Tesla shipped more than 2,000 Megapack energy storage units from its Shanghai megafactory in 2025, according to company data, as utilities race to meet 2030 renewable targets. Europe and Australia received the majority of systems as grid operators accelerated coal phaseout projects and grid stabilization work.
The Lingang facility reached full production capacity within eleven months of its February 2025 launch, industry reports show. Tesla Energy now operates two Megapack plants: the California facility opened in 2022 and the Shanghai megafactory, the company's first dedicated storage plant outside the United States.
Each unit stores 3.9 megawatt hours, according to Tesla specifications. Orders exceeded forecasts as Europe advanced coal retirement deadlines and Australia expanded transmission balancing capacity.
The Shanghai output reflects surging global demand for utility-scale battery storage. Worldwide installations surpassed 300 gigawatt hours in 2025, while U.S. interconnection queues alone contain approximately 890 gigawatts of storage capacity awaiting grid connection. Solar and wind projects add capacity faster than storage manufacturers can deliver, extending backlogs into 2027.
