Recently, the winning bid results for planning and design consulting services for pumped storage power stations in the Yalong River Basin in Sichuan Province were announced, marking a new stage in the construction of pumped storage power stations in the Yalong River Basin. The comprehensive advancement of this project will not only significantly improve the level of clean energy utilization in Sichuan Province, but also make a positive contribution to my country's carbon peak and carbon neutrality goals.

The Yalong River Basin Pumped Hydropower Storage Project is one of the key clean energy projects promoted by Sichuan Province. It has a total installed capacity of approximately 11,200MW and is planned to be fully put into operation before 2035. The projects mainly include Lianghekou hybrid, Daofu, Ganzi, Yajiang, Xinlong, Shiqu, Seda, Litang and Yanyuan pumped storage projects. These projects have been included in the Sichuan Province pumped storage demand demonstration report. Among them, the Lianghekou Mixed, Daofu, Ganzi, Yajiang, Xinlong, Shiqu, Seda, and Litang projects are included in the "Yalong River Basin Water, Scenery and Light Integrated Base Plan", and all plans will be approved by 2028. It will be fully put into operation before 2035; the salt source pumping and storage project is the pilot project of the comprehensive utilization project of salt introduction.

As an important energy storage method, pumped storage power stations can play a role in peak shaving, valley filling, emergency backup, etc. in the power system, effectively improving the stability and operating efficiency of the power grid. The construction of the pumped storage energy project in the Yalong River Basin will make full use of the rich water resources of the Yalong River and combine it with advanced engineering technology to build an efficient and reliable clean energy system, which will provide energy structure adjustment and green energy for Sichuan Province and even the country. Provide strong support for development.

The company that won the bid this time was China Power Construction Group Beijing Survey and Design Institute Co., Ltd. It won the first candidate for the planning and design (economic and technical) consulting services for the pumped storage power station in the Yalong River Basin with a bidding price of 32.99 million yuan. PowerChina Beijing Survey, Design and Research Institute Co., Ltd. has stood out in the fierce competition with its rich experience and professional technology in the field of hydropower engineering. In addition, China Power Construction Group Northwest Survey and Design Institute Co., Ltd. and China Power Construction Group Central South Survey and Design Institute Co., Ltd. ranked second and third with bids of 34.57 million and 39.29 million yuan respectively.

As the world's leading power engineering service provider, China Power Construction Group's major survey, design and research institutes have profound technical accumulation and rich project experience in clean energy fields such as hydropower, wind power, and solar energy. This winning bid once again demonstrates PowerChina's strong strength and good reputation in the planning and design of clean energy projects.

Up to now, the Lianghekou hybrid and Daofu projects of the Yalong River Basin pumped storage project have been approved to start construction, the Yanyuan project is undergoing pre-feasibility study work, and the Ganzi, Yajiang, Xinlong, Shiqu, Litang and Seda pumped storage projects have been approved for construction. The storage project is in the planning and site selection stage. The steady advancement of the project is inseparable from the joint efforts of Yalong River Basin Hydropower Development Co., Ltd. and all participating units.

During the project construction process, Yalong River Basin Hydropower Development Co., Ltd. will work closely with Power Construction Group Beijing Survey and Design Institute Co., Ltd. and other units to strictly follow the planning and design plan, scientifically organize the construction, and ensure that the project is completed on schedule with high quality. The completion and operation of the project will greatly improve the utilization efficiency of hydropower resources in the Yalong River Basin, promote the development of Sichuan Province's clean energy industry, and contribute to the realization of the "double carbon" goal.

In the future, as the pumped hydro energy storage project in the Yalong River Basin is fully completed and put into operation, Sichuan Province's power system will be more stable and reliable, and the proportion of clean energy will further increase. This will not only help optimize the energy structure of Sichuan Province and promote the green and low-carbon development of the economy and society, but will also provide useful reference and strong support for the national energy transformation and sustainable development.

The comprehensive promotion of the pumped hydro energy storage project in the Yalong River Basin is an important measure for Sichuan Province to implement the national energy strategy and promote the development of clean energy. Through the construction of this project, it will not only effectively improve the utilization efficiency of hydropower resources in the Yalong River Basin, but also provide a strong guarantee for the stable operation of the power grid, helping my country achieve its carbon peak and carbon neutrality goals. It is believed that with the joint efforts of all parties, the Yalong River Basin pumped hydro energy storage project will be a complete success and will make a significant contribution to the development of clean energy in Sichuan Province and even the country.Editor/Jiang Mingyue
