What is Demand Response?
• Management of electrical consumption
• Active alleviation of grid stress
• Load Shedding during peak demand periods

The Shocking Truth… DR is more than a “nice to
have”, it is a necessary tool for a reliable grid
• It is estimated that a 5% lowering of demand would result in a
50% price reduction during the peak hours of the Californian
electricity crisis in 2000/2001.
• If demand continues to grow unabated, to meet future demand
will require 1,300 new power plants supplying 400 GW by 2020.
• It’s not just big corporations driving up demand… It’s you too!

The Importance of Demand Response
• The Problem
– Utility grid under significant amounts of stress due to increased requirement
– Grids have not changed to meet increased energy requirements
– Utilities have increasing brown outs
– Grid stability and energy sustainability decreasing constantly
• The Solution
– Demand Response allows utilities to cut back energy demand when grid is under stress
– Demand Response allows for increased grid stability without expensive grid upgrades
– Open ADR = Automated Demand Response gives the utilities control

Developing a Comprehensive Energy Strategy is
useful for all corporations, well beyond DR alone

Eliminating complications are key to customer
acceptance
Demand Response Should Be:
• Easy
• Simple
• Reliable
Demand Response Implementation:
• Manual Demand Response Actions
• Automated Demand Response Systems

Pros and cons exist for different DR
implementation methods
Manual Methods Automated Systems
• Increased reliability
• No financial outlay for
equipment • Some can “dial down” duty
Pros Pros cycles
• Should have auditing and
reporting capabilities
• Relies on the human
component  vulnerable to
distractions, error
• Electrical loads are either On
or Off  No “dialling down”
Cons duty cycles Cons • Easy to get wrapped up in
“nice to haves”  Expense
• DR times can be unpredictable
 disruptions to people’s
schedules
• Difficult to gather reporting

Real-Time Control and Reporting down to the level
of each load is a “must have” to confirm activity
Critical for successful DR testing, event confirmation
IP “edge devices” simplify making the invisible… visible!

From Theory to Practice: Consumers are more likely
to accept DR if it is simple, quiet, unobtrusive
Top 3 consuming load types
• HVAC
• Lighting
• Refrigeration
Principles to Shed by:
• HVAC easiest to shed to avoid noticeable disruption
• Avoid thermostat setbacks that can induce unnecessarily high peaks
• Occupant comfort can be reasonably maintained if “dialing down” duty cycles

Specific lessons from case study
Implementation costs – and
benefits can vary dramatically
by type of load
Baseline
Real-time control and
DR verification of DR activity is key
Invasive DR causes negative
occupant reactions
Swarm load-balancing less
invasive than thermostat
