Tesla will open a new Megafactory in Shanghai, China, that is capable of producing 10,000 Megapacks a year, the company announced in a tweet Sunday.
A Megapack is a very large battery that stores energy, helps stabilize the power grid and prevents outages.
Tesla currently has a Megafactory in Lathrop, California, that is capable of producing 10,000 Megapacks units each year, according to the company's website.
In a tweet Sunday, Tesla CEO Elon Musk said the factory in China will supplement output from the factory in California.
Tesla and Musk did not immediately respond to requests for comment.
