Recently, multiple engineering bureaus under China Railway Construction Bureau Group have won a series of major projects across the country, spanning diverse fields such as mining, intercity rail transit, grid energy storage, and new energy charging facilities. The total value of the five projects exceeds 9.6 billion yuan, solidifying its core advantages in traditional infrastructure while demonstrating rapid expansion into the new energy sector.
First: Guizhou Weng'an Bauxite Mine Project: A 4.875 Billion Yuan Deal, with Mining Infrastructure as the Core Investment
The largest project by value is located in Qiannan Prefecture, Guizhou. The Banzhai mining area construction and development project for the Weng'an County Banzhai Jianzhong bauxite mine was won by China Railway 23rd Bureau Group Co., Ltd. with a bid of approximately 4.875 billion yuan. The mining area is situated at the border of Yuhe Township and Jianzhong Town in Weng'an County, covering 2.9384 square kilometers with an annual production capacity of 100,000 tons. It uses a combined open-pit and underground mining method, divided into two mining sections and six bauxite ore bodies. The project has already obtained approval from the provincial development and reform commission and the mining license, with all procedures completed. Notably, the 4.8 billion yuan bid for a 100,000-ton annual output indicates that the funds are not concentrated on the extraction process. The core investment is focused on mining infrastructure, mineral processing system construction, and underground tunneling, making it a typical large-scale mining infrastructure plus development integrated project. This demands high capability from the construction company in underground engineering and industrial supporting facilities.
Second: Fujian Quanzhou-Xiamen-Zhangzhou Intercity R1 Line: 14th Bureau Takes the Lead, Securing a 2.4 Billion Yuan Core Section in Zhangzhou
New progress has been made in the intercity backbone project of the Southern Fujian region. For the civil engineering SG3 section of the Zhangzhou segment of the Quanzhou-Xiamen-Zhangzhou intercity railway R1 line, China Railway 14th Bureau Group Co., Ltd. ranked as the first candidate for the bid, with a bid price of about 2.403 billion yuan. The Zhangzhou section of the R1 line starts at the border of Wenshanxia and Xiamen, passing through the Taiwan Investment Zone, Longhai District, High-tech Zone, Longwen District, and Xiangcheng District, ending at Jintang Station, with a total length of 51.8 kilometers. The line includes 14.6 kilometers of underground sections, about 7.5 kilometers of mountain tunnels, and about 29.7 kilometers of above-ground sections, with 11 stations (including the reserved Zini Island Station), along with the Jinfeng Vehicle Depot, Emergency Command Center, and two main substations. The project adopts a double-track intercity railway standard with a design speed of 160 km/h, a minimum distance between lines of 4 meters, a general curve radius of 1,500 meters, and a maximum gradient of 30‰. The SG3 section, with an estimated budget of about 2.9 billion yuan, is one of three civil engineering sections in the Zhangzhou segment. Its construction scope includes civil works for stations and intervals, traffic diversion, road restoration, greening relocation, pipeline relocation, and large-scale temporary works. As a core commuter corridor for the Xiamen-Zhangzhou-Quanzhou metropolitan area, the R1 line will significantly reduce travel time between the three cities, directly boosting coordinated development and integration in southwestern Fujian.
Third: Gansu Yumen Energy Storage Project: A 1.061 Billion Yuan EPC Contract for Grid-Side Peak Shaving
Supporting infrastructure is being added to the new energy base in Northwest China. The EPC general contract for the Yumen Hongda Jianglai 300 MW/1200 MWh energy storage project was awarded to a consortium led by China Railway Construction Electrification Bureau Group Northern Engineering Co., Ltd. and China Railway First Survey and Design Institute Group Co., Ltd., with a bid price of approximately 1.061 billion yuan. Located in the Qiduntan Gobi area of Yumen City, Jiuquan, the project includes the construction of the energy storage station, a 330 kV substation, transmission lines, and retrofitting of terminal equipment, using an integrated EPC model covering survey, design, equipment procurement, and construction. The project is scheduled to start in August 2026, connect to the grid by the end of April 2027, and be completed by the end of May 2027, with a tight construction timeline. With 300 MW power matching 1,200 MWh capacity, the system can discharge at full power for 4 hours, a typical configuration for grid-side independent energy storage. The Hexi Corridor is a core production area for wind and solar power in China, and large-scale energy storage projects can effectively enhance the absorption capacity of new energy, with significant peak-shaving and industrial value. The consortium has a clear division of labor, with the First Survey and Design Institute handling survey and design, and the Electrification Bureau handling construction and installation, fully leveraging their professional synergies.
Fourth: Distributed Charging Infrastructure: A 922 Million Yuan Package for 450 Supercharging Stations
The new energy supporting infrastructure sector continues to expand. The Phase I EPC general contract for the new energy supercharging station project was won by a consortium of China Railway 15th Bureau Group Shanghai New Energy Development Co., Ltd. and Zhongyu Design Co., Ltd., with a bid price of about 922.4 million yuan, basically matching the planned investment for Phase I. The project will build 450 supercharging stations and supporting facilities in batches, using a design-build integrated EPC model. While the construction of charging stations is accelerating across the country, a single-batch package of 450 stations is relatively rare, showcasing the company's overall delivery capability in the distributed new energy infrastructure sector. China Railway 15th Bureau Shanghai New Energy Company has previously accumulated rich experience in this sector, and this joint bid with a design partner further strengthens its layout in urban new energy supporting facilities.
Fifth: Hebei Changli Energy Storage Project: A 354 Million Yuan Deal, Another Independent Energy Storage Project
The energy storage market in North China continues to expand. The design and construction general contract for the Goldwind Zero Carbon Qinhuangdao Changli 100 MW/400 MWh independent energy storage project was won by a consortium of China Railway 14th Bureau Group Electrification Engineering Co., Ltd. and Zhejiang Mechanical and Electrical Design and Research Institute Co., Ltd., with a bid price of about 354 million yuan. The project covers about 43 acres and also uses a 100 MW power matching 400 MWh capacity configuration with a 4-hour duration, serving as a key peaking facility for the Hebei regional power grid.
Industry Insight: Traditional Business as a Stabilizer, New Sectors Accelerate Growth
Reviewing the five projects clearly reveals the business layout logic of China Railway Construction Bureau Group. The 23rd Bureau deepens its traditional strengths in mining infrastructure, securing a nearly 5 billion yuan deal. The 14th Bureau makes strides in both intercity rail transit and electrified energy storage. The Electrification Bureau and the 15th Bureau continue to push into emerging sectors like new energy storage and charging facilities. Structurally, traditional infrastructure such as mining and railways accounts for over 70%, still forming the basic performance foundation. New energy businesses like energy storage and charging stations are continuously expanding, showing strong growth momentum. Overall, while consolidating their core competitiveness in traditional infrastructure, the engineering bureaus under China Railway Construction Bureau Group are accelerating their expansion into new energy and new infrastructure fields. The business structure is being continuously optimized, clearly adapting to the pace of industry transformation.
