BEIJING - An expansion project for a power converter station that will allow power to be transmitted from Northeast China to North China has been completed, the State Grid Corporation of China said Tuesday.

The project will allow the station to transfer up to 3 million kilowatts of power, making the station the world's largest direct-current back-to-back power station, the SGCC said.

The expansion will improve Northeast China's ability to transfer power to grids in the cities of Beijing, Tianjin and Tangshan and improve the allocation of wind power generated in the northeast, the company said.

Northeast China has abundant wind sources. The company has predicted that the region's installed wind power capacity will eventually reach 24.34 million kilowatts, accounting for more than 17 percent of its total installed capacity.
