Recently, the Ningxia Lingwu 4 million kW Coal Mining Subsidence Area New Energy Base, the largest single photovoltaic project in China's coal mining subsidence area, in which China Power Construction Corporation (China Power) participated, was completed and put into operation. This will provide strong impetus for the efficient transformation of resource advantages in Northwest my country's energy base and high-quality economic and social development.

The Ningxia Lingwu 4 million kW Coal Mining Subsidence Area New Energy Base is an important component of my country's second batch of large-scale wind and photovoltaic bases in the "desert and Gobi" areas. It covers approximately 120,000 mu (about 8,667 hectares) and transmits over 7 billion kilowatt-hours of clean energy annually. China Power's subsidiaries, including Shandong Electric Power Construction Corporation III, Hubei Engineering Company, Northwest Institute, Guiyang Institute, Shanghai Electric Power Construction Corporation, Shandong Electric Power Construction Corporation, and Power Construction Nuclear Power Company, participated in its construction.

The completion and operation of the Ningxia Lingwu 4 million kW Coal Mining Subsidence Area New Energy Base marks the full completion of the Ningxia coal mining subsidence area project, which covers an area of ​​180,000 mu (about 12,667 hectares) and has a total installed capacity of 6 million kilowatts. The Ningxia Coal Mining Subsidence Area Project comprises the Ningdong 2 million kW Coal Mining Subsidence Area Composite Photovoltaic Base and the Ningxia Lingwu 4 million kW Coal Mining Subsidence Area Composite Photovoltaic Base, covering a total area equivalent to approximately 16,000 football fields. It includes six 330 kV step-up substations and 200 kilometers of transmission lines.

The project will transmit approximately 10.8 billion kilowatt-hours of clean electricity annually through the Ningxia-Zhejiang ±800 kV Lingshao UHVDC transmission line, contributing to the nation's efforts to optimize energy allocation and build a stable clean energy supply system. Simultaneously, combined with photovoltaic desertification control, it will reduce wind speed and evaporation, thus restoring desertified land.

Upon full completion and operation, the project will meet the annual electricity needs of 7.2 million households, saving approximately 3.24 million tons of standard coal. Its economic, social, energy-saving, and environmental benefits are significant, making a crucial contribution to my country's goal of achieving a low carbon footprint and promoting ecological protection and high-quality development in the Yellow River Basin.
