On April 30, the Dachaidan 1 GW Wind-solar-storage Project, developed by CHN Energy Qinghai Branch, achieved full-capacity grid-connected operation.
As part of China’s second batch of large-scale clean energy base projects, the facility is located in the Dachaidan Administrative Committee of Haixi Prefecture, Qinghai Province, integrating 700 MW of photovoltaic power and 300 MW of wind power.
The project pioneers a hybrid system of plateau-adapted wind turbines, high-efficiency photovoltaic panels and diversified energy storage, incorporating eight distinct energy storage technologies to stabilize fluctuations in renewable energy output. Innovative construction methods, such as micro-poured piles and prefabricated cabins, enabled the creation of an eco-friendly "zero ecological disturbance" demonstration project. Upon full operation, it is projected to generate 2.1 billion kWh of electricity annually, equivalent to saving 700,000 tons of standard coal and reducing carbon dioxide emissions by 1.93 million tons.
The project’s completion marks a breakthrough in China’s development of ultra-high-altitude multi-energy complementary systems. It strengthens Qinghai’s position as a national hub for clean energy and bolsters the implementation of the country’s West-to-East Power Transmission strategy.
