China is flexing its engineering muscles yet again with a project that will see this nation outdo its past achievements. 60,000 megawatts of electricity will be generated from the highlands of Tibet, seeing this new project rendering more power than the Three Gorges Dam.
China’s push for clean energy is in full swing
This project further cements China’s intent to focus on clean energy and its desire to move away from coal and fall more in line with climate expectations. A large amount of the energy generated would serve Tibet and increase development in this remote region. China is also a proud nation, and so undertaking the construction of projects of this nature signifies its strength and engineering acumen.
Skeptics are wondering as the scale of this hydro plant is not small. The dam is being built as a cascade of five power stations situated on a steep drop in the river and not just as one wall, which will, of course, give rise to a challenging set of engineering demands that will need to be managed skillfully.
How China’s new hydro plant will harness the vertical drop
China’s newest hydro plant will be situated on a site that lies on the Yarlung Tsangpo (which becomes the Brahmaputra downstream), in an area where the river dips roughly 2,000 meters over roughly 50 kilometers. That immense decline offers vast hydropower potential, which will see this plant able to generate a large amount of power even when water levels are lower than usual.
Having the stations staggered in this manner will enable each one to gather energy at varying heights to optimize the efforts across the gorge. This area is also prone to landslides and earthquakes, so going about the construction in phases will be key in reducing structural stresses and any geological surprises that may arise.
The risks involved in a project of this magnitude
The terrain is unforgiving, and so undertaking cooperation in this area will be demanding to say the least. Steep slopes and seismic activity will need to be contended with. The immense weight of the reservoirs might place heightened stress on fault lines, and the extreme temperatures will also be harsh on the materials used. Maintenance will not be easy, given the high altitude, and the logistics involved in doing so will also need to be overseen cleverly.
The impact on the environment will also need to be monitored closely, as altered flows could affect sediment transport and seasonal floods. Aquatic and terrestrial ecosystems might be damaged, and downstream countries like India and Bangladesh will monitor any changes in flow, which might affect fisheries or irrigation, which could have a devastating toll on the livelihoods of some of their citizens.
How China’s hydro plant might impact neighboring countries
Sovereignty is also a debate that has been sparked by the announcement of this project, with neighboring countries worried that China will control upstream flows. This has been expressed by India in particular, with Chinese officials claiming that they have no intention of impacting downstream states.
China has set aside more than 1.2 trillion yuan (over USD $160–170 billion, depending on exchange rates) for the cascade complex. That kind of money will invite attention of all kinds, and any mishaps will be under heavy scrutiny. Beyond the financial implications, diplomatic matters swirl around this hydro plant being built, and any infringement might result in a diplomatic skirmish that could see this state, distrusted by a sizable portion of the world, viewed in a worse light.
A lot may be on the line for China, which views this hydro plant as more than just a means to cleaner energy but as another statement of dominance and engineering prowess. The completion of this cascade complex may also be something for other states to emulate should everything go according to plan.
