Yes, And then theres free charging from your rooftop solar.   
Heres the info sheet I display on my E-Landy when I take it to shows.  On petrol it cost  about $27.00 per 100km 
I have not paid a cent for electricity in 5000km  but If I didn't have Solar (Lets face it you would be nuts not to if you have an EV) , If I was paying AGL retail rates for my power  100km would cost me about $7.50
Its just a guesstimation based on the claimed KWH size of my battery back,  I've just ordered a KWH meter which I'll install on my car & be able to quote exact figures soon.
