1. A method for controlling an energy control system having a grid interconnection electrically coupled to a utility grid, a backup load interconnection electrically coupled to a plurality of backup loads, a non-backup load interconnection electrically coupled to a non-backup load, and a backup power interconnection electrically coupled to a backup power source, comprising:
interconnecting, by a microgrid-interconnection device, the grid interconnection, the backup load interconnection, the non-backup load interconnection, and the backup power interconnection;
supplying, through the microgrid-interconnection device, power received from the grid interconnection to the non-backup load interconnection and the backup load interconnection, wherein the microgrid-interconnection device is disposed electrically downstream from the utility grid and electrically upstream from the non-backup load and the plurality of backup loads;
receiving electronic data from the plurality of backup loads electrically coupled to the backup load interconnection;
detecting a power outage at the grid interconnection electrically coupled to the utility grid;
disconnecting, by the microgrid-interconnection device, the grid interconnection and the non-backup load interconnection from the backup power interconnection electrically coupled to the backup power source; and
supplying power from the backup power source to a first set of the plurality of backup loads through the backup load interconnection and the backup power interconnection; and
wherein the first set of the plurality of backup loads is determined based on the electronic data from the plurality of backup loads.
