Last week, news leaked out that Rivian was planning to build a second US manufacturing plant for its electric vehicles and batteries, and now more details have leaked out. The company plans to invest $5 billion initially in the second plant, dubbed Project Tera, with construction slated to start in the fall of 2021, according to Reuters. The aim is to begin production by the second quarter of 2023.

The second plant will reportedly include a 50 gigawatt-hour (GWh) battery cell production operation and a product and technology center. There's no word on where it'll be built, but the company is reportedly looking at land east of Mesa, Arizona, near Gold Canyon, according to Reuters' sources. Rivian Chief Executive R.J. Scaringe has reportedly spoken with Arizona Governor Doug Ducey about the project.

Rivian previously acknowledged that it's looking to expand. “The company has recognized that future production and product plans will not be fully met by the current capacity at Rivian’s Normal, Illinois facility,” it said in the document seen by Reuters.

The plant would supposedly support around 10,000 jobs, though many of those could come indirectly. For a startup that has so far not produced a single vehicle, however, the investment and job figures would be impressive. Rivian is backed by Ford, Amazon and other companies and could reportedly soar to a $50 billion value in a possible public listing later this year, according to Reuters' previous story.
