Dear Mr. Miller
I apologise that you have had difficulty in contacting Burcote Wind with your specific questions concerning the Creggan Wind Farm proposal. There has been a technical issue with the email address provided on the project website and this has now been amended. Please direct any future correspondence to
enquiries@burcotewind.com and we shall endeavour to answer any specific questions about the project as quickly and accurately as we can.
We would actively encourage anyone interested in the proposal to visit the project website at
http://www.cregganwindfarm.com for information and updates about the project or to visit the community engagement event to be hosted at Glenbarr Hall on Thursday the 23rd February between 2pm and 7.30pm.
In reference to the specific questions you have submitted, here is an initial response.
Annual outputTangy wind farm was originally installed in 2003 then expanded in 2006. Our understanding is that, for compatibility reasons, the additional turbines were installed in 2006 but not brought online until June 2011. On this basis, the annual output in Megawatt-hours for 2006-2011 should be calculated according to the wind farm’s original installed capacity of 12.75 megawatts instead of the expanded capacity of 18.7 megawatts. Since 2006 the capacity factor for Tangy has been de-rated against a higher installed capacity. Publicly accessible figures for the period prior to its expansion show that Tangy wind farm’s capacity regularly exceeded 30%.
The capacity factor for Beinn An Tuirc wind farm has a nine-year average of 30.65% using Vestas V47-660kW turbines. By comparison, the Creggan wind farm proposal comprises the latest high efficiency three megawatt turbines. In the intervening time since the construction of Beinn An Tuirc and Tangy wind farms, the efficiency of turbines has improved dramatically as a result of progress in blade design, components and direct drive technology. Using modern turbines, a capacity factor of 40% is wholly achievable on the Creggan wind farm site, where our desktop studies indicate annual average wind speeds to be in the region of 10 metres per second. On-site wind speeds will be verified over the coming months using data from an anemometer mast.
It is true that the BWEA website calculations use a constant 30% Capacity Factor. That figure is representative of the average Capacity Factor for all wind farms in the UK.
However, the BWEA also states: "This is only an average estimation given that in many places, particularly Scotland and offshore, the wind speeds are higher leading to a greater electricity production per turbine, as power output is a cube of the wind speed."
We have opted to base our calculations for the Creggan wind farm proposal on local wind maps for the Kintyre area, since wind speeds and therefore output is expected to be much higher than the national average.
Homes poweredAs with all new wind farms, we would expect Creggan wind farm to supply electricity to the National Grid for use by all UK households. On this basis, we believe it is reasonable to use national figures for the whole of the UK to calculate the equivalent number of homes the wind farm could be expected to power. The number of homes quoted is designed to provide a meaningful illustration of what a defined number of units of electricity represents in terms of day-to-day electricity consumption for most consumers.
Community benefit fundThe community benefit fund currently being proposed to accompany Creggan wind farm is a guaranteed no-risk payment to the local community, calculated on the basis of a fixed sum of £3000 per megawatt of installed capacity, payable each year of the wind farm’s lifetime (limited to 25 years).
Burcote Wind is open to exploring other models for disseminating community benefit. We have started discussions with West Kintyre Community Council and other stakeholders in the local area. We are keen that the wind farm can provide a sustainable economic benefit to the community that can bring jobs, encourage tourism and improve opportunities for young people in the local area.
From publicly available information, we understand that Tangy wind farm provides a community benefit fund of around £8,640 per annum, equivalent to £462 per megawatt of installed capacity, whilst Beinn an Tuirc provides an annual community benefit fund of £21,000, equivalent to £692 per megawatt.
If consented, development of the Creggan wind farm proposal would require an up-front investment of between £90million to £100million. At the same time, a reduction in the ROC subsidy for onshore wind developments to the equivalent of 0.9 ROCs is being considered. The Renewable Obligation Scheme acts as a contribution towards the substantial up-front investment required to develop a wind farm. To put the effect of the RO scheme into context, all renewable energy generation in the UK last year had the effect of adding just £6 to the average electricity bill. The large increases in electricity costs last year came from wildly fluctuating gas prices and the wider deployment of Renewables will help insulate us from these in the future.
Site locationScottish Planning Policy refers to a guideline separation distance of up to 2km between areas of search for groups of wind turbines and the edge of towns, cities and villages, to reduce visual impact. However, the Policy also states that “Development plans should recognise that the existence of these constraints on wind farm development does not impose a blanket restriction on development, and should be clear on the extent of constraints and the factors that should be satisfactorily addressed to enable development to take place”, and that “decisions on individual developments should take into account specific local circumstances and geography.”
The turbine layout for the Creggan wind farm proposal is indicative at this stage and will go through many iterations before we put forward the final plan in our Planning Application. We will carefully assess any visual and landscape impacts the Creggan wind farm proposal may have and, if necessary, will adjust our proposals in light of the results. The results of the landscape and visual impact assessment will also be included as part of the environmental statement accompanying the planning application. We will also take into account feedback from the local community on the turbine layout and try to accommodate this into the final layout where we can.
Thank you for your interest in the Creggan wind farm proposal. If we can be of any further assistance or if you would like to discuss these points in further detail, please do not hesitate to contact Burcote Wind using the email address:
