In the US don't forget there is a 'transmission charge' also. Here in the wonderful state of NJ, it is $0.12 Kwh. Now add the $0.067 transmission charge for a marvelous total of $0.187 Kwh.
I was wondering this too.. final bill price can be much bloated
here in PA it is an honest .15kW/h total
Whoa... Is that PECO?
