Our history

A history of milestones

Seagreen has been a decade in the making during which time we've celebrated many project milestones.  Although some were perhaps smaller than others, each was important as we brought Seagreen through the development and construction phases resulting in Scotland's largest offshore wind farm which became operational in October 2023.

Some of our favourite milestone's are listed below and many link to the associated news stories:
