Scottish floating wind farm in frame to be 'world's biggest' gets Highland green-light

Copenhagen Infrastructure Partners-led project on site of pioneering Dounreay Trì will start with single turbine pilot before being built out to full 100MW array

Scotland’s Pentland floating wind project – at 100MW in the frame to be world’s largest deepwater array – is formally moving ahead, following greenlighting by developer Highland Wind.

Sited 6.5km off the Caithness coast, the project, which will power some 70,000 homes in the region once producing in 2027, will launch with a single turbine pilot before being expanded into the planned full-scope development.

“We believe in an inclusive approach to developing our offshore wind projects, ensuring that local companies and communities gain the advantage from the opportunities these projects bring,” said Michael Hannibal, partner at Copenhagen Infrastructure Partners, majority-owner of Highland Wind.

“We’re committed to awarding Scotland’s supply chain with the local content work needed to support job creation and boost the country’s floating wind capabilities and experience.”

Announcement of the Pentland project’s go-ahead follows the recent confirmation that CIP will be bidding, in consortium with SSE Renewables and Marubeni, in Scotland’s ScotWind auction now underway.

Alan Hannah, managing director at COP UK, which is shepherding development activities for the Pentland floating wind project, said: “Floating wind projects are vital to the UK meeting its net zero targets.

“This is an exciting floating project for Scotland ahead of the ScotWind announcements early next year. Learnings and understandings from pre-commercial projects are key to the speedy commercialisation of floating wind in Scotland.”

The first phase of the Pentland project will see a single 8.6MW turbine installed, with construction anticipated in 2023, while the larger floating array project would get in to the water as early as2025.

The development site – which has consents from Marine Scotland in place for the pilot, a lease from the Crown Estate Scotland for an up-to-100MW project an a grid connection agreement – has already been closely scoped-out for the earlier Dounreay Trì demonstrator launched in 2016 that planned to use Hexicon’s innovative twin-turbine concept.
Highland Wind is working through the decisions-making process” on a choice of platform, Recharge reported last month. The developer said more recently: “Whilst the exact floating technology solutions are yet to be decided, a key consideration is building on existing technical expertise in Scotland to maximise local supply chains.”
Scotland is seen as a global market anchor-point for the floating wind industry, being home to two of Europe’s first three arrays – the 50MW Kincardine and the 30MW Hywind Scotland – and expected to add significantly to regional market growth via the ScotWind tender where much of the acreage is in water depths beyond the reach of conventional bottom-fixed offshore wind foundations.
The Global Wind Energy Council expects 16.5GW of floating turbines to be in the water by 2030, a dramatic increase from the 6.5GW it was anticipating only a year ago, with most of that growth coming in the second half of the decade when the sector, which currently has just over 100MW in place, is tipped for dramatic lift-off.
