陕西首个规模化混塔风电项目并网发电

Group 1 - The Guoneng Jia County 50 MW wind power project has successfully connected its first 6.25 MW wind turbine to the grid, marking a breakthrough in large-scale mixed tower wind energy development in Shaanxi [2][3] - The project utilizes a super high mixed tower structure with a hub height of 160 meters and a rotor diameter of 220 meters, designed to generate approximately 110 million kWh of green electricity annually, saving 32,400 tons of standard coal and reducing CO2 emissions by 88,700 tons and SO2 emissions by 89,300 tons [3] - This is the first large-scale application of 160-meter mixed tower technology in Shaanxi, with a construction process that has achieved a significant reduction in assembly errors and waste rates compared to industry standards, setting new records for renewable energy construction in the region [3] Group 2 - The project is expected to achieve full capacity grid connection by the end of the year, which will help adjust the local power grid's structure, optimize resource allocation, and promote employment and the development of the tertiary industry [4] - The project site in Jia County benefits from an average annual wind speed of 6 m/s and over 4,000 effective wind hours, along with a usable area of over 3,000 square kilometers, making it one of the richest regions in wind resources in Shaanxi [4]
