Tesla Gigafactory 1, Nevada

Tesla’s first Gigafactory is primarily a lithium-ion battery plant, being built with Tesla’s partner Panasonic, to make batteries for Tesla cars and its Powerwall domestic battery storage units, as well as motors and other parts for its cars.  If the Gigafactory 1 is completed as planned (maybe in 2020), it will be among the largest buildings in the nation. The Gigafactory is projected to have a footprint of more than five million square feet, inside of which will be two main floors, one at grade and one 41 feet above it. It is being built in more than a dozen discreet “blocks”, one at a time, adjusting to production methods and demands as they go. Construction started in 2014, and it was around half done in 2018, and began making batteries, its primary function, in 2016. Final cost is estimated to be $5 billion.
