Originally, Seagreen was to be developed as two projects Alpha and Bravo, however these were later combined as the Seagreen 1 project. The adjacent projects, Seagreen 2 and 3 were renamed as Berwick Bank and Marr Bank, then combined under the name
Berwick Bank. In October 2014, the
Scottish Government granted planning consent for the offshore works. This was reversed in May 2017 following appeal by the Scottish Government. In November 2017, RSPB Scotland was refused permission to appeal this decision in the Supreme Court. In 2018, a revised application was submitted to use fewer but larger wind turbines. In 2020, planning consent was awarded for the onshore connection, for the Tealing Substation in January, and for the cable route in June. In December 2021, the installation of the turbines started, with the final turbine installed in June 2023.
