Tesla’s energy storage Megafactory in Shanghai has commenced trial production of its Megapacks large-scale energy storage batteries, with full mass production expected by the first quarter of 2025.

The Shanghai Megafactory is Tesla’s first production site for Megapacks – its second facility in Shanghai – outside the United States, with an initial production capacity of 10,000 Megapacks per year.

Its construction began in May 2024 and trial production was achieved within seven months, exceeding previous project timelines.

This equates to approximately 40 gigawatt-hours of energy storage and represents a total investment of 1.45 billion yuan (around US$198.6 million), according to local authorities.

Tesla has not disclosed specific details regarding the commercialization of Megapacks produced at this new facility.
