Change Summary

• New Article 750, Energy Management Systems defines and controls building systems while protecting the safety concerns of the NEC or building codes
• With the application of the Smart Grid, premises energy management systems must be compatible with NEC safety concerns
• Article 750 provides a safe and systematic approach for load shedding and disconnection of power

Expert Analysis

New Article 750, Energy Management, was the work of the Smart Grid Task Group. Energy Management has become common place in today’s electrical infrastructure through the control of utilization equipment, energy storage and power production. Yet, limited consideration is found in installation standards in actively managing these systems as a means to reduce energy cost or support peak power needs as it relates to a broader electrical infrastructure demand. Energy Management has two basic aspects, monitoring the system and controlling some portions of the system. These two basic elements must be separated in order to permit an energy management system to monitor and possibly restrict those areas of control that would adversely impact the electrical system or personal safety. The most important aspect here is to make sure an overall energy management system does not override a system specific to preventing load shedding of alternate power sources for fire pumps and emergency systems. Certain energy management systems become critical to ensure safety. For example, turning off ventilation systems for hazardous (classified) material, or a moving walkway causing someone to fall, are examples of where load management controls need to be restricted.
