@elon.kekius: I ELON just clarified the plan for building the TERAFAB. The Advanced Technology Fab built at Giga Texas will not be “the TERAFAB.” It will be a smaller fab where they will iterate on chip designs. The TERAFAB wouldn’t even fit on the Giga Texas campus. Several sites for the TERAFAB are under consideration, and it will need thousands of acres and over 10 GW of power at full scale. My opinion: To put this in perspective, Tesla would need 2,000-5,000 acres for the entire TERAFAB lot. This would equal ~87-200 million square feet of available land space for power and battery backup with Megapacks, with ~20-60 million square feet of available space for the actual building. Just for reference, backing up a facility like this with a ~5-15 minute battery backup would require 168 Megapacks and it would for sure need its own power production such as natural gas turbines or maybe even its own dedicated power plant.
