No tailpipe so no emissions Electricity is a low cost fuel Consumers love them Why Electric Vehicles?

The first generation of cars, coming in the next 3 years, take 4 hours to charge Cars are parked somewhere 23 hours a day – that’s where we need charging stations  In homes, apartments, condominiums and hotel garages  In workplace parking lots  In public lots and curbside  In San Francisco there are 6 times as many cars as private garages Where Do We Fuel Them?

Why do we need Smart Charging? To generate the revenue needed to pay for electricity, charging stations, station maintenance, road maintenance taxes, and real estate To make the grid efficient and dependable To make life easy for EV Drivers To keep life cycle costs low

Policy Needs For a Successful Industry 1. Enable workable revenue model for shared stations (apartments, condos, public, retail, workplace) o Drivers need to pay station owners for electricity, maintenance, capital, and real estate 2. Enable incentive rates and integrated metering o Incentive pricing requires some type of submetering o We can include submetering in the charging stations at very low cost o Incentive pricing encourages people to use off-peak energy o This will ensure that the grid is used efficiently 3. Smart Grid Integration o Charging stations with Demand Response, Time-of-Use Pricing, and AMI will be compatible with the modern electric grid 4. Help with Local Planning o We need public charging locations o Streamline installation permitting and inspections
