I'm in Central PA, but have an archaic Municipal Power Company (our town IS the power company), so don't have TOU rates. Our rates go down as you use more power, so it's actually really stupid and counter-productive from a base load standpoint, but they buy huge blocks of energy from AMP Ohio, and can make a profit by buying low in bulk, selling high to consumers.
That said, it still only costs me about $2 (16kw*0.13/kwh) to charge up the i, and that takes me 60 miles ... so that's like getting $1/gallon gasoline. So it's really the high initial costs, not the day to day per mile costs, that are hard for EV owners to bear and why more people aren't buying them. I'm sure if the i was only $15k or less out of pocket, they'd sell a lot more of them.
