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 ...

Carbon Markets and Technological Innovation

This paper examines the effects of firm-level innovation in carbon-abatement technologies on optimal cap-and-trade schemes with and without price controls. We characterize optimal cap-and-trade regulation with a price cap and a price floor, and compare it to the special cases of pure taxation and a simple emissions cap. Innovation shifts the tradeoff between price- and quantity-based instruments towards ...

Understanding the Roles and Interactions of International Cooperation on Domestic Climate Policies: Editorial

Introduction: The United Nations Framework Convention on Climate Change defines the principle of common but differentiated responsibility (Art. 4.1 of UNFCCC). It is the common responsibility of all countries to pursue mitigation actions so as to achieve climate stabilization. The differentiated nature of historic responsibility, capabilities and economic situation creates a responsibility for developed ...

Policy Targets: Lessons for Effective Implementation of Climate Actions

Policy targets are used to improve the implementation of domestic and international actions, in a national context and in international frameworks. But how can domestic and international experience be useful for climate policy? Case studies point to the value of defining policy targets more broadly than final outcomes, which in the case of climate policy are CO2 emission reductions. There is a need ...

A History of Conditionality: Lessons for International Cooperation on Climate Policy

This article surveys the experience of conditionality provisions applied by the World Bank, the IMF, bilateral donors, and the European Union's accession process. Ownership is essential for effective cooperation and requires domestic climate policies to be country-driven and decision-making to be equitable. Bilateral cooperation allows for a direct exchange of expertise and long-term relationships. ...

A Comparison of Electricity Market Designs in Networks

In Europe, two market designs are discussed for electricity trade and transmission. We argue that their performance in the presence of market power can be represented by two models from the literature. In contrast to examples for simple two-node networks, we show that in more complex networks a general ranking of both designs is not possible. Hence, computational models are required to evaluate the ...

Commitments through Financial Options: An Alternative for Delivering Climate Change Obligations

Governments willing to commit themselves to maintain carbon prices at or above a certain level face the challenge that their commitments need to be credible both for investors in low-carbon technology and for foreign governments. This article argues that governments can make such commitments by issuing long-term put option contracts on the price of CO2 allowances. This mechanism gives investors the ...

Germany and Poland in the Energy Union: Moving from Controversies to Shared Interests?

Klimaschutzpolitik: Wie kann ein Politikmix gestaltet werden?

Zum Schutz des Klimas ergreift die Politik in Deutschland und Europa eine Vielzahl an Maßnahmen. So wird der europäische Emissionshandel durch zahlreiche Maßnahmen zur Innovations- und Investitionsförderung ergänzt, aber auch durch Informationsbereitstellung und Regulierungsmaßnahmen zur Nutzung neuer Technologien. Dieser Politikmix wirft die Frage auf, welche Politikinstrumente benötigt werden und ...

Distributional Effects of Energy Transition: Impacts of Renewable Electricity Support in Germany

The discussion of the support for renewable energy must consider the distributional impact of cost allocation. The public is sensitive to social imbalances caused by rising power prices that might jeopardize the acceptance of energy transformation. By the end of 2012 about 19 percent of German power is produced with renewables other than hydropower. As a result, German consumers will pay for global ...
