20090062970 | System and method for active power load management - A system for managing consumption of power supplied by an electric utility to power consuming devices includes at least one client device and a server. Each client device operates at least partially responsive to control messages received from the server and controls operation of one or more controllable devices. Each controllable device selectively enables and disables a flow of power to one or more of the consuming devices. The server stores information, on a per client device basis, relating to power consumed by the consuming devices. When a power reduction is requested by the utility, the server selects, based on client device information stored in the database, at least one client device to which to issue a power reduction message that indicates at least one of an amount of power to be reduced and an identification of a controllable device to be instructed to disable a flow of power. | 03-05-2009 |
20090063228 | Method and apparatus for providing a virtual electric utility - A method and apparatus for virtually generating electricity for use by electric utilities provide a virtual electric utility. In one embodiment, a non-power generating electric utility enters into a supply agreement to acquire electric power from an electric power generating entity. During a term of the agreement, the non-power generating utility intentionally refrains from receiving at least some of the electric power to which it is entitled under the agreement to produce deferred electric power. The non-power generating utility offers to supply the deferred electric power to third party, such as an electric power supplier or an electric power consumer. The power deferment is preferably achieved through issuance of power control commands to a load management system. In another embodiment, an independent third party controls the load management system to function as an alternative energy supplier by virtually supplying deferred electric power back to a power grid. | 03-05-2009 |
20100145534 | SYSTEM AND METHOD FOR DETERMINING AND UTILIZING CUSTOMER ENERGY PROFILES FOR LOAD CONTROL FOR INDIVIDUAL STRUCTURES, DEVICES, AND AGGREGATION OF SAME - A system and method for creating and making use of customer profiles, including energy consumption patterns. Devices within a service point, using the active load director, may be subject to control events, often based on customer preferences. These control events cause the service point to use less power. Data associated with these control events, as well as related environment data, are used to create an energy consumption profile for each service point. This can be used by the utility to determine which service points are the best targets for energy consumption. In addition, an intelligent load rotation algorithm determines how to prevent the same service points from being picked first each time the utility wants to conserve power. | 06-10-2010 |

20100191862 | SYSTEM AND METHOD FOR PRIORITY DELIVERY OF LOAD MANAGEMENT MESSAGES ON IP-BASED NETWORKS - Methods for prioritizing load management messages on IP-based networks utilizing an Active Load Directory and IP capable two-way gateway. The messages being received from, or sent to, the ISP through the gateway contain a blend of regulated and unregulated data. The regulated data is high-priority utility load management data such as, equipment status and load control instructions. The unregulated data consists of Internet messages such as email and web site data. These methods process all regulatory data before unregulated data within strict time limits, providing the greatest possible load management control and energy savings. The methods emulate dedicated network processor memory in a manner that permits the rules for prioritizing, scheduling, and routing to remain the same across both hardware and software implementations. | 07-29-2010 |

Control event actions are carried out to limit power usage within preferences set by the customer. | 08-05-2010 |
20100222935 | SYSTEM AND METHOD FOR ESTIMATING AND PROVIDING DISPATCHABLE OPERATING RESERVE ENERGY CAPACITY THROUGH USE OF ACTIVE LOAD MANAGEMENT - A utility employs a method for estimating available operating reserve. Electric power consumption by at least one device serviced by the utility is determined during at least one period of time to produce power consumption data. The power consumption data is stored in a repository. A determination is made that a control event is to occur during which power is to be reduced to one or more devices. Prior to the control event and under an assumption that it is not to occur, power consumption behavior expected of the device(s) is estimated for a time period during which the control event is expected to occur based on the stored power consumption data. Additionally, prior to the control event, projected energy savings resulting from the control event are determined based on the devices' estimated power consumption behavior. An amount of available operating reserve is determined based on the projected energy savings. | 09-02-2010 |

The controller is located remotely from the service point(s) and determines power consumed over time by at least one device located at the service point(s) to produce power consumption data. The controller stores the power consumption data. At some later point in time, the controller initiates a control event and determines an amount of power reduced during the control event based on the stored power consumption data. The controller also determines a generation mix for power that would have been supplied to the service point(s) if the control event had not occurred. The controller then determines a quantity of carbon credits earned based at least on the amount of power reduced and the generation mix. | 09-16-2010 |
20110022239 | METHOD AND APPARATUS FOR EFFECTING CONTROLLED RESTART OF ELECTRICAL SERVCIE WITH A UTILITY SERVICE AREA - An active load management system (ALMS) controllably restarts electrical service to service points in a utility service area after a power outage. The ALMS includes client devices installed at the service points and a central controller. In one embodiment, the controller associates numbers with the service points and stores the associations. Each service point may be associated with a unique number or a group of service points may share a number. After receiving notification that power is available, the controller determines a number and communicates the number to one or more of the client devices. Where the number was determined randomly, the client devices associated with the number may restart electrical service upon receipt of the number. Where the number was determined sequentially, a client device may determine its own random number and compare it to the received number. If a match occurs, electrical service can be restarted. | 01-27-2011 |

20110172837 | SYSTEM AND METHOD FOR ESTIMATING AND PROVIDING DISPATCHABLE OPERATING RESERVE ENERGY CAPACITY THROUGH USE OF ACTIVE LOAD MANAGEMENT - A utility employs an active load management system (ALMS) to estimate available operating reserve for possible dispatch to the utility or another requesting entity (e.g., an independent system operator). According to one embodiment, the ALMS determines amounts of electric power stored in power storage devices, such as electric or hybrid electric vehicles, distributed throughout the utility's service area. The ALMS stores the stored power data in a repository. Responsive to receiving a request for operating reserve, the ALMS determines whether the stored power data alone or in combination with projected energy savings from a control event is sufficient to meet the operating reserve requirement. If so, the ALMS dispatches power from the power storage devices to the power grid to meet the operating reserve need. The need for operating reserve may also be communicated to mobile power storage devices to allow them to provide operating reserve as market conditions require. | 07-14-2011 |
