NOVELTY - The method involves detecting connection of a portable device (408) associated with an energy-consumption based incentive (410) to a power grid through a smart meter (404). The energy-consumption based incentive is provided to an address associated with the smart meter. Connection of the device is detected to the power grid through another smart meter (412). The energy-consumption based incentive is provided to another address associated with the latter smart meter. A device identifier is determined through wireless or wired communication between the device and the former smart meter.    USE - Method for providing an energy-consumption based financial incentive e.g. on-note financing or periodic utility note reduction or periodically applied rebate, to a consumer for encouraged program e.g. energy-efficient upgrade and purchase. Can also be used for an up-front price reduction incentive and periodic repayment of up-front financing incentive.    ADVANTAGE - The method enables detecting connection of the portable device (408) associated with the energy-consumption based incentive to the power grid through another smart meter and providing the energy-consumption based incentive is provided to another address associated with the latter smart meter to improve an efficiency of appliances and the device.    DETAILED DESCRIPTION - The device is selected from a group consisting of a monitoring device, an electronic device, an appliance, a heating/ventilation/air conditioning (HVAC) device, an electric car, a solar power generation device and a car charging device. INDEPENDENT CLAIMS are also included for the following:    (1) a power utility manager for providing an energy-consumption based incentive    (2) an energy-consumption based incentive manager for managing incentives for power utilities    (3) a computer-readable storage device comprising a set of instructions for providing energy-consumption based incentive.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram illustrating a method for employing a smart meter to monitor a consumer appliance and apply incentive associated with the consumer appliance transported to a new-location.
