The most momentous milestone yet in the development of the Neart na Gaoithe (NnG) offshore wind farm has been reached with the installation of its first wind turbine at sea.

The turbine, with a tip height of over 200 metres was installed by Siemens Gamesa from the specialist jack-up wind turbine construction vessel, the Blue Tern, which initially placed the 87.5 metre turbine tower on its pre-installed steel jacket. This was followed by the installation of the 350 tonne nacelle, containing the turbine generator, on top of the tower. Finally, its three blades, each 81 metres in length, were bolted to the nacelle.

Once commissioned, this will be the first NnG wind turbine to generate clean, green electricity for the National Grid. Its 8MW of power will be sent via the subsea inter-array cable to its offshore substation then onwards to shore via the subsea export cable to Thorntonloch Beach, where the underground onshore export cable will transmit its power to the national grid.

The turbine’s journey to site began in the Port of Dundee when its component parts were loaded, alongside those of three further turbines, onto the Blue Tern.

NnG, which is owned by EDF Renewables UK and ESB, will ultimately supply enough low carbon electricity for around 375,000* homes and has a capacity of around 450MW of low carbon energy. It will offset over 400,000 tonnes of CO₂ emissions each year. The project will be fully operational in 2024.
