System for rate-related control of electrical loads

For use with a master controller, a secondary controller for reporting the operation of a plurality of electrical loads in a customer premises, comprising:

• means for communicating with the master controller;
• means for displaying messages to the customer;
• means for obtaining from the mast controller historical energy consumption data for one or more loads;
• and
• means for generating, in response to a request, on the means for displaying, a report describing said historical energy consumption data, including the rate at which energy is being consumed at the premises and the rate at which a selected load device has been consuming energy, and wherein the indication of the rate at which a selected load device has been consuming energy is displayed for a selected interval in relation to an indication of the rate at which energy has been consumed at the premises for the selected interval.
