The commencement of the ± 800 kV high-voltage direct current transmission project from Gansu to Zhejiang marks an important step forward in China's energy transmission field. This project is not only a key project in the national "14th Five Year Plan" for power development, but also the third ± 800 kV high-voltage transmission project in Gansu province after the introduction of Gansu power into Hunan and Shandong provinces. Its uniqueness lies in the fact that it is the world's first cross regional ultra-high voltage direct current transmission project to adopt flexible direct current transmission technology at both the transmitting and receiving ends, which has milestone significance.

The total investment of the Gansu Electric Power Project in Zhejiang is about 35.3 billion yuan, with a total length of 2370 kilometers. It starts from Wuwei, Gansu in the west and ends in Shaoxing, Zhejiang in the east, passing through six provinces and regions including Gansu, Ningxia, Shaanxi, Henan, Anhui, and Zhejiang. The project is planned to be completed and put into operation before the peak summer of 2026, with a supporting power supply of 15.2 million kilowatts, including 4 million kilowatts of coal-fired power and 11.2 million kilowatts of new energy. This massive transmission capacity will greatly alleviate the pressure of electricity demand in Zhejiang region, while promoting the large-scale development and utilization of new energy in Gansu region.

Specifically, after the commissioning of the Gansu to Zhejiang project, Gansu can annually transmit over 36 billion kilowatt hours of electricity to Zhejiang, with green electricity accounting for over 50%. This means that over 21.2 billion kilowatt hours of new energy electricity will be transported from Gansu to Zhejiang every year, greatly promoting the consumption of new energy. At the same time, this project will replace 6.4 million tons of coal consumption and reduce 17 million tons of carbon dioxide emissions, which is of great significance for promoting national energy structure adjustment and ecological civilization construction.

In addition, the entry of Gansu Power into Zhejiang Province will bring significant economic and social benefits. The project has driven an investment of over 80 billion yuan, which can directly drive the coordinated and rapid development of the upstream and downstream industrial chains, providing more than 24000 job opportunities. While promoting economic development, it has also created more employment opportunities and sources of income for the local society.

For the Zhejiang region, the operation of the Gan Dian into Zhejiang project will greatly alleviate its power supply and demand contradiction. As an economically developed province, Zhejiang's demand for electricity continues to grow, but its local power supply capacity is limited. The completion and operation of the Gan Dian into Zhejiang project will provide Zhejiang with a more stable, safe, and reliable power supply guarantee, meeting its electricity demand for economic and social development.
