Construction of Ali-Central Tibet Power Grid Network Project By 2021
to a news item published in the Tibet Business Daily of China Tibet News Network on 29 Nov 2019, the Ali – Central Tibet Power Grid Network project will be completed in 2021.
By then, the main power grids in Tibet will cover 74 counties in Tibet, covering 97% of population.
The Deputy Director LuosangDawa of Ali – Central Tibet power grid network project said that after completion of this project, it will completely end the long history of isolated grid operation in the Ali prefecture and improve the quality and reliability of power supply in Ali prefecture and western Xigaze (Rikaze). This will fundamentally solve the electricity problem of nearly 380000 people.
On construction of this unified and stable power grid, Tibet will realize the main power grid covering 74 counties in Tibet, providing power supply to 97% population. It will help border construction and border area development and strengthen the national defense security. At the same time, it can actively serve the “Belt and Road” construction, create an open channel to South Asia, and achieve infrastructure and mutual interflow with peripheral countries.
According to Luo Gang, the manager of 220 kV proprietor project department of Ali- Central Tibet power grid network project, the six substation master control buildings of Ali-Central Tibet power grid network project have been capped, 2733 foundation excavations have been completed and the completion ratio is 81.56%. The foundation pouring at 2584 foundations have been completed and the completion ratio is 77.11%. The assembling and installation of iron towers is going on in sequence. It is estimated that organizing the towers in 30% of the whole line can be completed by this year end and all the engineering projects are progressing in an orderly manner.
The Central Tibet electricity networking project has already been providing power source guarantee to 3070 small towns. It is a key electricity network project for accelerating the development of electricity in Tibet during the ’13th Five Year Plan’ period. Following the Qinghai-Tibet power network project and the Sichuan-Tibet power network project, the central Tibet electricity network was another ‘super’ project of plateau electricity networking that has broken through the life restrictions and the limit of survival challenges.
It is said that the Central Tibet electricity networking project is consisting of central Tibet – Changdu (Qamdo) power grid network project in Tibet and the Lhasa – Linzhi (Nyingchi) section power supply project of Sichuan-Tibet Railway. The project starts at Mangkang county of Changdu (Qamdo) city and ends at Lhasa city, passing through the four cities of Qamdo (Changdu), Nyingchi (Linzhi), Shannan (Lokha) and Lhasa and 13 counties, having a total length of more than 1900 Km. Since the start of operation of central Tibet power grid network in 2018, it has provided reliable power supply guarantee for the power grid upgradation and reconstruction of 3070 small towns (central villages) in Tibet. At the same time, the voltage level of the power grid in Tibet has been rised from 220 kV to 500 kV and officially entered the era of extra high voltage (EHV) AC /DC Hybrid power grids.
After completion and put it into operation, the central Tibet network project not only provided power guarantee for the overall national development strategy and border security in Tibet, but also further interconnected the main power grids of Tibet with the southwest and northwest power grids and greatly improved the capability of power supply guarantee. At the same time, the electricity network in central and eastern part of Tibet become more stronger, met the power supply needs of the economic and social development of the central and eastern Tibet and the construction and operation of the Lhasa-Linzhi Railway. It effectively promoted the development and utilization of clean water, wind, and light energy in Tibet, and realized the delivery of Tibetan electricity outside.
