Tesla will send engineers and production staff from its Shanghai plant to help expand its factory in Fremont, California, Bloomberg said today, citing people familiar with the plans.

Tesla will send on-site staff, particularly automation and controls engineers, to help expand production at the Fremont plant, where Tesla's Model S, Model X, Model 3 and Model Y cars are made, the people said.

About 200 people will travel to Fremont and the assignment will last at least three months, one of the people said, adding that the first workers will depart as soon as this month.

Tesla produces the Model 3 as well as the Model Y at its Shanghai plant, and the second-quarter earnings report the company announced on July 20 showed that Giga Shanghai has an annual capacity of more than 750,000 vehicles, its largest plant in the world.

Tesla's California plant has an annual capacity of 650,000 units, including 100,000 Model S and Model X units, and 550,000 Model 3 and Model Y units.

In addition to these two factories, Tesla's factories in Berlin, Germany and Texas, US have an annual capacity of more than 250,000 units, and they currently only produce the Model Y.

Several local media previously reported that Tesla upgraded the production line at Giga Shanghai in late July and early August, and that the upgrade was completed, expanding Giga Shanghai's annual capacity to about 1.1-1.2 million units.

The upgrade at the China plant took about five weeks and included machine maintenance and improvements overseen by automation and controls engineers, according to the Bloomberg report today.

The upgrade helped double the plant's annual production capacity to about 1 million vehicles, the report noted.

Tesla's China-made vehicles sold 83,135 wholesale units in September, including 5,522 for export and 77,613 for delivery to local consumers, data released last month by the China Passenger Car Association showed.

On October 24, Tesla lowered the prices of its entire Model 3 and Model Y lineup in China.
