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
PG&E Rates and Incentive
Demand Rate $10-12/KW
Demand Response Incentive
$200-$250/KW
• 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
• Easy
• Simple
• Reliable
Demand Response Should Be:
Demand Response Implementation:
• Manual Demand Response Actions
• Automated Demand Response Systems

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

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

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

EnviroGrid™ controllers use swarm logic to reduce and smooth demand
Integrated IP-based reporting and DR control
7x24 Peak DM as an additional benefit even when DR not invoked

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

REGEN EnviroGrid™ For Smart Grid
HeatingHVAC Cooling InformationLighting
• EnviroGrid™ delivers automated, command and control of cooling, heating and lighting edge devices using SWARM logic
• Intelligent, adaptive management and on going measurement of environmental edge devices using a non-intrusive comfort neutral approach.
• Reduce CAPEX and OPEX by curbing peak demand and enabling demand response for more efficient use of energy loads.

Using a ZigBee mesh network, and REGEN’s patented methodology, controllers communicate and cooperate the same way swarms do.
Each controller makes a decision every 15 minutes based on the total collective info to ensure most efficient use of energy
Optional modem allows for two way communication over the Internet. Power readings are sent without the need for a local computer or BAS/EMS
Communication takes place between all units every 2 minutes
All units can be controlled and monitored through the EnviroGrid Portal

EnviroGrid™ captures the simplicity and features that drive customer DR acceptance
Easy, fast to deploy in an entire facility in hours
Patent-pending swarm logic methods reduce demand, not comfort
Provides full real-time control and reporting to confirm DR activity
Automated DR capabilities without the need for complex operator training and monitoring
