CIP puts plans for new floating Pentland project forward

Copenhagen Infrastructure Partners (CIP) are seeking advice from Scottish Ministers for a new floating wind farm. The ‘Pentland Floating Offshore Wind Farm (PFOWF)’ will be located 6 km off the coast of Dounreay, Caithness.

The project area was formerly reserved for the construction of the 8-12 MW Dounreay Trì wind farm by Hexicon AB, a leading Swedish floating offshore wind farm developer. Consent was granted in 2017 for installation of two turbines and single export cable but the project failed to start construction and missed out on Renewable Obligation Certificates (ROC).

CIP is now the majority shareholder and has reignited the project through its newly formed Special Purpose Vehicle (SPV) ‘Highland Wind Limited’.

The updated PFOWF will be in the same location as the original Dounreay Trì, within a 25 km2 search area, but up to 100 MW.

In December CIP submitted a scoping request from Marine Scotland on the necessary Environmental Impact Assessments. The report outlines CIP’s initial ambitions for the new project. Key design specs include:
-6-10 turbines of 10-16 MW with a rotor diameter of 170-240m, tip height of 192-270m and hub height of 107-150m;
-the concept for the floating Foundations, moorings and anchors is yet to be decided. Each foundation could support -either 1 or 2 turbines;
-up to 25km of 66 kV dynamic array cables;
-up to 10-20km, 110 kV export cabling.

PFOWF will connect to the grid at Dounreay – either to the existing 132 kV substation or the 275 kV Dounreay West substation which is consented but is yet to be constructed (planned completion Q3 2022).

Fabrication activities are planned to commence upon financial close in 2024, installation and commissioning of the turbines is anticipated to take 6 months in 2026.

Highland Wind Limited are also considering using the existing consent for the Dounreay Trì project to build a Demonstrator in advance of the main PFOWF. The final details of the Demonstrator have not been determined but will be within the original parameters. The Demonstrator project infrastructure will be consented and constructed separately from the broader PFOWF but will ultimately form part of the wider array i.e. contribute to the overall 100 MW. Highland Wind Limited is currently in consultation with Marine Scotland regarding potential required variations to the existing Dounreay Trì Project consent to construct and operate the proposed Demonstrator. It is currently envisaged that the Demonstrator would be constructed and operational by mid-2023.

The design life of the turbines and other major components of the PFOWF is expected to be a minimum of 25 years. The primary objective of the Project is to test and demonstrate a technology solution for floating offshore wind in Scotland.
