A system where electricity consumers adjust their power usage in response to time-based rates or other incentives to help balance grid supply and demand.

Demand Response

Demand response (DR) represents a critical component of modern smart grid systems, enabling a more flexible and resilient electricity network by actively managing consumer power consumption patterns.

Core Mechanisms

The fundamental principle of demand response relies on two key mechanisms:

Price-based DR
- Time-of-use (TOU) pricing
- Real-time pricing
- Critical peak pricing
- Electricity Markets rate structures
Incentive-based DR
- Direct load control
- Interruptible service programs
- Energy Storage bidding
- Emergency demand reduction

Implementation Methods

Automated Systems

Modern demand response typically employs Smart Meters and Building Automation to automatically adjust consumption based on:

Grid signals
Price thresholds
Environmental conditions
User preferences

Manual Response

Some programs rely on consumer behavior modification through:

Mobile notifications
Web portals
Energy Management Systems interfaces
Educational initiatives
