A method performed by an electricity meter for limiting an electricity load in communication with the electricity meter is disclosed. The electricity meter has at least one load control and 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. When one or more predetermined time-of-use tiers has a corresponding time-of-use demand threshold, a present time-of-use tier is determined and a present time-of-use demand for the electricity load in the present time-of-use tier is then determined. The present time-of-use demand to the time-of-use demand threshold corresponding to the present time-of-use tier is compared. The at least one load control is set to a de-energize mode upon a de-energize condition being satisfied. The de-energize condition includes the present time-of-use demand exceeding the time-of-use demand threshold corresponding to the present time-of-use tier. The de-energize mode may cause the load control (410) to open, or to otherwise assume the state required to cause the consumer's electricity load (420) to become fully or partially de-energized. At least one of the one or more predetermined time-of-use tiers can also have a corresponding demand limitation mode. The corresponding demand limitation mode is adjustable between a limit setting and a no limit setting. When one of the one or more predetermined time-of-use tiers has a corresponding demand limitation mode a present time-of-use tier is determined and the demand limitation mode of the present time-of-use tier is then determined. The at least one load control is set to a de-energize mode upon a de-energize condition being satisfied. The de-energize condition includes the demand limitation mode of the present time-of-use tier being the limit setting.
