My electricity bill in Massachusetts is divided into two parts - elecricity supply charge and delivery services charge. Each costs about 10 cents per kWh, for a total cost of 20 cents per kWh.
At 325 Wh/mile, and assuming a 10% efficency loss I need 536 kWh to cover 1500 miles in my model 3, costing me $107.
My acura TSX gave me 26 miles per gallon, which translates to $133 to cover the same distance at current fuel prices.
This is less than $30 savings for me per month. This is much less than the savings I was expecting. Am I missing something?
I was curious to know if this is consistent/similar for other Tesla owners in Massachusetts.
