Work to install the cables that will carry electricity from RWE npower renewables' Gwynt y Môr Offshore Wind Farm off the North Wales coast has been completed.
The final sub-sea cable burial was completed between the coast and one of the two offshore substations last week.
Four cables have been buried in the seabed between the offshore platforms, more than ten miles offshore, and the beach at Pensarn.
They will carry the electricity generated by the wind turbines to shore, with our onshore underground cable route delivering the power on to a new substation near St Asaph Business Park.
Gwynt y Môr project director Toby Edmonds said: "Installation activity at the offshore site has been going well in recent weeks and the completion of export cable burial is an important stage in the construction of the wind farm."
Work on the export cable has been carried out by Prysmian PowerLink Services, based in Essex, using their barge, Cable Enterprise.
At 576MW, Gwynt y Môr is one of the largest offshore wind farms currently in construction in Europe.
It is a shared investment between partners RWE Innogy, Stadtwerke München GmbH and Siemens.
Once fully operational, energy generation from Gwynt y Môr is expected to be equivalent to the average annual needs of around 400,000 homes.
