`ABSTRACT
`
`A System and method manage delivery of energy from a
`distribution network to one or more Sites. Each Site has at
`least one device coupled to the distribution network. The at
`least one device controllably consumes energy. The System
`includes a node and a control System. The node is coupled
`to the at least one device for Sensing and controlling energy
`delivered to the device. A control System is coupled to the
`node and distribution network for delivering to the node at
`least one characteristic of the distribution network. The node
`for controls the Supply of energy to the device as a function
`of the at least one characteristic.

`
`FIELD OF THE INVENTION
`0002 The present invention relates generally to the deliv
`ery of a commodity, and more particularly, to a System and
`method for managing the delivery and usage of a commodity
`Such as electricity, natural gas, Steam, water, chilled or
`heated water, or potable or recycled water.
`
`BACKGROUND OF THE INVENTION
`Traditionally, utilities have done an excellent job of
`0.003
`providing a reliable Source of power to their customers.
`Utilities do this by accurately predicting consumer demand
`and then ensuring that they have adequate generation
`resources available to meet that demand. Historically,
`demand for power increases each year during peak heating
`and cooling months, resulting in a need for ever increasing
`amounts of generation capacity. A review of the peak period
`demand clearly show that the need for a Substantial amount
`of new generation assets could be eliminated if there was a
`way to shift Some of the demand from peak to off peak times.
`0004. The deregulation of the electric industry has
`heightened concerns over power outages, price volatility and
`how the eventual outcome will impact the economy and our
`way of life.
`0005 For example, recent events in California have cap
`tured the headlines and amplify these concerns. California
`Suffers from 10 years of load growth with no new generation
`facilities being built to meet the demand. Internet data
`centers like the one in San Jose represent unanticipated new
`demands for power 24 hours a day equal to that of 60,000
`homes. State mandated deregulation activities forced the
`major utilities to Sell off their generation assets resulting in
`them having to buy the power they used to Self generate
`from others.
`0006 Demand reduction programs and more advanced
`controls have been proposed to assist in reducing demand
`during peak times.
`0007 Currently, utilities do offer demand reduction pro
`grams to their customers. These programs are designed to
`shift loads out of peak periods by providing a financial
`incentive for consumers to move loads to a time when it is
`leSS expensive for the utility to produce or obtain power.
`Time of day rate is an example of Such a program.
`0008 Another type of program offered by utilities is the
`traditional Demand Side Management (DSM) program. This
`type of program provides the customer a monthly credit for
`allowing the utility to interrupt power to major loads in their
`home during peaks or emergencies.
`
`0009 While both of these programs have been shown to
`work, they each have their problems. Time of day rate
`programs may be difficult for customers to understand.
`Therefore these programs have a very low participation rate
`among the customer base. DSM programs, on the other
`hand, have a much higher participation rate. However, DSM
`loadsheds are seldom exercised by the utility. And, when the
`utility does exercise a loadshed, the resulting interruption of
`power tends to affect customer comfort, thereby causing
`large numbers of customers to drop out of the program. In
`addition, current DSM programs cannot differentiate
`between those consumers that contribute to a load control,
`and those that don’t, while providing incentive credits to all
`who sign up.
`0010 While both time of day rates and DSM programs
`can be effective, each have challenges in the area of cus
`tomer Satisfaction that erode their usefulness. In addition,
`utilities earn little revenue from these types of offerings and
`therefore look to new generation as a more economically
`viable option.
`0011. Thermostats, thermostatic control devices and
`environmental control Systems have been designed, manu
`factured and placed in use for many years. These devices are
`primarily designed to Sense the temperature inside a site 1.04
`and based on occupant designated Setting, activate the
`heating and/or air conditioning System or Systems to main
`tain a comfort level based on the occupants designated level
`of comfort. There are two main types of design for these
`devices: a Standard Single control device or a dual control
`System.
