DONG Energy has decided to construct the 660MW Walney Extension Offshore Wind Farm, located in the Irish Sea, approximately 19 kilometres off the west coast of Britain.
The final investment decision has been made after securing all necessary consents from authorities, completing site assessments and having signed the majority of the contracts for supply and installation to build the project. Walney Extension is expected to be fully commissioned in 2018, at which time it will be the biggest offshore wind farm in the world, surpassing the 630MW London Array Offshore Wind. The wind farm will be constructed and operated under the UK's EMR FID-enabling regime with a fixed price for the first 15 years of production. DONG Energy has decided to apply two different turbines: 40 8MW turbines from MHI Vestas Offshore Wind and 47 Siemens 7MW offshore turbines.
