Greater Changhua 1 & 2a Offshore Wind Farms switch on 900 MW onshore substations for supplying stable clean energy in Taiwan

Global offshore wind leader Ørsted today (3) held a virtual ceremony, celebrating the successful and timely energization of the 900 MW onshore substations for the Greater Changhua 1 & 2a Offshore Wind Farms. Following the first power in late April, the OnSS marks the completion of the onshore construction and plays a crucial role to ensure stable transmission of clean energy to the national grid.

The energization of two onshore substations, located in Changhua Coastal  Park, Tawian, was delivered in close collaboration between Ørsted and Star Energy Corporation (SEC), a 100% subsidiary of Taiwan Cogeneration Corporation. The project has been delivered to the highest international offshore wind standards of quality, health, safety and environment (QHSE).

Christy Wang, General Manager of Ørsted in Taiwan, says: “For the past three years, our teams have worked closely with Star Energy and over a dozen of local subcontractors, to turn an area of desolate land into Taiwan’s first offshore wind transmission hub meeting international offshore wind QHSE standards. This is a great achievement for both our teams, Star Energy as well as the domestic sub-suppliers and contractors. It is also a testament to the successful combination of global offshore wind expertise and local experience.” 

“Moreover, the project serves as an excellent example of Ørsted’s efforts and dedication to cultivate a local supply chain. We are proud to see more than 80% of the Ørsted team and local contractors are from Taiwan, comprising around 1,000 people directly and indirectly involved in this project. The Greater Changhua 1 & 2a Offshore Wind Farms, the largest of its kind in Taiwan, have contributed to the development of a truly local supply chain and creating local jobs, as well as further strengthening Changhua as the green energy hub in Taiwan.”

With an investment of NTD 7 billion, this engineering, procurement and construction contract (EPC) scope includes two state-of-the-art substations and a 3.7-kilometer culvert box that allows ventilation and protection of the cables. Throughout the project construction, Ørsted has demonstrated a steadfast commitment to safety as a remarkable record of 1.7 million hours without a recordable incident has been achieved for the entire onshore substation project. 

Tsai Chin-Fa, Chairman of Star Energy, says: “The collaboration with Ørsted on the onshore substation and onshore transmission system was Star Energy’s first foray into the offshore industry, which was a critical decision to transform ourselves from inside out. Not only have we changed our mindset on QHSE, most importantly, we have also created partnerships with many local small and medium-sized enterprises, encouraging them to be part of Taiwan’s green energy transformation journey.”

Taiwanese suppliers participated in various scope of the EPC contract, from civil engineering, reactors, cable laying, equipment installation all the way to provision of air conditioning equipment. 

As Taiwan’s most reliable green energy partner, Ørsted will continue working with local suppliers and contractors to deliver world-class offshore wind farms, contributing to stable green energy transition in Taiwan.