`0012. The standard single control device can be set to
`activate a heating or cooling System based upon a manual
`Switch to Select either System and a degree Setting mecha
`nism to Select the desired temperature to heat or cool to if the
`temperature falls or rises below or above the occupant
`designated Set point. A dual control System is attached to
`both a heating and cooling System which has two Set points,
`one for the heating System activation and one for the cooling
`System activation. With this type of a control, the user Sets
`a desired minimum temperature, below which the heating
`System will be activated to raise the temperature during
`winter Seasons, and a maximum temperature, above which
`the cooling System will be activated to drop the temperature
`during Summer Seasons.
`0013 This type of temperature control device provides
`the occupant the convenience of not having to manually
`Select either the heating or cooling System, as is the case of
`the Standard Single control device, and allows the occupant
`to define a temperature range between which they are
`comfortable. Using these two main types of design as a base
`line, there are many variations, which have been developed
`over time. Over the years, these Sensing and control devices
`have moved from traditional bi-metal contractors to more
`Sophisticated electronic devices over the years, and have
`incorporated the ability to be programmed with multiple Set
`points for both heating and cooling as well as having the
`ability to activate these different set points based on time of
`day, day of week, and/or externally generated control signals
`from utility companies indicating a fixed cost tier that is in
`effect, e.g., low, medium, high & critical, and to interface
`with an infra-red motion Sensor that automatically Sets back
`the temperature to a predetermined point based on the

`
`presence of a perSon in the area. However, most end use
`consumers do not have the time, experience, and/or acceSS
`to data to monitor, track, and use these devices.
`0.014. The present invention is aimed at one or more of
`the problems set forth above.
`
`SUMMARY OF THE INVENTION
`0.015. In one aspect of the present invention, a system and
`method manage delivery of energy from a distribution
`network to one or more Sites. Each Site has at least one
`device coupled to the distribution network. The at least one
`device controllably consumes energy. The System includes a
`node and a control System. The node is coupled to the at least
`one device for Sensing and controlling energy delivered to
`the device. A control System is coupled to the node and
`distribution network for delivering to the node at least one
`characteristic of the distribution network. The node for
`controls the Supply of energy to the device as a function of
`the at least one characteristic.
`0016. In another aspect of the present invention, a
`method of shifting energy requirements from a first period of
`time is provided. The method includes the Steps of measur
`ing energy usage of a controlled device operated by a
`customer, cutting off energy to the controlled device during
`the first time period, and providing a rebate to the customer
`based on actual energy Savings as a function of the first time
`period, the measured energy usage, and known power
`requirements.
`0.017. In still another aspect of the present invention, a
`thermostat device for controlling a heating and/or cooling
`System through interaction with a user is provided. The
`heating and/or cooling System are Supplied with energy
`through a power distribution network. The thermostat
`includes a control panel for receiving input from the user and
`a display coupled to the control panel for visually presenting
`information to the user. The thermostat device is adapted to
`receive a characteristic of the energy being Supplied and for
`displaying the characteristic on the display.

`
`DETAILED DESCRIPTION OF THE
`INVENTION
`0057 1. Energy Management System and Methods
`Overview
`0.058 With reference to the drawings, and in operation,
`the present invention relates generally to a System 1.02 and
`method for managing the delivery and usage of a commod
`ity, Such as electricity, natural gas, Steam, water, chilled or
`heated water, or potable or recycled water. More Specifically,
`the System 1.02 is adaptable to manage the delivery and
`usage of energy, e.g., electricity and natural gas. While the
`below discussion focuses on the management of the delivery
`and/or usage of electricity, the present invention is not
`limited to Such the delivery and/or usage of electricity.
`0059. In general, the system 1.02 allows at least one
`customer (or user) located at a customer Site (indicated by
`reference number 1.04) and/or a utility (indicated by refer
`ence number 1.06) to manage delivery or usage of the
`electricity to the customer's site 1.06. The utility 1.06 may
`include both the generation of the electricity, e.g., via power
`plants, and/or the transmission of electricity to the customer
`sites 1.04.
