Engineering conglomerate JFE will build Japan’s first offshore wind foundation plant, in a boost to the nation’s plans to build a local supply base for its coming build-out of turbines at sea.

Tokyo-based JFE said it will produce monopiles and transition pieces at a plant in Kasaoka City, Okayama Prefecture, with plans later to add capabilities for jacket structures to give it “a full lineup system for offshore wind power foundation manufacturing”.

JFE expects to spend 40bn yen ($362m) on the plant and a secondary site for finishing transition pieces.
