2011 PEV Customers

• Estimate 1,200 PEVs on road by year end 2011

• Of those signed up for EV Project & experimental PEV

Rate Study (separately metered)

– 47% vs 19% (all SDG&E customers) higher income

– 35% are PV customers (vs. 1.1% of all SDG&E customers)

– About 8 kWh (25 miles) average use per day

– 84% charge between midnight & 5am

• Nissan Leaf “hand hand raisers” raisers – profiles the next PEV buyer

– Are cost-savings cost savings focused

– Want convenience

– Have “green green” interests

��Smart Smart grid technology meets these needs

SGDP PEV Projects

• PEV Rate Study – impact of TOU pricing on charging time decisions

– If pricing effects charging time, then smart grid technology is a must

• Efficient integration of PEV charging loads with the grid

– Flexible Demand Initiative – integrated battery, PV & EVSE demo

– Transformer monitoring – laying foundation for smart transformers

– PEV load signature detection program

– Support EVSPs product & service development

• EV Project support – deployment of residential & commercial EVSE

• Workplace charging – level 1 & 2 EVSE “smart smart” options

• Metrics – kWh use per PEV & kW load shifting persistence


What Drives Charging Time Decisions?

PEV Rates & Technology Study – CPUC approved experimental PEV

rates for EV Project & Nissan deployment

• Price – Large $ Savings?

Low super off-peak off peak rates

• Technology & Information

– “Set Set & Forget”? Forget

On-board On board Leaf technology

• Convenience & Lifestyle –

Do Travel Needs Rule?

TOU Rate is Effective Regardless of Price


Efficient Integration with the Grid

Flexible Demand Initiative – integrated battery, PV & charging demo

• Stage setting for G2V (DR) and V2G applications when OEMs are ready ready

• Meets CAISO needs in ancillary service market – create & demonstrate

controls & communications technology needed for regulation services services


Are education / outreach and

time-variant time variant rates enough?

Is additional smart grid load

management enabling

automation needed to

reduce charging impacts

from PEV clustering?

– Understanding of charging

impacts on system

– Persistence of super off-peak off peak

charging behavior

What else …

SDG&E Connected…..to Connected ..to electric vehicles

www.SDGE.COM/CleanTransportation

• Push to SDG&E & other Clean Transportation Web

resources (e.g., GoElectricDrive.com)

• Getting the word out about the benefits of PEV rates

• Working with dealerships & community PEV events

• Targeted communications & workshops

• Contractor & Inspector Training/Forums

• Is there a need for independent EVSE turnkey “operators operators”
