Mengdigou Hydropower Station on the Yalong River
The main project officially started
Recently, another major project of the Yalong River Basin Water, Scenery and Solar Integration Base has been launchedThe main project of the Mengdigou Hydropower Station on the Yalong River officially started construction, the power station has entered a new stage of engineering construction.
Mengdigou Hydropower Station is located on the main stream of the Yalong River at the junction of Ganzi Prefecture and Liangshan Prefecture in Sichuan ProvinceIt is the largest hydropower project in the Yalong River basin since the 14th Five-Year Plan. The power station is invested and developed by the hydropower development in the Yalong River Basin, with a total investment of about 34.8 billion yuan and a capacity of 2.4 million kilowatts. The power station has an annual power generation capacity of 10.4 billion kilowatt hours, and plans to generate electricity from the first unit in 2031 and all units to be put into operation in 2032.
After the completion of the power station, the annual amount of clean electricity generated will be enough to meet the needs4.75 million householdsThe annual electricity consumption of Sichuan households can save about standard coal3.2 million tons, reduce carbon dioxide emissions about8.4 million tons。The accelerated construction of the project will play an important role in ensuring the high-quality development of the clean energy industry and the rural revitalization of ethnic areas along the Yalong River.
Speed up the Yalong River basin
Construction of water, wind and solar integration base
Serve the national "dual carbon" goal
The Yalong River is rich in hydropower resources, rich in new energy resources such as wind and solar energy, and has strong complementarity between hydropower and wind and solar energy. The Yalong River Basin Water, Wind and Solar Integration Base is a large-scale clean energy demonstration base planned and constructed by the state, which plays a very important role in Sichuan, as an important national hydropower base, to better guarantee the national power supply and serve the national energy strategy. Mengdigou Hydropower Station is the fifth-level hydropower station planned for the hydropower from Lianghekou to Kara River in the middle reaches of the Yalong River, and plays a key role in the cascade hydropower development in the Yalong River Basin.
Mengdigou Hydropower Station is located at the junction of Ganzi Prefecture and Liangshan Prefecture in Sichuan Province.
on the main stream of the Yalong River.
At present, most of the cascade hydropower stations in the middle and lower reaches of the Yalong River have been put into operation or started construction, the upstream wind and solar resources are abundant, the planning and construction of hydropower supporting transmission channels and power grids are relatively clear, and some transmission channels have been put into operation or will be completed and put into operation.
Hydropower is the core of the basin regulation capacity and the key to the construction of the integrated base, and the development and construction of the integrated water, wind and solar base should be led by the main body of hydropower development, which will help to implement the main responsibility of the base and accelerate the development and construction of the base. At present, hydropower development in the Yalong River basin has been put into operation, and hydropower and new energy installations are near21 million kilowatts。By 2035, the installed capacity of renewable energy in the Yalong River Basin Water, Wind and Solar Integration Base will reach78 million kilowatts, the average annual power generation is about200 billion kWh, which is equivalent to saving standard coal60 million tons, reduce carbon dioxide emissions about1.600 million tonsThe carbon reduction benefits of green power are extremely significant.
Overcome "inconvenient transportation, poor construction environment,
complex geological conditions" and other multiple challenges
Promote the construction of the project in an orderly manner
The middle reaches of the Yalong River, where the Mengdigou Hydropower Station is located, has a deep valley and steep valley slopes. Power stationThe construction environment is harsh, the construction site layout is difficult, and it is also facing ice and snowExtreme weather disastersand dangerous rock avalanches, etcGeohazard riskThe project site lacks a stable power supply and communication network, and the preliminary construction starts from scratch.
In September 2021, the preliminary construction of the Mengdigou Hydropower Station project started. In the face of a series of engineering construction problems, Yalongjiang Company and all participating units vigorously promoted it"Build dreams and move forward".Preliminary engineeringLabor competitionCarry out "rival competitions" such as safety, environmental protection, quality, and progress every quarter, and carry out special evaluations of key construction projects every month.
Innovative application of construction technology, adoption"Whole-process AI real-time precision control system"., improve the construction environment, improve the quality of the project and the efficiency of the construction. At the same time, the implementation of the whole funnel for the first time"Emergency water transportation of key materials".It effectively solves the problem of material and personnel entering the site.
After more than 2 years of preliminary construction, Mengdigou Hydropower Station completed the investment of 3.5 billion yuan in fixed assets, realized the diversion tunnel project started on schedule, completed the external traffic, on-site traffic and other projects, built 78 kilometers of new roads, and built 7 new bridgesRemarkable results have been achieved in flood control, forest fire prevention, and environmental protection.
At present, the hub area of the power station has fully realized water, electricity, access, communication and site levelingDesign, supervision, testing and testing and other on-site institutions have been established;The organization of the construction units in the site is sound, the staffing is reasonable, the resource investment meets the needs of the project construction, the bidding and design report of the dam project and the water diversion power generation system project have passed the review, and the project construction is progressing in an orderly manner.
Implement "1+N" intelligent construction management
Create a "dual-intelligence integration" in the construction of hydropower projects
A new benchmark
With the upgrading of hydropower development in the Yalong River basin to digital management and intelligent construction, Yalong River Company will focus on the Mengdigou Hydropower StationImplementation of "Infrastructure Management 30 version", and make every effort to create a new benchmark for hydropower project construction.
First of allStrengthen the "1+N" intelligent construction management systemThrough the construction of a digital command platform, the digital management of design, progress, quality, safety, environmental water protection, water transportation and other businesses will give full play to the advantages of all parties involved in the construction and realize multi-party collaborative operation. Secondly, comprehensivePromote the digital command platform for engineering, and constantly strengthen the project management means, to achieve "a map of engineering construction" monitoring. At the same time, the integration of information systems such as forest fire prevention, quality evaluation, and digital construction sitesRealize the interconnection and interoperability of engineering data.
The accelerated construction of the project will accelerate the rural revitalization of ethnic areas along the Yalong River.
It has an important role in guaranteeing.
In the next step, Yalongjiang will resolutely implement the main responsibility of quality, continuously improve the process, equipment and technology, and promote the construction of the project with high standards and high qualityThe Mengdigou Hydropower Station will become a new benchmark for the integration of "intelligence + intelligent manufacturing" in hydropower project construction. At the same time, we will further give full play to the role of the project in stimulating local economic and social development, transform resource advantages into economic development advantages, and help improve local transportation, communication and other infrastructure conditions through new roads, tunnels, bridges and communication base stationsPromote the revitalization of rural areas in ethnic areas.
