An energy management system is permitted to perform which action on busbars and conductors supplied by interconnected sources?

• A. Monitor output voltage
• B. Backfeed the system
• C. Limit current and loading
• D. Terminate connections

Answer: (C)

The energy management system is designed to regulate how power flows in a network that has multiple interconnected sources. On busbars and conductors that are fed by those interconnected sources, the EMS is allowed to limit current and loading. This control action helps prevent overcurrent conditions, manage voltage levels, and maintain stable operation across the interconnected sources by restricting the amount of power that can be drawn or exported. Monitoring output voltage is important, but it’s a measurement function rather than an active control action. Backfeeding the system is typically not permitted unless specifically allowed by interconnection agreements and protective schemes, and terminating connections is typically handled by protective devices rather than the EMS itself.
