Claim:
1. A method for determining energy power savings for a load under certain weather conditions comprising: determining, by a load controller operating at an end user location, that a load is running in a predetermined manner, the load controller being operatively connected to both the load and to power transmission lines by which power from a power distribution system of a power utility is supplied to the load; repeatedly measuring, by the load controller, energy usage of the load; determining, by a demand response load control (DRLC) determination controller associated with the power distribution system, that, by predictive analysis based on current weather forecast data obtained at time intervals during a day, historical statistical power consumption data associated with the load for past weather conditions and related to the current weather forecast data for corresponding time intervals, and current power usage information, that either a power savings mode or a DRLC event should be initiated, the DRLC determination controller, upon reaching said determination of a power savings mode or DRLC event, notifying the load controller for the end user location; the load controller for the end user location, upon receiving said notification, modifying operation of the load by modifying the load's cycle of operation if the load is in operation, delaying a start in the load's operation if the load is not already in operation, once the load is in operation if the load is allowed to operate or, if the load is already in operation, changing a set point which would allow the load to otherwise draw more power, and including performing all of these actions, thereby reducing a power draw of the load so the load consumes less power than if there were no power saving mode or DRLC event; the DRLC determination controller, upon determining that said power saving mode or DRLC event is over, notifying the load controller for the end user location; calculating, by the load controller, a resultant energy savings by comparing measured energy usage by the load during the power savings mode or DRLC event with energy usage statistics for power consumption of the load when no power saving mode or DRLC event had occurred during a period of similar weather forecast conditions for corresponding time intervals; and transmitting by the load controller the calculated energy savings over a communications link to the power utility.
