Swedish utility Vattenfall today is set to kick off construction of the 403MW Horns Rev 3 offshore array off Denmark’s North Sea coast with the installation of the first of 49 monopile foundations. "Horns Rev 3 is the first of three offshore farms that Vattenfall will construct in Denmark in the coming years. These wind farms will, in the highest degree, contribute to our strategy to have a fossil free energy production within one generation," says Gunnar Groebler, head of Vattenfall's wind business.
