Substation start date announced for Neart na Gaoithe

Substation installation is due to start at the Neart na Gaoithe (NnG) offshore wind farm, located 15km off the Fife coast, and under development by EDF Renewables and ESB.

Installation of the two offshore substation (OSS) jackets is due to begin from 12th May 2022, at the earliest. It is anticipated that the installation works will be completed by end-May 2022. This will be followed by installation of the South OSS topside. OSS commissioning is due to begin early June and will continue throughout Summer 2022. The offshore substation jackets are installed by the vessel Sleipnir. The South OSS topside will be brought to site using a barge, Wagenborg 7, assisted by two tugs; Pacific Discovery and Multratug 3. The North OSS topside is to be installed at a later date.

The supply of the onshore substation and the two offshore substations, plus electrical design work, was awarded to GE Renewable Energy’s Grid Solutions together with its consortium partner HSM BV.Each topside measures 35x25.5x15 metres and weighs 1200 tonnes.

Saipem’s vessel Saipem 3000 has also installed pin piles for the turbine jacket foundations at 21 locations.
The wind farms will feature 54 SG 8.0-167 DD turbines.

Once fully operational, the project is expected to generate electricity for around 375,000 homes, or all domestic properties in a city the size of Edinburgh, and to displace 400,000 tons of CO2 annually. LCCC awarded it a CfD in February 2015, with a strike price of £114.39/MWh. The first commercial supply of electricity is expected by 2023.
