Abstract

An electrical outlet, an electrical outlet cover for use with an electrical outlet and methods of identifying a grid connection point for bill processing of a charging event and managing energy services are disclosed. The electrical outlet cover includes a cover unit having a receptacle opening configured to align with a receptacle of the electric outlet and an identification unit configured to present a unique identification that is associated with the electrical outlet. In an embodiment, a method includes establishing an identity tag at a grid connection point (GCP) that unique identifies the GCP, receiving identity tag information to uniquely identify the GCP and monitoring charge event information indicating attributes of the charging event. The method further includes associating the charge event information with the identity tag information, as associated information; and sending the associated information for reconciliation of billing accounts associated with the GCP and the mobile charging device.
