Abstract

A system and method are provided for managing energy usage that includes obtaining an allocated power value associated with a predetermined time period, metering at least one of consumed power and corresponding consumed energy to determine a consumed power value and a consumed energy value and prompting for a reduced load condition when the consumed power value exceeds the allocated power value. The system and method may further include obtaining a line voltage value, comparing the line voltage value to a threshold voltage value, and obtaining energy saving parameters that define a reduced voltage value. A reduced power value that corresponds to the reduced voltage value may be supplied, the reduced power value being supplied when the line voltage value exceeds the threshold voltage value.
