Core Insights - The Guangxi Fangchenggang offshore wind power demonstration project has officially commenced operations, marking it as China's first offshore wind project with a fully embedded rock foundation, providing a replicable model for offshore wind development in rocky marine areas [1][3] Project Overview - The project, led by Guangxi Energy Group, is located in the sea area south of Fangchenggang and consists of two sites (A and F) with a total installed capacity of 1.8 million kilowatts and a total investment of approximately 24.5 billion RMB [2][3] - The A site alone is expected to generate around 2.06 billion kilowatt-hours of clean electricity annually, sufficient to meet the basic electricity needs of over 2 million urban households, while saving approximately 620,000 tons of standard coal and reducing carbon dioxide emissions by about 1.64 million tons [2][3] Technological Innovations - The project utilized innovative construction techniques due to the unique geological conditions of the rock foundation, including a suspended pile method to ensure precision and verticality, large-tonnage impact drilling, and factory-based grouting for efficiency [3] - These innovations have led to several industry records, including the fastest completion of a single wind turbine's rock foundation in 20 days and the installation of a turbine in just 40 hours [3] Industry Impact - The ongoing development of the project has attracted multiple offshore wind equipment manufacturing projects to Guangxi, with an expected industrial investment of around 20 billion RMB in 2024 alone [3] - The Chinese government has identified five major offshore wind power bases, including the Beibu Gulf, as part of its "14th Five-Year" renewable energy development plan, with Guangxi planning nine offshore wind farms with a total capacity of 23.5 million kilowatts [3][5] Market Position - As of December 2024, China is projected to have over 40 million kilowatts of offshore wind power capacity, maintaining its position as the global leader in this sector, supported by a comprehensive technology and industry chain from development to operation [5]
