“ As offshore wind comes to Taiwan, so too does top-of-the-

line technology transfer,” said Maida Zahirovic, MHI Vestas

Taiwan Business Director. “High voltage transformers are

vital to ensuring that maximum electricity output reaches end

consumers in Taiwan.

The collaboration between Hitachi ABB Power Grids and

SEEC means that world-class production is being set up

locally for a critical component in the certified V174 platform.”

• Hitachi ABB Power Grids & SEEC* formed a partnership end

of 2019 for localizing the WindSTAR with key components

manufactured in Taiwan.

• Technology transfer is in progress and SEEC is upgrading

some machines to be able to manufacture the WindSTAR

high performance & compact core winding.

• Changfang and Xidao will be the first projects where the

localized transformers will be used.
