Tesla is a battery company that just so happens to also make a couple of cars. When you look at it that way, it makes a lot more sense.

You are making me rethink my position a little bit. Thanks!

If you look a the energy industry now, there's an iron triangle, if you will, between fossil fuel extraction, electric utilities, and the automobile industry. Tesla is aiming to replace all three sides with solar, batteries, and electric cars. A person could use Tesla products and, in theory, not interact with the current energy sector of the market at all. Which, if it works, would be some kind of disruption!

What advantage do they have in battery tech that say, Panasonic (who provides their batteries), doesn't?

For further comparison, the total capacity of existing pumped hydroelectric storage plants is 740 000 GWh. (This puts plans of battery-based electricity storage in a rather harsh perspective.)

I believe this number only includes dams with reverse pumping. The global production capacity for all hydroelectric power is much larger, but it's not a widely used number, since you typically don't empty a reservoir due to the lower water having less potential energy.

So this capacity number is a bit theoretical, since you wouldn't use it that way in practice. But then again, so is the capacity number for batteries, since you really want to avoid doing a full discharge.

Annual global hydroelectric production is a more useful number, and is a little more than 4 000 TWh.

Tesla is.

That is common misconception. Tesla repackages batteries bought from Panasonic.

I suspect SolarCity's microgrid program and system service contract (which allows for customers to participate in yet-to-be-developed markets) is intended to disrupt the whole shit. IIRC, SolarCity already purchased a utility company. I expect they're looking to buy more utility poles & make their own market, cash squeeze realities notwithstanding.

"Vertical integration can make a lot of sense in weird markets where goods aren't fungible or there isn't a high quality market for trading. Electrical power is basically the opposite of this though. There is a very very large and very liquid market for pricing electrical power. I see no reason that SolarCity can't just be a supplier to this market while Tesla Owners would be consumers." Yes, but the point is that there is a reason to combine those two, if the long-term agenda is to create a next-generation energy company, as opposed to simply competing in their respective markets, which was a response to pfarnsworth's comments.

I do agree with the likelihood of certain shareholders being negatively affected. You are also probably right about the motivation being cashflow, but that is due to circumstances/timing rather than a lack of synergy.

They are creeping in that direction though. Delta purchased their own refinery in 2012:

Given that, "there is a deep, liquid market for jet fuel," is having Emirates airline and Emirates National Oil Company under the same umbrella poor strategy?

You're also omitting the fact/point that the energy industry is evolving very quickly and that calls in to question the established markets. Energy over-supply in general creates opportunities for disruption and new business models.

Yes. The only reason it exists this way is because they're both owned by the corrupt government/monarchy of Dubai.

Keep in mind that under the same umbrella you also have everything from banks to a cement company to hotels to a mineral water company. This isn't a coherent business strategy, it's just what happens when a single family rules over an entire economy and basically owns everything.

You could equally argue that is exists that way because they need to deploy extremely large amounts of capital. So, an infrastructure company in a region that is going through phenomenal, albeit temporary growth, makes a lot of sense. Once that growth levels off they could transition to higher-tech endeavors.

also, a sweet deal like: "charge your electric car for a discounted rate m when your home already has SolarCity brand electricity" is a much easier sale than "Oh, you've got a Tesla... don't you want to charge it with your standard meter rate from Vivent?"
