11. An apparatus comprising:
an energy monitor having a processor coupled to one or more modules, each module having a sensor for sampling a current of a branch circuit of an electrical panel, wherein each module includes a respective switch to control power to a load on a respective branch circuit, the processor configured to,
calculate load data of the branch circuits based on collected current samples of the branch circuits;
determine a reserve capacity as a percentage of a system capacity of power to the electrical panel based on a reserve threshold of power;
compute an available power capacity by subtracting the load data from the system capacity; and
update a first group of loads to deactivate the respective switch in response to the available power capacity falling below the reserve capacity from an increase in the load on the respective branch circuit.
