An apparatus includes a network operations center and a first control node. The network operations center provides configuration data to the system of energy consuming devices. The first control node is coupled to the network operations center and a second control node via the network. The first control node has a node processor and a global schedule module. The node processor operates a first energy consuming device to maintain a first local environment. The global schedule module is coupled to the first node processor, and coordinates run times for the first energy consuming device and a second energy consuming device based on a replica copy of a global run time schedule disposed within the first and second control nodes, an adjusted first descriptor set characterizing the first local environment, an adjusted second descriptor set characterizing a second local environment, and the configuration data provided by the network operations center.
