The increasing share of electricity production from renewables is achieved by political promotion strategies like feed-in tariffs, which foresee payments for renewables outside of the electricity market. Assuming a phase out of the existing promotion strategies, the question arises if other or additional market design options for promoting low carbon technologies are necessary. In this paper, we have made an assessment based on the literature to identify possible market designs that are focusing on the promotion of low carbon technologies. The discussed options for altering the current market design range from providing greater certainty for future carbon prices, over capacity mechanisms for conventional as well as for renewable energy to a complete restructuring of the market design. The study shows that there seems to be three main tendencies to promote low carbon technologies, namely existing EOM with market add-ons for low carbon technologies, a separate market for low carbon technologies or an overall single market based on levelized ...

Legitimacy is a crucial factor determining the success of technologies in the early stages of development and for maintaining resource flows as well as public and political support across the technology life cycle. In sustainability transitions that unfold over long periods of time, the maintenance of legitimacy of technologies identified as vital for sustainability becomes a key challenge. In the energy sector, wind power contributes to the transition to an energy system with low greenhouse gas emissions. In Germany, wind power recently faced a series of lawsuits and decreasing investment activity. Therefore, we assess the legitimacy of wind power in Germany by analyzing newspaper articles from four national newspapers from 2009 to 2018. A large amount of articles motivates the use of topic models and statistical methods to shed light on the changing alignment of wind power with its context. The results show that various issues temporarily gain prominence on the agenda. Lately, the legitimacy of wind power in Germany is increasingly challenged by adverse effects on humans, animals, and landscapes. Policymakers and project developers may address aspects of pragmatic legitimacy, such as civic participation and the local distribution of profits.

In this article, cross-border effects of different market design options are analyzed using Switzerland, which is strongly interconnected to larger neighboring markets, as a case study. An investigation is conducted with an agent-based model where in one scenario, all market designs are represented according to the current legislation, and in another, energy-only markets (EOM) are assumed in all considered countries. The results show that wholesale electricity prices are highly dependent on the chosen market design and in the annual average are up to 27% higher in the EOM scenario. Due to expected larger interconnector capacities, this increase is evident in all simulated markets. Furthermore, the results indicate that the planned market design changes in the neighboring countries decrease investments in Switzerland. However, generation adequacy is still guaranteed due to the high Swiss hydropower storage capacity. Our results suggest that, under the current circumstances, a domestic mechanism in Switzerland is not required.

In dieser Studie werden die Effekte der Marktdesignänderungen der Nachbarländer auf den Schweizer Strommarkt und insbesondere auf die Wirtschaftlichkeit der Schweizer Wasserkraft untersucht. Hierfür wird in einem ersten Schritt ein ökonometrisches Modell basierend auf einer multiplen linearen Re-gression erstellt, um die Treiber der Schweizer Strompreise am Elektrizitätsgroßhandelsmarkt zu be-stimmen. Die Ergebnisse deuten darauf hin, dass die französische Last und der Schweizer Großhan-delsstrompreis in Spitzenlastzeiten aufgrund der Strommarktkopplung stark zusammenwirken. Dar-über hinaus werden starke Korrelationen zwischen den Großhandelsstrompreisen in Deutschland, Frankreich und der Schweiz im Frühjahr und Sommer beobachtet. Außerdem haben die deutsche Windkraft- und die Photovoltaik-Stromerzeugung im Frühjahr und im Sommer einen negativen Einfluss auf die Schweizer Großhandelsstrompreise, der jedoch im Laufe des Herbsts und Winters abnimmt. Im Winter folgen die Schweizer Großhandelsstrompreise vor allem den italienischen und den französi-schen Großhandelspreisen. Ferner werden mit einem agentenbasierten Simulationsmodel (PowerACE) energiewirtschaftliche Sze-narien bezüglich der Entwicklung des Strommarktes untersucht. Im ersten Szenario werden alle Markt-designs (implementierte Kapazitätsmechanismen) so gewählt, wie sie zum Zeitpunkt der Erstellung der Studie den politischen Gegebenheiten entsprachen. Als zweites Szenario wird in allen umliegenden Ländern der Schweiz (Deutschland, Frankreich, Italien sowie Österreich) ein sogenannter Energy-only-Markt angenommen. In beiden Szenarien werden insbesondere die Entwicklung der Großhandelss-trompreise und der Kraftwerkskapazität untersucht. Auch die Ergebnisse des agentenbasierten Mo-dells verdeutlichen, dass eine starke Abhängigkeit der Großhandelsstrompreise von den Entwicklun-gen in den Nachbarländern, unabhängig vom gewählten Szenario, besteht oder sogar durch den Aus-bau der Handelskapazitäten noch zunimmt. Hinsichtlich der Kraftwerkskapazitäten ergeben ...
