A system for managing electrical consumption of a load device, the system including: a load managing device capable of adjusting the electrical consumption of the load device, and a processor configured with code to perform operations comprising: receiving information describing a quantity of electricity received by the load device from an electrical utility provider; determining that the portion of the received energy is received during a local demand interval, wherein the local demand interval has i) a local duration and a local start time that are modified based on a provider duration of a provider demand interval associated with the electrical utility provider and ii) an interval guard time at a start of the local demand interval, wherein the processor does not consider shedding load during the guard time; determining a forecasted consumption of the load device based on the portion of the received energy received during the local demand interval and on a quantity of time remaining in the local duration of the local demand interval; based on a comparison of the forecasted consumption to a demand threshold associated with the local demand interval, determining that the forecasted consumption exceeds the demand threshold; and responsive to determining that the forecasted consumption exceeds the demand threshold, adjusting the electrical consumption of the load device unless the forecasted consumption exceeds the demand threshold only during the guard interval. a load managing device capable of adjusting the electrical consumption of the load device, and a processor configured with code to perform operations comprising: receiving information describing a quantity of electricity received by the load device from an electrical utility provider; determining that the portion of the received energy is received during a local demand interval, wherein the local demand interval has i) a local duration and a local start time that are modified based on a provider duration of a provider demand interval associated with the electrical utility provider and ii) an interval guard time at a start of the local demand interval, wherein the processor does not consider shedding load during the guard time; determining a forecasted consumption of the load device based on the portion of the received energy received during the local demand interval and on a quantity of time remaining in the local duration of the local demand interval; based on a comparison of the forecasted consumption to a demand threshold associated with the local demand interval, determining that the forecasted consumption exceeds the demand threshold; and responsive to determining that the forecasted consumption exceeds the demand threshold, adjusting the electrical consumption of the load device unless the forecasted consumption exceeds the demand threshold only during the guard interval. receiving information describing a quantity of electricity received by the load device from an electrical utility provider; determining that the portion of the received energy is received during a local demand interval, wherein the local demand interval has i) a local duration and a local start time that are modified based on a provider duration of a provider demand interval associated with the electrical utility provider and ii) an interval guard time at a start of the local demand interval, wherein the processor does not consider shedding load during the guard time; determining a forecasted consumption of the load device based on the portion of the received energy received during the local demand interval and on a quantity of time remaining in the local duration of the local demand interval; based on a comparison of the forecasted consumption to a demand threshold associated with the local demand interval, determining that the forecasted consumption exceeds the demand threshold; and responsive to determining that the forecasted consumption exceeds the demand threshold, adjusting the electrical consumption of the load device unless the forecasted consumption exceeds the demand threshold only during the guard interval.
