The Board expects to elect the company's former CEO, Anders Runevad as the new chair after Vestas' annual general meeting on April 12, the company said.

"Now that the path back to profitability has been re-established and the right successor is in place, I have decided to dedicate more time to other things, including my family," Nordberg said in a statement.

Nordberg has been Vestas chair since 2012.
