The Tibetan Plateau is not suitable for large-scale power grid construction

It is now a trend and trend for people to drive into Tibet. The original natural scenery is the rarest pure land in the world, but the dense power poles and large transmission towers often become unsightly and unconformable with the original landscape. With the construction of power grids, these unsightly things will extend to every corner of the Qinghai-Tibet Plateau.

Tibet is not suitable for Jianda Hydropower Station

On November 23, Tibet’s first large-scale hydroelectric power station, the Zangmu Hydropower Station, was put into operation, causing great uneasiness in the Indian media. In fact, the construction of the hydropower station marks the beginning of the Tibetan era of hydropower.

The maximum dam height of the Tibeto Hydropower Station is 116 meters. The normal water storage level of the reservoir is 3,310 meters, and the corresponding storage capacity is 86.66 million cubic meters. The total installed capacity of the power station is 510,000 kilowatts. The installed capacity, reservoir storage capacity, and power generation methods will not have much impact on the ecology and hydrology, but the economic objectives of a single power station operation will certainly be difficult to achieve, and it will inevitably be a multi-level development and adjustment and compensation. System development will inevitably endanger the rivers in Tibet and even the Tibetan Plateau. If the system development thinking remains unchanged, rivers on the Qinghai-Tibet Plateau will not be able to escape.

In addition to the Tibeto Hydropower Station, during the “Thirteenth Five-Year Plan” period, a series of large-scale hydropower stations will be built on the Jinsha River, Lancang River, Nu River and Brahmaputra River, which will form the largest large-scale hydropower project in Shanghai. It is impossible to count how many hydropower stations have been built in Tibet. There are less than 10 50,000 kilowatts and hundreds of small hydropower stations. However, the operation efficiency is poor and the life span is short. From most of the hydropower stations above 3,500 meters in Sichuan, Qinghai and Tibet that I have visited, the glacial period of about 5 months has caused the majority of power station inlet ditches to be congested by ice. The output of hydropower plants is extremely low or even impossible. Power generation, the freezing of the power station system is extremely serious, and the maintenance costs are huge.

Tibet is not suitable for building hydropower stations. First, the Qinghai-Tibet Plateau is a large river originating in Asia. The rivers are mainly fed by glaciers and melt water, and their ability to recharge the lakes is weak. Seasonal differences in hydrology are serious and unstable. The output of power plants is low, the quality of power generation is not high, and the damage caused by freezing and closure in winter is caused. Severe harm to power system is serious. Second, due to the limited value of land and geological conditions in the river valleys, it is difficult for Tibet's rivers to build regulatory reservoirs. The adjustment performance of the power stations will be reduced and their compensation capabilities will be affected. The above two points reduce the technical and economic indicators of the power plant.

Build the power grid greatly damaged the value of the landscape

The Qinghai-Tibet Plateau is the ridge of the earth. It is a highland of water resources and ecosystems and has global significance. Its development is positioned as an ecological industry. It should not develop large hydropower, nor does it require large-scale power construction. It should consider building wind power, solar energy, and other self-powered safeguard systems that can adjust each other. It is not worth the effort to transmit power. The loss caused by the landscape value is enormous.

Tibet has world-class tourism resources. The original natural scenery and ancient ethnic customs are the aspiration of domestic and foreign tourists. Excessive and inappropriate development will weaken the value of destroying tourism resources. Today, it is on some tourist routes and tourist attractions. The dense transmission grids and power poles greatly interfere with people's appreciation of the fun and reduce the value of tourism.
