Tesla Expands Megapack Deployment with China Project

Tesla has announced plans to build its first grid-scale battery storage plant in China, leveraging its advanced Megapack battery system. The project, worth 4bn yuan ($560mn), is a partnership with China Kangfu International Leasing and Shanghai's local government. Once operational, the facility will become China’s largest grid-scale battery storage station.

Tesla began producing Megapacks at its Shanghai gigafactory earlier this year. With an annual capacity of 10,000 units — equal to 40GWh — the plant can support large-scale energy storage demand. Each Megapack stores 3.9MWh, enough to power 3,600 homes for one hour.

Growing Role of China in Tesla’s Energy Strategy

Tesla shipped more than 100 Megapacks from Shanghai in the first quarter, primarily to Europe and Oceania. The Shanghai factory complements its 40 GWh/yr facility in California, reinforcing Tesla’s dual-continent approach to scaling energy storage.

Global demand for energy storage continues to rise, driven by renewable integration and declining costs. According to Chinese research institute EV Tank, shipments of storage batteries are projected to climb to 1,550GWh by 2030. This positions Tesla to capitalize on exponential growth in both the Chinese and international markets.

The Metalnomist Commentary

Tesla’s move to build a grid-scale battery storage plant in China highlights its strategy to dominate global energy storage. By localizing production and deployment, Tesla strengthens its foothold in the world’s largest energy transition market. However, its reliance on China also exposes it to potential policy and geopolitical risks.
