Highland Wind and Cierco have filed supply chain statements for their respective Pentland and Forthwind floating wind demonstrators off Scotland.
Highland Wind, a joint venture of Copenhagen Infrastructure Partners and Hexicon, has said it anticipates £419m of lifetime expenditure on the project in the UK.
“This is in line with our ambitious target for 40% to 60% lifetime UK content, which is unprecedented figures for floating wind in the UK to date”, it said.
An additional £372m is likely to be spent in the EU with £94m of expenditure placed elsewhere.
Most of the EU expenditure will be in manufacturing and fabrication, which accounts for £246m compared to £123m in the UK.
Cierco has meanwhile said its Forthwind floater, which will comprise two unspecified next generation turbines, will generate investment of £60m during construction, though just £20m of this is expected to be spent within Scotland.
“There is potential for the entire project supply chain, excluding the turbine and specialised heavy lift vessels, being procured in and supplied by local UK and Scottish companies”, the document notes.
“To this end, Cierco has engaged with cable manufacturers & installers, foundation designers, foundation manufacturers & transportation and logistics companies, onshore electrical infrastructure companies and contractors all based in the UK.
“Excluding the wind turbine supply & specialised heavy lift vessel & craneage operators, Forthwind has the potential to realise 36% total UK & Scottish supply chain during construction.”
Overall, Cierco expects £25.8m of supply chain investment throughout the lifetime of the pilot project, compared to £39.3m ibn the rest of Europe.
The majority of European expenditure will be made in manufacture and fabrication as well as installation, accounting for £19m and £19.8m of spend respectively.
