> Electricity is also quite expensive. I did the math on my PHEV - and even if I only charge overnight when electricity rates are lowest, I don't save very much over using gasoline
I'm curious how the math would work out with an all-denka plan. I work from home so I switched from an electric plan where during daylight solar hours my electricity drops to 13 yen/kWh
¥13/kWh is a very good rate. Does that include fuel adjustment and renewable energy surcharge?
My current overnight rate is about ¥21/kWh after factoring in those adjustments - so yes if I could charge at ¥13/kWh that would be a sigicant difference. I'm not aware of any providers that offer that rate in my region, though (electricity here tends to be more expensive than the national average).
I actually reran my calculations and it looks like running my car on electricity is about 40% less expensive per km than gasoline, which is better than I expected. While that's significant if I'm just looking at fuel costs, it's not that significant when I look at total cost of ownership. And I do expect electricity to have less of an advantage in winter, when waste heat from combustion can be used to heat the car.
