In February 2015, Mainstream was awarded a Contract for Difference by the UK Government.  Under the competitive tendering process, the wind farm receives an inflation-linked strike price for the electricity it produces for a period of fifteen years.  The wind farm, which was awarded planning consent in October 2014, is expected to be generating electricity and fully commissioned by 2020.

Milestones achieved:

  • Onshore consent received from East Lothian council in June 2013.
  • Offshore consent expected 2014.
  • Secured firm grid connection for 2016.
  • Site complies with the Scottish Government’s Strategic Environmental Assessment (SEA) for offshore wind.
  • Scoping Report submitted to the Scottish Government and a Scoping Opinion received from the Scottish Government in early 2010.
  • Completed geophysical, preliminary geo-technical and met ocean campaigns.
  • Deployed floating LiDAR at the offshore wind farm site from April 2014 to April 2015.
  • Awarded CfD by National Grid in February 2015.
  • Equity consortium in place in early 2016 and includes: Siemens Project Ventures, Infrared Capital, The Marguerite Fund.

Mainstream was awarded the Neart na Gaoithe site by The Crown Estate as part of a competitive bidding process.  Mainstream’s bid was the culmination of extensive site selection, analysis and stakeholder engagement and the site was chosen because it combined technical, economic and environmental deliverability.

Neart na Gaoithe (meaning ‘Strength of the Wind’) located in the Outer Forth estuary will cover an area of approximately 100km2. The project has the potential to generate up to 450 megawatts of renewable energy, enough power to supply over 325,000 Scottish homes – more than the whole of Edinburgh. It will offset over 400,000 tonnes of CO2 emissions each year, as well as make a significant contribution towards the delivery of the UK and European renewable energy targets.
