Energy Management
by E&W Electrical, LLC
Terminology can sometimes be a bit intimidating, energy management is simply taking control of the amount of energy used.  Simply turning lights off for spaces not in use is a form of energy management, however,  management is typically accomplished by use of automatic systems which set load priority and maximum usage levels.  If this is performed correctly minimal inconvenience would be realized.  Most management systems in use, especially for residential applications, manage heating and air conditioning loads, due to these loads making up the larger block of energy consumption.

Energy management these days is a popular topic of discussion and the technology is becoming part of all energy consuming appliances.  Typically these systems were used to lower energy consumption and provide for financial savings.  Today management systems are being used to minimize the size of generator power systems, which also provides for financial savings.

Until recently especially in the residential markets, implementation of adequately sized generator systems did not always occur, which created bad potential scenarios for both the generator systems as well as the loads attached to the generator systems.  This created the need for a new electrical rule or standard which required load calculations for generator systems providing electricity to structure.  Due to the cost associated with the installation of the necessary larger generator  systems needed to satisfy this new rule, manufacturers started utilizing energy management practices so as to minimize the generator system size and ultimately cost.  By load shedding at preset load levels, lower priority loads can be disconnected keeping connected demand to levels per the installed generator system.
As per the diagram below, air conditioning typically is the larger percentage of consumption and is the easiest to manage.  Correct management of load can provide savings without inconvenience.
