Tesla's Shanghai energy storage Megafactory marked a major milestone on July 29 as its 1,000th Megapack energy storage system rolled off the production line, bound for Europe.

This achievement comes less than six months after production began in February.

Located in the Lin-gang Special Area, the Shanghai facility is Tesla's first energy storage manufacturing site outside the United States.

Each Megapack delivers approximately 3.9 megawatt-hours of electricity storage, offering a utility-scale energy storage solution designed to stabilize power grids and support the integration of renewable energy sources.

The Shanghai factory is expected to produce 10,000 Megapacks annually, equivalent to nearly 40 gigawatt-hours of storage capacity.

The first Megapack units from the Shanghai plant shipped were exported in March.
