The case for plug-in electric vehicles
> Net reduction in greenhouse gas emissions
> Reduced petroleum dependency
> Lower fuel cost for consumers
> Economic development and industry leadership opportunities in an emerging industry
Benefits come only with mass market acceptance of electric vehicles
3
The local utilities are collaborating and have formed the Regional Electric Vehicle Initiative (REVI)
4
The REVI utilities working group has operations in 5 states
Northeast Utilities (CT, MA & NH)
National Grid (MA, NH, NY & RI)
NSTAR (MA)
United Illuminating (CT)
Municipal utilities (CT & MA)

Home installations could be lengthy, complicated and a potential source of consumer dissatisfaction
› Installation times varied between 22 and 38 days during recent vehicle pilots
Many businesses have an interest in providing charging station availability to their customers.
› Plug-in hybrids may need less away-from-home charging locations than Battery Electric Vehicles
1 station per vehicle
1 station per 1,000+ vehicles?
1 station per 10 - 100 vehicles?
Occupies the imagination and energy of the policy dialogue, but not critical to the early adopter stage (McKinsey and TEPCO Studies)
› The challenge is to develop an appropriately sized away-from-home infrastructure (too much can be as bad as too little)
70 to 80% of the Charging

Commoditizing EV chargers is a good thing for the overall electric vehicle industry

Can the utility system accommodate EV charging?> Yes, the bulk electric supply system can generally meet the demand - Rule of thumb: A 5%
penetration rate of EVs increases total kWh volume by less than 1%
> There is some potential for local distribution issues depending upon various of factors
> Policies needed to promote overnight / off-peak charging for minimum impact on the utility system
What are the utility regulatory issues to address?
