Abstract: The present invention relates to the provision of Energy consumption information with Virtual Energy Metering from Non-Energy metering data sources within Automation and Historian control systems. Through the use of a Virtual Energy Meter using an Energy Interface to communicate with various Automation or Historian control systems, devices such as motors and valves that do not have Energy monitoring functionality can provide Energy consumption information. The virtual energy meter converts Automation and Historian control data, such as device commands and feedback signals, into energy consumption information through the use of an energy translation method. The energy information is then made available for analysis through the virtual meters information data store. The advantage of the invention is that it removes numerous overheads associated with traditional energy metering such as the necessity for metering infrastructure, hardware, downtime and installation costs.
