The plant expansion allows the company to manufacture 600MW class hydro power generation equipment and to double its manufactured output.
Toshiba said that the expansion positions the company to meet growing demand for hydro power in China and the world market, most notably India and Southeast Asia.
Alongside the expansion, Toshiba Hydro has also constructed a hydro power R&D facility in China.
The company’s manufacturing operation includes casting, welding, assembly and machining and a coil shop.
