  1. Plug-In Cars: Enhancing Smart Grid Investment Returns Steven E. Letendre, PhD Associate Professor Green Mountain College Poultney, VT May 19, 2010 REV DG Conference 2010 Manchester, VT

  2. Coming to a showroom near you…?

  3. What we know? • Plug-in cars dramatically improve fuel economy • Initial vehicle launch (GMC and Nissan) later this year with MSRP well north of $30K. • Lithium Ion batteries (Leaf 24 kWh / Volt 16 kWh ). • Agreement on plug (SAE J1772) 3-point 400V. • There is sufficient off-peak capacity nation-wide to charge a large number of plug-in cars. • Electricity is a less expensive fuel for cars than gasoline on a per mile basis. • Federal incentives are key driver, up to $7,500 per car.

  4. What we don’t know? • How robust will the battery packs be and will they require replacement at some point during the life of the vehicle? • Consumer charging preferences? • Which companies will dominate the smart charging and vehicle management IT space? • How quickly will consumers adopt plug-in cars? • What will the fleet of plug-in cars look like 5, 10, 20, 30 years out?

  10. It’s Happening Now ($120 - $200 / month / vehicle)

  11. V2G Resource in Vermont: Projections Aggregate Energy Storage Potential of Plug-In Fleet (MWh)

  12. V2G Resource in Vermont: Projections Aggregate Power Output Potential of Plug-In Fleet (MW)

  13. Smart Grids to Link RE Production with Plug-In Car Charging

  14. Concluding Thoughts • Plug-in cars represent a large new load for households and the power system. • Smart grid technology can serve to: manage vehicle charging, unlock V2G revenues, and link RE production with vehicle charging. • It may take a decade to see large numbers of plug-in cars in Vermont, but meaningful demonstrations can happen (should happen) much sooner. • Smart grid technologies can generate significant value creating a bridge between the electric system and the auto fleet.
