The Mengxi Lanhai Solar Power Plant, the largest single-capacity solar power base project in coal mine subsidence area, has been connected to the grid and started generating electricity in Ordos, Inner Mongolia Autonomous Region, China. The annual power generation of the plant will reach 5.7 billion kilowatt-hours (kWh), meeting the annual electricity consumption of 2 million households. It will reduce standard coal consumption by 1.71 million tons and carbon dioxide emissions by about 4.7 million tons per year. This is equivalent to planting an area of ​​62,700 hectares, and has significant social, environmental and economic benefits.

The plant will be equipped with approximately 5.9 million solar panels in total, with a total power generation capacity of 3 million kilowatts (kW). It is considered one of the key projects in China’s “West-East Transmission” project.

The project is located in a coal mining waiting area. As coal mining can cause land subsidence here, this project has adopted a unique “spring-type” solar panel mounting system for the first time. This ensures that the panels can receive the best light even if land subsidence occurs. The solar power plant also divides multiple solar power generation units, so that even if land subsidence occurs in some areas, the panels can be adjusted to avoid affecting many solar power generation modules.

The project also plans a development model of “power generation above the panels, sheep breeding below the panels, rural development, and industrial tourism.” It aims to realize a composite ecological development model in which high-quality pasture and sand-fixing plants will be cultivated under the solar panels, and sheep and chickens will be raised in some areas, generating solar power and raising them at the same time.
