Now that MHI Vestas Offshore Wind has installed the first of 40 V164-8.0MW turbines, power is now being exported to the national grid. This is an important milestone for the 659MW project which will supply the national grid.

A further 47 Siemens Gamesa turbines will complete the 87-turbine wind farm, which will have the potential to enough clean energy to meet the annual electricity demands of more than half a million UK homes.

Once fully commissioned, Walney Extension will leapfrog London Array to become the world’s largest operational offshore wind farm, says DONG Energy.

Construction of the project is being organised from a base at the Port of Barrow, which also includes the operation and maintenance teams for three other firm’s energy offshore wind farms such as Barrow, Walney and West of Duddon Sands.

Record-breaking project

Walney Extension, which covers an area of up to 149km², includes wind turbines, foundations, inter array cables, offshore and onshore export cables within an export cable corridor and offshore and onshore substations that will connect the project to the National Grid.

The project takes its name from its location, situated  around 19km southwest from the Isle of Walney in Cumbria off England’s northwest coast..

Andrew Cotterell, Walney Extension’s programme director at DONG Energy, says, “Exporting first power to the grid on schedule is the culmination of extensive onshore and offshore works and is testament to the hard work of everyone involved. In general, construction is progressing well to bring this record-breaking project online.”
