We provide environmental support to grid connection and transmission infrastructure projects 

ASH work with transmission operators and developers providing environmental assessment services in the development of new grid connections and the reinforcement of existing transmission infrastructure. This has included carrying out environmental appraisals to review the implications of potential routes for overhead line or underground cables and options for potential new electricity substation sites.

Energy Distribution and Transmission

Our role in these projects spans the whole development process, from inception / feasibility, through options appraisal, screening / scoping, site layout and iteration, environmental assessment and site implementation.

We have also been involved in the environmental appraisal and submission of a number of substation planning applications, such as the approved Fetteresso Substation in Aberdeenshire (which will serve to connect the consented Mid Hill Wind Farm to the national grid) and Berryburn Substation in Moray (which will serve to connect the consented Berry Burn Wind Farm to the national grid).

Other substation submissions have been the result of grid re-enforcement requirements such as Crossaig (Kintyre), Knocknagael (Inverness-shire), Shin (Sutherland) and Dounreay (Caithness).

ASH have been retained to draft and co-ordinate construction environment management documents and landscape mitigation proposals (such as mounding and planting) to satisfy planning conditions for a number of these developments, as well as providing on-site advice and support as appropriate. We are currently providing such on-site monitoring and environmental advice for Fetteresso Substation, Connagil Substation, Strath Halladale to Dallangwell overhead line and Sloy Switching Station.
