6. The Growing PEV Market

7. Why Install Workplace Charging? Recruit and retain employees Green your image Improved commute – increased employee productivity Help comply with local air quality and transportation policies LEED points toward certification

8. Key Considerations Review key workplace charging resources Plan for growth – Survey employees to determine current and future interest in PEVs Establish internal procedures – Level of access, payment options, etiquette Dedicate staff – An employee is usually needed to manage the chargers and employee use Contact local utility and landlord or facilities manager to evaluate charging

16. San Diego EV Stats: As of October 1, 2014 : – Over 11,000 electric vehicles on the road – Over 650 Level 2 commercial charging stations in service – 28 DC Fast Chargers in service 16

17. Plug-in Electric Vehicle Charging Home Single Family Residences Multi-unit Dwellings Workplace Public

18. Workplace Charging Overview – Small amount in region - we’d like to increase it – Other than home, EVs are parked longest at work – Provides PHEV drivers a way to drive more electric miles – Allows BEV drivers to commute longer distances successfully – Benefits EV drivers that don’t have access to home charging 18

19. Equipment Selection – Level 1 Level 1 (120v, usually at 1.4 kW) – Typically adds 4-6 miles of range per hour – Most cars come with AC Level 1 cord set – Will run on standard 15 amp circuit – Advantage: Can be used anywhere – Disadvantage: Slower charging – Grid Impact: Mild

20. Equipment Selection – Level 2 Level 2 (208-240v at 3.7 kW, 7.2 kW, 9.6 kW, & 19.2 kW) – Most 2011-2012 cars using Level 2 draw 3.7 kW – Many newer models will draw 7.2 kW (2013+) – Needs a dedicated 208-240v circuit – Advantage: Faster Charging – Disadvantage: Higher Cost – Grid Impact: Moderate

21. Power Sources for EV Charging Existing Electric Panels : – Usually cheapest solution – Spare capacity is usually minimal – Expensive to expand – Minimal utility involvement New Electric Service : – Forward thinking; location freedom – Separate billing (3 rd parties) – More capacity – Makes sense for large charging loads

22. Workplace Charging Questions: How many employee cars now? How many expected in future? How many charging stations are you thinking of? Is there a budget? Is available power nearby? 22

23. Site Selection: – Power Source New Electric Service Existing Panel (Capacity) Transformer proximity Trenching Existing Panel – Parking ADA Requirements “Making a Green Statement” by front door or choosing least cost Balance power availability vs. parking convenience Move Cords Not Cars Reserving Spots Striping and Signage 23

24. EV Charging Project Guidance: – Typical EV Charging Project Consult with utility on electrical requirements – New service, RFS Form – Existing Panel RFP Process (if applicable) Hire engineering firm to design project – Electrical / ADA requirements Hire contractor to build project Procure equipment & materials Get permits Construction takes place Approvals / Testing / Commission Misc. issues – Parking Policies for employees – Billing EV drivers 24

25. SDG&E Information – Electric Rates Commercial “A” Rate Commercial “AL-TOU” Rate Residential “EV-TOU” Rate Residential “EV-TOU2” Rate – SDG&E Services for EV / Workplace Charging Site Visits (Clean Transportation) Consultation (Clean Transportation) Internal SDG&E Referrals (Clean Transportation) New Service Assistance (Project Management)

26. SDG&E Workplace Charging Case Study – (Total) 51 Chargers at 15 locations – (Century Park) 26 Chargers total – 10 Chargers are on internal pilot program “Vehicle Grid Integration” or VGI program Two Level 2 and Eight Level 1 units Hourly Pricing: CAISO + retail adders + peak ckt loading adder Charging sessions managed at kiosk or via web or phone app Employees set kWh needed, max price, departure time Managed charging benefits
