Key Industry Challenges:

Making DR a More Automated, Ubiquitous, and Reliable Resource

Coordinate Demand Response Research

to Address Industry Needs

Expand Opportunities for

Electrification to Enhance Customer

Productivity

Electricity as an end-use solution to benefit customers and society


Load Management

• Long term load management—Energy Efficiency

– Motivated by legislated policy, internal policy

• State PUCs (IOUs)

• Economics of capital expense

• Other internal drivers

• Short term load management—Demand Response &

Renewable Integration

– Motivated by system needs

• Distribution feeder loading

• Wind & solar integration

• Peak load management


Load Management—Traditional

• Load management has been around for years…

– Energy Efficiency & DR programs

• Static loads are switched off

– Relay control

• Water heaters

• Air conditioners

• Swimming pool pumps

– Phone calls, or other signal

• Industrial & large commercial operations

• Communication is typically one-way

Easy

Button


Load Management—Future

• Move from static ON-OFF type systems

• Same device provides Energy Efficiency and Demand

Response

– Load management across all time periods

• Turn loads into load management resources

– 2-way communication

– Variability

– Flexibility

– Distributed intelligence

– Open protocols
