I may be too conservative in my estimates. It's easy to assume 75 GWh production for Tesla Energy at the Gigafactory before 2020 at 400 USD/kWh and 30% margin, leading to the conclusion 30 billion revenue and 9 billion in gross profit. It may be accurate, I don't know.
But there are some reasons why I'm a bit conservative:
- There is a lot of competition for TE. Currently Tesla has a massive lead when it comes to cost, but I expect this advantage to erode over time. BYD and others won't let Tesla take the market unopposed.
- 400 USD/kWh is fine for the current volume, but going from a few hundred MWh per year to tens of GWh per year, I think Tesla needs to offer more compelling pricing.
- In the short term (~2 years), I think the vehicles will absorb most of the Gigafactory output. Now, if the Model 3 becomes delayed, Tesla should have sufficient capacity to really focus on Tesla Energy, but I tend to think Tesla is not that far out of the ballpark with Model 3 production plans. (TE is really nice for derisking the Gigafactory, though.)
I would like to see Tesla start up Gigafactory phase three construction this year. This should bring a lot of TE revenue closer than my estimated 2019-2020 time frame. It would also allow Tesla to take greater advantage of thir current position in the market, and prevent their advantage from eroding as much.
I am very appreciative of your analysis -- I think it is very helpful.
I do think it is fascinating that even relatively conservative estimates regarding production and margin/earnings lead to SP guidance of $555-$736 in 2018/19, even assuming a P/E of 20 -- which is extremely low for a company growing at 50+% per year.
