Tesla will also make gearboxes, electric motors for the Model 3 at its Gigafactory

At Tuesday evening’s State of the State address, Nevada Governor Brian Sandoval said, “Tonight, I am pleased to announce that Tesla will expand its investment in Nevada by producing the electric motors and gearboxes for the Model 3 at the Gigafactory.” This work is expected to create some 550 new jobs at the factory, as well as spur an extra $350 million in investment. In his speech, the governor thanked Elon Musk’s car company for “doubling down” on its commitment to Nevada, noting that the company’s presence had already led to economic growth in the state.

As it stands, the futuristic car company employs 1,000 full-time workers at the Nevada plant, and another 2,000 construction workers are helping build the behemoth of a factory. By the time it’s entirely finished, the Gigafactory will live up to its name, measuring the same size as 107 NFL football  fields, with more than 10 million square feet of operational space. It’s expected to be the world’s largest building when completed, and by 2018, Tesla anticipates that the Nevada factory will churn out 35 gigawatt-hours a year of lithium-ion battery cells. That’s equivalent to the production of the rest of the world combined.
