Chinese Wind-Turbine Companies Seek Global Growth as Western Rivals Struggle

TARANTO, Italy—Chinese wind-turbine makers have grown big on the back of their rapidly growing home market. Now they want to expand abroad, putting further pressure on Western wind-turbine makers, which have been struggling to profit from a renewable-energy boom.

The ambitions are visible near this coastal city on the heel of the Italian boot, where Renexia SpA, the renewable-energy arm of Italian infrastructure company Toto Holding SpA, recently inaugurated Beleolico, a 30-megawatt offshore wind farm using Ming Yang Smart Energy Group Ltd. turbines, last month.
