Solar energy and storage system with a capacity of 6 MW and 8 MWh to supply power to Tesla's Shanghai Gigafactory through a solar and Megapack project.
The Shanghai Megafactory, a subsidiary of the Shanghai Lingang Economic Development Group, has recently completed its operations ahead of schedule, marking a significant milestone in the region's renewable energy sector. The factory, which started construction in May 2024, boasts an energy storage capacity that matches that of Tesla's Megafactory in Lathrop, California.
Tesla's solar-plus-storage project at the Shanghai Megafactory represents the first large-scale industrial microgrid in the region. As part of this project, Tesla has installed a 6-megawatt (MW) rooftop solar array and an 8-megawatt-hour (MWh) Tesla Megapack energy storage system. The solar-plus-storage project is a significant milestone in Shanghai's push toward distributed renewable energy.
The solar energy generated by the rooftop array will be stored in the Megapacks for later use during peak demand or outages, allowing the factory to consume 100% of its solar-generated electricity on-site. The Shanghai Megafactory's annual energy storage capacity is around 40 gigawatt-hours (GWh), making it a substantial player in the region's renewable energy landscape.
Tesla's solar-plus-storage project at the Shanghai Megafactory is part of a broader push by the company to integrate solar power and energy storage across its global operations. This project also marks Tesla's first large-scale grid-side energy storage installation in mainland China, complementing their automotive manufacturing presence in Shanghai and positioning Tesla strongly within China’s rapidly growing clean energy market.
The Shanghai Megafactory is Tesla's first energy storage manufacturing site outside the U.S. and serves as the primary global production hub for the Megapack, Tesla's utility-scale battery system. The factory has an annual capacity of 10,000 Megapacks.
The first phase of the Tesla's Megapack energy storage station in Shanghai is expected to provide about 300 megawatt-hours (MWh) of energy storage capacity upon completion within 2025. The project aims to stabilize Shanghai’s power grid by storing excess energy during low demand and discharging it during peak demand times in summer and winter, thus reducing grid stress and costs associated with power supply during peak seasons.
Once operational, the station will participate in electricity spot trading, helping to balance peak and off-peak power demand and enhance overall grid stability. This project aligns with the country’s push for renewable energy integration and advanced energy storage solutions to support a more reliable, cost-effective, and greener electricity grid.
Tesla has already demonstrated a similar setup at Giga Texas, where a massive rooftop solar array spells out the word 'TESLA' and is complimented by a Megapack installation with 131MW of power capacity and 262 MWh of power storage capacity. The Shanghai Megapack project is a major step for Tesla’s energy division in China, setting the stage for a greener and more sustainable future in the region.
