In late September 2021, the first unit of the 295-metre Lianghekou hydropower station, which was one of the 22 level power stations on the Yalong River approved by China’s National Development and Reform Commission in September 2014, came into operation in Yajiang county of Sichuan Province.
The remaining five units are expected to be commissioned by 2023.
Designed by the state-owned power company Chengdu Engineering Corporation, the Lianghekou hydropower station is China’s highest and the world’s second highest hydropower station. It has the world’s deepest reservoir, 285 metres. The power station’s intake tower is 115 metres.
It is estimated that the hydropower station can generate 11 billion kilowatt hours of electricity annually. After completion, it is expected that the dam will reduce raw coal consumption by 13.3 million tons and carbon dioxide emission by 21.3 million tons per year.
The Lianghekhou dam has impacts on the Tibetans who live as far as 100 kilometres away in the upstream of the Yalong River that originates in Tibet-Qinghai plateau.
It is believed by Tibetan right activists that once it is fully completed by 2023, the Lianghekou dam will drown ancestral homes, revered Buddhist monasteries, fertile crops and sacred mountains such as Palshab Drakar. It has been reported that about 6,000 people across four counties were relocated due to the project. The relocated people had received around 300,000 yuan (then US $ 44,000) as compensation.
Furthermore, Sichuan where the dam is located, is regarded as a hotbed of seismic activity. The 2008 earthquake that killed 87,000 people, injured 370,000, and rendered 5 million homeless had its epicentre in Wenchuan county which is a few hundred kilometres from Lianghekou. Some suspect that the earthquake was because of water pressure exerted by dam reservoirs.
A string of dams on the rivers originating from Tibet Autonomous Region (TAR), as the Tibetan rights activists believe, change water flow, create new lakes, disturb local ecosystems and also stop the flow of silt which makes agricultural land fertile.
It is also estimated that between 1990 and 2015 at least a million people have been relocated from Tibet to make way for mining ventures and hydropower projects.
In the past, protests held by the Tibetans against hydropower projects were handed strongly by local authorities. In 2009, it was reported that six women were shot by the Chinese security forces. They were demonstrating against a forcible relocation in Yajiang, Ganzi.
In 2010, reports said Chinese authorities had clamped down on protests against dam building and mining at Naglha Dzamba mountain that is worshipped by many in TAR.
That year, leading Tibetan environmentalist Karma Samdrup, founder of the Three Rivers Environmental Protection Group, was sentenced to 15 years of imprisonment.
According to reports, Karma was detained in 2009 when he tried to secure the release of his two brothers, Chime Namgyal and Rinchen Samdrup, who were imprisoned for their efforts to conserve wildlife in Chamdo.
Then, in 2016, 20 Tibetans were arrested for protesting the construction of a dam on Lancang (Mekong) River in Dechen county in southeast TAR.
Furthermore, it is widely believed that the hydroelectricity generated from the hydropower plants in Tibet are largely transferred to the industrial cities of China.
Even dam construction does not provide jobs to too many local Tibetans, as the power companies largely bring in employees from outside TAR.
Contrary to what Tibetan rights activists, representatives of the Tibet government-in-exile, and several foreign scholars have been saying, the Chinese media and the state authorities portray a picture of development and ecological success of the TAR.
In the last 70 years, the GDP of Tibet has soared past ¥ 190 billion (about US $ 29.3 billion) in 2020 from ¥ 130 million (about US $ 20.65 million) in 1951. Average per capita disposable income of rural residents in Tibet in 2020 was ¥ 14,598 (US $ 2,271), while that of urban residents was ¥ 41,156 (about US $ 6,361).
Some Tibetans are expected to receive around ¥ 10,000 (about US $ 1551.18) every year in subsidies for protecting forests and patrolling the border. Further, it is claimed by the local CPC leadership that since 2016, 700,000 ecological jobs have been provided to local people.
The TAR has more than 60 laws regulating the environmental protection, and around 45% of the area is under protection within ecological “red lines”. The TAR has built 47 natural reserves which occupy more than 34% of the total area of the region. In July 2021, the Chinese President Xi Jinping, the first President to visit Tibet in 30 years, went to the Nyang River Bridge to inspect the ecological preservation in the basin of the Brahmaputra and its tributary Nyang river. Xi also stressed on the need for high quality development in Tibet under the leadership of the CPC.
Tibet has about 200 million kilowatt-hours of water resources , which is 30% of entire China. But by the end of 2017, the total installed hydropower capacity in Tibet was only 1.77 million kilowatts which is much less than the total installed hydropower capacity in China that had reached at about 341 million kilowatts. This accounts for less than 1% of the available technically exploitable quantity.
However, in recent years, to promote hydropower, Tibet’s local government has signed various cooperation agreements with major state-owned power companies, such as China Huaneng Group, China Datang Corporation, PowerChina, and the China Three Gorges Corporation.
As China is struggling to maintain balance between electricity demand and supply , and many parts of its northern provinces are facing water shortage, it is likely to tap more waters from the rivers originating from Tibet to generate hydroelectricity and fulfil water-related demands.
This means that more hydro-infrastructure would be built in the TAR whose impact on the local population is a matter of empirical study.
