Shanghai – In a strategic expansion of its global energy portfolio, Tesla Inc. has signed its first-ever deal in China to construct a grid-scale battery power plant, which is set to become the largest of its kind in the country once completed.
The American EV and energy company announced the project through Chinese social media platform Weibo, emphasizing the importance of utility-scale battery systems in stabilizing energy grids, especially in regions relying heavily on intermittent renewable sources like solar and wind.
The agreement, reportedly worth 4 billion yuan (approx. $556 million), was signed between Tesla, the Shanghai municipal government, and China Kangfu International Leasing, according to Chinese financial news outlet Yicai and Reuters.
Massive Megapack Production at the Core
Tesla revealed that its Shanghai-based battery plant had produced over 100 Megapacks in Q1 2025. The Megapack, Tesla’s flagship grid-scale energy storage solution, can supply up to 1 megawatt of power for four hours, making it ideal for utility deployment.
“The grid-side energy storage power station is a ‘smart regulator’ for urban electricity, which can flexibly adjust grid resources,” Tesla said on Weibo (via Google translation). “It will effectively solve urban power pressure and ensure a safe, stable, and efficient electricity supply.”
Once operational, the facility will not only become China’s largest energy storage site but also represent a milestone for Tesla’s presence in the world’s fastest-growing clean energy market.
Why the Deal Matters
This development is significant for multiple reasons:
-
Geopolitical Context: It comes amid rising trade tensions between Washington and Beijing, especially after U.S. President Donald Trump imposed fresh tariffs on Chinese imports. Tesla CEO Elon Musk, a previous Trump ally, faces a complex policy landscape in both countries.
-
Competition with Chinese Giants: Tesla enters the deal as domestic players like CATL (Contemporary Amperex Technology Co. Limited) and BYD dominate the battery market. CATL alone holds an estimated 40% share of global battery production.
-
Market Growth Opportunity: China is aggressively expanding its battery storage capabilities. In 2024, Beijing set a target to add nearly 5 gigawatts of battery-backed power by the end of 2025, aiming to reach 40 GW total capacity.
According to sources, CATL may supply some of the cells and battery packs used in the Megapacks, highlighting a mix of competition and collaboration between the firms.
Global Battery Demand Accelerates
Tesla’s energy storage arm is scaling rapidly. The Shanghai facility not only serves China but also exports Megapacks to Europe and Asia. According to the International Energy Agency, global battery energy storage capacity surged by 42 GW in 2023, nearly doubling the previous year’s increase.
The price for each Megapack in the U.S. market is just under $1 million, although pricing for the Chinese market has not been disclosed.
As China accelerates its transition away from fossil fuels, Tesla’s entry into its large-scale battery infrastructure market may shape a new chapter in the global clean energy race, even as political uncertainty remains a looming factor.
