Tesla drivers in other parts have the country; specifically California, have a more advanced super charger network and generally better climates for maximizing range per charge. I've found quite a bit of information on electricity costs for these drivers but not much information from New England drivers. Does anyone keep detailed stats on how much the Model S has increased their electricity costs? If you could include the miles you typically drive and your cost per kwh that would be extremely helpful to my research. I think my rate is somewhere around $.21/kwh, $.13 delivery/$.08 supplier. I anticipate that electricity will cost me about 40% of what gasoline costs me on a monthly basis.
