The initial phase of civil engineering work to improve the site access across both private and public land was completed by Tulloch Civil Engineering Ltd. The remainder of the civil engineering work to construct the wind farm access tracks and turbine bases commenced during May 2008. The works were undertaken by civil engineering contractor R J McLeod Ltd. The new 275 kV substation constructed by Scottish Hydro Electric Transmission Ltd within the wind farm was completed and energized on 20th December 2007. The substation utilizes one large 90 MVA transformer. The substation which was built directly adjacent to the existing Beauly-Dounreay 275 kV transmission line, connects the wind farm electrical output to the national grid. The turbines have been built and installed by German company Nordex AG, one of the world’s leading turbine suppliers. The large turbine components (blades, towers and nacelles) were delivered to site via the port of Invergordon.
