Tesla is deepening its presence in China with a RMB 4 billion (USD 556 million) investment in its first grid-connected energy storage project on the mainland.
The initiative positions Tesla at the center of China’s expanding grid infrastructure and opens new pathways for grid services in the world’s largest power market.
Located in the Lin-gang Special Area of the Shanghai Pilot Free Trade Zone, the project will feature Tesla’s utility-scale Megapack batteries and serve as a grid-side energy storage station—marking a strategic pivot from behind-the-meter solutions to direct grid participation. Tesla signed the deal in collaboration with the administrative committee of the Lin-gang Special Area, the government of Shanghai’s Fengxian District, and China Kangfu International Leasing.
The installation will not only store surplus renewable power but will also participate in China’s electricity spot market—a relatively nascent but rapidly evolving component of the country’s power sector reform. By engaging in peak-shaving and frequency regulation services, Tesla’s Shanghai station will play a critical role in grid balancing, particularly as China continues integrating volatile renewable energy sources.
According to Tesla China’s energy business general manager Dong Kun, the project will help smooth out electricity supply-demand mismatches, enabling more efficient dispatch of power and improved stability across local grids. These capabilities align closely with China’s ongoing push to modernize grid operations and expand its use of market-based electricity pricing.
Tesla’s expansion into grid-side storage comes at a time when China is actively seeking to build out its energy storage ecosystem. The National Development and Reform Commission (NDRC) and the National Energy Administration (NEA) have previously called for the deployment of 30 GW of new energy storage capacity by 2025, with a growing share expected to be battery-based.
Tesla’s investment in Shanghai—already home to its EV Gigafactory and the recently opened Megapack-dedicated Megafactory—underscores its commitment to capturing value from this growth trajectory. The Megafactory began production in February 2025 and is expected to ramp up significantly, contributing to Tesla’s global target of 50% year-on-year growth in energy storage deployments for the next fiscal cycle.
With a local production base and access to advanced logistics and regulatory frameworks offered by the Lin-gang Free Trade Zone, Tesla appears well-positioned to scale operations efficiently, while minimizing exposure to trade and import tariffs. This geographic synergy could also bolster Tesla’s export ambitions for grid-scale battery systems.
In addition to domestic grid participation, the agreement highlights Tesla’s plans to broaden its partnership with China Kangfu to expand zero-carbon energy solutions globally. While details remain limited, the move signals potential for international joint ventures and financial instruments tailored to energy storage deployments outside China.
Given the relative maturity of Tesla’s battery management software and the increasing demand for grid flexibility worldwide, this cooperation may extend Tesla’s influence beyond manufacturing to include energy system integration and grid services.
Tesla’s move into China’s grid services market reflects a broader industry trend: major technology firms are increasingly playing a role in grid stabilization and energy market reform. With battery costs continuing to decline and policy support intensifying, battery energy storage systems (BESS) are becoming integral to grid decarbonization strategies—not only in China, but globally.
However, long-term success will depend on integration with real-time energy markets, regulatory evolution, and the ability of storage operators to provide consistent value under changing market dynamics. Tesla’s participation in spot trading will be closely watched by competitors and policymakers alike as a barometer for commercial viability in grid-side battery deployment.
