State-controlled power group Shenhua has made the first wind investment by a Chinese company in Greece as part of a planned €3bn ($3.5bn) programme – and ahead of a mega-merger that will see it become part of the world’s biggest power group.

Shenhua bought a 75% stake in four wind projects developed by Copelouzos, a Greek infrastructure group that says it has a 3GW pipeline in the country.
