Automated demand response has the potential to be an essential future tool for maintaining the balance of supply and demand in electrical energy systems with a very high density of generation from renewable sources. Although this scenario can become true in the near future, only very few actual implementations of automated demand response can be found in Europe. This paper is tackling this by analyzing current demand response implementations, placing them into a matrix of different aspects and strategies, with the goal to provide a systematical basis of current application scenarios of demand response, highlighting barriers and starting points for further development decisions. Recommendations for important and possible near future application scenarios of demand side energy management concepts in Austria are the result of this analysis by a multidisciplinary team of researchers. This paper describes related and important future work for Austria in demand response in context of a defined scenario kit. Aspects and strategies of each scenario are described in the following subsections.

ZusammenfassungAutomatisiertes Lastmanagement hat das Potenzial, in einem zukünftigen, mit Kommunikationsinfrastruktur ausgestattetem Stromnetz durch Verschiebung von elektrischen Lasten trotz einer hohen Dichte an erneuerbarer Erzeugung die Leistungsbalance zu gewährleisten. Dieses Paper stellt eine systematische Herangehensweise vor, die eine umfassende Bewertung und Weiterentwicklung von Lastmanagement-Szenarien ermöglicht. Es wird ein neuer Ansatz zur Integration der Entwicklung und Bewertung solcher Szenarien vorgestellt und vier erfolgsversprechende Modelle von Komponenten zukünftiger elektrischer Energieversorgungssysteme eingehender analysiert. Das Problem fehlender Umsetzungen wird anhand dieser Szenarien beispielhaft für Österreich durch eine interdisziplinäre Betrachtung des Phänomens Lastmanagement hinsichtlich technischer, sozialer, ökonomischer und ökologischer Aspekte untersucht. Ergebnis dieser Betrachtung sind neben Analyseergebnissen eine Bewertung der Szenarien und die daraus gewonnenen Empfehlungen für neue Rahmensetzer und die Forschungsförderung.

Discussions on the role of participatory approaches in technology assessment and technology policy have a long history. While in the beginning this subject was handled mainly as a theoretical requirement for democratic governance of technology, active involvement of stakeholders and laypeople became popular in TA exercises throughout the 1980s. Since then, a variety of participatory TA (pTA) methods and strategies have been developed and widely used, raising further far-reaching expectations. It has been argued that participatory approaches might broaden and hence enrich the knowledge and value base in ongoing technological discourses and eventually improve the factual as well as democratic legitimacy of technology-related decisions (Joss and Bellucci 2002). Moreover, a stronger integration of diverse actors and stakeholders was linked to the promise of better socially embedded solutions, an increased acceptance and enhanced diffusion of technology as well as technology policy. However, practical experiences with pTA have shown that under real-world conditions, it is difficult to meet all these expectations (e.g. Abels and Bora 2004). Despite a continuing and widespread interest in pTA, empirical evidence and theoretical positions on the practical performance of pTA have remained ambiguous.

Das Telefon, der Personalcomputer, danische Windrader – diese drei Technologien haben eines gemeinsam: sie sind weltweit erfolgreich. Und es gibt noch eine weitere – vielleicht etwas uberraschende – Gemeinsamkeit. In allen drei Fallen lieferten Nutzer/-innen in fruhen Entwicklungsphasen wertvolle Impulse, ja zum Teil lag die technische Entwicklung fast zur Ganze in der Hand von Nutzer/-innen. Auch in jungster Zeit fliegen die Erwartungen an den Beitrag von Nutzer/-innen zu neuen Produkten und Technologien hoch. Vor allem der Einfluss von Informationsund Kommunikationstechnologien und des Internet eroffnen hier neue Moglichkeiten: Open Source Software ermoglicht die Verteilung von Entwicklungsleistungen fur neue Programme auf eine Vielzahl von Beteiligten, die meist auch selbst ein Nutzungsinteresse an diesen Produkten haben; entsprechende Software-Tools und Plattformen ermoglichen die Entwicklung neuer Computerspiele und anderer Produkte durch User-Communities; und auch der Trend bzw. die technischen Moglichkeiten fur ‚mass customization‘ machen Nutzer/-innen in gewissem Sinn zu Mitproduzent/-innen ihrer masgefertigten Endprodukte. Eric von Hippel (2005) geht in seinem vor einigen Jahren erschienen Buch sogar so weit, dass er von einer „Demokratisierung des Innovationsprozesses“ spricht. Schone neue Nutzer-Welt?

In Austria, the highest potential for sustainable refurbishment is within the sector of single-family houses, which were built between 1945 and 1980. According to estimates, two-thirds of all the possible investments can be assigned to this category. However, there are only a few ambitious models on the supply side, which combine the efficient information and mobilisation of users with a comprehensive technical and ecological offer. Two of these rare examples will be discussed in this paper. Both models have been operating at a local level for the promotion of sustainable refurbishment for several years. The studied examples are characterised by network structures that are constituted by heterogeneous local social players who aim at quality assurance to enable attractive offers for homeowners. Centrally coordinated units manage both network models. In addition to the management of networks, these units try to fulfil several other functions: public relations, training seminars, strategic development, advisory services for end users and the implementation of refurbishment measures. Based on a comprehensive analysis and documentation of both models, we will present a critical evaluation of the network activities. It becomes clear that both examples face two major challenges: internally, to cover and productively manage a wide range of different functions in order to stimulate necessary innovations and externally, to influence the sociopolitical framework conditions to increase the demand for noticeable sustainable refurbishment.

Der Klimawandel weist neue Problemqualitaten wie Globalitat, Ursache-Wirkungsentkoppelung, Dringlichkeit, Unsicherheit und Komplexitat auf, die nicht nur die Wissenschaft sondern auch die Politik vor grose Herausforderungen stellen. Vor diesem Hintergrund gewinnen weltweite Verhandlungsprozesse an Bedeutung, denn globale Herausforderungen erfordern globales Entscheiden. Dies bedeutet auch die Entwicklung neuer Kommunikationsstrategien, Meinungsbildungsverfahren und Entscheidungswege, wozu das Projekt World Wide Views on Global Warming (kurz: WWViews) einen Beitrag geleistet hat.

This paper reports on experiences using a participative technology assessment (pTA) approach to discuss and evaluate research and development goals for sustainable energy technology in Austria. In a two-day Future Search & Assessment conference in November 2007, 36 per representative quota selected laypeople discussed the future of energy research in Austria on two different levels: general visions of sustainability as well as deduced short-term aspects regarding the present end-user related energy research agenda. The strategy chosen consists of a well-balanced mix of focus groups, plenary sessions, expert inputs, and moderated working groups. The five topics discussed in the laypeople’s conference were: micro combined heat and power (micro-CHP), new system solutions and avoidance strategies, smart metering and ‘intelligent’ end user equipment, innovative contracting and leasing models, and visualization and monitoring devices. We aim to show that pTA can contribute twofold to technical innovation: Firstly, it can contribute to the social robustness of the underlying strategies and scenarios of relevant research programmes; and secondly, the research topics that directly refer to the end-users can be critically evaluated in terms of social acceptability and user friendliness. Moreover the chosen approach serves as a platform to discuss long-term energy policies as well as practical consequences.
