Speaking of Mexico, I've seen several sources mention that Mexico's power grid instability/strength is a huge problem for building a new factory there. Some of these sources are very Tesla focused which is confusing as they should know that a good part of Tesla's business is in STABALIZING THE GRID WITH GIANT BATTERIES AND CHARGING THOSE BATTERIES WITH SOLAR.

Tesla has faced issues such as these in Germany, China, and the US, in California, Nevada and Texas, not so much in New York. So it's probably useful to review the major water uses is automobile plants and then typical Tesla solutions:
First generically:
Water conservation is becoming an increasingly important issue in sustainable vehicle manufacturing, writes David Isaiah

Second Tesla:
In rough order of auto plant water use intensity:
1.
Surface preparation and coating; Tesla has approached this with multiple solutions. Choosing materials and processes that reduce need for preparation and coatings has been an iterative effort that has combined with cost reductions in every location.
2.
Painting: This has been iterative also with the Geico Taikisha solutions reducing water usage, coatings and process control (well documented in TMC threads). Further those painting processes themselves reduce use of water, preparation and coatings, so combine to reduce cost for materials, water and labor.
3)
Washing, rinsing etc: This includes a multitude of small things that are vastly reduced with increased operational cleanliness and better quality control including robots and improved cleaning techniques. To visually see all this, just visit Tesla Berlin, Austin or Shanghai then visit any other auto plant. The contrast will be informative.
4)
Cooling: This includes all the industrial processes that require cooling. Tesla factory design is structured to reduce costs and it becomes evident when seeing the plant operations that Tesla uses less industrial cooling than do many others. The same factory visits make this one clear.
5)
Air Conditioning and boilers: New designs are very much better designed to reduce energy use and water use. Tesla innovates here every time.
6) Energy use rather than water requires no comment in this forum. It is an obvious proven business and mission of Tesla. That, joined with the water management and reuse processes that are part of every Tesla plant shows how they always focus on every part of cost reduction, water and energy being two of the largest controllable costs.
Based on past discussions regarding Fremont expansions, Nevada, Austin, Brandenburg and Shanghai Tesla manages to always use less water and energy than has been included in first plans.
Monterrey is thus another case of Tesla preparing to solve problems that might otherwise be prohibitive. I've worked in Monterrey, so I know the local impediments regarding energy, water and infrastructure will be ones Tesla will need to solve, rather than expecting governmental support to solve these issues. They will also need continuing education and other support for the workforce; those are things Tesla is prepared for.
This one will be epic! It will be transformative in ways we really won't understand until, say, 2025 or so, even though they'll be in operation next year.
