The National Offshore Wind Turbine Test facility (NOWTTF) at Hunterston is the UK’s only onshore test facility for offshore wind turbines. It has been instrumental in securing Scotland’s place as an international leader in offshore wind energy research and development.

In January 2017, with the consent due to expire in October 2017, an application to extend the five year life of the site for a further two years was submitted to North Ayrshire Council. The purpose of this application was to facilitate completion of the test period and allow SSE to assist with the continued development of offshore wind technology in Scotland.

In light of the recent decision of North Ayrshire Council to delay a decision on a time extension for the Hunterston Test Facility, SSE Generation Ltd submitted a planning appeal, on Friday 21 July, to the Scottish Government.

The Statement of Appeal sets out the full detail of the appeal and includes an overview of the matters that SSE asks to be taken into account in the determining process.  

Quick overview

Siemens 6MW direct drive turbine – tip height of 177m with a rotor diameter of 154m

Mitsubishi 7MW Sea Angel turbine – tip height of 193.5m with a rotor diameter of 167m

The Hunterston facility has been instrumental in securing Scotland's place as an international leader in offshore wind energy research and development. To date the Hunterston project has injected £32.4m into the Scottish economy with £4.1m of this in North Ayrshire.

During the existing testing period the facility has allowed Siemens to use the 6MW test machine to refine their 7MW turbine which will be deployed at the Beatrice offshore wind farm in the Outer Moray Firth as well as other UK offshore wind farms. Mitsubishi testing has included the Artemis hydraulic system which has secured employment and provided excellent data for future offshore turbine designs and projects.

Since the project’s community fund began in 2013, £238,000 has been invested in grant payments across 102 local projects.  The fund has been welcomed by a broad variety of local clubs, groups, festivals and schools to run events, buy new equipment and improve facilities.

Latest news

SSE is looking to extend the current planning consent for the Hunterston offshore wind turbine test facility in North Ayrshire by two years.

The extension to the consent period would enable a full five year operating window and the chance to further refine the important data and findings following early stage issues including grid connection and construction delays. This meant that testing of the turbines only fully commenced on 1 March 2014.

Following the decision of North Ayrshire Council to further delay their decision on the application SSE has submitted a planning appeal to the Scottish Government. The decision to appeal was taken given the time limit on the current consent and was necessary to offer the site an opportunity to complete its instrumental work in the offshore wind industry.

If successful this extension to the test site will allow SSE to assist with the continued development of offshore wind technology as well as providing a facility with Siemens for training future offshore wind technicians.

Project information

Consented in February 2012, the Hunterston Offshore Wind Turbine Test facility, located in North Ayrshire, is the UK’s first onshore test site for offshore wind turbines. Construction works commenced in March 2013 with RJ McLeod appointed as the Principal Contractor for the project. SSE is now working closely with supply chain partners Siemens and Mitsubishi Heavy Industries Europe, Ltd following construction to test their latest turbine technology on two of the berths at the site. To date, no turbine manufacturer has committed to testing on the third berth, which was due to be operated by Scottish Enterprise who committed part funding from the National Renewables Infrastructure Fund towards the project. 

The development of the Hunterston test site has also been supported by invaluable funding from UK government departments – Department for Business, Energy and Industrial Strategy (BEIS). This funding forms part of the Efficient Offshore Wind Programme.

The Report by DTU Wind Energy, which can be found below under Important Documents, is aimed at assessing whether a lidar placed on the nacelle or the transition piece (TP) of an offshore wind turbine could be used for power curve verification instead of a met mast. This report presents the results obtained with both the TP lidar and the nacelle lidar  installed on an offshore wind turbine in the Greater Gabbard wind farm, located in the North Sea about 23 km from Lowestoft, Suffolk. The site, the measurement set up and the dataset collected are described within the first section of the report. The performances of each lidar are then discussed and finally the power curves measured by the two lidars are compared to the met mast power curve in terms of AEP and uncertainty. This work has been supported by funding awarded to Hunterston NOWTTF by the Department of Energy and Climate Change and the Technology Strategy Board’s Offshore Wind Component Technologies Development and Demonstration Scheme.

