  2. 2. © 2009 REGEN Energy Inc What is Demand Response? • Management of electrical consumption • Active alleviation of grid stress • Load Shedding during peak demand periods Demand Controlled Decreased Response Load Grid Stress Financial Shedding / Incentives Balancing
  3. 3. © 2009 REGEN Energy Inc 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! Source: Schneider Electric and Peter Schwartz & Associates 2008
  4. 4. © 2009 REGEN Energy Inc 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 PG&E Rates and Incentive Demand Rate $10-12/KW Demand Response $200-$250/KW Incentive
  5. 5. © 2009 REGEN Energy Inc Developing a Comprehensive Energy Strategy is useful for all corporations, well beyond DR alone Energy Demand Efficiency Management Demand Alternate Response Energy
  6. 6. © 2009 REGEN Energy Inc 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
  7. 7. © 2009 REGEN Energy Inc 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
  8. 8. © 2009 REGEN Energy Inc 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!
  9. 9. © 2009 REGEN Energy Inc 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
  10. 10. © 2009 REGEN Energy Inc Case Study of a Wireless DR Installation HVAC Units REGEN Controllers HVAC, DHW, Lighting Monitoring and controlling Rooftop HVAC units loads in an office building REGEN Communications Gateway EnviroGrid™ controllers REGEN Controllers Monitoring and controlling use swarm logic to reduce hot water tanks Hot water tanks and smooth demand HTTP Web browser Lighting Monitor loads, REGEN Control Centre REGEN Controllers invoke DR Control Application Server and Data Storage HTTP monitoring lighting loads Integrated IP-based reporting and DR control Lighting Control Server 7x24 Peak DM as an Wired Connection additional benefit even Wireless Connection when DR not invoked HTTP Connection
  11. 11. © 2009 REGEN Energy Inc 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 setbacks IP-based connectivity simplifies & reduces implementation costs
  12. 12. © 2009 REGEN Energy Inc REGEN EnviroGrid™ For Smart Grid • 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.

  13. 13. © 2009 REGEN Energy Inc Using a ZigBee mesh network, and REGEN’s patented methodology, controllers communicate EnviroGrid and cooperate the same way swarms do. Server HVAC Communication takes place between all units every 2 minutes EnviroGrid Lighting Web 2.0 APIs Commercial All units can be controlled and Optional modem allows for two way communication Pumps monitored through the over the Internet. Power EnviroGrid Portal Each controller readings are sent without makes a the need for a local decision every computer or BAS/EMS 15 minutes based on the total collective info to ensure most efficient use of energy Heating EnviroGrid Customer Portal
  14. 14. © 2009 REGEN Energy Inc 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
