Not that I have really looked hard, but I don't recall seeing electrical outlets in any parking stall I have ever used. I know there are none in the parking lot for my apartment.
If we are sharing anecdotes: both my condo building and office building have reserved spots for charging electric cars. However, I'm not a fan because they were both installe by government subsidy and currently offer free power. Just why we need: to subsidize the drivin habits of people rich enough to afford an electric car (as they currently command a price premium).
Where I live electrical outlets are quite common because many people use enging heaters during the winter. Also, the government has sponsored many free parking spots with charging (although the free part will probably disappear as soon as electrical cars get popular).
