While the role of citizens in smart cities is hotly debated, there is a dearth of empirical research on the subject. This in-depth study of a European city, selected for its typical smart city ambitions, explores the roles that citizens actually play in smart city projects. The study examines twelve initiatives in the City of Utrecht (NL) using a framework that differentiates between types of citizen participation. The findings show that technology-enabled citizen participation in Utrecht is highly diverse and embraces all types of participation rather than simply taking the form of either ‘’citizen empowerment’’ (as the advocates argue) or ‘’citizen subjugation’ (as the critics stress). The diversity found in the study highlights the need to conceptualize the role of the smart citizen at the micro (project) level rather than at the level of the city as a whole. The study shows that citizen participation in the smart city should not be understood as a technological utopia or dystopia but as an evolving, technologically mediated practice that is shaped by a variety of factors.
