The decision process with regard to the height and distribution of wind turbines aims to maximise annual energy production. This is achieved by assessing the effects that each turbine has on surrounding turbines in an effort to limit energy losses and turbulence within the wind farm. The extent of these effects is dependent on wind direction, wind velocity, turbine blade size and distance between wind turbines. Each wind turbine is located with the aim of minimising wake losses within the wind farm.

The wind turbines are positioned in such a way that in the unlikely event that they should fall, they would not damage the road or lines. This right of way does not create restrictions for other land use, such as land reclamation.

Layout within the wind farm area

An emphasis is placed on initiating the EIA process as quickly as possible during the preparation phase. This allows recommendations that were put forward during the process to be considered during the design phase of the wind farm.

The exact location of each wind turbine is not outlined in each proposal. The location of roads and collection stations is dependent on the final location of the wind turbines.

The EIA assumes that the area within each proposal can be utilised for the wind farm and that the shown layout is only an example.   The final layout for the area will be developed in the later stages of the project once the turbine type has been chosen.

Roads and crane platforms

An access road and 1,200 m2 crane platform by each wind turbine must be constructed. The Landvegur Road (26) is expected to remain the same. Roads will be constructed from the Landvegur Road and up to the wind turbines with minimum connections. Proposals 1 and 3 offer the option of constructing a new road for the general public, which would be constructed to the south of the wind turbines instead of through the wind farm. The construction of this public road would reduce the visual impact of the farm that travellers through the area would experience. This would be done in cooperation with the local municipality and the Icelandic Road and Coastal Administration (IRCA).

The figure shows the current research wind turbines, the layout of the roads and the scope of the foundation and crane platforms. Finishing work will be executed in a similar manner at the proposed wind farm.

The development of the wind farm

The speed of development follows the demand for electricity and the feasibility of development. The internal layout of the area will depend on the best conditions for energy generation based on the choice of wind turbine, the scope of road construction and the impact on the physical landscape.

The design of the wind farm will be developed in collaboration with the local municipality and licensors. The site plan will outline the internal organization of the wind farm based on further research, the type of wind turbine and the results of the EIA. In the impact assessment for the site plan (SEA) it will be possible to show the  visual impact based on this more detailed version.

Labour requirements

The development of the Búrfell Wind Farm requires specialised labour for the installation of wind turbines and general contractors for road construction and facilities development. The total number of man-years during the construction period is estimated to be approx. 200. In comparison, the total number of man-years for the Búðarháls Hydro Electric Project was 800. It is estimated that a total of 6 technicians will be required during the operational period of the wind farm.

Transport to and from the area

All equipment will be transported by ship to the port in the southwest of the country, probably in the capital area or at Þorlákshöfn. From there specialised transport vehicles will deliver the materials to the proposed project site. The project area can be accessed using the national highway system in the country. The distance from the metropolitan area is approximately 130 km and is approximately 95 km from Þorlákshöfn. Attempts will be made to minimise the impact on traffic during the transportation of equipment. A Construction Traffic Management Plan will be put in place.

Collection system for electricity generation

Electricity will be collected from the wind turbines via underground cables leading to collection stations. One possible option would be to build two collection stations, each capable of collecting 100 MW.  The electricity grid connection point will be an off-site grid connection that will be made via a buried cable.

Material extraction quarries

Potential quarries for the Búrfell Wind Farm have been investigated. The materials will be used for road construction, platforms and aggregate materials for concrete. The Icelandic Road and Coastal Administration and Landsvirkjun has used these quarries over the years. Landscaping and finishing work in material extraction areas will be in accordance with paragraph 2 of Article 13 of Planning Act No. 123/2010 on development licenses.
