About
Background
In early 2021, the Outer Dowsing Offshore Wind project was successful in securing Preferred Bidder status for a 1.5GW offshore windfarm in the Southern North Sea as part of the UK’s Offshore Wind Leasing Round 4.
Together, the six Round 4 projects awarded under the Round 4 leasing process, represent just under 8 GW of potential new offshore wind capacity with the opportunity to deliver clean electricity for more than seven million homes and create employment opportunities across the country.
Known as Outer Dowsing Offshore Wind, the site was chosen through a competitive seabed tender process.
It will now progress to environmental assessment known as a Plan-Level Habitats Regulations Assessment (HRA), assessing the potential impacts of the Round 4 plan on the UK national network of protected areas, covering its most valuable species and habitats.
Expected to conclude during 2022, after which the Crown Estate will then award the seabed Agreement for Lease.
The Project
Outer Dowsing Offshore Wind is a 1.5GW project located approximately 54km off the Lincolnshire coast.
The project is being developed by Corio Generation (a wholly-owned Green Investment Group portfolio company) and TotalEnergies, and will be one of the UK’s largest offshore wind farms upon completion. It is anticipated to generate renewable electricity equivalent to the annual electricity consumption of over 1.6 million households and will play a critical role in achieving the UK Government’s ambition to deliver 50 GW of offshore wind by 2030 and achieve net zero by 2050.
Outer Dowsing will displace the equivalent of nearly 2 million tonnes CO2 emissions per year of operations through the generation of renewable electricity. This is also the equivalent of removing over 650,000 petrol cars from the road for the duration of the Project.

Project Milestones
The UK Government has ambitious plans to have 50 GW of operating offshore wind capacity installed by 2030 – enough to potentially power every home in the UK.
Innovation and economies of scale within the offshore wind industry have helped to significantly drive down costs whilst at the same time decarbonising the economy and generating thousands of jobs in the supply chain. The sector has supported the regeneration of a number of local coastal communities and economies through both the construction and ongoing maintenance of projects.
The new British Energy Security Strategy is now expected to further increase the number of renewables industry opportunities in the UK by supporting 90,000 jobs in offshore wind by 2028 whilst at the same time reducing our reliance on imported fossil fuels.
Outer Dowsing Offshore Wind will be one of the UK’s largest offshore wind farms upon completion. It is anticipated to generate renewable electricity equivalent to the annual electricity consumption of over 1.6 million households and will play a critical role in achieving the UK Government’s ambition to deliver 50 GW of offshore wind by 2030 and achieve net zero by 2050.
The following milestones are planned to be achieved by 2030:
- Round 4 ‘Preferred Bidder’ status awarded (achieved)
- Publication of Scoping Report
- Submission of the Preliminary Environmental Information Report
- Submission of Development Consent Application
- Development consent granted
- Project commissioned and contributing to UK Government’s 2030 offshore wind targets
FAQs
Climate Change and Energy
Offshore wind farms are considered more reliable than onshore wind farms, as a result of higher wind speed and greater wind consistency. Outer Dowsing Offshore Wind will be part of a network of other offshore wind farms, low carbon power stations, interconnectors and energy storage facilities supporting British electricity supply which, together, given their diverse locations and different operating characteristics will provide energy that can be balanced and transmitted where needed by National Grid.
Increasing the amount of offshore wind we generate domestically will reduce Britain’s reliance on energy imports and foreign markets, increasing energy security and reducing exposure to fluctating energy prices. By producing electricity within the UK from renewable sources such as offshore wind there is the opportunity to decouple UK electricity prices from the volatility of internationally-traded markets for fossil fuels.
Once operational, Outer Dowsing Offshore Wind will generate renewable electricity equivalent to the annual electricity consumption of over 1.6 million households and will play a critical role in achieving the UK Government’s ambition to deliver 50 GW of offshore wind by 2030 and achieve net zero by 2050. Outer Dowsing will displace the equivalent of nearly 2 million tonnes CO2 emissions per year of operations through the generation of renewable electricity. This is also the equivalent of removing over 650,000 petrol cars from the road for the duration of the Project.
