SSE Renewables is renaming its Seagreen 2 and 3 offshore wind projects off Scotland to the Berwick Bank and Marr Bank wind farms, respectively.
Both projects are located in the North Sea beyond the Firth of Forth.
The proposed installed capacity of Berwick Bank is between 1400MW and 2300MW and Marr Bank is between 900MW and 1850MW.
Combined, the projects have potential to “significantly contribute” to Scotland’s ambitious climate change targets.
Berwick Bank could be operational as soon as 2027 with Marr Bank following slightly later timescales.
Berwick Bank wind farm has secured a grid connection at Branxton, near Torness, in East Lothian.
SSE Renewables said the reason for renaming the two projects is to distinguish them from neighbouring project, Seagreen 1.
All three sites were awarded exclusive development rights by the Crown Estate in 2010 but are now progressing on separate tracks, with Seagreen 1 having reached a final investment decision in June 2020.
The new names are a “nod” to the geological history of each site, said SSE Renewables, including the remains of the last glacial maximum, over 20,000 years ago.
During this time, widespread movement of glaciers in the entire North Sea and, in particular, the area off the Firth of Forth, resulted in a thick layer of sediment being deposited.
The sediment is historical evidence of the environmental change in the area.
SSE Renewables lead project manager Malcolm Grant said: “Offshore wind is critical if both Scotland and the UK are to achieve net zero.
“The two wind farms will contribute significantly to carbon reduction targets and will help to drive forward a green recovery. We’re pleased to have renamed them to help distinguish them as separate sites in their own right.”
Berwick Bank sits 54km off the Angus coast at its closest point and Marr Bank sits over 43km off the coast.
