Ørsted has completed the installation of all 66 Siemens Gamesa SG 14-236 wind turbines at the Greater Changhua 2b and 4 offshore wind projects in Taiwan, marking a significant milestone in the region’s renewable energy expansion. Located 35–60km off the coast of Changhua County, the 920MW project has been supplying electricity to Taiwan’s grid since achieving first power in July 2025.
The project, which commenced offshore construction in February 2025, is notable for being the first in the region to deliver renewable power to Ørsted’s corporate customer under a power purchase agreement signed in 2020. The installation campaign, which began in April 2025 using Cadeler’s Wind Maker vessel, concluded in just 275 days, showcasing Ørsted’s disciplined execution and rigorous risk management.
Safety was a priority throughout the project, with around 131,576 working hours offshore recorded with zero lost-time injuries. The project also achieved several technical firsts, including the first regional deployment of piling-free suction bucket jacket foundations and the global use of 14MW turbines with 115m-long blades.
Per Mejnert Kristensen, CEO of Ørsted Region APAC, highlighted the significance of the milestone, stating, “With all wind turbines now installed, we have achieved an important milestone in Taiwan’s offshore wind expansion and Ørsted’s 8.1GW historically large construction pipeline.”
Jayaram Naidu, Managing Director of Ørsted Greater Changhua offshore wind farms, emphasized the challenges overcome, noting, “Completing the offshore wind turbine installation for a 920MW project within a single installation season is a significant achievement, particularly given the short weather window and challenging sea conditions in the Taiwan Strait.”
The focus will now shift to commissioning, electrical system testing, and completing cable works, with full commercial operation expected in the third quarter of 2026 (Q3 2026).
This development underscores the growing momentum in Taiwan’s offshore wind sector and sets a precedent for future projects in the region. The successful completion of the Greater Changhua project could accelerate Taiwan’s transition to renewable energy, potentially influencing policy and investment decisions in the sector. Moreover, the project’s technical innovations and safety record may serve as a benchmark for other offshore wind developments globally.
