Three Gorges Dam Hydroelectric Power Plant
Three Gorges Dam Hydroelectric Power Plant The Three Gorges Dam Project (TGP) is the world's largest hydropower complex project located in one of the three gorges of the Yangtze River: the Xilingxia Gorge in Hubei province, China. The gorge controls approximately one million square kilometres of drainage area and averages a runoff of 451 billion cubic metres annually. China Three Gorges Corporation (CTGPC) acts as the legal entity for TGP and is responsible for the construction, operation and financing of the project. Construction on the Three Gorges Dam was completed in 2008. The dam stands 185m high and 2,309m wide, making it the world's largest hydro plant, well ahead of Brazil's 12,600MW Itaipu installation. A total of 32 main power generators are planned to operate off the dam, of which 12 sets on the right bank and 14 sets on the left were installed in 2006 and 2008, respectively. They were operational in October 2008 and generated a total of 18,300MW. Another six generators are being installed underground and are expected to become fully operational by the end of 2011. These six were added to the project in 2002. The first three became operational in June 2011. The third generator unit (Unit 30) completed a 72 hour test run in July 2011. The first underground unit (Unit 32) began operations in May 2011 and the second (Unit 31) commenced commercial operations in June 2011. Once the additional generators are all installed, the plant will produce 22,500MW of electricity. Three Gorges project The Three Gorges Dam project involves harnessing the Yangtze River, Asia's longest stretch of water, to generate prodigious amounts of electricity. -
Three Gorges Dam in Hubei, China: a Cost and Benefit Analysis
Economic Analysis of Public Policy Professor Yoshitsugu Kanemoto Graduate School of Public Policy, University of Tokyo Final Report Three Gorges Dam in Hubei, China: A Cost and Benefit Analysis Felipe Francisco De Souza Graduate School of Engineering, University of Tokyo Baozhi Gu, Kenji Kurotobi Graduate School of Public Policy, University of Tokyo Yuri Kim Graduate School of Frontier Sciences, University of Tokyo August 2013 Executive Summary Situated on a canyon known as the Three Gorges in Hubei, China, Yangtze River’s Three Gorges Dam is the world’s largest power station in terms of installed capacity (22,500 MW). The project was initiated by the Chinese government in 1994, with the support of different international cooperation agencies, for three main reasons. First of all, it would generate hydroelectricity to meet China’s rapidly increasing demand. Second, the Three Gorges Dam would protect millions of people living along the river from potential floods. And finally, it would transform a 600- kilometre stretch of the fast-flowing river into a smooth navigable waterway for vessels and provide business opportunities to western landlocked provinces. The Chinese government regards this project as a historic engineering, social and economic success, with the design of sophisticated large turbines, and a move toward limiting greenhouse gas emissions. However, the dam has been a controversial topic, the reason why a cost and benefit analysis was developed to understand all possible variables related to this gigantic project and its complicated development process. For the evaluation of major benefit components, special care was taken to understand flood control (and dam’s capacity to control 100 years events); electricity generation (and the reduction of CO2 emissions); and the enhanced shipping capacity (allowing the transit of large quantities of cargos). -
Respective Influence of Vertical Mountain Differentiation on Debris Flow Occurrence in the Upper Min River, China
www.nature.com/scientificreports OPEN Respective infuence of vertical mountain diferentiation on debris fow occurrence in the Upper Min River, China Mingtao Ding*, Tao Huang , Hao Zheng & Guohui Yang The generation, formation, and development of debris fow are closely related to the vertical climate, vegetation, soil, lithology and topography of the mountain area. Taking in the upper reaches of Min River (the Upper Min River) as the study area, combined with GIS and RS technology, the Geo-detector (GEO) method was used to quantitatively analyze the respective infuence of 9 factors on debris fow occurrence. We identify from a list of 5 variables that explain 53.92%% of the total variance. Maximum daily rainfall and slope are recognized as the primary driver (39.56%) of the spatiotemporal variability of debris fow activity. Interaction detector indicates that the interaction between the vertical diferentiation factors of the mountainous areas in the study area is nonlinear enhancement. Risk detector shows that the debris fow accumulation area and propagation area in the Upper Min River are mainly distributed in the arid valleys of subtropical and warm temperate zones. The study results of this paper will enrich the scientifc basis of prevention and reduction of debris fow hazards. Debris fows are a common type of geological disaster in mountainous areas1,2, which ofen causes huge casual- ties and property losses3,4. To scientifcally deal with debris fow disasters, a lot of research has been carried out from the aspects of debris fow physics5–9, risk assessment10–12, social vulnerability/resilience13–15, etc. Jointly infuenced by unfavorable conditions and factors for social and economic development, the Upper Min River is a geographically uplifed but economically depressed region in Southwest Sichuan. -

Hydroelectric Exploitation and Sustainable Development of the Yalong River
UNHYDRO 2004 Beijing HYDROELECTRIC EXPLOITATION AND SUSTAINABLE DEVELOPMENT OF THE YALONG RIVER Chen Yunhua: Professorial Senior Engineer,General Manager of Ertan Hydropower Development Company Ltd. Abstract: The middle and lower reaches of the Yalong River are China’s few river basins with favorable conditions for hydropower development. The abundant water resources of the Yalong have environment-friendly features in all perspectives. With the river running through Ganzi Tibetan Autonomous Prefecture and Liangshan Yi Autonomous Prefecture of Sichuan Province in China’s Southwest, development of the Yalong will greatly promote economic development and social advancement of the minority areas. Only when a river basin is developed and managed by a vigorous and responsible company can a harmony between environment and development be achieved to the maximum extent, and a successful implementation of the strategies for sustainable development be assured. Ertan Hydropower Development Company Ltd. (EHDC) has been authorized by the Central Government to exploit the hydropower resources of the Yalong River. This is a glorious mission and historical responsibility for the Ertaners. EHDC has been making a plan for ecological protection of the river basin with corresponding solutions, which will be demonstrated in the overall planning of the basin. Through construction of Ertan Hydroelectric Project, outstanding achievements and successful experience have been obtained in resident resettlement and environment protection. The development- oriented policies brought practical opportunities to the affected people, and the environment management efforts have started to show their effects. Hydropower development has proved to have more benefits than disadvantages in terms of environmental impacts. With the successful completion of Ertan Project as a new start, EHDC is looking into the future, and will follow the development guideline of “basin, cascading, rolling and comprehensiveness”, and persistently pursue after environment- friendliness and sustainable development.
