Installed on the utility side of an electrical service, a smart meter allows the utility to determine the quantity and time of electricity usage for setting rates and assessing charges. Installed on the facility side of an electrical service, a submeter allows an owner/operator to track quantity and time of electricity usage according to department, tenant, floor, or load type.
Consulting and specifying engineers can help their clients realize benefits with minimal investments by encouraging them to consider smart meters and submeters. Smart meters can help owners/operators manage (and, in many cases, lower) their electrical demand charges and prepare for the Smart Grid. Submeters may help them allocate charges by tenant or department as well as help them qualify for LEED points.
