The judgement call

Account-gated at launch

The project successfully delivered first electricity ahead of full completion, demonstrating efficient project phasing. - The use of an OFTO model for transmission assets highlights a common approach for financing and operating offshore wind infrastructure.

Key engineering challenges

Geotechnical analysis and engineering to ensure no pile refusal during foundation installation. - Integration of the wind farm into the UK's national grid via an OFTO (Offshore Transmission Owner) system. - Managing the construction and operation in a busy offshore environment.
