Abstract:
1. A method performed by an electricity meter for limiting an electricity load in communication with the electricity meter, the electricity meter having at least one load control and the electricity meter having one or more predetermined time-of-use tiers, each of the one or more predetermined time-of-use tiers having a corresponding time-of-use demand threshold, the method comprising: determining a present time-of-use tier of the one or more predetermined time-of-use tiers; determining a present time-of-use demand for the electricity load in the present time-of-use tier; comparing the present time-of-use demand to the time-of-use demand threshold corresponding to the present time-of-use tier; setting the at least one load control to a de-energize mode upon a de-energize condition being satisfied, the de-energize condition including the present time-of-use demand exceeding the time-of-use demand threshold corresponding to the present time-of-use tier; determining a number of instances in which the at least one load control is set to the de- energize mode over a predetermined period of time; comparing the number of instances to a predetermined instance threshold corresponding to the predetermined period of time; and maintaining the at least one load control in the de-energize mode upon the number of instances exceeding the predetermined instance threshold, the maintaining continuing until the electricity meter receives a lockout control override.
