Greater Changhua 1 and 2a offshore wind farms form part of a series of wind farms currently under construction by Ørsted in Taiwan. Greater Changhua 1 and 2a were inaugurated in April 2024 marking two years since first power was delivered from the farm. It now operationally forms part of the largest wind farm in the Asia-Pacific region.
First Power Delivered
Reported April 22, 2022 – Ørsted successfully delivers first power from the 900 MW Greater Changhua 1 & 2a wind farms. According to Ørsted, the first power was delivered on time with the installation and activation of the first batch of offshore wind turbines transferred from the Port of Taichung to the site.
“This is a significant milestone for Ørsted and the industry because Greater Changhua 1 & 2a is Taiwan’s largest offshore wind project. It is also the company’s first large-scale offshore wind farm in the Asia-Pacific area,” the company stated.
The first turbine was deployed at the site by Seajack Scylla at the beginning of the April 2022. Seajack is a wind turbine installation vessel by Seajacks. Onshore substations received the electricity via array cables, offshore substations, and export cables. According to the corporation, renewable energy is supplied to the national grid via Taipower’s substation.
More on the Greater Changhua 1 and 2a
The 900 MW wind farms are situated 35 to 50 kilometers off the coast of Changhua County. They consist of 111 Siemens Gamesa 8 MW wind turbines.
The 605 MW Greater Changhua 1 wind farm is jointly owned. This is by Ørsted (50%) and a consortium of Caisse de dépôt et placement du Québec (CDPQ) and Cathay PE. Ørsted is the sole owner of the 295 MW Changhua 2a. It is also in-charge of developing the wind farms.
Construction at Greater Changhua wind farm
The commissioning team first used the substation and export cable of the Greater Changhua 2a a month prior to first power transmission. More testing at the two substations took place in February and December 2021.
Now with official commercial operations ongoing, operations and maintenance (O&M) team works to ensure optimal performance of the wind farm. Greater Changhua 1 and 2a will generate stable and clean energy for over 25 years.
