My intention with this thread to is offer confirmed (evidence based) information on existing and new supercharger locations in the Northeast AS WELL AS TO offer encouragement to Tesla to remedy the dearth of SuperChargers in the region. This is a huge and relatively compact market for Tesla: the population of the Northeast is 56 million, 18% of the total USA. Yet, the population centers of Boston, Hartford, and Philadelphia are inadequately connected -- and links to Montreal and Toronto are completely missing.
Just 4 new superchargers will do this:
Sturbridge, MA (should be a no-brainer)
Edison, NJ (which is underway)
Albany, NY (who knows what is going on there)
Canandaigua, NY (midway between Albany and Toronto) (This would also serve Buffalo and Rochester)
High payoff for 4 new SuperChargers (one of which is underway, so really 3). How 'bout it, Tesla?
UPDATE: 07/17/2014: if you add the population of Quebec and Ontario, this area is home to 77 million people. But much of the area remains WAY under served. Grateful for Tesla Motors recent post that the Quebec to Toronto corrodor is scheduled for Superchargers but this needs to be connected to the 95 corridor. When complete, a potential market of 77 million people will have access.