Hunterston’s wind resource, which replicates offshore conditions, coupled with its existing grid connection, make it an ideal site for the testing facility which has a key role in developing the UK’s offshore wind supply chain. The advantage of testing turbines on land is that it permits the manufacturer 24 hour access to make modifications and repairs, which is critical particularly for early series prototype turbines.

As a responsible owner and operator of renewable energy technology SSE takes all complaints relating to any environmental impact of its operations very seriously.  SSE has investigated a small number of complaints raised to date in consultation with North Ayrshire Council (NAC), and NAC have advised that there is no ongoing statutory nuisance pertaining to the site.  SSE and NAC Environmental Health  department have investigated noise levels and found that there is no correlation between the wind turbine operation and measured low frequency noise levels and also that the overall levels of low frequency noise measured would not be expected to cause adverse impact. NHS Ayrshire and Arran have also investigated the health concerns and concluded that there is no correlation between the complaints and turbine operation.

The facility will have a key role in developing the UK’s offshore wind supply chain by allowing manufacturers to demonstrate the reliability of the next generation of larger capacity turbines ahead of deployment offshore.

Press release

SSE submits Hunterston planning appeal to the Scottish Government

24 July 2017

SSE has submitted a planning appeal to the Scottish Government following the decision of North Ayrshire Council to repeatedly delay a decision on a time extension for the Hunterston Test Facility.

With the Hunterston site’s current planning application due to expire in October 2017 the decision to appeal this was necessary to offer the site an opportunity to complete its instrumental work in the offshore wind industry.

As the only functioning onshore wind test facility for offshore wind turbines in the UK Hunterston has helped put North Ayrshire and Scotland in a strong position to benefit economically from the technology as the sector develops. To date the site has generated a total of £4.1million GVA for North Ayrshire and £32.4million GVA for the Scottish economy.

Following the submission of the Section 42 Application in January, SSE and its appointed consultants, have worked diligently and engaged in dialogue with Council officials, statutory consultees and local residents.

Sean Kelly, Project Manager at SSE said: ““As the only functioning onshore test facility for offshore wind turbines in the UK, Hunterston has delivered a number of benefits for the industry and local community.

“We were disappointed with the decision of North Ayrshire Council to again delay the decision on a time extension for the Hunterston Test Facility, despite its own officials’ recommendation that the consent extension be approved. Our decision to submit an appeal to the Scottish Government is our only option to take the project forward given the time limit on the current consent. We believe that the site still has a lot more to bring, both to the industry and the local community, and we hope we will be granted the appeal.”

As a responsible owner and operator of renewable energy technology SSE takes all complaints relating to any environmental impact of its operations very seriously. SSE has investigated a small number of complaints raised to date in consultation with North Ayrshire Council (NAC), and NAC have advised that there is no ongoing statutory nuisance pertaining to the site. SSE and NAC Environmental Health department have investigated noise levels and found that there is no correlation between the wind turbine operation and measured low frequency noise levels and also that the overall levels of low frequency noise measured would not be expected to cause adverse impact. NHS Ayrshire and Arran have also investigated the health concerns and concluded that there is no correlation between the complaints and turbine operation.

The planning consent includes six planning conditions relating to noise. These conditions outline the overall acceptable noise limit, the action to be undertaken in the event of a complaint regarding noise levels and also the action to be undertaken in the event of any exceedance of the noise limits. An additional planning condition relating to noise has also been proposed by North Ayrshire Council.

SSE seeks time extension for Hunterston offshore wind test site


17 January 2017


SSE is looking to extend the current planning consent for the Hunterston offshore wind turbine test facility in North Ayrshire by two years. The site, currently home to a 6MW Siemens offshore wind turbine and a Mitsubishi 7MW Sea Angel offshore turbine, is the only functioning national onshore test facility for offshore turbines in the UK.


