Is situated on the northwest side of the Australian Capital Territory border abutting the town of Williamsdale in the Southern Tablelands region of New South Wales, Australia.

To the west of Williamsdale is an outcrop of Upper Silurian Laidlaw Volcanics dark grey rhyodacitic and dacitic crystal tuff.

[5] In response to increasing operating costs for general aviation users of Canberra Airport, a proposal was made by the ACT Government in 2005 to develop a dedicated secondary airfield for the Territory.

[6] The site recommended was to the west of the Monaro Highway at Williamsdale, and would include aircraft hangars, maintenance and fuel facilities, and a 1000m grass runway.

[7] As of 2012, the ACT government has declined to develop the facility, but has made the cost benefit analysis and feasibility study reports available should private enterprise wish to consider the project.

[8] The land to be occupied by the proposed solar farm was acquired by ActewAGL in 2009,[9] and was considered preferable to an alternative site in the West Belconnen district.

[11] Subsequently, Elementus Energy which had owned the project sold it to a subsidiary of Melbourne-based Impact Investment Group, and the German company ib vogt GmbH was contracted for the construction.
