100 MW Fishery-Solar Hybrid Plant Connected in Taizhou, Jiangsu
A 100 MW fishery-complementary photovoltaic plant in Hailing District, Taizhou, Jiangsu Province has achieved full grid connection. Solar arrays are installed above aquaculture ponds, allowing power generation and fish farming to share the same water surface and significantly improving land-use efficiency. The plant is expected to generate over 100 million kWh of clean electricity annually, enough to meet the needs of tens of thousands of households, while reducing carbon emissions by roughly 100,000 tonnes per year. The project model is being replicated across Jiangsu's coastal aquaculture belt.
Gansu Section of the Gansu-Zhejiang UHVDC Project Completed
The Gansu section of the Gansu-Zhejiang ±800 kV ultra-high-voltage direct current transmission project has been completed, clearing the way for subsequent energization and commissioning. The line spans more than 2,000 kilometers and is designed to carry around 8 GW, with the majority coming from wind and solar generation in Gansu's desert renewable energy bases. Once operational, the project will deliver large volumes of clean power to the Yangtze River Delta load center, ease west-to-east transmission congestion, and support China's national strategy of large-scale renewable base development.
Morocco Commissions 25 MW / 125 MWh Battery Storage System
A 25 MW / 125 MWh battery energy storage system has been connected to the grid in Morocco, representing one of the country's first utility-scale storage facilities. The five-hour duration system will provide frequency regulation, peak shifting and backup capacity as Morocco accelerates its renewable energy program, which targets more than half of installed capacity from renewables.
