The wind farm will transmit electricity to the general power grid using a 500 kW ultra-high voltage (UHV) line. The project will thereby contribute to commercialisation of UHV technology, which has already been used in the PRC. In 2018, the Changji-Guquan (1100 kV) line, which is 3,324 km long, was put into operation and connected the Xinjiang Uygur Autonomous Region in the west of the PRC with Jiangsu Province in the east of the country. The line, able to transmit 100 million KWh of electricity every eight hours and 20 minutes, not only reduced the imbalance between the energy surplus west and the energy deficient east of the PRC but also ensured coal savings (30 million tons per year), and reduced emissions of soot (24 thousand tons per year), sulfur dioxide (149 thousand tons per year) and nitrogen oxide (157 thousand tons per year).
“UHV technology will expand the future geography of renewable energy use: the countries producing renewable energy will be able to export it to the regions where alternative energy is not widespread, and because of the difference in environmental conditions,” told the Global Energy one of the authors of the second edition of the “10 Breakthrough Ideas in Energy for the Next 10 Years” report published in 2021. “The regions best suited to wind power generation (Arctic, Central and North Asia, Northern Europe, Central and Northern America, East Africa) and the sun generation (North and East Africa, the Middle East, Oceania, Central and South America) are remote from a lot of large electricity consuming centres. UHV technology can help eliminate this imbalance as it will make possible safe and efficient electricity transmission between countries, regions and continents.”
China remains a global leader in the introduction rate of wind turbines. It accounted for 41% (29.5 GW out of 71.8 GW) of the global installed capacity growth of the onshore wind power plants in 2021, and 82% (17.4 GW out of 21.3 GW) of the offshore wind generators, according to the data of International Renewable Energy Agency (IRENA). The 2021 wind generation volume in China increased by 72% (up to 645 TWh), and its share in the power generation mix raised from 6.4% to 7.6%, according to the Ember research center estimates. However, both figures will be even higher in the coming years given that by early 2022 China had accounted for 19% of the global wind power capacity under construction (180 GW out of 929 GW, according to the Global Energy Monitor).
