Tesla recently released its Q2 performance report, showing an energy storage deployment capacity of 9.6 GWh during the quarter—a decrease of 0.8 GWh quarter-on-quarter.

This marks the second consecutive quarter of decline for its energy storage business. Data indicates that in Q1 2025, Tesla's energy storage deployment reached 10.4 GWh. In Q4 2024, the company had achieved a peak of 11 GWh.

Despite the recent sequential declines, Tesla’s total energy storage deployment for the first half of the year reached 20 GWh. 

Meanwhile, the company has made progress in China’s energy storage market. On June 20, Tesla signed a contract in Shanghai for its first grid-scale energy storage project in mainland China at the GWh level. The project primarily utilizes Megapack systems manufactured at Tesla’s Shanghai Megafactory, with a total investment of RMB 4 billion. The first phase, with a capacity of 300 MWh, is scheduled to be completed and operational within this year.
