China: Work on China Southern Power Grid's $3.59 B (24.25 billion yuan) Wudongde DC project, the world's first multi-end flexible ultrahigh voltage direct current power transmission (UHVDC) project, is progressing steadily and expected to start operations by 2020, a company official said.
The project spans 16 cities in South China, three power converter stations in Kunming, Yunnan province, Liuzhou in the Guangxi Zhuang autonomous region, and Huizhou in Guangdong province and power transmission lines traversing 1,452 km.
When completed, the project is expected to bolster the clean energy requirements of the Guangdong-Hong Kong-Macao Greater Bay Area. In addition, it will transmit another 20 billion kWh of clean power every year from Yunnan province and Guangxi to the Greater Bay Area.
"Compared with the more frequently used 500 kV high voltage direct current power transmission (HVDC), the company decided on 800 kV UHVDC for higher power capacity and more stable transmission to meet the growing power demands of the Greater Bay Area," said Zhang Yan, deputy general manager for the Kunming's operations of the Wudongde DC Project.
Earlier in March, the company said it will invest over $25 B (170 B yuan) to support grid construction in the Pearl River Delta, China's major economic hub covering Guangdong's capital city Guangzhou, Shenzhen and many other cities in South China.
