Once completed in June, the EDF Energy Renewables windfarm will have a generating capacity of 62MW.
Christian Egal, chief executive of EDF Renewables, said: “This is an important milestone for us and one that will help us maintain our commitment to deliver energy in a way that is sustainable, affordable and secure.”
The completion of the Teeside offshore windfarm will increase EDF Energy Renewables’ generating capacity from 463MW to 525MW.
