In May 2018, Mainstream sold the Neart na Gaoithe offshore wind farm project to EDF Renewables. This was always the long-term plan for the project and EDF will bring the project through construction and into commercial operation.  See press statement here.

The 450MW Neart na Gaoithe (NnG) offshore wind farm project is located off the east coast of Scotland. Mainstream Renewable Power has been developing this project since 2008.  It was awarded the development rights for the site from The Crown Estate (TCE) in February 2009.  Visit the project website here.

This £2bn project is capable of supplying all the homes in a city the size of Edinburgh with clean energy. It will create around 2,000 Scottish jobs for every year of construction and around 236 Scottish jobs for each year during the lifetime of the project – 25 years.  NnG’s impact on Scottish GDP (in 2016 terms) is equivalent to 0.6% of the country’s onshore GDP, or £827m over the lifetime of the project.

In August 2017, the NnG Offshore Wind Coalition was launched and has doubled in size since then to some 78 supply chain companies highlighting the economic benefits of the project.  Learn more about the Coalition here.

Timeline to commercial operation
The Neart na Gaoithe offshore wind farm will be built out in a number of stages. Construction of onshore works will commence in 2019 at the earliest while offshore works will commence in 2020 at the earliest.

Contract for Difference
In February 2015 the project was awarded a Contract for Difference (CfD) by the Low Carbon Contracts Company. The CfD, which was awarded under a highly competitive tendering process, gives the wind farm an inflation-linked strike price for the electricity it produces for a period of fifteen years. NnG was one of only two offshore wind farms to succeed and win a CfD contract through this auction process in early 2015.

Supply Chain
Mainstream is in the process of selecting Tier 1 supply chain partners with proven track records of innovation and execution, to deliver NnG using best available engineering techniques.

Mainstream is a highly innovative, independent developer of offshore wind and is responsible for showcasing a number of disruptive technologies, such as the twisted jacket foundation and the floating lidar (FLiDAR) pictured right.

Project facts
Neart na Gaoithe means “Strength of the Wind”.

  • When fully operational, it will generate enough electricity to power over 325,000 households. This is equivalent to the domestic electricity needs of its closest city, Edinburgh.
  • The closest turbine will be 15.8 kilometres from the shore.
