Overview
About the project
As the transmission license holder in the north of Scotland, we have a duty under Section 9 of the Electricity Act 1989 to facilitate competition in the generation and supply of electricity. We have obligations to offer non-discriminatory terms for connection to the transmission system, both for new generation and for new sources of electricity demand.
Under our Network Operators License this connection should be efficient, coordinated, and economic, whilst having the least possible impact on the environment
Subject to planning consent, we are required to connect the Muaitheabhal Wind Farm development located near to Eishken, To facilitate this, we are proposing to construct 9km of Low profile wood pole Overhead Line and 1km of underground cable and a substation situated at the windfarm. This will then connect into the proposed Balallan Switching station.
The average height of the trident poles is between 13 and 16 meters, up to a maximum of 18 meters, with an average span of between 70 and 100 meters.
At the Muaitheabhal connection point, a substation will be constructed this will consist of three buildings housing all electrical switchgear to protect it from the elements. These buildings will be of various sizes, two shall be approximately 40x20m, and one shall be approximately 40 x 55m with an approximate overall platform size of 140m x 85m.
• Permanent access requirements to the site will be dependent on the Site Option chosen.
How we’re embracing artificial intelligence (AI)
We intend to use AI to assist our experienced teams in the analysis of your feedback, so we can categorise key points raised more quickly. You can learn more about how we’re utilising AI on this dedicated web page.
