Formosa 2 completes all jacket foundations and Subsea Cables, more than half of the turbines installed
Taipei, September 1st, 2022 -Formosa 2 offshore wind project is pleased to announce hitting multiple construction milestones to date, including the completion of all 47 wind turbine foundations and subsea cable installation works. The final jacket foundation was installed on 26th August, with the subsea cable works reaching installation completion 6 days later on 1st September.
Since the last construction updates announced in July, Formosa 2 project team has kept making steady progress with all the available weather windows utilised. Currently Formosa 2 has completed 27th wind turbine installation, which is more than half of the total turbines. Among them, 8 wind turbines have started generating power to the national grid.
The turbine foundations of Formosa 2 were designed and constructed specifically to suit prevailing Formosa2 site geological and met-ocean conditions off the coast of Taiwan, also taking account also of seismic conditions. The jacket foundation structures are amongst the tallest constructed to-date world-wide at up to 91m in height and weighing up to 1,581 tons. The 47 structures were installed on the offshore site between April and 26th August 2022.
The pin piles, which the jacket foundations are installed upon, are approximately 2.4m diameter, up to 277 tons in weight and some 78.9m in length. The installation of the 188 pin piles was concluded earlier in August 2022. The wind turbine foundations are connected by 47 sections of Inter Array Cables with a further four export cables transmitting the power to the onshore electricity grid. The combined total length of installed subsea cables is 114km with all subsea cables rated at 69kV.
Formosa 2 has been dedicated to bringing benefits to the local supply chain and supporting jobs in the offshore wind industry from the very beginning. In addition to its collaboration with the National United University in Miaoli, Formosa 2 has also held an art competition to expand green energy education to local middle and elementary schools, laying a solid foundation for future green talent.
When complete, the project will have an installed capacity of 376 MW and will supply power to approximately 380,000 households. It is being developed by JERA, Macquarie’s Green Investment Group (GIG) and Swancor Renewable Energy (SRE). GIG is supported by its portfolio company, Corio Generation.
