[Green China, Green SOEs] Two Decades of Development at China Datang’s Saihanba Wind Farm

Updated: August 27, 2025

On August 12, 2005, the first wind turbine of China Datang Corporation Limited (China Datang) began operation in Saihanba, Inner Mongolia  Autonomous Region, marking the company’s breakthrough in wind power and the start of a remarkable journey of green development.

Over the past two decades, Saihanba Wind Farm has grown into a large-scale clean energy base integrating wind, solar, and storage, with a total installed capacity of 2.36 million kilowatts, and 800,000 kW under construction. It has generated 47 billion kWh of electricity, saving 15.4 million tons of standard coal and reducing 46.86 million tons of carbon dioxide emissions.

Saihanba, once a barren land, is now a model of ecological restoration. Through innovative approaches, 7,400 mu of sandy land have been rehabilitated, with grassland, shelterbelts, and ecological vegetation thriving beneath photovoltaic arrays.

Today, the smart control center of the wind farm integrates over 90 patented technologies and more than 10 industry standards. With AI-based operation and maintenance systems, the farm has become China Datang’s first onshore wind farm rated under the smart wind farm evaluation system.

As smart energy and eco-friendly models continue to advance, Saihanba stands as a vivid example of the vision that “lucid waters and lush mountains are invaluable assets,” and promises to create more green miracles in the years ahead.
