ASH coordinated the environmental impact assessment for the proposed Chaorach Hydroelectric Scheme

Located within Loch Lomond and the Trossachs National Park, this 2 Megawatt run-of -river hydroelectric scheme will generate electricity when there is sufficient natural water flow in the river.

The hydroelectric scheme is located to the south of the River Dochart, on the lower slopes of Ben More. Situated within the northern boundaries of the Ben More and Stob Binnein Site of Special Scientific Interest, and upstream of the River Tay Special Area of Conservation.

Key Tasks

Screening and Scoping

EIA coordination and project management

Landscape and visual impact assessment

Landscape design

Stakeholder consultation


What we did

Development in such a sensitive area required detailed environmental studies into scheme alternatives and mitigation measures for the final hydroelectric scheme design.

Close contact with landowners and key consultees was maintained throughout the assessment process and a thorough scoping exercise was carried out to ensure all potential impacts on the environment were considered.

A draft Code of Landscape Reinstatement and Construction Practice was produced detailing specific conditions relating to:

  • The siting of working areas
  • The protection of species
  • Soil management strategy
  • Prevention of pollution to watercourses
  • The means by which site monitoring should occur

This code ensures the findings and recommendations of the environmental statement are implemented during construction of the hydroelectric scheme.

The planning application for the Chaorach hydroelectric scheme was submitted in March 2007, and consent was received from Scottish Ministers in December 2008.
