Scotland hailed a major milestone in its energy transition on Tuesday when its largest offshore wind project so far – the 1.1GW Seagreen – exported power from the first of its 10MW Vestas turbines.

The £3bn ($3.5bn) Seagreen, which is being developed by oil group Total Energies and UK utility SSE, is set to be fully operational by the halfway point of 2023 when it will produce enough power for 1.6 million households, said the partners.

TotalEnergies in 2021 bought a 51% share in Seagreen in a deal that marked the French supermajor’s first large-scale foray into offshore wind.
