Recently, the dam of the Lawa Hydropower Station, the world's highest concrete face rockfill dam designed and constructed by the company, achieved a "double breakthrough": the filling height exceeded 200 meters and the filling volume exceeded 15 million cubic meters, laying a solid foundation for the power station to achieve the goal of commissioning and power generation ahead of schedule.

The Lawa Hydropower Station is an important component of the clean energy base in the upper reaches of the Jinsha River, one of the nine major clean energy bases under the national "14th Five-Year Plan." The dam has a height of 239 meters, a crest elevation of 2,709 meters, and a total filling volume of nearly 17 million cubic meters, making it the world's highest concrete face rockfill dam at present. The entire survey and design process was carried out by Zhongnan Engineering Corporation under the company, the main dam project was constructed by Sinohydro Bureau 12 Co., Ltd., and major construction tasks were undertaken by subsidiary enterprises including Sinohydro Bureau 1, Bureau 4, Bureau 8, and Bureau 11.

The Lawa Hydropower Station dam site is located in a deep canyon on the plateau, characterized by high filling intensity, a short construction period, high seismic intensity, difficult quality control, significant impact from cross-operation, and numerous difficulties in material supply from borrow areas. The dam filling construction is highly difficult and has extremely high technical requirements.

Since the commencement of the project, the Lawa Project Department of Sinohydro Bureau 12 has adhered to Party building leadership, strengthened technological empowerment, enhanced quality control, and promoted high-quality contract performance, striving to build a premium project. The project team adhered to planning first, continuously optimized construction planning, and ensured that daily progress supports weekly targets, weekly progress guarantees monthly plans, and annual planning, phase planning, and special planning complement and reinforce each other. They built a vast working area of over 82,000 square meters, formed an intelligent construction model integrating dam filling, grouting construction, dam material transportation, and borrow area excavation, and systematically applied unmanned roller fleets throughout the entire dam filling process. They pioneered the large-scale use of new energy dump trucks for dam material transportation in cold plateau regions, having successively put into use approximately 90 new energy vehicles and built 3 new energy charging and battery swap stations, providing reference experience for the hydropower industry in constructing world-class projects of the same type on the plateau.

All Party members, cadres, and employees of the project department fully carried forward the plateau hydropower iron army spirit of "fearing hardship but not suffering from it, lacking oxygen but not lacking spirit, and having a higher realm at higher altitude," continuously surpassing themselves and setting new records, driving the dam filling height to exceed 200 meters and the total filling volume to exceed 15 million cubic meters. The monthly filling volume exceeded 1 million cubic meters for several consecutive months, and the monthly rise height exceeded 10 meters, making the Lawa Hydropower Station dam the fastest-rising concrete face rockfill dam in China at present.

The Lawa Hydropower Station has a total installed capacity of 2 million kilowatts. Upon completion, it will provide 8.224 billion kilowatt-hours of clean electricity annually, corresponding to savings of approximately 2.8 million tons of standard coal and reductions of approximately 9.1 million tons of carbon dioxide, sulfur dioxide, soot, and other emissions, which is of great significance for helping the country achieve the "dual carbon" goals at an early date and further implementing the "West-East Power Transmission" strategy.
