The largest single-unit photovoltaic power station in coal mining subsidence area in China has officially entered commercial operation.

The Mengxi Blue Sea Photovoltaic Power Station covers an area of ​​about 70 square kilometers, with an installed capacity of 3,000MW and more than 5.9 million solar panels deployed throughout the site.

The project is located in Otog Front Banner, Ordos City, Inner Mongolia Autonomous Region. It mainly utilizes coal mining subsidence areas and areas to be mined. It is the second batch of large-scale wind and solar complementary projects in desert Gobi areas in my country, and is also an important supporting project for the national "West-to-East Power Transmission" Ordos Shanghai Temple in Inner Mongolia to Linyi, Shandong ±800kV UHV DC transmission project.

The State Energy Company responsible for the construction of the project introduced that the project uses H-shaped steel piles as the basis of the single-axis tracking system, reducing the pile diameter from 400 mm concrete precast piles to 100 mm, greatly reducing the damage to the grassland landscape.

In the same area, the project is divided into multiple photovoltaic units. When part of the ground sinks, the PV modules can be adjusted more flexibly to ensure the best lighting angle.

The National Energy Corporation said that the project innovatively adopted the integrated construction technology of component tracking, which is the first application in the world. This method greatly reduces labor and improves installation efficiency by 25%. The project also uses a new type of intelligent cleaning robot, which can efficiently remove dust and dirt on photovoltaic modules to maintain the conversion efficiency of the modules.

It is worth noting the power transmission capacity of the project. With the concept of "fire and light bundling, joint transmission, comprehensive demonstration, and technology leadership", the project will transmit green electricity from western Inner Mongolia to Shandong across thousands of miles. The annual power generation is expected to be 5.7 billion kWh, which is enough to meet the annual electricity needs of 2 million households, which is equivalent to solving the electricity needs of a medium-sized Chinese city.
