Development consent for the Outer Dowsing Offshore Wind Farm, located approximately 54 kilometres off the Lincolnshire coast, has been approved by the UK Government
Development Consent Granted for Major Offshore Wind Project
Development consent has been granted for the Outer Dowsing Offshore Wind Farm, marking a significant step forward for one of the UK’s larger planned offshore energy developments.
Approval was issued by the Secretary of State on 10 February 2026 to GTR4 Limited, a joint venture between Corio Generation, TotalEnergies and Gulf Energy Development.
The project will be located approximately 54 kilometres off the coast of Lincolnshire and is expected to become a major contributor to the UK’s offshore wind capacity.
Project Scope and Infrastructure Details Confirmed
The approved development includes plans for up to 100 wind turbine generators, alongside a substantial offshore and onshore infrastructure network.
This will comprise an offshore accommodation platform, up to six offshore transformer substations, as many as two offshore reactive compensation platforms, and up to four export cables. These cables will make landfall at Wolla Bank before continuing underground to a new substation at Surfleet Marsh.
Construction could begin as early as 2027, with first power targeted for 2030.
Contribution to UK Offshore Wind Targets
Once operational, the wind farm is expected to deliver up to 1.5 gigawatts of capacity.
This would represent a notable contribution towards the UK Government’s target of 50 gigawatts of offshore wind generation by 2030, forming part of wider efforts to meet national net zero commitments.
However, as with other large-scale offshore developments, questions remain about cumulative spatial pressures at sea, particularly in areas already used by the fishing industry.
Regulatory Oversight and Environmental Assessment
The Marine Management Organisation worked alongside the developer, the Planning Inspectorate and other stakeholders throughout the application process.
According to the MMO, this collaboration was aimed at ensuring environmental considerations were fully addressed during examination.
The project was also included in the Nationally Significant Infrastructure Project Early Adopters Programme, an initiative designed to streamline planning processes and improve issue tracking during the examination phase.
Next Phase Moves Towards Construction
Following the granting of consent, the MMO will continue to engage with the developer as the project moves into its pre-construction phase.
This stage will focus on meeting consent conditions and preparing for offshore construction, which remains subject to further regulatory approvals and detailed planning.
While the approval represents progress for offshore wind expansion, the practical implications for existing marine users and the effectiveness of mitigation measures are likely to remain under scrutiny as the project advances.
