Limit electrical import during peak time and reduce peak based charges

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

the system and not by the operators Maintaining a good Power Factor

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

of a plant

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

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
