The 2 million kilowatt photovoltaic sand control project in Kubuqi, Mengxi base, which is the largest single unit in China, was successfully connected to the grid
After more than two years of construction, the 2 million kilowatt photovoltaic sand control project in Kubuqi, Mengxi Base, jointly invested and constructed by Three Gorges Energy and Elion Clean Energy, has recently been connected to the grid at full capacity in Hangjinqi, Ordos City, Inner Mongolia. This is also the largest single ecological photovoltaic sand control project in China, with an average annual production of 4.1 billion kilowatt hours of green electricity, which can save 1.23 million tons of standard coal combustion, reduce carbon dioxide emissions by 3.198 million tons, reduce sulfur dioxide emissions by 29,500 tons, reduce nitrogen oxide emissions by 8,600 tons, and reduce soot emissions by 12,300 tons.
The Kubuqi 2 million kilowatt photovoltaic sand control project in Mengxi Base started construction on October 16, 2021, covering an area of 100,000 mu with a total investment of 11.15 billion yuan. The construction content includes 2 million kilowatt photovoltaic farm area, 400,000 kilowatt/800,000 kilowatt-hour energy storage system, 3 220kV booster stations and 100,000 acres of desert management ecological construction project.
According to Zhao Jinquan, the person in charge of the project in Kubuqi of China Three Gorges Corporation, the 2 million kilowatt photovoltaic sand control project in Kubuqi of Mengxi Base adopts the three-dimensional ecological photovoltaic sand control mode of "double-sided power generation on the board, double-layer ecology under the board, and double-layer breeding between the plates", and realizes double-sided power generation on the board through double-glass modules, which can increase the power generation by 5%-10% Desertification control technology, the implementation of livestock and poultry manure returning to the field to control sand and change soil. Comprehensively realize the multiple benefits of "photovoltaic +" of "on-board power generation, under-board planting, inter-plate breeding, sand control and soil reform, and rural revitalization".
In order to ensure the smooth grid-connected power generation of Kubuqi's 2 million kilowatt photovoltaic sand control new energy project, Inner Mongolia Electric Power Group invested 716 million yuan in the early stage to build the Gushanliang 500 thousand volt power transmission and transformation project and supporting 220 thousand volt line transmission project.
Song Congyue, deputy general manager of Ordos Power Supply Company, said that in the face of the large-scale new energy grid connection in Ordos City, by building a "Tianzig" 500 kV strong backbone grid in the Yellow River Bay, building an intelligent and flexible distribution network, promoting the planning and research layout of energy storage on the grid side, carrying out the integration and intelligent dispatching construction of "source, network, load and storage", enriching the means of peak regulation of the power grid, and continuing to meet the needs of regional new energy development.
The Kubuqi 2 million kilowatt photovoltaic sand control project in Mengxi base is one of the first large-scale wind power photovoltaic base projects to start construction in the country during the "14th Five-Year Plan" period, and it is also the largest single three-dimensional ecological photovoltaic sand control project in the country during the current period built by "central enterprises + private enterprises". The construction of the project has strongly promoted local economic development and employment of farmers and herdsmen. During the construction period, the project attracted more than 1,000 farmers and herdsmen to work. During the operation period, the project will adopt the rural revitalization and mutual aid model of "company + farmer + cooperative", and is expected to steadily absorb 500 people per year to engage in component cleaning, underboard crop planting and management, animal husbandry and breeding, etc.