Outer Dowsing Offshore Wind is an electricity generator and not a retailer or provider. The electricity generated by ODOW will be transmitted directly into the National Grid 400kv network.
Following years of development and improvement, offshore wind is now one of the cheapest forms of electricity generation in the UK. ODOW expects to sell its power through the UK Government’s Contracts for Difference (CfD) scheme, a competitive arrangement that fixes the price ODOW will receive for its power. A competitive auction keeps prices low for consumers, whilst a guaranteed price provides predictability for customers and helps reduce the cost of financing for ODOW, keeping downward pressure on prices. The latest CfD auction, held in July 2022, secured the largest ever amount of home-grown, cheap renewable energy for British consumers at record low prices. The cost of electricity from offshore wind projects in this auction was just £37.35 per megawatt hour (MWh) – the lowest cost of all renewable technologies, and significantly cheaper than the prevailing cost of wholesale electricity at that time, which was trading at over £150/MWh for much of 2022 (Source RenewableUK).
Construction and Design
It is currently anticipated that construction will take up to 36 months
The Offshore Transmission Network Review (OTNR) is a review launched by the Department of Business, Energy & Industrial Strategy (BEIS) in September 2021 which looked into the way that the offshore transmission network is designed and delivered to achieve the national goal for net zero emissions by 2050. The draft recommendations consider a number of different connection options will be taken forward for further analysis taking into account the most appropriate balance between environmental, social and consumer costs. Outer Dowsing Offshore Wind is therefore progressing with developing cable route and substation site options for Lincs Node and Weston Marsh until the connection location is confirmed by National Grid in early 2023.
No new overhead lines will be built as part of the project; all power generated by the project will be transmitted by underground (or submarine) cables to the National Grid substation. Any new overhead lines that may be required as part of wider reinforcements of the transmission system will be responsibility of National Grid. Any such works will have been identified as part of the annual GB wide Network Options Appraisal (NOA) that National Grid undertake. This process takes a holistic view of all future projects to determine the most efficient reinforcements for the entire network
The maximum design envelope has been presented in the Scoping Report which constitutes an 80m wide temporary construction corridor with a 60m wide cable easement.
The highest point of the offshore wind turbine (the blade tip as it rotates) could be up to 403m above the sea (measured to Lowest Astronomical Tide (LAT)).
As all the wind turbines will be more than 54km offshore, only on the clearest days would any of the wind turbines be visible from the shore, and only the upper parts of the wind turbines. Based on the location of the Project, from most locations along the coast the Project will be hidden behind other existing wind farms.
Location
The outline offshore cable route and the corresponding onshore grid connection location for ODOW have been determined by National Grid Electricity System Operator (NGESO) as part of a Holistic Network Design (HND) for all new offshore wind connections. The HND is a new process, introduced as part of the Government’s Offshore Transmission Network Review (OTNR), which has balanced environmental, social and economic costs to determine the optimal connection points for new offshore wind farms. Until such a time that a preferred location is determined by NGESO, ODOW are appraising the two options recommended by NGESO in their July 2022 HND report.

Ecology
The Project is committed to delivering a positive legacy for local wildlife. It is for this reason that the avoidance of sensitive environmental receptors has been central to the design of the potential cable routes and placement of the respective Onshore Substations. An Environmental Assessment of onshore ecology, including local wildlife and birds, will be undertaken. This includes surveying the area to identify the presence and numbers of species. The Environmental Impact Assessment and supporting Development Consent documents submitted as part of the application will include mitigation measures where required to reduce any potential impacts to non-significant levels. These will be determined based on the species present and the specific requirements for each location. Further to the ES, the Project has also committed to provide biodiversity net gain, meaning that the Project will leave ecological habitats in a better state than before the Project.
