Keppel O&M completed the construction of the jacket foundations for the two unmanned 600 MW offshore substations in the second quarter of 2021 and will be undertaking the integration work for the offshore substations.

The jackets were installed by Aegir in May and June.

Once operational, the Greater Changhua 1 & 2a will be Taiwan’s first far shore and large-scale offshore wind project.

Located some 35 to 50 kilometres off the coast of Changhua County, the 900 MW wind farms will comprise the two substations and 111 Siemens Gamesa 8 MW wind turbines scheduled to be fully operational by the end of 2022.
