A method and system for energy management via energy-aware process scheduling provides per-process energy use / power dissipation control to manage system energy requirements and thermal conditions without throttling overall system performance. Use of energy by a particular process is measured or is estimated from resource requirements that are determined by the operating system or reported by the application owning the process. The scheduler then determines whether or not to allocate execution slices to the process in conformity with the measured or estimated energy requirements of the process. The scheduler may insert “idle” execution slices to reduce energy use / power dissipation or may prefer low energy-use processes over high energy-use processes. Pragmatic faults may be issued as warnings from the operating system to an application to indicate that energy requirements need to be curtailed. If the warning sent to the application does not result in sufficient energy use / power dissipation reduction, then the scheduler may implement the selective allocation of slices to processes that have an excessive energy requirement. The scheduler may be notified of such a condition through pragmatic “critical” faults that indicate a higher degree of severity than the previously-issued warning faults.

A system for shifting energy demand from on-peak time windows to off-peak time windows by using hot water heater load shifting, while providing the end user with the level of service (i.e., availability of hot water) according to the user's customary use described by service quality criteria. The shift is accomplished by a controller located at the end user establishment and in communication with a central control server. The controller monitors local water heater upper and / or lower temperature and controls upper and / or lower water heater heating elements in accordance with a demand shift process commanded by the central control server. The controller may determine usage and remaining capacity for reporting back to the central control server. A volumetric capacity and usage determination is disclosed. The control server may select water heaters according to use patterns and / or measured capacity. One embodiment is adapted for use with existing water heaters without disrupting safety features of the existing water heater.

A method to calculate energy demand in an energy generation, transmission and distribution network including one or more power plants based on different energy source types including renewable energy, a communications system and one or more local consumption metering units. A customer demand profile for one or more customers is provided. A customer-specified proportion of power demand to be supplied from a given energy source type is registered. A total predicted energy demand dependent is calculated in part on an accumulated demand for the given energy source type.

Described herein are methods and systems, including computer program products, for optimizing and controlling the energy consumption of a building. A first computing device generates a set of thermal response coefficients for the building based on energy characteristics of the building and weather data associated with the location of the building. The first computing device predicts an energy response of the building based on the set of thermal response coefficients and forecasted weather associated with the location of the building. The first computing device selects minimal energy requirements of the building based on an energy consumption cost associated with the building. The first computing device determines one or more temperature set points for the building based on the energy response and the minimal energy requirements. The first computing device transmits the one or more temperature set points to a thermostat of the building.

A method for managing electrical demand on a power grid in response to electrical supply conditions is described. The method includes determining a first energy demand forecast using stored information, determining a first energy supply forecast based on a known energy production and transmission capacity, and comparing the first energy demand forecast to the first energy supply forecast. The method also includes transmitting at least one of an adjusted price signal and an electrical load shedding signal to a customer over a bi-directional communication system based on the comparison of the first energy demand forecast to the first energy supply forecast.

Fully automated demand response may be implemented at end users, in accordance with terms agreed to by end users to reduce energy demand during demand response events. Demand reduction actions to implement the objectives of a demand response event at the end users may be determined, desirably using artificial intelligence and neural networks, based on energy demand curtailment objectives of the demand response event, hierarchy(ies) of demand reduction actions for respective demand response events ordered to minimize undesired impact at the end users, and monitoring data received from, or relating to implementing energy demand curtailment at, the end users. In addition, demand reduction actions may be automatically implemented at end users in the absence of a demand response event, to implement energy demand curtailment according to criteria of end users, where the demand reduction actions are determined based on monitoring data and a hierarchy(ies) of demand reduction actions and using artificial intelligence and neural networks.

The invention relates to an energy storing method and apparatus for use by end-users of energy, such as commercial property owners and operators. The system differs from past systems, insofar as it is not intended to be used by and in connection with energy suppliers, such as large utility and power supply plants and grids. The system preferably relates to the manner in which an end-user of energy can implement energy and costs savings, by using energy storage and time-shifting methods, to control and regulate the consumption of energy in a manner that achieves a cost savings over a period of time. One aspect of the method relates to accurately forecasting and predicting the energy demands and peaks that might occur on a daily basis, by recording and analyzing the prior day's history, as well as the overall energy demand histories, using short and long term forecasts, and then setting up a variable energy storage / use plan or schedule that helps to reduce the peak demands by time-shifting the energy that is used, i.e., reducing consumption during high demand / high cost periods, and using the energy stored during low demand / low cost periods during the high demand / high cost periods.

An apparatus for generating a heated product stream downhole is provided wherein a fuel rich mixture is reacted downhole by contact with a catalyst to produce a partially reacted product stream, the fuel rich mixture comprising fuel and oxygen. The partially reacted product stream is brought into contact with an oxidant thereby igniting combustion upon contact producing a combustion product stream. The combustion product stream may be cooled by injecting a diluent flow such as water or CO2. The cooled combustion product stream may be injected into oil bearing strata in order to reduce the energy requirements for the production of heavy oil.
