Jiangsu has become the first province in the Yangtze River Delta to surpass 100 gigawatts (GW) of installed new energy capacity, according to State Grid Jiangsu Electric Power Co., Ltd. The milestone was achieved with the recent grid connection of several projects, including the 81.6 MW Huaren Nanmo fishery–solar hybrid plant in Hai’an, Nantong. The facility is expected to generate 93.88 million kilowatt-hours (kWh) of electricity annually, with 95% of its core components—such as PV modules and transformers—sourced from local manufacturers in Jiangsu.
The Yangtze River Delta—comprising Shanghai, Jiangsu, Zhejiang, and Anhui—covers just 1/26 of China’s landmass but contributes nearly one-quarter of the country’s GDP. As of May 2025, the region’s total installed new energy capacity exceeded 232 GW, positioning it at the forefront of China’s green energy transition. Jiangsu alone accounts for 43.4% of that total, offering a scalable model for low-carbon energy development and high-quality economic growth.
As of May 2025，Jiangsu's new energy power generation capacity accounts for 46.66% of the province’s total installed power capacity. This data demonstrates that new energy plays a vital role in Jiangsu’s power structure, reflecting the province’s significant achievements in renewable energy development.
The specific components of Jiangsu’s new energy capacity include:
Photovoltaic Power Generation: Installed capacity reaches 82.2569 gigawatts (GW), with distributed photovoltaic capacity at 58 gigawatts (GW).
Wind Power: Total capacity is 23.3715 gigawatts (GW), with offshore wind power contributing 11.8325 gigawatts (GW), ranking second nationwide.
The province's booming clean energy sector has also strengthened its industrial supply chain. In the photovoltaic industry, the Yangtze River Delta has generated more than RMB 1 trillion in annual revenue. Jiangsu, in particular, is home to over 40% of the country’s PV module production capacity and has led the nation in silicon wafer and solar cell output for ten consecutive years.
From January to April this year, Jiangsu’s new energy generation exceeded 5.08 billion kWh. The share of renewables in the province’s electricity consumption has jumped from less than 5% in 2003 to more than 30% today, driven by continued progress on both the supply and demand sides.
“To further integrate renewable resources, we’re accelerating several DC transmission projects,” said Gao Zhengping, Deputy Director of the Planning Department at State Grid Jiangsu. “The second and third phases of the Yangzhou–Zhenjiang DC line will soon come online, and we’re building a new DC corridor between Nantong and Suzhou via the existing Suzhou–Tongzhou GIL tunnel. This approach avoids additional land use while addressing cross-Yangtze transmission bottlenecks, helping to advance the green transformation of the region—and offering valuable experience for global energy transition efforts.”
