2 About Southern California Edison Largest electric utility in California Peak load 23,300 MW (2007) 4.6 million customers Serving central, coastal and southern (50,000 sq. miles) PG&E Peak load growth higher than energy growth Increasing costs to serve peak load 24,000 22,000 Peak Load Growth 61% 59% LADWP SCE SDG&E MW 20,000 57% 55% 18,000 53% 16,000 51% MW Demand Load Factor 2

3 SCE s Demand Response Program Portfolio Today s portfolio includes over 1,600 MWs of dispatchable load: Emergency programs: Customers reduce load when triggered by a system emergency to contractually determined levels in exchange for an incentive, usually a bill discount on an annual basis Emergency Programs MW Large Commercial Interruptible Residential/commercial air conditioning cycling Agricultural pumping interruptible Price response programs: Customers reduce load at critical times based on dynamic pricing of energy and/or capacity ( pay-forperformance ) Price Response Programs MW Critical Peak Pricing/RTP Rates Demand Bidding Capacity Bidding Aggregator Contracts 3

4 Impact of Demand Response 22,200 22,000 21,800 SCE Demand Response Reduces the Peak Projected load growth DR Impact System Peaks ,136 MW ,762 MW ,934 MW ,889 MW ,303 MW ,020 MW SCE Load (MW W) 21,600 21,400 21,200 21,000 Actual load 20,800 20,600 20,400 The SCE system peak was shaved when demand response programs were activated: SDP, EST, Cal DRP, DBP and EST (about 350 MW MW) 12:59:03 13:19:04 13:39:02 13:59:03 14:19:04 14:39:03 14:59:03 15:19:04 15:39:04 15:59:04 July 22 (1pm to 4pm) 4

5 Edison SmartConnect Enables SCE to Evolve its DMS Portfolio Between 2009 and 2012, SCE plans to replace more than 5 million meters on all SCE s small commercial and residential customers < 200 kw 200A service switch with load limiting capability Remote upgradeability Integrated HAN interface (ZigBee) Integrated 2-way LAN communication Power quality metrics Robust security New metering will enable collection of interval usage data Hourly intervals for Residential 15 minute intervals for Commercial 5

6 Empowering Customers with New Offerings Customers will have new choices to manage costs and peak demand. Residential Small Business Single Family Multi Family 1 kw 20 kw Peak Time Rebate Thermostat / Energy Display Device Programs Critical Peak Pricing Time Of Use Interval Data Programs Critical Peak Pricing Time of Use Thermostats Energy Display Device Programs Interval Data Programs Reduce Peak Load by 1,000 MWs Energy Conservation - 1% minimum Reduce GHG by 1,000 tons/day Medium Business 20 kw 200 kw Chains & Other Critical Peak Pricing Time of Use Thermostats Energy Display Device Programs Interval Data Programs 6

7 Communication Channels For Customer Information Hourly Interval Data Collected Daily Real-Time Instantaneous Demand Information SmartConnect Metered Home Back-office (Data Processing) Previous Day Hourly Interval Usage Data Available 7

8 ZigBee A Key Enabler for New and Future Offerings In-Home Display Concepts Control Application Concepts Thumb Drive Energy Usage Display Price Indicator Refrigerator Magnet Home Automation AC Load Switch Pool Pumps PCTs PDAs Communications equipped smart appliances Plug-in Outlet appliance switches Control Application Concepts 9 10 Communicating electronic ballasts Communicating / dimmable light switches 11 Communications equipped circuit breakers Many concepts in various states of progress 8

9 ZigBee Enabled In-Home Display Concepts 1 2 Customers can connect their PC to the ZigBee meter interface to receive near real time information Customers who have utility-registered inhome graphical display units can qualify for additional incentives if they reduce usage during critical peak events 3 Peak Rebate Available Energy Cost Display $.12 $.14 $.24 $.27 $.31 Customers can determine if there is a critical peak event scheduled or in progress. They can also see how much they are paying for electricity. 9
