Anyone have an estimate of how many KWh the SCs provide annually?

    I was just thinking about how much the annual electricity bill is for Tesla - US and/or worldwide.
    Anyone have a swag? I realize that the vast majority will now be paying their own way in the future.

    I'll take a rough estimate and invite others to throw darts at it.

    Say 250,000 cars with free supercharging.

    12,000 miles per year on average.

    15% of that via superchargers = 1800 miles per year via SC stations

    So that would be 0.25x10^6 * 1.8x10^3 = 0.45 billion miles = 450 million miles
    at 3 miles per KWh, that is 150,000,000 KWh (150 Million KWh)

    at 10 to 20 cents per KWh, that turns out to be 15 to 30 Million dollars per year.
    Or one small drop in the bucket.

    Today there are about 1300 SC sites around the world.
    I wonder what the property taxes are for those sites, or if the businesses near the site pay for the property taxes?

    Anyway, seems that the electricity bill should be in the 50 million per year range by the above rough calculation.

    So let the fine tuning begin.

    It’s impossible to get even a ballpark estimate because Elon Musk mentioned how some sites pay for the electricity, how many sites? No one knows.
    Therefore math can’t really be done to figure it out

    I also wouldn’t call 30 million a drop in the bucket for a cash strapped company

    And let's not forget Tesla is ramping up the number of cars big time.

    I wonder where these costs appear in the quarterly reporting? Marketing costs? Elsewhere in SGA?

    Free for all - forever would just not be sustainable.

    It would not be fair either. Why should the heavy users be subsidized by the other?

    Aren't the majority of cars now being sold with only 400 KWh free per year (model S only - or does that include model 3?) or something like that? That is only $40-$100 per year.
