How demand response programs function and participation
Demand response programs pay customers to reduce or shift electricity use during peak periods or grid stress events. These programs improve grid reliability and lower system costs by reducing peak demand instead of building additional generation.
Program mechanics
- Notification: Utilities or program operators signal when to curtail usage, often through automated systems or alerts.
- Actions: Participants reduce consumption by adjusting HVAC, deferring equipment, using onsite generation or discharging batteries.
- Compensation: Payments can be based on participation, measured reduction or performance during events.
Who can participate
- Residential customers: Many utilities offer simple residential programs with minimal setup, such as smart thermostat cycling or time-of-use incentives.
- Commercial and industrial customers: Larger customers can enroll in programs that provide higher payments for reliable curtailments or capacity commitments.
- Aggregators: Aggregators combine many small resources into a single offer to the market, enabling participation by customers who couldn’t join individually.
Types of programs
- Price-based: Time-of-use or real-time pricing encourages behavioral shifts without direct event notifications.
- Incentive-based: Customers get payments for complying with dispatch or for maintaining a baseline reduction during events.
Considerations for participants
- Operational impact: Evaluate how curtailments affect operations and whether flexibility can be automated.
- Contract terms: Review performance obligations, penalties and payment schedules.
Demand response provides revenue opportunities and grid support. Businesses and homeowners with flexible loads, batteries or smart controls can often find programs that match their capabilities and tolerance for curtailment.
