An extremely challenging power grid project operating under extreme environmental conditions in areas of high altitude, low air pressure, scarce oxygen, severe cold weather radiation, vulnerable ecology and magma fragmentation.

With 16 substations at or above 110kV (including six at 500kV) and 2,738km of transmission lines at or above 110kV (including 1,990km at 500kV), the project marks a historical leap in Tibetan power grid voltage from 220kV to 500kV.

Since operations began, it has over 3.14 billion KWh of clean power supply to sufficiently satisfy the demand of Tibetan people.

The transmission network breaks a number of records, including the highest altitude and largest height difference between transmission towers. It also represents the world’s most advanced power grid technology, filling blanks in grid design at an altitude of over 5,000m, with a height difference of over 400m.

The network has provided 2.2 million local residents with electricity for lighting and heating, as well as for modern convenience such as TV and Internet. It has allowed for an acceleration of the local economy and eco-tourism and the shift to clean energy has reduced the reduced consumption of 500,000 trees for fuel and nine million tons of equivalent coal.ht place embracing a brilliant future
