UPS, the major delivery chain, has two all electric vehicles operating in New York City. You can spot the difference because there is no radiator grille on the front, and the side panel says "Zero Emission Electric Vehicle." When the truck's drivers was asked about the truck, he said it had a 15 mile range. AutoblogGreen has a few pictures of the truck, including the front and side panels. No more details are available right now as to if this program will be expanding.
