The Holford Rules Guidelines we follow for the routeing of new high voltage overhead transmission lines.
The Horlock Rules Guidelines we follow for the siting of new substations.
National Grid’s commitments when undertaking works in the UK Our stakeholder, community and amenity policy, which sets out our ten commitments when undertaking electricity and gas work in the UK.
Our approach to the design and routeing of electricity transmission lines This document sets out the process that we use to take projects forward: the stages of consultation; the people and organisations that we consult with, and the way in which we appraise and narrow down the options. Our approach to options appraisal This document provides more detail on the various assessments we undertake at different stages of the project. Undergrounding high voltage electricity transmission lines - the technical issues Information on the technical issues associated with undergrounding high voltage transmission lines. Electricity transmission cost study - National Grid’s view How the Institution of Engineering and Technology and Parsons Brinckerhoff’s report (Jan 2012) on the costs of new electricity transmission infrastructure compares with National Grid’s view.Electric and Magnetic Fields (EMFs) - The facts Produced by the Energy Networks Association, this guide explains the research undertaken with regard to electric and magnetic fields (EMFs) and health and discusses the conclusions of that research.
