The total accumulated switched-off shortcurrents by a circuitbreaker or

the number of generator starts are a trigger for maintenanceNo need for big oversizing of primary equipment

In case of a shortage of electrical power, secure the available power to critical loads by

switching off the none important loads according to dynamic load tables

Optimizing the stability of the operation of the electrical generation- and distribution

network of an industryLimiting electrical import during peak time

and decreasing peak base chargeMaintaining a good Power Factor

The Human Machine Interfaces for all the electrical sub-systems can be integrated in

the Energy Management SystemSerial interfaces with protection & control units avoid spaghetti wiring & cable ducts

Power Control, Standby Optimization, n+1 Criteria, SCADA, etc. are performed by

the system and not anymore by the operators
