Potenziale zur Erhöhung des regionalen Markenkerns im Stromvertrieb am Beispiel der regionalen Grünstromkennzeichnung gemäß EEG 2017: Teil 2 (Multikriterien-Analyse)

In this paper – complementing an earlier article on this topic (Part 1: Basics and Analysis of Potentials) – we perform a Multicriteria Decision Analysis (MCDA), also engaging decision-makers in the analytical process. From the MCDA we derive recommendations to act with regard to the alternatives for regional green power marketing (cf. Part 1). For the MCDA we have developed a hybrid multicriteria approach, which enables to pool the advantages of two methods. Specifically, for the valuation of alternatives and criteria weighting we use the so-called Multi-Attribute Global Inference of Quality (MAGIQ) method, whereas the computation of the analytical results was performed with the help of an optimized Weighted Aggregated Sum Product Assessment (WASPAS) method. The results of the MCDA show that the regional green power labeling according to EEG 2017 can be used for upgrading the options already existing before the introduction of the EEG 2017 for the marketing of regionally generated electricity. From the MCDA conducted we find that those green power marketing models which combine the regional green power labeling according to the EEG 2017 with previously existing options rank first to third.     

Ein Jahr danach: Erste empirische Ergebnisse der Ausschreibungen für Windenergie an Land gemäß EEG 2017

The sixth amendment of the German Renewable Energy Sources Act (Erneuerbare-Energien-Gesetzes [EEG]) came into force at January 1st, 2017. Especially regarding onshore wind energy, it includes fundamental changes. Having set raised market integration as well as market compatibility and cost-efficiency as the main three goals, market-based tendering shall be the instrument to reach them.Meanwhile, the first three calls have been completed. This enables the opportunity for a first evaluation of the tendering as a system to fund onshore wind energy in Germany and a comparison of the criticism which came along with the newest amendment. At first glance, several improvements can be found: Especially a—previously expected—forced competition on the market but also low bid and tender values show a massive potential of cost reduction. However, the analysis further shows that energy cooperatives are disproportionally privileged, which leads to a distortion of competition and the risk of a future non-continuous development. Additionally, the current system results in regional disparities, coming along with disadvantages especially for the southern states. 10 suggestions for improvement show possible answers concerning the main shortcomings.     

Die Kosten des Klimaschutzes am Beispiel der Strompreise für private Haushalte

Power prices in Germany have been surging since the outset of the new millennium. Among the major reasons for this tendency are newly raised taxes and levies on electricity prices, whose introduction is primarily motivated by climate concerns. Without these taxes and levies, net electricity prices would have remained constant for private households. This article discusses these taxes and levies that have been responsible for the cost increases in private households’ electricity consumption. Most influential have been the feed-in tariffs for renewable energies, above all photovoltaics. According to our calculations, the levy for renewables will further increase in the up-coming years, thereby pushing consumers’ electricity cost once again. Our calculations also show that within the next couple of years, there will be a fierce competition among renewable energy technologies, most notably between photovoltaics and wind power. Politics would be well-advised, therefore, to limit the annual capacity of newly installed solar modules in order to avoid both the explosion of consumers’ electricity bills and strong competition among renewables.     

Und Aktion! – Konzeptualisierung der Rolle individuellen Akteurshandelns in sozio-technischen Transitionen am Beispiel der regionalen Energiewende im bayerischen Allgäu

The German “Energiewende” is one of the most ambitious societal transition projects in recent times. It causes fundamental political and economic changes in the energy system in Germany and the whole of Europe. These great societal and technological changes of the current energy regime are of particular interest for research on sustainability transitions. In this research strand, however, the role of individual agency for socio-technical transitions is hardly considered. What drives actors who decisively pushed the regional energy transition? Which strategies and types of action do they choose to foster the transition? How do individual strategies and actions depend on the socio-technical system environment and how does the socio-technical system environment react to the individual actions? To analyse these questions, we apply the Human-Environment Systems (HES) Framework (Scholz, 2011) for the first time to socio-technical systems. Based on an exemplary analysis of the regional energy transition in the Allgäu region in Germany, we propose an adaptation of the HES Framework for socio-technical systems. Finally, we reflect on how the adapted HES framework for socio-technical systems can contribute to a better understanding of individual agency in systemic transitions.
