Emergency Demand Response is a rapid reduction of electrical loads initiated by a utility during grid emergencies or critical peak periods to prevent blackouts. This program calls on participating commercial and industrial customers to immediately curtail energy consumption within minutes. Emergency demand response differs from scheduled demand response by its urgent, unplanned nature and higher compensation rates.
Technical Details
Emergency demand response events typically require load reduction of 10-50% within 10-15 minutes of notification. HVAC systems represent major controllable loads in most facilities, commonly contributing 30-50% of total demand reduction. Participating facilities must have automated response capabilities integrated with their building management systems. Response obligations vary by program, with some requiring commitment to specific load reduction targets. Utilities compensate participants at premium rates, typically 2-5 times higher than standard demand response payments, ranging from $0.50 to $2.00 per kilowatt reduced.
Participation Requirements
Facilities must install communication equipment and automated controls to respond automatically to emergency signals. Most programs require baseline consumption data and pre-determined shedding protocols. Successful participation requires proper HVAC design and control sequencing to shed loads while maintaining occupant safety and comfort.
