First turbine installed at DONG Energy’s 659MW Walney Extension offshore windfarm


Installation of the first of 40 V164-8.0MW turbines has been completed at DONG Energy’s 659MW Walney Extension offshore windfarm situated in the Irish Sea.

Carried out by MHI Vestas Offshore Wind, power being generated by the farm has been transmitted to the national grid.

The Walney Extension will be equipped with a total of 87 turbines. Siemens Gamesa will provide 47 of these, while the remaining will be supplied by MHI Vestas Offshore Wind.

"Siemens Gamesa will provide 47 of these [the turbines], while the remaining will be supplied by MHI Vestas Offshore Wind."

Once fully operational, the windfarm will be able to generate sufficient clean energy to meet the annual electricity demands of more than half a million homes in the UK.

DONG Energy's Walney Extension programme director Andrew Cotterell said: “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.”
