Walney Extension offshore wind farm is located approx. 15km west of Barrow-in-Furness in Cumbria, off the North-West coast of England.
It is the world's largest offshore wind farm, consisting of 207 turbines installed in two phases, Walney I and Walney II. It delivers 659MW, enough to power up more than 590,000 homes in the UK.
The decommissioning provisions in the Energy Act 2004 require that a person who constructs and operates a renewable energy installation should be responsible for ensuring that the installation is decommissioned at the end of its useful life, and should be responsible for meeting the costs of decommissioning.
