Siemens Energy Transformers for China’s First 66 kV Offshore Wind Farm

Siemens Energy will install 22 units of distribution transformers at Yuhuan Offshore Wind Power Project Phase 1, China’s first commercial 66 kilovolts (kV) offshore wind farm.

The fluid immersed transformers of type FITformer WIND will support China Huadian Corporation (CHD) to optimize energy supply in the Yangtze River Delta region.

The first phase of the Yuhuan Offshore Wind Power Project is scheduled to be completed by the end of 2021.

Located in Taizhou, Zhejiang Province, southeastern China, the 300 MW wind farm will supply power to about 240,000 households per year once commissioned.

”To successfully drive the energy transition, it is essential to increase the share of renewables in the energy mix. Equipped with innovative state-of-the-art transformer technology, China’s first 66 kV offshore wind farm will lead the way to a significant increase of clean, renewable wind energy to the grid and will contribute to China’s goal of carbon neutrality by 2060,” said Beatrix Natter, Executive Vice President Transmission at Siemens Energy.

The FITformer WIND transformer was developed to provide the turbines with larger power capacities with a voltage class of up to 72.5 kV.

The transformers for Phase 1 of the Yuhuan Offshore Wind Power Project will be installed in the tower base of the wind turbines.

To date, more than 2,500 units of the ester fluid immersed FITformer WIND were installed in wind offshore applications worldwide, Siemens Energy said.
