Clean Energy

Over the past 60 years, BJEC has organized and participated in the water resources investigation and planning of the Yellow River, Yongding River, Juma River, Chaobai River, Hanjiang River, Nujiang River, Tongtian River, Gangqu River, Naqu River and other rivers; has completed the whole-process investigation and design works for Liujiaxia, Sanmenxia, Fengning, Ankang, Shiquan, Xihe, Xunyang, Dachaoshan, Dahuaqiao, Suwalong, Quxue, Tianhuaban, Tukahe, Jisha, Xiangcheng and Mengyejiang conventional hydropower projects; and has conducted the investigation and design works for large hydropower projects including Maji hydropower station (4,200 MW), Songta hydropower station (3,600 MW), and Yabiluo hydropower station (210 0MW), and dozens of large- and medium-sized hydropower projects in Yunnan, Sichuan, Shaanxi, Tibet, Qinghai, Xinjiang and other provinces. The projects carried out by BJEC cover more than 20 provinces or autonomous regions in China and more than 20 overseas countries and regions, with the total installed capacity of 22,000 MW, in which 6,000 MW installed capacity has been completed.

BJEC has mastered the key technologies for conventional hydropower project design, including flood discharge and energy dissipation by end-flared pier combined with energy dissipater, deep sliding stability of complex foundation, roller compacted concrete damming, high slope treatment, high asphaltic concrete core rockfill dam, new concrete mineral admixture, and design of large-sized underground caverns based on the technical breakthrough and project research of Liujiaxia, Ankang, Dachaoshan, Dahuaqiao, Quxue, Suwalong and other large hydropower projects.

Asahan No.1 Hydropower Station in Indonesia: The World’s Largest Ground-mounted Selfsupporting Steel Surge Tank as of Dec. 2021 (overseas project)

Indonesia’s Asahan No.1 Hydropower Station is located in North Sumatra, Indonesia. The project owner is BAJRADAYA SENTRANUSA in Indonesia. China Huadian Engineering Group is the EPC contractor and has investment holdings. BJEC undertook the feasibility study report, construction bidding, and detailed construction drawing investigation and design, provided technical consulting, construction technology and management consulting, monitoring design, etc. for civil construction, mechanical and electrical equipment installation, hydraulic steel structure equipment installation of the power station. The project’s construction commenced in December 2006, completed and put into operation in August 2010.

Asahan No.1 Hydropower Station Project is designed for power generation, with 2 units, single unit capacity of 90MW and total installed capacity of 180MW. The annual guaranteed power generation is 1.175 billion kw/h. The design head of the power station is 163.5m, and the design flow is 125.8m3/s. The dam is a concrete gravity dam with a crest elevation of 907.00 meters, a height of 39 meters and a length of 71 meters. The waterways are located in the left bank of the river, mainly composed of the power intake, the headrace tunnel, the surge tank and the penstock. The power house is located on the left bank of the river, composed of main and auxiliary power houses.

The Asahan No.1 Hydropower Station is the first large-scale project in Indonesia whose construction was resumed after the 1998 economic crisis, and it posed a great challenge to BJEC in terms of technology and construction. After more than three years of strenuous work, BJEC’s engineering team managed to solve technical challenges such as treatment of tunnel collapse, large scale steel surge tank, high head and large flow energy dissipation valve.