The extension to the consent period would enable a full five year operating window and the chance to further refine the important data and findings following early stage project delays. The Hunterston facility has been instrumental in securing Scotland's place as an international leader in offshore wind energy research and development. To date the Hunterston project has injected £32.4m into the Scottish economy with £4.1m of this in North Ayrshire.


Sean Kelly, Hunterston Project Manager, said; “The Hunterston test site is a unique facility that we believe still has much more to give to the offshore wind industry. The team is hopeful that we can extend the site for another two years to complete its current testing and research programme.

“The Hunterston site has not only brought benefits to the offshore wind industry and economic benefit to the region, the communities close to the wind farm have also benefited from the Hunterston Community Fund which is providing £250,000 over the current five years of the project.”

During the existing testing period the facility has allowed Siemens to use the 6MW test machine to refine their 7MW turbine which will be deployed at the Beatrice offshore wind farm in the Outer Moray Firth as well as other UK offshore wind farms. Mitsubishi testing has included the Artemis hydraulic system which has secured employment and provided excellent data for future offshore turbine designs and projects.

Since the project’s community fund began in 2013, £183,180 has been invested in grant payments across 68 local projects.  The fund has been welcomed by a broad variety of local clubs, groups, festivals and schools to run events, buy new equipment and improve facilities.

If successful this extension to the test site will allow SSE to assist with the continued development of offshore wind technology as well as providing a facility with Siemens for training future offshore wind technicians.

Hunterston Siemens 600 300

First power exported from Hunterston Offshore Wind Turbine Test Facility

SSE Renewables, the renewable energy development division of SSE, reached a significant milestone after electricity was exported for the first time from its offshore wind turbine test facility at Hunterston.

Incorporating its latest offshore turbine technology, the Siemens SWT-6.0-154 177 metre high 6 Megawatt (MW) direct drive wind turbine began generating clean wind powered electricity in March 2014.

Ian Flannagan, SSEs Project Construction Manager, said “It’s great to see the Siemens wind turbine generating electricity for the first time which is testament to the hard work and commitment shown by everyone involved in the project. We are busy preparing the site ahead of the second turbine, a Mitsubishi SeaAngel 7MW offshore wind model, arriving in a few months time.”

The Hunterston site, on the North Ayrshire coast, has similar wind conditions to those found offshore, access to the Grid and an adjacent jetty for facilitating component deliveries making it an ideal location for turbine manufacturers to test their latest turbine equipment before deploying it offshore.

Clark MacFarlane, Managing Director, Siemens Wind Power Offshore UK&I said: “We are delighted with the news of first power for our 6MW turbine at Hunterston. This is another important milestone for our next generation wind turbine technology. The SSE and Siemens team has worked extremely hard to get to this point and should feel proud of their achievement in delivering this important clean energy project.”

The project, the UK’s first onshore test site for offshore turbines, is being supported by Scottish Enterprise, the Department for Energy and Climate Change (DECC) and the Department of Business, Innovations and Skills (BIS) recognising its significance in helping to establish Scotland as a centre of expertise in offshore wind development.

Energy and Climate Minister, Greg Barker said: “SSE Renewable’s test site for offshore wind turbines is an exciting and innovative project that will help the country take another step towards delivering £110 billion investment into our energy sector while helping to support local jobs.

“Our long term economic plan is not only working, it is supporting the development of home-grown energy technologies that deliver cleaner, more affordable energy for hardworking consumers, including £15 million to further support innovative offshore wind projects.”

Construction work continues at the second berth on site preparing the foundation for the Mitsubishi turbine which is expected to arrive on site for assembly and commissioning in summer 2014.

The third berth will be operated by Scottish Enterprise and will be leased to a turbine manufacturer which has firm plans to invest in the Scottish offshore wind supply chain.
