How transmission companies and organisations plan the route of new transmission lines near residential and commercial buildings; and 2. How transmission companies and organisations deal with requests to relocate (or underground) existing lines when residential or commercial development is planned, or is newly built, near ex-isting lines. These issues can be contentious, with many cases of citizens, environmental organisations and building developers lobbying electricity companies and organisations and politicians, to seek to have transmission lines located as far as possible away from buildings. Their motives may be fear of EMF, belief that visual impact will be negatively affected, or loss of monetary value of buildings or land proposed for building development. Objectors (citizens, building companies and politicians) may often give examples of practices in other countries to justify their position, with the electricity transmission company then having to research these alleged ‘best practices’. The WG would seek to produce data relating to electricity companies ’ policie
