Power Grid Infrastructure 50 to 100 years oldForecasted growth way under estimatedDid not anticipate new electronicsComputersAir ConditionersGame BoysTelevisions Cell Phone ChargersPassive DrainCell Phone chargers, TVs, Microwave, DVDsCell Phone chargers (not charging phone) consume over 900,000 Mw-hours/year Why do we need Demand Response?
Grid Overloaded during Summer MonthsPower consumption continues to grow over 2% per yearReduce burning fossil fuels, and generating greenhouse gasses Eliminate Spinning ReserveWhy do we need Demand Response?
Power can be disrupted during SummerGeneral public does not understand shortage of power Large commercial and industrial users consume 70% of powerCommercial and industrial users have not understood their role in power managementHave the ability to mitigate rolling blackoutsResidential customers are at work or school
General Public Un-informed
Without demand response CAISO does not have enough control of gridRolling blackouts are still a threat Large consumers can change rolling blackout risks
Commercial and Industrial
Three methods that help power consumption and generationEfficiencyCFL, high efficiency A/C ect.WindGenerates non-polluting clean energy Out of sequence with peak demandSolarBest method that helps peak reductionCan these methods keep up with 2% growth in power consumption?Solar, Wind, Efficiency?Building new power plants is not an option3% to 7% of the year there is a problem on the GridNo problem in October, small time during summerNot feasibleCostPollutionTransmission linesCostPermitsWe need to better manage our gridEnergy act 2005
Build New Infrastructure?

User selected LoadsCritical and Non-criticalIf CAISO calls Stage 2 Emergency Mica-Tech system sends signal to user Energy Management System EMS to reduce selectedPre-coolingCAISO will notify day ahead warning Set Thermostat 2 deg cooler prior to event
How Does it Work?
One Event per Day4 hours maximumWill not exceed 120 hours per year
Power Grid System Security and ReliabilityTransmission SubstationHighest level of SCADA Power Grid Control2000 and 2001 Rolling blackouts Utilized Mica-Tech Network (over 20,000 Mw)Single Largest Demand Response Action with Mica-Tech equipmentWhy Mica-Tech?
