1. A system for managing electrical demand corresponding to a plurality of electrical loads and a power generation source each coupled to a power grid, wherein each of the plurality of electrical loads is coupled to a corresponding thermal reserve such that operation of the electrical load increases the corresponding thermal reserve, the system comprising:
a controller arranged at a first one of the plurality of electrical loads, the controller configured to:
store past power usage of the first one of the plurality of electrical loads,
generate a device model based upon the past power usage of the first one of the plurality of electrical loads and the corresponding thermal reserve, and predict a future thermal reserve of the first one of the plurality of electrical loads based on the device model,
send the future thermal reserve to a centralized control,
receive a demand response signal based on the future thermal reserve from the centralized control, and
selectively turn the first one of the plurality of electrical loads on or off based on the demand response signal.
