More than 150 municipal utilities (so-called Stadtwerke) were established in Germany from the beginning of the millennium, bringing the total number of Stadtwerke currently established within the country to approximately 900. With responsibility for more than half of the supply of electricity, gas and heat in Germany, these Stadtwerke play a central role in the transformation of the energy sector, or Energiewende. In addition, due to their local and regional ties, Stadtwerke have a particular role to play in energy politics, the economy and across society. This article focuses on the motives behind, and grounds for, the current wave of newly established Stadtwerke. Further, it discusses the factors that were critical to the successful formation of new Stadtwerke in recent years. The results of our survey indicate that the establishment of municipal Stadtwerke is a suitable measure to implement the energy transition at the local level, whereby the concept of public value has a high level of importance for the local decision-makers. Collaboration and cooperation, as well as a resilience-oriented strategy, are important success factors for new Stadtwerke.

In the light of Germany’s chosen path towards the energy transition, the regulatory framework has changed considerably. New players have succeeded in entering the market, and renewable energies have become increasingly competitive. Greater electrification of the transport and heating sectors will be needed in the future to achieve national climate targets. Against this background, Germany’s big energy companies need to be sure that their sales will increase. However, they were unable to anticipate this development, and made strategic mistakes in the past. The development of sustainable business models in line with the energy transition failed to materialize. Now it is becoming increasingly clear that companies must create new business models to survive in the long term. These business models have to keep with the tradition, whilst meeting the needs of low-carbon power supplies. In this paper, we will examine the past and future challenges of the four energy companies and develop a proposal for evaluating sustainable business models. For this purpose, we use the multi-level perspective to categorize developments in the electricity market over the last 50 years, and then apply a multi-criteria analysis to derive five suitable business models from the results.

Poor households in Germany and those that are close to the poverty line are more likely to suffer from increases in electricity costs. One consequence of this is the increasing number of cases in which the supplier disconnects a household's power. According to the Federal Network Agency (Bundesnetzagentur), a total of almost 359,000 interruptions of the electricity supply were caused in 2015 due to outstanding payments. In order to avoid disconnection from the electricity grid, more and more utility companies have begun to offer prepayment meters (PPMs) to their customers as a response to outstanding payments and a growing number of customers owing debts to their energy supplier. The phenomenon of an increasing number of households affected by energy poverty in Germany is new, and thus the number of PPMs is still low. As a result, experiences in this context are – compared to other countries (e.g. Great Britain) – far from extensive, and political awareness of the problem is low. This paper presents the findings of Germany's first scientific survey on experiences with the use of PPMs.

Energiearmut ist ein Phänomen, welches in Deutschland, wie auch in anderen Ländern des Globalen Nordens, in den letzten Jahren immer häufiger beobachtet werden kann. Zunehmend werden Prepaidzähler (engl. Prepayment Meter) von Energieunternehmen als Instrument eingesetzt, um KundInnen mit Zahlungsrückständen bzw. häufig auftretenden Zahlungsschwierigkeiten zu managen. Das Phänomen der Energiearmut in Deutschland ist relativ jung und damit die Anzahl der Prepaidzähler noch niedrig. Somit sind Erfahrungen in diesem Zusammenhang in Deutschland rar. Nachfolgend werden die Ergebnisse der ersten wissenschaftlichen Befragung von Haushalten mit Prepaidzählern in Deutschland (im Bundesland Nordrhein-Westfalen) analysiert. Dabei zeigt sich, dass Prepaid-Systeme für Strom für die betroffenen Haushalte mit erheblichen Alltagsveränderungen verbunden sind. Vorteilhaft ist, dass die Haushalte trotz bestehender Strom-Schulden weiterhin mit Energie versorgt werden können, dass sie über eine bessere Kostenkontrolle verfügen und dass sie Stromsparpotenziale erschließen können. Zu den wesentlichen Nachteilen zählen die hohen Kosten, der Aufwand für das Aufladen des Guthabens und dass Versorgungsunterbrechungen dennoch stattfinden, jedoch nicht erfasst werden. Insgesamt ergab die Studie eine hohe Zufriedenheit der Haushalte mit Prepaidzähler, es besteht jedoch Regulierungsbedarf seitens des Gesetzgebers in Deutschland.

After two decades of privatization and outsourcing being the dominant trends across public services, an inclination towards founding new municipal power utilities can be observed. In this article, the authors examine the preservation strategies of the German energy regime following the transition approach developed by Geels. From the multi-level perspective, it can be stated that innovations take place in niches and have to overcome the obstacles and persistence of the conventional fossil–nuclear energy regime. Through an empirical analysis, it can be concluded that the established regime significantly delays the decentralization process required for a transformation of energy structures on local electricity grids. Furthermore, it is shown that municipal utilities (Stadtwerke) are important key actors for the German Energiewende (energy transition) as they function as local energy distributors and they meet a variety of requirements to promote fundamental structural change. The trend towards re-municipalization and the re-establishment of municipal utilities reveal the desire to further strengthen the scope of local politics.
