Danish offshore wind farm developer Ørsted has delivered the first power from Taiwan’s largest offshore wind project, a development that marks another milestone in the company’s offshore wind power ambitions.

Ørsted announced it has successfully delivered first power from the Greater Changhua 1 & 2a offshore wind farm, Taiwan’s largest offshore wind project and the company’s first large-scale project in the Asia-Pacific region.

Located 35-60 kilometers off Taiwan’s west coast, the wind farm has a total capacity of 900 MW. Once completed this year, the wind farm will significantly support Taiwan’s fast-track build-out of renewables.

Taiwan’s authorities have put top priority on the development of renewable energy, with offshore wind power expected to contribute significantly to the goal of generating 20 percent of the nation's electricity with renewables by 2025.

“Delivering the first power as scheduled is a major milestone for both Ørsted and Taiwan. Since the 900 MW capacity was first awarded to Ørsted in April 2018 through the grid allocation process, our team has spared no efforts to develop and construct Greater Changhua 1 & 2a and achieve first power only four years later,” said Christy Wang, Ørsted Taiwan General Manager.

A total of 111 Siemens Gamesa 8.0-167 DD wind turbines will be installed at Changhua 1 & 2a, which will produce enough power to cover the power consumption of a million Taiwanese households.

“Managing the risks of the key component fabrication, vessel mobilization and installation of the offshore wind farm has been imperative during the COVID-19 pandemic,” said Ulrik Lange, Greater Changhua 1 & 2a Offshore Wind Farm Co-CEO.

The Greater Changhua 1 wind farm is owned by Ørsted, which controls a 50 percent stake. A consortium comprising Caisse de dépôt et placement du Québec (CDPQ) and the Taiwanese private equity fund Cathay PE control the remaining 50 percent. Ørsted solely owns the 295 MW Changhua 2a.

Apart from the Greater Changhua 1 & 2a wind farm, the leading offshore wind developer is the major shareholder and co-owner of Taiwan’s first commercial-scale offshore wind project, Formosa 1, which was extended from 8 MW to 128 MW in 2019.

Ørsted was also awarded the right to build the 920 MW Greater Changhua 2b and 4 offshore wind farm and has signed a power purchase agreement with Taiwan Semiconductor Manufacturing Company Limited (TSMC). The wind farm is expected to become operational in 2025 and will be fully commissioned in 2026, subject to grid availability and Ørsted’s final investment decision.

The company also announced that it has started the environmental impact assessments of the Xu Feng 1, 2 and 3 projects off the coast of Changhua County, with a total potential capacity of 2.1 GW, and the Wo Neng 1 and 2 projects off the coast of Taichung, with a potential capacity of 3 GW.

Around the world, Ørsted has installed more than 1,600 offshore wind turbines with a combined capacity of 7.6 GW, and it has an additional 3.4 GW under construction. The company has ambitions to install a total of 30 GW of offshore wind capacity worldwide by 2030.
