Patent number: 7565227Abstract: An energy usage coordinator controls the energy usage of individual buildings of a group (or portfolio) of buildings in one or more load zones. These buildings have all contracted with an energy company which controls (directly or indirectly) the energy usage coordinator. By agreeing to lower energy usage during times of peak usage (when the energy company may otherwise have to pay very high prices on the spot or short term market), the owners or managers of the buildings receive a preferential energy rate from the energy company. Such a preferential rate may be in the form of a fixed rate reduction or a variable rate reduction. Alternatively, the energy company may determine that the energy is currently selling for twice what its building portfolio has contracted to pay for it so it requests some portion of the portfolio to reduce usage so that it can sell the excess/saved energy in the market.Type: GrantFiled: August 15, 2007Date of Patent: July 21, 2009Assignee: Constellation Energy Group, Inc.Inventors: Amy Richard, Peter Kelly-Detwiler, Joseph Franz

Patent number: 7561977Abstract: A system that facilitates and implements energy savings decisions by a home owner. The system will provide a mechanism to reduce the peak level of energy demand. A controller in logical communication with energy consuming appliances responds to request for energy from energy consuming appliances and devices by permitting or curtailing energy supply to the appliances or devices based on evaluation of a plurality of logical considerations. The controller may be operated to provide energy to fewer than all of the energy requesting appliances to reduce the energy demand on an energy supply source, including the instantaneous peak demand.Type: GrantFiled: June 13, 2003Date of Patent: July 14, 2009Assignee: Whirlpool CorporationInventors: Gale Richard Horst, Jiannong Zhang, Andriy Dmytrovych Syvokozov

Publication number: 20090177595Abstract: A metering device that allows the two-way exchange of electrical energy between the power grid and electric vehicles by giving customers the option to upload electrical energy from their vehicle's electrical power system to the power grid or to another vehicle, or the option to download electrical energy from the power grid or another vehicle, to charge their vehicle's electric storage system, depending on the current market price of electricity. This allows users to both buy and sell electricity as a commodity to offset their fuel costs and to generate income. The metering device and the associated server may maintain a database of the user's preferences and identification.Type: ApplicationFiled: October 6, 2008Publication date: July 9, 2009Inventors: Stephen David Dunlap, William Bennett Morrow, Jacqueline Frances Timte

Patent number: 7545285Abstract: A load control system that communicates with existing automated meter reading communications systems to interrupt and shed loads at a customer location. The system includes a master controller that listens to communications between a utility meter and the reading system. The controller receives tier and/or pricing information and will instruct a load control unit to interrupt certain loads based on the information. In addition, the system may be employed as a load shedding system where a command may be forwarded to the master controller to disconnect loads based on action levels. The command may be sent via a TCP/IP communications system to a node in the reading system and the forwarded via a radio network to the master controller to reduce latency. Predictive shedding may be performed based on forecast loads.Type: GrantFiled: February 16, 2006Date of Patent: June 9, 2009Assignee: Elster Electricity, LLCInventors: Kenneth C. Shuey, Andrew J.
