CHONGQING - China plans to build a 525-MW hydropower station on the Wujiang River, a tributary of the Yangtze River, in Southwest China's Chongqing municipality.

The Baima project, the last of a cascade of hydropower stations on the section of the Wujiang River in Chongqing, has gotten the green light from the National Development and Reform Commission, China's state planning agency, the Chongqing Municipal Commission of Development and Reform said Monday.

The project, in Baima township of Wulong district, is expected to involve an investment of 10.2 billion yuan ($1.6 billion), it said.

With a power-generating capacity of 525 MW, it is expected to generate 1.76 billion kwh of electricity a year, and help improve the shipping service along the Wujiang River.

More than 5,000 local residents will be relocated to make room for the project.
