The reason is not efficiency, but rather population density. Supply power to a rural town of 5,000 in Kansas means stringing miles of high tension cables from one distribution center to the next and dividing those cost over a relatively small number of customers. However, stringing the same number of miles of cable in NY can be spread over tens of thousands of customers. Such crap is from Chapter 1 of Huff's How to Lie With Statistics.
