Challenge  
ScottishPower Renewables and Vattenfall Wind Power began working on an equal collaborative partnership in 2009 to develop capacity for offshore wind generation off the East Anglian (UK) coast. East Anglia ONE, with a capacity of 714MW, was the first project to be selected for development within the East Anglia zone. The project achieved consent in 2014 and was awarded a Contract for Difference by the UK Government in 2015 with the lowest levelised cost of energy. In February 2015, ScottishPower Renewables became the sole developer on East Anglia One.

Building a project of this scale requires a wide variety of technical competencies. DNV GL was ScottishPower Renewables engineering partner on the project, providing a wide range of technical services throughout the development of the wind farm.
