Formosa 1 Offshore Wind Farm has two phases of development

Phase 1

being solely completed by Swancor Renewable Energy. Despite the doubts of the public toward offshore wind, the lack of domestic supply chain, regulations and infrastructure in Taiwan, such as the heavy cargo wharf, Formosa 1 imported technical team and construction vessels from Europe, integrating the offshore engineering and sub-sea cable installation team in Taiwan and completed the “mission impossible”, the installation of two demonstration turbines of 8MW capacity, in Octobar 2016 with two typhoons hitting Taiwan during the process. With this, Swancor Renewable Energy set a milestone in the history, sounded the horn of and lit up a bright future of the offshore wind industry in Taiwan.

Phase 2

Formosa 1 experienced a major upgrade of the shareholder structure. Ørsted and Macquarie Capital joined at the early stage of Phase 2 and provided manpower of technical, financial and construction expertises for forming Taiwan’s first international team for offshore wind and installed 20 more wind turbines with the capacity of 120MW together. The team successfully delievered Formosa 1 Offshore Wind Farm in Octobar 2019.

Formosa 1, being the first commercial-scale offshore wind farm in the Asia-Pacific region, achieved a record of zero industrial accident during the four million working hours of installaion. The development of Formsoa 1 also serves as an examination into Taiwan’s regulation and infrastructure of offshore wind farm. The power generated by Formosa 1 Offshore Wind Farm is sufficient to supply the electricity usage of 128,000 households per year with a reduction in CO2 emission by 245,000 tonnes. Formosa 1 has contributed to the sustainable development of the environment of Taiwan.
