Demand ResponseMay 9, 2008
![Page 2: University California Santa Barbara](https://reader035.vdocuments.mx/reader035/viewer/2022062302/5681694e550346895de0ef33/html5/thumbnails/2.jpg)
United States◦ 40 Million People◦ 8 States
Canada◦ 10 Million People◦ 7 Provinces
Cost $6.0 to 10.0 Billion
North East Blackout 2003

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
Why do we need Demand Response?
![Page 4: University California Santa Barbara](https://reader035.vdocuments.mx/reader035/viewer/2022062302/5681694e550346895de0ef33/html5/thumbnails/4.jpg)
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
Why do we need Demand Response?
![Page 5: University California Santa Barbara](https://reader035.vdocuments.mx/reader035/viewer/2022062302/5681694e550346895de0ef33/html5/thumbnails/5.jpg)
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
General Public Un-informed

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

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?
Solar, Wind, Efficiency?

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
Build New Infrastructure?
![Page 9: University California Santa Barbara](https://reader035.vdocuments.mx/reader035/viewer/2022062302/5681694e550346895de0ef33/html5/thumbnails/9.jpg)
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
What is Demand Response?
![Page 10: University California Santa Barbara](https://reader035.vdocuments.mx/reader035/viewer/2022062302/5681694e550346895de0ef33/html5/thumbnails/10.jpg)
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
How Does it Work?
![Page 11: University California Santa Barbara](https://reader035.vdocuments.mx/reader035/viewer/2022062302/5681694e550346895de0ef33/html5/thumbnails/11.jpg)
One Event per Day 4 hours maximum Will not exceed 120 hours per year
How Often?

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
Why Mica-Tech?

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)
Mica-Tech Inc.

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
Why Mica-Tech?

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
Demand Response Water?
