Our electricity assets include overhead lines, pylons, underground cables, and transmission substations. 

For electrical assets, we do not authorise or agree safe systems of work with developers and contractors. However, we will advise on issues such as electrical safety clearances and the location of towers and cables. We also work with developers to minimise the impact of any of our assets that are nearby.
