Is this work relevant to all power lines or just the high voltage ones controlled by National Grid?
These guidelines relate primarily to existing 400kV and 275kV transmission lines – the transmission system operated by National Grid which connects the electricity generators’ power stations with the local networks of the electricity distribution companies. These are the pylons and lines that probably impact the most on the landscape and on public space, and that usually cannot be removed or re-routed. However, the principles outlined in this guidance may be useful in considering any such constraint to development because of the way they illustrate good site layout and design solutions.
