Tesla CEO Elon Musk has confirmed Germany as a preferred destination for a new Tesla Gigafactory.

At the annual shareholder meeting earlier this month, Musk also indicated plans to build a Gigafactory in Shanghai, China, registering a new company in the region’s Free-Trade Zone, an area designated by the Chinese government to be more relaxed with free-market and manufacturing policy for foreign countries.

“Germany is a leading choice for Europe. Perhaps on the German-French border makes sense, near the Benelux countries,” said Musk in a Twitter post.

At the moment, Tesla has already established a base in Pruem, Germany, for its Grohmann Engineering division, which builds production lines for its batteries. Its European headquarters is based in Amsterdam with a separate factory in Tilburg, which is used for final assembly for the Model S and the Model X. Ultimately, Tesla’s goal is to build up to 12 Gigafactories, spread throughout the globe. including continued expansion of Nevada’s own Tesla Gigafactory, currently a third of its intended size after starting construction in 2014.
