  1. University California Santa Barbara Demand Response May 9, 2008

  2. North East Blackout 2003 • United States • 40 Million People • 8 States • Canada • 10 Million People • 7 Provinces • Cost $6.0 to 10.0 Billion

  3. Why do we need Demand Response? • Power Grid Infrastructure 50 to 100 years old • Forecasted growth way under estimated • Did not anticipate new electronics • Computers • Air Conditioners • Game Boys • Televisions • Cell Phone Chargers • Passive Drain • Cell Phone chargers, TV’s, Microwave, DVDs • Cell Phone chargers (not charging phone) consume over 900,000 Mw-hours/year

  4. Why do we need Demand Response? • Grid Overloaded during Summer Months • Power consumption continues to grow over 2% per year • Reduce burning fossil fuels, and generating greenhouse gasses • Eliminate Spinning Reserve

  5. General Public Un-informed • Power can be disrupted during Summer • General public does not understand shortage of power • Large commercial and industrial users consume 70% of power • Commercial and industrial users have not understood their role in power management • Have the ability to mitigate rolling blackouts • Residential customers are at work or school

  6. Commercial and Industrial • Without demand response CAISO does not have enough control of grid • Rolling blackouts are still a threat • Large consumers can change rolling blackout risks

  7. Solar, Wind, Efficiency? • Three methods that help power consumption and generation • Efficiency • CFL, high efficiency A/C ect. • Wind • Generates non-polluting clean energy • Out of sequence with peak demand • Solar • Best method that helps peak reduction • Can these methods keep up with 2% growth in power consumption?

  8. Build New Infrastructure? • Building new power plants is not an option • 3% to 7% of the year there is a problem on the Grid • No problem in October, small time during summer • Not feasible • Cost • Pollution • Transmission lines • Cost • Permits • We need to better manage our grid • Energy act 2005

  9. What is Demand Response? • Reduce energy costs • Curtail interruptible load at peak price • User Selected • Air Conditioners • Lights • Non-critical machines, pool pumps ect • Critical Loads are not affected • Computers/Servers • Inner area lights • Ventilation

  10. How Does it Work? • User selected Loads • Critical and Non-critical • If CAISO calls Stage 2 Emergency • Mica-Tech system sends signal to user Energy Management System EMS to reduce selected • Pre-cooling • CAISO will notify day ahead warning • Set Thermostat 2 deg cooler prior to event

  11. How Often? • One Event per Day • 4 hours maximum • Will not exceed 120 hours per year

  12. Why Mica-Tech? • Power Grid System Security and Reliability • Transmission Substation • Highest level of SCADA Power Grid Control • 2000 and 2001 Rolling blackouts • Utilized Mica-Tech Network (over 20,000 Mw) • Single Largest Demand Response Action with Mica-Tech equipment

  13. Mica-Tech Inc. • SCADA-Supervisory Control and Data Acquisition • 50,000 Sq Mi territory Southern California • Wyoming, Colorado, New Mexico, Nebraska and Arizona • Over 10 years live grid • Reliable and Secure • Transmission Substations and Hydro sites (Dams)

  14. Why Mica-Tech? • Secure not internet based • CIA: Hackers to Blame for Power Outages • Hackers literally turned out the lights in multiple cities after breaking into electrical utilities and demanding extortion payments before disrupting the power, a senior CIA analyst told utility engineers at a trade conference. • Bank hack attacks up 81% • Mica-Tech System private satellite network • Over 10 years cannot be hacked • Demand Response should not put operations at risk • CAISO has been hacked • CAISO/Mica-Tech Joint Project

  15. Program Details • No Cost- Installation and Management Technical Assistance • No Training of Personal -fully automatic • No Penalties • Cash incentive

  16. Demand Response Water? • Could work to cut usage just like power • Where? • Pump water back over dam • Farms not economically feasible crops die • Lawns? Yes • Limit use • Schedule best time to water • Cut use entirely
