A method and system for estimating energy consumption of a utility population includes organizing the utility population comprising energy consumers into a plurality of groups. Next, a distribution of energy consumption against the plurality of groups may be calculated. Subsequently, statistically representative groups based on the energy distribution and the plurality of groups may be determined. Data is then collected from the statistically representative groups at predefined intervals from a communications network. Energy consumption of the utility population may then be estimated based on the data collected from the statistically representative groups. The communications network comprises an advanced metering infrastructure (AMI) network.

A method and system for managing an energy supply of a utility provider include calibrating one or more climate controlled spaces for a controller. The calibrating may include calculating a heating/cooling ratio for the one or more climate controlled spaces. After this calibration occurs, the system may determine if an energy supply surplus exists. If an energy supply surplus exists, then the system may start using the one or more climate controlled spaces as energy sinks for expending energy according to the heating/cooling ratio. The system may also determine if an energy supply deficit exists and if an energy supply deficit exists, then the system may start using the one or more climate controlled spaces as energy 'sources,' in which a direct load control algorithm is used to reduce energy consumption by the one or more climate controlled spaces.

A method and system for controlling a unitary room air conditioner and for reducing peak loads can comprise a communications transceiver coupled to a relay or switch. This relay or switch can control the flow of electricity to a compressor of the air conditioner. The communications transceiver can receive signals which may direct the communications transceiver to open or close the relay or switch. In this way, the compressor can be controlled independent of the air conditioner's control logic. In other words, the operation of the compressor can be controlled with signals which originate outside of the unitary air conditioner and independent of the air conditioner's own internal control logic.

A method and system provide for the cooperative powering of unitary air conditioners. The method and system includes coordinating powering of unitary air conditioners in a multiunit building or other low level of aggregation in a power grid. Multiple unitary air conditioners can use a power line communication (PLC) communication module for communicating with other air conditioners that are within the same multiunit building. According to one aspect of the method and system, by using power line communications, multiple unitary air conditioners within a single building can form self-contained local area networks. The LAN can also support a token ring network. According to this token ring network, a predetermined number of tokens can be assigned within the token ring network.

A method and system for curtailing energy consumption of an appliance, such as an air conditioning compressor or heat pump, is provided. A control unit stores information relating to the load, which may include a connected load value, such as a power consumption value or efficiency rating. The control unit then monitors the appliance to determine when the appliance is calling for energy. Upon receiving an energy reduction value from a remote source, the control unit then calculates a permitted run time from the energy reduction value and the connected load value. The control unit, through a switch, then permits the appliance to be operable only for the permitted run time so as to reduce power consumption by a predetermined amount.
