An electricity meter capable of performing a method for limiting an electricity load in communication with the electricity meter is disclosed. The electricity meter includes at least one load control and the electricity meter has one or more predetermined time-of-use tiers. Each of the one or more predetermined time-of-use tiers has a corresponding time-of-use demand threshold. The method comprises determining a present time-of-use tier; 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; and setting the at least one load control to a de-energize mode when a de-energize condition is satisfied. The de-energize condition may include sub-conditions such as the present time-of-use demand exceeding the time-of-use demand threshold corresponding to the present time-of-use tier.

The method of claim 1, in which at least one of the one or more predetermined time-of-use tiers has a corresponding demand limitation mode, the corresponding demand limitation mode being changeable between a limit setting and a no-limit setting, the method further comprising determining the demand limitation mode of the present time-of-use tier, and the de-energize condition further including the demand limitation mode of the present time-of-use tier being the limit setting. 3. The method of claim 1, in which the de-energize mode causes at least a part of the electricity load to become electrically de-energized. 4. The method of claim 1, in which the electricity meter has a tier override mode and the electricity meter is also in communication with an electricity control network, the electricity control network capable of commanding the electricity meter into the tier override mode, the method further comprising: setting the electricity meter to the tier override mode; andadjusting the time-of-use demand threshold corresponding to the present time-of-use tier, the adjusted time-of-use demand threshold being maintained for a duration of time in which the electricity meter is the tier override mode. 5. The method of claim 2, in which the electricity meter has a tier override mode and the electricity meter is also in communication with an electricity control network, the electricity control network capable of commanding the electricity meter into the tier override mode, the method further comprising: setting the electricity meter to the tier override mode; andsetting the demand limitation mode of the present time-of-use tier to the no-limit setting, the no-limit setting being maintained for a duration of time in which the electricity meter is in the tier override mode. 6. The method of claim 1, in which the electricity meter receives the lockout control override either remotely from an electricity control network or via a local communication port of the electricity meter. 7. 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, at least one of the one or more predetermined time-of-use tiers having a corresponding demand limitation mode, the corresponding demand limitation mode being adjustable between a limit setting and a no-limit setting, the method comprising: determining a present time-of-use tier of the one or more predetermined time-of-use tiers;determining the demand limitation mode of 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 demand limitation mode of the present time-of-use tier being the limit setting;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; andmaintaining 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. 8. The method of claim 7, further comprising: maintaining the at least one load control in the de-energize mode for at least a duration of the present time-of-use tier. 9. The method of claim 7, in which the de-energize mode causes at least a part of the electricity load to become electrically de-energized. 10. 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, the method comprising: determining a present time-of-day;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-day being within a predetermined range of time-of-day;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; andmaintaining 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. 11. The method of claim 10, further comprising: maintaining the at least one load control in the de-energize mode for at least a period of time beginning at a time-of-day the at least one load control is set to the de-energize mode and ending at a predetermined time-of-day corresponding to the predetermined range of time-of-day. 12. The method of claim 10, in which the de-energize mode causes at least a part of the electricity load to become electrically de-energized. 13.
