Best Practices – Power Generation Hydropower Dam To Fuel Growing Economy Part of a strategic initiative to meet China’s growing demand for renewable energy t 277 meters high, the Baihetan dam will be the tallest dam in China and fourth largest hydroelectric power station in the world when it is completed in 2020. The 18.8 billioncubic-meter storage capacity and 12,000 megawatts of installed capacity place this $13.1 billion megaproject in the company of the famed Three Gorges Dam, the world’s largest hydroelectric power station at 18,200 megawatts of installed capacity. Located on the Jinsha River in Yunnan Province, the Baihetan dam is part of a strategic initiative to meet China’s growing demand for energy by building a dozen cascading power stations on the upper reaches of the Yangtze River and its tributaries. The Baihetan station will complement three other hydropower stations now under construction on the Jinsha—Xiluodu, Wudongde, and Xiangjiaba. Upon completion, the four stations together will have the capacity to produce twice as much electricity as the Three Gorges project. The East China Investigation and Design Institute (ECIDI), part of the China Hydropower Engineering Consulting Group Co., is designing the Baihetan dam from headquarters in Hangzhou, Zhejiang province. Since it was established in 1954, the institute has made numerous contributions to developing hydropower as a sustainable alternative energy source. ECIDI stresses technical advancement and innovation in the support of quality. To ensure continued success, the institute initiated a one-year pilot project as a trial period for using 3D design solutions in 2005. Design of the 1,800-megawatt Longkaikou hydroelectric power station demonstrated that 3D solutions provide a strong advantage for design comparison, computing and analysis, and visualization as well as design productivity and quality. When the Baihetan hydroelectric power station was approved for design in 2006, with construction scheduled to begin in 2009, ECIDI decided to use 3D modeling for design and ProjectWise for collaboration and document management. “Bentley products provided the interoperable applications required by our multidisciplinary team,” said Kaiyu Chen, product manager at Bentley, which provided technical support to the ECIDI project team from ofﬁces in Shanghai. “The intelligent collaboration and managed environment allowed our engineers to cooperate efﬁciently, even though they were distributed across many locations.” A ECIDI began the Baihetan project in September 2006 by drafting the technical standards for 3D design, including seed ﬁle, font, level, workspace, template, ProjectWise structure, and authority. Using Bentley solutions, ECIDI completed the project milestone design and corresponding drawings, power plant and diversion works comparisons, dam position comparisons, complex underground cavern groups design, dam parametric design, complex cut-and-ﬁll design, and integration of 3D geological information and 3D design information. ECIDI discovered that by using interoperable Bentley products, efﬁciency was greatly enhanced, which then provided more time to optimize the design. ECIDI typically compares up to 20 or more dam locations to identify the optimal position for maximizing power generation while minimizing environmental and social impacts. The team evaluated 16 alternatives for the Baihetan dam, a process that took onetenth the amount of time to complete using Bentley applications such as GEOPAK. “With Bentley as our strategic partner, we are conﬁdent that we will complete design of this huge project in 2009,” said Jeffrey Zhang, ECIDI development manager. “We will be applying Bentley technology to more hydroelectric power stations in the future.” The hydroelectric stations currently planned for the Jinsha River and two Yangtze tributaries, known as the Yalong and Dadu rivers, are expected to be completed within 20 years to provide an installed capacity totaling 90.2 million kilowatts. The Baihetan hydroelectric power station alone will increase electricity production in the western region by 5.5 billion kilowatts per hour. The improved availability and reliability of power will enhance economic development in the southwest region of China.
