This is from the following source:

Kintner-Meyer, M., K. Schneider, and R. Pratt. 2007. Impacts Assessment 
of Plug-in Hybrid Vehicles on Electric Utilities and Regional U.S. Power 
Grids. Part I. Technical Analysis. Paper presented at the 2007 Electric 
Utilities Environmental Conference, Tucson, AZ, January 21-24, 2007.

... which actually quotes the values from another set of papers by the 
Electric Power Research Institute.

The authors are from Pacific Northwest National Laboratory. Sounds like 
Roy beats them out on this. Maybe that has something to do with not 
having the ICE as extra weight. Note the "PHEV33" means enough battery 
storage to go 33 miles. The basic result from this paper was that by 
using off-peak electricity to charge PHEVs, you could charge 73% of the 
light duty vehicle (LDV) fleet (cars, SUVs, and light trucks) of the 
U.S. without building any new power plants or power lines. This offsets 
6.5 million barrels of oil. Of course, that is IF you time the charging 
almost perfectly. A more modest assumption on the timing of charging 
vehicles at night (only from 6 pm to 6 am) resulted in 43% of the LDV.
