The smart grid as commons: exploring alternatives to infrastructure financialisation

This paper explores a tension between financialisation of electricity infrastructures and efforts to bring critical urban systems into common ownership. Focusing on the emerging landscape of electricity regulation and e-mobility in the United Kingdom (UK), it examines how electricity grid ownership has become financialised, and why the economic assumptions that enabled this financialisation are being called into question. New technologies, such as smart electricity meters and electric vehicles, provide cities with new tools to tackle poor air quality and greenhouse gas emissions. Electricity grids are key enabling infrastructures but the companies that run them do not get rewarded for improving air quality or tackling climate change. UK government regulation of electricity grids both enables financialisation and forecloses opportunities to manage the infrastructure for wider environmental and public benefit. Nonetheless, the addition of smart devices to this network - the ‘smart grid’ – opens up an opportunity for common ownership of the infrastructure. Transforming the smart grid into commons necessitates deep structural reform to the entire architecture of infrastructure regulation in the UK

Long-term research challenges in wind energy – a research agenda by the European Academy of Wind Energy

The European Academy of Wind Energy (eawe), representing universities and institutes with a significant wind energy programme in 14 countries, has discussed the long-term research challenges in wind energy. In contrast to research agendas addressing short- to medium-term research activities, this eawe document takes a longer-term perspective, addressing the scientific knowledge base that is required to develop wind energy beyond the applications of today and tomorrow. In other words, this long-term research agenda is driven by problems and curiosity, addressing basic research and fundamental knowledge in 11 research areas, ranging from physics and design to environmental and societal aspects. Because of the very nature of this initiative, this document does not intend to be permanent or complete. It shows the vision of the experts of the eawe, but other views may be possible. We sincerely hope that it will spur an even more intensive discussion worldwide within the wind energy community

Toward a polycentric low-carbon transition: the roles of community-based energy initiatives in enhancing the resilience of energy systems

An understanding of the resilience of energy systems is critical in order to tackle forthcoming challenges. This chapter proposes that the polycentric governance perspective, developed by Vincent and Elinor Ostrom, may be highly relevant in formulating policies to enhance the resilience of future energy systems. Polycentric governance systems involve the coexistence of many self-organized centers of decision making at multiple levels that are formally independent of each other, but operate under an overarching set of rules. Given this polycentric approach, this chapter studies the roles of community-based energy initiatives and, in particular, of renewable energy cooperatives, in enhancing the institutional resilience of energy systems. In this perspective, the chapter identifies three major socio-institutional obstacles, which undermine this resilience capacity: the collective action problem arising from the diffusion of sustainable energy technologies and practices, the lack of public trust in established energy actors and the existence of strong vested interests in favor of the status quo. Then, it shows why the development of community-based energy initiatives and renewable energy cooperatives may offer effective responses to these obstacles, relying on many empirical illustrations. More specifically, it is argued that community-based energy initiatives present institutional features encouraging the activation of social norms and a high trust capital, therefore enabling them to offer effective solutions to avoid free riding and enhance trust in energy institutions and organizations. The creation of federated polycentric structures may also offer a partial response to the existence of vested interests in favor of the status quo. Finally, some recommendations for policymakers are derived from this analysis

Selection of variables using 'independence Bayes' in computer-aided diagnosis of upper gastrointestinal bleeding

In this paper two problems of computer-aided diagnosis with 'independence Bayes' were investigated: selection of variables and monotonicity in performance as the number of measurements is increased. Using prospective data from patients with upper gastrointestinal bleeding, the stepwise forward selection approach maximizing the apparent diagnostic accuracy was analysed with respect to different kinds of bias in estimation of the true diagnostic accuracy and to the stability of the number and type of variables selected. The results of this study suggest first that the selection of variables should be evaluated against the estimated true diagnostic accuracy obtained using all variables, and secondly that the results of a single selected sequence may be severely biased

Aligning modes of organization with technology: Critical transactions in the reform of infrastructures

We address the alignment of technology and modes of organization in infrastructures in the context of their reform. Since infrastructures are characterized by strong technical complementarities, we explore the resulting ‘critical technical functions that need to be performed in order to guarantee the expected technical performance of the system. We characterize ‘critical transactions’ as essential to provide adequate support to these functions. We distinguish various modes of organization that can effectively coordinate these critical transactions. We argue that the features of these transactions determine the alignment between organization and technology and should be taken explicitly into account when reforming infrastructures.Infrastructures, Systems and ServicesTechnology, Policy and Managemen

Internationalization of Infrastructures: Proceedings of the 12th Annual International Conference on the Economics of Infrastructures

What are the economic effects of the internationalization of infrastructures? We have addressed this question at the 12th Annual International Conference on the Economics of Infrastructures (Delft, May 2009). Internationalization of infrastructures refers to the increasing network interconnections of infrastructures across borders, and, as a consequence, the creation of international organization to operate them, and the development of international institutions to govern them. These proceedings compiles contributions on the industrial sectors of oil and gas, electricity, telecommunications, water and railways. In addition, they include a section on the history and another on future perspectives of the internationalization of infrastructures.Infrastructure Systems & ServicesTechnology, Policy and Managemen
