Greetings to all!
I am in favor of
Nevada as the location for
Tesla Battery Gigafactory.
Reasons:
1) Proximity to raw materials -- You don't want to pay for transportation twice, i.e. to get the raw materials and then to ship the final product.
2) Shipment costs to the assembly plant -- Similar to the explanation in
1) but from the distance point of view. Reno, NV is just 9 hours away from Fremont, CA by train. So regular shipment is available. In contrast, it takes 2-days to travel from Phoenix, AZ to Fremont, CA by train according to Google Maps. (Similarly, by car it's under 4 hours from Reno, NV and 10+ hours from Phoenix, AZ.)
3) Business climate -- Many businesses including tech companies have moved their finance units to NV for
tax reasons. TSLA does not need to spend money for lobbying or to work hard on political connections to get such tax treatment. That means less distraction for the management.
4) Investor / Fan buzz -- Las Vegas, NV has annual tech fairs and is able to attract thousands of people regularly. San Francisco, CA hosts dozens of tech events per year. Getting such fan base to travel to Reno, NV would be relatively easier than to AZ or NM in my opinion. In long-term, such steady attention flow would benefit the company to maintain high publicity. As they say it in Iowa,
"If you build it, they will come."
5) Housing / Talent pool -- Some of the engineers from the Fremont plant might be transferred to the Gigafactory location. Relocation costs money upfront. Some people might prefer to maintain their affinity to California. For example, Elon Musk himself might want to maintain his residence in California because of his children going to school there. So Nevada is closer, cheaper, and is in the same time zone.
Why not Arizona or New Mexico?
* The sun might shine brighter in AZ and NM. However, with energy storage capacity, solar power might not be the only reason for location choice. In fact NV being on higher altitude, it might actually provide more UV radiation, which is what you need for photovoltaic cells should they go for solar panels from SolarCity.
* Higher altitude would also mean cooler temperature, which makes energy storage/output more efficient in the long run. In fact, average summer temperatures topping 100F in AZ and NM would work against you since lithium-ion batteries perform better under 85F. In a closed facility with large roof surface area, cooling down expenses might add up meaningfully. As a result annual average variable costs in AZ and NM would be higher than in Nevada.
* The only reason why I think AZ and NM became candidates was because of their renewable energy production. They mostly have power tower designs (aka heliostats) that use concentrated sunlight from multiple mirrors and then convert energy through steam generators (with temperatures at 1,000F). However, there is a new concern that the power tower design causes high mortality of birds (see
Birds Fly or Fry at Solar Energy Plant | Ivanpah Solar | LiveScience). This might backfire from animal protection activists and possibly even the government. I don't think TSLA wants to face criticism about killing birds while they preach about protecting the planet...
On the other hand, SolarCity's uses photovoltaic solar panels. So they don't necessarily depend on high solar radiation but rather high UV radiation, which is greater on higher altitude like in NV (i.e. where the air density is thinner). Therefore, AZ and NM are not necessarily top candidates.
* Marginal cost of transportation from AZ / NM might be higher than from NV due to longer railroad distance. That defeats the purpose of efficiency gains from in-house battery production.
Also, I honestly would not want my high-value components to stay in transit for too long. Even if shipment takes two days, that means there is a risk of overnight accident or something else, God forbid. It's much more comfortable when you know that the cargo has been shipped in the morning and you have it at the assembly plant same evening, which is the case for Reno, NV -> Fremont, CA.
Why not Texas?
* The only reason I could think of building a Gigafactory in TX is if there were another assembly plant nearby, e.g. in Houston, TX. However, even that would imply export driven production. The facilities in Fremont, CA are sufficient for producing 500K vehicles per year. Until that production level is saturated, I don't see any need to stretch yourself thin across the country and across time zones.
Plus, there is this risk of factory shut downs during tornadoes and hurricanes. As the climate continues changing, there will be greater volatility of weather patterns. Such fluctuations create unnecessary logistical complexities and uneven shipment patterns, which would adversely affect production patterns at the assembly plant in Fremont, CA. With high degree of automation through robotics, you don't need to store large inventory of batteries on side. Instead you want to use that space for additional assembly machinery. In other words, you want the production process to be in sync across the whole manufacturing chain. Also, a smoother production pattern would make it much easier for financial planning, cash flow management, and hedging, all of which affect profit margins.
* The assembly plant in Netherlands makes it a compelling case to build the Gigafactory near Houston, TX so that you could ship those battery packs to Europe. Then why not build a Gigafactory in Europe?..
