Located 35 to 60 kilometers off the coast of Changhua County, Greater Changhua 1 and 2a are Taiwan’s largest far-shore offshore wind farms in operation. Compared to near-shore projects, far-shore wind farms require a more comprehensive operations set-up, including vessel logistics, workforce planning, and asset condition monitoring with 24/7 on-call support functions.
Over the past two years, the wind farms have maintained stable performance through several typhoons and multiple earthquakes of magnitude above 5, demonstrating resilient power generation. Supported by Ørsted’s Taiwan-based operations and maintenance (O&M) team and stringent safety practices, the wind farms continue to deliver reliable output, with a capacity factor well above the global average offshore wind performance of 42 %1 (International Renewable Energy Agency, IRENA), highlighting the strong and consistent performance of far-shore offshore wind generation.
Christy Wang, Chair of Ørsted Taiwan, says: “Stable offshore wind generation depends on strong local capabilities supported by global back-office excellence. Our operations set-up is enabled by a skilled team of nearly 100 people based in Taiwan and a domestic supply chain of more than 20 companies. I’d like to thank our colleagues and suppliers for their dedication and professionalism in delivering strong performance under Taiwan’s unique and complex weather and sea conditions.”
Andreas Munk-Janson, Head of Ørsted Generation APAC, says: “Reliable offshore wind comes down to how we operate every day, with safety at the core of everything we do. Through proactive safety leadership, we’ve built a strong track record with a low incident rate across both onshore and offshore operations, supported by disciplined processes and data-driven insights.”
Ørsted continues to adapt its operations to Taiwan’s distinct environmental conditions, including high temperatures and humidity, which place additional demands on offshore work compared to other global regions. To manage heat-related risks, Ørsted implements targeted safety measures such as adjusted work-rest cycles, enhanced airflow solutions, and cooling equipment. These are complemented by regular emergency response drills and broader safety programmes across all teams to ensure safe and reliable operations.
Ørsted’s Generation business draws on more than 35 years of experience across 30 global offshore wind farms, with data-driven asset performance in focus, applying advanced data analytics and predictive system maintenance tools. These capabilities enable early identification of potential failure modes during daily operations. Globally, up to 70 % of certain component failures at Ørsted’s offshore wind farms can be predicted months in advance, reducing the unplanned asset downtime and thereby maintaining high availability.
Ørsted’s build-to-operate model integrates O&M requirements from the early stages of wind farm design; for the Greater Changhua 1 and 2a offshore wind farms, this work started back in 2018.
Today, Ørsted’s Taiwan-based team operates from the ‘TSS Pioneer’, a purpose-built service operation vessel (SOV), specifically designed for the Greater Changhua offshore wind farms and the unique and challenging sea conditions in the Taiwan Strait. Together with the largest offshore wind operations hub in Asia Pacific located at Taichung Port and with dedicated office, warehouse, and operational facilities, the current set-up supports a total operational capacity of 1.82 GW, including the 920 MW Greater Changhua 2b and 4 offshore wind farms, while also providing scalability to support Ørsted ‘s growing offshore wind portfolio in Taiwan.
With Taiwan’s only proven track record in building and operating far-shore offshore wind farms, Ørsted continues to strengthen its engineering, O&M, and local talent capabilities. The local team currently includes more than 50 O&M technicians and continues to grow in both scale and expertise. Through the stable and long-term delivery of large-scale renewable power, Ørsted is committed to supporting Taiwan in strengthening its energy resilience and independence, while contributing to the country’s energy transition and sustainable industrial development.
