China, Beijing: The world’s first ultra-high voltage flexible direct current (UHVDC) transmission project commenced construction on Monday, its operator State Grid Corporation of China, the country’s largest power utility firm, announced. The Gansu-Zhejiang ±800 kV UHVDC Transmission Project will enable the transmission of over 36 billion kWh of electricity annually from Gansu to Zhejiang once completed, with more than half generated from renewable energy sources.
The project, with a rated capacity of 8 million kW and a total investment of about 35.3 billion yuan ($4.82 billion), passes through six provincial administrative regions: Gansu, the Ningxia Hui autonomous region, Shaanxi, Henan, Anhui, and Zhejiang provinces. It is 2370 km long, with converter stations being constructed in Wuwei, Gansu, and Shaoxing, Zhejiang.
The project could facilitate the large-scale development and utilization of clean energy in Gansu, optimizing its energy supply structure, and increasing the proportion of green electricity consumption. After being put into operation, it is expected to promote the consumption of over 21.2 billion kWh of new energy electricity in the Northwest region yearly, replace 6.4 million tons of coal consumption, and reduce carbon dioxide emissions by 17 million tons.
The State Grid’s annual grid investment surpassed 600 billion yuan ($83 billion) for the first time this year, 71.1 billion more than in the previous year. The additional investment is primarily allocated to the construction of ultra-high voltage power transmission projects, strengthening the connection between county-level grids and the main grid, and upgrading grid digitalization and intelligence.
