A power device discovery and visualization system identifies and categorizes smart power and energy devices deployed within an industrial enterprise, and generates interfaces that render customized presentations of a plant's power and energy usage based on data retrieved from the discovered devices. The system also facilitates remote configuration of the discovered smart devices via interaction with a single consolidated interface that affords access to all discovered power and energy devices. The system constructs a device profile for each discovered smart device based on information retrieved from the device, and categorizes each discovered device according to device type (e.g., power meter, IED, VFD, controller, etc.). The system retrieves available historical, real-time, and/or configuration data from each discovered smart device and makes this data available for viewing or modification via the system interface, thereby unifying plantwide power and energy data into a common presentation.
