The Walney Extension, a Danish-led and funded project in the Irish Sea off Cumbria, has 87 turbines - each around twice the height of Big Ben, standing approximately 190 metres high. The windfarm is nearly 12 miles off Walney Island, Barrow-in-Furness, and covers an area of 145 square kilometres - equal to an area of around 20,000 football pitches.
