Power grid interconnection project facilitates remote southwest Chinese township

A 35kV power grid interconnection project formally started operation in China's Dulongjiang Township, which will provide stable and reliable power to local people by connecting the township with the main grid of China Southern Power Grid.

Dulongjiang Township, located in southwest China's Yunnan Province, is home to Derung minority people. It used to be one of China's least developed regions.

Due to the blocking of high-altitude mountains, the power supply in Dulongjiang mainly relied on small hydropower facilities for a long time. To solve the power problem, electric workers built a 52-kilometer-long overhead line across the local Gaoligong Mountain, connecting the independent power grid of Dulongjiang to the large power grid.

"After connecting to the large power grid, the power supply capacity of Dulongjiang has been enhanced by 10 times, ending the long-isolated grid operation in the township, and meeting the long-term development of rural industries. At the same time, the original independent power grid and the large power grid are interconnected to form a 'dual power supply' structure. Even if it is damaged by natural disasters such as mudslides, the grid can still maintain a stable power supply," said Li Qingjiang, general manager of the infrastructure department of China Southern Power Grid Corporation.

This is the third upgrade on Dulongjiang's power supply system. As early as 2012, every household in Dulongjiang Township had access to electrical power. By 2014, the first and only independent 20 kV power grid in China was built in the township, supporting the local poverty alleviation process. With the rapid development of processing industry and tourism and the improvement of living standards, the interconnection of power grid this time will completely meet the needs of medium- and long-term economic development of the township.
