I've been thinking about Tesla Energy lately, especially how disappointed I am with regards to Tesla Energy. I'm thinking that Tesla Energy is completely a de-risk maneuver. In 2013, when Tesla went to Panasonic to re-negotiate their supplier agreement and order up something north of 8 GWh of production a year, Panasonic probably thought they were nuts. After all, Panasonic was bleeding red ink and had bled lots of red ink as battery demand did not materialize. They had abandoned the 2nd phase of the Suminoe plant and shuttered other facilities. Now Musk comes and insists they want more batteries. Remember, in the summer of 2013, as much as Tesla stock had soared, the actual volume of vehicles at that point wasn't all that impressive. On top of that, Tesla wanted Panasonic to cough up another $2 billion or so and build the world's biggest battery plant? Right after Panasonic had to shut down plants and drop expansion plans because of lack of demand?
So, I think Musk had to commit to selling those cells regardless of how Tesla vehicles did in the marketplace. Not only that, they were creating a new battery plant that would effectively obsolete the very plants in Osaka, Japan that Tesla wanted Panasonic to dump some money into in 2013/2014/2015 to build more cells for Tesla. Hmmm... so I think Tesla Energy is a result of Musk promising that all will turn out well for Panasonic.
As a result, I think Tesla Energy only gets cell supply that Tesla Automotive can't sell. And in 2015, that's primarily the result of the Model X delay. Say Panasonic had to make production plans in 2014 for the amount of cells they were going to build in 2015 for Tesla. Tesla tells them that the Model X will ship in the summer of 2015 and the run rate by the end of 2015 is 75,000/year. That didn't happen. Lets say the shortfall is 5,000 vehicles. Panasonic had to build out that capacity ahead of Tesla's ability to ship those cars that didn't happen. 5,000 vehicles, mostly Model X 90 kWh models is a lot of batteries. About 450 MWh. I think Tesla could have sold 450 MWh of PowerPack last year. That should be about $112 million dollars of revenue. However, they sidestepped this question in the earnings call. I can't find reasonably specific information in the 10-K.
Now, we know that they transitioned Tesla Energy production to the Gigafactory in Q4. That probably delayed things. Does Tesla have about $65 million dollars worth of cells sitting at the Gigafactory waiting for them to put them into PowerPacks? Note that this isn't PowerWall that uses NMC cells, maybe from LG.
