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.

26. A system for managing environmental comfort at a site of a customer, the site having a temperature and environment management system, the temperature and environment management system being supplied with energy from an energy provider through a distribution network, comprising:
-
a temperature sensor for sensing air temperature at the site; and
,a thermostatic device for receiving a characteristic of the energy, the thermostatic device being coupled to the temperature sensor and capable of receiving input from a user, the input including a temperature setpoint and an operational scenario, the thermostatic device being operable to control the temperature and environment management system to maintain air temperature at the site as a function of the user selected temperature setpoint, the characteristic of energy, and the selected scenario. - View Dependent Claims (27, 28, 29, 30, 32, 34, 35, 36, 37, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93)
