Techniques for limiting demand from an electricity meter with an installed relay

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;
• 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.

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;
• 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.

A method performed by an electricity meter for detecting an electricity load in communication with the electricity meter, the electricity meter having at least one load control, the at least one load control being changeable between a de-energize mode and a re-energize mode, the method comprising:

• receiving a command to set the at least one load control from the de-energize mode to the re-energize mode;
• setting the at least one load control from the de-energize mode to the re-energize mode;
• measuring an electrical current of the electricity load;
• comparing the measured electrical current of the electricity load to a predetermined threshold;
• setting the at least one load control from the re-energize mode to the de-energize mode upon the measured electrical current of the electricity load exceeding the predetermined threshold at any time before an end of a predetermined time interval;
• 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.
