I know Tesla has said that Supercharging Revenue would be used to pay for the cost of supercharging. Obviously a lot of M3 owners need to "fill up" in order to cover the cost for the energy for S and X owners. But now that Tesla is doing away with free super charging for life, and at the same time adding 300,000+ M3 per year, it got me thinking. How much revenue is it generating. I have had a M3 for 7 months and have paid $84 for Tesla super charging. I drive a lot, but so do most Tesla owners. So that works out to roughly $150 per year. So we are taking about $15 million per year per 100,000 cars that are paying for supercharging. So we could easily see Tesla with 20-30 million in 2019 supercharging revenue. I would think that the cost of adding a super charger is not too much(if anyone has an idea please let me know). But 20-30 million sure does pay for a lot of electricity and probably some expansion. And this number will grow exponentially as they continue to add cars to the road and superchargers to more locations.
