Stimulus boost: China launches massive hydropower dam

China has launched the construction of what will be the world's largest hydropower dam, on the eastern rim of the Tibetan Plateau, at an estimated cost of at least $170 billion, the official Xinhua news agency said.
Commencement of the hydropower project, China's most ambitious since the Three Gorges Dam on the Yangtze, was seized by Chinese markets as proof of economic stimulus, sending stock prices and bond yields higher on Monday.
Made up of five cascade hydropower stations with the capacity to produce 300 billion kilowatt-hours of electricity annually, equal to the amount of electricity consumed by Britain last year, the dam will be located in the lower reaches of the Yarlung Zangbo. A section of the river tumbles 2,000 meters (6,561 feet) in a span of 50 kilometers (31 miles), offering huge hydropower potential.
India and Bangladesh have already raised concerns about its possible impact on the millions of people downstream, while nongovernmental organizations (NGOs) warned of the risk to one of the richest and most diverse environments on the plateau.
Beijing has said the dam will help meet power demand in Tibet and the rest of China without having a major effect on downstream water supplies or the environment. Operations are expected sometime in the 2030s.
China's CSI Construction and Engineering Index jumped as much as 4% to a seven-month high. Power Construction Corporation of China and Arcplus Group PLC surged by their 10% daily limit.
'From an investment perspective, mature hydropower projects offer bond-like dividends,' Wang Zhuo, partner of Shanghai Zhuozhu Investment Management, said, while cautioning that speculative buying into related stocks would inflate valuations.
The project will drive demand for construction and building materials such as cement and civil explosives, Huatai Securities said in a note to clients.Shares of Beijing-listed Hunan Wuxin Tunnel Intelligent Equipment Co., which sells tunnel construction equipment, surged 30%. So did shares of Geokang Technologies Co. Ltd., which makes intelligent monitoring terminals.
Cement maker Xizang Tianlu Co. Ltd. and Tibet GaoZheng Explosive Co., producer of civil explosive materials, both jumped 10%.
China's Premier Li Qiang described the dam as a 'project of the century' and said special emphasis 'must be placed on ecological conservation to prevent environmental damage,' Xinhua said on Saturday.
Government bond yields rose across the board on Monday, with the most-traded 30-year treasury futures falling to five-week lows, as investors interpreted the news as part of China's economic stimulus.
The project, overseen by the newly formed state-owned China Yajiang Group, marks a major boost in public investment to help bolster economic growth as current drivers show signs of faltering.
'Assuming 10 years of construction, the investment/GDP boost could reach 120 billion yuan ($16.7 billion) for a single year,' said Citi in a note. 'The actual economic benefits could go beyond that.' China has not given an estimate on the number of jobs the project could create.
The Three Gorges, which took almost two decades to complete, generated nearly a million jobs, state media reported, though it displaced at least a similar number of people.
Authorities have not indicated how many people would be displaced by the Yarlung Zangbo project.
The Yarlung Zangbo becomes the Brahmaputra River as it leaves Tibet and flows south into India and finally into Bangladesh. NGOs say the dam will irreversibly harm the Tibetan Plateau and hit millions of people downstream.
The chief minister of Arunachal Pradesh, Pema Khandu, said earlier this year that such a colossal dam barely 50 km from the border could dry out 80% of the river passing through the Indian state while potentially inundating downstream areas in Arunachal and neighboring Assam state.
