Potentiality of Self Sovereign Identities in Smart Grid

By applying the building theory from case study research by Kathleen M. Eisenhardt, this article describes a parsimonious and coherent process that puts into light as Self Sovereign Identity technology integrated into smart grids allows to give individuals back control of their energy data. First three research questions were defined. Next, significant cases studies were selected. Then the process moves forward by iteratively cycling through the case studies, developing theory, and cycling through white papers and existing literature articles until reaching the closure hence theoretical saturation. Through this process, focus of the article is delineating the potentialities and the challenges to face to integrate this cutting-edge technology in smart grid, highlighting as this technology allows to create a more reliable and transparent energy system. Results highlight for example as SSI paradigm ensures a high level of identity assurance for IoT devices within a grid, and allows users to maintain ultimate control over devices, hence over their energy data.
