General Electric Renewable Energy is evaluating its global wind supply chain in the light of US trade tariffs, which some estimates say could raise the levelised cost of energy at a new US wind farm by as much as 10% at a time when the industry is under intense price pressure.

“It’s really both the tariffs on steel as well as imports from China that are going to be the challenge for all of us – I think it’s true for everyone in the industry,” Anne McEntee, chief executive for digital services at GE-RE, said this week at a conference hosted by the American Wind Energy Association in New York.
