Floating offshore wind accelerates, Taichung Port expansion becomes critical bottleneck for 2032 grid connection

The Ministry of Economic Affairs officially released the draft of the "Floating Offshore Wind Power Demonstration Project" early this month, planning to complete grid-connection operations by the end of 2032 as a key milestone in the government's promotion of green energy transition. The draft explicitly stipulates that floating platforms will replace traditional fixed foundations to adapt to the characteristics of Taiwan's territorial waters, where depths exceed 60 meters, allowing wind turbines to be installed further from the coast in areas with better wind conditions. This move is not only expected to increase power generation efficiency, but also aligns with the long-term target set by the Renewable Energy Development Act to reach 5.5 GW of installed offshore wind capacity by 2025. Meanwhile, the Ministry has requested all relevant units to complete the supplier selection announcement by the end of the year, demonstrating that the government is accelerating the bidding procedures to shorten the time window for technological verification and commercialization.

However, the transportation and assembly of floating wind turbines place demands on port facilities that far exceed those of traditional land-based or fixed-bottom offshore wind turbines. Jiang Mao-hsiung, Dean of the College of Engineering at National Taiwan University, pointed out that the reserved space at the Port of Taichung is already clearly insufficient. If expansion or re-planning is not carried out in advance, future large-scale floating wind power projects will face bottlenecks in loading and launching. The Port of Taichung currently focuses on containers and general bulk cargo, lacking sufficient deep-water berths and heavy-lift cranes. To accommodate floating platforms exceeding 150 meters in length and weighing thousands of tons, investments of billions in infrastructure will be required, along with the simultaneous upgrading of onshore storage and logistics management systems.

In contrast, although the Port of Taipei in the north and the Port of Kaohsiung in the south possess better deep-water conditions, both are adjacent to international airports, and flight takeoff and landing height restrictions may hinder the assembly operations of large wind turbine components. During the assembly stage, the blades and towers of floating wind turbines often require high-altitude lifting equipment. If flight paths are restricted, related operations can only be conducted during off-peak hours, which will significantly reduce construction efficiency. Dean Jiang further explained that if air traffic control regulations are not adjusted in advance or temporary no-fly zones are not established, future wind turbine assembly will face dual pressures of time and cost, and may even force developers to choose alternative ports, thereby affecting the optimization of the overall layout.

From the perspective of the industrial chain, floating offshore wind power involves not only wind turbine manufacturing and offshore installation, but also port logistics, vessel leasing, and maintenance services. If port infrastructure can be upgraded simultaneously, it will drive the technological upgrading of related domestic industries and create employment opportunities, forming a complete supply chain ranging from design and manufacturing to transportation. Conversely, if port planning lags behind, it could cause domestic enterprises to lose their competitive advantage in the international offshore wind power market, forcing them to rely on foreign contractors and weakening the growth momentum of the domestic industry. Therefore, the government needs to make advance preparations in budget allocation, land acquisition, and environmental impact assessment procedures to ensure that port expansion and air traffic control adjustments can be completed simultaneously.

In conclusion, the success or failure of the floating offshore wind power demonstration project depends not only on the wind turbine technology itself, but largely on the overall coordination of infrastructure such as ports and aviation. Only through multi-faceted, simultaneous planning of port space, deep-water berths, lifting equipment, and air traffic control policies can the grid-connection targets between 2025 and 2032 be met on schedule, providing reliable support for Taiwan's energy structure transition.
