: The Effects of Fluctuating Demand and Wind Generation

We study the performance of different regulatory approaches for the expansion of electricity transmission networks in the light of realistic demand patterns and fluctuating wind power. In particular, we are interested in the relative performance of a combined merchant-regulatory mechanism compared to a cost-based and a merchant-like approach. In contrast to earlier research, we explicitly include both ...

Testing Regulatory Regimes for Power Transmission Expansion with Fluctuating Demand and Wind Generation

Adequate extension of electricity transmission networks is required for integrating fluctuating renewable energy sources, such as wind power, into electricity systems. We study the performance of different regulatory approaches for network expansion in the context of realistic demand patterns and fluctuating wind power. In particular, we are interested in the relative performance of a combined merchant-regulatory ...

Impact of Renewable Energy Act Reform on Wind Project Finance

The 2014 reform of the German Renewable Energy Act introduces a mandatory shift from a fixed feed-in tariff to a floating premium system. This is envisaged to create additional incentives for project developers, but also impacts revenues and costs for new investments in wind generation. Thus uncertainties for example about balancing costs and the impact of the location specific generation profile on ...

Comparison of Feed-in Tariffs and Tenders to Remunerate Solar Power Generation

This paper analyzes the trade-offs for using feed-in tariffs or tenders to remunerate different scales of solar photovoltaics (PV) projects. In recent years, European countries increasingly combined feed-in tariffs for small renewables systems with tenders for large installations. This study develops an analytic framework to quantify deployment effectiveness of responsive feed-in tariff adjustment ...

Integration von Wind- und Solarenergie: flexibles Stromsystem verringert Überschüsse

Die Umsetzung der Energiewende erfordert einen weiteren Ausbau von Windkraft und Photovoltaik in Deutschland. Die Stromerzeugungsmöglichkeiten beider Technologien schwanken stark je nach Wetterlage, Tages- und Jahreszeit. So kann es dazu kommen, dass temporär mehr Strom produziert wird, als zu diesem Zeitpunkt verbraucht werden kann. Das DIW Berlin hat anhand ausgewählter Zukunftsszenarien untersucht, ...
