The chief executive of Toshiba said it will seek a “strong partner” as it targets a Japanese-made turbine that can compete in the country’s fast-growing offshore wind market.

Toshiba will raise its ambitions in wind as part of a push to more than triple the size of its renewable energy business by 2030, adding to its existing power technology business in solar, geothermal and hydropower, said CEO Nobuaki Kurumatani.
