Greater Changhua 1&2a Onshore Substation Construction Begins

Greater Changhua 1&2a Onshore Substation Work Kicks Off

Ørsted has held a groundbreaking ceremony to mark the kick-off of the onshore substation construction for the Greater Changhua 1 & 2a offshore wind project in Taiwan.


In November 2018, Ørsted awarded an EPC contract to Taiwan Cogeneration Corporation (TCC) to build two onshore substations, cable corridors and transition joint bays for the 900MW project.

Under the contract worth more than TWD 7 billion (around EUR 200 million), Star Energy, 100% owned by TCC, is responsible for all onshore deliverables regarding design, procurement, construction and commissioning of the substations.

According to Ørsted, Star Energy has hired more than 60 additional employees since last year, and during the construction period, there will be up to 1.000 people working on the onshore substation.

Taiwan Electrical and Mechanical Engineering Services, Inc. and GIBSIN Engineers, Ltd, together with the National Taipei University, are the design consultants.

Chung-Hsin Electric and Machinery Manufacturing Corporation will supply GIS (Gas Insulated Switchgears), with Fortune Electric Corporation supplying SGT (Super Grid Transformers) to the onshore substations.

“Together with the EPC contractor SEC, Changhua 1&2a projects will implement the highest global QHSE standards at the onshore construction site and comply with EIA commitments, including sending archaeological experts to the site and controlling air pollution and noise,” said Matthias Bausenwein, President of Ørsted Asia Pacific and Chairman of Ørsted Taiwan.

“We will not only fulfill local content requirements, but also work together to enable our EPC contractor and his local suppliers to bring their QHSE practice to international standards and enhance their competences.”

The Greater Changhua 1 & 2a offshore wind farms will feature Siemens Gamesa 8MW turbines installed on jacket foundations some 35 to 50km off the coast. Offshore construction is expected to commence in 2021.