`0060. The customer site 1.04 includes at least one device
`1.08 which uses electricity and at least one node 1.10. In the
`illustrated embodiment, the customer site 1.04 includes three
`devices: a metered device 1.08A, a controlled device 1.08B,
`and a metered and controlled device 1.08C. Each device
`1.08 may have an associated node 1.10.
`0061 AS discussed in more detail below, in the illustrated
`embodiment, there are four different types of nodes 1.10: a
`load metering node 1.10A, a control node 1.10B, a load
`control node 1.10C, and a gateway node 1.10D.
`0062) The gateway node 1.10D provides two way com
`munication between the gateway 1.10D and each other node
`1.10A, 1.10B, 1.10C and between the gateway node 1.10D
`and a utility control system 1.12. It should be noted that
`although there are only one of each the devices 1.08A,
`1.08B, 1.08C, shown, there may be any number of each type
`of device 1.08A, 1.08B, 1.08C (including zero).
`
`0063. The load metering node 1.10A, in general, mea
`Sures the instantaneous power being delivered (typically, in
`kWh) to the associated metered device 1.08A. The load
`metering node 1.10A may also determine the total power
`delivered to the metered device 1.08A over a predetermined
`period of time, e.g., every 15 or 20 minutes. Information
`related to the instantaneous power being delivered and the
`accumulated power is delivered to utility 1.06 via the
`gateway control node 1.10D. For example, the metered
`device 1.08A may be an electricity meter which measures all
`power being Supplied to the customer Site 1.04.
`0064. The control node 1.10B, in general, is used to
`control the controlled device 1.08B. In the simplest form the
`control node 1.10B may controllably cut off and supply
`power to the controlled device 1.08B. For example, if the
`controlled device 1.08B is a pool pump used to filter a pool
`(not shown), the control node 1.10B may simply turn power
`to the pool pump on and off. Alternatively, the control node
`1.10B may have control over features of the controlled
`device 1.08B, e.g., Start time, end time, duration, etc.
`0065. The load control node 1.10C, in general, is used to
`both measure the instantaneous power being delivered to the
`controlled and metered device 1.08C and controls the device
`1.08C. The load control node 1.10C may also determine the
`total power delivered to the metered and controlled device
`1.08C over a predetermined period of time, e.g., every 15 or
`20 minutes.
`0.066 Nodes 1.10 may be utilized with any type of device
`1.08 for which it is desirable to control and/or measure its
`power usage. For example, nodes 1.10 may be associated
`with the entire customer site 1.04, a pool pump, an HVAC
`System, a water heater, any appliance, Such as a refrigerator,
`dishwasher, hot tubs, irrigation and well pumps, Spas, coffer
`maker, etc., or other electrical or electronic device, e.g.,
`televisions, Stereos, etc.
`0067. The type of node 1.10 which is used with a device
`1.08 is dependent upon the device and whether it is desirable
`to measure the device's power usage, control the device or
`both. In one aspect of the present invention a node 1.10 may
`be separate from the device 1.08. For example, in each
`device 1.08 it may be desirable to measure the energy usage
`of the entire customer site 1.04. Thus, a load metering node
`1.10A may be associated with the site's electric meter.
`0068 Nodes 1.10 may either be integrated with the
`corresponding device 1.08 or be separate. For example, a
`load metering node 1.10A may be a separate device which
`is coupled to an electric meter (for retro-fit purposes).
`Alternatively, nodes 1.08 may be designed and manufac
`tured to be integral with the devices 1.10.
`0069. The customer may access and control the system
`1.02 through a user interface 1.14 (see below). The user
`interface 1.14 may be incorporated into another device, Such
`as a thermostat (see below). Additionally, the customer may
`be given access to the System 1.02 through external devices,
`Such as, mobile phones, person
