1. A system, comprising:

  • a system controller comprising;

    a system controller processing subsystem;

    a first transceiver coupled to the system controller processing subsystem and configured to transmit messages to and receive messages from a plurality of wireless controllers, each of the wireless controllers being respectively associated with only one corresponding managed entity where a managed entity is an entity at a location having an account with an energy provider, and wherein there is at least a first managed entity associated with a first wireless controller at a first location for which a first wireless smart metering device monitors power delivery and consumption, and a second managed entity associated with a second wireless controller at a second location for which a second wireless smart metering device monitors power delivery and consumption;

    a data storage device coupled to the system controller processing subsystem and storing data describing the association of managed entities with the wireless controllers, including the association of the first managed entity with the first wireless controller and the second managed entity associated with the second wireless controller, and instructions executable by the system controller processing subsystem and in response to such execution cause the system controller to perform operations comprising;

    transmit a poll message to the first wireless controller;

    receive, in response to the poll message, a resource list describing power control devices located at the first location and communicating with the first wireless controller; and

    generate power management rules that define power management processes to be taken in response to an event message received by the first wireless controller from the wireless smart metering device and transmit the respective power management rules to the first wireless controller;

    wherein the first wireless controller comprises;

    a wireless controller processing subsystem;

    a communication subsystem coupled to the wireless controller processing subsystem and configured to;

    transmit messages to and receive messages from a plurality of power control devices over a first network according to a first protocol;

    transmit messages to and receive messages from the first wireless smart metering device over a second network according to a second protocol, wherein the second protocol is different from the first protocol; and

    transmit messages to and receive messages from the system controller over a third network over a third protocol that is different from the first protocol and the second protocol;

    a data storage device coupled to the wireless controller processing subsystem and storing instructions executable by the wireless controller processing subsystem and in response to such execution cause the first wireless controller to perform operations comprising;

    in response to receiving the poll message from the system controller, transmit to the system controller the resource list;

    receive an event message from one or more of the wireless smart metering device over the second network or the system controller over the third network;

    receive the power management rules from the system controller;

    generate one or more power commands for the power control devices based on the power management rules, the one or more power commands configured to cause the power control devices to adjust one or more power loads in response to the event message; and

    transmit the one or more power commands to the power control devices over the first network.
