Tesla’s first energy storage plant outside the US, it will produce Tesla “Megapacks”, utility scale batteries that can feed the grid during peak demand periods.

Each unit can store 3.9 MWh of energy, enough to power around 3,600 homes for an hour, Tesla says.

The company plans to make 10,000 of them a year, starting in the first quarter of next year.

The announcement follows Tesla’s purchase of a 20ha site, which it made in December for $30m.

The factory will be Tesla’s second in China.

Its nearby gigafactory, which broke ground in 2019, makes Model 3 and Model Y cars. It is now the company’s main production site, able to produce 1.1 million units a year, and Tesla is hoping to expand it in the near future.
