A facility comprising systems, methods, and techniques for collecting data indicative of energy consumption and/or energy production by energy systems and devices and providing the data to interested users and devices in real-time is described. The facility may comprise an energy gateway device coupled to one or more monitored devices, one or more energy data extraction servers, and one or more client computers. The energy gateway devices and energy data extraction servers are coupled to a network and are configured to collect energy consumption and/or energy production data from one or more devices and provide an indication of the collected data in real-time or near real-time. The facility may collect current energy consumption or production rates, predicted energy consumption or production levels over a future period of time, and/or amounts of energy that has been consumed or produced by the device over a previous period of time.
