Jiangsu Province in eastern China has surpassed 100 GW of installed solar PV capacity, becoming the country’s first provincial-level region to reach the milestone, with distributed solar accounting for nearly 70% of capacity. The province plans further rapid expansion through 2030 and 2035, while upgrading grids, storage and digital systems to manage rising solar penetration and improve renewable-energy utilization.
Jiangsu Province in eastern China has become the country’s first provincial-level region to surpass 100 GW of installed solar PV capacity, highlighting the rapid expansion of distributed generation in one of China’s most densely populated and economically developed areas.
According to data released by State Grid Jiangsu Electric Power and reported by Xinhua News Agency, Jiangsu’s cumulative solar PV capacity reached 100.08 GW by late July 2026. Solar now accounts for more than 38% of the province’s total power generation capacity, making it the largest single source of installed generation capacity in Jiangsu.
The milestone is notable because Jiangsu’s solar growth has been driven primarily by distributed PV rather than large-scale utility projects. Distributed solar installations reached 69.29 GW, accounting for nearly 70% of the province’s total PV capacity, while centralized solar stood at approximately 30.79 GW.
