The recent growth experimented by the Internet has fostered the interaction of many heterogeneous technologies under a common environment (i.e., the Internet of Things). Smart Grids entail a sound example of such situation where several devices from different vendors, running different protocols and policies, are integrated in order to reach a common goal: bring together energy delivery and smart services. Latest advances on this domain have led to effective architectures that support this idea from a technical perspective, but fail at providing powerful tools to assist this new business model. Hence, the purpose of this paper is to present a novel unified and ubiquitous management interface, driven by an intelligent system, that uses the advantages featured by the Web of Things to manage the Smart Grid. Therefore, this work opens a new path between the Internet of Things and the Web of Things resulting in a new concept coined as the Web of Energy.
