“ 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.
*SEEC = Shiling Electric & Engineering Corporation
