The energy transition has highlighted the need for consumer engagement to visualize the future power grids known as smart grids. However, the dynamics of consumer engagement in smart grids remain poorly understood, particularly in the context of the increasing role of smart service providers. Smart service providers digitalize how consumers engage with smart grids by leveraging smart technologies to provide services for consumers. Since smart services complicate the understanding of consumer engagement, especially by automating the service functionalities, this licentiate thesis aims to explore the role of smart service providers in digitalizing consumer engagement within smart grids. Adopting a case study as the research strategy, this qualitative and interpretive thesis investigates two service providers in Sweden as case organizations. Using interviews, observation, tweet analysis, documents, and literature review, this thesis answers three questions to shed light on the characteristics of smart technologies, smart service providers’ actions to enhance the potential for engagement, and challenges of engaging consumers from the perspective of smart service providers. In conclusion, this thesis depicts that digitalizing consumer engagement incorporates different initiatives taken by service providers besides characteristics of smart technologies that facilitate the provision of services. Moreover, this thesis suggests a definition of digitalized consumer engagement based on two aspects of delegation and supervision since service providers encourage consumers to configure and monitor smart services through provided technologies. The practical contributions of this thesis provide insights for smart service providers on designing smart technologies and strategies that enhance the potential for consumer engagement. The theoretical contributions extend the understanding of consumer engagement by framing it as a dynamic, co-constructed process influenced by the sociotechnical roles of service providers and the delegation of tasks to smart technologies.
