Mainstream has progressed the development of the Horizont project in the North Sea since 2009 and has undertaken all necessary environmental surveys, geophysical and geo-technical investigations and has received consent and first release (technical consent) in 2013.

However, due to regulatory constraints in the German offshore wind sector, Mainstream is awaiting further confirmation of the offshore sector in Germany before continuing its development.

Milestones achieved:

o BSH Stakeholder conference held in March 2013 and successfully passed.
o Environmental, geophysical and preliminary geotechnical surveys completed.
o Foundation, installation and O&M studies on track completed.
