Inch Cape Wind Farm

Inch Cape is a proposed offshore offshore wind farm off the east coast of Scotland, approximately east of Arbroath, Angus. It is named after the nearby Inchcape reef. The project has a potential capacity of 1080 MW. It is being developed by Inch Cape Offshore Limited (ICOL), an equal joint venture between Edinburgh-based Red Rock Renewables and Irish ESB Group's Energy for Generations.

The Inch Cape site covers an area of around with water depths of . It is located off the coast of Angus, with the boundary of the site to the north-east of Inchcape and the Bell Rock Lighthouse. The Inch Cape windfarm is to the north of the Neart Na Gaoithe Wind Farm and south-west of the Seagreen Offshore Wind Farm.

When complete, the windfarm will have 72 Vestas V236-15.0MW turbines, up to high. It will also feature a 66/220 kV offshore substation. Power will be transmitted to shore via two 220 kV cables, with the onshore substation at the former Cockenzie power station in East Lothian, where it is connected to the National Grid. The subsea export cables are expected to be installed in 2025. Construction of the onshore substation commenced in early 2023. Between autumn 2024 and summer 2025, a section of the John Muir Way around the former power station needed to be diverted.

The Monopile foundations for the turbines will be up to long, with a maximum diameter of and mass of 2,500 tonnes. These will be installed by Jan De Nul, with work expected to commence late in 2025, using a newly built quayside at the Port of Leith.

Planning and consenting

In June 2011 ICOL was awarded an exclusivity agreement from The Crown Estate for the development area. This was in response to a 2008 call for proposals for offshore windfarms in Scottish coastal waters.

In 2014, the project gained the necessary consents for the offshore works, " Section 36" and Marine Licences, to build a windfarm of up to 110 turbines with a total power of 784 MW.

In 2016, the Royal Society for the Protection of Birds (RSPB) successfully challenged the plans to build the Inch Cape, Neart na Gaoithe, plus Seagreen Alpha and Bravo windfarms. This was reversed in May 2017 following appeal by the Scottish Government. In November 2017, RSPB Scotland was refused permission to appeal this decision in the Supreme Court.

A revised proposal was submitted in August 2018, for a reduced number of larger turbines, which was stated to improve the project economics. The proposed rotor diameter was increased to from the previous , with maximum tip height increased to from . However, the number of turbines was reduced to just 72 from the original 110, and the number of offshore substation platforms and export cables limited at two, rather than five and six previously. The revised proposal was granted in September 2019.

In August 2021, the Section 36 consent was amended to remove the 1 GW limit on the project size, which permits the use of more powerful turbines within the original size limits.

The project was awarded Contracts for Difference for 1080 MW under Allocation Round 4 in 2022, at 37.35 £₂₀₁₂/MWh. In September 2024, 266.11 MW of this was awarded a higher price of 54.23 £₂₀₁₂/MWh under the Offshore Wind Permitted Reduction scheme.

Construction

Siemens Energy were awarded the contract to construct the substations for the project, both offshore and onshore.{{Cite web , last=Memija , first=Adnan , date=2024-01-23 , title=Inch Cape Onshore Substation Work Kicks Off , url=https://www.offshorewind.biz/2024/01/23/inch-cape-onshore-substation-work-kicks-off/ , access-date=2025-03-02 , website=Offshore Wind , language=en-US

In January 2024, construction of the onshore substation started. The works are being undertaken for Siemens Energy by civil engineering contractor Careys.
